[0020] Therefore, the detailed description of the embodiment of the utility model provided in the following combined with the drawings is not intended to limit the scope of the claimed utility model, but only represents the selected embodiment of the utility model, based on the embodiment in the utility model, all other embodiments obtained by the ordinary skill in the art without making creative labor belong to the scope of the protection of the utility model.

[0021] Embodiment 1

[0022] AsFigures 1-5 As shown, the vibration-cancelling sound production structure provided by the embodiment is composed of a speaker box 10 and two speaker bodies 20, and the two speaker bodies 20 are symmetrically arranged on the speaker box 10 to realize vibration cancellation.

[0023] Specifically, the speaker box 10 comprises an outer frame 11, an audio outlet 101 arranged on the front side of the outer frame 11, a cover plate 12 arranged on each of the upper and lower sides of the outer frame 11, and an inner frame 13 arranged in the outer frame 11 and communicating with the audio outlet 101.

[0024] The speaker box 10 is provided with a mounting hole 102 on each of the opposite sides, and the two mounting holes 102 are in corresponding and communicating relationship, the mounting hole 102 communicates with the audio outlet 101, and the mounting hole 102 extends from the cover plate 12 into the outer frame 11.

[0025] The speaker body 20 is arranged in the mounting hole 102, and the diaphragms 21 on the two speaker bodies 20 are arranged towards each other, i.e., the vibration directions of the two diaphragms 21 are opposite.

[0026] Further, the speaker box 10 is provided with a partition plate 30 arranged between the two mounting holes 102, and the two speaker bodies 20 are arranged on the opposite sides of the partition plate 30, respectively, and there is a spacing between the speaker body 20 and the partition plate 30, the partition plate 30 is provided with a plurality of through holes 31, and the two mounting holes 102 are communicated through the through holes 31, and the shape of the through hole 31 can be circular, square, etc.
