[0030] 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.

[0031] Please refer to Figures 1 to 5 , a loudspeaker comprising:

[0032] A basin frame 1, wherein a pressing groove 11 is provided on the inner wall of the basin frame 1;

[0033] A yoke 2, wherein the yoke 2 is disposed in the basin frame 1, and the yoke 2 comprises a flange 21, wherein the outer wall of the flange 21 is disposed opposite to the inner wall of the basin frame 1, and a glue injection seam 3 is formed between the pressing groove 11 and the outer wall of the flange 21;

[0034] Adhesive member 4, the adhesive member 4 is arranged in the glue injection seam 3, and the adhesive member 4 is formed after the glue injected in the glue injection seam 3 is cured;

[0035] The pressing groove 11 has a first groove 111 , and the adhesive 4 forms a first convex block 41 corresponding to the first groove 111 . The inner wall of the flange 21 has a second groove 211 , and the adhesive 4 forms a second convex block 42 corresponding to the second groove 211 .

[0036] The structural principle of the utility model is briefly described as follows: the speaker described in the utility model forms an adhesive 4 by curing the glue in the glue injection seam 3, and the shape of the adhesive 4 is completely consistent with the cavity shape of the glue injection seam 3; wherein, the adhesive 4 forms a first convex block portion 41 corresponding to the first groove 111 of the pressing groove 11, and the adhesive 4 forms a second convex block portion 42 corresponding to the second groove 211 of the flange 21, the adhesive 4 and the basin frame 1 are mutually engaged through the first convex block portion 41 and the first groove 111, and the adhesive 4 and the yoke 2 are mutually engaged through the second convex block portion 42 and the second groove 211.

[0037] The first groove 111 and the second groove 211 of the present application not only increase the bonding area between the adhesive 4 and the basin frame 1 and the yoke 2, and improve the bonding force of the adhesive 4 to the basin frame 1 and the yoke 2, but also make the adhesive 4 interlock with the basin frame 1 and the yoke 2 respectively. Even if the speaker is subjected to a falling impact, due to the mutual restriction of the first protrusion portion 41 and the first groove 111, the second protrusion portion 42 and the second groove 211, the adhesive 4 is not easy to fall off from the glue injection groove 113, thereby reducing the risk of separation of the basin frame 1 and the yoke 2 when falling.

[0038] From the above description, it can be seen that the beneficial effect of the utility model is that: the speaker described in the utility model, the first protrusion portion 41 of the adhesive 4 is arranged in the first groove 111 of the basin frame 1, and the second protrusion portion 42 of the adhesive 4 is arranged in the second groove 211 of the yoke 2, which increases the bonding area between the adhesive 4 and the basin frame 1 and the yoke 2, improves the bonding force of the adhesive 4 to the basin frame 1 and the yoke 2, and the adhesive 4 forms a snap-fitting structure with the basin frame 1 and the yoke 2 respectively. When the speaker encounters a drop impact, the structure of the adhesive 4 is snap-fitted with the structure of the basin frame 1 and the structure of the yoke 2 respectively, so that the adhesive 4 will not fall off from the glue injection seam 3, and the basin frame 1 and the yoke 2 will not be separated, and the speaker has better anti-drop ability.

[0039] Furthermore, a first buckling surface 112 is provided on a side of the first groove 111 close to the bottom of the basin frame 1 , and a second buckling surface 212 is provided on a side of the second groove 211 close to the top of the flange 21 .

[0040] From the above description, it can be seen that the first snap-fitting surface 112 can be snapped with the bottom of the first protrusion portion 41. When the top of the speaker is subjected to a collision impact, the speaker is subjected to an impact force from its top toward its bottom. At this time, the first snap-fitting surface 112 conflicts with the bottom of the first protrusion portion 41 of the adhesive 4, and the adhesive 4 cannot move toward the bottom of the speaker under the action of the impact force; correspondingly, the second snap-fitting surface 212 can be snapped with the top of the second protrusion. When the bottom of the speaker is subjected to a collision impact, the speaker is subjected to an impact force from its bottom toward its top. At this time, the second snap-fitting surface 212 conflicts with the top of the second protrusion portion 42 of the adhesive 4, and the adhesive 4 cannot move toward the top of the speaker under the action of the impact force.

[0041] Furthermore, an inclined surface 213 is provided on the outer wall of the flange 21 near the top thereof.

[0042] From the above description, it can be seen that the inclined surface 213 not only makes it easier to install the basin frame 1 and the yoke 2, but also allows the adhesive 4 to form a corresponding structure corresponding to the inclined surface 213, so as to improve the stability of the fit between the structure of the adhesive 4 and the structure of the yoke 2, thereby further improving the anti-drop performance of the speaker.

[0043] Furthermore, a glue injection groove 113 is further provided on the pressing groove 11 near the bottom of the basin frame 1 , and the adhesive member 4 forms a third protrusion portion 43 corresponding to the glue injection groove 113 .

[0044] It can be seen from the above description that providing the glue injection groove 113 can facilitate glue injection.

[0045] In some preferred embodiments of the present invention, Figure 3 As shown, a groove structure may be formed between the first protruding block portion 41 and the second protruding block portion 42 , so that the buckling structure between the adhesive member 4 and the basin frame 1 is more stable.

[0046] Furthermore, a third buckling surface 114 is provided on a side of the glue injection groove 113 away from the bottom of the basin frame 1 .

[0047] Furthermore, the pressed groove 11 is a through groove that penetrates along the thickness direction of the basin frame 1 .

[0048] It can be seen from the above description that the pressed groove 11 is set as a through groove structure, which can more easily increase the bonding area between the adhesive 4 and the basin frame 1, thereby improving the bonding force between the adhesive 4 and the basin frame 1.

[0049] Furthermore, the pressing groove 11 is provided with a plurality of first grooves 111 arranged at intervals, a first spacing portion 115 is formed between two adjacent first grooves 111 , and the adhesive 4 forms a first spacing groove corresponding to the first spacing portion 115 .

[0050] Furthermore, the flange 21 is provided with a plurality of second grooves 211 arranged at intervals, a second spacing portion 214 is formed between two adjacent second grooves 211 , and the adhesive 4 forms a second spacing groove corresponding to the second spacing portion 214 .

[0051] From the above description, it can be seen that the first spacer 115 and the first spacer groove, and the second spacer 214 and the second spacer groove cooperate with each other, which can prevent the adhesive 4 from moving along the length direction or width direction of the speaker, thereby improving the reliability of the anti-falling structure between the speaker basin frame 1 and the yoke 2, and improving the speaker's anti-falling ability.

[0052] Furthermore, the first groove 111 and the second groove 211 are arranged opposite to each other.

[0053] Of course, in some preferred embodiments of the present application, the first groove 111 and the second groove 211 may also be staggered.

[0054] Furthermore, a first fixing portion 12 is provided on the inner wall of the basin frame 1 , and a second fixing portion 22 is provided on the outer wall of the flange 21 corresponding to the first fixing portion 12 .

[0055] It can be known from the above description that the first fixing portion 12 can be interference fit with the second fixing portion 22 .
