When the sound of the speaker equipment, especially the subwoofer used for playing bass, is turned up, the speaker itself will also generate strong vibrations. To reduce the adverse effects brought by the vibrations and to obtain a higher-quality bass effect, a shock-absorbing base is usually installed at the bottom. The existing shock-absorbing structure is complex, and the speaker equipment is usually very heavy and large in size. In the prior art, in order to reduce the volume of the audio equipment, control circuit boards such as batteries are installed in the available space of the base, and the base and the speaker main body are connected through a shock-absorbing structure. During operation, due to the impact and relative movement generated by the vibration, it has a great impact on the electrical contact reliability of the electrical connector, and the electrical performance and reliability of the connection are relatively low.
