MALLEABLE EARPIECE FOR ELECTRONIC DEVICES
An earpiece for reproducing audio has multiple drivers, including a bone conduction bass driver and an air conduction treble driver, attached to the ends of a malleable, yet stiff, tubing. The bass driver is placed behind or over the ear to provide a high quality bass output while the treble driver is placed so as to extend in proximity to the user's ear canal. The malleable, yet stiff, tubing enables a user to bend the earpiece and thereby position the earpiece comfortably and securely around the user's ear and to optimally position the drivers in the desired positions around the user's ear. The tubing also allows the earpiece, when not in use, to be reshaped for easy storage or to be worn as an accessory. The earpiece may also include one or more microphones with the treble and/or bass drivers.
This application is a continuation of and claims priority to and the benefit of U.S. application Ser. No. 15/487,699, filed Apr. 14, 2017, which claims priority to and the benefit of U.S. Provisional Application Ser. No. 62/328,918, filed on Apr. 28, 2016, and U.S. Provisional Application Ser. No. 62/353,382, filed on Jun. 22, 2016. The entire contents of each of these applications is incorporated by reference herein.
FIELD OF THE INVENTIONThe present invention generally relates to an earpiece that is configured to be multipositional behind, or above, and around a user's ear and output a high quality sound via the use of separate drivers for high and low frequencies while allowing a user to also hear ambient sounds.
BACKGROUND OF THE INVENTIONConventional headphones for outputting high quality audio often either cover the outer ear or are positioned in the ear canal. Such conventional headphones block out or dampen many ambient sounds that interfere with a user listening to the audio that is reproduced over the headphones. However, blocking or damping ambient sounds can be unsafe. For example, it is dangerous for headphones to block out sounds of oncoming traffic or sirens from an approaching ambulance. Moreover, conventional headphones that fit in the ear canal are unsanitary.
It is therefore desirable to provide one or more earpieces that allow a user to enjoy a high-quality audio reproduction while, at the same time, enabling the user to hear important ambient sounds. It is further desirable to provide earpieces that are sanitary. It is also desirable to provide earpieces that provide sound that is customizable with an application or other software, and that can also compensate for hearing loss deficiencies, in addition to providing more optimal audio.
SUMMARY OF THE INVENTIONAn earpiece with multiple speaker drivers, one for bone conduction and one for air conduction, in accordance with an embodiment of the present invention is wearable behind and around a user's ear. The earpiece is designed to be connected to an electronic device (such as a media player) so that a user can listen with the earpiece to an audio signal that is output from the electronic device. The connection between the earpiece and the electronic device may be wired or wireless.
The earpiece comprises a first assembly that is configured to be positioned behind or above a user's ear to provide bone conduction for low frequencies behind the user's ear, a second assembly that is configured to be positioned away from the first assembly when worn such as in proximity to the ear canal at a location between the user's crus (root) of the helix and the intertragal notch of the user's ear, to provide air conduction for high frequencies of an audio signal, and a malleable tubing, connecting the first and second assemblies, that allows the first and second assemblies to be adjusted to fit on an individual user's ear with the first and second assemblies in the desired positions about the ear. In embodiments, the first and/or second assemblies may be at least partially recessed within the malleable tubing.
In embodiments, the first assembly comprises: (i) a first speaker driver (or more than one speaker driver) that reproduces a first range of frequencies of a received audio signal that are below a first predetermined value using bone conduction of sound; (ii) a digital signal processor or passive crossover having an audio input for inputting the received audio signal to be reproduced by the earpiece, a first audio output to output a first part of the audio signal to the first speaker driver that is operatively connected to the digital signal processor or passive crossover, and a second audio output to output a second part of the audio signal to a second speaker driver that uses air conduction; and (iii) a power input or a power source for powering the earpiece. In embodiments, the first predetermined value may be in the range of 1 kHz to 6 kHz, in the range of 4 kHz to 5 kHz, or in the range of 1 kHz to 2 kHz, to name a few.
In embodiments of the present invention, the second assembly comprises a second speaker driver or more than one speaker drivers electrically connected to the first assembly to receive the second part of the audio signal and to reproduce a second range of frequencies that are above a second predetermined value which is the same as or greater than the first predetermined value using air conduction of sound. In alternative embodiments, the second predetermined value is below the first predetermined value such that some frequencies are reproduced by both first and second speaker drivers. The frequencies at the first predetermined value may be reproduced by either the first or second speaker drivers. In embodiments, the second speaker driver may be either unidirectional or omnidirectional.
