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.

Abstract: Example embodiments may relate to methods and systems for adapting an array of piezoelectric transducers, placed on a head-mounted device (HMD), to different head sizes. For example, an HMD (e.g., a wearable computer) may include an array of transducers that are configured to operate as bone conduction transducers (BCTs), and alternatively as pressure sensors. In particular, methods and systems may be implemented to determine a respective power level for each vibration transducer in the array based at least in part on a determined mechanical load on each transducer in the array. Once the respective power level for each vibration transducer is determined, the system may cause each vibration transducer in the array to operate at the determined respective power level.
