Abstract

The invention discloses a sound based volume adjustment device. The device comprises a signal processing module, a noise acquisition module, a gain module, a pattern base, an input module and an output module. The noise acquisition module is used for acquiring a noise signal, the signal processing module performs sound analytical calculation according to an input audio signal and the noise signal, and the gain module is used for automatically adjusting volumes. The invention further provides a sound based audition product, and the sound based volume adjustment device is arranged in the product. The invention further provides a sound based volume adjusting method, and the method includes the steps of step one, playing input audio and acquiring the noise signal; step two, performing sound analysis if the noise signal exceeds a preset valve value; and step three, automatically adjusting the volume of the played audio.

Description

technical field [0001] The invention relates to a volume adjustment device, product and method, in particular to a volume adjustment device, product and method capable of automatically adjusting volume according to ambient noise. Background technique [0002] Today's radios, tape recorders, jukeboxes, CDs, DVDs, MP3s, televisions, computers and other visual and auditory-related products continue to penetrate into everyone's life and become the electrical products closest to personal life. The purpose of hearing-related products is to provide sound effects that meet the requirements for listening lovers. To achieve this goal, audio signals need to be processed such as power amplification. [0003] The structure of existing listening equipment can be found in figure 1 As shown, it contains at least the following basic parts: input module, volume regulator, gain module and output module. The input module is used to receive various audio files, such as the equipment for readin...
