Description

Technical Field

[0001] The invention relates to the field of speaker debugging, and more specifically to a silent debugging device for automobile speakers. Background Art

[0002] The horn is an audio signal device for cars and motorcycles. During the driving process of cars and motorcycles, the driver sends out necessary audio signals according to needs and regulations to warn pedestrians and attract the attention of other vehicles to ensure traffic safety. It is also used to urge people to drive and transmit signals. Existing horns for cars and motorcycles make sounds by the vibration of metal diaphragms. It is composed of iron core, magnetic coil, contact, armature, diaphragm, etc. When the driver presses the horn switch, the current passes through the coil through the contact, and the coil generates magnetic force to suck down the armature, forcing the diaphragm to move. The armature moves to disconnect the contact, the current is interrupted, the magnetic force of the coil disappears, and the diaphragm returns to its original position together with the armature under the action of its own elasticity and spring sheet. The contact closure circuit is connected again, and the current flows through the coil through the contact to generate magnetic force. Repeat the above actions, and the diaphragm vibrates continuously in this repeated cycle, thereby making sounds. The debugging of the horn generally includes two items: iron core air gap adjustment and contact pre-pressure adjustment. The former adjusts the tone of the horn, and the latter adjusts the volume of the horn.
