Speaker repair parts rubber kit
Speaker Repair Parts Rubber Kit is a set of accessories used to repair or replace rubber components in speaker units. It usually includes the following types of rubber parts:
Suspension rubber sleeve
The suspension rubber sleeve is an important component connecting the speaker diaphragm and speaker frame. It is responsible for supporting the movement of the diaphragm and providing suspension and restoring force so that the diaphragm can work properly. Suspension rubber sleeves are usually made of soft and durable rubber material, such as rubber surround.
Dust-proof rubber cover
The dust-proof rubber cover is located between the speaker diaphragm and the speaker frame to prevent dust and protect the diaphragm. It prevents dust, debris and moisture from entering the speaker unit, keeping the speaker clean and functioning properly. Dust-proof rubber sleeves are usually made of soft rubber material and have good sealing properties.

Magnetic ring rubber sleeve
The magnetic ring rubber sleeve is located around the speaker magnetic ring to fix and protect the magnetic ring. It can reduce friction and vibration between the magnetic ring and other components, provide a stable working environment, and reduce noise and resonance.
Speaker repair parts rubber kits are usually used to repair problems such as wear, aging or cracking of rubber parts in speaker units caused by long-term use or damage. These accessories can restore your speakers to normal working order, maintaining good sound quality and performance.
