Embodiment Construction

[0027] The technical solution provided by the present invention is: two or more loudspeakers are arranged respectively along the four edges of the display screen (display plane) outer frame of the TV set in the horizontal direction and the vertical direction, and these loudspeakers are divided into two groups according to the direction: the horizontal direction group and vertical orientation group. At the same time, by controlling and selecting a speaker in the horizontal direction group and a speaker in the vertical direction group to emit sound, the position of the sound emitting speaker can be closer to the position of the main sound source in the image of the display device.

[0028] 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 a...

Abstract

The invention provides a method for locating sound and a system thereof, wherein the method comprises the following steps: firstly, a display device receives sound signals, analyzes horizontal position information and vertical position information of a main sound source according to the main sound source location information in the sound signals, secondly, the display device selects one loudspeaker to sound from two or more than two loudspeakers arranged on the upper portion of the display plane of the display device or two or more than two loudspeakers on the lower portion of the display plane according to the horizontal location information of the main sound source, and selects one of the loudspeaker to sound from two or more than two loudspeakers arranged on the left portion of the display plane or two or more than two loudspeakers arranged on the right portion of the display plane of the display device according to the vertical location information of the main sound source.

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...
