[0032] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0033] Please refer to Figures 1 to 7 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, which is an earphone charging case.

[0034] The charging slot 31 on the tray 30 is used to hold the earphone main unit 40; the contoured slot 120 on the main body 10 is used to hold the external microphone 50. The first magnet 12 holds the external microphone 50 in place, preventing it from falling out. This type of earphone charging case can simultaneously store the earphone main unit 40 and the external microphone 50, making it more versatile.

[0035] This application provides an earphone charging case, including a case body 10, a lid 20, and a tray 30. The tray 30 is disposed on the case body 10. The lid 20 is rotatably disposed on the tray 30 and can close onto the case body 10. The tray 30 is provided with a charging slot 31 for placing an earphone host 40. A circuit board 110 and a first magnet 12 are disposed inside the case body 10. A first charging pin 111 on the circuit board 110 is exposed in the charging slot 31, and the first charging pin 111 is in communication with a second charging pin 41 on the earphone host 40. A contoured groove 120 is provided on the outer wall of the case body 10. An external microphone 50 is embedded in the contoured groove 120 and is magnetically attracted to the first magnet 12. In this embodiment, the case body 10, lid 20, and tray 30 can be made of rigid plastic. In this embodiment, the lid 20 is hinged to the tray 30, and the tray 30 is fastened to the case body 10, so that the lid 20 can be flipped onto the case body 10. The charging slot 31 is used to house the headphone main unit 40. The first charging pin 111 on the circuit board 110 is connected to the second charging pin 41 on the headphone main unit 40, enabling charging of the headphone main unit 40. The contoured slot 120 is adapted to the structure of the external microphone 50. When the external microphone 50 is embedded in the contoured slot 120, the first magnet 12 of the main body 10 attracts the external microphone 50, thus fixing the external microphone 50 in the contoured slot 120 and preventing it from falling out. Therefore, this headphone charging case can simultaneously house the headphone main unit 40 and the external microphone 50, offering more comprehensive functionality. Furthermore, this design for housing the external microphone 50 also facilitates the miniaturization of the charging case, especially beneficial for the layout of ear-hook headphones, resulting in a compact structure and higher space utilization. In this embodiment, the external microphone 50 is magnetically attached to the headphone main unit 40; therefore, this charging case cleverly utilizes the structure of the external microphone 50 for its fixation, resulting in a more ingenious structure.

[0036] Preferably, the tray 30 has a fastening hole 32 on its side, and the box body 10 has a fastening block 13 on its inner wall; the tray 30 is fastened to the box body 10, and the fastening block 13 is embedded in the fastening hole 32. During assembly, pressing the tray 30 will fasten the tray 30 to the box body 10, and the fastening block 13 will be embedded in the fastening hole 32. The assembly structure between the tray 30 and the box body 10 is very simple, and the assembly is more convenient.

[0037] Preferably, the tray 30 is provided with a pivot 33 and a spring 34. The pivot seat 22 of the lid 20 is provided with a pivot hole 21, through which the pivot 33 passes. The pivot seat 22 can compress the spring 34. The first end of the spring 34 is inserted into the tray 30, and the second end of the spring 34 is inserted into the pivot seat 22. The pivot 33 passes through the pivot hole 21. When the lid 20 is flipped, the pivot seat 22 can compress or release the spring 34. The spring 34 provides elastic force to the lid 20, which requires external force to open. This design prevents the lid 20 from loosening. The box body 10 is provided with a clearance opening to avoid the pivot seat 22, so that the lid 20 can be flipped without interference.

[0038] Preferably, the left and right inner walls of the contoured groove 120 are provided with protrusions 121, which press against the microphone stem 52 of the external microphone 50. A notch 122 is provided at the end of the contoured groove 120, exposing the contoured shell 51 of the external microphone 50. When the external microphone 50 is embedded in the contoured groove 120, the protrusions 121 press against the microphone stem 52, and the contoured shell 51 is attracted by the first magnet 12. Therefore, the entire external microphone 50 is well fixed in place by the notch 122, preventing it from loosening or falling off. In use, the external microphone 50 can be easily removed by hand from the notch 122. Microphone components are housed inside the microphone stem 52.

[0039] Preferably, the box body 10 is made of rigid plastic, and the straw 52 is made of elastic plastic or elastic silicone. The box body 10 is made of one of the following materials: ABS, polyurethane (PU), polystyrene (PS), polyethylene (PE), and polymethyl methacrylate (PMMA). The straw 52 is elastic so that it can be firmly pressed by the protrusion 121.

[0040] Preferably, a battery 112 is also disposed inside the main body 10. The battery 112 is connected to the circuit board 110. The circuit board 110 is provided with an indicator light and a connector 117. The connector 117 is exposed on the back of the main body 10, and the indicator light is exposed on the front of the main body 10. A clearance hole for the battery 112 is provided in the middle of the circuit board 110; a battery slot 113 is provided on the inner wall of the main body 10; a cushioning pad 114 is attached to the battery 112; the battery 112 is disposed in the battery slot 113, and the tray presses on the cushioning pad 114. The battery 112 is preferably a lithium battery 112. The battery 112 is centered on the circuit board 110 for flexible layout. The indicator light is used to indicate the charging box shape. The connector 117 can be used for charging. The tray presses on the cushioning pad 114, which protects the battery 112 and restricts its position to prevent it from loosening. The cushioning pad 114 is preferably a sponge pad or a silicone pad.

[0041] Preferably, the inner wall of the housing body 10 is provided with a first groove 11, and the first magnet 12 is disposed in the first groove 11. The inner side of the tray 30 is provided with a second groove 115, and a second magnet 116 is disposed in the second groove 115. The second magnet 116 is magnetically attracted to the headphone host 40. The first magnet 12 can be glued to the first groove 11, and the second magnet 116 can be glued to the second groove 115. The headphone host 40 and the second magnet 116 can be magnetically attracted to each other, thus fixing the headphone host 40.

[0042] Preferably, the front of the tray 30 is provided with a recessed portion 35 for opening the lid 20. The lid 20 can be opened with fingers through the recessed portion 35, a design that is very convenient and improves overall aesthetics.

[0043] In summary, the key design feature of this utility model is that the charging slot 31 on the tray 30 is used to store the headphone main unit 40; the contoured slot 120 on the main body 10 is used to store the external microphone 50, and the first magnet 12 attracts the external microphone 50. This headphone charging case can store both the headphone main unit 40 and the external microphone 50, making it more comprehensive in function.
