In the device according to this invention, a vibrating diaphragm and a magnetic conduction plate are improved, so that the vibrating diaphragm of the speaker, under the action of magnetic force excited by different electrical signals, can convert an acoustoelectric signal into voice, can resonate together with a coil, and can be as a movable lens to constitute an optical focusing/zooming system together with lens of the camera optical system, respectively, so that the space of the mobile terminal occupied by the combination device can be saved, and the sound quality of the speaker also can be improved. |
