Abstract
An acoustic device is described that comprises an acoustic channel extending through its housing and an acoustic valve disposed in the acoustic channel. The acoustic valve is configured to determine a passage of sound through the housing via the acoustic channel. The acoustic valve comprises a deformable shape forming a deformable perimeter of the acoustic channel, and an actuating mechanism configured to exert an actuating force deforming the deformable shape causing the deformable perimeter to move and change the passage of sound.
