Untitled V by Marianthi PAPALEXANDRI-ALEXANDRI and Pe LANG
actuator, metal,10 speakers
Size: 600 x 250 mm
Untitled V is a sound sculpture that consists of miniature speakers acoustically activated by a motor driven mechanism. A nylon thread is fastened through a hole at the center of the membrane; the end of the nylon thread is loosely secured to a motor turned rosined wheel to produce friction. Sound is produced by the action of the rim of the rotating wheel rubbing the thread as the wheel is turned. The two surfaces alternating between sticking to each other and sliding over each other, with a corresponding change in the force of friction. The motor speed is reduced at the lowest speed. The slow turn of the wheel creates changes in the tension of the thread, resulting as sounds (crackling impulse) in the membrane of the speaker. Untitled V creates a very quiet listening experience.
