Abstract:
A sound-generating device, a display device, a sound-generating controlling method, and a sound-generating controlling device are provided. The sound-generating device includes: a reflection plate which includes a first sound wave reflection face arranged towards a first direction; a plurality of main loudspeakers, the plurality of main loudspeakers are distributed in an array in a preset three-dimensional space, and the preset three-dimensional space is located at one side of the first sound wave reflection face towards a first direction; the plurality of main loudspeakers include first main loudspeakers with a sound-generating direction towards the first direction, and second main loudspeakers with a sound-generating direction towards a second direction, the second direction is an opposite direction of the first direction; and the sound waves emitted by the second main loudspeakers are transmitted to the first sound wave reflection face and can be reflected by the first sound wave reflection face.
