Abstract

The invention discloses an earphone antenna and a connector thereof, and the earphone antenna comprises an audio signal line, an antenna and a radio frequency impedance component. The audio signal line is used to transmit audio signals, and the antenna is used to receive radio frequency signals, wherein, the radio frequency impedance component is configured on a path of audio signals. The radio frequency impedance component can produce rather large equivalent impedance on a frequency band of the radio frequency signals to make the audio signal line be equivalent to the disconnected state on the frequency band of the radio frequency signals, so as to improve the receiving effects of the radio frequency signals.

Description

technical field [0001] The present invention relates to a circuit structure design of an antenna circuit, and in particular relates to a circuit structure design of an earphone antenna. Background technique [0002] In mobile broadcasting, especially in the reception of FM broadcasting (Frequency Modulation Broadcast), earphone antennas (Headset Antenna) are widely used. Other fields such as mobile TV are also one of the main applications, because the earphone antenna can increase the receiving effect. [0003] Since the audio signal line in the earphone antenna and the antenna are integrated in the same group of lines, the signal received by the antenna will be attenuated due to the coupling effect of adjacent lines. This is because for radio frequency signals, the lower frequency audio signal line will be equivalent to the ground, and the receiving ability of the antenna will be reduced due to the adjacent audio signal line. This is one of the main reasons affecting the ...
