ABSTRACT:
A rear projector has a lower cabinet disposing an image generator and an upper cabinet for a screen body to be mounted, two woofer boxes being mounted on the front side of the lower cabinet and high-pitched sound speaker boxes being respectively mounted on the right and left lateral sides of the upper cabinet, so that, since the woofer box is disposed in the lower cabinet, vibration is not easily transferred to a screen body on the upper cabinet and a reflection mirror inside the upper cabinet, thus avoiding flicker of the image on the screen body even when great volume of sound is outputted by the woofer box.