In embodiments, a malleable tubing containing a conductive element that connects the first assembly and the second assembly is configured to be sufficiently flexible so as to be adjustable by the user to wrap around the back of the user's ear and have a sufficient stiffness in order to maintain the shape to which the user has adjusted it to hold the earpiece in place on the user's ear with the first assembly positioned behind the user's ear and the second assembly positioned away from the first assembly and in proximity to the ear canal, for example, at a location between the user's crus (root) of the helix and the intertragal notch of the user's ear. In embodiments, the malleable tubing curves around and above the user's ear and then descends to a position above the ear canal.
In embodiments, the earpiece may further comprise a microphone or microphones for a user to communicate with or via the electronic device. The microphone may be part of the first assembly or the second assembly or both, or, alternatively, either air conduction (treble) speaker driver or the bone conduction (bass) driver may become a microphone by reversing its audio to be output from the respective speaker driver to the digital signal processor (instead of audio being input from the digital signal processor to the respective speaker driver). For example, the air conduction (treble) driver may also provide the microphone capability or the bone conduction driver may provide that capability. In embodiments, microphones may be provided at both the first and second assemblies. In embodiments, a microphone may be positioned along a section of the malleable tubing away from the first and second assemblies.
In wireless embodiments, two earpieces may be provided and connected wirelessly to form a set of earpieces for the right and left ears of a user.
In wired embodiments, two earpieces may be provided and a second malleable tubing, which may be an additional segment of the first malleable tubing or a different type of malleable tubing, is connected to each of the two earpieces such that the second malleable tubing is electrically connected via a first electrical connector at a first end of the second malleable tubing to a first earpiece and a second electrical connector at a second end of the second malleable tubing to a second earpiece.
In embodiments, in addition to providing a comfortable fit, the malleable tubing is also capable of being reshaped or retractable into a non-earpiece shape for easy storage or for wearing by the user. For example, an earpiece may be reshaped as a bracelet or a pair of right and left earpieces may be reshaped into a necklace when the earpiece(s) are not in use for listening to audio or for audio communication.
In embodiments, one or more of the earpieces may be connected to eyeglasses, 3D or virtual reality (VR) glasses, virtual wearable technology, goggles, or a headset (collectively “VR glasses”) with a connector in a manner that secures the earpieces in place on the user's ear when the earpieces are worn. In embodiments, the connector to connect an earpiece to the eyeglasses is mounted to the earpiece.
In embodiments, one or more of the earpieces may be embedded within the eyeglasses.
In embodiments, at least the first speaker driver of an earpiece may be embedded within the eyeglasses. The first speaker driver (e.g., the bass driver(s)) may be embedded within a side of the eyeglasses or in a strap connected thereto to position the first speaker driver behind the user's ear to provide the first range of frequencies via bone conduction, and the second speaker driver (e.g., the treble driver(s)) to reproduce the second range of frequencies that is configured to be positioned in front of the user's ear in proximity to the ear canal. A Bone Conducting microphone (BC mic) or an Acoustic Conducting microphone (AC mic) may also be added to both assemblies.
In embodiments, at least the first speaker driver of an earpiece may be embedded into a pair of VR glasses. The first speaker driver (e.g., the bass drivers) may be embedded within a side of the VR glasses, or on a strap connected thereto to position the first speaker driver behind the user's ear to provide the first range of frequencies via bone conduction, and the second speaker driver (e.g., the treble drivers) to reproduce the second range of frequencies is configured to be positioned in front of the user's ear in proximity to the ear canal.
In certain embodiments of the earpiece, eyeglasses, or VR glasses, the second speaker driver may be configured to enable placement in the ear canal rather than outside the ear canal.
Exemplary embodiments of the present invention will be described with reference to the accompanying figures, wherein:
The present invention generally relates to an earpiece with multiple speaker drivers that provides high quality audio reproduction of audio output by an electronic device. The earpiece may be used with one or more different types of electronic devices that output audio. Examples of such electronic devices are a smartphone, a television, a stereo system, an Apple iPad or Apple TV from Apple Inc. of Cupertino, Calif., a portable audio system, a tablet computer, a laptop computer, a desktop computer, a wearable computer, a cell phone, a personal data assistant, or a specially-configured terminal, any telecommunications device, or VR glasses, to name a few. The earpiece may be used to supply audio to a single ear. In embodiments, two earpieces may be paired and used as headphones. In embodiments, there is a wired connection between the right and left earpieces, such as shown in
Earpiece 10 further includes malleable tubing 14 that connects the first and second assemblies 12 and 16. Malleable tubing 14 allows the user-adjustability of earpiece 10 such that it may be shaped, such as by bending, rotating, and/or twisting, to a position that places the speaker drivers 17, 22 (shown in
Alternatively, due to the malleable tubing 14, earpiece 10 may be adjusted and positioned differently when worn on the user's ear to provide bone conduction with first assembly 12, such as through the user's mastoid process, mandible, skull sutures, temporal bone, glabella, frontal bone, the skull in toto, zygomatic arch, or trigeminal nerve, while allowing for second assembly 16 to be adjusted to a comfortable position, such as near the user's ear canal. To enable bone conduction, earpiece 10 should be positioned with the bone conduction speaker driver positioned to emit sound directly against the user's skin.
