PURPOSE: A thin audio teaching machine is provided to remove a care about trouble and to make manipulation easy by simplifying components and reducing the thickness. CONSTITUTION: A thin plate type audio teaching machine comprises: a touch plate(10) formed in a thin plate shape; a base plate(20) attached on the rear face of the touch plate; a gap sheet(40) attached on the inner faces of the touch plate and the base plate, interposed between conduction switch circuits(30,31), forming a gap for isolating the conduction switch circuits from each other, and having a hole(41) at a touch position of the content printed on the front face of the touch plate and through which the conduction switch circuits are in contact with each other; a voice chip outputting a stored audio signal when contact point signals are applied from different positions by the interconnection with the conduction switch circuits; a speaker(60) outputting the audio signal with a voice by the interconnection with the voice chip; and a battery(70) connected with the voice chip for power supply. The entire structure of the audio teaching machine is thin. Thus, production and manipulation are convenient. According to a low cost, the price of a product is reduced.
