| 摘要 |
The present invention is a noise making device comprising a two-part tubular structure including a mouthpiece and a tube. The mouthpiece is connected to the tube in the lengthwise axis. During the course of user operation, the free-end of the tube is disposed into the users armpit and the mouthpiece is disposed to the user's mouth. Air is then blown into the mouthpiece through the lengthwise axis of the noisemaker and is expelled from the end of tube. This expulsion of air generates vibrations at the end of the tube, surface of the user's armpit and into the surrounding air. Such vibrations in turn generate sound. In addition, two slits have been applied in one end of the tube. Inclusion of these slits enhance the generation of the aforementioned vibrations and impart discrete sounds to the noisemaker.
