Automobile tweeter

Abstract

The purpose of the present invention is to solve the problem that the existing speakers are inconvenient to enlarge the volume. A car tweeter is disclosed, which includes a two-way speaker. A fixed ring is fixedly installed in the middle of the surface of the two-way speaker. The wire corresponding to the two-way horn, the support rod is fixedly installed on the upper side of the fixed ring, the fan is fixedly installed on the upper end of the support rod, the air guide pipe is fixedly installed on both sides of the fan, and the surface of the fixed ring is symmetrically installed with A connecting rod, a connecting block is fixedly installed on the outer end of the connecting rod, a collar is fixedly installed on the outer side of the connecting block, an air guide ring is fixedly installed on the surface of the collar, and through holes are evenly opened on the surface of the air guide ring. The present invention is provided with a fan to facilitate blowing of the wind guide ring, so that the wind can be guided through the through holes on the wind guide ring, so that the sound can be spread outwards, and the transmission range can be expanded, thereby increasing the volume of the speaker.

Description

technical field [0001] The invention relates to the field of speakers, in particular to an automobile tweeter. Background technique [0002] The car electric horn is made by the vibration of the metal diaphragm to make sound. The car electric horn is composed of iron core, magnetic coil, contact, armature, diaphragm and so on. When the driver presses the horn switch, the current passes through the coil through the contact, and the coil generates magnetic force to attract the armature, forcing the diaphragm to move, and the armature moves to disconnect the contact, the current is interrupted, and the magnetic force of the coil disappears. Under the action, it will return to the original position together with the armature, and the contact closure circuit will be connected again, and the current will flow through the coil through the contact to generate magnetic force, and the above actions will be repeated. The diaphragm vibrates continuously in such a repeated cycle, there...

Problems solved by technology

[0003] However, the existing car horns are generally single-item, and the range of transmission is small, so it is inconvenient to expand the range of sound transmission. When driving on a noisy street, the sound that the traditional horn sends is not easy to remind the vehicle. The blocking of the horn will affect the transmission of the sound of the horn, and the horn is transmitted through the air medium. The existing device is inconvenient to spread the sound outward, and the existing tweeter needs to replace the internal structure of the ordinary horn to form a tweeter. , more troublesome, while increasing the manufacturing cost, and some devices use a one-way horn to whistle when in use, which reduces the range of sound transmission, thereby affecting the reminder of the vehicle and causing inconvenience to the user
