Portable terminal unit and sound reproducing system using at least one portable terminal unit

A sound reproducing system comprising:

• at least one portable terminal unit, selected from the group consisting of portable telephone, personal handy phone system (PUS), cordless telephone, child unit of a party line, and personal digital assistant (PDA), the portable terminal unit being adapted for acquiring data including sound data, each of the at least one portable terminal unit comprising:
• a sound data reproducing portion adapted for receiving the sound data and decoding the sound data into an analog sound signal, the sound data being in a digital format;
• and
• at least one loudspeaker coupled to the sound data reproduction portion, the loudspeaker being disposed for receiving the analog sound signal and reproducing an audible sound corresponding to the sound data and in cooperation with at least one sound device, one of said at least one sound device being the source of said sound data, to give listeners the feeling of being at a live performance by having the portable terminal reproduce the audible sound synchronously with said at least one sound device when said sound data is reproduced, with said sound data shared by the portable terminal and said at lease one sound device,
• wherein each at least one portable terminal unit is disposed at mutually separate locations and the reproduced audible sound is a front-left sound FL, a front-right sound FR, a rear-left sound RL, a rear-right sound RR, and a low sound LOW of a low frequency range.

A sound reproducing system comprising:

• a plurality of portable terminal unit, selected from the group consisting of:
• portable telephone, personal handy phone system (PUS), cordless telephone, child unit of a party line, and personal digital assistant (PDA), the portable terminal unit being adapted for acquiring data including sound data, each one of the plurality of portable terminal unit comprising:
• a sound data reproducing portion adapted for receiving the sound data and decoding the sound data into an analog sound signal, the sound data being in a digital format;
• and at least one loudspeaker coupled to the sound data reproduction portion, the loudspeaker being disposed for receiving the analog sound signal and reproducing an audible sound corresponding to the sound data and in cooperation with at least another one of said plurality of portable terminal units, to give listeners the feeling of being at a live performance by having the portable terminals synchronously reproduce the audible sound when said sound data is reproduced, with said sound data shared by respective terminals or divided and utilized by respective terminals,
• wherein each portable terminal unit is disposed at mutually separate locations and the reproduced audible sound is a front-left sound FL, a front-right sound FR, a rear-left sound RL, a rear-flight sound RR, and a low sound LOW of a low frequency range.

A sound reproducing system comprising:

• a plurality of portable terminal unit, selected from the group consisting of:
• portable telephone, personal handy phone system (PHS), cordless telephone, child unit of a party line, and personal digital assistant (PDA), the portable terminal unit being adapted for acquiring data including sound data of low frequency range and sound data of high frequency range,
• at least one of the plurality of portable terminal unit comprising:
• a sound data reproducing portion adapted for receiving the sound data of low frequency range and decoding the sound data of low frequency range into an analog sound signal, the sound data of low frequency range being in a digital format;
• and
• at least one loudspeaker coupled to the sound data reproduction portion, the loudspeaker being disposed for receiving the analog sound signal and reproducing an audible sound corresponding to the sound data of low frequency range and in cooperation with at least another one of said plurality of portable terminal units, to give listeners the feeling of being at a live performance by having the portable terminals synchronously reproduce the audible sound when said sound data of low frequency range is reproduced, with said sound data of low frequency range shared by respective terminals or divided and utilized by respective terminals;
• and
• at lease one of the plurality of portable terminal unit comprising:
• a sound data reproducing portion adapted for receiving the sound data of high frequency range and decoding the sound data of high frequency range into an analog sound signal, the sound data of high frequency range being in a digital format;
• and
• at least one loudspeaker coupled to the sound data reproduction portion, the loudspeaker being disposed for receiving the analog sound signal and reproducing an audible sound corresponding to the sound data of high frequency range and in cooperation with at least another one of said plurality of portable terminal units, to give listeners the feeling of being at a live performance by having the portable terminals synchronously reproduce the audible sound when said sound data of high frequency range is reproduced, with said sound data of high frequency range shared by respective terminals or divided and utilized by respective terminals,
• wherein each portable terminal unit is disposed at mutually separate locations and the reproduced audible sound is a front-left sound FL, a front-right sound FR, a rear-left sound RL, a rear-fight sound RR, and a low sound LOW of a low frequency range.
