[0039] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the utility model provides a speaker that is easy to assemble, comprising a speaker 1, a speaker pad 2 and a speaker shell 3, wherein the speaker pad 2 is fixedly arranged between the speaker 1 and the speaker shell 3, and the speaker shell 3 is provided with an opening 4, and the top of the speaker pad 2 is circumferentially provided with an edge portion 5 that is adapted to be positioned and installed with the opening 4, the opening 4 is provided with a groove 6, and a protrusion 7 that is engaged with the groove 6 is provided on the edge portion 5, and a mounting groove 9 for mounting the speaker 1 is provided at the bottom of the speaker pad 2, and an opening 10 for placing the speaker 1 is provided on the bottom surface of the mounting groove 9, and a mounting portion 11 for fixing the speaker 1 is provided on the periphery of the opening 10.

[0040] It can be understood that the speaker pad 2 can be positioned through the edge portion 5 and the opening 4 on the speaker shell 3 to ensure that the speaker pad 2 can be accurately installed on the speaker shell 3, the protrusion 7 on the edge portion 5 can be engaged with the groove 6 on the opening 4, and the protrusion 7 can prevent the speaker pad 2 from falling from the opening 4, and the protrusion 7 and the groove 6 are fixed by an adhesive, and the adhesive is glue. The mounting groove 9 is located at the bottom of the speaker pad 2, and the speaker 1 is installed on the mounting groove 9 at the bottom of the speaker pad 2, and the mesh cover 8 is installed and fixed to the speaker pad 2. Since the mounting groove 9 is a sunken design, when the speaker 1, the mesh cover 8 and the speaker pad 2 are fixed, a large distance is maintained between the speaker 1 and the mesh cover 8, and this distance can prevent the speaker 1 from hitting the mesh on the mesh cover 8 when working, thereby generating vibration sound.

[0041] Compared with the prior art, in the technical solution of the utility model, the sound installation groove 9 can increase the distance between the speaker 1 and the mesh cover 8 to prevent the speaker 1 from hitting the mesh cover 8 and thus generating vibration sound; the speaker pad 2 is integrally formed by a mold, which can save additional processing steps such as punching the speaker pad 2 before installation; and the speaker pad 2 and the speaker housing 3 are positioned and installed by the edge portion 5 and the opening 4, and the installation position accuracy is relatively high.

[0042] Furthermore, if Figure 3 As shown, the mounting portion 11 is provided with a fixing hole 23 , through which the sound box pad 2 and the sound box speaker 1 can be fixed.

[0043] Preferably, if Figure 4 As shown, a column 24 is provided at the bottom of the mounting portion 11, the axis of the column 24 is colinear with the axis of the fixing hole 23, and the fixing hole 23 runs through the column 24. It can be understood that the fixing between the speaker pad 2 and the speaker 1 is achieved by screwing in the fixing hole 23. Since the thickness of the speaker pad 2 is small, it is easy to cause the fixing between the screw and the speaker pad 2 to be relatively unstable. Therefore, the column can strengthen the installation stability between the screw and the speaker pad 2, that is, it can ensure that the installation between the speaker 1 and the speaker pad 2 is stable and reliable.

[0044] Furthermore, if Figure 4As shown, the mounting portion 11 is composed of a plurality of circumferentially arranged triangular protrusions 25. It should be noted that the triangular protrusions 25 can reduce the material used for the mounting portion 11, increase the net volume inside the speaker, and the triangular protrusions 25 can increase the strength of the mounting portion 11, so that the installation between the speaker pad 2 and the speaker 1 is more stable.

[0045] Furthermore, if Figure 5 As shown, the bottom surface of the mounting portion 11 is provided with a buckle 12 for snapping with the speaker housing 3. It should be noted that when the speaker 1 is placed for installation, the buckle 12 can prevent the speaker pad 2 from falling into the opening 4 of the speaker housing 3, that is, the buckle 12 can enhance the installation stability of the speaker pad 2 and the speaker housing 3.

[0046] Furthermore, if Figure 2 As shown, a glue groove 13 is provided between the protrusion 7 and the inner side wall of the groove 6. It can be understood that when the protrusion 7 and the bottom surface of the groove 6 are fixed by glue, the side surface of the protrusion 7 and the side surface of the groove 6 can be bonded and fixed by the glue groove 13, that is, the glue groove 13 can make the connection between the protrusion 7 and the groove 6 more stable.

