Abstract

The invention provides a sound production device, and relates to the technical field of electroacoustic conversion. The sound production device comprises a basin stand, a vibration system fixed in thebasin stand and a magnetic circuit system. The vibration system comprises an upper voice diaphragm fixed on the basin stand, a voice coil connected to one side of the upper voice diaphragm, and a circuit board connected to one end, far away from the upper voice diaphragm, of the voice coil; the voice coil is provided with a voice coil lead; the circuit board comprises a bonding pad electrically connected with the voice coil lead; and the vibration system further comprises a supporting piece, the supporting piece comprises a fixing part attached to the voice coil and an extending part extending from the fixing part to the circuit board in a bent mode, the extending part is fixed to the circuit board in a stacked mode and provided with receding holes corresponding to the bonding pads, at least part of the bonding pads are exposed out of the receding holes, and the voice coil lead is electrically connected with the bonding pads through the receding holes. The problem that a vibration system swings in the prior art is solved, and meanwhile the advantage that the occupied width of a circuit board is reduced, so that the length of a magnetic circuit is increased is achieved.

Description

【Technical field】 [0001] The invention relates to the technical field of electroacoustic conversion, in particular to a sound generating device. 【Background technique】 [0002] In recent years, with the rapid development of information technology, the popularity of audio equipment has become higher and higher. People's requirements for audio equipment are not limited to video and audio playback, but also require more requirements for the reliability of audio equipment, especially in the 5G era. With the advent of mobile multimedia technology, many audio devices have multiple entertainment functions, such as video playback, digital camera, games, GPS navigation, etc. With more and more functional requirements, the integration of components in them is getting more and more integrated. The higher the price, the more stringent the quality requirements of the product. [0003] In audio equipment, the sound generating device is a commonly used electronic component, mainly used fo...
