Description
Technical field
The utility model relates to car horn optimal design field, particularly relates to a kind of car horn that can reduce pilothouse noise.
Background technology
Car horn is divided into air horn and electric horn two kinds by audio power, and electric automobile horn leans on the vibration of metallic membrane thus sounds.By the periodic duty of solenoid electric valve, repeatedly drive the motion of vibrating membrane, then make vibrating membrane sound, and soundboard and diaphragm rigid attachment, can make vibration smooth-going sound more melodious.The principle of work of air horn utilizes compressed-air actuated air-flow to make metallic membrane vibrate and sound, and air horn generally adopts tubular, and uses high pitch and bass two loudspeaker associated working.But the loudspeaker of two types have a common problem, that can cause driving room noise because of tucket exactly, because do not have the equipment of noise reduction or sound insulation around loudspeaker, causes the cause that tucket is propagated to surrounding.The insulation works of system generally completes through damping, noise reduction, sealing three steps, generally must use high-tech quieter material that vehicle body is carried out car insulation works, or use coating to carry out sound insulation etc. in car domain, and the price of these measures is often higher.
Utility model content
The purpose of this utility model is just to provide a kind of car horn that can reduce pilothouse noise to solve the problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of car horn that can reduce pilothouse noise, comprise shock-absorbing firm banking, solenoid electric valve, quiet long cylinder gabarit, noise reduction exhaust cap, the long cylinder that amplifies is provided with above described shock-absorbing firm banking, the described long cylinder outer setting that amplifies has described quiet long cylinder gabarit, described shock-absorbing firm banking edge is provided with described solenoid electric valve, binding post is stretched out at described solenoid electric valve top, gabarit erection support is provided with around the described long cylinder that amplifies, described shock-absorbing firm banking bottom is provided with described noise reduction exhaust cap, described noise reduction exhaust cap inside is provided with rear portion end cap, described rear portion cover internal is provided with vibrating membrane, described shock-absorbing firm banking center is provided with column O-ring seal.
In said structure, loudspeaker are fixedly mounted on car body by described shock-absorbing firm banking, described solenoid electric valve controls the sounding of vibrating membrane described in loudspeaker, send after sound expands by the described long cylinder that amplifies further, sound is pooled to car body front and sends by described quiet long cylinder gabarit, and stop sound to be propagated mutually around, described noise reduction exhaust cap will ensure that the direction of propagation of sound is forward, so just reduces the loudspeaker noise in pilothouse.
In order to reduce the loudspeaker noise in pilothouse further, described in the long cylinder that amplifies be screwed on the surface of described shock-absorbing firm banking, be fixed on described shock-absorbing firm banking outside the long cylinder that amplifies described in described quiet long cylinder gabarit is enclosed within.
In order to reduce the loudspeaker noise in pilothouse further, described solenoid electric valve is connected with described binding post by wire on described shock-absorbing firm banking by screw fastening.
In order to reduce the loudspeaker noise in pilothouse further, described gabarit erection support and the integrated design of described shock-absorbing firm banking, described noise reduction exhaust cap is connected with described shock-absorbing firm banking lower seal.
In order to reduce the loudspeaker noise in pilothouse further, described shock-absorbing firm banking surface screw is provided with described rear portion end cap, described rear portion end cap stitching also fixes described vibrating membrane, and described shock-absorbing firm banking and the described long cylinder that amplifies compress described column O-ring seal.
Beneficial effect is: reduce speaker sound to the propagation in pilothouse by lower cost, and the use of damping facility reduces the vibration of loudspeaker, extends the serviceable life of loudspeaker.
