    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.

    摘要: A readout apparatus and a driving method for sensor are provided. The readout apparatus includes an adjustable bias unit, a sensor unit, a signal converting unit, a checking unit and a control unit. The sensor unit senses physical energy and outputs a sensing result by using a bias voltage outputted from the adjustable bias unit. The control unit controls the adjustable bias unit according to the sensing result, so as to adjust the bias voltage. Therefore, the readout apparatus can reduce continuous power loss caused by long-term detection.
