Abstract
A broadcasting method using a PDA as a signal relay device has the steps of (a) modulating a sound file intended to be broadcast, wherein the sound file stored in a PDA is modulated in the form of a radio wave at a set frequency, (b) transmitting the modulated radio wave, (c) demodulating and (d) playing the radio wave to obtain the sound file by any radio device. A broadcasting apparatus utilizes a modulating module that is integrated into a charging base of the PDA to modulate sound files stored in the PDA. the modulated sound files can be transmitted in the form of a radio wave and then be demodulated and played by any radio receiving device.

A broadcasting method using a PDA as a radio relay device, the method comprising the steps of:
- setting a modulation frequency by the PDA;
- modulating a sound file stored in a PDA and intended to be broadcast, wherein the sound file is modulated in the form of radio wave at the set frequency;
- transmitting the modulated radio wave;
- demodulating the radio wave to obtain the sound file;
- and
- playing the demodulated sound file.
A broadcasting apparatus using a PDA as a radio relay device, the apparatus comprising:
- the PDA with sound files stored in the PDA, wherein management software in the PDA selects the sound file to be broadcast and sets a broadcast frequency;
- and
- a modulating module electrically connected to the PDA to modulate the selected sound file in the form of a radio wave at the set frequency, wherein the radio wave is further transmitted by the modulating module.
