preparation example Construction

[0034] The preparation method of the drum paper provided by the invention can coat the surface of carcasses of various colors with pigment coatings, so as to obtain the drum paper with required pigments. The production cost is low, the cycle is short, simple and easy, and suitable for large-scale production.

[0035] It can be understood that the carcass in the present invention can be black or other colors. In order to reduce production costs, the carcass can be selected as black carcass.

[0036] In some embodiments of the present invention, the pigment coating includes a color layer composed of any one or at least two of white, yellow, blue, green or pink; preferably a white coating.

[0037] Drum paper with different pigments can be obtained by selecting paints of different colors to make the pigment coating.

[0038] In some embodiments of the invention, the carcass is a paper carcass. Paper carcasses are lightweight, sensitive and low cost.

[0039] In some embodimen...

Embodiment 1

[0070] Such as figure 1 As shown, the present embodiment is a speaker drum paper, which includes a body 10, and the surface of the body 10 is coated with a pigment coating 20.

[0071] Wherein, the carcass 10 is a carcass made of paper, the pigment coating 20 is a white coating, and the thickness of the white coating is 25 microns. Carcass 20 edge is provided with the drum paper limit of rubber material.

[0072] The preparation method of the drum paper for loudspeaker in this embodiment is as follows: first prepare a carcass with a black pulp with a beating degree of 19°SR, and then coat a white coating on the surface of the black carcass to obtain the drum paper for a speaker. Wherein, the drum paper for the loudspeaker is obtained by drying after coating the white coating on the surface of the carcass, the drying temperature is 55° C., and the drying time is 20 minutes.

Embodiment 2

[0074] This embodiment is a kind of drum paper for a loudspeaker. The difference from Embodiment 1 is that the pigment coating in this embodiment is a light blue coating.

[0075] The preparation method of the speaker drum paper in this embodiment is as follows: first prepare a carcass with black pulp, and then apply a light blue coating on the surface of the black carcass to obtain the speaker drum paper.

[0076] Others are the same as in Example 1.

Abstract

The invention provides loudspeaker drum paper, a preparation method thereof and a loudspeaker comprising the same, and relates to the technical field of loudspeakers. The loudspeaker drum paper comprises a carcass, and the carcass surface is coated with pigment coating. The drum paper can alleviate the technical problems of single drum color, low production rate of other color drum paper, and highproduction cost of the existing drum paper, and the technical effects of improving the diversity of the color of the drum paper, reducing the production cost and increasing the yield are achieved.

Description

technical field [0001] The invention relates to the technical field of loudspeakers, in particular to a drum paper for a loudspeaker, a preparation method thereof and a loudspeaker containing the same. Background technique [0002] The drum paper is the main sound-generating part in the speaker. Carcasses in drum paper are generally copied from pulp. At present, due to the poor production environment of drum paper, the drum paper currently on the market is mostly black in order to improve the yield. [0003] If you produce drum paper with other pigments, such as white drum paper, due to the poor environment, if dirt enters the white pulp during the production process, it is easy to cause the white drum paper produced to be a defective product, resulting in a low yield of white drum paper. lower. If you want to directly copy white carcasses, you must build an independent workshop, papermaking pool, and paper machine, so the input cost is relatively high, and the demand for...
