Abstract
The present disclosure provides a loudspeaker device. The loudspeaker device may include an earphone core configured to transfer an electrical signal to a vibration signal; an auxiliary function module configured to receive an auxiliary signal and perform an auxiliary function; a first flexible circuit board configured to electrically connect to an audio signal wire and an auxiliary signal wire of an external control circuit, the audio signal wire and the auxiliary signal wire being electrically connected with the earphone core and the auxiliary function module, respectively through the first flexible circuit board; and a core housing configured to accommodate the earphone core, the auxiliary function module, and the first flexible circuit board. The wiring process inside the loudspeaker device provided in the present disclosure may be simplified, thereby further reducing a volume of the loudspeaker device.
