 Automotive electric horn sound testing, we found that the main failure is the poor speaker sound quality and volume. Adjustment, should first check whether the formation of clean contacts, the contact area of ​​not less than 80% of the original contact area and, if severely burned erosion, should be polished and cleaned or replaced.

 1 to reduce the gap between the armature and the core, can improve the tone; the other hand, increasing the gap, the lower tuning. This could be the first spin lock nut, then loosen the adjustment nut and turn the armature, can be reduced or increasing the armature and the core of the gap, the gap is usually 0.8mm. adjustment to pay attention to core must be formed, the gap around the core and the armature to be uniform, the unevenness of the maximum should not exceed 0.2mm, or will cause noise.

 2 speaker volume is too large or too small
 Speaker volume through the speaker size and the size of the coil current. Speaker volume as small, they may first loosen the lock nut, then loosen the adjustment nut, so that contact pressure due to contact pressure, which contacts contact resistance decreases, the contact closure time of growth, the current through the coil increases, the speaker volume will increase accordingly; the other hand, tighten the adjusting nut, reducing the contact pressure, the speaker volume is reduced.

 If still no results after repeated adjusted, to be investigated whether membrane rupture, damaged or bent.
