一种车载音响
摘要：
本发明公开了一种车载音响，涉及车载音响，尤其涉及一种带有音频变频模块可将音响音频与汽车速率同比例变化的车载音响；包括车载音响及车速传感器，车载音响包括音响主控电路及扬声器，本发明还包括车速采集模块及音频变频模块，车速采集模块及音频变频模块设置于音响主控电路；其有益效果在于：在车载音响的音响主控电路上加设车速采集模块及音频变频模块，通过车速采集模块采集到汽车的速率，并将汽车速率传递给音频变频模块，音频变频模块综合分析汽车速率和音响主控电路中的音频信号并进行数据处理，然后，音频变频模块将输出一种与汽车速率成同比例增加或减小音频并输送到扬声器上。
摘要（英）：

The invention discloses a vehicle audio system, in particular to a vehicle audio system which is provided with an audio conversion module capable of changing the audio frequency of the audio system and the vehicle velocity in the same proportion. The vehicle audio system comprises a vehicle audio device and a vehicle velocity sensor, wherein the vehicle audio device comprise an audio main control circuit and a speaker. The invention also comprises a vehicle velocity acquisition module and an audio conversion module which are arranged in the audio main control circuit. The invention has the advantages that the vehicle velocity acquisition module and the audio conversion module are additionally arranged on the audio main control circuit of the vehicle audio system, and the vehicle velocity is acquired through the vehicle velocity acquisition module and transferred to the audio conversion module which comprehensively analyzes the vehicle velocity and an audio signal in the audio main control circuit, processes data and then outputs and transmits an audio frequency to the speaker, wherein the audio frequency is increased or decreased in the same proportion to the vehicle velocity.
