Common faults:
First, easy to be affected with damp be affected with damp untight
seal: although a speaker is airtight, but if the untight seal when
washing the car into the mist or internal space have water vapor in
the air, water vapor could easily lead to contact be affected with
damp be affected with damp not work properly.
Second, the electromagnetic coil terminal poor contact: some
speakers inside the electromagnetic coil aluminum enameled wire
terminal connector is metal rivet connection, pressure to the
stable welding connection, if not end the insulating paint on the
enameled wire processing net or rivet unreliable pressure to easily
create virtual fault, lead to bad speakers work.This kind of fault
is due to the quality of the horn, which cannot be repaired, only
new parts can be replaced.
Three, contact ablation: if the horn of the speaker for a long time
contact impedance ablation, flows through the electromagnetic coil
current is abate, electromagnetic suction falling cannot attract
armature drive diaphragm normal vibration, lead to sound hoarse,
even not ring.However, when the speaker is constantly pressed, if
the instantaneous strong current can still work normally through
the impedance, it will be good or bad.
