Abstract
Description
Technical Field
[0001] The utility model relates to a welding structure of a double-sided speaker, belonging to the technical field of speakers. Background Art
[0002] A speaker, i.e., a loudspeaker, is a structure used in many products. In order to achieve better acoustic effects, sometimes two speakers are combined to form a double-sided speaker structure. The double-sided speaker needs to be connected by wires or conductive objects. Ordinary wire connection uses a parallel welding method to weld the wires to the two speakers. However, the parallel wires are large in volume, occupying the box volume, and it is difficult to position the parallel wires, which is prone to resonance. It is necessary to add foam outside the wires, increasing the wire cost; the external wires and the parallel wire circuit need to be welded on the same solder pad, making the welding difficult. Content of the Utility Model
[0003] The main technical problem to be solved by the utility model is to provide a welding structure of a double-sided speaker, which has a small volume, a thin thickness, does not occupy the box volume, and is convenient for welding the double-sided speaker.
[0004] To solve the above technical problem, a technical solution adopted by the utility model is: to provide a welding structure of a double-sided speaker, including an upper cover and a lower cover. An upper speaker mounting groove is provided on the upper cover, an upper speaker is arranged in the upper speaker mounting groove, a lower speaker mounting groove is provided on the lower cover, a lower speaker is arranged in the lower speaker mounting groove, a welding flexible board is arranged between the upper cover and the lower cover, a conductive sheet is arranged on the welding flexible board, solder joints are respectively arranged on the upper speaker and the lower speaker, and the solder joints are welded to the conductive sheet.
[0005] Preferably, the solder joints and the conductive sheet are welded together by hot pressing.
[0006] Preferably, the welding flexible board is in an "I" shape. The welding flexible board includes two first flexible board parts, and a second flexible board part is arranged between the two first flexible board parts. The conductive sheet includes two first conductive sheets and one second conductive sheet. The two first conductive sheets are arranged diagonally. A part of the first conductive sheet is located on the first flexible board part, and another part of the first conductive sheet is located on the second flexible board part. The second conductive sheet is distributed on the two first flexible board parts and one second flexible board part.
[0007] Preferably, the solder joints on the upper speaker and the lower speaker correspond to the positions of the two first conductive sheets and one second conductive sheet, and the upper speaker and the lower speaker are welded in parallel together.
[0008] Preferably, the welding flexible board is attached to the upper cover and the lower cover by adhesive.
[0009] The beneficial effects of the present utility model are as follows: The welding structure of the double-sided speaker of the present utility model is small in volume and thin in thickness, without occupying the volume of the box body. Through thermocompression welding, manual welding only needs to weld the wires exposed outside, with high welding efficiency and convenient for welding the double-sided speaker.
