The purpose of the developed device is intensifying the emotional perception of an acoustic signal by additional tactile and visual sensations. Close to a powerful low-frequency dynamic speaker, a human body feels vibrations of air and this effect considerably intensifies perception of music. The below-described device generates air vibrations synchronized with the acoustic signal in the infrasonic range. The amplitude of such vibrations is larger as compared to the amplitude of the ones generated by a low-frequency dynamic speaker, so they cause a sensation that the acoustic system is more powerful that it is in realty. A tactile sensation of the air flow is possible in a close distance from the device. However, in case of operation of a smoke generator or waving of flags, the air vibrations will be remarkable in a larger distance.
