[0028] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0029] Please refer to Figures 1 to 8 , sound unit, including:

[0030] Basin stand 1;

[0031] The sound diaphragm 2 includes an external fixing portion 23, and the external fixing portion 23 has an external edging 24 for connecting to the outer wall of the basin frame 1. The external edging 24 is annular as a whole, and the inner wall surface of the external edging 24 is provided with at least one first convex ring structure 241, and a first glue-containing area 251 is formed between the first convex ring structure 241 close to the external fixing portion 23 and the external fixing portion 23, and a second glue-containing area 252 is formed below the first convex ring structure 241 away from the external fixing portion 23.

[0032] From the above description, it can be seen that the beneficial effect of the utility model is that the setting of the outer edge 24 on the outer fixing part 23 can increase the bonding area between the sound membrane 2 and the basin frame 1, thereby reducing the risk of separation between the basin frame 1 and the sound membrane 2; more importantly, the setting of the first convex ring structure 241 on the outer edge 24 can form a first glue-containing area 251 and a second glue-containing area 252 between the basin frame 1 and the outer edge 24, thereby increasing the total amount of glue that can be accommodated in the gap between the basin frame 1 and the outer edge 24, thereby further improving the stability of the connection between the basin frame 1 and the sound membrane 2, and further reducing the risk of separation between the basin frame 1 and the sound membrane 2.

[0033] Furthermore, the first convex ring structure 241 abuts against the basin frame 1 .

[0034] It can be seen from the above description that the first convex ring structure 241 abuts against the outer wall of the basin frame 1, so that the first glue containing area 251 can be closed, thereby better retaining the glue.

[0035] Furthermore, there are a plurality of first convex ring structures 241 , and a third adhesive containing area 253 is formed between two adjacent first convex ring structures 241 .

[0036] It can be seen from the above description that the existence of the third glue containing area 253 allows the gap between the basin frame 1 and the outer edge 24 to retain more glue.

[0037] Furthermore, the outer fixing portion 23 and the outer edge 24 are an integral structure formed by integral injection molding.

[0038] It can be seen from the above description that the sound membrane 2 is easy to process and has a low manufacturing cost.

[0039] Furthermore, the outer fixing portion 23 also has an inner rim 26 for connecting to the basin frame 1 , and the inner rim 26 is annular as a whole. The inner rim 26 , the outer rim 24 and the outer fixing portion 23 together constitute a receiving groove for receiving at least a part of the basin frame 1 .

[0040] From the above description, it can be seen that the setting of the inner edging 26 on the outer fixing part 23 can further increase the bonding area between the sound membrane 2 and the basin frame 1, thereby reducing the risk of separation of the basin frame 1 and the sound membrane 2; in the process of assembling the sound membrane 2 and the basin frame 1, the receiving groove can pre-position the basin frame 1, which is beneficial to improve the consistency of the assembly of the basin frame 1 and the sound membrane 2 and improve the production yield.

[0041] Furthermore, the outer wall surface of the inner edge 26 is provided with at least one second convex ring structure 261, and a fourth glue-containing area 271 is formed between the second convex ring structure 261 close to the outer fixing part 23 and the outer fixing part 23, and a fifth glue-containing area 272 is formed below the second convex ring structure 261 away from the outer fixing part 23.

[0042] From the above description, it can be seen that the setting of the second convex ring structure 261 on the inner edge 26 can form a fourth glue-containing area 271 and a fifth glue-containing area 272 between the basin frame 1 and the inner edge 26, thereby increasing the total amount of glue that can be accommodated in the gap between the basin frame 1 and the inner edge 26, thereby further improving the stability of the connection between the basin frame 1 and the sound membrane 2, and further reducing the risk of separation of the basin frame 1 and the sound membrane 2.

[0043] Furthermore, the second convex ring structure 261 abuts against the basin frame 1 .

[0044] It can be known from the above description that the second convex ring structure 261 abuts against the inner side of the basin frame 1, so that the fourth glue containing area 271 can be closed, thereby better retaining the glue.

[0045] Furthermore, there are a plurality of second convex ring structures 261 , and a sixth adhesive containing area 273 is formed between two adjacent second convex ring structures 261 .

[0046] It can be seen from the above description that the existence of the sixth glue containing area 273 allows the gap between the basin frame 1 and the inner edge 26 to retain more glue.

[0047] Furthermore, the outer fixing portion 23 and the inner edge 26 are an integral structure formed by integral injection molding.

[0048] It can be seen from the above description that the sound membrane 2 is easy to process and has a low manufacturing cost.
