A ring which connects the coil 20c to the frame 20d and protects the diaphragm 20f and the voice coil 20c serving as a support for up and down vibration, while directly transmitting the up and down vibration to the vibration case 10. It consists of (20g).

Therefore, when an audio signal is applied to the voice coil 20c to generate an alternating rotor magnetic field, the voice coil 20c is formed by the interaction between the alternating rotor magnetic field and the direct current magnetic flux supplied from the magnet 20a and concentrated on the plate 20b. ) And the ring 20g vibrate integrally, and thus acoustic vibration waves are applied to the vibration case 10, and as a result, sound is reproduced by vibration of the vibration case 10 itself.

On the other hand, when it is impossible to transfer the audio signal from the sound source 5, the audio signal may be applied by an external audio signal supply unit (not shown). Although not shown in the drawing, the vibration case 10 is provided with an input terminal to which an external audio signal is applied. Preferably, the external audio signal supply unit is any one of an MP3 player, an audio system, and other sound related devices. As a result, when the audio signal is received from the sound source 5 or the external audio signal supply unit and transmitted to the acoustic vibrator 20, the sound is generated.
