Prior art

Patent RU2284584 is the closest analog of the present invention. Patent RU2284584 describes a method of enhancing emotional perception of auditory sound by generating an infrared signal whose frequency is related to the non-linear dependence of auditory audio frequency. The said patent describes the theoretical bases and algorithms of the required frequency infrared signal isolation. The following are possible means for reproducing infrared vibrations: special dynamic speakers and tubes for air media; magnetostrictive and piezoelectric transducers for higher density media. Since the required amplitude of the infrared vibrations must be greater than the amplitude of the audible vibrations, the practical application of the described technology is difficult because it requires very powerful bulky and expensive emitters.

The essence of the invention

Of the various known ways of transmitting infrared vibrations to man, the most practical and simple is the effect through visual perception. For this purpose, the mathematical processing of an audio signal must distinguish a single frequency within its infrared range. This frequency, in the form of a logic signal, is used to synchronize video animation on screen or strobe light.

Another easy implementation is related to the generation of mechanical vibrations on hard surfaces. A crank mechanism is used for this purpose. The advantages of this technique are higher efficiency and simplicity compared to magnetostrictive or piezo-crystalline methods and it generates vibrations of sufficient power. The disadvantages of the crank mechanism include its high inertia and noisy operation. By the way, inertia does not appear to be a disadvantage when the rhythm of the music being played is constant. Noise reduction is achieved by the use of a brushless motor, belt drive gearbox and spacers for damping high-frequency vibrations. With prolonged exposure, vibration amplitudes of less than one millimeter of vertical floor can be achieved.

The present invention relates to a method of enhancing emotional perception of rhythmic sounds by using a crank mechanism for generating vibrations together or separately with modulated light signals. Using infrared oscillator oscillators without synchronization with music may lead to changes in the emotional state, but in this case such vibrations are treated as extraneous stimuli.

An example embodiment of the invention

An example is the trans style music taken on the ground. The playback music signal is fed to an analog 100-200 Hz bandpass filter. Based on the amplitude of the filtered signal, the microcontroller determines the magnitude of the period, which can be, for example, 0.4 s. The resulting 2.5 Hz frequency is multiplied by four to give an alpha-rhythm of ten hertz. Synchronized in this way with the music, the signal is fed logically into the keys for the control of the fluorescent lighting under UV light. A mechanical vibrator with eccentric is placed in an airtight housing and buried in the ground. The eccentric rotation speed is synchronized with the preset alpha rhythm of the electronic controller. If the floor on which many people dance rhythmically is not very hard, the vibration sensation of the floor is similar to that of the natural vibration of such a floor, only the vibration frequency is higher.

The use of an individual compact infrared vibrator consisting of a microphone and a vibration frequency calculation and control scheme is permitted.
