This application is a continuation of U.S. patent application Ser. No. 13/493,722 filed Jun. 11, 2012 (now U.S. Pat. No. 8,660,278 issued Feb. 25, 2014) which is a continuation of U.S. patent application Ser. No. 12/464,310 filed May 12, 2009 (now U.S. Patent No. 8,224.013 issued Jul. 17, 2012) which is a continuation-in-part of U.S. patent application Ser. No. 11/845,712 filed Aug. 27, 2007, the contents of which are hereby incorporated in their entirety.
BACKGROUND OF THE INVENTIONA digital audio player (DAP), more commonly referred to as an MP3 player, is a consumer electronics device that stores, organizes and plays audio files. Some DAPs are also referred to as portable media players as they have image-viewing and/or video-playing support. The MP3 player is the most recent in an evolution of music formats that have helped consumers enjoy their tunes. Records, 8-track tapes, cassette tapes and CDs—none of these earlier music formats provide the convenience and control that MP3 players deliver. With an MP3 player in hand or pocket, a consumer can create personalized music lists and carry thousands of songs wherever they go.
The MP3 file format revolutionized music distribution in the late 1990s, when file-swapping services and the first portable MP3 players made their debut. MP3, or MPEG Audio Layer III, is one method for compressing audio files. MPEG is the acronym for Moving Picture Experts Group, a group that has developed compression systems for video data, including that for DVD movies, HDTV broadcasts and digital satellite systems.
Using the MP3 compression system reduces the number of bytes in a song, while retaining sound that is near CD-quality. Consider that an average song is about four minutes long. On a CD, that song uses about 40 megabytes (MB), but uses only 4 MB if compressed through the MP3 format. On average, 64 MB of storage space equals an hour of music. A music listener who has an MP3 player with 1 GB (approximately 1,000 MB) of storage space can carry about 240 songs or the equivalent of about 20 CDs. Songs stored on traditional CDs are already decompressed, so it takes more CDs to store the same amount of songs. (Some CDs support MP3 files.)
DAPs find natural uses such as listening to music or instructional audio during workouts. However the problem is that many workouts tend to be intense and involve different activities. However, conventional MP3 player can get in the way of activity and can require wrapping the player on the arm or the leg. Moreover, DAPs use headphones that can fall out while the users run, jog or jump.
SUMMARY OF THE INVENTIONIn one aspect, an intra-oral digital audio player includes a mouth wearable housing; a data storage device positioned in the mouth wearable housing to store digital audio; a transducer mounted on the mouth wearable housing and in vibratory communication with one or more teeth; and a linking unit to receive audio content and coupled to the data storage device.
In another aspect, a method for rendering audio content includes storing audio content in a data storage device positioned in a mouth wearable housing; intraorally wearing the mouth wearable housing; and vibrating one or more teeth to play the audio content.
In another aspect, a digital audio player device can be attached, adhered, or otherwise embedded into or upon a removable oral appliance or other oral device to form an intraoral MP3 player. In another embodiment, the device provides an electronic and transducer device that can be attached, adhered, or otherwise embedded into or upon a removable oral appliance or other oral device to form a DAP. Such an oral appliance may be a custom-made device fabricated from a thermal forming process utilizing a replicate model of a dental structure obtained by conventional dental impression methods. The electronic and transducer assembly may receive incoming sounds either directly or through a receiver to process and amplify the signals and transmit the processed sounds via a vibrating transducer element coupled to a tooth or other bone structure, such as the maxillary, mandibular, or palatine bone structure.
Advantages of preferred embodiments may include one or more of the following. The bone conduction DAP is easy to wear and take off in use, and is further inconspicuous in appearance during the user's wearing thereof. The device can be operated within the oral cavity, minimizing weight and size discomfort for the wearer. Comparing with headphones, the device avoids covering the ears of the listener. This is important if (a) the listener needs to have the ears unobstructed (to allow them to hear other sounds in the environment), or (b) to allow them to plug the ears (to prevent hearing damage from loud sounds in the environment). The system is a multi-purpose communication platform that is rugged, wireless and secure. The system provides quality, hands-free, yet inconspicuous entertainment capability for outdoor activities.
The DAP 1 can be remotely controlled through a handheld controller (not shown). For example, the handheld controller allows the user to adjust playback volume, play and pauses and navigate between tracks. In one embodiment, a squeeze control allows the user to pause/play (single squeeze) and skip to the next track (double squeeze). In another embodiment, a bite control allows the user to pause/play (single bite) and skip to the next track (double bite).
