Abstract

The embodiment of the invention discloses a volume adjustment method and device for electrical equipment, electrical equipment and media. The method includes: during the playback process of the electrical equipment, filtering the sound box audio signal in the audio signal received by the microphone to obtain the environmental audio signal; analyzing the frequency characteristics of the environmental audio signal, and judging the frequency characteristics of the environmental audio signal Whether there is a target audio signal of the user; if the target audio signal exists, adjust the volume of the electrical equipment according to the loudness of the target audio signal. By adopting the above technical solution, the intelligent detection of the user's voice in the environment is realized, and the volume of the electrical equipment is adjusted according to the voice.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of control, and in particular, to a volume adjustment method and device for electrical equipment, electrical equipment and media. Background technique [0002] With the development of science and technology, the intelligentization and humanization of electrical equipment has become a common concern of people. The intelligentization and humanization of electrical equipment provide great convenience for people's operation. [0003] Among them, the setting of the volume of the electrical equipment greatly affects the user experience. Take a TV as an example. When the volume of the TV is set high, if the user needs to talk or answer a phone call, he needs to manually turn down the volume so as not to disturb the conversation. Sometimes it is easy to miss an incoming call even when the phone rings low or is set to vibrate mode. Therefore, the intelligent detection method can automatica...
