Automobile-based random sound source automatic sound control device

Abstract

The invention discloses an automobile-based random sound source automatic sound control device, which comprises an environmental analysis module, an audio management module and a play control module, wherein the environmental analysis module is used for analyzing noise information of the automobile; the audio management module is used for classifying sound sources in the automobile and configuring a corresponding play priority for a sound source of a different type according to the classification information; and the play control module is used for automatically adjusting play parameters of the sound source according to the noise information of the automobile and the play priority for the sound source. Thus, the play parameters of the sound source can be adaptively adjusted according to the environment in the automobile and the sound source configuration information in the automobile, comfort of user experience is enhanced, and multi-scene requirements of an automobile-mounted system are met.

Description

technical field [0001] The invention relates to the technical field of wireless communication for vehicles, in particular to a vehicle-based automatic sound control device for random sound sources. Background technique [0002] With the development of multimedia and the Internet of Vehicles, the functions of the car and the machine are increasing, and sound as a medium is becoming more and more important, such as figure 1 As shown, the traditional car-machine system in the prior art uses different functional modules to distinguish sounds, such as navigation module, bluetooth module, FM module, etc., and uses dedicated hardware to process each sound source. With the improvement of hardware integration, such as figure 2 As shown, the smart vehicle system in the prior art integrates hardware modules into the main control chip, and the sound of each functional module is also output through the main control. [0003] However, due to the limited sound processing mode of the hard...

Problems solved by technology

[0003] However, due to the limited sound processing mode of the hardware, it is completely implemented according to the design before leaving the factory. The sound processing of many after-installed software and multiple channels from the same source is not satisfactory. It is very likely that sudden loud volume playback will occur at any time, which will not only damage the people in the car. It will seriously distract the driver's attention and increase the risk; in addition, it is very likely that multiple sounds will be played together, without primary or secondary, leading to important information (such as navigation sounds) being missed, seriously affecting the driving experience
