Description

technical field [0001] The invention relates to a device for switching audio files, in particular to a device for switching audio files by using a knob type digital coding switch. Background technique [0002] At present, most digital audio players use a group of keys to switch song files or folders. This group of buttons generally includes a forward switching button and a backward switching button, the selection of the front audio file is realized through the operation of the forward switching button, and the selection of the following audio file is realized through the operation of the backward switching button. Each time the forward switch button or the backward switch button is pressed, a file switch is realized. When it is necessary to switch a file that is not adjacent to the current file in position, it is necessary to continuously press the forward switch button or the backward switch button. The switch used in the existing keys is usually a mechanical elastic switc...
