Description
Technical Field
The present utility model relates to the field of speaker technologies, and in particular, to a speaker vibration system and a speaker.
Background
At present, along with the improvement of the living standard of people, the requirements on an audio-visual system are also higher and higher. Vibration systems are important components of loudspeakers, including diaphragms, voice coils, etc. At present, the bonding structure of the vibrating diaphragm and the voice coil makes the acting force of the voice coil not act on the vibrating diaphragm completely, so that energy loss is caused, high-frequency attenuation is early, the frequency range is unqualified, the hearing is reduced, and the performance of the loudspeaker is influenced. As shown in fig. 1, the weak position of the diaphragm 01 is a concave position on the diaphragm, and due to the limitation of the structural shape of the diaphragm, the acting force of the voice coil 02 cannot be completely transmitted to the weak position of the diaphragm 01 after the voice coil 02 is adhered to the diaphragm 01, so that energy loss is generated, and high-frequency performance is affected. Therefore, a new type of loudspeaker vibration system is needed.
Disclosure of Invention
