摘要：
A driving interface device adaptive to a flat speaker is introduced herein. The driving interface device is coupled with an external sound source for receiving sound signals, and boosts voltage levels of the sound signals to drive the thin flat speaker without using an external power source. In one embodiment, an impedance component is provided in the driving interface device for coupling to the external sound source, so as to drive the flat speaker.
