Description

Speaker

The invention provides a speaker, particularly a speaker that can achieve easy assembly, stable bonding, reduced vibration, and improved operational stability.

As for current speakers, their magnetic feedback components are usually single-magnetic structures, and the magnetic feedback components are fixedly assembled to the speaker socket of the speaker. Since there is no buffer design between the speaker socket of the single-magnetic structure and the magnetic feedback component, when the speaker is operating, the vibration of the magnetic feedback component will be directly transmitted to the speaker socket, causing the speaker to be unable to stably output sound due to vibration.

The general solution is to use an elastic body between the magnetic loop assembly and the speaker seat. The elastic body is usually installed by laser welding or gluing to weld or bond the elastic body to the magnetic loop assembly. However, the laser welding method is not only more expensive, but also requires specific welding equipment, which increases the difficulty of the operation. The gluing method will cause the bonding between the magnetic loop assembly and the speaker seat to be unstable.

Therefore, how to create a speaker that is easy to assemble and firmly combined, and can reduce the vibration of the speaker stand to improve the stability of the speaker during operation, will be what this creation wants to actively reveal.

In view of the above-mentioned shortcomings of the known technology, the creator feels that it is not perfect, so he exhausted his mind to carefully study and overcome it, and then developed a speaker, in order to achieve the effect of stably combining the magnetic feedback component and the metal elastic part through the coordination of the speaker seat assembly part, the coupling part, the first riveting area and the first corresponding riveting area, and form a buffer between the speaker seat and the magnetic feedback component through the elastic body, so as to reduce the vibration of the speaker seat when the speaker is operating, so as to improve the stability of the speaker during operation.
