Abstract
A speaker device is provided. The speaker device includes a frame, a vibration unit and a magnetic circuit unit. The vibration unit and the magnetic circuit unit are fixed to the frame. The magnetic circuit unit is configured to drive the vibration unit to vibrate to produce sound. The magnetic circuit unit includes a yoke. The yoke and the frame are spaced to form a leakage port. The vibration unit includes a diaphragm, a voice coil, and an elastic support assembly. The auxiliary diaphragm has one end fixed to the frame and the other end connected to the voice coil. The auxiliary diaphragm is provided with multiple vents spaced and penetrating the auxiliary diaphragm. The present disclosure can increase the circulation of gases above and below the auxiliary diaphragm, so that a side leakage effect of the speaker device is improved, thereby improving acoustic performance of the speaker device.
