The present invention technical solution be：A kind of audio amplifier, including box-like body, the box-like body leading flank are provided with low
Sound loudspeaker installing port and high pitch loudspeaker installing port, woofer is installed in the woofer installing port, it is described
High pitch loudspeaker is installed in high pitch loudspeaker installing port, the rearmost of box-like body back side bottom and bottom surface formed with
Opening, the box-like body is interior to be connected formed with sound channel, the front side of the sound channel with woofer installing port,
Sound channel rear side and opening in communication.
Further, above-mentioned audio amplifier, wherein：The sound channel includes the first bending section, straightway and the second bending section,
The first bending section front end is connected with woofer installing port, and the straightway front end is connected with the first bending section rear end
Logical, the second bending section front end is connected siphunculus with straightway rear end, second bending section and opening in communication.
Further, above-mentioned audio amplifier, wherein：The woofer installing port is to the part of the first bending section, passage
Internal diameter is gradually reduced.
Further, above-mentioned audio amplifier, wherein：The area of the last end section of the bending section of sound channel first is low
The 70% of sound loudspeaker vibration area.
Further, above-mentioned audio amplifier, wherein：It is logical by connecting between the high pitch loudspeaker installing port and sound channel
Road is connected, and the interface channel width is 3 ~ 5mm.
Further, above-mentioned audio amplifier, wherein：The box-like body is oblique, with ground into 30 ~ 60 ° of inclination angles.
Yet further, above-mentioned audio amplifier, wherein：The opening upper edge is horizontal by 30 ~ 60 ° of inclination angles.
The prominent substantive distinguishing features of the present invention and significant technological progress are mainly reflected in：The opening of audio amplifier of the present invention
It is connected with sound channel, and is open using bottom surface and box-like body hypsokinesis angle so as to form a very big bugle of area
Shape, it, which is acted on, can be analogous to bugle, therefore no longer need to install bugle in box-like body.And it is open and is located at casing dorsal part bottom
Portion, after acoustic radiating comes out, utilize leaned against metope and bottom surface can be by sound reflection, and sound is from all directions
Radiate, with more third dimension, box-like body is provided with woofer and high pitch loudspeaker, sound frequency amplitude broad.
Brief description of the drawings
Fig. 1 is audio amplifier sectional view；
Fig. 2 is bass conspectus in audio amplifier.
In figure, the implication of each reference is：1-sound channel, the 11-the first bending section, 12-straightway, 13-the
Two bending sections, 21-straightway device, 2-wiring board installing port, 3-opening, 4-woofer installing port, 5-tweeter
Device installing port, 6-interface channel, 7-woofer, 8-high pitch loudspeaker.
Embodiment
Below in conjunction with accompanying drawing, the embodiment of the present invention is described in further detail, so that technical solution of the present invention is more
It should be readily appreciated that and grasp.
As shown in figure 1, audio amplifier of the present invention includes box-like body, box-like body is oblique, with ground into 30 ~ 60 ° of inclination angles,
Box-like body leading flank is provided with woofer installing port 4 and high pitch loudspeaker installing port 5, and the box-like body back side is provided with wiring board
Installing port 7, accordingly, woofer 7 is installed in woofer installing port 4, installed in high pitch loudspeaker installing port 5
Have high pitch loudspeaker 8, wiring board be installed in wiring board installing port 2, box-like body back side bottom and bottom surface it is last square
Into there is opening 3,3 upper edges of opening are horizontal by 30 ~ 60 ° of inclination angles.Formed with sound channel 1, sound channel 1 in box-like body
Front side be connected with woofer installing port 4, rear side is connected with opening 3.High pitch loudspeaker installing port 5 leads to sound
It is connected between road 1 by interface channel 6.
Sound channel 1 includes the first bending section 11, the bending section 13 of straightway 12 and second, the front end of the first bending section 11 and low
Sound loudspeaker installing port 4 is connected, and the front end of straightway 12 is connected with the rear end of the first bending section 11, the front end of the second bending section 12 and
The rear end of straightway 12 is connected siphunculus, and the second bending section 12 is connected with opening 3.The bending section of woofer installing port 4 to the first
11 part, channel internal diameter are gradually reduced.
By above description, opening 3 is connected with sound channel 1, and opening 3 utilizes bottom surface and box-like body hypsokinesis
Angle is so as to forming the very big bugle shape of an area.The compound action of opening 3 and sound channel 1 can be analogous to bugle, therefore
No longer need that bugle is installed in box-like body.And opening 3 is located at casing dorsal part bottom, after acoustic radiating comes out, institute is utilized
The metope leaned against and bottom surface can be by sound reflections, and sound is radiated from all directions, with more third dimension.Casing
Woofer 7 and high pitch loudspeaker 8, sound frequency amplitude broad are provided with body.
Specifically, sound channel 1 includes the first bending section and the second bending section, when ensureing bass sounding, air gas
Stream can free in and out, and can sponge noise caused by air draught in pipe.The length of sound channel 1 is bass
The 25% of the minimum lower frequency limit wavelength of loudspeaker 7, the area of the last end section of the bending section 11 of sound channel 1 first are raised for bass
Sound device 7 vibrates the 70% of area.In addition, forming the sound channel 1 and opening 3 of bugle shape, its main function is to be used to play bass
Part, therefore, the interface channel 6 between high pitch loudspeaker installing port 5 and sound channel 1 are extremely tiny, and its width is preferably 3 ~
5mm.A high point is somewhat mixed in bass, the tonequality played out more has characteristic.Preferably, add in sound channel 1
Added with appropriate acoustical cotton, allow pipeline effectively expansion low-frequency energy.
Certainly, the above is the representative instance of the present invention, and in addition, the present invention can also have other a variety of specific implementations
Mode, all technical schemes formed using equivalent substitution or equivalent transformation, is all fallen within the scope of protection of present invention.
