Abstract
The audio amplifier is composed of case body and loudspeakers fixed in the case body, and features that its case body is made of ceramics for pure sound timbre and low cost.
Description
The present invention relates to a kind of stereo set, especially a kind of audio amplifier.
The casing of existing audio amplifier all is wood materials, fiber board etc., because wood materials hardness intensity is lower, there is the weakness that lacks rigidity in the splicing of casing always, yielding, cracking, and make wooden casing be easy to generate that case shakes and sound coloration etc. sheltered disease, in addition, present sound box all adopts squared design, makes loud speaker produce certain post ripple distortion, and timber price raises up in addition, product cost is increased, cause the difficulty in the sale.
The purpose of this invention is to provide strong, the on-deformable audio amplifier of a kind of gear housing rigidity.
Technical solution of the present invention is: be made up of casing, the loud speaker that is fixed in the casing, it is characterized in that: the material of described casing is for making pottery or porcelain.
Utilize existing potting or technology in producing porcelain, make the casing one-shot forming.
The present invention compared with prior art, because the casing of audio amplifier is the higher ceramic material of hardness, and once-forming, there is not splicing, therefore the present invention has following advantage: 1 has favorable rigidity, eliminated that case shakes and the sound coloration phenomenon, can allow the people of music appreciating obtain totally, real sound reproduction, sound technique is further improved; Simultaneously ancient ceramic process is combined with the sound technique of modern high technology; 2, ceramic loudspeaker box is with low cost, has reduced the price of product, makes pure music enter more people's life; 3, the increment effect that has product titled with blue and white, powder enamel, hold a memorial ceremony for the audio amplifier that potting, technology in producing porcelain such as red, colored drawing handle, itself promptly is a gem of art that has reserve value; If the profile of 4 casings is cylindric, ellipticity etc. also can be eliminated the distortion of post ripple effectively, further improve tonequality.
Below in conjunction with accompanying drawing the present invention is further described:
Fig. 1 is A-A cutaway view shown in Figure 2;
Fig. 2 is the principal part view of casing among the present invention.
As shown in the figure: utilize traditional potting or technology in producing porcelain, promptly base, box out, go up color, fire etc., make the casing once-forming.On casing, leave speaker hole 1,2, wiring hole 3 and curve bass reflex pipe 4 during base.In order to lower the center of gravity, the bottom of casing can thicken, and gets final product for 20～30 millimeters than the other parts thickening.With loud speaker, after terminal box installs, can obtain a ceramic loudspeaker box.
