摘要： An earphone antenna is provided that can eliminate high-frequency adverse effects on a wireless device transmitted from a human body via an earphone. The earphone antenna can ensure receiver sensitivity required for a signal in a wide frequency range without any sensitivity control operation and can transmit audio signals from a television receiver to an earphone unit. Two pairs of audio/high-frequency signal lines (8La), (8Lb), (8Ra), and (8Rb) corresponding to the left and right earphone units (12L) and (12R) are connected to a balun (4). Terminals of the two pairs of audio/high-frequency signal lines remote from the balun are connected to the left and right earphone units (12L) and (12R) via loading coils (LLa), (LLb), (LRa), and (LRb). 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 (20a) and (20b). The loading coils (LLa), (LLb), (LRa), and (LRb) have low impedance for a fundamental frequency and have high impedance for blocking a specific frequency higher than the fundamental frequency. In addition, the two pairs of audio/high-frequency signal lines (8La), (8Lb), (8Ra), and (8Rb) are used as transmission means for transmitting audio signals to the left and right earphone units (12L) and (12R).
