Receiver wearable on user's wrist

A receiver comprising:

• a first or wrist-wearable type device comprising radio wave transmission/reception means for transmitting/receiving radio waves, transmission/reception control means for converting the radio waves received by said radio wave transmission/reception means to received data and for sending transmit data to said radio wave transmission/reception means for transmitting purposes, transmit data feeding means for feeding the transmit data to said transmission/reception control means, and radio transmitting means for converting the receive data provided by said transmission/reception control means to a radio signal and for transmitting the same;
• and
• a second or ring-wearable type device comprising radio receiving means for receiving the radio signal transmitted by said radio transmitting means of said first device, and sound generating means for generating a sound based on the radio signal received by said radio receiving means.

A receiver comprising a first or wrist-wearable type device which comprises radio wave transmission/reception means for transmitting/receiving voice radio waves, transmission/reception control means for converting the voice radio waves received by said radio wave transmission/reception means to receive voice data and for sending transmit voice data to said radio wave transmission/reception means for transmitting the transmit voice data as radio waves, transmit voice data feeding means for feeding the transmit voice data to said transmission/reception control means, and infrared transmitting means for converting to an infrared signal the receive voice data received by said transmission/reception control means for transmitting purposes;

• and
• a second or ring-wearable type device comprising infrared receiving means for receiving the infrared signal transmitted by said infrared transmitting means of said first device and sound generating means for generating a sound based on the infrared signal received by said infrared receiving means.

A receiver comprising a first or wrist-wearable type device which comprises radio wave receiving means for receiving voice and image radio waves, converting means for converting the voice and image radio waves received by said radio wave receiving means to voice and image data, sound generating means for generating a sound based on the voice data, and radio image signal transmitting means for converting the image data to a radio image signal and for transmitting the same;

• and
• a second device comprising radio image receiving means for receiving the radio image signal transmitted by said radio image transmitting means of said first device and display means for displaying image data based on the radio image signal received by said radio image receiving means.

A receiver comprising:

• a first or wrist-wearable type device which comprises radio wave receiving means for receiving voice and image radio waves, converting means for converting the voice and image radio waves received by said radio wave receiving means to voice and image data and to provide the same, radio voice signal transmitting means for converting the radio voice data provided by said converting means to a radio voice signal to transmit the same, and radio image signal transmitting means for converting the image data provided by said converting means to a radio image signal and for transmitting the same;
• a finger-wearable subreceiver for receiving the radio voice signal transmitted by said radio voice signal transmitting means of said first device and for outputting a corresponding sound, and
• a second device for receiving the radio image signal transmitted by said radio image signal transmitting means and for displaying a corresponding image.
