Description

Technical Field

[0001] The present application relates to the technical field of loudspeaker jigs, and in particular to a jig for centering and fitting a loudspeaker concave-top dust cap. Background Art

[0002] A speaker is a transducer device that converts electrical signals into acoustic signals. Speakers can be installed in home televisions, multimedia home audio systems, outdoor audio systems, cars, karaoke venues, public square broadcasting systems, computers, and other applications, serving as sound-producing units. The speaker cone (cone, paper cone) typically requires a dust cap. Dust caps come in various shapes, including convex (convex top) and concave (concave top).

[0003] At present, in the loudspeaker industry, the capping (putting on) method of the concave-top dust cap mainly relies on manual capping by operators, which requires high skills of operators and is prone to the problem of dust cap displacement, affecting the front appearance of the speaker. In addition, because the dust cap capping process requires pre-gluing on the speaker drum paper for bonding, the fingers can easily scratch the glue during manual capping, resulting in local glue deficiency after bonding, causing poor air leakage of the dust cap. At the same time, the residual glue on the hands can easily contaminate the surface of the speaker, resulting in poor appearance of glue stains.

[0004] Some companies are currently using automated methods, using automated suction cups to absorb and cap dust caps. However, the centering of the dust caps cannot be guaranteed, and the use of automated suction cups can cause deformation of thinner dust caps, especially aluminum caps, which cannot be repaired or reused once deformed. Utility Model Content

[0005] The main technical problem solved by the present application is to provide a fixture for centering and putting on the concave dust cap of a loudspeaker.

[0006] The present application proposes a fixture for centering and fitting a loudspeaker concave dust cap, comprising:

[0007] The movable block has a top surface and a bottom surface, wherein the top surface is provided with a concave cavity, and the bottom of the concave cavity is provided with a through hole extending through the bottom surface;

[0008] a speaker positioning column, arranged on the top surface of the movable block;

[0009] A dust cap positioning column, comprising a head portion falling into the concave cavity and a column body passing through the through hole, wherein the head portion is used to position the concave top dust cap;

[0010] A base, connected to the bottom of the column;

[0011] The spring is sleeved on the column and located between the movable block and the base.

[0012] In some alternative embodiments, a ring-shaped cavity is formed around the lower section of the through hole in the movable block, and the upper section of the spring is located in the ring-shaped cavity.

[0013] In some alternative embodiments, the top end of the spring abuts against the top of the ring-shaped cavity, so that the movable block is subjected to the upward elastic force of the spring.

[0014] In some alternative embodiments, the width of the head is equivalent to the width of the concave top dust cap.

[0015] In some alternative embodiments, the top surface of the head is conformal to the concave top dust cap.

[0016] In some alternative embodiments, the speaker positioning column has at least two, which are arranged outside the concave cavity.

[0017] In some alternative embodiments, the highest point of the top surface of the head is flush with the upper surface of the movable block, and the speaker positioning column protrudes from the upper surface of the movable block.

[0018] In some alternative embodiments, when the movable block is subjected to downward pressure, it moves downward relative to the dust cap positioning column and compresses the spring.

[0019] In some alternative embodiments, the inner diameter of the concave cavity is greater than the inner diameter of the through hole, and the diameter of the head is greater than the diameter of the column.

[0020] In some alternative embodiments, the movable block has a circular or square top view.

[0021] The present application proposes a speaker concave top dust cap centering and cap fitting jig, which belongs to a kind of speaker dust cap fitting jig. It mainly aims at the centering and deformation problems of concave top dust cap and is suitable for high-quality centering and cap fitting of concave top dust cap in the speaker manufacturing process. The jig adopts the above technical scheme and achieves the following technical effects:

[0022] (1) By adopting the speaker positioning column and the dust cap positioning column, the speaker and the dust cap are double-positioned and continuously guided, which realizes the function of centering and cap fitting (covering) of the concave top dust cap under continuous guiding and limiting, and solves the technical problem of appearance and performance caused by the inclination of the speaker during cap fitting;

[0023] (2) The spring and the movable block are limited and matched, which ensures the consistency of the cap fitting force when the dust cap is fitted, and improves the problem of insufficient 10~12KHz frequency bandwidth of the speaker frequency response curve caused by the improper fitting of the dust cap.

[0024] (3) The head of the dustproof cap positioning column is used to position the concave top dustproof cap, and the head has a large supporting area. By using this large-area fitting support method, the problem of deformation of the dustproof cap caused by small-area adsorption is avoided, especially the risk of irreversible deformation of the dustproof cap made of light and thin materials such as aluminum caused by adsorption is avoided.
