Abstract

The utility model discloses a casing structure of sound box, wherein, the casing of the sound box is just one section of the casing sections. For the casing of the sound box is just one section of the casing sections, one can acquire different lengths in the one-time molded casing section when in producing the sound box casings in the same specification and different heights, thus one mold is applicable for a plurality of types. Compared with the traditional products, the utility model effectively reduces the cost of the mold. For sound boxes requiring the same vocal quality, the fabricating technique is simpler and the weigh is lighter, for the sealing property of the utility model is better than that of wooden sound boxes.

Description

A kind of voice box casing structure

Technical field

The utility model relates to a kind of stereo set, is meant a kind of voice box casing structure especially.

Background technology

Common wooden acoustic box housing is to be assembled by sheet material, for reaching good acoustical quality, then forms the sheet material and the sealing between the sheet material of voice box casing will get well, so it is had relatively high expectations on manufacture craft; And the voice box casing of injection mo(u)lding, its mould of different voice box casings is promptly inequality, even if the audio amplifier of same moulding, because the difference of its height still needs different moulds, so its production cost is higher.

The utility model content

The purpose of this utility model provides a kind of at same moulding and the voice box casing structure that the voice box casing of differing heights can significantly reduce cost.

For achieving the above object, solution of the present utility model is: a kind of voice box casing structure, wherein voice box casing is in the shell section material one section, is equipped with the hole of setting loud speaker in appropriate location, housing front side.

Described voice box casing is aluminium matter or plastic material.

After adopting such scheme, because at same moulding and the voice box casing of differing heights can intercept different length as required in the shell section material of disposal molding, like this, a mould is applicable a plurality of machine, commonly uses the cost that product can effectively reduce mould relatively; At the audio amplifier of same tonequality requirement, because the voice box casing seam of producing is few, sealing is good than wooden acoustic box, and is then simple than wooden acoustic box on manufacture craft, and the volume of product is little, in light weight in addition.

Fig. 6 is the enforcement illustration (two) of another moulding of the utility model.

Embodiment

As shown in Figure 1, 2, voice box casing structure of the present utility model, its voice box casing 11 is a section in the shell section material 1, and shell section material 1 forms aluminium ingot or the disposable stretching of plastics by a mould on a board, after highly intercepting a section of shell section material 1 according to required voice box casing 11, form a casing of loudspeaker box in conjunction with upper and lower and

protecgulum

2,3 again, loud speaker can be by embedding in punching back, the appropriate location, front side of housing 11.This casing housing 1 may be molded to square, because the casing of loudspeaker box seam of producing is few, at the audio amplifier that same tonequality requires, sealing is good than wooden acoustic box, and is then simple than wooden acoustic box on manufacture craft, and product is in light weight.

Cooperate shown in Figure 3ly, this audio amplifier is identical with the audio amplifier moulding shown in Fig. 2, and just they are highly different, then the housing 1 of its audio amplifier just intercepts from shell section material and gets final product, and do not need other moulding, then reduced the quantity of establishing mould in the product in addition, thereby effectively reduced the die sinking cost as commonly using.

Shown in Fig. 4,5,6, this casing 1 also may be molded to other shape.

Claims

1, a kind of voice box casing structure is characterized in that: voice box casing is a section in the shell section material, is equipped with the hole of setting loud speaker in appropriate location, housing front side.

2, a kind of voice box casing structure as claimed in claim 1, it is characterized in that: voice box casing is aluminium matter or plastic material.
