ABSTRACT:
A sound-giving tread mat has a bag-like tread mat, a foam rubber sheet interposed in the tread mat, one or more buzzers partly adhered on the inner surface of the lower layer of the tread mat, and a sound-giving electric unit to give out sounds. The buzzer(s) is electrically connected with the sound-giving unit placed on a corner surface of the tread mat or somewhere inside a door in a house. When the tread mat is treaded on with a shoe of a visitor, the buzzer(s) can be vibrated by the compressed air in the tread mat to give out an electric signal, and then the sound-giving electric unit amplifies the electric signal coming from the buzzer(s) and gives out sounds.