[0047] It should be noted that since the contact area between the protrusion 7 and the groove 6 is small, it can prevent the speaker pad 2 and the speaker shell 3 from having too large a contact area to cause vibration, and the glue groove 13 can make the protrusion 7 and the groove 6 directly glued more fully, that is, it can prevent vibration caused by the glue not being fully applied.

[0048] Furthermore, the protrusion 7 is provided with an auxiliary reinforcement hole 15 which is compatible with the reinforcement fixing hole 14 on the speaker housing 3 , and the auxiliary reinforcement hole 15 can help the protrusion 7 to be more stably connected to the speaker housing 3 .

[0049] In one embodiment, if Figure 6 As shown, a boss 16 is provided at the bottom of the protrusion 7, the auxiliary reinforcement hole 15 is opened on the bottom surface of the boss 16, and the boss 16 is located in the reinforcement fixing hole 14. It can be understood that a screw is driven into the reinforcement fixing hole 14 on the bottom surface of the boss 16 to fix the protrusion 7 to the speaker housing 3.

[0050] In another embodiment, if Figure 7 As shown, the auxiliary reinforcement hole 15 is opened on the top surface of the protrusion 7, and the auxiliary reinforcement hole 15 is a countersunk hole, that is, the protrusion 7 and the speaker housing 3 can be fixed through the countersunk hole.

[0051] It should be noted that, on the basis of the protrusion 7 being adhesively fixed to the groove 6 on the speaker shell 3, the protrusion 7 is further fixed to the speaker shell 3 through the reinforced fixing hole 14 on the boss 16, that is, the protrusion 7 and the speaker shell 3 are doubly fixed, which can make the connection between the speaker pad 2 and the speaker shell 3 more stable.

[0052] Furthermore, if Figure 8 As shown, a mesh cover 8 is installed on the speaker pad 2, and a step 17 for installing the mesh cover 8 is provided inside the speaker pad 2, and the step 17 is located above the mounting groove 9, that is, the mesh cover 8 can be installed above the mounting groove 9 through the step 17, ensuring that a large distance is maintained between the mesh cover 8 and the speaker 1 on the mounting groove 9, so as to prevent the speaker 1 from hitting the speaker mesh cover 8 when working.

[0053] It should be noted that if Figure 5 As shown, for a speaker that needs to install the speaker 2 upside down, since the speaker 1 is at the bottom of the speaker housing 3, the mesh cover 8 is not needed to cover the speaker 1, that is, the step 17 does not need to be provided on the speaker pad 2.

[0054] Furthermore, if Fig. 9 and Fig.10 As shown, the mesh cover 8 includes an annular body 18 and a gauze arranged on the surface of the annular body 18. The annular body 18 is provided with a plurality of air holes 19 on its circumference. The air holes 19 enable the sound generated by the vibration of the speaker 1 to be smoothly transmitted from the mesh cover 8. Fig.10 and Fig.11 As shown, the cross-section of the annular body 18 is U-shaped or L-shaped. The inner side of the L-shaped annular body 18 is shorter, which is conducive to ventilation and can better transmit sound. The annular body 18 is provided with reinforcing ribs (not marked in the figure), and the reinforcing ribs can effectively improve the strength of the annular body 18 and increase the service life of the mesh cover 8.

[0055] Furthermore, if Fig.12 and Fig.13 As shown, the speaker provided in the present application also includes a speaker skin 20, and the speaker skin 20 covers the upper surface 21 of the speaker shell 3 and the speaker pad 2, or the speaker skin 20 covers the upper surface 21 of the speaker shell 3 and the speaker pad 2, and extends to cover the inner side 22 of the speaker pad 2.

[0056] It should be noted that the speaker patch can not only make the connection between the speaker pad 2 and the speaker shell 3 more stable, but also enable the speaker patch 20 to cover the protrusion 7 and the edge 5 when viewed from the surface of the speaker shell 3, thereby making the appearance of the speaker shell 3 more beautiful.

[0057] In summary, the utility model provides a speaker that is easy to assemble, the column base can strengthen the installation stability between the screw and the speaker pad, that is, it can ensure that the installation between the speaker speaker and the speaker pad is stable and reliable, the triangular protrusion can improve the strength of the installation part, the buckle can prevent the speaker pad from falling into the opening of the speaker shell, the glue groove can make the connection between the protrusion and the groove more stable, the auxiliary reinforcement hole can assist the connection between the protrusion and the speaker shell to be more stable, the cross-section of the annular body is U-shaped, which can effectively improve the annular body is strengthened, and improve the service life of the mesh cover, the speaker skin can cover the protrusion and the edge, so that the appearance of the speaker shell is more beautiful.
