Abstract
The utility model discloses an automatic gain processing system. The system comprises a speed detector, a microprocessor and a sound effect processor. The speed detector obtains a current travelling speed in real time, and transmits the obtained current travelling speed data to the microprocessor connected with the speed detector. The microprocessor receives the current travelling speed data, and adjusts the low gain of the sound effect processor connected with the microprocessor according to the current travelling speed data. By using the automatic gain processing system provided by the utility model, the low gain of a car audio system can be automatically adjusted in real time based on the travelling speed, so that in a travel process, the sound effect of the car audio system is not influenced by the travelling speed.
Description
Technical field
The utility model belongs to vehicle audio technical field, more particularly, relates to a kind of automatic gain treatment system.
Background technology
Along with generally popularizing of automobile, user also more and more payes attention to the result of broadcast of vehicle audio.
At present, most vehicle audio, in vehicle traveling process, due to the noise of tire and pavement friction generation, the noise of engine, sound of the wind and other noises, capital is weakened the bass of vehicle audio, and especially, when the speed of a motor vehicle is too fast, the meeting that bass is heard still less.Therefore,, when the bass of vehicle audio is affected, user's experience sensation can be poor.
At present, in vehicle traveling process, because bass is subject to weakening the problem that user experiences sensation that affects, general processing method is, separately installs a special bass treatment system additional, is commonly called as " subwoofer ".But because good " subwoofer " price comparison is expensive, the cheap original tonequality of easy destruction, and there is certain potential safety hazard.Therefore, how rationally effectively solving in vehicle traveling process, because the bass of vehicle audio is affected, cause user's the poor problem of experience sense, is problem demanding prompt solution.
Utility model content
In view of this, the utility model provides a kind of automatic gain treatment system, can according to the speed of a motor vehicle, regulate automatically the bass gain of vehicle audio, makes the audio of vehicle audio can not be subject to the impact of the speed of a motor vehicle.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of automatic gain treatment system, comprising: speed detector, microprocessor and sound effect processor; Wherein:
Described speed detector Real-time Obtaining current line vehicle speed, and the current line vehicle speed data of obtaining are sent to connected microprocessor;
Described microprocessor receives described current vehicle speed data, and according to described current vehicle speed data, regulates the bass gain of connected described sound effect processor.
Preferably, the UART serial ports of described microprocessor is connected with described speed detector.
Preferably, described automatic gain treatment system also comprises: the power amplifier being connected with described sound effect processor.
Preferably, described speed detector is velocity transducer.
From above-mentioned technical scheme, can find out, the disclosed a kind of automatic gain treatment system of the utility model, Negotiation speed detector carries out Real-time Obtaining to the speed of current driving, and the current line vehicle speed data of obtaining according to speed detector by microprocessor, bass gain to sound effect processor regulates, realized and according to the speed of a motor vehicle, regulated automatically in real time the bass gain of vehicle audio, and then realized when driving, the audio of vehicle audio can not be subject to the impact of the speed of a motor vehicle.
