Abstract
The invention discloses a plane vibrating diaphragm and application thereof. The plane vibrating diaphragm comprises a vibrating diaphragm body and a voice coil which is arranged on the vibrating diaphragm body, wherein the voice coil is a grapheme pattern which is printed on the vibrating diaphragm body or arranged on the vibrating diaphragm body by printing. As the grapheme voice coil graph is printed on the vibrating diaphragm body, the acoustic performance of the plane vibrating diaphragm is improved, the weight is light, the heat dissipation is rapid, the production and processing are facilitated, and the production cost is reduced.
Description
Technical field
the present invention relates to loud speaker field, particularly a kind of plane diaphragm and the loud speaker that uses this vibrating diaphragm.
Background technology
the vibrating diaphragm of general loud speaker is all done tapered or ball top shape, in order to meet the requirements of sound and power effect, volume is also very large, is difficult to meet the requirement of some compact electronic devices such as mobile phone, and the material that will use technique in manufacturing process is very complicated.Appearance along with flat film loudspeaker, solved this problem, but general flat film loudspeaker adopts photoetching technique in metal forming, to form voice coil loudspeaker voice coil figure and makes plane diaphragm, be subject to the impact of vibrating diaphragm and voice coil loudspeaker voice coil material, existed the problem that production cost is high, input power is low and electro-acoustic conversion efficiency is low.
Summary of the invention
the object of this invention is to provide a kind of better performances and plane diaphragm convenient for production and the loud speaker of utilization thereof.
for achieving the above object, the technical solution used in the present invention is: a kind of plane diaphragm, and it comprises vibrating diaphragm body, is arranged on the voice coil loudspeaker voice coil on described vibrating diaphragm body, and described voice coil loudspeaker voice coil is for by printing or printing the Graphene figure being arranged on described vibrating diaphragm body.
preferably, described vibrating diaphragm body is wherein a kind of of macromolecule vibrating diaphragm, metal vibration diaphragm, alloy vibrating diaphragm, ceramic vibrating diaphragm, graphite vibrating diaphragm, liquid crystal polymer vibrating diaphragm, highly elastic fiber vibrating diaphragm, composite diaphragm.
the production method of above-mentioned plane diaphragm, comprises the following steps:
1) Graphene is printed on and on vibrating diaphragm body, forms voice coil loudspeaker voice coil figure.
2) the vibrating diaphragm body that is printed with voice coil loudspeaker voice coil figure is passed through to the high-temperature baking of 100 ℃-500 ℃.
preferably, the mode of printing in step 1) is a kind of in intaglio printing, letterpress, orifice plate printing or electronic printable.
a kind of flat film loudspeaker that uses above-mentioned plane diaphragm.
because technique scheme is used, the present invention compared with prior art has following advantages:
because the present invention adopts the voice coil loudspeaker voice coil figure of printing Graphene on vibrating diaphragm body, the acoustical behavior of plane diaphragm is improved, lightweight, rapid heat dissipation has facilitated production and processing simultaneously, has reduced production cost.
Accompanying drawing explanation
accompanying drawing 1 is plane diaphragm schematic diagram.
in above accompanying drawing: 1, vibrating diaphragm body; 2, voice coil loudspeaker voice coil.
Embodiment
below in conjunction with embodiment shown in the drawings, the invention will be further described:
embodiment mono-: shown in accompanying drawing 1, and a kind of plane diaphragm, it comprises vibrating diaphragm body 1 that macromolecular material makes, is arranged on the voice coil loudspeaker voice coil 2 on vibrating diaphragm body 1, and voice coil loudspeaker voice coil 2 is Graphene figure for being arranged on vibrating diaphragm body 1 by printing.
the production method of the present embodiment plane diaphragm comprises the following steps:
1) Graphene is printed to the figure of voice coil loudspeaker voice coil 2 by the mode of electronic printable on vibrating diaphragm body 1.
2) the vibrating diaphragm body 1 that is printed with the figure of voice coil loudspeaker voice coil 2 is passed through to the high-temperature baking of 100 ℃-500 ℃, Graphene figure is dried.
energising back plane vibrating diaphragm is driven in magnetic gap comprehensively, and the present embodiment plane diaphragm is thin and light, and active force does not have the difference of phase place, and conversion efficiency is high, and frequency response is broad, and distortion is little, not only good promotion but also control well, and transient response is very good.
because the present embodiment adopts the voice coil loudspeaker voice coil figure of printing Graphene on vibrating diaphragm body 1, the acoustical behavior of plane diaphragm is improved, lightweight, rapid heat dissipation has facilitated production and processing simultaneously, has reduced production cost.
above-described embodiment is only explanation technical conceive of the present invention and feature, and its object is to allow person skilled in the art can understand content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences that Spirit Essence is done according to the present invention change or modify, within all should being encompassed in protection scope of the present invention.
