Problems solved by technology

The existing technology has a horn mesh structure, which is usually integrally formed on the shell during injection molding of the shell. It includes through holes and blind holes. Since the bottom of the blind hole is mostly flat, when spraying, especially when spraying such as For light-colored paint such as silver gray, the bottom of the blind hole is easy to be colored, and there is a color difference with the through-hole part. Most of them can see the phenomenon of "speaker black circle", and the appearance consistency is poor, which affects the appearance of the TV.

Embodiment 1

[0044] Embodiment 1, referring to the accompanying drawings, a speaker mesh structure of the present invention, it includes a through hole 1 and a blind hole 2 integrally formed on the casing 10; the through hole 1 has a circular longitudinal cross section. Cross-section is a trapezoidal upper hole 11 and a circular longitudinal section is a trapezoidal lower hole 12. The upper hole 11 communicates with the lower hole 12; A trapezoidal outer hole 21 and a conical inner hole 22 are formed. The outer hole 21 communicates with the inner hole 22 . The inner hole 22 gradually shrinks downward from the bottom of the outer hole 21 .

[0045] Wherein, the diameter A of the bottom port of the upper hole 11 of the through hole 1 is 1 millimeter. Of course, the diameter A of the bottom port of the upper hole 11 of the through hole 1 can be specifically determined according to the size and appearance of the TV or household appliances. The value range is 0.5-3 mm, and then according to the...

Embodiment 2

[0059] Embodiment two, a kind of loudspeaker mesh structure of the present invention, it comprises the through hole 1 and the blind hole 2 that are integrally formed on the casing 10; The bottom port diameter A of hole 11 on the through hole 1 is 1 millimeter; The difference is that the hole depth D of the upper hole 11 of the through hole 1, the upper port diameter B of the upper hole 11 of the through hole 1, the hole center distance C of the through hole 1, the upper port diameter E of the lower hole 12 of the through hole 1, The hole depth G of the outer hole 21 of the blind hole 2, the upper port diameter M of the outer hole 21 of the blind hole 2, the bottom port diameter N of the outer hole 21 of the blind hole 2, the hole center distance P of the blind hole 2, and the inner hole 22 of the blind hole 2 The hole depth L and the hole center distance Q between the through hole 1 and the blind hole 2 are respectively calculated by the following formulas in millimeters based ...

Embodiment 3

[0071] Embodiment three, a kind of loudspeaker net structure of the present invention, it comprises through hole 1 and blind hole 2 integrally formed on the casing 10; The diameter A of the bottom port of hole 11 on through hole 1 is 1 millimeter; Same as embodiment one The difference is that the hole depth D of the upper hole 11 of the through hole 1, the upper port diameter B of the upper hole 11 of the through hole 1, the hole center distance C of the through hole 1, the upper port diameter E of the lower hole 12 of the through hole 1, The hole depth G of the outer hole 21 of the blind hole 2, the upper port diameter M of the outer hole 21 of the blind hole 2, the bottom port diameter N of the outer hole 21 of the blind hole 2, the hole center distance P of the blind hole 2, and the inner hole 22 of the blind hole 2 The hole depth L and the hole center distance Q between the through hole 1 and the blind hole 2 are respectively calculated by the following formulas in millimet...

Abstract

The disclosed horn mesh structure comprises: both integrated on the shell, a throughout hole, including a connected top and bottom holes both with circle cross-section and trapezoid longitudinal section; and a blind hole, including a outer hole with circle cross-section and trapezoid longitudinal section and a connected conical inner hole. Wherein, the shape both of the throughout hole and blind hole is calculated by formula with bottom hole diameter A as reference. This invention can eliminate horn black ring on TV shell, and improves production efficiency.

Description

technical field [0001] The invention relates to a speaker net, in particular to an injection-molded speaker net equipped with household appliances such as CRT, PDP, and LCD televisions.
