Audio signal conversion device and method

Abstract

The embodiment of the invention provides an audio signal conversion device and method, and relates to the technical field of signal processing. The device comprises an audio acquisition and processingmodule and an amplification and output module; the amplification and output module is connected with the audio acquisition and processing module; the output end of the amplification and output moduleis used for being contacted with the skin of a user; the audio acquisition and processing module is used for judging whether a pre-set audio signal is matched with an acquired audio signal or not, and if so, generating a characteristic waveform signal having the corresponding relationship with the audio signal to the amplification and output module; and the amplification and output module is usedfor amplifying the current value of the characteristic waveform signal to obtain the amplified characteristic waveform signal, and outputting the amplified characteristic waveform signal through an output end. The amplified characteristic waveform signal can generate the electrical sensation corresponding to the waveform of the characteristic waveform signal at the skin contact position of the user; therefore, due to the audio acquisition and processing module, the user can realize audio perception through touch; and thus, the user has better perception experience on social formation.

Description

technical field [0001] The present invention relates to the technical field of signal processing, in particular to an audio signal conversion device and method. Background technique [0002] Deaf-blind people have difficulty perceiving social forms through speaking and hearing because they themselves cannot hear and speak. [0003] At present, many deaf-mute people use sign language to communicate with other deaf-mute people or normal people, so that many deaf-mute people can form a perception of social forms through sign language. However, only through sign language, the perception mode of the deaf-mute is single, making it impossible for many deaf-mute people to form a better perception experience of social forms from the perspective of multi-modal perception. [0004] Therefore, how to enable the deaf-mute to form a better perception experience of social forms is currently a major problem in the industry. Contents of the invention [0005] In view of this, the purpose...
