The speaker 2 comprises: a diaphragm 10 supported so as to vibrate relative to the housing 4; and a driving unit 20 driving the diaphragm 10 according to an audio signal. The driving unit 20 comprises: a voice coil 21 into which the audio signal is input; and a magnetic circuit 22. The voice coil 21 vibrates in a direction which is different from the vibrating direction of the diaphragm 10, and the driving unit 20 further includes transmitting means 30 transmitting vibrations of the voice coil 21 to the diaphragm 10. <P>COPYRIGHT: (C)2012,JPO&INPIT |
