Title:
AUDIO PLAYER, METHOD FOR REDUCING SOUND DISTORTION, AND SOUND DISTORTION REDUCTION MODULE
Document Type and Number:
WIPO Patent Application WO/2020/206629
Kind Code:
A1
Abstract:
Disclosed are an audio player, a method for reducing sound distortion, and a sound distortion reduction module. The audio player comprises an electromagnetic drive sound generation unit, an audio signal receiver, and a sound distortion reduction module, wherein both the audio signal receiver and the sound distortion reduction module are electrically connected to the electromagnetic drive sound generation unit; the audio signal receiver is used for receiving an audio signal and inputting the audio signal into the electromagnetic drive sound generation unit; and the sound distortion reduction module is used for generating an alternating-current bias signal and inputting the alternating-current bias signal into the electromagnetic drive sound generation unit. The audio player disclosed in the present invention is provided with a sound distortion reduction module to generate an alternating-current bias signal, and the alternating-current bias signal is superimposed onto an audio signal, such that during the process of an input audio signal being converted from a positive electrode into a negative electrode or from a negative electrode into a positive electrode, non-linear factors generated due to magnetic hysteresis can be reduced, and the problem of harmonic distortion, appearing near a conversion point of the positive electrode and the negative electrode, of the audio signal can be effectively improved, thereby improving the sound quality thereof.
