Abstract
A soundbox mesh enclosure comprises through holes and blind holes, wherein the through holes are distributed at the front part of a diffuser; the blind holes are divided into front holes and rear holes, wherein the front holes are connected with the conical rear holes. On the mesh enclosure, the visual color of a through hole distribution area is similar to that of a blind hole distribution area, so the whole mesh enclosure has no obvious layering, and is added with an aesthetic feeling. A mould for manufacturing the soundbox mesh enclosure comprises a front template and a rear template, wherein through hole projection columns and blind hole projection columns are arranged on the front template; and the blind hole projection columns are divided into front columns and rear columns which are connected with each other, and the front columns are conical. In the produced mesh enclosure, the visual color of the through hole distribution area is similar to that of the blind hole distribution area, so the whole mesh enclosure does not have obvious layering, and is added with an aesthetic feeling.
Description
Technical field
The utility model relates to stereo set, especially a kind of audio amplifier guard and mfg. moulding die thereof of plastic cement.
Background technology
At present, 3C Product is in the middle of development at full speed, as computer, mobile phone, TV, Digital A etc., the speed that causes accelerating model change with rapid changepl. never-ending changes and improvements of 3C Product.In today of social high development, people also increase to the pursuit of life, and for the audio amplifier in the video and audio product, people not only pay attention to the performance of product, for the appearance design of product, higher requirement have been arranged also.As shown in Figure 1, in the prior art, audio amplifier generally comprises casing, frequency divider, loud speaker, and the casing front is provided with guard, because the requirement of loud speaker sounding, have many through holes and closed pore on the guard, human eye looks that for the zone that is distributed with through hole, sight line can directly be passed through hole and be entered into audio amplifier inside, because audio amplifier internal light deficiency, the guard color of throughhole portions is generally deep; For the zone that is distributed with closed pore, sight line can only be seen the bottom of closed pore, because the closed pore bottom area is bigger, human eye looks can see the folding line that the bottom surface is round, and visual color that should the zone is shallow with respect to via regions, makes whole guard layering sensation obviously, the shortcoming aesthetic feeling.
Summary of the invention
One of technical problem to be solved in the utility model provides a kind of audio amplifier guard, and the visual color of via regions is close with the closed pore zone on the guard, makes whole guard layering feel not obvious, has increased the aesthetic feeling of audio amplifier guard.
Two of technical problem to be solved in the utility model provides a kind of mfg. moulding die of audio amplifier guard, in the produced guard, the visual color of via regions is close with the closed pore zone, makes whole guard layering feel not obvious, has increased the aesthetic feeling of audio amplifier guard.
For one of solving the problems of the technologies described above, the technical solution of the utility model is: a kind of audio amplifier guard, comprise through hole, closed pore, and described through hole is distributed in the place ahead of diffuser; Described closed pore is divided into preceding hole and metapore, and preceding hole and metapore join, and it is conical that described metapore is.Human eye looks that for the zone that is distributed with through hole on the guard, sight line can directly be passed through hole and be entered into audio amplifier inside, because audio amplifier internal light deficiency, the visual color of via regions is generally deep on the guard; For the zone that is distributed with closed pore on the guard, sight line can only be seen the bottom of closed pore, because the closed pore bottom pools a bit, and visual color and via regions that should the zone be close, human eye looks does not have tangible folding line, make whole guard via regions and closed pore region subdivision feel not obvious, increased the aesthetic feeling of audio amplifier guard.
As improvement, described preceding hole is the through hole of taper type, and the preceding hole of taper type and conical metapore transition are more smooth and easy.
As improvement, described preceding hole and metapore joint are circular arc, make preceding hole and metapore joint not have tangible folding line.
For solve the problems of the technologies described above two, the technical solution of the utility model is: a kind of mould that is used to make the audio amplifier guard, described mould comprises front template, rear pattern plate, described front template is provided with through hole projection, closed pore projection; Described closed pore projection is divided into front pillar and rear pillar, and front pillar and rear pillar join, and it is conical that described front pillar is.Utilize the closed pore of the produced guard of this mould to be divided into preceding hole and metapore, preceding hole and metapore join, and it is conical that metapore is.Human eye looks that for the zone that is distributed with through hole on the guard, sight line can directly be passed through hole and be entered into audio amplifier inside, because audio amplifier internal light deficiency, the color of via regions is generally deep on the guard; For the zone that is distributed with closed pore on the guard, sight line can only be seen the bottom of closed pore, because the closed pore bottom pools a bit, human eye looks does not have tangible folding line, make whole guard via regions and closed pore region subdivision feel not obvious, increased the aesthetic feeling of audio amplifier guard.
As improvement, described rear pillar is taper type, and the rear pillar of taper type and conical front pillar transition are more smooth and easy, and in the produced guard closed pore, the preceding hole of taper type and conical metapore transition are more smooth and easy.
Be circular arc as improving described front pillar and rear pillar joint, in the produced guard closed pore, preceding hole and metapore joint are circular arc, make preceding hole and metapore joint not have tangible folding line.
The beneficial effect that the utility model is compared with prior art brought is:
Closed pore on the guard is divided into the preceding hole and the conical metapore of taper type, and the two interconnects, and the junction is circular arc, and human eye looks that for the zone that is distributed with through hole on the guard, sight line can directly be passed through hole and be entered into audio amplifier inside; For the zone that is distributed with closed pore on the guard, sight line can only be seen the conical lower section of closed pore, because the closed pore bottom pools a bit, human eye looks does not have tangible folding line, the visual color of via regions is close with the closed pore zone on the guard, make whole guard layering feel not obvious, increased the aesthetic feeling of audio amplifier guard.

Embodiment
The utility model is described in further detail below in conjunction with Figure of description.
Embodiment 1
Shown in Fig. 2 to 4, a kind of audio amplifier guard comprises through hole 4, closed pore 5, and described through hole 4 is distributed in diffuser (not indicating) the place ahead.Described closed pore 5 is divided into the preceding hole 51 and the conical metapore 52 of taper type, and preceding hole and metapore 52 join, and preceding hole 51 is circular arc with metapore 52 joints 53, makes that the transition between preceding hole 51 and the metapore 52 does not have tangible folding line.Human eye looks that for the zone 2 that is distributed with through hole on the guard, sight line can directly be passed through hole 4 and be entered into audio amplifier inside, because audio amplifier internal light deficiency, the visual color of via regions 2 is generally deep on the guard; For the zone 3 that is distributed with closed pore on the guard, sight line can only be seen the conical lower section of closed pore 5, because closed pore 5 bottoms pool a bit, human eye looks does not have tangible folding line, and visual color that should the zone is close with via regions 2, make zone 3 layerings of whole guard through hole area 2 territories and closed pore feel not obvious, increased the aesthetic feeling of audio amplifier guard.
