Description
Technical Field
The utility model relates to a miniature speaker especially relates to a miniature speaker of laser welding shell fragment structure.
Background
The moving-coil loudspeaker is an electroacoustic device, and the working principle is as follows: the mutual driving force between the magnetic field and the current-carrying conductor is utilized to drive the vibration of the surrounding air to generate sound waves, so that the electric signals are converted into sound signals. In order to improve the loudness of the loudspeaker, the area of the magnetic steel is increased to increase the magnetic induction strength, and the increase of the magnetic steel in the traditional in-mold injection molding elastic sheet structure cannot be realized, so that a structure of implanting the elastic sheet later, namely a laser welding elastic sheet, is needed.
Disclosure of Invention
An object of the utility model is to provide a shell fragment is implanted to back, the laser welding shell fragment structure's of the connection problem of big magnet steel speaker and complete machine signal micro loudspeaker has effectively been solved.
In order to achieve the above purpose, the technical scheme of the utility model is that: the utility model provides a laser welding shell fragment structure's miniature speaker, includes basin frame, voice coil loudspeaker voice coil, main vibrating diaphragm, pole piece, magnet steel, magnetism bowl, pad and shell fragment, magnetism bowl fixed connection on the basin frame, magnet steel fixed connection on the voice coil loudspeaker voice coil, pole piece fixed connection on the magnet steel, voice coil loudspeaker voice coil fixed connection on the basin frame, main vibrating diaphragm fixed connection on the voice coil loudspeaker voice coil, the pad is fixed in the basin frame, all be equipped with the arc wall on two sides of the one end of basin frame, laser welding has the shell fragment on the arc wall.
Preferably, the welding plate and the basin frame are integrally molded by injection.
Preferably, the elastic sheet is of an annular structure, one end of the elastic sheet is a clamping section, the other end of the elastic sheet is provided with a limiting long groove, and one end of the elastic sheet extends into the limiting long groove after being bent and forms an arc-shaped end for accommodating the arc-shaped groove.
Preferably, the elastic sheet is provided with a limiting hole, and the basin stand is provided with a limiting convex column matched with the limiting hole.
After the structure is adopted, the utility model discloses because all be equipped with the arc wall on two sides of the one end of basin frame, laser welding has the shell fragment on the arc wall. Therefore, the external elastic sheet can be well electrically connected with the external terminal, the connection problem of a large magnetic steel loudspeaker and a whole machine signal is effectively solved, the installation space is not occupied, and the structure is compact.

Detailed Description
The present invention will be described in further detail with reference to the following embodiments, which are illustrated in the accompanying drawings.
Referring to fig. 1, 2, 3, 4, a laser welding shell fragment structure's miniature speaker, including basin frame 1, voice coil loudspeaker voice coil 2, main vibrating diaphragm 3, pole piece 4, magnet steel 5, magnetism bowl 6, pad 7 and shell fragment 8, 6 fixed connection of magnetism bowl are on basin frame 1, and 5 fixed connection of magnet steel are on voice coil loudspeaker voice coil 2, and 4 fixed connection of pole piece are on magnet steel 5, and 2 fixed connection of voice coil loudspeaker voice coil are on basin frame 1, and 3 fixed connection of main vibrating diaphragm are on voice coil loudspeaker voice coil 2, and pad 7 is fixed in basin frame 1, all be equipped with arc wall 11 on two sides of the one end of basin frame 1, laser welding has shell fragment 8 on arc wall 11. The welding plate 7 and the basin frame 1 are integrated by injection molding.
Referring to fig. 4, the elastic sheet 8 is in a ring structure, one end of the elastic sheet is a clamping section 81, the other end of the elastic sheet is provided with a limiting long groove 82, and one end of the elastic sheet is bent and extends into the limiting long groove 82 to form an arc-shaped end 83 for accommodating the arc-shaped groove 11. The clamping section 81 can limit after extending into the limit long groove 82 and has certain elasticity.
Referring to fig. 4, the elastic sheet 8 is provided with a limiting hole 84, and the basin stand 1 is provided with a limiting convex column 12 matched with the limiting hole 84. The installation and the positioning are more convenient and reliable.
Referring to fig. 1 and 2, the utility model discloses a basin frame 1's one end two sides all are equipped with arc wall 11, and laser welding has shell fragment 8 on the arc wall 11, and consequently these two shell fragments 8 are external shell fragment 8, do not occupy installation space, and the structure of speaker can not change, and two external shell fragments 8 are used for external terminal electricity to be connected in addition, have effectively solved the connection problem of big magnet steel speaker and complete machine signal, do not occupy installation space moreover, compact structure.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many modifications and improvements can be made without departing from the inventive concept, and all of them belong to the protection scope of the present invention.
