[0028] The technical solutions in the embodiments of this utility model will now be clearly and completely described in conjunction with the accompanying drawings.

[0029] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the attached figure). If the specific posture changes, the directional indication will also change accordingly. Furthermore, descriptions involving "preferred," "second-best," etc., in this utility model are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined as "preferred" or "second-best" may explicitly or implicitly include at least one of those features.

[0030] Example 1 Figure 1As shown, an earphone device with an extended microphone connection includes an earphone 1 and an external microphone 2. The external microphone 2 is connected to an electrical connector 4 via a wire 3. In this case, there are two earphones 1, and the electrical connector 4 connected to the external microphone 2 is connected to one of the earphones 1. During installation, the external microphone 2 can be placed inside the helmet near the mouth.

[0031] like Figure 1-4 As shown, the earphone 1 contains an earphone magnetic attachment 5 and a PCB board 6. The PCB board 6 has a Bluetooth main control module that can wirelessly connect with smart devices. The electrical connector 4 has a connector magnetic attachment 7 corresponding to the earphone magnetic attachment 5, which connects the electrical connector 4 to the earphone 1. The earphone 1 has a conductive sheet 8 and an earphone speaker 9 that are electrically connected to the PCB board 6. The electrical connector 4 has a conductive part 10 that is electrically connected to the conductive sheet 8, enabling the external microphone 2 to communicate with the Bluetooth main control module. When the electrical connector 4 is connected to the earphone 1, the connector magnetic attachment 7 on the electrical connector 4 engages with the earphone magnetic attachment 5 inside the earphone 1, fixing the electrical connector 4 to the earphone 1. This causes the conductive sheet 8 on the earphone 1 to contact and connect with the conductive part 19 on the electrical connector 4, allowing the external microphone 2 to communicate with the Bluetooth main control module through the wire 3 and the electrical connector 4, thus transmitting the voice information received by the external microphone 2 to the Bluetooth main control module. When in use, the Bluetooth master control module on the earphone 1 establishes a Bluetooth communication connection with smart devices such as mobile phones, sending the music or call audio information from the smart device to the Bluetooth master control module, which then plays it through the earphone speaker 9. At the same time, the Bluetooth master control module sends the received voice information to the smart device, thus achieving wireless communication.

[0032] like Figure 2-3 As shown, the earphone 1 includes an earphone body 101 and an earphone speaker portion 102 connected to the earphone body 101. An earphone magnetic component 5, a PCB board 6, a conductive sheet 8, a rechargeable battery 12, and a Hall sensor 13 are disposed within the earphone body 101, and the earphone speaker 9 is disposed within the earphone speaker portion 102. The earphone body 101 has an earphone positioning groove 103 for inserting a power supply connector 4. The earphone magnetic component 5, the conductive sheet 8, and the Hall sensor 13 are disposed within the earphone positioning groove 103. The earphone positioning groove 103 enables quick positioning and connection between the power supply connector 4 and the earphone 1, and improves the tightness of the connection between the earphone 1 and the power supply connector 4.

[0033] In this case, the earphone magnetic 5 and the connector magnetic 7 are opposite magnets, which make the earphone 1 and the electrical connection connector 4 tightly connected; the conductive sheet 8 is a copper sheet, and the conductive part 10 is a conductive connection spring or spring, which makes the earphone 1 and the electrical connection connector 4 make better contact to achieve electrical connection.

[0034] like Figure 3As shown, the electrical connector 4 is equipped with a state-switching magnetic clasp 11. The earphone 1 contains a rechargeable battery 12 for supplying power to the PCB board 6. The PCB board 6 is equipped with a Hall sensor 13 connected to the Bluetooth main control module, which detects when the state-switching magnetic clasp 11 is close and switches between communication connection between the Bluetooth main control module and the external microphone 2 or charging of the rechargeable battery 12. The electrical connector 4 is connected to the earphone 1, and the state-switching magnetic clasp 11 and the Hall sensor 13 are positioned opposite each other. After the electrical connector 4 is connected to the earphone 1, the state-switching magnetic clasp 11 on the electrical connector 4 triggers the Hall sensor 13 on the earphone 1, causing the Hall sensor 13 to generate a detection signal. After the Bluetooth main control module receives the detection signal sent by the Hall sensor 13, it switches to the communication connection state with the external microphone 2 and receives the voice received by the external microphone 2. In this case, a charging cable assembly or a charging case is also provided. Both the charging cable assembly and the charging case are equipped with charging pins connected to the conductive sheet 8, and a charging magnetic clasp that cooperates with the earphone magnetic clasp. After the conductive piece 8 of the earphone 1 is connected to the charging pin, the Hall sensor 13 is not triggered, and the Bluetooth main control module switches to charging state for the rechargeable battery 12.

[0035] like Figure 4-5 As shown, the external microphone 2 includes a base shell 201, a microphone module 202, and a microphone metal mesh 203. The base shell 201 has a recess 204, the microphone module 202 is disposed within the recess 204, and a windproof sponge 205 covers the outside of the microphone module 202. The microphone metal mesh 203 covers the recess 204. By wrapping the microphone module 202 with the windproof sponge 205 and providing the microphone metal mesh 203 on the front of the microphone module 202, the voice quality for calls while riding is improved, and wind noise is reduced.

[0036] like Figure 1 and Figure 4 As shown, the upper bottom surface of the external microphone 2 is provided with a fixing component 14 for fixing the external microphone 2; the fixing component 14 includes Velcro or double-sided tape connected to the upper bottom surface of the external microphone, which facilitates quick fixing of the external microphone 2 to the helmet. In this case, the external microphone 2 is located at the center of the helmet brim or on the inner side of the lower lip of the full-face helmet.

[0037] like Figure 6 As shown, external microphone 2 can be used independently in this case; as Figure 7 As shown, this invention can also simultaneously utilize the built-in microphone in the earphone 1 and the external microphone 2. After connecting the external microphone 2, this invention will prioritize receiving the voice information received by the external microphone 2.

[0038] In this case, the external structure of the earphone 1 can also be as follows: Figure 8-9 The second embodiment shown and as shown Figure 10-11As shown in Embodiment 3, the appropriate shape and structure of the earphone 1 can be selected according to the user's preference.

[0039] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
