PURPOSE : A wireless telecoil receiver using a magnetic field generated by a necklace-type electric wire is provided to eliminate a howling phenomenon of a voice while being minimized in size, and to realize an electromagnetic protection film effect by being affected with rare electromagnetic interference of other peripheral electromagnetic generators. CONSTITUTION : A wireless receiver consists of a telecoil, a capacitor, an amplifier, a battery, a battery door, and a volume controller. The wireless receiver forms a magnetic field with a home frequency band by amplifying an output signal of a microphone and conducting a current of the amplified output signal to a necklace-type circular electric wire. © KIPO 2006
