The position, which is corresponding to the placing hole, of the lower shell is provided with a position-specifying hole which is used for positioning the loudspeaker. One side, which is corresponding to the placing hole, of the upper shell is provided with an upper sound propagation channel. One side, which is corresponding to the position-specifying hole, of the lower shell is provided with a lower sound propagation channel which matches the upper sound propagation channel. The sound box shell is reasonable in design, simple in structure, small and exquisite in size, light and convenient to carry, convenient to transport and easy to manufacture.

Description

Casing of loudspeaker box
Technical field
The utility model relates to the audio amplifier field, is specifically related to casing of loudspeaker box.
Background technology
At present, allegro life makes people recognize that suitable amusement is very effective to the pressure of alleviating life.Therefore the abstract the recreational consumption of family is at rapid growth, and digitized stereo set is also more and more universal, and using the most general stereo set is mainly audio amplifier, for meeting different occasions, and the demand of different crowd, the function that audio amplifier possesses is also more and more.In prior art, the volume of audio amplifier is all huger, the carrying effort, be subject to the restriction of various conditions, can not meet people's needs, and a lot of sound-box device is because the internal structure design is reasonable not, affect the sound transmission of loud speaker, thereby affect the result of broadcast of audio amplifier.
Summary of the invention
Technical problem to be solved in the utility model is to provide casing of loudspeaker box, reasonable in design, simple in structure, and volume is small and exquisite, carrying portable, and convenient in carrying, easy to manufacture.
For solving above-mentioned existing technical problem, the utility model adopts following scheme: casing of loudspeaker box, comprise upper casing and lower casing, described upper casing is provided with for placing the putting hole of loud speaker, on described lower casing, the position of corresponding putting hole is provided with the spacing hole that loud speaker is positioned, on described upper casing, a side of corresponding putting hole is provided with the sound transmission passage, and on described lower casing, a side of corresponding spacing hole is provided with the lower sound transmission passage be complementary with upper sound transmission passage.
As preferably, described upper sound transmission passage comprises the sound groove and is connected the upper curved channel arranged with the sound groove.By adopting this set, simple in structure, reasonable in design, easily manufactured.
As preferably, described lower sound transmission passage comprises voice coil loudspeaker voice coil and is connected the arc lower passage arranged with voice coil loudspeaker voice coil.By adopting this set, simple in structure, reasonable in design, easily manufactured.
As preferably, described upper casing is provided with some fixedly projections, the fixing hole that described lower casing is provided with fixedly projection is complementary.By adopting this set, can conveniently upper casing and lower casing be fixed, upper casing is coordinated more closely with lower casing.
As preferably, be respectively equipped with some fixing holes on the edge of described upper casing and lower casing.By adopting this set, can further to upper casing and lower casing, be fixed operation by adopting screw, make overall structure more stable.
Beneficial effect:
The utility model adopts technique scheme that casing of loudspeaker box is provided, and has made up the deficiencies in the prior art, has reduced volume, has alleviated weight, has improved the audio of audio amplifier, and reasonable in design, simple in structure, volume is small and exquisite, carrying portable, and convenient in carrying, easy to manufacture.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, casing of loudspeaker box, comprise upper casing 1 and lower casing 2, described upper casing 1 is provided with the putting hole 3 for placing loud speaker, on described lower casing 2, the position of corresponding putting hole 3 is provided with the spacing hole 4 that loud speaker is positioned, on described upper casing 1, a side of corresponding putting hole 3 is provided with sound transmission passage 5, and on described lower casing 2, a side of corresponding spacing hole 4 is provided with the lower sound transmission passage 6 be complementary with upper sound transmission passage 5.Described upper sound transmission passage 5 comprises sound groove 51 and is connected the upper curved channel 52 arranged with sound groove 51.Described lower sound transmission passage 6 comprises voice coil loudspeaker voice coil 61 and is connected the arc lower passage 62 arranged with voice coil loudspeaker voice coil 61.Described upper casing 1 is provided with some fixedly projections 7, the fixing hole 8 that described lower casing 2 is provided with fixedly projection 7 is complementary.Be respectively equipped with some fixing holes 9 on the edge of described upper casing 1 and lower casing 2.
During real work, in putting hole 3 by the loud speaker fixed placement on upper casing, the 4 pairs of loud speakers of spacing hole that are arranged on lower casing have good position-limiting action, the loud speaker sounding passes in sound groove 1 and voice coil loudspeaker voice coil 61, then advanced upper curved channel 52 and 62 propagation of arc lower passage, upper casing 1 is provided with some fixedly projections 7, the fixing hole 8 that described lower casing 2 is provided with fixedly projection 7 is complementary, make overall structure stable, reach better working effect.Made up the deficiencies in the prior art, reduced volume, alleviated weight, improved the audio of audio amplifier, reasonable in design, simple in structure, volume is small and exquisite, carrying portable, and convenient in carrying, easy to manufacture.
Specific embodiment described herein is only to the explanation for example of the utility model spirit, the utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
