Collapsible portable acoustic tower

A system for raising a panel of an acoustic tower, wherein said acoustic tower comprises at least a first panel and a second panel, and wherein said second panel is movable between a storage position and a performance position relative said first panel, said system comprising:

• a first support structure secured to said first pane, wherein said first support structure has a longitudinal opening therethrough;
• a second support structure secured to said second panel, said second support structure positioned relative said first support structure so as to be slidable within said longitudinal opening of said first support structure;
• and
• an assembly comprising a line and a line winder, wherein said line winder is located proximate said first support structure, and wherein said line is secured to said line winder and to said second support structure, and wherein the winding of said line by said line winder slides said second support structure within said longitudinal opening and lifts said second panel from said storage position to said performance position.

An acoustic tower adjustable between a storage position and a performance position, said acoustic tower comprising:

• a first acoustic panel including a cavity for insertion of a lifting tool;
• a second acoustic panel having a first end and a second end, wherein said first acoustic panel is rotatable about said first end and wherein said first acoustic panel is rotatably raisable to said performance position at one of a plurality of preset angles;
• and
• a third acoustic panel having a first end and a second end, wherein said second acoustic panel is slidably secured to said third acoustic panel, and wherein said second acoustic panel is slidable between said storage position, proximate and substantially parallel said third acoustic panel, and said performance position, above said third acoustic panel wherein said second end of said second acoustic panel and said first end of said third acoustic panel are in substantial vertical alignment.

A method of assembling an acoustic tower to a performance position, said acoustic tower having a first acoustic panel having a first panel cavity, a second acoustic panel defining a substantially vertical plane and having a first end and a second end, said first acoustic panel rotatable about said first end, and a third acoustic panel having a first end and a second end, said second acoustic panel slidably secured to said third acoustic panel, the method comprising the steps of:

• rotatably lifting said first acoustic panel from a storage position to said performance position at one of a plurality of pre-set angles relative said substantially vertical plane by inserting a lifting tool in the first panel cavity;
• maintaining said raised first acoustic panel at said one of said plurality of pre-set angles;
• and
• slidably lifting said second acoustic panel from a storage position to a performance position wherein said second acoustic panel is in substantial vertical alignment with said third acoustic panel.
