As an improvement of the above scheme, baffle is equipped in shell, baffle extends inside the shell is divided into the space in shell
There are gap between the bottom surface of upper layer and lower layer, baffle and shell, which forms air outlet.
As an improvement of the above scheme, it is 30~70cm that air outlet, which gos deep into the depth of interior of shell,.
As an improvement of the above scheme, several gussets extended along air outlet depth direction are equipped in air outlet.
As an improvement of the above scheme, the left and right side on the inside of shell, upper and lower end face and the back side are in common intersection shape
At four reflectings surface, four reflectings surface are inclined-plane.
As an improvement of the above scheme, it sees with overlooking, the trapezoidal shape in the inside of shell, the wider side of shell is front,
The relatively narrow side of shell is the back side.
As an improvement of the above scheme, shell stainless steel sheet body made of casting, shell with a thickness of 2~4cm, this
When shell outside be also inclined-plane close to the positions of four reflectings surface.
As an improvement of the above scheme, control assembly includes clamshell, control panel, Wiring port, radiator and fan, wiring
Port is located at the back side of shell and exposed, and control panel, radiator and fan are installed in the inside of clamshell.
The utility model has the beneficial effects that this loudspeaker ingehious design position of air outlet, the air of inside loudspeakers
When vibration, ground can be flowed out and impacted from air outlet, after designing air outlet height, sound wave can be with bass after ground return
The sound superposition that loudspeaker front issues, final effect is that the lower limit of bass can be lower.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawing:
Fig. 1 is the perspective view of loudspeaker；
Fig. 2 is the cross-sectional view of loudspeaker；
Fig. 3 is the top view of loudspeaker；
Fig. 4 is frequency response curve.
Specific embodiment
Referring to figs. 1 to Fig. 4, the utility model is a kind of loudspeaker for optimizing sense of hearing, including shell, high-pitched speaker 2, bass
Loudspeaker 1, control assembly 5 and air outlet 3, control assembly 5 are located at the inside of shell, high-pitched speaker 2, woofer 1 and air outlet 3
It is distributed in the front of shell from top to bottom.Using the bottom of shell as zero datum, air outlet 3 is located at height in the area of 4~16cm
Between.This loudspeaker ingehious design position of air outlet 3 when the air vibration of inside loudspeakers, can flow out and rush from air outlet 3
Hit ground；After designing 3 height of air outlet, sound wave can be superimposed after ground return with the sound that 1 front of woofer issues,
Final effect is that the lower limit of bass can be lower.It of courses, loudspeaker can also be placed on other platforms, but ensure
The sound wave that air port 3 is flowed out can reflect superposition.
3 moulding of air outlet of dotted air outlet 3 and strip is different, sound wave using above-mentioned two position as source of sound,
Have different waveforms.In the present embodiment, baffle is equipped in shell, baffle extends inside the shell is divided into the space in shell
Two layers lower, there are gap between baffle and the bottom surface of shell, which forms air outlet 3.Although space in shell is divided into
It is two layers lower, but baffle does not reach the back side of shell, bilevel space still maintains connection at this time, and connection is located proximate to
The back side of shell.Since air outlet 3 is not pipe-like, so the width of entire air outlet 3 is substantially equal to the front of shell
Width is spread around convenient for sound wave.In order to advanced optimize the transmitting of sound wave, direct sound waves flowing, air outlet 3 gos deep into shell
Internal depth is 30~70cm.
Several gussets 4 extended along 3 depth direction of air outlet are equipped with as preferred embodiment, in air outlet 3.This
In embodiment be provided with two gussets 4, while two gussets 4 in outside diffusion type distribution, i.e., gusset 4 close to interior of shell one
Side is in collect shape.
Referring to Fig. 4, wherein a curve generated for conventional speakers, is set as the first curve 11；Another is this Shen
Please scheme generate curve, be set as the second curve 12.Under identical conditions test, as seen from Figure 4, in 20Hz to 150Hz
The acoustic pressure for optimizing the loudspeaker of low-frequency effect is 5dB higher than the acoustic pressure of conventional speakers, and conventional speakers are compensated for from sense of hearing
Low frequency dint degree is insufficient, the not full effect of sound.I.e. sound caused by application scheme allows people more comfortably to put down and plows.
Standing wave refers to that the opposite wave in two directions of propagation uploads sowing time, the wave that the two is overlapped mutually in same horizontal line.Loudspeaker
Sounding, most of sound wave spread out of from front, and small part spreads out of from front again after toward transmitting inside speaker.The technical program
There are also the effect of anti-standing wave, two improvements are combined, and can advanced optimize sense of hearing.
With the orientation references benchmark in Fig. 2 for illustrating, left and right directions indicates front and back hereafter in Fig. 2, up and down
Direction indicates upper surface and lower end surface hereafter, and paper front-rear direction indicates right side and left side hereafter.On the inside of shell
Left and right side, upper and lower end face and the back side form four reflectings surface 6 in common intersection, and four reflectings surface 6 are inclined-plane, and four anti-
Penetrating face 6 is triangle.Left and right side, upper and lower end face and the back side described herein be all on the basis of the inner space of shell,
The external styling of shell does not do stringent limitation.Multidirectional scattering occurs for the sound wave in shell, can upset significantly the frequency of sound wave
Rate so avoids the generation of standing wave so that internal sound wave and audience wants received sound wave and generate biggish difference.
As preferred embodiment, to see with overlooking, the trapezoidal shape in the inside of shell, the wider side of shell is front,
That is below Fig. 3；The relatively narrow side of shell is the back side, i.e. the upper surface of Fig. 3.When the sound wave that loudspeaker issue is transmitted to the inside of shell
When, left and right side is mutually inclined, also being capable of scattered sound waves.Reflecting surface 6 is in scattered sound waves there are six can be regarded as in this way.
As preferred embodiment, shell stainless steel sheet body made of casting, shell with a thickness of 2~4cm.This
When shell outside in the position close to four reflectings surface 6 be also inclined-plane, the moulding of shell be similar to substantially it is mentioned above just
The back side, upper and lower end face and left and right side.
As preferred embodiment, control assembly 5 includes clamshell, control panel, Wiring port, radiator and fan, is connect
Line end mouth is located at the back side of shell and exposed, and control panel, radiator and fan are installed in the inside of clamshell.
Certainly, the design creation is not limited to above embodiment, and the combination of the various embodiments described above different characteristic can also
To reach good effect.Those skilled in the art can also make without departing from the spirit of the present invention
It is all included in the scope defined by the claims of the present application with deformation or replacement, these equivalent variation or replacement.
