Why do speakers need shock absorber? The vibration of the speakers in the loudspeaker unit causes the sound vibration of the box body to produce sound. The loudspeaker unit itself is a vibrating body. In addition, the sound wave impact equipment of the loudspeaker will cause vibration, even the slight vibration will damage the sound quality. The above shows that the sound equipment is actually very scared, and all kinds of vibration will affect the overall sound quality. In order to avoid the impact of vibration on sound quality, all kinds of external shock absorbers come into being. Thereby eliminating the effect of vibration on sound production.

The spike adopts anodizing process and high gloss treatment, so the appearance is exquisite and transparent. The screw rod is made of 304 stainless steel, which does not rust and fade. If it is cast iron process, it will oxidize and rust in a year and a half, which will be very ugly. Therefore, we refuse to produce low-quality products. The screw rod can be disassembled. If it does not need the kiss of the screw rod, it can be disassembled by ourselves
