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.

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.

Abstract: Disclosed is a speaker device, comprising 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 piece and a voice coil which are combined together. The centering piece comprises a first fixing portion, a second fixing portion provided therein, and a connecting arm for connecting the first the second fixing portion. The second fixing portion is provided with an antenna circuit, the first fixing portion is provided with a first external bonding pad corresponding to the antenna circuit, and the antenna circuit is electrically connected to the first external pad. The speaker device of the present invention may achieve antenna functions without increasing a thickness of the speaker device, which is advantageous to a thinner design and an integrated design of the speaker device.
