Abstract: A bone conduction microphone of the present disclosure includes: a vibration sensor that comes into contact with a nose of a living body from outside the living body and converts vibration into an electric signal; a head-worn part that is worn on a head of the living body; and a sensor support that hangs from the head-worn part and supports the vibration sensor toward the nose.

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.
