Abstract: A speaker device comprises a vibration system, a magnetic circuit system, and an auxiliary system for accommodating and fixing the magnetic circuit system and the vibration system. The vibration system comprises a diaphragm, a centering disk and a voice coil which are joined together. The centering disk comprises a first fixing portion, a second fixing portion provided 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 sheet, the centering disk is provided with a first pad corresponding to the piezoelectric sheet, and the piezoelectric sheet is electrically connected to the first pad. Since a signal emitted by the piezoelectric sheet is mixed with an audio signal emitted by the voice coil-diaphragm, the speaker device of the present invention has improved medium-high frequency effect and acoustic performance.
