Abstract
Th present invention is related to a modification made on a regular toy tumbler to let the toy tumbler be equipped with a sound generating IC controlled by a plate spring type microswitch. When the toy tumbler stands still, the microswitch is OFF, and no sound is generated. When the toy tumbler is rocking, the microswitch is ON, and the sound generating IC is triggered to provide audio signal through an electronic speaker. Matching with the innovative outer appearance, the toy tumbler is bestowed with a new life.
