Accompanying drawing explanation
Below with accompanying drawing, the present invention is further detailed, but the embodiment in accompanying drawing is not constituted this
Bright any restriction.
Fig. 1 is the structural representation of the present invention.
Include in FIG:
1 sound box 2 metal goes out soundboard
21 sender 3 flexible glue pneumatophores
Flexible glue layer inside flexible glue layer 32 outside 31
33 inflating cells 4 control handles.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention will be described.
As it is shown in figure 1, the extendible loudspeaker box structure in a kind of sound chamber, including sound box 1, the inside of sound box 1 becomes
Type has casing containing cavity, is embedded with sound box bodies and the PCB control circuit board electrically connected with external power source in casing containing cavity,
PCB control circuit board electrically connects with sound box bodies, and the front of sound box 1 is equiped with metal and goes out soundboard 2, and metal goes out soundboard 2 and offers
Having the sender 21 being distributed in uniform intervals and connecting with casing containing cavity, the front of sound box bodies is just going out soundboard 2 to metal.
Further, the back side panel of sound box 1 offers backward opening and the back side panel that connects with casing containing cavity leads to
Hole, the rear end side of sound box 1 is equiped with the edge part of flexible glue pneumatophore 3, the edge part of flexible glue pneumatophore 3 and back side panel through hole
Connecting, flexible glue pneumatophore 3 includes outside flexible glue layer 31, is positioned at the inner side flexible glue layer 32 of flexible glue layer 31 side, outside, outside
The edge part of the edge part of flexible glue layer 31 and inner side flexible glue layer 32 be tightly connected and outside flexible glue layer 31 and inner side flexible glue layer 32 it
Between form inflating cells 33, outside flexible glue layer 31 offers the air filling and exhausting hole connected with inflating cells 33.
Need to be explained further, the outside flexible glue layer 31 of the present invention, inner side flexible glue layer 32 can be respectively adopted silica gel material to be prepared
Form, i.e. the outside flexible glue layer 31 of the present invention, inner side flexible glue layer 32 is respectively layer of silica gel；Certainly, above-mentioned material be not intended that right
