ABSTRACT:
An educational drawing toy with sound-generating function has a resilient whiteboard, plural sets of contacts arranged in the form of a matrix underneath the resilient whiteboard, and a sound-generating circuit electrically connected to the plural sets of contacts. Under the action of pen pressures applied upon drawing a picture on the whiteboard, the plural sets of contacts are selectively and successively brought into contact with each other to actuate the sound-generating circuit so that a scale or plural melodies can be selectively played.
