Abstract

The invention discloses a sound input / output system and a volume output adjusting method thereof, which are used for automatically adjusting the volume of sound listened by a speaker according to the speaking sound of the speaker. The sound input / output system comprises a sound processor and a volume adjuster, wherein the sound processor is used for resolving the input sound received by a receiver, and the volume adjuster is used for adjusting the output sound of a loudspeaker according to a sound change value acquired by the sound processor. When the speaker changes the speaking volume along with the environment or the listened input sound, the sound processor can resolve the sound change value of the input sound, and then adjust the volume of the output sound according to the sound change value.

Description

technical field [0001] The present invention relates to a loudspeaker sound adjustment technology, and in particular to a system and method for automatically adjusting volume. Background technique [0002] In today's era of rapid technological development, portable electronic devices have become an indispensable part of modern people's daily life. For example, mobile phones, with their features such as thin, light, small, and easy to carry, allow modern people to communicate with others by phone anytime, anywhere, which is quite convenient. [0003] However, with existing mobile phones, when the general user uses the mobile phone to communicate with other people, he must put the calling end of the mobile phone close to the ear to hear the voice of the caller on the other side. And when the user is in a noisy environment, such as the side of the road, because of the noisy sound of automobiles and motorcycles, or the voice of the call from the other party is too low, the natu...
