When sound signals are input to a vibration driver through signal wires, the vibration driver converts the sound signals into mechanical vibrations. A second elastic member transmits the mechanical vibrations of the vibration driver to a user. On the other hand, air vibrations are generated by the vibration driver in a space formed by the vibration driver and a first elastic member. The air vibrations are converted into mechanical vibrations by the first elastic member, and are transmitted to the second elastic member. The second elastic member also transmits the mechanical vibrations transmitted from the first elastic member, to the user.
