A wireless beam projector using a radio frequency is provided to allow a user to use a device conveniently by transmitting a signal without special software. In a wireless beam projector using a radio frequency, a signal generated from various playing apparatuses(1) is transformed into a signal and output through an RGB signal generation unit(2). A DAC(Digital to Audio Converter)/audio signal transmitting unit(3) transforms the signal into an image and audio signals and transmits the transformed signals. And the signal is amplified by a signal amplifier(4) for having no influence on noise or environment and transmitted to a beam projector through a wireless transmission unit(5) by a specific low output of 2.4 Ghz. |
