Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a TV set for the inability to know the actual volume of the TV, which often causes the user to adjust the volume of the TV too high, resulting in damage to the user's hearing and adverse effects on the surrounding environment. Device and method for volume setting

Embodiment Construction

[0029] figure 2 It is a flow chart of the actual volume setting of the TV set in the present invention. First, set the maximum sound pressure limit of a TV sound as the preset volume maximum value, and then detect whether the volume adjustment key is pressed. When it is detected that the key is pressed continuously, The volume value adjusted by the user is obtained; the volume value is converted into a sound pressure value and compared with the preset maximum volume value. If the sound pressure value is greater than the preset maximum volume and the user wants to increase the volume, the system does not perform the volume increase operation and ends directly; if it is not greater than the preset volume maximum or the user wants to decrease the volume, then Convert the sound pressure value into a register value and write it into the register. Then perform sound processing according to the user's instruction, and output the sound, and the sound pressure value is displayed on t...

Abstract

A setting method and device for actual volume of a television comprises a collecting element of actual volume of a television and a memory device. The memory device is used for memorizing preset maximum of actual volume of television and memorizing a correspondent relation table of actual volume and actual acoustic pressure level. The invention includes the following procedures that: a. user presses on the volume-increasing button, thus obtaining needed volume value; b. the television transforms received volume into acoustic volume levels; c. with comparison between the acoustic pressure level and the system-preset volume maximum, if the acoustic pressure level is bigger than the preset volume maximum, operation requesting volume increase will not work, or, d. writing the volume into memory device; e. implementing sound output processing; f. volume is displayed on the television screen. The invention and device can not only enable users know the sound of television and the actual sound pressure, but also protect the hearing of user and surrounding environment by limiting over high sound pressure.

Description

technical field [0001] The invention relates to a device and a method for volume setting, in particular to a device and a method for setting the actual volume of a television. Background technique [0002] At present, when the TV is adjusting the volume, the TV screen only displays the current volume value, which is generally a value between 0 and 100, and cannot tell the user the real volume of the current sound. The volume adjustment method is as follows figure 1 As shown, when it is detected that the user presses the volume key, the volume value to be adjusted must be converted and sent to the register, and the sound output will be processed, and the volume value will be displayed on the screen. [0003] Since the display is not the real sound level, the maximum limit of the sound adjustment cannot be set, because 0 to 100 is only a relative value. Different TV manufacturers, different models, and different channels, the real sound level corresponding to the value of 0 t...
