US Patent:

6422991, Jul 23, 2002

Filed:

Jul 11, 2000

Appl. No.:

09/613901

Inventors:

Eric M. Jaeger - Redwood City CA

Assignee:

Symphonix Devices, Inc. - San Jose CA

International Classification:

H04R 2500

US Classification:

600 25

Abstract:

This invention relates to an implantable microphone device. The implantable microphone device typically comprises a housing defining an internal chamber. It typically further comprises a microphone arrangement on the housing, the microphone arrangement having a first cavity, a second cavity, and a membrane separating the first and second cavities such that vibrations entering the first cavity causes the membrane to vibrate, and to transmit vibrations into the second cavity. The implantable microphone device further comprises at least one vent extending between the second cavity of the microphone arrangement and the internal chamber of the housing so as to permit the vibrations to pass from the second cavity of the microphone arrangement into the internal chamber of the housing.

International Classification:

A61F 1743

US Classification:

600 25, 29605

Abstract:

A dual coil floating mass transducer for assisting a persons hearing is provided. Inertial vibration of the housing of the floating mass transducer produces vibrations in the inner ear. A magnet is disposed within the housing biased by silicone springs so that friction is reduced between the magnet and the interior surface of the housing. Two coils reside within grooves in the exterior of the housing which cause the magnet to vibrate when an electrical signal is applied to the coils.

International Classification:

H04R 2500

US Classification:

600 25, 381326, 607 57

Abstract:

Implantable microphone devices that may be utilized in hearing systems are provided. An implantable microphone device allows the implantable microphones frequency response and sensitivity to be selected. A microphone device with an increased membrane flexibility and a decreased acoustic compliance of the sealed cavity. Vibrations of a membrane are transmitted through a primary air cavity and through an aperture of a microphone. Keeping a flexible membrane and decreasing the sealed air cavity compliance are the preferred way to simultaneously increase overall sensitivity of the device, and move the resonance peak to higher frequencies.
