Problems solved by technology
[0011] As described above, the conventional image display device cannot correct the changing acoustic characteristics depending on the living environment of the user, and when the image display device is designed with the effect of the acoustic characteristics set, the sound in a specific area is amplified and passed through the speaker 16. The output sound signal sounds either awkward or not what you want
[0012] Therefore, it is very complicated for the user to perfect this deficiency by adjusting the sound effect he expects on the user menu through the keyboard input unit 17.
[0013] In addition, this kind of problem is mostly a bass problem. The smaller the space and the more reflection conditions in the surrounding environment, the more obvious the bass boost will be, so the sound will be louder and the clarity will be lower. Too much bass will make the sound blurred.
[0014] At this time, if the user tries to solve the problem by reducing the volume, but only reduces the overall volume, but fails to improve the bass amplification problem, that is, when this happens, most users are not very clear about what to adjust, so it is difficult Ensures that the sound is heard to the tiniest degree within the set acoustic characteristics

The invention relates to an acoustics correction device of image display device and relative method. It comprises: a keyboard input part for inputting the order of user; an acoustic sensing part for sensing and outputting sound via loudhailer after sensing the order input by keyboard input part that turning out the power resource; a memory part for memorizing the different acoustic levels as high, middle and low according to the space characters of image display device; and a control part for comparing the sensed sound with stored sound level to correct the sound character and feedback the sound signal to the sound processing part. The invention can sense the sound that reflected from the space and sense its change to automatic correct to keep sound clear, to improve the receiving quality of user.
Description
technical field [0001] The present invention relates to a sound correction device and method, in particular to a sound correction device and method of an image display device for correcting sound effects through feedback of sound output by an image display device. Background technique [0002] Usually, according to different installation environments and different living environments of users, the settings of image display devices are diversified, so the sound characteristics will also be different. In addition to the sound characteristics, different sound characteristics will also be formed due to the user's home environment. [0003] Hereinafter, a conventional image display device and its sound adjustment method will be described with reference to the accompanying drawings. [0004] Such as figure 1 As shown, it is a structural block diagram of an image display device in the conventional technology, which has the following structural features, that is, it includes: a tu...
