Patent attributes
A head-mounted wearable device (HMWD) uses temples as housing for a transducer, maximizing the available space within the temples for other components, such as a battery. The exteriors of the temples act as housings so that separate transducer housings do not consume space within the temples. The temples may include openings that direct emitted sound toward the ear of a user of the HMWD. Sound generated by the transducer exits the openings and provides audio to the user's ear having a suitable volume. Each temple may include two microphones to facilitate use of a beamforming algorithm. When voice input is received, the HMWD may determine a particular set of microphones for use based on a charge level of power storage devices in each temple, a noise level associated with the microphones, or other factors.
