Embodiment Construction

[0050] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0051] (Embodiment 1)

[0052] figure 1 It is a flow chart showing the manufacturing method of the paper-made diaphragm for speakers which concerns on Embodiment 1 of this invention. In Embodiment 1, the diaphragm for a speaker is demonstrated as an example of the paper-made part for speakers. The same applies to other paper-made parts for speakers, for example, an auxiliary cone for speakers, a dust cover for speakers, and other paper-made parts for speakers.

[0053] like figure 1 As shown, the material of the paper-made vibration plate for the speaker is put into a container for cracking fibers, and the fine fibers are cracked by the fiber cracking process.

[0054] Then, the defiberized material is salvaged into a metal mold and a wire mesh placed on the mold by a papermaking process, and only water is drained, and the material is deposited to form a shape as ...

Abstract

This invention provides a method for manufacturing a component for a speaker by papermaking, which is large in freedom of regulation of properties and sound quality and is high in productivity. This method can be realized by adopting a blasting step as a step of defibrating a papermaking material. Alternatively, this method may be realized by comprising a step of mixing a papermaking material with a liquid, a step of size-reducing the material by applying pressure to the mixed liquid provided by the mixing step, passing the pressurized mixed liquid through an orifice, and then allowing the mixed liquid to collide with a vessel wall, and a step of papermaking involving the size-reduced material.

Description

technical field [0001] The present invention relates to a manufacturing method of paper parts for speakers used in various audio equipment; paper parts for speakers, vibration plates for speakers, auxiliary paper cones for speakers, and dust covers for speakers manufactured by the method; Speakers with these parts removed. Background technique [0002] With the rapid development of digital technology, the performance of electronic equipment such as audio equipment and video equipment has been greatly improved compared with the past. [0003] As the performance of such electronic devices increases, there is a strong demand in the market to improve the performance of speakers used in these electronic devices. [0004] For speakers whose performance is strongly demanded in the market, it is necessary to improve the vibrating part centering on the diaphragm, which plays a large role in determining its sound quality, among the constituent parts of the speaker so as to have high ...
