Abstract
The utility model discloses a multi-channel audio vehicle electronic horn, including a horn, a button switch, a shell, a sound control circuit disposed in the shell. The sound control circuit referred includes a three-terminal steady voltage block connected to the power of the vehicle. A microcontroller and a digital to analog converter are connected to the other end of the three-terminal steady voltage block. A crystal shaker is connected to the other end of the microcontroller. The crystal shaker is connected to the digital to analog converter and the light emitting display. Another circuit of the microcontroller is connected to a signal channel, a signal amplifier, a voltage comparator, and a power amplifier. One end of the button switch is connected to the microcontroller. The utility model sent corresponding sound according to different environment, and display corresponding different color of light through controlling the light emitting display. Thus, comparing to the prior art, the plurality of sounds of the born can coincide with the surrounding environment and reduce the noise pollution to the environment.
Description
One, technical field
The utility model relates to a kind of electronic vehicle horn.
Two, background technology
Existing automobile electronic loudspeaker all is single-tone, double-tone horn, and its pronunciation is dull, uninteresting, the needs of incompatibility modern city and rural various road conditions.And also environment has been caused noise emission to a certain extent.
Three, utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of multichannel automobile electronic loudspeaker that can send alternative sounds according to varying environment is provided.
The purpose of this utility model realizes by following technical solution: a kind of multichannel automobile electronic loudspeaker comprises loudspeaker, push switch, housing, is contained in the sound control circuit in the housing; Described sound control circuit comprises signal line, signal amplifier, voltage comparator, power amplifier, one end of power amplifier links to each other with loudspeaker, this sound control circuit also comprises the three-terminal regulator block that links to each other with automobile power source, the other end of described three-terminal regulator block connects microcontroller and D and A converter respectively, the other end of described microcontroller is connected with crystal oscillator, described crystal oscillator and D and A converter, active display connects, described microcontroller divides one the tunnel and signal line again, signal amplifier, voltage comparator, power amplifier connects, and an end of push switch links to each other with microcontroller again; Described microcontroller adopts integrated circuit CF745 chip module, and described crystal oscillator is made up of quartz crystal, and described active display is made up of light-emitting diode.
After adopting the utility model structure, because microcontroller prepares a computer program by the CF745 chip module and designs the control and the switching of multiple sound, make automobile electronic loudspeaker send the sound that adapts with it, send the light of corresponding different color simultaneously by the control active display in varying environment.Therefore, the utility model compared with prior art, the multiple sound of these loudspeaker and surrounding environment have been accomplished harmonious, thereby have alleviated the noise emission to environment.
Four, description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.
Fig. 1 is the circuit block diagram of the utility model multichannel automobile electronic loudspeaker.
Fig. 2 is the schematic circuit diagram of the utility model multichannel automobile electronic loudspeaker.
Five, the specific embodiment
With reference to Fig. 1, Fig. 2 as can be known, the utility model multichannel automobile electronic loudspeaker is made up of loudspeaker 1, push switch 2, housing, the sound control circuit that is contained in the housing; Described sound control circuit comprises signal line 8, signal amplifier 9, voltage comparator 10, power amplifier 11, one end of power amplifier 11 links to each other with loudspeaker 1, this sound control circuit also comprises the three-terminal regulator block 3 that links to each other with automobile power source, the other end of described three-terminal regulator block 3 connects microcontroller 4 and D and A converter 5 respectively, the other end of described microcontroller 4 is connected with crystal oscillator 6, described crystal oscillator 6 and D and A converter 5, active display 7 connects, described microcontroller divide again one the tunnel with signal line 8, signal amplifier 9, voltage comparator 10, power amplifier 11 connects, and an end of push switch 2 links to each other with microcontroller again; Described microcontroller adopts integrated circuit CF745 chip module, and described crystal oscillator is made up of quartz crystal, and described active display is made up of light-emitting diode.The integrated circuit model of three-terminal regulator block is 7805 in the present embodiment; Signal line is made up of aerotron Q9, Q10 etc.; Signal amplifier is made up of aerotron Q1, Q2 etc.; Voltage comparator is made up of aerotron Q3, Q4 etc.; Power amplifier is made up of aerotron Q5, Q6, Q7, Q8 etc.; Microcontroller is selected C for use by the CF745 chip module
++Programme eight kinds of sound of design and of JaVa machine language by the intensity serial arrangement, interlaced from the forte to the minor; D and A converter 5 is eight bit string parallel digital to analog converters, and its integrated circuit model is 74LS164; Active display 7 is made up of eight light-emitting diodes.
The utility model energized is started working, and makes power line voltage through three-terminal regulator block output+5V voltage for microcontroller and eight bit string parallel digital to analog converters by 12V or 24V vdc.Selector button switch triggering microcontroller is by crystal oscillator, eight bit string parallel digital to analog converters then, and the light-emitting diode that drives active display sends the light of eight kinds of different colors.The synchronous signal passage receives the signal and the conducting of being sent by microcontroller and amplifies through signal amplifier, compare through voltage comparator again, send eight kinds of different sound that adapt with surrounding environment for power amplifier promotion loudspeaker thereby export normal working voltage at last.As using finger-popping long, remind the other side to note at the mountain area bend; Available loud and clear long is paid attention to the pedestrian on the meagrely-populated road in rural area; Available melodious, soft long (or minor) on town road reduces city noise pollution; Crossing highway the pedestrian can not make the pedestrian frightened with soft minor; Can make front driver not hear the signal or the like of overtaking other vehicles with rapid long at turnpike driving.So, the utility model compared with prior art, the multiple sound of these loudspeaker and surrounding environment have been accomplished harmonious, thereby have alleviated the noise emission to environment.
