[0035] Example 1

[0036] Please refer to Figure 1 , Figure 2 and Figure 3As shown, this embodiment provides a speaker frame structure, including a frame 10, a top shell 20, and a bottom shell 30. The frame 10 has a hollow through hole 101 along one end face. The frame 10 has symmetrically arranged protrusions 102 extending into the hollow through hole 101 on the middle of the opposite side frames. The frame 10 has a plurality of limiting grooves 103 on the other end face of the hollow through hole 101. The other opposite side frames of the frame 10 have symmetrically arranged circuit board grooves 104 communicating with the end face. The top shell 20 is fitted onto one end face of the frame 10. The bottom shell 30 is fitted onto the other end face of the frame 10. The bottom shell 30 has a locking block 301 that engages with the limiting groove 103 and a folded edge 302 that abuts against the protrusion 102. The bottom shell 30 has a notch 303 that avoids the circuit board groove 104.

[0037] Specifically, the top shell 20 can be installed on one end face of the frame 10 by adhesive or snap-fit, making assembly or disassembly convenient during production or use, facilitating production, maintenance, and use. The bottom shell 30 is directly snapped onto the frame 10 through the abutting engagement between the protrusion 102 and the folded edge 302, and the snap-fit ​​between the limiting groove 103 and the locking block 301. Thus, the assembly of the bottom shell 30 and the frame 10, as well as the top shell 20 and the frame 10, is simple and convenient, enabling quick assembly and disassembly.

[0038] Furthermore, circuit board slots 104 are exposed at both ends of the frame 10. After the speaker is assembled, the conductive part of the circuit board or the conductive copper sheet on the circuit board slot 104 will be exposed. Therefore, the speaker can be directly plugged in to complete the connection and also achieve the effect of electrical connection, thus improving the convenience of use.

[0039] like Figure 2 and Figure 4 As shown, in this embodiment, the edge of the top shell 20 is provided with multiple first insertion portions 201, and the end face of the frame 10 located in the hollow through hole 101 is provided with a second insertion portion 105 that engages with the first insertion portions 201. For example, the first insertion portion 201 of the top shell 20 is a slot, while the second insertion portion 105 is a protrusion. Furthermore, four second insertion portions 105 are provided at the four corners of the frame 10. In this way, the four corners can be positioned by the four protrusions, forming a limiting positioning effect. Furthermore, the top shell 20 can also be glued together to ensure the stability of the assembly.

[0040] like Figure 1 and Figure 4As shown, in this embodiment, at least one insertion slot 106 is provided on the outer surface of the protrusion 102 of the frame 10. The top surface of the insertion slot 106 and the outer surface of the frame 10 are open. The insertion slot 106 is open on both sides, and multiple insertion slots 106 are symmetrically designed on both sides of the frame 10. In this way, after insertion, a symmetrical clamping and limiting effect can be formed to achieve the purpose of insertion and docking.

[0041] like Figure 1 As shown, in this embodiment, an adhesive groove 1041 is provided on the bottom end of the circuit board groove 104. The adhesive groove 1041 can be used to bond or solder circuit boards, conductive copper sheets, or conductive wires. The adhesive groove 1041 accommodates adhesive, thus preventing adhesive overflow during bonding. At the same time, the adhesive groove 1041 can also form a welding position for soldering, avoiding the solder joint protrusion and improving the flatness of the structure.

[0042] like Figure 1 As shown, in this embodiment, a connecting slot 107 is provided on the side wall between the circuit board slot 104 and the hollow through hole 101, and the bottom of the connecting slot 107 is flush with the bottom of the circuit board slot 104. The connecting slot 107 is connected to the hollow through hole 101 of the frame 10 so that the circuit board or conductive sheet can be led out from the frame 10 to the circuit board slot 104. At the same time, the flat design can ensure the flatness of the structure installation.

[0043] like Figure 1 and Figure 4 As shown, in this embodiment, a cutting groove 108 extending to the circuit board groove 104 is provided on the end face of the frame 10. The design of the cutting groove 108 makes it convenient to cut off the excess part of the circuit board during the assembly of the circuit board, so as to avoid the circuit board from extending out of the frame 10 and form an aligned cutting effect without the need for subsequent correction.

[0044] like Figure 1 As shown, in this embodiment, the frame 10 is provided with a plurality of positioning shallow grooves 109 on the other end face of the hollow through hole 101. The positioning shallow grooves 109 are designed so that when the speaker is plugged into the frame 10, the positioning shallow grooves 109 can form adhesive points and / or limiting points, so as to quickly fix the speaker.

[0045] Example 2

[0046] like Figure 4 As shown, this embodiment provides a loudspeaker, including the loudspeaker frame structure as described in Embodiment 1. This allows for quick plug-in installation of the loudspeaker, and after plugging in, the circuit board can make contact with an external power source, achieving the effect of quick installation and power connection.

[0047] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
