Claims

[Scope of utility model registration request]

(1) A support member, an electroacoustic transducer whose one end is supported by the support member, a contact portion fixed to the electroacoustic transducer, and at least the electroacoustic transducer support portion of the support member and the electroacoustic transducer. A cylindrical damper member molded to cover the element; a prismatic damper member having a conical shape or a polygon with a cross section close to a circle and having a large hysteresis; . A direct pickup type bone conduction microphone, wherein the contact portion is embedded near the surface of the damper member or protrudes from the surface.

(2) The utility model registration claim is characterized in that the electroacoustic transducer element extends at a predetermined angle in the axial direction of the damper member, and a contact portion is provided at the free end of the electroacoustic transducer element. A direct pickup bone conduction microphone according to scope 1.

(3) The reinforcing member, one end of which is attached to the support member, extends parallel to S in the axial direction of the damper member and is embedded in the tamper member. A direct pickup type bone conduction microphone according to claim 1 or 6 or 2 of the utility model registration claim.

(4) The direct pickup type bone conduction microphone according to claim 1 or 2, wherein the damper member except for the vicinity of the contact portion is covered with an ear tip.
