The present invention addresses the problem of providing a bone conduction speaker unit and a headrest incorporating the bone conduction speaker unit, the bone conduction speaker unit being suitable for being incorporated into a headrest, and being capable of minimizing the occurrence of bad phenomena such as sound, sound leakage and the like, which must occur in the bone conduction speaker, when the bone conduction speaker unit is incorporated into the headrest for use. A low-resilience annular body (3) fixed to the upper surface of a base frame (2), a vibration-damping material (4) fitted into the base frame (2), a bone-conduction speaker main body (5) disposed on the vibration-damping material (4) in a state surrounded by the low-resilience annular body (3), and a low-resilience annular body (3) disposed so as to cover the bone-conduction speaker main body (5) and a contact (6) on the bone conduction speaker body (5), the contact (6) being in contact with the vibration surface of the bone conduction speaker body (5) when the load is applied, and being separated from the vibration surface of the bone conduction speaker body (5) when the load is not applied.

    本发明的课题在于提供骨传导扬声器单元和内置有该骨传导扬声器单元的头枕,该骨传导扬声器单元在内置于头枕而使用的情况下,能够极力抑制在骨传导扬声器中必然产生的鸣音、漏音等不好的现象的产生,作为头枕内置用是合适的。设为如下的构成:由基架(2)、固定于基架(2)的上表面的低回弹性环状体(3)、嵌入至基架(2)内的减振材料(4)、以被低回弹性环状体(3)包围的状态配置于减振材料(4)上的骨传导扬声器主体(5)以及以覆盖骨传导扬声器主体(5)的方式配置于低回弹性环状体(3)上的接触件(6)构成,接触件(6)在负荷时抵接于骨传导扬声器主体(5)的振动面,在无负荷时从骨传导扬声器主体(5)的振动面离开。
