REDUCED RADIATION AUDIO HEADSET

摘要

An apparatus in the form of an audio headset for use with, for example mobile telephones, computers, hand-held computers, Personal Digital Assistants (PDAs) or the like in which the loudspeaker and the microphone are contained within an enclosure and the communications link between the loudspeaker of said headset and the earpiece of said headset is a non-metallic acoustic conduit, for example a silicon rubber tube. By forming the communications link from a non-metallic material which cannot act as a conduit for microwave radiation the microwave radiation generated by the said telephone and incident at the user's head is significantly reduced compared to an audio head-set whereby the communication link to the said earpiece is made from electrical wires.
