Three reasons for the horn's failure

 What if the megaphone fails? Here are some reasons why the horn is failing.

 1、Long-term overload drive the horn, the horn will be overheated and burnthethet, because the temperature of the coil increased, so that some parts of the structure to melt, crack or burn, the normal use of the coil temperature there is 180 degrees Celsius, abnormal use can be imagined!

 2、Mechanical failure, overload of the drive horn makes the tray move out of range and separate from the coil, or the coil and coil seat separation, the paper tray fold ingest or horn support ring is torn, in order to take advantage of the situation once it occurs, the horn can fail. When the folding edge or support ring is torn, the coils will rub with them, because the tray components can no longer be properly suspended in the center, small cracks may not feel at first, but after a period of time, when the cracks become large, the horn will follow the break.

 3、The failure of the horn may also be a combination of the above two ways, such as the amplifier suddenly output a large instant energy, this energy can be the sound suddenly open, the horn will have a strong vibration, so that the coil out of the magnetic gap, when it goes back may eccentric error can not return to the original position, This will make the entire mechanical action by the paper tray to the front, deviate from the original stop position, the result of the paper tray has been unable to make a sound, but the energy also continues to transmit the horn on the coil, the coil double left the magnetic gap, because the magnetic gap is the best cooling environment of the coil, but the coil has left the magnetic gap,

Then when the coil continues to receive signals from the amplifier, the coil will soon heat up and burn the coil.