The memory can be solid-state memory or can be a mechanical memory such as a Microdrive, available from IBM. The advantage to solid-state memory is that there are no moving parts, which means better reliability and no skips in the music. However, the Microdrive type memory provides larger capacity to store more songs.
Other components of the player that are not shown can include the following: USB data port, microprocessor, digital signal processor (DSP), display, playback controls, audio port, amplifier, and power supply, for example. The microprocessor controls the operation of the player. It monitors user input through the playback controls, displays information about the current song on the LCD panel and sends directions to the DSP chip that tells the DSP exactly how to process the audio. To do this, the player retrieves the song from memory 6, decompresses the MP3 encoding using the DSP if needed. The player then runs the decompressed bytes through a digital-to-analog converter into sound waves and amplifies the analog signal, and drives the transducer to contact the tooth or teeth and allow the song to be heard through bone conduction.
In certain embodiments, the players also have built-in AM or FM radio tuner, providing users with an additional source of entertainment. Radio listeners can record the tunes from their favorite stations in the MP3 format, among others, and add the song to their playlist. In yet other embodiments, the players include an FM transmitter to playback the stored music on an external FM radio using unused frequencies.
The music content can be purchased from stores such as Apple's iTunes, or alternatively the user can use a ripper to copy songs from CDs to the memory. An MP3 encoder can compress the song into the MP3 format to be played from an MP3 player.
Although MP3 is perhaps the most well-known file format, there are other file formats that can be played on MP3 players. While most MP3 players can support multiple formats, not all players support the same formats. Here are a few of the file formats that can be played on different players:
-
- WMA—Windows Media Audio
- WAV—Waveform Audio
- MIDI—Music Instrument Digital Interface.
- AAC—Advanced Audio Coding
- Ogg Vorbis—A free, open and un-patented music format
- ADPCM—Adaptive Differential Pulse Code Modulation
- ASF—Advanced Streaming Format
- VQF—Vector Quantization Format
- ATRAC—Sony's Adaptive Transform Acoustic Coding 3
The DAP 1 can be used for swimming or in wet environment activities. The DAP 1 can be wirelessly connected to other devices via RF or electromagnetic, Bluetooth for either real time data transfer or sending data to the memory.
The DAP 1 can be a custom oral device. The device can include a housing having a shape which is conformable to at least a portion of at least one tooth; an actuatable transducer disposed within or upon the housing and in vibratory communication with a surface of the at least one tooth; and a wireless communication transceiver coupled to the transducer to provide received sound to the user and to provide communication for the user. The headset can be an oral appliance having a shape which conforms to the at least one tooth. The transducer can include an electronic assembly disposed within or upon the housing and in communication with a transducer. The linking unit 8 can be a transceiver compatible with an 802 protocol, cellular protocol, or Bluetooth protocol. In other embodiments, the device provides an electronic and transducer device that can be attached, adhered, or otherwise embedded into or upon a removable oral appliance or other oral device to form a medical tag containing user identifiable information. Such an oral appliance may be a custom-made device fabricated from a thermal forming process utilizing a replicate model of a dental structure obtained by conventional dental impression and/or imaging methods. The electronic and transducer assembly may receive incoming sounds either directly or through a receiver to process and amplify the signals and transmit the processed sounds via a vibrating transducer element coupled to a tooth or other bone structure, such as the maxillary, mandibular, or palatine bone structure.
The computer 2 can communicate with the linking unit 8 through a USB connection, among others. The USB connection can be activated when the device 1 is plugged into a recharging station 3 for recharging the battery in the DAP 1. In one embodiment, the DAP 1 can be mounted on a battery charging system for use with an induction charger to charge the intraoral appliance 1. The battery charging system can charge a number of devices. Accordingly, a plurality of such devices can be simultaneously, and efficiently, charged using a single induction charger.
The recharging station 3 can include a base charger coil with an open end defined to receive the DAP charger coil portion. When an energy storage device such as a battery needs to be recharged, the appliance charger coil portion is placed on the open end of the charger base so that the appliance charger coil and the base charger coil in combination complete an electromagnetic flux for inductive charging.
In one embodiment, the coil portion picks up electromagnetic energy emanating from the charger base station. The energy is in the form of electrical current which is provided to a charger regulator. The charger regulator boosts the voltage and smoothes out variations in the received energy using one or more filters. One or more filters can be used to remove electrical noise. The regulated DC output is provided to a charger which converts the energy into a suitable form for charging a energy storage device such as a super-capacitor or a battery, among others. The charger can be optimized for different battery technology. For example, NiCad batteries require a certain set charging characteristics, and Lithium Ion batteries require another set charging characteristics. The charger customizes the energy provided by the charger regulator for the specific chemistry or requirements of the battery to optimize the battery charging operation. The connection between the charger and the battery can be separated after charging to minimize size and/or weight of the portable appliance. The energy from the battery is provided to a second regulator that provides the voltage needed by the electronics in the DAP appliance.
