MICROPHONE ARRANGED IN CAVITY FOR ENHANCED VOICE ISOLATION |
摘要 |
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. |
