Microphone Arranged in Cavity for Enhanced Voice Isolation
First Claim
1. An apparatus comprising:
- an enclosing structure having a cavity therein, wherein a first portion of the enclosing structure is formed by an elastic material, and wherein the elastic material is moveable to transfer vibration from an exterior source to gas within the cavity; and
a microphone coupled to the enclosing structure and located within the gas-filled cavity, wherein gas in the cavity separates the microphone from the elastic first portion of the enclosing structure, such that the vibration transferred from the exterior source to the gas in the cavity is detectable by the microphone.

Abstract
The present application describes bone conduction microphone (BCM) systems and applications thereof. An example apparatus includes: (a) an enclosing structure having a cavity therein, wherein a first portion of the enclosing structure is formed by an elastic material, and wherein the elastic material is moveable to transfer vibration from an exterior source to gas within the cavity; and (b) a microphone coupled to the enclosing structure and located within the gas-filled cavity, wherein gas in the cavity separates the microphone from the first portion of the enclosing structure, such that the vibration transferred from the exterior source to the gas in the cavity is detectable by the microphone.

11. A wearable-device apparatus comprising:
-
a device component of a wearable device, wherein at least portion of the device component forms an enclosing structure having a gas-fillable cavity therein, wherein at least a portion of the enclosing structure is formed by an elastic material, and wherein the elastic material is moveable to transfer vibration from an exterior source to gas within the cavity; and a microphone coupled to the enclosing structure and located within the gas-filled cavity, wherein gas in the cavity separates the microphone from the elastic first portion of the enclosing structure, such that the vibration transferred from the exterior source to the gas in the cavity is detectable by the microphone. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
