[0029] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0030] In the description of the present invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of the present invention and simplify the description. They are not intended to indicate or imply that the devices or elements referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally located component.

[0031] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0032] like Figures 1 to 6 As shown, the embodiment of the present invention provides an easy-to-assemble Bluetooth headset housing structure, including a bottom shell 1, a face shell 2, a circuit board 3, a pressing plate 4, a limit card seat 5, a speaker cavity 6 and a speaker 7. The bottom shell 1 is provided with a accommodating chamber 10, and the circuit board 3 is arranged in the accommodating chamber 10. Positioning slots 11 are provided on both sides of the bottom shell 1, and a positioning insert 21 connected to the positioning slot 11 is provided on the face shell 2. The bottom shell 1 on both sides of the positioning slot 11 is provided with a press buckle 12, and the face shell 2 is provided with a pressure block 22 connected to the press buckle 12 by buckling; The provision of the positioning slot 11 and the positioning insert 21 facilitates the precise alignment of the face shell 2 and the bottom shell 1 during the assembly process, avoids misalignment or assembly errors, and improves assembly efficiency; the buckle 12 and the pressure block 22 are connected by buckling, which improves the stability of the assembly structure between the bottom shell 1 and the face shell 2, and the assembly method is relatively simple. It is only necessary to align the face shell 2 with the bottom shell 1 and apply a certain pressure to complete the buckling, which greatly simplifies the assembly process; at the same time, when disassembly is required, it is only necessary to unfasten the buckle 12 to easily separate the face shell 2 and the bottom shell 1, which is convenient for the maintenance and replacement of internal components.

[0033] The circuit board 3 is provided with a first button 31 on both sides of the end surface close to the face shell 2, and a pressing spring piece 23 is provided on the face shell 2. The bottom of the pressing spring piece 23 is provided with a positioning protrusion 231 that abuts against the first button 31. The positioning protrusion 231 is used to touch and abut against the first button 31 as the pressing spring piece 23 is squeezed. The pressing plate 4 is provided on the pressing spring piece 23, and anti-slip protrusions 41 are provided on both sides of the pressing plate 4 for easy pressing; when the user presses the pressing plate 4, the positioning protrusion 231 will accurately squeeze and touch the first button 31, thereby realizing the functional operation of the Bluetooth headset; the setting of the anti-slip protrusion 41 can enhance the user's feel and operating experience when pressing, and prevent fingers from slipping. It should also be noted that when the user applies pressing force, the pressing spring 23 can absorb part of the pressure and transfer it to the positioning protrusion 231, which then touches the first button 31. This process effectively disperses the pressure and prevents excessive force from directly acting on the circuit board 3 and causing pressure loss, thereby extending the service life of the earphones.

[0034] The limit holder 5 is provided at the end of the pressing spring piece 23, and the limit holder 5 abuts against the side wall of the pressing plate 4 to limit the pressing plate 4 from detaching from the pressing spring piece 23, thereby improving the stability of the pressing plate 4 in long-term use and preventing the pressing plate 4 from gradually loosening during repeated pressing.

[0035] The speaker cavity 6 is connected to the bottom shell 1 by a snap-fit connection, and the speaker 7 is disposed in the speaker cavity 6. The snap-fit connection allows the speaker cavity 6 to be quickly fixed to the bottom shell 1. Compared to traditional fixing methods such as screws and glue, the snap-fit connection is simpler and can significantly reduce assembly time and operation steps, thereby improving production efficiency.

[0036] like Figure 4 As shown, further, a battery 8 is included. The battery 8 is arranged in the accommodating chamber 10 and is electrically connected to the circuit board 3. The battery 8 is used to power the speaker 7.

[0037] like Figure 3 As shown, further, the pressing spring piece 23 is provided with a plurality of positioning holes 230, and the bottom of the pressing plate 4 is provided with a plurality of positioning columns 42 adapted to be connected with the positioning holes 230. Such a setting can avoid the pressing plate 4 from being offset or misaligned during the assembly process.

[0038] like Figure 2 and Figure 4As shown, further, a first press key 91 and a second press key 92 are included, and a second button 32 and a third button 33 are respectively provided on both sides of the circuit board 3. The first press key 91 and the second press key 92 are respectively provided on both sides of the bottom shell 1, and the first press key 91 abuts against the second button 32, and the second press key 92 abuts against the third button 33. Such a setting can facilitate the user to perform the pressing operation with the thumb or index finger, thereby improving the user's experience.

[0039] like Figure 1 As shown, further, a hollow portion 20 is provided on the surface shell 2 at the side end of the limit card seat 5. The setting of the hollow portion 20 can provide users with a more convenient key operation space, reduce the operation obstacles of fingers, and improve the accuracy and convenience of operation.

[0040] like Figure 5 and Figure 6 As shown, further, a limit card shaft 61 is provided on the speaker cavity 6, and a step hole 100 for the limit card shaft 61 to extend into is provided on the bottom shell 1, and a top block 611 is provided at the end of the limit card shaft 61 for engaging with the step hole 100. Such arrangement allows the limit card shaft 61 to be firmly fixed on the bottom shell 1 through the snap-fit action of the top block 611 after extending into the step hole 100, thereby preventing the limit card shaft 61 from accidentally slipping off the bottom shell 1.

[0041] like Figure 5 and Figure 6 As shown, further, a limit groove 101 is provided at the side end of the step hole 100, and a limit column 612 corresponding to the limit groove 101 is provided on the limit card shaft 61. The limit column 612 is used to limit the rotation of the limit card shaft 61 to avoid the position change of the speaker cavity 6 due to rotation, which affects the sound effect of the speaker 7.

[0042] like Figure 5 and Figure 6 As shown, the earphones further include an ear hook 62, which is connected to the limiting shaft 61 by a sleeve arrangement, and can rotate relative to the limiting shaft 61. The ear hook 62 can prevent the Bluetooth headset from slipping off the ear. The ear hook 62 can rotate relative to the limiting shaft 61, allowing the user to adjust the angle of the ear hook 62 according to their ear shape and wearing habits, thereby finding a comfortable and stable wearing position.
