1. A kazoo device comprising: a hollow body having an inlet opening serving for a person's humming and a sound outlet opening; a composite vibrating diaphragm, including a rigid perforated disk having a plurality of holes distributed across its surface and a thin plastic film stretched across the surface of said disk, being peripherally fixed to said perforated disk, said film obstructing said sound outlet opening and; a holding means configured to hold said diaphragm attached to said sound outlet opening, said diaphragm being configured to form an individual membrane fixed at the rim at each of said holes, whereby said individual membranes vibrate during operation at regular vibrating modes yielding a smoothened kazoo device's sound. |
