Problem: To provide a bone conduction speaker unit which can sufficiently prevent generation of sound leakage at the time of non-calling. Solution: A bone conduction speaker unit, including a bone conduction speaker main body 2, being incorporated in a housing 1 with an elastic base being interposed, an elastic cover 3 being mounted on a top face of the housing. Bonding between a rear face of the bone conduction speaker main body 2 and a top face of the elastic base 4, and/or bonding between the elastic base 4 and an inner bottom face of the housing 1 are partially made; upon the elastic cover 3 having been mounted on the housing 1, a gap 'a' is held between an internal top face of the elastic cover 3 and a top face of the bone conduction speaker main body 2; and with the elastic cover 3 being pressed in use, the internal top face thereof is abutted against the top face of the bone conduction speaker main body 2. |
