    • Headset apparatus, particularly applicable for use with a mobile phone (1), or similar equipment, is connected via signal converter (5) which converts electrical signals received via the phone (1) to an acoustic signal for transmission via sound pipe (7) to an earpiece (11) of a headset (10). The headset (10) comprises an optical microphone (12) which modulates a light signal received on optical fibre (8) from a light source (14). The modulated light signal is returned to opto-electronic converter (17) which converter (17) generates an electrical signal conveying any acoustic signal received by the microphone (12) to mobile radio (1). The invention avoids the requirement for any electrical connection between the mobile radio and a headset (10), and thus avoids any radiation hazard which could otherwise due to radiation from the antenna of a mobile phone being conducted through the electrical conductors of a conventional headset.
    • 特别适合于与移动电话(1)或类似设备一起使用的耳机装置通过信号转换器(5)连接,信号转换器(5)将通过电话(1)接收的电信号转换成声音信号,以通过声管(7)传输, 到耳机(10)的耳机(11)。 耳机(10)包括光学麦克风(12),其从光源(14)调制在光纤(8)上接收的光信号。 调制光信号返回到光电转换器(17),该转换器(17)产生将由麦克风(12)接收的任何声信号传送到移动无线电(1)的电信号。 本发明避免了对移动无线电与耳机(10)之间的任何电连接的要求,并且因此避免了否则由于来自移动电话的天线的辐射被传导通过常规耳机的电导体的辐射危害。
