Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0025] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0026] This application discloses a wireless headset with an expansion module interface. (Refer to...) Figure 1 A wireless earphone with an expansion module interface includes an earphone speaker 1, an ear stem 2 inserted into the bottom rear side of the earphone speaker 1, a limiting component 3 disposed inside the top of the ear stem 2, a power supply component 4 disposed inside the bottom of the ear stem 2, and an expansion component 5 disposed inside the ear stem 2.

[0027] Reference Figures 2-4The limiting component 3 includes a telescopic rod 31 fixedly connected to the inside of the right side of the ear stem 2. A locking block 32 is fixedly connected to the right end of the telescopic rod 31. A pressure spring 33 is fixedly connected to the middle of the left end face of the locking block 32. A fixing rod 34 is fixedly connected to the inside of the right side of the ear stem 2. A winding rope 35 is fixedly connected to the left side of the locking block 32. An inner groove 36 is opened inside the right side of the ear stem 2. A knob 37 is rotatably connected inside the right side of the ear stem 2. The fixing rod 34 is located to the left of the locking block 32. The end of the winding rope 35 away from the locking block 32 passes through the fixing rod 34 and the inner groove 36 in sequence and is wound and connected to the surface of the knob 37. The knob 37 extends to the outside of the ear stem 2. The side of the knob 37 extending to the outside of the ear stem 2 is attached to the surface of the outer wall of the ear stem 2. A slot 38 is opened on the left side of the headphone speaker 1. The locking block 32 and the slot 38 are matched and engaged. The end of the pressure spring 33 away from the locking block 32 is fixedly connected to the inside of the ear stem 2.

[0028] Reference Figures 3-5 The power supply component 4 includes a fixing plate 41 fixedly connected to the bottom of the inner wall of the ear stem 2. A buffer spring 42 is fixedly connected to the bottom end of the fixing plate 41. A pressure block 43 is fixedly connected to the bottom end of the buffer spring 42. A battery 44 is disposed inside the bottom end of the ear stem 2. A spiral block 45 is threadedly connected to the bottom end of the ear stem 2. The bottom end of the pressure block 43 and the top end of the battery 44 are adapted to fit together. The top end of the spiral block 45 extends into the interior of the ear stem 2. The top end of the spiral block 45 and the bottom end of the battery 44 are adapted to fit together. A wire 46 is electrically connected to the top end of the battery 44.

[0029] Reference Figures 2-3 The expansion component 5 includes a mounting block 51 set inside the ear stem 2. The bottom of the mounting block 51 has grooves 52 on both the left and right sides. Support rods 53 are fixedly connected to the left and right sides of the inner wall of the ear stem 2. The top of the support rods 53 are fitted and snapped into the inside of the grooves 52. The end of the wire 46 away from the battery 44 passes through the pressure block 43 and the fixing plate 41 and is electrically connected to the bottom of the mounting block 51. The mounting block 51 is equipped with devices such as heart rate monitoring, voice assistant and motion detection.

[0030] Working principle: The operator can insert the placement block 51 from the top of the ear handle 2 downwards into the ear handle 2. At this time, the placement block 51 slides down until the top of the support rod 53 is engaged in the bottom groove 52. At this time, the position of the placement block 51 is limited. Then, the battery 44 is inserted into the ear handle 2 from bottom to top, so that the top of the battery 44 is attached to the bottom of the pressure block 43. At this time, the spiral block 45 can be rotated. During the rotation of the spiral block 45, its top extends into the ear handle 2. During the rotation of the spiral block 45, it will push the battery 44 upwards until the spiral block 45 can no longer rotate. At this time, the spiral block 45 and the pressure block 43 limit the battery 44 inside the ear handle 2.

[0031] The operator then presses the locking block 32 to compress the pressure spring 33. At this time, the locking block 32 is pressed into the ear stem 2. The operator then inserts the ear stem 2 into the bottom of the headphone speaker 1. At this time, the pressure spring 33 remains compressed. When the ear stem 2 is fully inserted into the headphone speaker 1, the ear stem 2 moves the locking block 32 to the position of the locking slot 38. Then, the locking block 32 moves away from the ear stem 2 under the action of the rebound force of the pressure spring 33. At this time, the rebound force of the pressure spring 33 will cause the locking block 32 to engage inside the locking slot 38. At this time, the position of the ear stem 2 is limited by the mutual limitation between the locking block 32 and the locking slot 38 and the mutual limitation between the ear stem 2 and the headphone speaker 1. At this time, the ear stem 2 is stably inserted into the bottom of the headphone speaker 1.

[0032] When it is necessary to disassemble the ear handle 2, the knob 37 can be turned to wind the winding rope 35. At this time, the winding rope 35 will pull the locking block 32 to compress the pressure spring 33, thereby causing the locking block 32 to disengage from the slot 38. Then the operator can forcefully pull out the ear handle 2 to disassemble the internal mounting block 51.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
