Abstract: An improved band pass filter of π-type inductor is disclosed, which utilizes the serial inductor in the π as a compensating inductor, which can lower the coupling coefficient of the band pass by adjusting the inductance ratio of the compensating inductor to that of the two parallel grounded inductors. Therefore, the coupling coefficient is lowered by adjusting the inductance of the π-type inductors, avoid noise generation, and obtain optimal band pass characteristics, while miniaturizing the filter.

Abstract: A single-ear wireless headset is provided herein, which mainly contains a body member, an arm member, a hook member, and a joint member having a twisting element. On the two sides of the body member, two radially opposing connecting holes are provided for the connection to the joint member and the arm member respectively. The joint member in turn houses a leg of the L-shaped twisting element whose other leg is embedded inside the hook member. Because of the configuration of the twisting element, the hook member can be swung around the joint member for wearing on a user's either left or right ear, without altering the orientation of the ornament features on the body member and the hook member.
