Abstract
Sound guide tube audio amplifier after a kind of, comprise sound box, bass horn and loudspeaker, described loudspeaker is located at the top of the cavity of sound box, described bass horn is located at the bottom of the cavity of sound box, sound guide tube is provided with in the cavity of sound box, described sound guide tube is located at the top of the cavity of sound box and sound guide tube is in the rear end of loudspeaker, sound guide tube the cavity of sound box is in communication with the outside and the opening of sound guide tube backwards.Because sound guide tube is located at the top of the cavity of sound box and sound guide tube is in the rear end of loudspeaker, the sound wave sent on rear side of bass horn after being derived by sound guide tube after first mixing in the cavity of sound box with the sound wave sent on rear side of loudspeaker again with on front side of bass horn with loudspeaker on front side of the dual effect mixing audio to strengthen audio amplifier of the sound wave that sends.
Description
Technical field
The utility model relates to audio amplifier clothing arts, is specifically related to a kind of rear sound guide tube audio amplifier.
Background technology
Usually sound guide tube can be provided with in the casing of audio amplifier in existing audio amplifier; the effect of sound guide tube mixes mutually with the sound wave sent on front side of loudspeaker after being spread out of by the sound wave sent on rear side of loudspeaker; thus strengthen the audio of audio amplifier; then because the position that sound guide tube is located in casing is not generally fixed; the sound wave of deriving can not well mix with the sound wave sent on front side of loudspeaker mutually, makes the DeGrain of the audio of enhancing audio amplifier.
Summary of the invention
The technical problems to be solved in the utility model is to provide and a kind ofly can will derives the rear sound guide tube audio amplifier that mix the effect of audio to strengthen audio amplifier dual with the sound wave that sends on front side of bass horn and on front side of loudspeaker after the sound wave sent on rear side of bass horn and on rear side of loudspeaker mixing again.
In order to solve the problems of the technologies described above, the utility model comprises sound box, bass horn and loudspeaker, described loudspeaker is located at the top of the cavity of sound box, described bass horn is located at the bottom of the cavity of sound box, sound guide tube is provided with in the cavity of sound box, described sound guide tube is located at the top of the cavity of sound box and sound guide tube is in the rear end of loudspeaker, sound guide tube the cavity of sound box is in communication with the outside and the opening of sound guide tube backwards.Because sound guide tube is located at the top of the cavity of sound box and sound guide tube is in the rear end of loudspeaker, the sound wave sent on rear side of bass horn after being derived by sound guide tube after first mixing in the cavity of sound box with the sound wave sent on rear side of loudspeaker again with on front side of bass horn with loudspeaker on front side of the dual effect mixing audio to strengthen audio amplifier of the sound wave that sends.
As further improvement of the utility model, described sound box can comprise audio amplifier upper cover, audio amplifier lower cover, Loudspeaker front cover, audio amplifier bonnet and guard, bass horn and loudspeaker are arranged on Loudspeaker front cover, sound guide tube is arranged on audio amplifier bonnet, fastening part is respectively equipped with at audio amplifier upper cover place and audio amplifier lower cover place, described guard is provided with the groove that can coordinate with fastening part, and guard is located between audio amplifier upper cover and audio amplifier lower cover by fastening part and groove fit.
As further improvement of the utility model, the quantity of described sound guide tube can be two, and the cross section of the pore of described sound guide tube is rectangle.
As further improvement of the utility model, two brace rods can be provided with between audio amplifier upper cover and audio amplifier lower cover, the structural strength of audio amplifier can be strengthened like this.
As further improvement of the utility model, can be provided with the installing hole of indent in the bottom of sound box, such audio amplifier can be connected with mounting column by installing hole, to adapt to different environments for use.
In sum, the utility model has the advantages that and can will derive again the effect that mix audio to strengthen audio amplifier dual with the sound wave that sends on front side of bass horn and on front side of loudspeaker after the sound wave sent on rear side of bass horn and on rear side of loudspeaker mixing.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Fig. 1 is the structural representation that the utility model removes side plate and guard.
Fig. 2 is cutaway view of the present utility model.
Embodiment
By shown in Fig. 1 to Fig. 2, the utility model comprises sound box, bass horn 1 and loudspeaker 2, described sound box comprises audio amplifier upper cover 3, audio amplifier lower cover 4, Loudspeaker front cover 5, audio amplifier bonnet 6 and guard 7, fastening part 8 is respectively equipped with at audio amplifier upper cover 3 place and audio amplifier lower cover 4 place, described guard 7 is provided with the groove 9 that can coordinate with fastening part 8, guard 7 to be coordinated with groove 9 by fastening part 8 and is located between audio amplifier upper cover 3 and audio amplifier lower cover 4, described loudspeaker 2 is located at the top of the cavity of sound box and is arranged on Loudspeaker front cover 5, described bass horn 1 is located at the bottom of the cavity of sound box and is arranged on Loudspeaker front cover 5, sound guide tube 10 is provided with in the cavity of sound box, sound guide tube 10 is arranged on audio amplifier bonnet 6, described sound guide tube 10 is located at the top of the cavity of sound box and sound guide tube 10 is in the rear end of loudspeaker 2, sound guide tube 10 cavity of sound box is in communication with the outside and the opening of sound guide tube 10 backwards, the quantity of described sound guide tube 10 is two, the cross section of the pore of described sound guide tube 10 is rectangle, two brace rods 11 are provided with between audio amplifier upper cover 3 and audio amplifier lower cover 4, the installing hole 12 of indent is provided with in the bottom of sound box.Because sound guide tube 10 is located at the top of the cavity of sound box and sound guide tube 10 is in the rear end of loudspeaker 2, the sound wave sent on rear side of bass horn 1 after being derived by sound guide tube 10 after first mixing in the cavity of sound box with the sound wave sent on rear side of loudspeaker 2 again with on front side of bass horn 1 with loudspeaker 2 on front side of the dual effect mixing audio to strengthen audio amplifier of the sound wave that sends.Brace rod 11 can strengthen the structural strength of audio amplifier, and audio amplifier can be connected with mounting column by installing hole 12, to adapt to different environments for use.
