The invention provides a sound-generating device, which includes a vibration system and a magnetic circuit system that drives the vibration system to vibrate and produce sound. The magnetic circuit system has a magnetic gap. The diaphragm includes a ring-shaped vibrating part, an outer folded ring bent and extended from the outer periphery of the vibrating part, an inner folded ring bent and extended from the inner periphery of the vibrating part, and a first fixing part formed by extending the inner folded ring. A fixed part is abutted and fixed on the magnetic circuit system; the vibration system also includes a skeleton that suspends the voice coil in the magnetic gap. The skeleton includes a skeleton body and a skeleton connecting arm extending from the skeleton body to the direction of the voice coil. In the magnetic gap and connected with the voice coil; the connecting arm of the first fixed part and the inner ring is corresponding to the frame connecting arm, and the side close to the frame is recessed to form a groove in the direction away from the frame. Compared with the related art, the acoustic performance of the sound emitting device of the present invention is better.
Description
【Technical field】 [0001] The invention relates to the field of acoustic electricity, in particular to a sound-generating device. 【Background technique】 [0002] With the advent of the Internet age, the number of mobile terminal devices continues to rise. Among the mobile devices, the mobile phone is undoubtedly the most common and portable mobile terminal device. Sound-generating devices for playing music and other sounds are widely used in mobile terminal equipment such as mobile phones, and the vibration system in the sound-generating device is particularly important, and the entire sound-generating device vibrates and sounds through the vibration system. [0003] The related art sound-generating device includes a pot frame, a vibration system fixed on the pot frame, and a magnetic circuit system that drives the vibration system to vibrate and sound; the vibration system includes a diaphragm, inserted in the magnetic gap to drive the A voice coil vibrating the diaphragm ...
