PURPOSE:To attain miniaturization by connecting the 1st coupler and the 2nd coupler coupled to a transmitter and a receiver of a handset to both ends of a band, varying the distance of the couplers, turning the couplers in a prescribed range to the band to make the couplers suitable for another handset. CONSTITUTION:The coupler 6 made of an elastic material to which the transmitter 3 of the handset 1 is fitted and connected is fixed to one end of the band 9 formed by a material having a sufficient elastic force made of plastic or the like via a rotating mechanism 10a. On the other hand, the coupler 5 made of an elastic material to which the receiver 2 of the handset 1 is fitted and connected is fixed to the other end of the band 9 via a rotating mechanism 10b. Further, a flexible conductor wire is provided in the inside of the band 9, connected to a microphone 7 imbedded in the central inside of the coupler 5, and led up to an input section 11 of acousto-electric converting signal together with a wire connected to a speaker 8 imbedded to the central inside of the coupler 6. The difference of the distance between the receiver 2 and the transmitter 3 is absorbed by the elastic force of the band 9 and the difference of the angle is absorbed by the mechanisms 10a, 10b. |
