An apparatus is provided for use in connection with a child's toy which selectively generates a noise. The apparatus includes a chamber within a child's toy for holding a volume of air. Adjacent the chamber is a noise-making member, such as a reed, constructed to vibrate when subjected to a moving air stream. The moving air stream is created when the child sits on the toy and rocks back and forth (i.e., rides the toy). When the child rides the toy, air passes from the chamber and over the noise-making member. Surrounding the noise-making member is a tubular member for directing the air from the chamber around and past the noise-making member. The tubular member has an intake port in fluid communication with the chamber adapted to received air from the chamber and an exhaust port adapted to expel air after it has passed over the noise-making member. The apparatus also includes a control knob which supports the tubular member for selectively preventing air from passing over the noise-making member to prevent the noise-making member from producing a noise. Such control knob, when turned, takes the tubular member out of fluid communication with the chamber to prevent airflow across the noise-making member.
