Abstract

The present disclosure relates to a speaker device. The speaker device may include an ear hook, a core housing for accommodating an earphone core, and a circuit housing for accommodating a control circuit or a battery. The ear hook may include a first plug end and a second plug end. The ear hook may be surrounded by a protective sleeve which may be made of an elastic waterproof material. The ear hook may be elastic, and a position of the core housing relative to the ear hook may be changed according to an elastic deformation of the ear hook, thereby the core housing may fit a user in front of or behind an ear of the user. The circuit housing may be fixed to the second plug end. The control circuit or the battery may drive the earphone core to vibrate to generate a sound.
