What's wrong with the customization of speaker lever?

What are the requirements of the speaker bar as an accessory of the speaker? First of all, we must know that the speaker is a hardware device used to play music, so the speaker will inevitably vibrate when the sound becomes louder, but everyone has much higher requirements for the lever of the speaker, so it is necessary to prevent shaking and expand freely. Of course, all these requirements can be achieved. For example, Dongguan Tianyu speaker tie rod customization manufacturer has been cooperating with some well-known brands, and its quality and service are guaranteed, which is also well-known in the market.
