Реферат: 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.
