A wireless transmission-AV system for an outdoor furniture includes a speaker unit built-in with a furniture frame and a wireless control electrically connected to the speaker unit for wirelessly linking an AV player with the speaker unit, wherein the wireless control has a wireless range covering an area of the furniture frame in such a manner that the speaker unit is adapted for generating an audio signal wirelessly transmitted from the AV player through the wireless control when the AV player is located within the wireless range. Therefore, the user is able to wirelessly link his own AV player to the wireless transmission-AV system to listen to his own music.