In one embodiment, the DAP has a housing having a shape which is conformable to at least a portion of at least one tooth; an actuatable transducer disposed within or upon the housing and in vibratory communication with a surface of the at least one tooth; and a wireless communication transceiver coupled to the transducer to provide received sound to the user and to provide communication for the user. The DAP device can be an oral appliance having a shape which conforms to the at least one tooth. An electronic assembly can be disposed within or upon the housing and which is in communication with the transducer.
In another embodiment, the device 1 provides an electronic and transducer device 9 that can be attached, adhered, or otherwise embedded into or upon a removable oral appliance or other oral device to form a medical tag containing user identifiable information. Such an oral appliance may be a custom-made device fabricated from a thermal forming process utilizing a replicate model of a dental structure obtained by conventional dental impression methods. The electronic and transducer assembly may receive incoming sounds either directly or through a receiver to process and amplify the signals and transmit the processed sounds via a vibrating transducer element coupled to a tooth or other bone structure, such as the maxillary, mandibular, or palatine bone structure.
As shown in
Generally, the volume of electronics and/or transducer assembly 16 may be minimized so as to be unobtrusive and as comfortable to the user when placed in the mouth. Although the size may be varied, a volume of assembly 16 may be less than 800 cubic. millimeters. This volume is, of course, illustrative and not limiting as size and volume of assembly 16 and may be varied accordingly between different users.
Moreover, removable oral appliance 18 may be fabricated from various polymeric or a combination of polymeric and metallic materials using any number of methods, such as computer-aided machining processes using computer numerical control (CNC) systems or three-dimensional printing processes, e.g., stereolithography apparatus (SLA), selective laser sintering (SLS), and/or other similar processes utilizing three-dimensional geometry of the user's dentition, which may be obtained via any number of techniques. Such techniques may include use of scanned dentition using intra-oral scanners such as laser, white light, ultrasound, mechanical three-dimensional touch scanners, magnetic resonance imaging (MRI), computed tomography (CT), other optical methods, etc.
In forming the removable oral appliance 18, the appliance 18 may be optionally formed such that it is molded to fit over the dentition and at least a portion of the adjacent gingival tissue to inhibit the entry of food, fluids, and other debris into the oral appliance 18 and between the transducer assembly and tooth surface. Moreover, the greater surface area of the oral appliance 18 may facilitate the placement and configuration of the assembly 16 onto the appliance 18.
Additionally, the removable oral appliance 18 may be optionally fabricated to have a shrinkage factor such that when placed onto the dentition, oral appliance 18 may be configured to securely grab onto the tooth or teeth as the appliance 18 may have a resulting size slightly smaller than the scanned tooth or teeth upon which the appliance 18 was formed. The fitting may result in a secure interference fit between the appliance 18 and underlying dentition.
In one variation, with assembly 14 positioned upon the teeth, as shown in
The transmitter assembly 22, as described in further detail below, may contain a music data storage assembly as well as a transmitter assembly and may be configured in any number of shapes and forms worn by the user, such as a watch, necklace, lapel, phone, belt-mounted device, etc.
Power supply 36 may be connected to each of the components in transmitter assembly 22 to provide power thereto. The transmitter signals 24 may be in any wireless. form utilizing, e.g., radio frequency, ultrasound, microwave, Blue Tooth® (BLUETOOTH SIG, Bellevue, Wash.), etc. for transmission to assembly 16. Assembly 22 may also optionally include one or more input controls 28 that a user may manipulate to adjust various acoustic parameters of the electronics and/or transducer assembly 16, such as acoustic focusing, volume control, filtration, muting. frequency optimization, sound adjustments, and tone adjustments, etc.
The signals transmitted 24 by transmitter 34 may be received by electronics and/or transducer assembly 16 via receiver 38, which may be connected to an internal processor for additional processing of the received signals. The received signals may be communicated to transducer 40, which may vibrate correspondingly against a surface of the tooth to conduct the vibratory signals through the tooth and bone and subsequently to the middle ear to facilitate hearing of the user. Transducer 40 may be configured as any number of different vibratory mechanisms. For instance, in one variation, transducer 40 may be an electromagnetically actuated transducer. In other variations, transducer 40 may be in the form of a piezoelectric crystal having a range of vibratory frequencies, e.g., between 250 to 4000 Hz.
