Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
- 3 are please referred to Fig.1, the present invention provides a kind of technical solution：A kind of loudspeaker cover body of the exhibition room with sound amplification function,
Including extension board 1, sliding block 4 and panel seat 9, the rear of extension board 1 is equipped with shell 2, and shell 2 is internally provided with inner casing 3, outside
The inside of shell 2 is in engraved structure shape, and the inner wall of shell 2 is in contact with the outer wall of inner casing 3, passes through the shell at 1 rear of extension board
2 so that shell 2 can be extended through inner casing 3, and the length of shell 2 is promoted to be expanded, so that the loudspeaker that length differs
It can be wrapped up by shell 2 so that loudspeaker are integrally placed in shell 2, and sliding block 4 is installed on the interior surface of shell 2, and sliding block 4
External stability has sliding slot 5, and sliding block 4 is set as rectangular structure, and sliding block 4 is run through by threaded post 6, while sliding block 4 is uniformly distributed
In the interior surface of shell 2, pass through the sliding block 4 inside shell 2 so that the threaded post 6 through sliding block 4 can be by sliding block 4 in cunning
It is moved in slot 5, so that the rubber slab 8 that the loudspeaker of different length can be connect in shell 2 with threaded post 6 is connect
It touches, sliding block 4 is internally connected with threaded post 6, and side of the threaded post 6 far from 2 central shaft of shell is equipped with nut 7, and nut 7
It is connected with rubber slab 8 close to the side of shell 2 central shaft, the longitudinal central axis of the lateral central axes of rubber slab 8 perpendicular to threaded post 6
To, and rubber slab 8 is in rotational structure by threaded post 6 and shell 2, passes through the rubber slab 8 being connect with threaded post 6 so that rubber
Plate 8 can squeeze loudspeaker by the movement of threaded post 6, and loudspeaker is promoted to be fixed in shell 2 so that loudspeaker will not be from
Fall off inside shell 2, while by rubber slab 8, but also rubber slab 8 is during squeezing loudspeaker, to loudspeaker into
A kind of protection of row, panel seat 9 is installed on the rear of shell 2, and is fixed with circular hole 10 at left and right sides of the inside of panel seat 9, extension board 1
Inner wall is provided with spiral layers 11, and the length of spiral layers 11 is less than the length of extension board 1, and the outer wall of spiral layers 11 and extension board 1
Inner wall be in contact, by the spiral layers 11 inside extension board 1, can make spiral layers 11 to by air-flow generate a kind of spiral
The effect of acceleration promotes spiral layers 11 to have the function of that air-flow can be enhanced so that the sound that loudspeaker generate is by the work of spiral layers 11
Under, there is stronger penetrability, to which the sound for making loudspeaker generate is enhanced, loudspeaker can be influenced by promoting loudspeaker cover body to have
The effect of volume, panel seat 9 is equipped with bolt 12 inside the side of 2 central shaft of shell, and the front of bolt 12 is provided with wind
Fan 13, the central shaft of fan 13 matches with the central shaft of shell 2, and fan 13 is connected by panel seat 9 with shell 2, is passed through
Fan 13 on panel seat 9, can make the air inside shell 2 have the effect of strenuous exercise, promote the air-flow moved by loudspeaker
Heat is taken away caused by work, so that loudspeaker cover body has the function of heat dissipation, is fixed with inside the front of shell 2 or so
Wedge slot 14, and the inside of wedge slot 14 is equipped with voussoir 15.
Operation principle：Use the loudspeaker cover body with sound amplification function first by inner casing 3 out of shell 2 this kind of exhibition room
Portion pulls out so that the length of shell 2 is extended, and promotes the loudspeaker of different length that can also be placed in shell 2, by sliding block 4
It is moved by sliding slot 5 so that rubber slab 8 is corresponding with the position of loudspeaker, and threaded post 6 is turned so that rubber slab 8
Loudspeaker are squeezed, loudspeaker is promoted to be fixed in shell 2 so that loudspeaker will not fall off inside shell 2, while pass through rubber
Offset plate 8 carries out a kind of protection but also rubber slab 8 is during squeezing loudspeaker to loudspeaker, by 7 turns of nut
It is dynamic so that nut 7 is moved to the outer wall of shell 2, sliding when nut 7 contacts friction with 2 outer wall of shell by threaded post 6 to be increased
Block 4 will be fixed in sliding slot 5, and to promote sliding block 4 not shake, panel seat 9 is fixed on corresponding position by circular hole 10
On so that panel seat 9 has stronger stability, and it is not in the case where falling, to work as loudspeaker to promote the loudspeaker being placed in shell 2
When being worked, sound that loudspeaker generate will by spiral layers 11, promote spiral layers 11 to by sound generate a kind of spiral
The effect of acceleration so that spiral layers 11 have the function of that sound can be enhanced, stronger to promote the sound that loudspeaker generate to have
Penetrability promotes loudspeaker cover body to have the function of that horn volume can be influenced, together so that the sound that loudspeaker generate is enhanced
When fan 13 is opened so that the heat that generates is blown by fan 13 when loudspeaker work, and heat is promoted quickly to be vaporized, to
The quality for not influencing loudspeaker takes out voussoir 15 from wedge slot 14 when loudspeaker cover body needs dismounting so that shell 2 and extension board 1
The use process that entire exhibition room uses the loudspeaker cover body with sound amplification function is completed in separation like this.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
Understanding without departing from the principles and spirit of the present invention can carry out these embodiments a variety of variations, modification, replace
And modification, the scope of the present invention is defined by the appended.
