An electronic martial arts training device is disclosed. The martial arts training device of the present invention includes a pliable substrate of sufficient thickness to absorb a full impact martial arts blow without injuring the deliverer thereof. A pictorial representation of a martial arts combatant is disposed on one surface of the pliable substrate and a plurality of target lights are disposed within the pliable substrate beneath the pictorial representation at locations which correspond to the "vital-points" of the pictured combatant. Mounted within the pliable substrate in conjunction with each target light is a miniature loud speaker having a vibratable cone and a pair of electrical terminals which are coupled to the vibratable cone via a movable coil. Vibrations induced into the vibratable cone by the impact of a martial arts blow will result in an electrical signal being generated at the electrical terminals. A control circuit is then utilized to selectively illuminate the target lights and couple the electrical signal output by each associated miniature loud speaker to a scoring indicator which provides an indication of a student's proficiency.
