Problems solved by technology

However, the existing technology adopts a one-size-fits-all control method, that is, the output volume of all the speakers in the compartment is adjusted to the same extent according to the collected sound signals, and it cannot be adjusted in different ranges according to the sound source positions of the collected sound signals. The output volume of the speakers distributed throughout the cabin, the user experience is not good

Abstract

A volume control method, device and system for on-board speakers. By acquiring a sound signal picked up by each on-board microphone, and according to the different influencing weight of each on-board microphone with respect to each on-board speaker, the influencing weight being determined by the distance between that on-board microphone and that on-board speaker, the method adjusts the output volume of on-board speakers which are distributed in different positions within the car, to different extents. The invention can adjust, according to the positions of the sound sources corresponding to the sound signals collected by the microphones, the output volume of on-board speakers distributed in different positions within the car to different extents, effectively improving user experience.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a volume control method, device and system for a vehicle-mounted speaker. Background technique [0002] With the steady development of the automobile industry, the types of on-board electronic devices installed in the car are becoming more and more abundant, such as on-board navigation equipment, on-board warning equipment, and on-board multimedia entertainment equipment. And multimedia entertainment sound, which enables people to drive more conveniently, safely and comfortably. However, in some cases, the output volume of the car speaker is too high, which will bring a lot of inconvenience. In the traditional way, people need to manually adjust the output volume of the speaker, which is troublesome to operate, and it is easy to distract the driver's attention, which increases the driving force. of danger. [0003] The appearance of the volume control device of the car spea...
