Vibration system and loudspeaker

Abstract

The invention discloses a vibration system. The vibration comprises a diaphragm and a voice coil which is fixedly combined with the surface of the diaphragm. The voice coil comprises a circular voicecoil body and a lead wire led out from the same side of the voice coil body, the voice coil body comprises a led out side located at the led out position of the lead wire and a free side opposite to the led out side, the diaphragm comprises a diaphragm body part and a diaphragm reinforcing part which is combined with the surface of the diaphragm body part, and the mass of the part, corresponding to the led out side, of the diaphragm reinforcing part is lower than that of the part, corresponding to the free side, of the diaphragm reinforcing part. According to the vibration system, the mass ofthe part, corresponding to the led out side, of the diaphragm is lower than that of the part, corresponding to the free side of the voice coil, of the diaphragm, so that the quality of the lead wire of the voice coil is balanced, and a polarization phenomenon caused by unbalance mass distribution of the vibration system is relieved, so that the acoustic quality of a loudspeaker is improved.

Description

technical field [0001] The present invention relates to acoustic devices. More specifically, it relates to a vibration system and a loudspeaker applied to the vibration system. Background technique [0002] At present, the micro-speaker in the prior art includes a vibration system, a magnetic circuit system and an auxiliary system. Among them, the vibration system includes a diaphragm and a voice coil. The voice coil is attached to one side of the diaphragm. The voice coil has leads for connection to an external circuit. The magnetic circuit system includes a center magnet, a side magnet, a center washer and a side washer. Wherein, the center washer is pasted on the center magnet, the side washer is pasted on the side magnets, and a magnetic gap is formed between the center washer and the center magnet, the side washer and the side magnets. The voice coil is inserted into the magnetic gap in the magnetic circuit system. When the voice coil is fed with an alternating cu...

Problems solved by technology

Since the voice coil is provided with a dangling lead wire, the quality of the lead-out side of the voice coil is not exactly equal to that of the free side, and there is an uneven distribution, which will cause the center of mass of the vibration system to deviate from the vibration center, resulting in polarization of the vibration system, thus The distortion increases. When the polarization is serious, the voice coil and the magnetic circuit structure will rub against each other, which will seriously affect the music playback effect
