Abstract

The invention relates to a novel car electronic horn. For the existing contactless car electronic horn, an electronic circuit oscillation control sound production system is used to lead the horn to sound, electronic circuit components are too many, the structure is relatively complicated, the development and material costs are high, the manufacture process is relatively complicated and both the equipment and tooling costs are also higher. The electronic horn mainly consists of a wiring terminal (15). The wiring terminal (15) is internally provided with a circuit board assembly (10). The circuit board assembly (10) is connected with a magnetic coil (7) by a lead (13), is also respectively connected with a left male tab (11) and a right male tab (14) and is wrapped with a nylon injection structure (12) at the outside. The cathode hole of the wiring terminal (15) provided with two holes is connected with a shell (6) which inside comprises static armature with a counter bore. A diaphragm (2) is connected with moving armature (1). The invention is applied to the field of car electronic horns.

Description

Technical field: [0001] The invention relates to a new type of electronic horn for vehicles Background technique: [0002] Among the existing mechanical horns with contacts, the presence or absence of current in the electromagnetic coil L1 is driven by the on-off of the contacts, thereby generating electromagnetic force to drive the diaphragm to vibrate and produce sound. Because there is a large current passing through the contact, a high induced voltage is generated when the electromagnetic coil L1 contacts and disconnects, which breaks down the air and ablates the contact, and the ablated contact is easily oxidized, thus making the contact The point contact resistance increases, making the circuit unconnected, thus making the speaker invalid. In this way, the life of the speaker is greatly reduced, which cannot meet the requirements of users. Therefore, the materials used for the metal contacts of the existing common metal contacts of the automotive mechanical horn requ...
