Description

Technical Field

[0001] The present application relates to the technical field of loudspeaker fixtures, and in particular to a loudspeaker front soldering line adjustment tool. Background Art

[0002] A loudspeaker is a transducer device that converts electrical signals into acoustic signals. It produces sound by vibrating its cone through electromagnetic, piezoelectric, or electrostatic effects, which resonate with the surrounding air. Speakers can be found in home televisions, multimedia home audio systems, outdoor audio systems, cars, karaoke venues, public square broadcasts, and computers, serving as sound-producing units.

[0003] Most speakers require leads to transmit signals, typically made of tinsel wire. One end of the wire is connected to the speaker's voice coil, while the other end is soldered to the speaker's base terminal block. To avoid wire snagging (where the wire hits the base), the wire needs to be angled to allow for a certain length. This requires a wire adjustment jig.

[0004] Currently, most car speakers in the industry are assembled with the paper cone (i.e., the speaker cone) before the lead wires are adjusted and soldered. This process prevents visual inspection of the speaker lead wire curvature. Furthermore, inconsistencies in lead wire alignment can lead to poor bonding. Furthermore, car speaker cones are large, making them difficult to repair. If the lead wires are too short, a rip can occur. In severe cases, the cone can be pulled, causing it to vibrate diagonally, leading to rubbing noises on the voice coil and magnetic circuit, resulting in significant damage.

[0005] The industry also uses a pre-soldering process. As the name suggests, pre-soldering involves adjusting the leads and soldering them before installing the paper cone. Insert-type wire adjustment jigs are commonly used in this pre-soldering process to adjust the curvature of the speaker's wires to meet the required sound quality. However, a common problem with these insert-type wire adjustment jigs in the speaker industry is that the wires can rebound or even fall after adjustment, resulting in a high rate of poor sound quality, failing to meet the required speaker sound quality. Utility Model Content

[0006] The main technical problem solved by this application is to provide a speaker front soldering line adjustment tool.

[0007] The present application proposes a speaker front soldering wire adjustment tool, comprising:

[0008] The fixture body, brocade thread positioning column, and bracket positioning column;

[0009] The fixture body has a top surface for fitting the elastic wave of the speaker, and a voice coil avoidance hole extending from the top surface to the opposite bottom surface;

[0010] A working notch is also provided on one side of the fixture body, communicating with the voice coil avoidance hole;

[0011] The top surface of the fixture body is also provided with a brocade wire air-avoiding groove, and the brocade wire air-avoiding groove is connected to the voice coil air-avoiding hole and the working gap;

[0012] The brocade wire positioning column is installed in the working gap;

[0013] The bracket positioning column is arranged on the outside of the fixture body.

[0014] In some optional embodiments, the bracket positioning column is vertically upward, and the top end is higher than the top surface.

[0015] In some optional embodiments, the bracket positioning column is close to the working gap.

[0016] In some optional embodiments, when viewed from above, the working gap is a fan-shaped gap having a first side surface and a second side surface.

[0017] In some optional embodiments, the angle between the first side surface and the second side surface is substantially 90 degrees.

[0018] In some optional embodiments, the brocade thread positioning column is vertically installed on the first side and extends horizontally.

[0019] In some optional embodiments, the depth of the working gap is greater than half of the jig body, but does not penetrate the jig body.

[0020] In some optional embodiments, the first side surface and the second side surface are both perpendicular to the top surface.

[0021] In some optional embodiments, the brocade thread avoidance groove extends to the first side surface and the second side surface.

[0022] In some optional implementations, the opening of the voice coil avoidance hole has a chamfer.

[0023] As described above, this application proposes a pre-soldering wire adjustment tool for speakers, suitable for adjusting the curvature of lead wires during the pre-soldering process of, for example, automotive speakers. This application utilizes a novel structure, including wire positioning posts, bracket retaining posts, and wire clearance grooves on the fixture body, to achieve lead adjustment. The technical effects achieved include:

[0024] 1. Compared with the conventional line adjustment process, this application adds a bracket positioning column, the purpose of which is to increase the prevention of mistakes and foolproofness, and to position the speaker basin frame to prevent loosening;

[0025] 2. This application directly opens a circular hole in the middle of the tooling as a voice coil avoidance hole to avoid and fix the voice coil of the speaker;

[0026] 3. This application opens an operating gap on the side of the fixture, and the brocade wire positioning column is set in the operating gap. The operator can pull the lead wire through the operating gap and clamp it on the operating gap to complete the lead wire curvature adjustment;

[0027] 4. This application can adopt a rotating method to put the tooling into the speaker without adjusting the lead wires. After rotating it a certain degree, such as 90 degrees, the bracket clamping column and the speaker basin frame are clamped and fixed. The operator tightens the lead wires and then solders them.

[0028] 5. This application also provides a brocade wire avoidance slot to prevent the brocade wire from being clamped and causing trouble in adjusting the wire;

[0029] 6. The advantages of the jig of the present application are that the curvature of the lead can be adjusted to a satisfactory state before the paper cone is installed (at this time, the lead can be visually observed through the working notch to see if there is any bad condition);

[0030] 7. The jig of this application is convenient to use and operate. The front soldering process is adopted to reduce the risk of not being able to visually observe the lead status due to the obstruction of the basin frame. When risks are found, they can be promptly eliminated and repaired, and temporary measures can be taken to reduce the occurrence of defects.

[0031] In summary, the jig of this application can be used in the speaker manufacturing process. By pre-soldering the speaker, the lead wire curvature can be adjusted before the paper cone is placed. The speaker cone frame is positioned to prevent mistakes, reduce defects, greatly reduce rework and scrap costs, and greatly improve product pass rate. This application helps to improve the common wire adjustment problems in the speaker industry and meet the wire adjustment requirements of speakers. BRIEF DESCRIPTION OF THE DRAWINGS
