Abstract: A bone conduction microphone includes a housing having an opening, a microphone pad, an element support member, a piezoelectric element, and a drive plate. The microphone pad is formed in a bottomed tubular shape having a bottom portion disposed outward and a tubular portion with an outer circumference fixed to an inner circumference of the opening. The element support member has an outer circumference fixed to an inner circumference of the tubular portion, and a support portion projecting toward the bottom portion. The piezoelectric element is in a plate shape with a peripheral edge of one surface fixed to the support portion and picks up vibration. The drive plate has a diaphragm part fixed to an inward surface of the bottom portion, and the diaphragm part is provided at a center with a protrusion fixed to an element central portion on another surface of the piezoelectric element.

Abstract: A bone conduction speaker includes a vibration driver configured to generate mechanical vibrations and air vibrations from an audio signal, a first elastic member configured to cover a portion of the vibration driver to form a space, and convert the air vibrations emitted by the vibration driver into the space, into mechanical vibrations, a second elastic member configured to be in contact with the vibration driver, and transfer the mechanical vibrations generated by the vibration driver and the mechanical vibrations received from the first elastic member, to a user, and an adjustment screw configured to act on the first elastic member to adjust at least one of the volume of the space and the distance between vibration nodes of the first elastic member.
