[0025] DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings of the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0027] Please refer to Figs. 1-3The cavity chamfered sound box shell can include the following.

[0028] The rectangular back plate 1 is equipped with short plates 2 on both side edges, and long plates 3 on the top and bottom edges;

[0029] The inner wall of the two long plates 3 is equipped with loudspeaker panels 4, and the connection between the loudspeaker panels 4 and the short plates 2 is equipped with inclined plates 5;

[0030] The inclined plate 5 is provided with a reverse phase hole 51 in the middle.

[0031] Here, the wall edge of one side of the loudspeaker is chamfered, compared with the triangular reflection area that may be formed by the traditional right-angle edge, the chamfering is realized by assembling the inclined plate 5, which effectively makes the reflection path of the sound wave in the cavity intensive and regular, thereby effectively improving the outdoor sound quality without increasing the cavity, without reducing the rear-end device of the loudspeaker, and without significantly changing the specifications of the sound box and internal devices.
