Problems solved by technology

[0003] For example, the user started to watch TV after dinner. The environment at that time was not very quiet, and the volume of the TV was turned on relatively loudly. The volume of the TV is too loud, but usually the user has adapted to the volume of the TV, so there is no awareness of lowering the volume, which will have a certain impact on other users around
Correspondingly, when the sound intensity of the surrounding environment changes from low to high, the user cannot hear the sound of the TV because the volume of the TV is too low, and the existing volume adjustment method is not flexible enough.

Embodiment Construction

[0050] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0051] refer to figure 1 , propose an embodiment of the method for automatically controlling the volume of the present invention, including:

[0052] Step S101, collecting the sound intensity value of the environment;

[0053] The audio playback device of this embodiment can be equipment such as TV, MP3, MP4 and DVD player, when the function of automatically controlling the volume according to the sound intensity of the environment is turned on, the audio playback device collects the sound intensity value of the surrounding environment. When collecting the sound intensity value of the environment, the collection time interval and the collection time length can be flexibly set according to the needs. For example, the time length can be set longer during the day and shorter at night.

[0054] Step S102, according to t...

Abstract

The invention discloses an automatic volume control method. The automatic volume control method comprises the following steps of: collecting a sound intensity value of an environment; matching a corresponding first volume value in a preset volume-sound intensity function curve according to the sound intensity value; and adjusting the volume of audio playing equipment to the first volume value. The invention further provides a corresponding automatic volume control device. According to the automatic volume control method, device and equipment, the volume of the audio playing equipment can be automatically controlled according to the change of the environment sound intensity.

Description

technical field [0001] The invention relates to the field of audio playback, in particular to a method, device and equipment for automatically controlling volume. Background technique [0002] After the TV volume is adjusted by the user, its volume will remain unchanged. The sound intensity of the environment where the TV is located will vary in different time periods, and sometimes even vary greatly. [0003] For example, the user started to watch TV after dinner. The environment at that time was not very quiet, and the volume of the TV was turned on relatively loudly. The volume of the TV is too loud, but usually the user has adapted to the volume of the TV, so there is no awareness of lowering the volume, which will have a certain impact on other users around. Correspondingly, when the sound intensity of the surrounding environment changes from low to high, the user cannot clearly hear the sound of the TV because the volume of the TV is too low, and the existing volume ...
