Abstract
The present disclosure discloses a loudspeaker apparatus. The loudspeaker apparatus may include an ear hook, a core housing, and a circuit housing. The ear hook may include a first plug end and a second plug end. The ear hook may be surrounded by a protective sleeve. The protective sleeve may be made of an elastic waterproof material. The core housing may be used for accommodating an earphone core. The core housing may be fixed to the first plug end and elastically abutted against the protective sleeve. The circuit housing may be used for accommodating a control circuit or a battery. The circuit housing may be fixed to the second plug end. The control circuit or the battery may drive the earphone core to vibrate. The vibration of the earphone core may generate a driving force to drive a housing panel of the core housing to vibrate. The driving force may be not parallel to a normal line of the housing panel. In the present disclosure, the core housing may elastically abut against the protective sleeve surrounding the ear hook to improve the overall waterproof effect of the loudspeaker apparatus and simplify the manufacturing and assemble process of the loudspeaker apparatus.
