[0029] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the accompanying drawings, a preferred embodiment of the present utility model is described in detail.

[0030] The present utility model embodiment provides a Bluetooth headset 1000, such as Figures 1 to 4 As shown, the Bluetooth headset 1000 includes a shell 100, which includes a front shell 110 and a rear cover 120. The rear cover 120 is installed on the back of the front shell 110 to define a accommodating cavity 130 together with the front shell 110. The rear cover 120 includes a first outer edge 121, which is arranged at the outer edge of the rear cover 120 close to the front shell 110. The front shell 110 includes a second outer edge 111 adjacent to the first outer edge 121. The rear cover 120 is fused to the front shell 110 to make the transition between the first outer edge 121 and the second outer edge 111 smooth; wherein, the front shell 110 is made of a material different from that of the rear cover 120, and the melting point of the front shell 110 is higher than that of the rear cover 120. The Bluetooth headset 1000 simplifies the connection method between the front shell 110 and the rear cover 120, thereby reducing the difficulty of processing and effectively avoiding the step problem at the connection point of the shell 100, providing a better user experience.

[0031] Specifically, the melting point of the front shell 110 is higher than that of the rear cover 120. The rear cover 120 is connected to the front shell 110 by melting, which is firm and less difficult to process than the traditional embodiment in which the front shell is snap-connected to the rear shell. In addition, since the rear cover 120 is softer in the molten state, the transition between the first outer edge 121 and the second outer edge can be smoother during the edge sealing process, that is, the connection between the rear cover 120 and the front shell can form a complete continuous outer surface, thereby preventing the outer shell 100 from having a step difference problem, thereby improving the overall user experience.

[0032] It should be noted that, when the existing front shell is snap-connected to the rear shell, in order to ensure the airtightness of the sound cavity, the two are glued before they are closed. However, when the glue is applied unevenly, it is easy to cause air leakage in the sound cavity. After implementing this solution, the rear cover 120 is directly connected to the front shell 110 by melting, which can improve the overall sealing and prevent air leakage.

[0033] Reference Figures 2 to 4 In one embodiment, the Bluetooth headset 1000 further includes a circuit board 200, the circuit board 200 is located in the accommodating cavity 130, and the circuit board 200 is at least partially embedded in the side of the rear cover 120 facing the accommodating cavity 130. The circuit board 200 is directly embedded in the rear cover 120, which simplifies the overall structure of the housing 100, reduces the number of additional connectors for fixing the circuit board 200, and makes the assembly process easier.

[0034] It is worth mentioning that, by implementing the above embodiment, because the circuit board 200 is directly embedded in the rear cover 120, the assembly gap is smaller, which can more effectively improve the space utilization of the accommodating cavity 130, making the internal structure of the entire Bluetooth headset 1000 more compact.

[0035] In one embodiment, the rear cover plate 120 is made of resin. The resin material has good processing performance and is easy to form and process. The rear cover plate 120 made of resin can not only be connected to the front shell 110 by hot melting, but also reduce the weight of the overall product, reduce the burden on users, and improve wearing comfort.

[0036] Furthermore, the front housing 110 is made of plastic. The front housing 110 made of plastic has good processability and is more conducive to manufacturing. At the same time, the plastic has certain flexibility and elasticity, which not only makes the user feel more comfortable when touching the front housing 110, but also improves the anti-fall performance of the housing 100.

[0037] Reference Figure 3In one embodiment, the rear cover 120 has a curved surface 122 at the adjacent position of the front housing 110. In this way, the curved surface 122 not only allows the user to take the device more naturally, reduces hand discomfort, and improves overall comfort, but also increases the overall aesthetics of the housing 100.

[0038] Reference Figure 2 and Figure 3 In one embodiment, the front housing 110 is provided with a mounting groove 112, and the rear cover 120 is fused and connected to the notch of the mounting groove 112, so that the rear cover 120 and the mounting groove 112 form a receiving cavity 130, and a supporting platform 1121a is provided on the peripheral wall 1121 of the mounting groove 112, and the circuit board 200 is sandwiched between the rear cover 120 and the supporting platform 1121a. The supporting platform 1121a provides a supporting surface for the circuit board 200, and limits the circuit board 200, so that when the rear cover 120 is hot-melted, the embedded position of the circuit board 200 is not easily displaced, thereby ensuring the effect of embedded connection.

[0039] Specifically, a plurality of support platforms 1121 a may be provided to increase the supporting points with the circuit board 200 , so that the circuit board 200 is placed more stably on the support platforms 1121 a .

[0040] Furthermore, the outer contour of the circuit board 200 is adapted to the peripheral wall 1121. This arrangement can prevent the circuit board 200 from lateral movement in the front housing 110, further limit the position of the circuit board 200, and improve the effect of the embedded connection between the circuit board 200 and the rear cover 120.

[0041] Reference Figure 5 and Figure 6 In one embodiment, the front housing 110 includes a front cover 113 and a hollow shell 114. The front cover 113 is disposed on one side of the hollow shell 114, the rear cover plate 120 is fused and connected to the other side of the hollow shell 114, and the support platform 1121a is disposed in the hollow shell 114. Dividing the front housing 110 into the front cover 113 and the hollow shell 114 makes it easier to install other components such as the dynamic assembly; specifically, the front cover 113 is detachably connected to the hollow shell 114.

[0042] More specifically, one of the male buckle 1131 or the female buckle 1141 is provided on the front cover 113 , and the other of the male buckle 1131 or the female buckle 1141 is provided on the hollow shell 114 . The male buckle 1131 cooperates with the female buckle 1141 to connect the front cover 113 to the hollow shell 114 .

[0043] There are many ways to set the male buckle 1131 and the female buckle 1141. For example, in this embodiment, the male buckle 1131 is a limiting boss, and the female buckle 1141 is a limiting groove, and the limiting boss is accommodated in the limiting groove to achieve limiting fixation.

[0044] Further, refer again to Figure 5 and Figure 6 The front cover 113 is provided with a groove 1132 on one side facing the hollow shell 114, and the hollow shell 114 is provided with a flange 1142 on one side facing the front cover 113. The flange 1142 is accommodated in the groove 1132. The flange 1142 includes a peripheral surface 1142a facing the side groove wall 1132a of the groove 1132. The peripheral surface 1142a is provided with a female buckle 1141. The male buckle 1131 is provided on the side groove wall 1132a. The groove 1132 is circular, so that the flange 1142 can rotate relative to the groove 1132, thereby making the male buckle 1131 and the female buckle 1141 engage or separate. The groove 1132 and the flange 1142 can realize the initial assembly positioning of the front cover 113 and the hollow shell 114, ensuring that they are correctly aligned during the assembly process, thereby making the male buckle 1131 and the female buckle 1141 more quickly fit. At the same time, the groove 1132 is set to be circular so that the flange 1142 can rotate relative to the groove 1132. By rotating the front cover 113, the male buckle 1131 and the female buckle 1141 can be engaged or separated, which is easier to operate and greatly improves the convenience of assembly.

[0045] Specifically, multiple male buckles 1131 and multiple female buckles 1141 can be provided, and the multiple male buckles 1131 are staggered along the circumference of the groove 1132, and the multiple female buckles 1141 are all arranged on the rotation path of the multiple male buckles 1131. The multiple male buckles 1131 and the multiple female buckles 1141 cooperate with each other to make the connection more secure.

[0046] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present utility model rather than to limit it. For those skilled in the art, the technical solutions described in the above embodiments can be modified, or some of the technical features therein can be replaced by equivalents; and all these modifications and replacements should fall within the scope of protection of the claims attached to the present utility model.
