摘要： Provided is a sounding device, including frame and vibration system and magnetic circuit unit fixed to the frame. The vibration system includes diaphragm, voice coil driving the diaphragm to vibrate and sound, holder fixed to diaphragm, and auxiliary diaphragm spaced from diaphragm. The holder includes holder main body, first connection portion formed from holder main body to magnetic circuit unit and second connection portion spaced from first connection portion. The voice coil is fixed to second connection portion. One end of the auxiliary diaphragm is fixed to frame. One end of first connection portion away from holder main body bends and extends away from second connection portion to form flange. One end of auxiliary diaphragm away from frame is fixed to flange. The sounding device may reduce accuracy deviation and hidden dangers of gluing failure caused by rear assembling of the auxiliary diaphragm.

摘要： Provided is a speaker, including a frame; a vibration unit fixed to the frame; and a magnetic circuit unit driving the vibration unit to vibrate and produce sound. The vibration unit includes a diaphragm and a voice coil; the diaphragm includes a first suspension, a second suspension and a vibrating portion; the magnetic circuit unit is provided with a magnetic gap, and the voice coil is inserted in the magnetic gap; the magnetic circuit unit includes a yoke; and the yoke and the diaphragm are arranged at two opposite sides of the frame; and the vibration unit further includes a fixing ring connected to the magnetic circuit unit; the second suspension surrounds the fixing ring; and an inner peripheral side of the second suspension is fixed to an end of the fixing ring away from the yoke. With this structure, the acoustic performance of the speaker can be improved.
