The reflection cone 300 is arranged in the installation cavity and is positioned at the sound outlet side of the loudspeaker 200, a gap for sound transmission is formed between the reflection cone 300 and the loudspeaker 200, the side sound outlet hole 110 is communicated with the gap, and sound emitted by the loudspeaker 200 is transmitted to the side sound outlet hole 110 through the reflection cone 300, so that side sound outlet is realized.

The sound propagation direction is changed by the reflection cone 300, and the side sound output of the speaker is realized. The reflecting cone 300 has two functions, namely, changing the propagation direction of sound and guiding the sound having changed direction to the side sound outlet 110 to realize side sound.

The grille 400 is connected between the reflector cone 300 and the loudspeaker 200, and the grille 400 surrounds the sound in a lateral propagation direction for one circle, that is, the grille 400 surrounds the sound outlet of the loudspeaker 200 for one circle, and the front cavity 120 is formed among the loudspeaker 200, the grille 400 and the reflector cone 300. The dust screen 500 is provided on the grill 400.

In some embodiments of the present application, the dust screen 500 is adhered to the outer side of the grille 400, for example, by double sided tape.

During installation, the double faced adhesive tape is firstly adhered on the grille 400, paper is coated on one side of the double faced adhesive tape, then the dustproof net 500 is adhered around the grille 400 for one circle, the installation is convenient, the grille 400 also plays a role of supporting framework for the dustproof net 500, and the structure is reliable.

Taking the case that the grill 400 is composed of a plurality of posts 410, a double sided tape is wound around the outer sides of the plurality of posts 410 for one round, and then the dust screen 500 is stuck to the posts 410.

In some embodiments of the present application, the upright column 410 and the reflection cone 300 are integrally formed, a groove (not shown) is correspondingly formed on the loudspeaker 200, and when assembled, one end of the upright column 410 is inserted into the groove and fixed, so that the fixed assembly between the reflection cone 300 and the loudspeaker 200 can be realized.

The grooves on the one hand help to improve the reliability of the mounting of the uprights 410 and on the other hand act as mounting presets.

In other embodiments, the pillar 410 may be formed integrally with the horn 200, and the reflecting cone 300 (specifically, the extending portion 320) may be correspondingly provided with a groove, so that the reflecting cone 300 and the horn 200 can be fixedly assembled.

In some embodiments of the present application, one end of the upright 410 is fixed in the groove by heat fusion or screws, so that the installation is convenient, and the structure is reliable.
