1. An audio output device, comprising a processor, a first speaker, and a second speaker, wherein
the processor is electrically coupled with the first speaker and the second speaker respectively;
the processor is configured to generate a second audio file based on a first audio file and a parameter adjustment value; and
the processor is configured to control the first speaker to play the first audio file to generate a first audio and synchronously control the second speaker to play the second audio file to generate a second audio, wherein the first audio is transmitted to a user for the user to listen, and the second audio is used to eliminate an audio leaked to an outside of the audio output device during transmission of the first audio to the user;
wherein the processor is configured to: determine the audio that will leak to the outside of the audio output device based on the first audio file and a playback parameter of the first audio file, determine the parameter adjustment value based on the first audio and the audio leaked to the outside of the audio output device, and generate the second audio file based on the first audio file and the parameter adjustment value.
