Disclosed is a speaker device, comprising a vibration system, a magnetic circuit system, and an auxiliary system accommodating and fixing the magnetic circuit system and the vibration system. The vibration system comprises a diaphragm, a centering support piece and a voice coil which are combined together. The centering support piece comprises a first fixing portion, a second fixing portion arranged within the first fixing portion, and connecting arms 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 centering support piece is provided with first solder pads in correspondence with the piezoelectric piece, and the piezoelectric piece is electrically connected to the first solder pads. In the speaker device of the present invention, a signal emitted by the piezoelectric piece is mixed with an audio signal emitted by the voice coil and the diaphragm, a medium and high frequency effect of the speaker device is effectively improved, and the acoustic performance of the speaker device is improved. Therefore, the speaker device of the present invention has the advantage of good acoustic performance. |
