ABSTRACT:
A grunt tube includes a tubular member, a reed and an elastic skin. The tubular member includes a mouthpiece end that allows air to enter, an outlet end that emits sounds and an opening in a wall of the tubular member between the mouthpiece end and the inlet end. The reed vibrates in response to passing air and is disposed within the tubular member adjacent the mouthpiece end and the opening. The elastic skin extends over the wall of the tubular member to at least partially cover the opening. A user can modify sounds emanating from the outlet end produced by air passing through the mouthpiece end and over the reed by selectively applying pressure to the elastic skin. As a result, a varied array of sounds can be produced with the grunt tube.
