Problems solved by technology

[0003] However, when using artificial glue to paste the diaphragm on the hanging edge, the sticking position is prone to shift, making the center of the diaphragm and the hanging edge not concentric, which will increase the distortion of the speaker and affect the quality of the speaker
In addition, the existing horns that use paper-based horn diaphragms usually have poor performance at high frequencies.

Embodiment Construction

[0019] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with specific embodiments and accompanying drawings.

[0020] see figure 1 with figure 2 , a speaker sound film 100 is installed on a speaker (not shown in the figure), and includes a diaphragm 10 and an overhang portion 20 .

[0021] see image 3 , the diaphragm 10 is circular, made of acrylonitrile-butadiene-styrene copolymer (Acrylonitrile Butadiene Styrene, ABS) plastic, and a layer of nanometer material is electroplated on the surface.

[0022] The hanging edge portion 20 is in the shape of a ring, and is in-moulded on the outer periphery of the diaphragm 10 by room temperature vulcanized silicone rubber (RTV), and a circle is formed on the inner edge of the outer surface of the hanging edge portion 20. An annular mounting groove 21. The outer periphery of the diaphragm 10 is fi...

Abstract

The invention discloses a loudspeaker voice diaphragm and a making method thereof. The loudspeaker voice diaphragm is arranged on a loudspeaker, and comprises a vibrating diaphragm and a dangling edge portion, wherein the vibrating diaphragm is made of acrylonitrile butadiene styrene plastic; the surface of the vibrating diaphragm is electroplated with a layer of nanomaterial; and the dangling edge portion is molded on an outer periphery of the vibrating diaphragm in an in-mold way through room temperature vulcanized silicone rubber. The loudspeaker voice diaphragm disclosed by the invention has the characteristics that the vibrating diaphragm is made of the acrylonitrile butadiene styrene plastic; the surface of the vibrating diaphragm is electroplated with a layer of nanomaterial; and then, the dangling edge portion is molded on an outer periphery of the vibrating diaphragm in the in-mold way through the room temperature vulcanized silicone rubber. The loudspeaker using the loudspeaker voice diaphragm disclosed by the invention has a better high-frequency effect than a loudspeaker using a loudspeaker voice diaphragm made of a paper material, and the quality of the loudspeaker is improved.

Description

technical field [0001] The invention relates to a horn, in particular to a horn sound film and a manufacturing method thereof. Background technique [0002] An existing speaker sound diaphragm includes a circular plastic material hanging edge and a paper circular diaphragm. The hanging edge is in the shape of a hollow ring, and the diaphragm is manually glued to the hollow of the hanging edge and closed in the middle of the hanging edge. The center of the diaphragm is concentric with the center of the hanging edge. [0003] However, when the vibrating membrane is pasted on the hanging edge with artificial glue, the sticking position is prone to shift, making the center of the diaphragm and the hanging edge not concentric, which will increase the distortion of the speaker and affect the quality of the speaker. In addition, the existing horns that use paper-based horn diaphragms generally have poor performance at high frequencies. [0004] Therefore, it is necessary to provi...
