Description

Technical Field

[0001] The present application relates to the technical field of loudspeaker fixtures, and in particular to a fixture for positioning the arc of a loudspeaker's double-sided basin frame. 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, often made of brocade wire. To avoid issues like wire hitting the paper cone, the leads need to be angled to allow for a certain length. This requires a cable adjustment fixture.

[0004] Currently, the wire alignment fixtures commonly used in the industry include inserts and inserts, which are positioned on the speaker frame in a single-sided positioning manner. However, in the production of larger speakers such as automotive speakers, the speaker frame is large and will block the wire leads, making it difficult to visually see the wires inside the frame. Common single-sided positioning fixtures have the following drawbacks:

[0005] 1. The unilateral positioning of the fixture to the basin frame has poor stability. When adjusting the wires (adjusting the curvature of the lead wires), if the employee is not skilled, one side of the fixture may easily tilt up, causing the two lead wires to have one side longer and one side shorter. Moreover, because the lead wires are blocked by the basin frame and cannot be visually detected by the employee, the speaker will have poor sound quality due to unbalanced vibration.

[0006] 2. Due to the unilateral positioning of the fixture, the lead wires are prone to loosening and / or lengthening during the wire adjustment process, which ultimately leads to poor wiring and poor speaker sound quality. Utility Model Content

[0007] The main technical problem solved by this application is to provide a fixture for positioning the arc of the double-sided basin frame of a loudspeaker.

[0008] The present application proposes a double-sided speaker basin positioning arc jig, comprising: a first positioning member and a second positioning member connected by a crossbeam; the first positioning member is used to position to the first side of the speaker basin with a terminal board, and the bottom of the first positioning member is provided with two lead wire grooves for positioning and adjusting the speaker leads; the second positioning member is used to position to the second side of the speaker basin opposite to the first side.

[0009] In some optional embodiments, a magnetic member is provided on the crossbeam, and the magnetic member is used to magnetically fix the crossbeam to the T-iron of the speaker.

[0010] In some optional embodiments, the magnetic member is a magnetic steel embedded in the middle position of the beam.

[0011] In some optional embodiments, a first positioning groove for being clamped on the speaker basket is formed at the bottom of the first positioning member, and the two clamping wire grooves are respectively located on both sides of the first positioning groove.

[0012] In some optional embodiments, a second positioning groove for being clamped on the speaker basin frame is formed at the bottom of the second positioning member, and the second positioning groove is substantially the same size as the first positioning groove.

[0013] In some optional embodiments, the card lead groove is a V-shaped groove.

[0014] In some optional embodiments, the inner sidewall of the V-shaped groove is lower than the outer sidewall.

[0015] In some optional embodiments, the first positioning member and the second positioning member are parallel to each other and substantially perpendicular to the beam.

[0016] In some optional embodiments, each corner of the first positioning member and each corner of the second positioning member are rounded.

[0017] In some optional embodiments, the crossbeam, the first positioning member and the second positioning member are integrally formed metal members.

[0018] As described above, this application proposes a fixture for positioning the curvature of a speaker frame on both sides. The fixture includes a first positioning member and a second positioning member connected by a crossbeam. The first positioning member and the second positioning member can be positioned on opposite first and second sides of the speaker frame in a bilateral positioning manner. By adopting a bilateral positioning method, the technical effects achieved by this fixture include but are not limited to:

[0019] 1. This application adopts 180-degree double-outlet and two-way positioning of the speaker basin frame (that is, positioning one side of the speaker basin frame terminal board + positioning the other side opposite to the terminal board to achieve 180-degree opposite double positioning) to ensure that the fixture is stable and consistent during the line adjustment process. In this way, it can avoid the fixture from warping, and avoid the situation where one side of the lead is longer than the other side, the lead is loose, and / or the lead becomes longer during the line adjustment, thereby ensuring accurate line adjustment and ensuring the sound quality of the speaker.

[0020] 2. The jig of this application is characterized by its simplicity of operation, short lead adjustment time (lead adjustment can be completed immediately after placement in the jig), and ease of operation for operators. Consequently, the jig of this application can significantly shorten the lead adjustment production process, while increasing product production capacity and achieving high consistency and stability.

[0021] 3. In a further preferred embodiment, the present application can attach magnetic parts (such as aluminum iron boron material or other materials, which have been magnetized) to the fixture, and use the magnetic adsorption ability of the magnetic parts to adsorb on the T iron at the bottom of the speaker to achieve the effect of precise positioning of the fixture and the speaker.

[0022] 4. During the production process, the jig of this application generally adopts a 180-degree two-way bilateral basin frame positioning method to adjust the line. Compared with the jig with a single-sided basin frame positioning, it can increase the stability of the positioning jig during soldering, ensure the consistency of lead adjustment, and reduce the product defect rate caused by lead adjustment problems to close to 0%.

[0032] In some optional embodiments, a magnetic member 5 is provided on the crossbeam 3, and the magnetic member 5 is used to magnetically fix the crossbeam 3 to the T-iron of the speaker, thereby further improving the stability of the fixture positioning and preventing loosening.

[0033] In some optional embodiments, the magnetic member 5 is a magnet embedded in the middle of the beam 3, including but not limited to a magnet made of aluminum iron boron.

[0034] In some optional embodiments, a first positioning groove 101 for being clamped on the speaker basin frame is formed at the bottom of the first positioning member 1 , and two clamping wire grooves 4 are respectively located on both sides of the first positioning groove 101 .

[0035] In some optional embodiments, a second positioning groove 201 for being clamped on the speaker basin frame is formed at the bottom of the second positioning member 2 , and the second positioning groove 201 is substantially the same size as the first positioning groove 101 .

[0036] In some optional embodiments, the card lead groove 4 is a V-shaped groove.

[0037] In some optional embodiments, the inner sidewall of the V-shaped groove is lower than the outer sidewall, so that a notch can be formed on the outer sidewall to facilitate the lead to be inserted into the V-shaped groove.

[0038] In some optional embodiments, the first positioning member 1 and the second positioning member 2 are both flat plates, parallel to each other, and substantially perpendicular to the beam 3 .
