As an information transmission tool, radio speakers often appear in our daily life. Mastering the correct use method can avoid the occurrence of many wrong operations, thereby prolonging the service life of radio speakers. About the use of broadcast horn speakers, The broadcast PA loudspeaker manufacturers remind you that you should avoid suddenly turning up the volume.

When the sound is suddenly turned on, the power amplifier will suddenly output a large amount of instantaneous energy. At this time, the speaker will have a strong vibration, which will make the coil out of the magnetic gap. When it goes back, it may fail to return to its original position due to eccentricity. The entire mechanical action is brought forward by the paper tray, deviating from the original stop position. As a result, the paper tray can no longer make a sound, but the energy continues to be transmitted to the speaker coil, and the coil leaves the magnetic gap. Because the magnetic gap is the heat dissipation environment of the coil, but the coil has left the magnetic gap, when the coil continues to receive signals from the power amplifier, the coil will soon heat up and be burned.

To sum up, broadcast horn loudspeaker manufacturers recommend that you should avoid suddenly turning on the volume or driving for a long time when using broadcast speakers. waste of money.
