Car volume control system

Abstract

The invention relates to a vehicular volume control system which comprises an external noise detection module, an internal noise detection module and a volume controller module. The external noise detection module and the internal noise detection module respectively detect noise of an external environment of a vehicle and noise of an internal environment of the vehicle, and the volume controller module is connected with the external noise detection module and the internal noise detection module to determine the volume of an external loudspeaker of the vehicle and the volume of an audio loudspeaker of the vehicle according to detection results of the external noise detection module and the internal noise detection module. The vehicular volume control system has the advantages that the volume of the external loudspeaker of the vehicle and the volume of the audio loudspeaker of the vehicle can be adaptively modified in real time according to detection results of the noise of the internal environment of the vehicle and the noise of the external environment of the vehicle, and problems that pedestrians cannot hear reminding sound of the loudspeaker due to the noise and a driver of the vehicle cannot hear sound of incoming calls of a mobile phone due to the noise are solved.

Description

technical field [0001] The invention relates to the audio field, in particular to a vehicle volume control system. Background technique [0002] The car is an important means of transportation used by people, and it is also a space where people stay for a relatively long time. In order to avoid people traveling long distances or waiting for a long time to be too boring, many entertainment facilities are installed in the car, such as audio equipment, radios and car TVs. At the same time, horns and lighting facilities on the car body are also tools that people often use to see the road and remind pedestrians to avoid, so as to avoid safety accidents. [0003] However, due to the existence of many noise sources during the passage of automobiles, such as construction sites, passing vehicles, entertainment venues, pedestrians, etc., the volume of the car's external horns and in-car audio horns is generally fixed or needs to be adjusted manually. When the environmental noise poll...

[0003] However, due to the existence of many noise sources during the passage of automobiles, such as construction sites, passing vehicles, entertainment venues, pedestrians, etc., the volume of the car's external horns and in-car audio horns is generally fixed or needs to be adjusted manually. When the environmental noise pollution outside the car is serious, pedestrians cannot hear the whistle warning sound of the horn outside the car, causing serious safety hazards, and it is easy to appear when the environmental noise pollution inside the car is serious, and the car users in the car cannot hear the car stereo or Bluetooth The sound of the mobile phone prevents you from enjoying the entertainment and services you deserve
