Abstract
PURPOSE:To ensure a highly efficient transmission of signal and at the same time realize a supply of necessary power to the handset part, by providing a mobile coil into a handset of electromagnetic coupling system and thus maintaining the best electromagnetic coupling at all times between the mobile coil and the induction coil for main body of the telephone. CONSTITUTION:The transfer of signal current is carried out between the telephone main body 11 and the induction coil 9 provided on the floor or the ceiling of a car, and the transmission of signal is performed between the main body 11 and the handset part 10 by the electric field generated at the coil 9. The induction coil 15 wound round the ferrite core 16 is provided into the handset 10, and the core 16 is hanged down via the nylon lope 13. The coil 15 is always held horizontally by the empty weight of the core 16, and thus an electromagnetic couplng is always secured between the coils 15 and 9 in the best condition. At the same time, the main body 11 transmits the prescribed frequency to secure a supply of the necessary power to the part 10.
