Abstract

Disclosed is a speaker device, comprising a vibration system, a magnetic circuit system, and an auxiliary system fixedly accommodating the magnetic circuit system and the vibration system. The vibration system comprises a center suspension comprising a first fixing portion, a second fixing portion within the first fixing portion, and a connecting arm connecting the first fixing portion and the second fixing portion. A central position of the second fixing portion is provided with a piezoelectric piece, the center suspension is provided with a first pad corresponding to the piezoelectric piece, and the piezoelectric piece is electrically connected to the first pad. The second fixing portion is provided with an antenna circuit. In the speaker device of the present invention, the signal emitted by the piezoelectric piece effectively increases the medium and high frequency effect and enhances the acoustic performance. The antenna circuit integrates the antenna device and the speaker device.
