摘要:
An earphone antenna is provided in which two pairs of audio/high-frequency signal lines respectively corresponding to left and right earphone units are connected to a balun. The left and right earphone units are connected to terminals of the two pairs of audio/high-frequency signal lines remote from the balun via loading coils, respectively. The terminals of the two pairs of audio/high-frequency signal lines remote from the balun are further connected to each other by a pair of conductive lines via audio blocking means. The earphone antenna having such a structure can eliminate high-frequency adverse effects on a wireless device transmitted from a human body via an earphone.
