Description
Technical field
The utility model belongs to automobile sound control field, the sound transmission device that particularly a kind of automobile car is interior and car is outer.
Background technology
For senior car, quiet more in order to make in the car, the seal degree of its railway carriage (doubling glass window) is very high.Be unfavorable for that exterior sound imports in the car.Unfavorable car is interior and the people's that car is outer sound two-way exchange.Toot the flute speaker sound of vehicle before and after being unfavorable for hearing.Be unfavorable for traffic safety.
(example passenger outside the car of bus inquires the route of chaufeur when the people outside Che Nei and the car needs the sound two-way exchange; The traffic police inquires chaufeur; Car when the malice pushing-off the wagons is plundered is interior and the people's that car is outer sound exchanges.) need open car door or wind glass so that the transmission of sound.But the speed of opening car door or wind glass is slower, and load has been engaged in the time, when using air-conditioning in car, is unfavorable for that the air themperature in the car is stable, also is unfavorable for the air quality in the car.
When running into the robbery of malice pushing-off the wagons, open the safety that car door or wind glass are unfavorable for the occupant.
Summary of the invention
The purpose of this utility model: provide in a kind of automobile car and the outer sound transmission device of car, when needing the sound two-way exchange outside Che Nei and the car, need not open car door or wind glass, help traffic safety, help occupant's safety.
The utility model mainly comprises: microphone, loudspeaker, circuit etc.
It is realized by the following method, 8 microphone 2, loudspeaker 4 is housed on one side in the car of car body 5; Outside the car of car body 5,9 microphone 1, loudspeaker 3 are housed on one side; Microphone, loudspeaker junction circuit.
The beneficial effects of the utility model are: simple in structure, when needing the sound two-way exchange outside Che Nei and the car, need not open car door or wind glass, and help traffic safety, help the safety of occupant, driving.
Description of drawings
The utility model is described in further detail below in conjunction with figure.
Fig. 1 is the structural representation of the utility model installation site.
Fig. 2 is the structural representation of the utility model installation site.
Fig. 3 is a circuit diagram of the present utility model.
As Fig. 1: in the car of car body 5,8 microphone 2, loudspeaker 4 are housed on one side; Outside the car of car body 5,9 microphone 1, loudspeaker 3 are housed on one side.Car body 5, wheel 7.
Microphone also claims microphone or claims microphone that its effect is that aud. snl. is converted into electric signal.
Loudspeaker also claims loud speaker or claims earphone that its effect is that electric signal is converted into aud. snl..
8 microphone 2, loudspeaker 4 are housed on one side in the car of car body 5, its effect is respectively: aud. snl. in the car is converted into electric signal; Be that electric signal is converted into aud. snl. in the car.
9 microphone 1, loudspeaker 3 are housed on one side outside the car of car body 5, its effect is respectively: the outer aud. snl. of car is converted into electric signal; Be that electric signal is converted into the outer aud. snl. of car.
As Fig. 2: automobile exterior mirror 10, bearing circle 11,
At automobile exterior mirror 10 places microphone 1 or loudspeaker 3 are housed.Microphone 1, loudspeaker 3 can be contained in the light deflector shell of automobile exterior mirror 10, and loudspeaker 3 also can be contained in the support of automobile exterior mirror 10.Its effect is respectively: the outer aud. snl. of car is converted into electric signal; Be that electric signal is converted into the outer aud. snl. of car.
On one side 8 microphone 2, loudspeaker 4 are housed in the car of car body 5, microphone 2 can be contained in 11 li of bearing circle, also can be contained in car panel or the seat headrest, and loudspeaker 4 can be contained in the car panel or be shared with the sound equipment loudspeaker in the existing automobile.Its effect is respectively: aud. snl. in the car is converted into electric signal; Be that electric signal is converted into aud. snl. in the car.
As Fig. 3: circuit 15, circuit 15 can have a talkback circuit function technology for existing, also can increase recording circuit and recording memory device in talkback circuit 15.
Feeder ear power connection one utmost point of circuit 15, another utmost point of another feeder ear of talkback circuit 15 power connection after series connected switches 16.
Switch 16 can be arranged in one with other sound master cock of automobile.Can select switch 16 always opposite with the on off state of other sound master cock of automobile.Promptly when switch 16 is connected, other sound master cock automatic cutout.Promptly when switch 16 disconnected, other sound master cock was connected automatically.
Switch 16 can adopt manual time-delay cut-off switch, and for example little Mao postpones a few minutes automatic cutout after manually connecting.
The specific embodiment
When the people outside Che Nei and the car needs the sound two-way exchange, manually connect switch 16 after, circuit 15 energising work.
Microphone 1 is converted into electric signal to the outer aud. snl. of car and passes to circuit 15, and circuit 15 makes signal the people hear sound outside the car in car by loudspeaker 4 after treatment.
Microphone 2 is converted into electric signal to aud. snl. in the car and passes to circuit 15, and circuit 15 makes signal people outside car hear sound in the car by loudspeaker 3 after treatment.
Need not open car door or wind glass this moment, only needs by microphone 1,2; Loudspeaker 3,4; Circuit 15 promptly can reach the purpose of sound two-way exchange.
Can be not slower because of the speed of opening car door or wind glass, load has been engaged in the time.
When using air-conditioning in car, the air themperature that helps in the car is stable, also helps the air quality in the car.
When running into the robbery of malice pushing-off the wagons, help occupant's safety.
