Abstract: A system for dampening sound produced by an air blower such as that used to inflate an inflatable movie screen or other inflatable structures. The system can include an air blower and a muffler. The muffler is configured to reduce or dampen sound output from the air blower and includes one or more surfaces that enclose at least a portion of the blower. An opening may be formed in the muffler to facilitate air flow into the air blower. The blower can include a fan and the opening may allow air to pass through into a space in the interior of the muffler and to the fan, so that it can be output to the inflatable movie screen. The muffler may also include a second opening. The second opening can facilitate output of the air by the blower and to the inflatable movie screen.

Abstract: An inflatable moving screen system includes an inflatable support structure. The inflatable support structure has at least two horizontal tubes and at least two vertical tubes that collectively form a rectangular frame. A skirt is coupled to one of the horizontal tubes and to both vertical tubes. An air inlet is also provided in the support structure, so that as air is received, it can fill the support structure tubes. A projection surface is disposed within the rectangular frame and is permanently coupled directly to one of the horizontal tubes, to both vertical tubes, and to the skirt. An internal tension mechanism is also included. The skirt may be part of the internal tension mechanism, which is configured to create fully internal tension to stretch the projection screen automatically, by inflation of the four inflatable tubes, and without using external or removable tension mechanisms.
