  • Bone conduction speaker for head-mounted wearable device
    Patent number: 10582295
    Abstract: A head-mounted wearable device (HMWD) includes a bone conduction speaker (BCS) to provide audio output to a user wearing the HMWD. The BCS may be mounted within a recess of a temple of the HMWD. During wear a portion of the BCS is in physical contact with a head of the user. In one implementation, a head contact piece may be mounted to the side of the BCS that is proximate to the head. The head contact piece is contoured to maximize the contact area with the head, and may have a cross section that is approximately wedge shaped, with a thicker portion of the wedge proximate to the front of the HMWD. The BCS may include low damping elements to provide protection to the BCS from damage and improve performance, as well as high damping elements to reduce the transfer of vibrations from the BCS to the temple.

  • Dynamic range management of bone conduction speaker output
    Patent number: 10547930
    Abstract: A head-mounted wearable device (HMWD) may incorporate bone conduction speakers (BCS) to generate audio output that is perceptible to a wearer. Due to the mechanical connection between the BCS and the rest of the device, when the output amplitude of the BCSs is too great, the air-conducted audio “leaks” and may be heard by other people. This leakage may result in eavesdropping by, or generate a nuisance to, those other people. The noise level in the environment around the HMWD is determined and used to dynamically adjust the amplitude of the audio output generated by the BCS. This adjustment improves the comfort and intelligibility of the audio output to the wearer while minimizing audio leakage to the surrounding environment.
