Problems solved by technology

Existing loudspeaker panels are generally connected to the speaker by threads, and at the same time, the speaker panel is generally provided with several thin and dense sound amplification holes in the middle of the panel, which is easy to contaminate a large amount of dust on the sound amplification holes and is not easy to clean. When using speakers, it reduces the spread of the sound effect

Embodiment 1

[0028] see Figure 1-Figure 4 , a speaker panel dust-proof film, including waterproof coating 1, thermal conductive coating 2 and antistatic coating 3, the upper surface of waterproof coating 1 is connected with thermal conductive coating 2, and the upper surface of thermal conductive coating 2 is connected with anti-static coating 2 Electrostatic coating 3, a bonding layer 11 is connected around the lower surface of waterproof coating 1, and waterproof coating 1 is composed of raw materials in the following weight ratios: 30-40 parts of expanded polytetrafluoroethylene, 3-5 parts of aluminum stearate parts, 10-15 parts of styrene-acrylic emulsion, 20-30 parts of methanol and 15-20 parts of sodium hydroxide aqueous solution, the waterproof membrane made of expanded polytetrafluoroethylene material has good waterproofness and can transmit sound, suitable for The speaker panel is convenient for the speaker to transmit sound.

[0029] The bonding layer 11 includes an epoxy glue ...

Embodiment 2

[0049] The structure in this embodiment is the same as that in Embodiment 1, and the raw materials of the following weight ratios are taken:

[0050] 40 parts of expanded polytetrafluoroethylene, 5 parts of aluminum stearate, 10 parts of styrene-acrylic emulsion, 30 parts of methanol and 15 parts of sodium hydroxide aqueous solution;

[0051] 10 parts of graphene, 40 parts of phenolic resin, 2 parts of surfactant, 10 parts of polyethylene, 20 parts of water-based polyurethane, 10 parts of absolute ethanol, 5 parts of water, 0.1 part of concentrated hydrochloric acid;

[0052] 60 parts of polypropylene, 20 parts of polyurethane, 15 parts of antistatic agent, 6 parts of ultraviolet absorber and 8 parts of crosslinking agent.

[0053] The dustproof film was processed according to the preparation method of Example 1.

Embodiment 3

[0055] see Figure 5 , a speaker panel dust-proof film, including waterproof coating 1, thermal conductive coating 2 and antistatic coating 3, the upper surface of waterproof coating 1 is connected with thermal conductive coating 2, and the upper surface of thermal conductive coating 2 is connected with anti-static coating 2 Electrostatic coating 3, the lower surface of the waterproof coating 1 is connected with a bonding layer 11, the bonding layer 11 is a magnet material, the bonding layer 11 and the waterproof coating 1 are connected by glue, and the magnet material is connected by glue, through The magnet material is attracted to the speaker panel, and the dust-proof film is a detachable structure. When the speaker is not in use, the dust-proof film can be attracted to the speaker panel to achieve dust-proof effect. When the speaker is used, the dust-proof film can be removed. Below, the dustproof film can be cleaned.

[0056] Remove the raw materials by weight: 35 parts ...

Abstract

The invention discloses a speaker panel dust-proof film and a preparation method thereof, comprising a waterproof coating, a heat-conducting coating and an antistatic coating, the upper surface of the waterproof coating is connected with a heat-conducting coating, and the upper surface of the heat-conducting coating is An antistatic coating is connected, and a week of the lower surface of the waterproof coating is connected with an adhesive layer, and the waterproof coating is composed of raw materials in the following weight ratio: 30-40 parts of expanded polytetrafluoroethylene, 3-40 parts of aluminum stearate 5 parts, 10-15 parts of styrene-acrylic emulsion, 20-30 parts of methanol and 15-20 parts of sodium hydroxide aqueous solution. The present invention proposes a speaker panel dust-proof film and its preparation method, through waterproof coating, heat-conducting coating and anti-static coating, adding expanded polytetrafluoroethylene in the waterproof coating, which has good water resistance and can transmit sound , suitable for the speaker panel, which is convenient for the speaker to transmit sound. Graphene material is added in the thermal conductive coating, which has good thermal conductivity and improves the heat dissipation effect of the speaker. In addition, the anti-static coating can prevent the surface of the film layer from absorbing dust.

Description

technical field [0001] The invention relates to the technical field of loudspeaker dustproofing, in particular to a loudspeaker panel dustproof film and a preparation method thereof. Background technique [0002] Most of the loudspeakers in the prior art are external magnetic loudspeakers, and their general structure includes a cone frame, a sound cone, a magnetic circuit, a voice coil, and the like. The basin frame is mainly used to install and support the components in the speaker. The basin frame includes an outer ring for fixing the sound cone, an inner ring for fixing the magnetic circuit, and a connecting rib arranged between the inner ring and the outer ring. The production generally adopts ABS injection molding. The existing loudspeaker panel is generally connected to the loudspeaker through threads. At the same time, the loudspeaker panel generally has several fine and dense amplifying holes in the middle of the panel, which is easy to be contaminated with a large ...
