[Problem] The purpose of the present invention is to provide a bone conduction speaker unit which can sufficiently prevent the occurrence of sound leakage when no call is taking place. [Solution] The top of a housing (1) is covered by an elastic cover (3), and a bone conduction speaker main body (2) is incorporated inside of the housing (1) with an elastic base (4) interposed therebetween. The back surface of the bone conduction speaker main body (2) and the top surface of an elastic base (4) are partially adhered together, and/or, the elastic base (4) and the inner bottom surface of the housing (1) are partially adhered together, and when the elastic cover (3) covers the housing (1), a gap (a) is maintained between the inner top surface of the elastic cover (3) and the top surface of the bone conduction speaker main body (2), and by the elastic cover (3) being pressed during use, the inner top surface of the elastic cover (3) and the top surface of the bone conduction speaker main body (2) enter a state of contact with each other. |
