Description
The utility model relates to a kind of multi-purpose vehicle(MPV) loudspeaker, belongs to automobile aural signal configuring technical field.
The electromagnetism car horn has used last 100 years, though technology has improvement, effect does not improve what.Electronic sound-producing device begins to use on automobile in recent years, for example, the reversing sound generating mechanism, about turning sound generating mechanism and the electronics generator etc. of blowing a whistle, make traditional automobile sound configuration that great variety take place, but existing this electron-like sound-producing device function singleness cause configuration mixed and disorderly, use and maintenance has inconvenience, this defective brings difficulty also for the popularization of electronic horn.
The purpose of this utility model is to disclose a kind of multifunction electronic car horn, realizes blowing a whistle sounding with integrated electronic circuit, automatic speech sounding and multiple function such as amplify.
The purpose of this utility model is achieved in that
A kind of multifunction electronic car horn, it contains a multifunction speech circuit at least and with the sound of blowing a whistle circuit 3 and a public power amplifier 4 takes place more than 2, one.Be provided with a multifunction chip IC1 in the multifunction speech circuit, an on-off circuit K2 is located between the voice selecting end and ground wire of chip IC 1, and resistance R 2 connects between chip IC1 output terminal and the public power amplifier input end.How with the sound of blowing a whistle circuit to take place and be provided with a multiple sound chip IC2 that blows a whistle, an on-off circuit K4 is located between these chip IC 2 selecting sides and the car horn button K3, and resistance R 3 is connected between chip IC 2 output terminals and the public power amplifier input end.
For satisfying the design specifications of car horn, public power amplifier 4 is push-pull circuits of being made up of two high-power power amplifier chip IC 3 and IC4.
This device also can add a microphone pre-amplification circuit 1 again, is made up of two stage amplifer circuit G1 and G2, and output terminal is connected with public power amplifier input end through capacitor C 2, resistance R 1.
After adopting technique scheme, the electronic car loudspeaker become the extremely wide product of a kind of scope of application, its the multiple sound of blowing a whistle can be selected to set by the different of vehicle or according to driver's different needs and hobby, can send the voice sound of multiple expression driving states during driving automatically, the driver also can directly use microphone during special requirement, and all above-mentioned functions all can utilize an integrated circuit arrangement to realize, use reliable, need repairing hardly, thereby the utmost point is convenient to the using and promoting in automobile industry of electronic car loudspeaker.
Below in conjunction with drawings and Examples the utility model is specified.
Fig. 1 is the utility model circuit block diagram;
Fig. 2 is the utility model electrical schematic diagram.
In Fig. 1, the utility model comprises microphone pre-amplification circuit 1, and how multifunction speech circuit 2 with the sound of blowing a whistle circuit 3 and a public power amplifier 4 takes place, and the three constitutes a compact electronic apparatus.In microphone pre-amplification circuit 1, be provided with microphone and combined socket and switch 5, in multifunction speech circuit 2, be provided with voice selecting switch or connection terminal 6, with the sound of blowing a whistle the sound of blowing a whistle take place to be provided with in the circuit 3 how and select to set splicing ear and horn button connection terminal 7.Be provided with electric horn connection terminal 8 in the public power amplifier 4.The shared vehicle-mounted 12V direct supply of entire circuit.
The pre-amplification circuit of microphone described in Fig. 2 is made of in homophase amplification mode two-stage calculation amplifier G1 and G2, the normal phase input end of prime G1 is connected with microphone MIC through capacitor C 1, and the output terminal of back level G2 adds to public power amplifier input end through capacitor C 2 and resistance R 1.A button switch K 1 is arranged in the current supply circuit of operational amplifier, be located on the microphone, press K switch 1 in the time of need amplifying, make transport and placing device G1, G2 work.G1 and G2 are an integrated chip LF353 in the side circuit.
