Structural features and design philosophy of the new Bluetooth phone case. So, what is a Bluetooth phone case? Simply put, it provides a space for Bluetooth integration within the case, combining it with the phone case to achieve diversified functionality.

A multi-functional smartphone case, including a shell with an interior cavity. The shell features openings for a camera and buttons, and a chamber on the rear side with an embedded slot. The slot has an adjustable stopper at its opening, and houses Bluetooth technology. This innovative multi-functional smartphone case has a simple structure, allowing for easy embedding of Bluetooth in the rear chamber, facilitating portability and use. Additionally, a lighting device is installed on one side of the chamber, benefiting consumers by reducing the need to use the phone's flash as a light source, thereby significantly extending both the phone's and battery's lifespan.

Advantages of the proposal:

1. The product is battery-free, easy to carry, and free from charging concerns.

2. If the PCBA utilizes FPC flexible board design, the overall thickness is approximately 2.5mm, making it extremely thin and light.

3. The solution has optimized anti-collision measures to address conflicts with traditional NFC application scenarios.
