Embodiment Construction

[0020] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0021] In the embodiment of the present invention, according to the corresponding relationship between the volume level and the volume decibel value, the volume decibel value corresponding to each level of volume can be calculated, and then the volume decibel value is adjusted to obtain a suitable volume decibel value, and the adjusted volume decibel value is obtained. The volume decibel value is converted into a volume value in hexadecimal form.

[0022] figure 1 The implementation process of the volume control provided by the embodiment of the present invention is shown, and the details are as f...

Abstract

The invention provides a method, a system and an electric appliance for volume control, belonging to the technical field of electric appliances. The method comprises the following steps: first, to figure out the decibel values corresponding to each volume level according to the corresponding relationship between the volume level and the decibel value; second, to adjust the volume values corresponding respectively to each volume level, thus enabling each of the adjusted volume values divide exactly the precision of the volume processing hardware; third, to change the adjusted volume values intonumerical volume values in the form of hexadecimal system. The invention has the advantages that the embodiment can figure out the decibel values corresponding to each volume level according to the corresponding relationship between the volume level and the decibel value, and adjust the volume values, hence avoiding high complexity and low efficiency in volume selection in the prior art.

Description

technical field [0001] The invention belongs to the field of electric appliances, and in particular relates to a volume control method, system and electric appliances. Background technique [0002] At present, electric appliances with volume control such as televisions and set-top boxes all have digital volume control systems, and the digital volume control system can be controlled by using the remote controller of the electric appliance or the buttons provided on the electric appliance to control the volume of the electric appliance. In the past, in electrical appliances with volume control, the digital volume control system used a certain number of sound levels to control the volume. For example, 50 levels and 100 levels were used to control the volume on the TV. Press the button to increase the volume level to increase the actual volume. Due to the relatively low precision of the volume processing hardware such as the previous audio chip, the volume decibel value between...
