Description

technical field

[0001] The invention relates to the field of precision molding, in particular to an audio precision molding panel with volume detection function. Background technique

[0002] The car's car audio is installed inside the front face of the cab, and the front panel of the cab is provided with a car audio packaging panel. The panel is mainly equipped with an audio control panel, a speaker outlet, etc. Most drivers Keen to play their favorite music while driving, and often set the volume very high, which leads to the fact that the driver cannot hear the sound warning information from the outside in the closed environment of the car, which is a very dangerous driving behavior, so it is necessary to Let the driver know the loudness of the current noise in time, and reduce the volume appropriately. Contents of the invention

[0003] The technical problem mainly solved by the present invention is to provide a sound precision molded panel with volume detection funct...
