Description

Sound resonator of stone material

The utility model relates to a kind of audio amplifier, and its housing is to be made with the building stones sheet material.

In the prior art, voice box casing is made by wood materials or plastics mostly, its advantage is with low cost, be easy to make, but raising along with people's quality of life, tonequality to electro-acoustic product should have further requirement mutually, make sound box by wooden thing or plastics, because the light weight of material, density is little, so the audio amplifier of making easily produces dissonances such as noise, thereby influence the quality of electro-acoustic product, (notification number: 2109033) disclose a kind of its housing and back shroud and annotated the audio amplifier that forms by magnesium oxychloride concrete material mould, its advantage is: it has good acoustic characteristic to Chinese patent " magnesium oxychloride concrete audio amplifier ", and technology is simple, cost is low.

The purpose of this utility model is: propose a kind of sound resonator of stone material that is made of its casing building stones sheet material.

The realization the technical solution of the utility model is as follows:

It comprises sound box 1, loud speaker 2, phase-reversing tube 3, frequency divider 6, wherein has damping material 4 on the inwall of sound box 1, and also is provided with binding post 5 on the box body wall, and its architectural feature is:

1) described sound box is to be made of the building stones plate, and the thickness of this plate is the 15-25 millimeter, and the cross section of plate is trapezoidal faces, and adjacent plate is by bonding the forming in trapezoidal inclined-plane of its termination,

2) corner in described sound box is provided with reinforcing strip 7, and it can further tighten up adjacent casing plate,

3) on described sound box, on the box body wall corresponding to fixedly loud speaker, phase-reversing tube position, be provided with stepped hole, preset nut 8 is housed in this stepped hole, described loud speaker and phase-reversing tube are fixed by screw and this preset nut and sound box.

The utility model has the advantages that:

1) sound resonator of stone material can greatly reduce the resonance disturbing wave that common audio amplifier is light because of tank material, density is not enough to be caused,

2) sound that it broadcasted, tonequality is pure, totally plentiful, range is broad, fidelity good, and sound has good group's sense and third dimension, especially is suitable for allegro melody and plays.

Below in conjunction with accompanying drawing the utility model is elaborated:

Fig. 1 is the structural representation after the utility model is cut open,

Fig. 2 is a panel schematic diagram of the present utility model,

Fig. 3 is the casing described in the utility model with reinforcing strip and is attached to structural representation after damping material on the box body wall combines,

Fig. 4 is the front view that constitutes the stone material plate of casing in the utility model,

Fig. 5 is the left view of Fig. 4 in the utility model,

Fig. 6 is the vertical view of Fig. 4 in the utility model,

Fig. 7 is the building stones plate of positions of panels in the utility model and schematic diagram after preset nut 8 combines,

As shown in Figure 1: the utility model is made up of sound box 1, loud speaker 2, phase-reversing tube 3, frequency divider 6, wherein has damping material 4 on the inwall of sound box 1, and also be provided with binding post 5 on the box body wall, described loud speaker is two, and place the upper-lower position place of sound box, its design feature is as follows:

1) described sound box is to be made of the marble plate, the thickness of this plate can be chosen between the 15--25 millimeter according to the audio amplifier size, the cross section of plate is trapezoidal faces, as Fig. 4, Fig. 5, shown in Figure 6, adjacent plate is by bonding the forming in trapezoidal inclined-plane of its termination, the oblique angle of its trapezoidal faces is 45 degree

2) each corner in described sound box is equipped with batten roll 7, and this batten roll can further cling adjacent casing plate by sticky object,

3) on the marble plate on the described sound box panel, corresponding to the fixing position of loud speaker, phase-reversing tube, be drilled with stepped hole in advance, is fixed with preset nut 8 with adhering liquid in this stepped hole, described loud speaker and phase-reversing tube are fixed by screw and this preset nut and sound box panel.
