Description

Technical Field

[0001] The utility model relates to the technical field of loudspeaker equipment, in particular to a loudspeaker which is easy to weld. Background Technique

[0002] A loudspeaker, also known as a speaker, the working principle of its relatively common electrodynamic loudspeaker is based on Faraday's law. When a current-carrying conductor passes through a magnetic field, it will be subjected to an electromotive force, and its direction conforms to Fleming's left-hand rule. The force is perpendicular to the current and magnetic field directions, and the magnitude of the force is proportional to the current, wire length, and magnetic flux density. When an alternating audio current is input to the voice coil, the voice coil is subjected to an alternating driving force to generate an alternating motion, driving the paper cone to vibrate and repeatedly pushing the air to produce sound.

[0003] At present, in the manufacturing process of existing loudspeakers, welding processes are often required to connect various components, such as wires and PCB boards, voice coils and brackets, etc. During operation, the wires need to be manually placed at the positions to be welded. However, during the welding process, the wires will inevitably move to a certain extent, resulting in defective products, undoubtedly increasing the production difficulty and cost and causing product quality problems. Content of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide a loudspeaker which is easy to weld to solve the technical problems raised in the above background technique.

A PCB board is installed in the mounting frame through the outer frame, and a front plate is provided on one side of the outer frame. A front cover plate is provided on an outer side of the front plate;

[0006] A limiting mechanism is provided on one side of the PCB board. The limiting mechanism includes a limiting frame and a limiting pad. The limiting pad is pasted on an inner surface of the limiting frame. An anti-offset mechanism extending to the outside is provided inside the limiting frame. The anti-offset mechanism includes a movable groove, a telescopic spring, an anti-offset groove, and a push block. A movable groove is opened on one side of the limiting frame, and an anti-offset plate is movably connected inside the movable groove.

[0007] Preferably, both the limiting frame and the limiting pad are provided in an arc structure, and the limiting pad is made of elastic rubber material.

[0008] Preferably, a telescopic spring is connected between the anti-offset plate and the movable groove, and the anti-offset plate and the movable groove form an elastic structure through the telescopic spring.

[0009] Preferably, a bottom end of one side of the limit frame is provided with an anti-offset groove, and the anti-offset plate and the limit frame form a snap-fit structure through the anti-offset groove.

[0010] Preferably, a push block is arranged at a bottom end of one side of the anti-offset plate.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0021] Next, the embodiments of the present invention will be described according to the overall structure of the present invention.

[0022] A horn that is easy to weld, as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, includes a horn body 1 and a wire 5, and the horn body 1 includes a rear cover plate 101, a mounting frame 102 and an outer frame 103. An inner side of the rear cover plate 101 is provided with the mounting frame 102. A PCB board 104 is installed in the mounting frame 102 through the outer frame 103. One side of the outer frame 103 is provided with a front plate 105. An outer side of the front plate 105 is provided with a front cover plate 106. One side of the rear cover plate 101 is installed with a hanging bracket 2. There are two hanging brackets 2 symmetrically arranged about the central axis of the rear cover plate 101;

[0023] Referring to Figure 1 and Figure 4 it can be seen that the horn body 1 can be easily hung at a required position through the hanging bracket 2 to increase the convenience during use.

[0024] Referring to Figure 1 、 Figure 2 and Figure 3 it can be seen that a limiting mechanism 3 is provided on one side of the PCB board 104. The limiting mechanism 3 includes a limiting frame 301 and a limiting pad 302. The limiting pad 302 is adhered to the inner surface of the limiting frame 301. Both the limiting frame 301 and the limiting pad 302 are provided with an arc-shaped structure. The limiting pad 302 is made of elastic rubber material;

[0025] Referring to Figure 2 and Figure 3It can be seen that since the limiting frame 301 is set as an arc structure and the limiting pad 302 is made of elastic rubber material, when welding operation is required, the wire 5 can be aligned with the limiting frame 301 and pushed forcefully, so that the wire 5 is stuck inside the limiting pad 302, thus realizing the limitation of the position of the wire 5.

[0026] Refer to Figure 2 and Figure 3 It can be seen that an anti-offset mechanism 4 extending to the outside is arranged inside the limiting frame 301. The anti-offset mechanism 4 includes a movable groove 401, a telescopic spring 402, an anti-offset groove 404 and a push block 405. A movable groove 401 is formed on one side of the limiting frame 301. An anti-offset plate 403 is movably connected inside the movable groove 401. A telescopic spring 402 is connected between the anti-offset plate 403 and the movable groove 401. The anti-offset plate 403 and the movable groove 401 form an elastic structure through the telescopic spring 402. An anti-offset groove 404 is formed at the bottom end of one side of the limiting frame 301. The anti-offset plate 403 and the limiting frame 301 form a clamping structure through the anti-offset groove 404. A push block 405 is arranged at the bottom end of one side of the anti-offset plate 403;

[0027] Refer to Figure 1 、 Figure 2 and Figure 3 It can be seen that since the anti-offset plate 403 and the movable groove 401 are elastically connected through the telescopic spring 402, after the wire 5 is limited, the push block 405 can be released, so that the anti-offset plate 403 is reset under the action of the telescopic spring 402 and is clamped with the anti-offset groove 404, so that the anti-offset operation of the wire 5 can be realized through the anti-offset plate 403, and then the stable welding operation of the wire 5 and the PCB board 104 can be facilitated, the convenience of use is increased, and at the same time, the cooperation of the limiting frame 301 and the anti-offset plate 403 can prevent the solder joints from loosening and being damaged due to the movement of the rear-end wire 5 after welding, thus prolonging the service life of the speaker.

[0028] Refer to Figure 2 and Figure 3 It can be seen that a limiting groove 7 is formed inside the anti-offset plate 403, and a limiting rod 6 which forms a sliding structure with the limiting groove 7 is arranged inside the movable groove 401, which can play a role in supporting and limiting the anti-offset plate 403, so that the stability of the anti-offset plate 403 during the sliding process can be increased.

[0029] The working principle of the present utility model is as follows: When using the easily weldable speaker, the anti-offset plate 403 can be slid in the movable slot 401 by pushing the push block 405, causing the telescopic spring 402 to be compressed. At this time, the wire 5 can be aligned with the limit frame 301 and pushed forcefully, so that the wire 5 is snapped into the inner side of the limit pad 302, thereby realizing the limitation of the position of the wire 5. At this time, the push block 405 can be released, so that the anti-offset plate 403 will reset under the action of the telescopic spring 402 and be clamped with the anti-offset slot 404, so that the anti-offset operation of the wire 5 can be achieved through the anti-offset plate 403. Furthermore, it is convenient to perform a stable welding operation between the wire 5 and the PCB board 104. At this time, the assembly of the speaker main body 1 can be carried out. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
