A sound generating toothbrush has a sound generating apparatus and a switch device for activating the sound generating apparatus. The toothbrush has a handle portion with a compartment provided adjacent to the proximate end thereof for accommodating the sound generating apparatus and the switch device. The switch device has a bush-button which is located at the proximate end of the handle. Consequently, the sound generating apparatus can be activated, while normally holding the handle portion of the toothbrush, by momentarily pressing the proximate end of the toothbrush handle against any appropriate surface.
