Problems solved by technology

However, sometimes some players participating in the game are actually next to each other. Once one of them wants to speak to a player who is farther away, the sound he makes will pass through the player's voice because he is too close to another player. The handheld device sends back, causing the same voice content to be sent and played repeatedly, resulting in unexpected sound

Abstract

A sound canceling method is suitable for an electronic device, wherein the electronic device can be connected with a sound playing device and includes a microphone. The method for eliminating sound of the present invention comprises the following steps: receiving the first input sound through a microphone to obtain a first input sound signal; recording the first input sound signal, and sending the first input sound signal to a sound playback device; receiving the first input sound signal through a microphone; The sound playing device sends out the second input sound according to the first input sound signal to obtain the second input sound signal; calculate the time difference between the first input sound signal and the second input sound signal; and, according to the time difference and the first input sound signal to filter out the second input sound signal.

Description

technical field [0001] The present invention relates to a method for eliminating sound and an electronic device for executing the method, in particular, a method for eliminating sound from other devices and an electronic device for executing the method. Background technique [0002] With the gradual upgrade of handheld devices, many video games can be executed on mobile phones or tablet computers, and due to the rapid development of network communication, many players can make voice calls with other players participating in the game through network synchronization during the game . However, sometimes some players participating in the game are actually next to each other. Once one of them wants to speak to a player who is farther away, the sound he makes will pass through the player's voice because he is too close to another player. The handheld device sends back, causing the same voice content to be sent and played repeatedly, resulting in unexpected sounds. [0003] There...
