Description
Technical field
The utility model relates to a kind of technical field of automobile components, particularly relates to a kind of warning sound eliminator for automobile.
Background technique
Mobile muffler, the noise produced when being mainly used in the generator operation reducing Motor Vehicle, to be automobile exhaust pipe be made up of the pipeline that two length is different its principle, these two pipelines first separately cross again, due to these two pipelines length difference equal the half of the wavelength of the sound wave that automobile sends, two row sound waves are interfered when superposing cancel out each other and weaken the sound intensity, the sound that biography is come reduces, thus plays the effect of noise reduction.
Due to two pipelines length difference equal the half of the wavelength of the sound wave that automobile sends, two row sound waves are interfered when superposing and cancel out each other and weaken the sound intensity, sound is reduced, thus plays the effect of noise reduction.Technical matters, is whether measurement enterprise has advance, whether possesses the market competitiveness, whether constantly can lead over the important indicator foundation of Competitor.Along with the development in China's warning sound eliminator for automobile market, associated core production technology application and research and development will become the focus of enterprises pay attention in the industry.Dissipative muffler mainly to utilize sound-absorbing porous material to reduce noise.Arrange in the duct on inwall sound-absorbing material being fixed on air-flow path or according to certain way, just constitute dissipative muffler.When sound wave enters dissipative muffler, a part of acoustic energy rubs and changes into thermal energy consumption and dissipates in the hole of porous material, makes to be weakened by the sound wave of silencing apparatus.Dissipative muffler just looks like the pure resistor element circuit in electricity, and sound-absorbing material is similar to resistance.Therefore, people just call dissipative muffler this silencing apparatus.Dissipative muffler is good to medium-high frequency soundproof effect, poor to low frequency soundproof effect.Silencing apparatus reduces the exhaust sound of motor, and high-temp waste gas can be discharged safely and effectively.Silencing apparatus, as a part for exhaust duct, should ensure that its exhaust is unimpeded, resistance is little and sufficient intensity.Silencing apparatus will stand 500 DEG C ~ 700 DEG C high-temperature exhaust airs, ensures, in the distance travelled of automotive regulations, not damage, do not lose soundproof effect.
Current existing baffler erasure effect is general, there is no good alarming effect simultaneously yet, actual erasure effect cannot be obtained, many times erasure effect is not good also cannot obtain in time, still use and cause very large inconvenience, so the utility model can address this problem, meet the actual demand in market.
Model utility content
The technical problems to be solved in the utility model is a kind of warning sound eliminator for automobile, can solve the deficiencies in the prior art part, realize erasure effect good while, simultaneously can not good to inner erasure effect time play timely reminding effect.
For solving the problem, the utility model adopts following technological scheme:
A kind of warning sound eliminator for automobile, it is characterized in that: comprise the first baffler and the second baffler, between described first baffler and described second baffler, be provided with connecting tube, be provided with multiple filter sheet in described connecting tube, described filter sheet is for being obliquely installed; The inwall of described first baffler forms silencer wall, the multiple noise reduction dish of vertical arrangement, the bulge loop of convex is formed in the middle part of described second baffler, second baffler internal cavity is separated the silencing cavity in 3 different sizes by described bulge loop, described silencing cavity inwall is provided with glass fibre acoustical cotton, the silencing cavity inwall being positioned at outlet port is provided with sound wave detector, and the outer wall of described second baffler is provided with to connect with described sound wave detector control strip and LED lamp bead.