One or more microphones may be included in earpiece 10 and output audio to DSP 20 or passive crossover (not shown). In embodiments, a microphone 18a may be included in first assembly 12 and/or a microphone 18b may be provided in second assembly 16. In addition to or in lieu of microphone 18a and/or microphone 18b, in embodiments, treble driver(s) 17 may also be a pick-up acoustic (AC) microphone and/or bass driver(s) 22 may also be a bone conducting microphone. In embodiments, a microphone may be positioned along a section of the malleable tubing away from the first and second assemblies. Where more than one microphone is provided, DSP 20 or passive crossover may be operatively controlled to select which audio input(s) will be used.
In addition, DSP 20 can communicate with software or a mobile application to customize a response to the user, and provide additional functionality. The customization process may include hearing testing to optimize the response and contour of earpiece 10 to a specific user, especially for the hearing impaired. The test procedures may incorporate head-related transfer function (HRTF) functionality for this purpose. The software or mobile application will typically reside on a cell phone, tablet or other computing device.
Because treble driver 17 may not be optimally positioned in the ear canal, it is possible that the audio from treble driver 17 is undesirably audible to individuals in the vicinity of the user. Such individuals may be disturbed by the noise or the user may wish to have privacy. A user-controlled switch (e.g., manual, electronic, or implemented in software) may therefore be optionally provided either at electronic device 28, at earpiece 10, or via remote control to turn off treble driver 17 when the user desires. Alternatively, second assembly 16 can be inserted at least partially into the user's ear canal to lessen the noise.
In the embodiment of
In the embodiment of
In embodiments as shown in
In embodiments, earpiece 10 may include one or more non-transitory memory storage devices 26 operatively connected to DSP 20 (or passive crossover) for storing and/or buffering audio to be played back or transmitted to electronic device 28. The one or more non-transitory memory storage devices may be, for example, flash memory, and/or other removable memory such as an SD card, a memory card, a flash memory card, a flash memory stick, and/or cloud memory. For example, a user may listen to songs that are downloaded via a WiFi connection.
In embodiments, malleable tubing 14 is provided to allow for a user to adjust earpiece 10 behind the back of the user's ear to properly position the bass and treble drivers 22, and 17, regardless of a user's ear size or anatomy. (In embodiments, earpieces 10 may be provided in multiple sizes, each having a different length of tubing 14). Thus, tubing 14 enables (i) a positioning of bass driver 22 that uses mastoid bone conduction behind the user's ear so that it touches the skin to vibrate against the inner bone and (ii) the desired positioning of treble driver 16 in front of the user's ear. While positioning to use the mastoid process for bone conduction is preferred, bass driver 22 may alternatively be positioned on the user's ear for bone conduction that utilizes one or more of the mandible, skull sutures, temporal bone, glabella, frontal bone, the skull in toto, zygomatic arch or trigeminal nerve of the user. Malleable tubing 14 may be formed from one or more materials, such as a metal (such as copper, aluminum, stainless steel, steel, tin, brass, zinc, or platinum, to name a few) or combination of metals (such as a combination of spring steel, copper, stainless steel and beryllium, to name a few) or from a plastic composite, that have sufficient flexibility, such that a user may adjust of the shape of tubing 14 to a particular shape, but that are sufficiently stiff or rigid such that the shape is maintained unless the user exerts a force to reshape the tubing. As another example, malleable tubing 14 may be formed from a material having elastic properties such as a thermoplastic elastomer (TPE) and more specifically an extruded TPE, which include copolymers or a physical mix of polymers (usually a plastic and a rubber) which consists of materials with both thermoplastic and elastomeric properties. Reinforcement fibers can also be used to add strength to the tubing 14. Malleable tubing 14 may also be formed from one or more other materials, such as, for example, vinyl or PVC tubing or any new alternative green technologies. In embodiments, malleable tubing 14 should have a hollow passageway between the top and bottom such that wiring/cabling, which may be insulated, can be run within tubing 14 to connect the first and second assemblies 12, 16.
