Abstract

The invention provides an audio output device and a sound leakage elimination method thereof. The audio output apparatus includes a processing unit, a first audio output unit, and a second audio output unit. The processing unit is used for generating a second audio file based on the first audio file and the parameter adjustment value; the processing unit is used for controlling the first audio output unit to play a first audio file to generate a first audio, and synchronously controlling the second audio output unit to play a second audio file to generate a second audio, wherein the first audio is used for being transmitted to ears of a user to be listened to by the user, and the second audio is used for eliminating audio leaked to the outside of the audio output equipment in the process that the first audio is transmitted to the ears of the user. Therefore, the sound leakage is avoided.

Description

technical field [0001] The present application relates to an audio output device, in particular to an audio output device and a sound leakage elimination method thereof. Background technique [0002] When the headset and the mobile phone are talking, you don’t want the other party’s voice to leak out and be heard by the people around you. When listening to music or watching videos, there should be no sound leakage, so as not to affect other people around you. Today's audio system products, including earphones and mobile phones, often have sound leakage when talking, listening to music or watching videos. For example, bone conduction headphones, when the volume of headphones is high, there will be sound leakage. Since the earpiece of the full-screen mobile phone is very small, the earpiece will be tilted upwards, resulting in obvious sound leakage. At present, there is no similar technology to solve the sound leakage problem. Contents of the invention [0003] The purpos...
