Abstract
This disclosure relates to bone conduction. One disclosed apparatus includes a support structure and a bone-conduction transducer (BCT). The support structure includes a front section and a side section. The side section includes a recessed structure and at least one member that extends from the recessed structure. The BCT includes a first portion and a second portion. The first portion is in contact with the at least one member such that at least one gap is defined between the BCT and the recessed structure. When the support structure is worn, the second portion is in contact with a wearer so as to transmit a target vibration of the second portion to a bone structure of the wearer. The at least one member is configured to transmit a vibration of the first portion of the BCT to the recessed structure.
