The main function of adding a magnet to the speaker is to assist vibration and anti-interference. When our sound enters the horn, a specific change of current will generate magnetism in the coil, and a certain regular attraction or repulsion movement with the magnet This kind of vibration drives the paper cone to vibrate and amplify the sound.

Adding the magnetic ring to the speaker can not only eliminate the noise one by one, but also drive the original sound to be clearer and brighter. This is the role of the magnetic ring on the speaker. Simply put, the magnetic ring is an essential component specially designed for combating interference signals.

The magnetic ring is added to the speaker, not blindly without a target, it must be added in the right place, otherwise it will not work at all. The right place is to be as close to the interference source as possible, that is, add it where there is interference. If you don't know where the interference is, you can add it to the power cord or the circuit board in the speaker, or the output signal line. With it on the speaker, not only can the interfering signal be shut out, but also the speaker can play a beautiful and shaking singing sound.
