The present invention discloses an improved wireless audio output assembly for projectors, which comprises a system unit having a projector circuit therein and a projector lens disposed on the exterior of the system unit, and the system unit has a card-type wireless audio output circuit installed therein and a wireless active speaker installed on the exterior of the system unit, so that a projector can be used as a standalone device without connecting to external cables to read data from a memory card, view video images, and read audio/video signals of an optical disk. The projector can be upgraded to the user's desired wireless audio output circuit by inserting various different cards for the expansion.
