[0044] The portable speaker of this embodiment includes:

[0045] Please also read Figure 4 and Figure 5 , a first half shell 1, a second half shell 2 docked with the first half shell 1, and a control board 3 arranged between the first half shell 1 and the second half shell 2; wherein the control board 3 is formed with a relative first fixing structure 31 and a second fixing structure 32, the inner shell wall of the first half shell 1 is provided with a first limiting structure 11 and a second limiting structure 12, a first limiting space matching the first fixing structure 31 is formed between the first limiting structure 11 and the second limiting structure 12, the inner shell wall of the second half shell 2 is provided with a third limiting structure 21, the third limiting structure 21 is provided with a second limiting space matching the second fixing structure 32, the first fixing structure 31 is inserted into the first limiting space and the second fixing structure 32 is inserted into the second limiting space, so that the control board 3 is fixed between the first half shell 1 and the second half shell 2.

[0046] Here, it can be understood that the first half shell 1 refers to a part of the housing of the portable speaker, the first half shell 1 refers to the outermost component of the portable speaker, and the first half shell 1 is used as a mounting base for the control board 3, and can also protect the control board 3; the second half shell 2 refers to another part of the housing of the portable speaker, the second half shell 2 refers to the outermost component of the portable speaker, and the second half shell 2 is used as a mounting base for the control board 3, and can also protect the control board 3;

[0047] The second half shell 2 is connected to the first half shell 1 to assemble into a shell. Here, the connection method between the second half shell 2 and the first half shell 1 includes but is not limited to screw connection, snap connection, adhesive connection, magnetic adsorption connection, or other connections that can connect and fix the two components.

[0048] The control board 3 refers to a component used to control the working state of the portable speaker. The control board 3 has the functions of receiving, processing and outputting information. The control board 3 is formed with a first fixed structure 31 and a second fixed structure 32, wherein the first fixed structure 31 and the second fixed structure 32 are located on opposite sides of the control board 3.

[0049] The inner shell wall of the first half shell 1 is provided with a first limiting structure 11 and a second limiting structure 12, wherein a first limiting space is formed between the first limiting structure 11 and the second limiting structure 12, and the shape and size of the first limiting space match the shape and size of the first fixing structure 31 of the control board 3, so that the first fixing structure 31 can be just inserted into the first limiting space and limited between the first limiting structure 11 and the second limiting structure 12;

[0050] The inner shell wall of the second half shell 2 is provided with a third limiting structure 21, and the third limiting structure 21 forms a second limiting space.

[0051] The assembly principle of the portable speaker provided in this embodiment is as follows:

[0052] The first fixing structure 31 of the control board 3 is inserted into the first limiting space, that is, the first fixing structure 31 is fixed relative to the first half shell 1 under the limitation of the first limiting structure 11 and the second limiting structure 12, and then the second half shell 2 is docked with the first half shell 1. At the same time, since the control board 3 is limited in the first limiting space, the control board 3 is fixed relative to the first half shell 1. Therefore, when the second half shell 2 is docked with the first half shell 1, the second fixing structure 32 of the control board 3 is inserted into the second limiting space of the second half shell 2, that is, the second fixing structure 32 is limited by the third limiting structure 21 and fixed relative to the second half shell 2. In this way, the first limiting structure 11 and the second limiting structure 12 on the opposite sides of the control board 3 are both fixed, so the control board 3 is fixed between the first half shell 1 and the second half shell 2.

[0053] By adopting the above technical solution:

[0054] First, the control board 3 can be fixed between the first half shell 1 and the second half shell 2 through the first limiting space and the second limiting space, thereby achieving the fixation of the control board 3. Compared with the prior art, the fixing method of the control board 3 of this embodiment does not require the aid of fasteners, and the fixing method of the control board 3 is simple to operate and convenient for assembling the control board 3.

[0055] Secondly, the control board 3 is fixed synchronously by the docking of the first half shell 1 and the second half shell 2, and the assembly efficiency is high;

[0056] Finally, the fixing method of the control panel 3 does not require fasteners, which saves the assembly cost of this part and reduces the manufacturing cost.

[0057] In addition, the above design can maximize the internal cavity volume of the portable speaker to meet acoustic requirements, and uses less shell material, which is convenient for assembly and saves costs. At the same time, the portable speaker has a curved surface and additional bone positions and buckles, which improves overall reliability.

[0066] Here, it can be understood that the shape of the first half shell 1 is a bowl-shaped structure, the first shell portion 13 is the bottom of the bowl-shaped structure, and the second shell portion 14 is the periphery of the bowl-shaped structure, wherein the protrusion is arranged on the first shell portion 13 and the convex strip is arranged on the second shell portion 14.

[0067] By adopting the above technical solution, the first half shell 1 is in a bowl shape, which is beneficial to the arrangement of the protrusions and the convex strips.

[0068] In one embodiment, the third limiting structure 21 is a convex rib arranged on the inner shell wall of the second half shell 2, and the convex rib is provided with a second limiting groove 211 for forming a second limiting space, and the notch of the second limiting groove 211 is arranged toward the first half shell 1.

[0070] By adopting the above technical solution, the second limiting groove 211 can form a second limiting space, and the notch of the second limiting groove 211 is arranged toward the first half shell 1, which is convenient for inserting the second fixing structure 32 of the control board 3.

[0071] In one embodiment, the second limiting groove 211 is provided with a guide slot 212 , and the guide slot 212 gradually shrinks along the groove depth direction.

[0072] Here, it can be understood that the guide groove 212 is used to guide the second fixed structure 32 of the control panel 3 to enter the second limiting groove 211; wherein, the guide groove 212 gradually shrinks along the groove depth direction. Since the second fixed structure 32 of the control panel 3 is inserted along the groove depth direction of the second limiting groove 211, the above design can make the second fixed structure 32 gradually enter the second limiting groove 211, thereby improving the assembly speed of the control panel 3 and avoiding the misalignment of the control panel 3 and the third limiting structure 21.

[0073] By adopting the above technical solution, the assembly speed of the control board 3 is increased and the risk of misalignment is reduced.
