Abstract: The present disclosure relates to managing audio signals within a user's perceptible audio environment or soundstage. That is, a computing device may provide audio signals with a particular apparent source location within a user's soundstage. Initially, a first audio signal may be spatially processed so as to be perceivable in a first soundstage zone. In response to determining a high priority notification, the apparent source location of the first audio signal may be moved to a second soundstage zone and an audio signal associated with the notification may be spatially processed so as to be perceivable in the first soundstage zone. In response to determining user speech, the apparent source location of the first audio signal may be moved to a different soundstage zone.

Abstract: The present application describes signal enhancements to reduce bone conduction sensations of a wearable computing device and applications thereof. An example apparatus includes a wearable computing device comprising a bone conduction transducer (BCT) configured to receive and be driven by an audio signal, a processor, and a data storage comprising instructions executable by the processor to: (1) determine an input gain level of the audio signal at a frequency range; (2) compare the determined input gain level at the frequency range to a threshold gain level at the frequency range; (3) based on the comparison, apply a multi-band compressor (MBC) configured to process the audio signal to reduce gain in at least a portion of a mid-band frequency range of the audio signal; and (4) drive the BCT with the processed audio signal.

Abstract: A bone conduction transducer includes a yoke having a pair of arms, a layer of high permeability steel on a surface of the yoke between the arms, a metal coil, a metallic post that extends into a center portion of the metal coil, a diaphragm, an anvil attached to a surface of the diaphragm, a pair of permanent magnets attached to an opposite surface of the diaphragm, and a pair of springs. A first end of each spring is attached to a respective one of the arms of the yoke, and a second end of each spring is coupled to the diaphragm. The diaphragm is configured to vibrate in response to a signal supplied to the metal coil. The diaphragm could be formed from a from a permanent magnet.

Abstract: An example method may be performed by a wearable computing device (WCD) that includes a bone conduction transducer (BCT). The method includes providing, to the BCT, an input signal that represents audio content. The method further includes sensing a time-varying voltage of the input signal and a time-varying current of the input signal. The method further includes determining an operating mode based on the time-varying voltage and the time-varying current. The method further includes processing the audio content according to the determined operating mode and using the processed audio content to continue providing the input signal to the BCT.

Abstract: Embodiments disclosed in the present disclosure relate to vibration transducers. Such a transducer includes an electromagnet having a conductive coil. The conductive coil is configured to be driven by an electrical input signal to generate magnetic fields. The transducer further includes a magnetic diaphragm that is configured to mechanically vibrate in response to the generated magnetic fields. Additionally, the transducer includes a pair of cantilevered arms formed from damping steel. The cantilevered arms couple the magnetic diaphragm to a frame. The magnetic diaphragm vibrates with respect to the frame when the electromagnet is driven by the electrical input signal. Additionally, the pair of flexible support arms are connected to opposing sides of the magnetic diaphragm.
