Description

technical field

[0001] The invention belongs to the field of display technology, and in particular relates to the sound reproduction technology of a display device. Background technique

[0002] Existing display devices not only provide image information, but also provide more and more rich sound information to users. Users have higher and higher requirements for the image quality of display devices, and at the same time, the requirements for sound quality are also higher and higher. .

[0003] Taking a TV as an example, the reproduction of TV signal sound is generally realized through a sound box on the TV. The more common method at present is: respectively install a loudspeaker on the left and right sides of the TV casing, and reproduce the sound corresponding to the image through the cooperation of the left and right loudspeakers, thereby realizing the synchronous reproduction of sound and image. In high-quality TV equipment, sometimes using a common speaker is often no...
