Abstract: A wireless earphone with radar capabilities includes a first earphone having a first detection unit and a container. When the first earphone is placed inside the container, a first detection wave generated by the first detection unit passes through the container. The first detection wave is reflected from a human body as a first reflected wave, and when the first detection unit receives the first reflected wave through the container, the first detection unit generates a first detection result data and sends the first detection result data to an external device. The container containing the first earphone allows a user to hold the container with the first earphone within, and since the first earphone continues to detect movements outside of the container, the container is transformed into a multifunctional controller or detector for adapting to new application modes initiated by the external device.

The driving module is used for producing a first driving voltage and a second driving voltage. The oscillating module comprises a first symmetric load circuit, a second symmetric load circuit, and a bias circuit.