When earpiece 10 is not in use, the malleability of the earpiece also enables it to be more conveniently and securely stored by the user. For example,
When the earpieces are shaped into a necklace or bracelet shape or some other shape and worn by the user, it is less likely to be misplaced or lost when not in use. Earpiece 10 can alternatively be folded so that it is not bulky to carry such as in a pocket or a purse. The optional physical connections of earpieces 10R and 10L also allow for right and left earpieces to be stored together.
In wired embodiments, where two earpieces 10R and 10L are connected with a wired connection, an additional segment of the malleable tubing, or a retractable wire or folding frame, may be connected to each of the two earpieces 10R, 10L such that the additional segment is electrically connected via a first electrical connector at a first end of the additional segment of malleable tubing (or a retractable wire or folding frame) to the first earpiece and a second electrical connector at a second end of the additional segment of malleable tubing (or a retractable wire or folding frame) to the second earpiece.
As shown in
In either the wireless embodiment or the wired embodiment, software or an application may be provided on a cell phone, tablet, smart TV, gaming console, or other computing device that would allow the user to control the AC and BC drivers to customize the sound.
Malleable tubing 14 may also be covered with designs or patterns, with a display light and/or panel (e.g., an LED display) that may be used to show device status (e.g., on/off, volume, to name a few) or may just be decorative, or with small lights such as a strip of LED lights 30 as shown, for example, in
Earpiece 10 may be used to listen to diverse types of audio, such as phone calls, music files, television, videos or any streamed audio. Additionally, earpiece 10 may be used to play relaxing, healing or meditative sounds such as solfeggio frequencies, which are believed by some, although not proven, to have healing powers, and earth sounds (e.g., sounds of rain or ocean waves, to name a few). In embodiments, solfeggio frequencies may include one or more of the following frequencies: 63 Hz, 174 Hz, 285 Hz, 396 Hz, 417 Hz, 528 Hz, 639 Hz, 741 Hz, 852 Hz, 963 Hz, and 1074 Hz. Without being bound by theory, some of the benefits of listening to the solfeggio frequencies are believed to be: 174 Hz (reduce pain), 285 Hz (influence energy fields), 396 Hz (turn grief into joy), 417 Hz (facilitate change), 528 Hz (DNA refresh and/or repair), 639 Hz (reconnecting, relationships), 741 Hz (expressions/solutions), 852 Hz (return to spiritual order), and 963 Hz (awaken perfect state). In embodiments, these frequencies are generally reproduced on bass driver 22 that uses bone conduction, rather than being reproduced with air conduction on treble driver 17. In embodiments, the relaxing, healing or meditative sounds, such as the solfeggio frequencies, may be played superimposed over other audio that is being reproduced.
In embodiments, as shown in
Connector 54 may be made, for example, of a tube-shaped material having a hollow passageway, that has elastic properties such as a thermoplastic elastomer (TPE) and more specifically an extruded TPE, which include copolymers or a physical mix of polymers (usually a plastic and a rubber) which consists of materials with both thermoplastic and elastomeric properties, to name a few. Connector 54 may alternatively be formed from one or more other materials, such as, for example, vinyl or PVC tubing.
In embodiments, at least a portion of one or more of the earpieces may be embedded within (e.g., built into) the sides of the eyeglasses (e.g., temples) or straps rather than having the one or more earpieces 10 attached to the sides of the eyeglasses as shown in
In certain embodiments of the earpiece, eyeglasses, or VR glasses described above, the second assembly may be configured for placement in the ear canal rather than outside the ear canal.
Using the above-described features, a user can enjoy the advantages of improved and customized sound delivery without being oblivious to significant ambient sounds of which a user should be aware. The user can also bend the earpiece for simplified and secure storage or for an alternative use, such as for ornamentation. The present invention also advantageously removes the earpiece from the ear canal, if desired, to reduce the chance for damaging a users hearing. In addition, other benefits may include a reduction in ear infections or ear discomfort.
Now that embodiments of the present invention have been shown and described in detail, various modifications and improvements thereon will become readily apparent to those skilled in the art. Accordingly, the exemplary embodiments of the present invention, as set forth above, are intended to be illustrative, not limiting. The spirit and scope of the present invention is to be construed broadly and not limited by the foregoing specification.
