Among them, due to the softness and regularity of the transfer flexible circuit board 4 and the first flexible circuit board 5, the convenience and regularity of the wiring can be guaranteed without winding. At the same time, it is not easy to generate unnecessary electrical signal noise or interference (bottom noise) in the circuit, so the signal transmission quality is guaranteed, the earphone works stably, and the user experience is improved. In this solution, the first wire 6 is only used as the transfer 4 connecting wire between the positive electrode 21 and the transfer flexible circuit board 4. Its length is not long, and it only needs to be led from the positive electrode 21 to the transfer flexible circuit board 4, so it will not cause messy wiring.

[0029] Specifically, Figure 1 As shown, the housing 1 is formed with an in-ear portion 11 and an outer rod portion 12, the main control circuit board 3 can be installed in the outer rod portion 12, and the battery 2, the main control circuit board 3, the transfer flexible circuit board 4, the first flexible circuit board 5 and the first wire 6 are all installed in the in-ear portion 11. When the earphone is in use, the in-ear portion 11 is worn in the ear canal, and the outer rod portion 12 is exposed outside the ear. The transfer flexible circuit board 4 and the first flexible circuit board 5 are both flexible printed circuit boards (Flexible Printed Circuit, FPC), which is a soft and thin circuit board used to connect various components in electronic devices. Due to its flexibility, the flexible circuit board can adapt to spaces of different shapes and curves, making its wiring in electronic devices more flexible and efficient. The arrangement of the first flexible circuit board 5 and the first wire 6 can make it easier for the positive electrode 21 and the negative electrode 22 of the battery 2 to be connected to the transfer flexible circuit board 4. The earphone of the utility model can be an ANC (Active Noise Cancellation) active noise reduction Bluetooth earphone.

[0030] Specifically, in one embodiment, the positive electrode 21 is electrically connected to the positive terminal of the transfer flexible circuit board 4 through the first flexible circuit board 5, and the negative electrode 22 is electrically connected to the negative terminal of the transfer flexible circuit board 4 through the first wire 6. In another embodiment, the positive electrode 21 is electrically connected to the positive terminal of the transfer flexible circuit board 4 through the first wire 6, and the negative electrode 22 is electrically connected to the negative terminal of the transfer flexible circuit board 4 through the first flexible circuit board 5.

[0031] Furthermore, if Figures 4 to 6 As shown, an inner bracket 7 is provided in the shell 1, and the battery 2 is installed on the inner bracket 7.

By setting the transfer circuit board 8, the first flexible circuit board 5, the first wire 6 and the transfer flexible circuit board 4 are electrically connected. By installing the transfer circuit board 8 on the top of the battery 2, the battery 2 can be used as the installation position of the transfer circuit board 8 to simplify the structure. The positive electrode 21 and the negative electrode 22 are arranged on the side of the battery 2. When the transfer circuit board 8 has been installed on the top of the battery 2, the remaining position of the battery 2 can be used to reasonably arrange its positive electrode 21 and negative electrode 22. The positive electrode 21 and the negative electrode 22 can be nickel sheets. The positive electrode 21 and the negative electrode 22 are wrapped with an insulating film 10.

[0033] The earphone also includes an insulating inner sleeve 9, which is sleeved on the side of the battery 2. The provision of the insulating inner sleeve 9 can effectively isolate the battery 2 from the external environment and provide additional safety protection. This helps to reduce the risk of short circuit between the battery 2 and other components, thereby reducing potential safety hazards and achieving insulation and protection of the battery 2 body. The insulating inner sleeve 9 can be made of silicone, rubber, plastic, etc. Further, the earphone also includes an insulating outer jacket, which is padded at the bottom of the battery 2 and covers the first flexible circuit board 5.

By arranging the noise reduction microphone 40 near the sound outlet in the housing 1, the noise in the environment can be effectively captured, and the noise can be reduced by the corresponding audio noise reduction technology, thereby improving the audio quality and user experience. The noise reduction microphone 40 is electrically connected to the main control circuit board 3 through the second flexible circuit board 50, the adapter circuit board 8, and the adapter flexible circuit board 4, which can greatly maintain the regularity and convenience of the wiring inside the earphone. The second flexible circuit board 50 is a flexible printed circuit board (Flexible Printed Circuit, FPC). The noise reduction microphone 40 is a type of microphone that can specifically capture and offset environmental noise. This type of microphone is designed to reduce the noise and noise of the surrounding environment during recording or calling, thereby providing clearer and purer sound. The noise reduction microphone 40 usually uses a variety of technologies to achieve noise reduction effects, including active noise reduction and passive noise reduction. Active noise reduction uses the built-in electronic components of the microphone to identify and counteract environmental noise. Passive noise reduction relies on the physical design of the microphone to isolate external noise. These technologies combined enable the noise reduction microphone 40 to provide clear audio input in a variety of environments. The design and application of the noise reduction microphone 40 can adopt existing technologies and will not be repeated here.
