Abstract

This aims to provide an exhaust engine-sound generating device for generating a sound more similar to such an exhaust engine sound actually as is produced at the explosion and exhaust times of an actual engine. The exhaust engine-sound generating device (K1) comprises a cylinder (21) having intake and exhaust ports (25' and 25), a piston (22) for moving in the cylinder, and intake and exhaust pipes (32a and 32b) connected to the intake and exhaust ports. After the inside of the cylinder (21) is made to be a negative pressure by the movement of the piston, the intake port is opened to suck air, thereby to generate an intake sound with the sucked air. After the air in the cylinder is compressed, the exhaust port is opened to exhaust the air, thereby to generate an exhaust sound with the exhaust air. These intake and exhaust sounds are common on principle to the actual sounds which are generated at the intake and exhaust times of the engine of an actual race car or rally car, and are more similar to the exhaust engine sounds which are generated at the explosion and exhaust times of the actual engine.
