A bone conduction device which, when particularly employed in the receiver of a bone conduction telephone, is capable of obtaining a sufficient amount of sound as to not only a bone conduction sound but also an aerial vibration sound to ensure clear reception of the sound. The bone conduction device comprises a bone conduction device unit and a case receiving the device unit therein to serve as a vibration section and is characterized in that a compliance increasing means, such as a corrugation, is disposed along the peripheral edge of the vibrating surface of the case having the bone conduction device unit fixed thereto. <IMAGE>
