Description
Technical field
The utility model relates to a kind of auxetophone, particularly relates to a kind of auxetophone for battery-driven car.
Background technology
Due to the green low cost vehicle that battery-driven car is a kind of environmental protection, simultaneously because urban congestion, increasing people's trip all can select battery-driven car.
Existing battery-driven car has put into effect many battery-driven car standards, as maximum weight, speed, overspeed prompting etc., but the demand in market can not be met, therefore various battery-driven car that is overweight, hypervelocity can be found everywhere, a kind of novel electric vehicle auxetophone is provided in order to overcome this difficult problem, by detecting throttle (handle) signal voltage modulating output motor bike sound, driving and having the vehicle of this device to remind pedestrian and cart in time.
Utility model content
The utility model is intended to address the aforementioned drawbacks, and provides a kind of auxetophone for battery-driven car.
In order to overcome the defect existed in background technology, the utility model solves the technical scheme that its technical matters adopts: this auxetophone for battery-driven car comprises 32 bit DSP audio decoder process chip, the input of described 32 bit DSP audio decoder process chip connects digital audio storage and function switches A/D sampling setup, the output of 32 bit DSP audio decoder process chip connects digital audio storage and stereo sound audio amplifier, the output of described stereo sound audio amplifier connects left horn and right horn, the input that described function switches A/D sampling setup connects speed-regulating handle bar.
The beneficial effects of the utility model are: this auxetophone for battery-driven car only need provide 9-15V power supply and a convert signals and starting switch, dynamic loud-speaker switch, main frame accelerates roar along with handle signal intensity exports motor bike in motion, the enjoyment of riding in enjoyment also can remind other people's vehicle close, avoid shining into injury to other people, also remind cart to guarantee oneself traffic safety simultaneously, and respond national standard battery-driven car speed reach 25 kilometers per hour time adjoint must can not be less than the auditory tone cues of 60 decibels.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, for functional block diagram of the present utility model, comprise 32 bit DSP audio decoder process chip, the input of described 32 bit DSP audio decoder process chip connects digital audio storage and function switches A/D sampling setup, the output of 32 bit DSP audio decoder process chip connects digital audio storage and stereo sound audio amplifier, the output of described stereo sound audio amplifier connects left horn and right horn, and the input that described function switches A/D sampling setup connects speed-regulating handle bar.Its principle is, when startup battery-driven car provides 9-15V power supply to auxetophone main frame, press and be arranged on electronic driver upper switch activated auxetophone, start to switch A/D to speed-regulating handle bar voltage signal by function after startup to sample, signal after sampling sends into the professional high-fidelity of 32 bit DSP audio decoder chip, at a high speed, wide dynamic process follows the tracks of process along with A/D sampling height unlike signal, sends into stereo sound audio amplifier and carries out amplification and export to sound horn will read signal from DAB holder.
The utility model is installed and simple only need be provided 9-15V power supply and a convert signals and starting switch, dynamic loud-speaker switch, main frame accelerates roar along with handle signal intensity exports motor bike in motion, the enjoyment of riding in enjoyment also can remind other people's vehicle close, avoid shining into injury to other people, also remind cart to guarantee oneself traffic safety simultaneously, and respond national standard battery-driven car speed reach 25 kilometers per hour time adjoint must can not be less than the auditory tone cues of 60 decibels.In every case be by MP3, Car Burglar Alarm or any one sound-producing device, export motor bike roar (sound comprises, motor, automobile, music, animal sounds etc.) all at this patent protection domain as long as reached by detection handle signal or motor signal.
