Abstract

The invention discloses a wireless earphone using a short-tail helical antenna and a short-circuited L-shaped radiator. The wireless earphone comprises a circuit board, a battery, a loudspeaker, a housing, a switch button and an antenna system. The antenna system comprises the short-tail helical antenna and the short-circuited L-shaped radiator. The short-circuited L-shaped radiator is an L-shaped structure. An input point is arranged on a circuit board. The short-tail helical antenna is connected with the input point in a spiral structure and the short-circuited L-shaped radiator is also connected with the input point. The input point is connected with a wireless module through a transmission line. The wireless earphone is provided with the short-tail helical antenna and the short-circuited L-shaped radiator in an orthogonal structure so that a diversity effect can be formed and can reduce the number of zero points of the antenna to greatly enhance the antenna receiving capability of the wireless earphone. In addition, the inductive effect of the short-circuited L-shaped radiator and the capacitive effect of the short-tail helical antenna form a resonant structure to increase the bandwidth of the antenna system, thereby improving the signal receiving performance and the acoustic effect of the earphone.
