[0029] Such as Figures 1 to 6As shown in the figure, a horn that is convenient for welding includes a bracket 10. The bracket 10 is provided with a magnet 20, a washer 30, a voice coil 40, a diaphragm 50 and a cover plate 60. The cover plate 60 covers the magnet 20, the washer 30, the voice coil 40 and the diaphragm 50 on the bracket 10. Specifically, a cavity is opened in the middle of the bracket 10. The magnet 20, the washer 30 and the voice coil 40 are placed in the cavity. A square hole is opened in the middle of the cover plate 60. The periphery of the cover plate 60 presses the diaphragm 50 on the bracket 10. The square hole provides a space for the diaphragm 50 to vibrate. Positioning posts 104 are respectively arranged at the four corners of the bracket 10. Positioning holes are opened at the four corners of the cover plate 60. The cover plate 60 is fixed on the bracket 10 through the cooperation of the positioning posts 104 and the positioning holes, playing a role of positioning and fixing.

[0030] Furthermore, the bottom of the bracket 10 includes a bottom plate that is detachable. The four sides of the bottom plate are bent in the same direction to form clamping plates. The four clamping plates enclose a cavity for placing the magnet 20, the washer 30 and the voice coil 40, playing a role of positioning.

[0031] As Figures 1 to 6 shown in the figure, two welding parts are embedded in the bracket 10. The welding parts include an inner welding piece 101 and an outer welding piece 102. The inner welding piece 101 and the outer welding piece 102 are connected. The inner welding piece 101 is placed in the cavity of the bracket 10, and the outer welding piece 102 is placed outside the bracket 10. The lead of the voice coil 40 is connected to the inner welding piece 101. When the horn is connected to an external power supply, it is welded to the outer welding piece 102 through an electric wire. The outer welding piece 102 is connected to the inner welding piece 101, and the inner welding piece 101 is connected to the lead of the voice coil 40, realizing the electrical connection of the voice coil 40. It avoids realizing the electrical connection of the voice coil 40 by welding on the pins. The area of the outer welding piece 102 is large and flat, which is easy for the operator to operate during welding. The contact area is large, and problems such as insecure welding and poor contact are not likely to occur at the welding place, and the welding efficiency is improved.

[0032] As Figures 1 to 6 shown in the figure, several sound outlet holes 103 are further opened in the bracket 10. In this embodiment, there are 4 sound outlet holes 103, with two arranged on each side, for the sound of the horn to be emitted.

[0033] In addition, the welding parts and the bracket 10 are integrally formed, improving the stability of the installation of the welding pieces and the bracket 10, and at the same time improving the production efficiency.

[0034] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
