[0027] During installation, the grille 40 is installed on the sound-emitting side of the speaker. Figure 4As shown, since a detachable gasket 20 is installed on the top ring structure 11 of the basin frame 10, and a soft bonding layer 30 is fixed on the side of the gasket 20 away from the basin frame 10, the sound-emitting side of the speaker and the sound-gathering ribs 41 of the mesh cover 40 can be sealed by the gasket 20 and the soft bonding layer 30, avoiding the presence of a gap between the sound-gathering ribs 41 of the mesh cover 40 and the speaker, and all the sounds emitted by the speaker can be transmitted to the external environment through the mesh cover 40, thereby improving the sound quality. The sound-emitting device of the utility model solves the problem that a gap between the mesh cover and the speaker easily affects the sound quality.

[0028] In the present invention, a height adjustment structure is provided between the gasket 20 and the top ring structure 11 for adapting to different distances between the mesh cover 40 and the sound-emitting side of the speaker, thereby improving versatility.

[0029] Specifically, the top ring structure 11 includes a load-bearing ring portion 111, a retaining ring portion 112 fixed to the load-bearing ring portion 111 on the side of the basin bottom structure 12 away from the basin frame 10, and a mounting portion arranged on the outer peripheral side of the load-bearing ring portion 111. The mounting portion is used to realize the installation and fixation of the speaker. Usually, the mounting portion includes at least two mounting ears 113 spaced apart along the peripheral side of the load-bearing ring portion 111. Of course, the mounting portion can also be an extension plate arranged on the peripheral side of the load-bearing ring portion 111; the height adjustment structure includes a washer connection structure arranged on the gasket 20, a retaining ring connection structure arranged on the retaining ring portion 112, and a load-bearing ring connection structure arranged on the load-bearing ring portion 111. The washer connection structure can be connected to the retaining ring connection structure and the load-bearing ring connection structure respectively. Since the retaining ring portion 112 is fixed to the side of the supporting ring portion 111 away from the basin bottom structure 12 of the basin frame 10, and the retaining ring portion 112 is provided with a retaining ring connecting structure and the supporting ring portion 111 is provided with a supporting ring connecting structure, when the gasket connecting structure of the gasket 20 is respectively connected to the retaining ring connecting structure and the supporting ring connecting structure, the distance between the gasket 20 and the soft bonding layer 30 and the sound-emitting side of the speaker can be adjusted, so that the gasket 20 and the soft bonding layer 30 adapt to the height difference between the sound-gathering rib 41 of the mesh cover 40 and the speaker.

[0030] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 and Figure 6It can be seen that the gasket 20 includes a ring body 21; the gasket connection structure includes at least two hooks 22 arranged at intervals along the circumference of the ring body 21 on the lower ring end face of the ring body 21, and the hook parts of the at least two hooks 22 are both arranged toward the inner ring side of the ring body 21 or are both arranged toward the outer ring side of the ring body 21, and a limiting step 221 is formed between the side of each hook 22 away from its hook part and the lower ring end face of the ring body 21; the load-bearing ring connection structure includes at least two plug-in holes 14 arranged in a one-to-one correspondence with the at least two hooks 22, and at least two plug-in holes 14 are arranged on the load-bearing ring part 111 on the inner ring side of the retaining ring part 112, and a limiting protrusion 141 is respectively provided on the inner side wall of each plug-in hole 14; the retaining ring connection structure includes at least two card interfaces 15 arranged in a one-to-one correspondence with the at least two hooks 22, and at least two card interfaces 15 are arranged on the retaining ring part 112.
