Abstract

The invention relates to an automatic tuning device which comprises an audio input module, a volume control module and an audio output module, wherein the volume control module is connected with the audio input module; and the audio output module is connected with the volume control module. The automatic tuning device also comprises a noise detection module, a volume constant input module and a volume setting module which is connected with the noise detection module and the audio input module. The invention also relates to an automatic tuning method and a multimedia player, wherein the multimedia player comprises the automatic tuning device. Through the invention, the function of automatically adjusting the volume according to the noise decibels of different environments is realized without needing a user to manually adjust the volume time after time, thus the automatic tuning device is convenient to use and enables the user to better enjoy audio files such as music and the like.

Description

【Technical field】 [0001] The invention relates to the field of portable electronic equipment, in particular to an automatic tuning device, method and multimedia player. 【Background technique】 [0002] At present, there are more and more types of portable electronic devices, especially, more and more types of portable multimedia players, and their applications are becoming more and more extensive. In order to hear audio files in different scenarios, more and more audio playback hardware is used, such as earphones, earpieces, external speakers, stereos, and the like. However, the audio playback hardware of each multimedia player needs to manually adjust the volume. No matter in what environment, as long as the user does not adjust the volume, the volume on these portable electronic playback devices will remain unchanged. Since people's environment is constantly changing, such as in leisure facilities, stations, or public transportation, people usually need to manually adjust ...
