The power input terminal of the wireless charging circuit board is connected to the power output terminal of the wireless charging coil. The positive and negative terminals of the power output terminal of the wireless charging circuit board are respectively connected to the elastic contacts arranged in parallel on the earpiece. The turntable has a first electrode ring that contacts the elastic contacts. The turntable contains a power output circuit board, the power input terminal of which is connected to the first electrode ring, and the other end is exposed on the upper surface of the turntable.
[0009] The power output terminal of the power output circuit board is connected to LED beads and / or equipped with positive and negative terminals, which supply power to external auxiliary devices.
[0010] The connecting device for the smartphone lens accessory of this application, adopting the above structure, has the following advantages: 1. The magnetic base and the turntable are connected by a rotating column. By adjusting the relative rotation between the two, the additional lens or filter loaded on the turntable can be aligned with the mobile phone camera, thereby providing additional functions for the mobile phone lens. 2. The magnetic base contains a wireless charging coil and a wireless charging circuit board, which can wirelessly charge mobile phones and external devices. 4. The magnetic base can also be equipped with a rechargeable lithium battery and a charging circuit board module, which can charge the lithium battery or power external devices by connecting to a charger or the charging port of a mobile phone. 5. The side end of the ear plate seat is provided with a limiting protrusion, which on the one hand restricts the rotation direction of the turntable, and on the other hand ensures the overlapping position of the magnetic base and the turntable when not in use. 6. The circuit board inside the magnetic base earpiece is equipped with elastic contacts, which can transmit the power from the mobile phone to the turntable through the first electrode ring of the turntable to continuously power the turntable. 5. LED lights can be installed on the turntable as fill lights to provide supplemental lighting for the subject when the attached lens or other accessories block the phone's flash. 6. The turntable has one or more through holes or threads at its center or other locations for loading additional lenses or filters and other accessories. Attached Figure Description
