Problems solved by technology

When the sound of the external environment changes and affects the effect of watching TV, the user can only adapt to the change of the environment by resetting the control parameters, which requires constant operation of the remote control to adjust the volume, which is very inconvenient
[0003] At present, AVC (automatic volume control), the technology for automatic volume control of TV, is mainly aimed at the size of the internal sound signal of the TV, and automatically adjusts the volume, and is not suitable for volume adjustment when the sound of the external environment changes.

Embodiment Construction

[0029] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0030] The embodiment of the present invention judges whether the sound of the surrounding environment is noise, if so, calculates the volume adjustment value of the terminal, and adjusts the volume, so that the user can enjoy the program without being affected by the environmental sound.

[0031] see figure 1 , the main method flow for adjusting the volume in this embodiment is as follows:

[0032] Step 101, the terminal collects surrounding environmental sounds, and extracts the characteristic spectrum of the surrounding environmental sounds;

[0033] Step 102, comparing the characteristic spectrum of the surrounding environment sound with a preset noise characte...

Abstract

The invention discloses a method and a device for regulating volume, and a digital terminal. The method comprises the following steps of: acquiring sounds in a peripheral environment, and extracting a characteristic frequency spectrum of the sounds; comparing the characteristic frequency spectrum of the sounds in the peripheral environment with a preset noise characteristic frequency spectrum library, and judging whether the sounds are noise or not; if the sounds in the peripheral environment are noise, measuring and acquiring a decibel value of the sounds in the peripheral environment by the terminal; calculating and acquiring a volume value which is suitable for an environment according to the decibel value of the sounds; and regulating the volume of the terminal according to the acquired volume value which is suitable for the environment. The invention also discloses the device for implementing the method and the digital terminal.

Description

technical field [0001] The present invention relates to the technical field of digital terminals, in particular to a method and device for adjusting volume and a digital terminal. Background technique [0002] The current method for adjusting the volume of terminals such as televisions is mainly to control the size of the volume through artificial setting by the operator. When the sound of the external environment changes and affects the effect of watching TV, the user can only adapt to the change of the environment by resetting the control parameters, which requires constant operation of the remote controller to adjust the volume, which is very inconvenient. [0003] AVC (automatic volume control), the current technology for automatic volume control of TVs, is mainly aimed at automatically adjusting the volume of the internal sound signal of the TV, and is not suitable for volume adjustment when the sound of the external environment changes.
