Abstract: An electronic device may include one or more terminals configured to provide a voltage signal to an actuator. The electronic device may detect a current associated with the voltage signal provided by the terminal to the actuator. The electronic device may determine an impedance across associated with the actuator based on the voltage signal and the electrical current. The electronic device may compare the impedance to a threshold impedance to determine whether there is sufficient skin contact with the actuator. The electronic device may provide audio via cartilage conduction if there is sufficient contact based on comparing the impedance to the threshold impedance, or may output a notification to the user to adjust placement of the electronic device to improve contact.

Abstract: Embodiments relate to an audio system configured to provide enhancement of low audio frequencies. The audio system includes a tissue transducer and a speaker coupled to the tissue transducer. The tissue transducer is configured to be coupled to a tissue of a user (e.g., pinna of a user's ear). The speaker includes a diaphragm having a first surface and a second surface that is opposite the first surface. The first surface is configured to generate a first set of airborne acoustic pressure waves, and the second surface is configured to generate a backpressure. The tissue transducer is driven by the backpressure to vibrate the tissue to form a second set of acoustic pressure waves. The first set of airborne acoustic pressure waves and the second set of acoustic pressure waves together form audio content that is presented to the user.

Abstract: A system and method for removal of unwanted vibration noise are provided. The system may detect, by a microphone(s) of the system, at least one audio signal including audio content output from at least one speaker and other audio data from one or more other sources, or caused by the one or more other sources. The other audio data may include determined undesirable vibration noise causing distortion of the at least one audio signal. The system may determine, by at least one sensor of the system, a subset of the other audio data based in part on determining at least one motion of a user of the system, or motion of one or more other users. The system may remove, or reduce, the undesirable vibration noise from the at least one audio signal to enable output of sound associated with a modification of the at least one audio signal.
