Figure；
Fig. 2 is the schematic structure of a kind of device imitating automobile exhausting sound described in the embodiment of the present invention
Block diagram.
Detailed description of the invention
Being described principle and the feature of the present invention below in conjunction with accompanying drawing, example is served only for explaining this
Invention, is not intended to limit the scope of the present invention.
The signal of a kind of method 100 imitating automobile exhausting sound that Fig. 1 provides for the embodiment of the present invention
Property flow chart.Method 100 as shown in Figure 1 includes:
110, rotate handle or the speed governing pedal of electric motor car, make the voltage letter of handle or the output of speed governing pedal
Number change.
120, voltage signal transmit to signal generator, this signal generator according to voltage signal produce with
The signal of telecommunication of automobile exhausting sound same frequency, the frequency of the signal of telecommunication with voltage signal change increase or
Reduce.
130, signal of telecommunication transmission to signal amplifier, the signal of telecommunication being amplified is processed through signal amplifier.
140, the signal of telecommunication amplified is transmitted to speaker, the signal of telecommunication of amplification is converted into phase by speaker
Answer the sound of loudness.
A kind of method imitating automobile exhausting sound that above-described embodiment provides, at electric motor car driving process
In can change output according to actual running environment by the handle or speed governing pedal rotating electric motor car
Voltage signal, this voltage signal drive signal generator produces the electricity with automobile exhausting sound same frequency
Signal, the signal of telecommunication is converted to the sound of corresponding loudness after signal amplifier by speaker, when passerby hears
Can hide in time, thus reduce the probability of electric motor car generation vehicle accident.
Concrete, in this embodiment it is possible to gradually rotate handle or the tune of electric motor car in one direction
Speed pedal, makes the voltage signal of handle or the output of speed governing pedal that change from small to large to occur, or from greatly
To little change.
Or, it is also possible to the handle of reciprocating rotation electric motor car in two opposite directions or speed governing pedal,
There is change from small to large, or change from big to small in the voltage signal making handle or the output of speed governing pedal
Change.
