Abstract

The invention belongs to the field of vehicle technology, and specifically provides a volume adjustment method, device, system, audio playback equipment and vehicle, aiming to solve the technical problem of complicated volume adjustment. For this purpose, the volume adjustment method provided by the present invention mainly includes the following steps: obtaining the average volume of the audio file; judging whether the average volume is within a preset volume range and selectively adjusting the output volume of the audio file according to the judgment result; wherein, the preset Set the volume range to depend on the target output volume entered by the user. Based on the above steps, the present invention can ensure that the output volume of the audio file always meets the user's expected output volume, which not only improves the user experience, but also avoids driving safety hazards caused by the user's manual volume adjustment.

Description

technical field [0001] The invention belongs to the technical field of vehicles, and in particular relates to a volume adjustment method, device, system, audio playback equipment and a vehicle. Background technique [0002] The existing car audio system does not adjust the volume of the music itself. When it outputs music, the audio parameters such as the peak volume and average volume of the music are constant, but there are large differences in the volume parameters of different music, such as rock music. Generally, the volume is higher than that of lyrical music. When switching music, the user has to manually adjust the volume to ensure that the output volume meets the user's expectations. Further, when the driver manually adjusts the volume, the driver's attention will be distracted, causing a certain degree of driving safety hazard. [0003] Correspondingly, there is a need in the art for a new volume adjustment method to solve the above problems. Contents of the inv...
