Vehicle-mounted volume control system

Abstract

The invention relates to a vehicle-mounted volume control system. The vehicle-mounted volume control system comprises an exterior noise detection module, an interior noise detection module and a volume controller module, wherein the exterior noise detection module and the interior noise detection module are used for detecting a noise of an environment outside an automobile and a noise of an environment inside the automobile respectively; and the volume controller module is connected with the exterior noise detection module and the interior noise detection module in order to determine volumes of an automobile exterior horn and an automobile sound horn respectively according to detection results of the exterior noise detection module and the interior noise detection module. Through adoption of the vehicle-mounted volume control system, the volumes of the automobile exterior horn and the automobile sound horn can be changed adaptively in real according to detection of the interior and exterior environmental noises; a situation that pedestrians cannot hear prompts of the horns due to the noises is avoided; and a situation that an automobile driver cannot hear an incoming call sound of a mobile phone due to the noises is avoided.

Description

[0001] The present invention is a divisional application of a patent whose application number is 201310181044.4, the application date is May 15, 2013, and the invention name is "vehicle volume control system". technical field [0002] The invention relates to the audio field, in particular to a vehicle volume control system. Background technique [0003] 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. [0004] However, due to the existence of many noise sources during the passage of automobiles, such as construction sit...

Problems solved by technology

[0004] 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 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