Power supply 42 may also be included with assembly 16 to provide power to the receiver, transducer, and/or processor, if also included. Although power supply 42 may be a simple battery, replaceable or permanent, other variations may include a power supply 42 which is charged by inductance via an external charger. Additionally, power supply 42 may alternatively be charged via direct coupling to an alternating current (AC) or direct current (DC) source. Other variations may include a power supply 42 which is charged via a mechanical mechanism, such as an internal pendulum or slidable electrical inductance charger as known in the art, which is actuated via, e.g., motions of the jaw and/or movement for translating the mechanical motion into stored electrical energy for charging power supply 42.
In another variation of assembly 16, rather than utilizing an extra-buccal transmitter, DAP assembly 50 may be configured as an independent assembly contained entirely within the user's mouth, as shown in
In order to transmit the vibrations corresponding to the received auditory signals efficiently and with minimal loss to the tooth or teeth, secure mechanical contact between the transducer and the tooth is ideally maintained to ensure efficient vibratory communication. Accordingly, any number of mechanisms may be utilized to maintain this vibratory communication.
In one variation as shown in
An electronics and/or transducer assembly 64 may be simply placed, embedded, or encapsulated within housing 62 for contacting the tooth surface. In this variation, assembly 64 may be adhered against the tooth surface via an adhesive surface or film 66 such that contact is maintained between the two. As shown in
Aside from an adhesive film 66, another alternative may utilize an expandable or swellable member to ensure a secure mechanical contact of the transducer against the tooth. As shown in
Another variation is shown in
In yet another variation, the electronics may be contained as a separate assembly 90 which is encapsulated within housing 62 and the transducer 92 may be maintained separately from assembly 90 but also within housing 62. As shown in
In other variations as shown in
In yet another variation shown in
Another variation for a mechanical mechanism is illustrated in
In yet another variation, the electronics 150 and the transducer 152 may be separated from one another such that electronics 150 remain disposed within housing 62 but transducer 152, connected via wire 154, is located beneath dental oral appliance 60 along an occlusal surface of the tooth, as shown in
In the variation of
In yet another variation, an electronics and/or transducer assembly 170 may define a channel or groove 172 along a surface for engaging a corresponding dental anchor 174, as shown in
In yet another variation,
Similarly, as shown in
In yet other variations, vibrations may be transmitted directly into the underlying bone or tissue structures rather than transmitting directly through the tooth or teeth of the user. As shown in
In yet another variation, rather utilizing a post or screw drilled into the underlying bone itself, a transducer may be attached, coupled, or otherwise adhered directly to the gingival tissue surface adjacent to the teeth. As shown in
For any of the variations described above, they may be utilized as a single device or in combination with any other variation herein, as practicable, to achieve the desired hearing level in the user. Moreover, more than one oral appliance device and electronics and/or transducer assemblies may be utilized at any one time. For example,
Moreover, each of the different transducers 270, 272, 274, 276 can also be programmed to vibrate in a manner which indicates the directionality of sound played by the DAP worn by the user. For example, different transducers positioned at different locations within the user's mouth can vibrate in a specified manner by providing sound or vibrational queues to inform the user which direction a sound arises relative to an orientation of the user. For instance, a first transducer located, e.g., on a user's left tooth, can be programmed to vibrate for sound originating from the user's left side. Similarly, a second transducer located, e.g., on a user's right tooth, can be programmed to vibrate for sound originating from the user's right side. In this manner, multi-directional sound such as THX sound can be played for the user's enjoyment. Other variations and queues may be utilized as these examples are intended to be illustrative of potential variations.
In variations where the one or more DAPs are positioned in intra-buccal locations, the DAP may be integrated directly into the electronics and/or transducer assembly, as described above. However, in additional variation, the DAP unit may be positioned at a distance from the transducer assemblies. In one example, similar to a variation shown above, DAP unit 282 may be separated from electronics and/or transducer assembly 280, as shown in
Although the variation illustrates the DAP unit 282 placed adjacent to the gingival tissue 268, unit 282 may be positioned upon another tooth or another location within the mouth. For instance,
In yet another variation for separating the DAP from the transducer assembly,
The applications of the devices and methods discussed above are not limited to the treatment of hearing loss but may include any number of further treatment applications. Moreover, such devices and methods may be applied to other treatment sites within the body. Modification of the above-described assemblies and methods for carrying out the invention, combinations between different variations as practicable, and variations of aspects of the invention that are obvious to those of skill in the art are intended to be within the scope of the claims.
