Abstract
The invention relates to the field of electro-acoustic industry, in particular to an ultra-thin and ultra-light loudspeaker vibration sound film which has small vibration area and can generate mega bass. The loudspeaker vibration sound film is used in a loudspeaker, and the sound film is formed by bonding a fiber layer, a cork wood layer and another fiber layer together in turn. The beneficial effect of the loudspeaker vibration sound film of the invention is as follows: a fiber surface sound cone of the invention can meet the demand that a small-bore sound cone can generate mega bass and large-bore sound cone can generate high frequency sound. The fiber surface sound cone of the invention is prepared from a composite material and solves the problem that the cone and concave sound cone occupy too much space of the loudspeaker. When cork wood is adopted to prepare the composite material sound cone, the internal loss is increased by 50%, and when fiber cloth is used as the surface of the composite material, the Young modulus value of the sound cone is increased by 60% compared with NXT flat panel vibration film.
Description
Technical field
The present invention relates to the electroacoustic industry field, refer more particularly to a kind of ultra-thin and ultra-light, the vibration area is little and can make the loudspeaker vibration sound film of mega bass.
Background technology
Along with the continuous progress of society, China's living standards of the people are also improving constantly.Industry at loud speaker has also had very big development, but still also there is following some shortcomings part, existing loudspeaker cone and sound film, it all is cone type, it is relatively heavier to be processed into loud speaker, takes up space, though also have existing NXT plane cellular board sound film to reduce volume, but (low frequency is abundant inadequately, and voice is clear inadequately) and curve aspect (high frequency extends not enough) aspect tonequality.Concerning present electroacoustic industry development, new material and development of science and technology have promoted the development of electroacoustic industry, but what change present numerous loud speaker does not still have, the loud speaker that low frequency is good is all quite heavy, volume is excessive, present stage audio amplifier loud speaker, auto loud hailer, the speaker product that comes to this, bulky loud speaker, high frequency lack again very much, and the generation of coaxial loudspeaker is just arranged, also there is the excessive deficiency of volume in coaxial loudspeaker, along with development of science and technology, the utilization in space, much new products comes out of the stove, as the LED TV, LCD TV, notebook computer wishes that the loud speaker low frequency is abundant, intermediate frequency is clear bright, and it all is the pursuit of modern consumer that high frequency extends.
Based on the weak point of existing sound film of loudspeaker, the inventor has developed the present invention's a kind of " loudspeaker vibration sound film ".
Summary of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art technical problem to be solved is: a kind of ultra-thin and ultra-light is provided, and the vibration area is little and can make the loudspeaker vibration sound film of mega bass.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of loudspeaker vibration sound film is used for loud speaker, and described sound film is made up of fibrage, cork wood layer and the fibrage of fitting successively.
Described fibrage is carbon cloth, glass fabric, basalt fiber cloth, aryl fiber cloth, paper fiber or chemical fiber.
Described cork wood layer is made by cork wood or wooden oar paper.
Described fibrolaminar outer surface is pure flat or male and fomale(M﹠F), also can be other rules and random geometry.
Described fibrage, cork wood layer and fibrage are hot-forming after fitting.
A kind of manufacture craft of above-mentioned loudspeaker vibration sound film, this manufacture craft may further comprise the steps:
1), at first is coated with boiling hot heart resin on cork wood layer two surface;
2), then two fibrages scald are had the inclination the cork wood layer upper and lower surface of resin and fitted with being coated with;
3), carry out fibrage and cork wood layer hot-forming again to blank; Hot-forming temperature is 130～150 ℃, and the time of hot pressing is 8-20 minute;
4), the blank after hot-forming is carried out the blank cutting;
5), strike out required finished form with laser cutting machine or cutting die at last.
The beneficial effect of loudspeaker vibration sound film of the present invention is:
Now Fa Ming fiber surface sound cone satisfies the small-bore supper bass of making, and heavy caliber can be made the good sound cone material of high frequency.Fiber surface sound cone of the present invention adopts compound material to make, and solves cone and concave surface sound basin accounts for and the problem of very big speaker volume.Adopt cork wood as composite material sound basin, internal losses improves 50%, the surface of adopting fiber cloth to do composite material, and the Yang Shi mould value contrast NXT plate diaphragm of sound basin improves 60%.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a loudspeaker vibration sound film structure chart of the present invention.
Description of reference numerals:
10, fibrage 20, cork wood layer 100, sound film
