  • Publication number: 20080056526
    Abstract: Certain embodiments of the present technology provide wireless earphone systems that include earphones configured to be supported entirely by the ear canals of the wearer and to provide stereophonic reproduction of sound to the wearer based on a two-channel stereophonic signal from a transceiver that is attachable to a device. Certain embodiments of the present technology provide wireless earphone systems that include earphones configured such that channel reception can be switched between the earphones. Certain embodiments of the present technology provide wireless earphone systems that include an earphone that includes: a housing; a ground plane comprising circuitry; and a multi-segmented antenna configured to receive a signal from a transceiver, wherein the antenna and the ground plane are disposed within the housing, wherein the antenna is substantially parallel to the ground plane, and wherein the antenna and the ground plane are separated by a distance.

  • Patent number: 7286677
    Abstract: A directional microphone assembly for a hearing aid is disclosed. The hearing aid has one or more microphone cartridge(s), and first and second sound passages. Inlets to the sound passages, or the sound passages themselves, are spaced apart such that the shortest distance between them is less than or approximately equal to the length of the microphone cartridge(s). A sound duct and at least one surface of a microphone cartridge may form each sound passage, where the sound duct is mounted with the microphone cartridge. Alternatively, each sound duct may be formed as an integral part of a microphone cartridge.

  • Publication number: 20070189569
    Abstract: Certain embodiments of the invention may be found in an insert earphone assembly. The insert earphone assembly may comprise a housing and a transducer located in the housing. The transducer may be for converting electrical signals received into sound energy. The insert earphone apparatus may further comprise an insert element. The insert element may be at, least partially integrated within the housing. The insert element may also comprise a main sound channel for communicating the sound energy from the transducer to a user. In certain embodiments, one or more of the body and the insert element may comprise one or more auxiliary ducts and one or more auxiliary volume spaces. The one or more auxiliary ducts and one or more auxiliary volume spaces may be separated by one or more auxiliary dampers.

  • Patent number: 7245728
    Abstract: A microphone assembly generally for hearing aid and communications applications is disclosed. The microphone assembly operates in both directional and non-directional or omni-directional modes. The microphone assembly has front and rear sound inlet tubes, and an actuator switch that may be moved between a first position in which the rear tube is plugged, defining the omni-directional mode, and a second position in which the rear tube is unplugged, defining the directional mode. Circuitry senses the position of the actuator switch and selects a microphone output based on the position sensed.

  • Patent number: 7162041
    Abstract: Certain embodiments of a noise canceling microphone with acoustically tuned ports are disclosed herein. In one aspect of the invention, the noise canceling microphone may comprise a housing, a transducer for converting received energy received into electrical signals, where the transducer is located in the housing, a front and rear sound pathways to a front and rear sound openings in the transducer, where the front and rear sound pathways may be located on opposite sides of the housing and may be displaced 180 degrees off a vertical axis. The noise canceling microphone may further comprising a boom for supporting the noise canceling microphone, where the boom may be deformed to place the noise canceling microphone near the mouth of the user. For example, the boom may be deformed to place the noise canceling microphone at least ten millimeters away from the edge of the mouth of the user.

  • Publication number: 20060285715
    Abstract: An insert high fidelity earphone is provided in which a hollow housing is connected to two tubes. A first tube is connected to the hollow housing on one side, and on the other side is inserted into an ear tip that ensures substantial sealing of the ear canal. A second tube is connected to hollow housing on one side and houses a cable that connects circuitry in the hollow housing to an audio source. The first tube comprises a damping assembly. The first tube comprises grooves on the inside wall that ensure that the damping assembly only fits in one orientation, which is the correct orientation. The damping assembly may be easily replaceable, without having to replace the entire earphone. The earphone may have a curved shape providing a comfortable and nearly invisible fit into the ear canal.

  • Publication number: 20060269088
    Abstract: A hearing improvement device using a multi-coil coupling system and methods for operating such a device are disclosed. An embodiment of the present invention may use an array microphone to provide highly directional reception. The received audio signal may be filtered, amplified, and converted into a magnetic field for coupling to the telecoil in a conventional hearing aid. Multiple transmit inductors may be used to effectively couple to both in-the-ear and behind-the-ear type hearing aids, and an additional embodiment is disclosed which may be used with an earphone, for users not requiring a hearing aid.

  • Publication number: 20050195996
    Abstract: A method and system for enhancing speech intelligibility using wireless communication in portable, battery-powered and entirely user-supportable devices. The devices may be talker devices and receiver devices, where the audio signals input into the talker devices may be transmitted to the receiver devices to provide better quality audio to person using the receiver devices. The receiver devices may initiate and terminate communications with the talker devices. Additionally, the receiver devices may indicate to the talker devices the gain level the talker devices need to apply to the audio signals before sending them to the receiver devices.
