Abstract
The invention discloses a sound box body with cambered surface and spherical shape and a forming method thereof, which belongs to the sound box technical field. The invention uses wood dust or sawdust or wood fibers or combination of the two or the three with any specific flow as base material, which is mixed with binding agent, injected in a mold and formed through combination and compression. The mixture ratio of the binding agent and the base material is 3-5kg/0.1m<2> and the compression ratio is 3: 1-1.5. The invention has the advantages that since mold forming is employed, various anomalously-shaped sound boxes can be made as required; the invention does not need routing, has high product precision, large forming radian, low manufacturing cost and reduces dust pollution; faces are smooth and does not have cross breaks after being formed. The method of the invention can also be used for producing anomalous furniture.
Description
Technical field
The present invention relates to the manufacture method of cambered surface audio amplifier.It specifically is the method for a kind of cambered surface and spherical sound box and moulding thereof.Dominant box technology field.
Background technology
The arc audio amplifier is not only more attractive in appearance than plate shaped audio amplifier, and has a better acoustics, but the method for making curved panel at present is to adopt at reverse side cutting bending method mostly, promptly use thicker density board, usually some parallel rectangular channels of excavation on a side of the plane density board of thickness more than 10 millimeters, with plane density board bending, in groove, pour into glue and fix then.The problem that exists be the manufacturing cost height, rough, have that striped occurs, sound box is heavy, dust pollution is big when producing.Be subjected to the restriction of manufacture method, can't make spherical sound.
Summary of the invention
The method that the purpose of this invention is to provide a kind of cambered surface and spherical sound box and moulding thereof is made the shortcoming of cambered surface sound box to overcome reverse side cutting bending method, and is suitable for mass industrialized production.
The present invention realizes with following technical scheme: a kind of cambered surface and spherical sound box, it is characterized in that with wood chip or sawdust or wood-fibred or three or both by the base-material of making a gesture of measuring arbitrarily that is combined as, mix with binder and add in the mould through the compound compressed moulding; The proportioning of binder and base-material is 3-5kg/0.1m
3Compression ratio is 3:1-1.5.
For strengthening the intensity of sound box, can also in raw material, add nylon yarn class chemical fibre reinforcing material.
Described binder is phenolic resin glue, urea-formaldehyde resin adhesive, epoxide-resin glue, polyisocyanate fat latex.
The method of above-mentioned cambered surface and spherical sound box moulding is characterized in that base-material and binder mixed in proportion and mixes the back thoroughly and inject the compressed moulding of mould; Install other assemblies of casing after the demoulding again.
Compression forming comprises adopts cold compression moulding or hot compression moulding.
Advantage of the present invention is: owing to adopt mould molding, can be made into various special-shaped audio amplifiers as required, need not to engrave and mill processing, and product precision height, the moulding radian is big, and cost of manufacture is low, the minimizing dust pollution, the smooth no scrimp of plate face after the moulding.Method of the present invention also can be used for the production of special-shaped furniture.
