Abstract
The utility model discloses a screw type electric speaker, which comprises a speaking cylinder, a tight loop, a cover plate of the speaking cylinder, a diaphragm component, a liner and a chassis assembly which are orderly connected. The utility model is characterized in that one side which is contacted between the tight loop and the cover plate of the speaking cylinder is extended with a reinforcing surface towards the center, and the cover plate of the speaking cylinder is compounded on the reinforcing surface of the tight loop and is combined with the reinforcing surface of the tight loop into a whole. When the screw type electric speaker of the utility model is assembled, because the cover plate of the speaking cylinder and the reinforcing surface of the tight loop are inserted and combined into the tight loop and a cover plate component of the speaking cylinder, the tight loop, the cover plate component of the speaking cylinder, the membrane component, the liner and the chassis assembly are riveted together and combined into a speaker subassembly, and the speaker subassembly and the speaking cylinder are welded together by ultrasonic to form the screw type electric speaker for a vehicle. The boundary condition of a diaphragm vibrating system is improved, and the acoustic pressure level of the screw type electric speaker and the consistency of a product are enhanced.
Description
Technical field
The utility model relates to a kind of electric automobile horn, particularly a kind of screw-type klaxon.
Background technology
Traditional screw-type klaxon structure as shown in Figure 1, comprises trumpet projector 11, trumpet projector cover plate 12, collar 13, diaphragm unit 14, liner 15 and chassis assembly 16.Prior art is when becoming electric automobile horn with above-mentioned unit construction, be collar 13, diaphragm unit 14, liner 15 and chassis assembly 16 to be riveted together be assembled into the loudspeaker sub-unit, trumpet projector 11 and the 12 usefulness supersonic weldings of trumpet projector cover plate are connected together, be combined into the trumpet projector assembly, then the loudspeaker sub-unit is pressed into have bayonet socket, around it, coat in the trumpet projector assembly of silicon rubber in advance, be combined into electric automobile horn.This structure and compound mode when being pressed into the loudspeaker sub-unit in the trumpet projector assembly, cause glue excessive easily, influence outward appearance; In addition, cooperating between loudspeaker sub-unit and the trumpet projector assembly is difficult for carrying out, and quality can not get guaranteeing, causes the boundary condition of diaphragm vibrational system relatively poor, has influenced the raising of the sound pressure level of screw-type klaxon.
Summary of the invention
The utility model is in order to solve the problems referred to above that prior art exists, a kind of screw-type klaxon of new structure combination to be provided.This screw-type klaxon simple and convenient assembly, quality assurance, and can make the raising of the sound pressure level of screw-type klaxon.
The technical solution adopted in the utility model is: a kind of screw-type klaxon, comprise trumpet projector, trumpet projector cover plate, collar, diaphragm unit, liner and chassis assembly that order links to each other, be characterized in: a reinforcement face extends in the side direction central authorities that described collar contacts with the trumpet projector cover plate, described trumpet projector cover plate is compounded on the reinforcement face of collar, and is combined as a whole with the reinforcement face of collar.
Above-mentioned screw-type klaxon, wherein: the reinforcement face of described trumpet projector cover plate is provided with a plurality of through holes, when described trumpet projector cover plate is close on the reinforcement face of collar, be embedded in this through hole with the joint portion branch of through hole on the reinforcement face of this collar, the reinforcement face of trumpet projector cover plate and collar is combined as a whole.
Above-mentioned screw-type klaxon, wherein: the reinforcement face of described trumpet projector cover plate is provided with a plurality of elongate slots, when described trumpet projector cover plate is close on the reinforcement face of collar, the part that combines with elongate slots on the reinforcement face of this collar can be embedded in this elongate slots, and the reinforcement face of trumpet projector cover plate and collar is combined as a whole.
Above-mentioned screw-type klaxon, wherein: the central authorities that face is strengthened in described collar are provided with a macropore.
The utility model screw-type klaxon is combined into collar and trumpet projector cover plate assembly through after the particular design as inserts and trumpet projector cover plate with traditional collar, during assembling, collar and trumpet projector cover plate assembly and diaphragm unit, liner and chassis assembly be riveted together is combined into the loudspeaker sub-unit, again with loudspeaker sub-unit and trumpet projector with the supersonic welding formed automobile screw-type klaxon that is connected together.Improve the boundary condition of diaphragm vibrational system, improved the sound pressure level and the consistency of product of screw-type klaxon greatly.
