[Object] To provide a bone conduction speaker unit that when incorporated in a headrest, is able to suppress an unwanted event such as sound ringing or sound leakage as much as possible, which inevitably occurs in a bone conduction speaker, and can be suitably incorporated in a headrest and a headrest incorporating the bone conduction speaker unit.[Solving Means] A bone conduction speaker unit includes a base frame 2, a low-resilience annular body 3 fixed to the top surface of the base frame 2, a damping material 4 fitted into and supported by the base frame 2, a bone conduction speaker body 5 disposed on the damping material 4 so as to be surrounded by the low-resilience annular body 3, and a contact 6 disposed on the low-resilience annular body 3 so as to cover the bone conduction speaker body 5. The contact 6 is configured to contact the vibration surface of the bone conduction speaker body 5 when the contact 5 receives a load and to leave the vibration surface of the bone conduction speaker body 5 when the load is eliminated.
