Description

Technical Field

[0001] This application relates to the technical field of speaker manufacturing, and particularly relates to a speaker winding jig. Background Art

[0002] The moving coil speaker is a relatively common type of speaker, which mainly includes a voice coil, a paper cone, a spider, and a magnetic system. When a changing current passes through the voice coil wire on the voice coil, a changing magnetic field will be generated. This changing magnetic field interacts with the magnetic system to generate a driving force, causing the paper cone connected to the voice coil to vibrate and emit sound. Among them, the voice coil is connected to the spider, and the spider is used to ensure that the voice coil can only move in the vertical direction. Usually, the voice coil wire on the voice coil is connected to the terminal board of the speaker through a brocade silk thread, and the brocade silk thread is used as the path for transmitting the current signal.

[0003] Currently, there are usually two wiring methods (i.e., the method of connecting the brocade silk thread) for speakers in the industry.

[0004] The first one is that the voice coil comes with a brocade silk thread, and this brocade silk thread is directly welded to the terminal board. In this way: due to structural limitations, the space between the spider and the paper cone of the speaker is designed to be small. At the same time, when the distance between the voice coil wire outlet position and the terminal board is far, the travel of the brocade silk thread is long at this time. Under the high-power vibration state, it is extremely easy for the brocade silk thread to hit the paper cone or the spider, resulting in the troublesome wire hitting problem, which seriously affects the sound quality of the speaker.

[0005] The second one is the pre-welding line process. A hole is opened on the paper cone. After the voice coil wire and the brocade silk thread are welded at the position where the hole is opened on the paper cone, the brocade silk thread is then welded to the terminal board. In this way: the travel of the brocade silk thread is reduced, and the wire hitting problem is improved, but the problem of false soldering is likely to occur. In order to ensure the quality of the product, usually, a process of pre-winding the voice coil lead and the brocade silk thread is added before the front-line welding. Currently, the speaker winding process is all manual winding. The tightness of the winding and the height consistency of the winding are unstable, and the skill requirements for the operators are high, and the operation time is long, which affects the production efficiency. Summary of the Utility Model

[0006] The main technical problem to be solved by this application is to provide a speaker winding jig.

[0007] The present application provides a speaker winding jig for winding the voice coil leads of a speaker around a silk thread. The speaker winding jig includes: a rotating shaft including a lower end face and a positioning hole opened upward from the lower end face, the positioning hole being used to sleeved on the silk thread; a wire-hooking buckle disposed on the side of the lower end of the rotating shaft for hooking the voice coil leads; a handle sleeved outside the rotating shaft, the rotating shaft being able to rotate relative to the handle; when the rotating shaft rotates, the wire-hooking buckle hooks the voice coil leads to rotate with the rotating shaft, so that the voice coil leads are wound around the silk thread.

[0008] In some alternative embodiments, the wire-hooking buckle includes a first part connected to the rotating shaft and a second part extending along the circumferential direction of the rotating shaft, and a gap is formed between the second part and the side surface of the rotating shaft.

[0009] In some alternative embodiments, the width of the gap is smaller closer to the first part.

[0010] In some alternative embodiments, the thickness of the second part is larger closer to the first part.

[0011] In some alternative embodiments, the outer side surface of the second part is arc-shaped and coaxial with the rotating shaft.

[0012] In some alternative embodiments, the first part and the second part form an L shape.

[0013] In some alternative embodiments, the rotating shaft is made of plastic or metal, and the wire-hooking buckle is made of metal.

[0014] In some alternative embodiments, the speaker winding jig further includes a rotating head; the upper end of the rotating shaft exposes out of the handle and is fixedly connected to the rotating head, and the rotating head is configured to drive the rotating shaft to rotate when being forced to rotate.

[0015] In some alternative embodiments, the speaker winding jig further includes a fixing block; the fixing block is sleeved on the rotating shaft, and the handle is located between the rotating head and the fixing block.

[0016] It can be seen from the above technical solutions that the embodiments of the present application have the following advantages:

It winds the wire by rotating the jig, realizes the function of quickly winding the front-line speakers, can improve the winding efficiency, can improve the winding tightness, can realize the positioning of the length of the voice coil lead wire, and can control the exposed length of the brocade silk thread through the positioning holes, solving the risk of affecting the assembly of the dust cap due to the too-high lead head, and is applicable to the winding assistance of front-line speakers. Moreover, this jig is easy to operate, reduces the skill requirements for operators, and greatly shortens the training cycle of operators. BRIEF DESCRIPTION OF THE DRAWINGS
