Abstract
A speaker includes a casing, a sound emitting portion, a conductive coil received in the casing, and a circuit board. The casing includes a side wall. The sound emitting portion received in the casing includes a diaphragm including a first end fixed to the casing and an opposite second end. The conductive coil includes a front end fixed to the side wall, and a rear end fixedly connected to the second end of the diaphragm. The circuit board includes an audio processing module, a charging module and a controlling module. The audio processing module is configured for receiving an audio signal and controlling the conductive coil to vibrate in response to the received audio signal. The charging module is configured for electrifying the conductive coil using alternating current. The controlling unit is configured for selectively connecting the conductive coil to the audio processing module electrically or to the charging module.
