Abstract
The invention discloses a denoising device which comprises a denoising device shell. An outer folding plate is vertically installed in the denoising device shell. The top of the outer folding plate is fixed to the inner top face of the denoising device shell. The bottom of the outer folding plate is suspended. A sound guide pipe is installed on one side of the outer folding plate. One end of the sound guide pipe is fixedly connected with the outer folding plate. The other end of the sound guide pipe is fixed to a noise elimination device. The sound guide pipe is communicated with the noise elimination device. A microphone is arranged in the noise elimination device and corresponds to the sound guide pipe. A microphone base is installed on one side of the microphone. The microphone base and the microphone are detachably connected with each other. A filter pipe is arranged on one side of the microphone base and penetrates through the microphone base and the microphone to be connected with the sound guide pipe. One end of the filter pipe is provided with an end socket. By means of the denoising device, reflection standing waves, in the sound guide pipe, of sound waves are reduced, the transmission coefficient, in the sound guide pipe, of the sound waves is increased, and therefore the denoising effect is achieved; meanwhile, the noise sound waves can stay longer in the noise elimination device, and the secondary denoising effect is achieved.
Description
Technical field
The present invention relates to a kind of computer installation, particularly a kind of denoising device.
Background technology
In modern multimedia communication process, audio frequency input has become a very important ring, and in the communication apparatus such as mobile phone, computer, intercom and various special traffic headsets, speech input device is widely used.And along with the continuous progress of technology, the requirement of user to phonetic entry quality is also more and more higher.In phonetic entry process, the impact and the interference that how to reduce environmental noise are dark concerned problems always.If good noise reduction cannot be accomplished, just likely affect the use of user, in use can not obtain satisfied effect.Although general denoising device can play certain Noise Reduction, noise reduction is also not obvious, also needs to make corresponding improvement for series of problems, makes its user's result of use better.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the problems referred to above, provides the reflection standing wave of a kind of sound wave in acoustic conducting pipe, improves the transmission coefficient of sound wave in acoustic conducting pipe, thus serve the denoising device of Noise Reduction.
To achieve these goals, the technical solution used in the present invention is such: denoising device of the present invention, comprise denoising device housing, vertically outer flap is installed in denoising device housing, outer flap top is fixed on denoising device housing inner top surface, unsettled bottom it, its side is provided with acoustic conducting pipe, acoustic conducting pipe one end is fixedly connected with outer flap, its other end is fixed on a noise eliminator, and acoustic conducting pipe is communicated with noise eliminator, microphone is provided with in noise eliminator, the corresponding acoustic conducting pipe of microphone is arranged, microphone side is provided with Microphone stand, removably is adopted to be connected between Microphone stand with microphone, Microphone stand side is provided with screen pipe, screen pipe is each passed through Microphone stand and microphone is connected with acoustic conducting pipe, screen pipe one end is provided with termination, screen pipe is fixed on termination, the side that termination is positioned at screen pipe has bloop.
Further, as a kind of concrete version, there is in acoustic conducting pipe of the present invention three rank or quadravalence filtering sound chamber.
Further, as a kind of concrete version, denoising device housing of the present invention is provided with sound inlet, and sound inlet communicates with acoustic conducting pipe.
Further, as a kind of concrete version, acoustic conducting pipe of the present invention and noise eliminator are fixed by fixing boots.
Further, as a kind of concrete version, between microphone of the present invention and Microphone stand, buffer layer is installed.
Compared with prior art, the invention has the advantages that: this denoising device reduces the reflection standing wave of sound wave in acoustic conducting pipe, improve the transmission coefficient of sound wave in acoustic conducting pipe, thus serve Noise Reduction, the time of staying of noise sound wave in noise eliminator can be extended simultaneously, serve the effect of secondary noise reduction.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention;
In figure: 1. denoising device housing; 2. outer flap; 3. acoustic conducting pipe; 4. noise eliminator; 5. screen pipe; 6. microphone; 7. Microphone stand; 8. termination; 9. bloop.
