摘要： The present invention provides a sound generator, includes a frame with an accommodating space, a magnetic circuit system and a vibration system. The magnetic yoke includes a bottom wall, a side wall and a supporting plate bending and extending from the side wall. The frame includes an upper surface close to the diaphragm and a lower surface provided with a fixing post. The spring includes an inner edge close to the accommodating space and an outer edge opposite to the inner edge and far away from the accommodation space. The fixing post is provided between the inner edge of the spring and the side wall. Compared to the relate art, the spring of the present invention can make more effective use of space, ensure the spring size, thus reducing the low-frequency response of the sound generator to further improve the acoustic performance.
