发明名称 BONE CONDUCTION RECEIVER
摘要 <p>Provided is a bone conduction receiver which can efficiently transmit outputted oscillation from a bone conduction speaker. A bone conduction receiver (1) is provided with a bone conduction speaker (10) for converting sound information to oscillation, and a case (2) for storing the bone conduction speaker (10). The bone conduction speaker (10) is provided with a multilayer columnar piezoelectric element (12) for generating oscillation in accordance with the sound information, and a pad (16), which protrudes from the case (2) for transmitting the oscillation generated by the multilayer columnar piezoelectric element (12) by abutting to the human head.</p>
