Description

Technical Field

[0001] The utility model belongs to the technical field of speaker coil assembly, and specifically relates to a speaker assembly positioning coil mold. Background Art

[0002] The speaker coil is usually mounted on the pole or diaphragm of the speaker driver. In many speaker drivers, the coil is usually mounted on the pole. The pole is an electromagnet that produces a stable magnetic field. The coil is wound near the pole. When current passes through the coil, it interacts with the magnetic field, causing the speaker driver to produce sound.

[0003] Generally, when assembling or replacing the coil of a larger speaker, the prepared coil needs to be slowly inserted into the outside of the magnetic pole. Since the gap between the magnetic pole and the diaphragm is small and the diameter of the copper wire on the coil is thin, if the coil tilts during the insertion process, the copper wire is easily torn off, affecting the transmission of current. Secondly, a lot of dust is easily adhered to the magnetic pole and the diaphragm, and it is necessary to clean them in time before assembly. However, many traditional cleaning methods are to use the sticky cleaning tape, and fine dust is easy to remain, which greatly reduces the assembly effect and the quality of later use.

[0023] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0025] There are several installation sleeves 2 and push plates 9, and the size of a single push plate 9 is the same as that of the installation sleeve 2, and can be selectively used according to the coil specifications.

[0026] Through the mutual cooperation among the cylinder 1, the vertical rod 4, the push plate 9 and the installation sleeve 2, a suitable installation sleeve 2 can be selected according to the inner diameter of the coil and screwed on the cylinder 1, the coil can be sleeved on the outside of the installation sleeve 2, and after the installation sleeve 2 is inserted into the periphery of the magnetic pole, the coil is pushed in by the push plate 9 to prevent the copper wire from being torn off due to the tilt of the coil, thereby ensuring stability during assembly.

[0027] like Figure 2-Figure 4 As shown, the cleaning assembly includes a cleaning ring 10 assembled on the side wall of the mounting sleeve 2. The cross section of the cleaning ring 10 is U-shaped, and a cotton cloth layer 11 is fixedly connected to the side wall of the cleaning ring 10.

[0028] A plurality of clamping blocks 12 are fixedly connected to the inner wall of the cleaning ring 10 . The cross section of the clamping blocks 12 is triangular. A plurality of clamping grooves 13 matching with the clamping blocks 12 are formed on the side wall of the mounting sleeve 2 .

[0029] Specifically, the cleaning ring 10 can be made of rubber material with a certain elasticity to adapt to installation sleeves 2 of different diameters. The clamping block 12 and the clamping groove 13 can be used to limit and fix the cleaning ring 10 on the one hand, and to increase the friction between the cleaning ring 10 and the installation sleeve 2 on the other hand, thereby further increasing stability.

[0030] like Figure 5 As shown, a first magnetic sheet 14 is fixedly connected to the bottom surface of the annular plate 8 , and a second magnetic sheet 15 is fixedly connected to the top surface of the push plate 9 , and the first magnetic sheet 14 and the second magnetic sheet 15 attract each other.

[0033] The method of matching the screw sleeve 17 with the screw hole 16 is a conventional structure. In this solution, it is easy to replace the installation sleeve 2 of different specifications, and there is good sealing between the installation sleeve 2 and the cylinder 1; when cleaning, the cylinder 1 is rotated in the direction of the tightening side, and the installation sleeve 2 will not loosen.

[0034] The working principle of the utility model is as follows: firstly, a suitable mounting sleeve 2 is selected according to the coil specification, and the screw sleeve 17 is screwed into the screw hole 16, and then the cleaning ring 10 is first sleeved on the mounting sleeve 2, so that the clamping block 12 is clamped into the clamping groove 13 for limit fixing, and then the mounting sleeve 2 is inserted into the magnetic pole gap, and the cylinder 1 is rotated to drive the cleaning ring 10 to rotate, and the dust adhering to the magnetic pole is cleaned by the cotton cloth layer 11. After cleaning, the cleaning ring 10 is removed, and the coil is sleeved on the mounting sleeve 2, and the bottom of the mounting sleeve 2 is first extended into the gap. After the position is aligned, the pressing plate 6 is pressed to drive the movable rod 7 to move downward through the vertical rod 4. The movable rod 7 pushes the coil downward through the push plate 9, so that it can smoothly enter the magnetic pole gap, so as to achieve the purpose of smooth assembly, effectively prevent the problem of copper wire breaking caused by the tilt of the coil, and increase the quality of later use.

[0035] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
