PROBLEM TO BE SOLVED: To provide an infrasonic wave generating apparatus, which is a portability type based on outdoor use, efficiently and stably generates an infrasonic wave of a specific frequency with large sound pressure, and performs an experiment without allowing a power generator or the like to operate having the risk of generating low frequency sound noise.SOLUTION: An infrasonic wave generating apparatus 1, which includes diaphragms to be driven by compressed air, includes the diaphragms 2, an air pressure servo actuator 3 for driving the diaphragms 2, and an air tank for feeding compressed air to the actuator 3. Then, the infrasonic wave generating apparatus is formed so that the diaphragms is respectively disposed on opposed two faces and the two diaphragms are driven with opposite phases. |
