Silent ultra-low frequency sound wave multimedia interaction system device

Abstract

The invention discloses a silent ultra-low frequency sound wave multimedia interaction system device. The device comprises a first general waveform generator and a second general waveform generator; two general waveform generators form connection with a first signal integration unit and obtain a ultra-low frequency sound wave by utilizing audio difference; the first signal integration unit is connected with an effector; the effector forms connection with a general signal amplifier through a second signal integration unit; the general signal amplifier forms connection with a loudspeaker, an absorptive-filtration audio layer is covered on the periphery of the loudspeaker, the absorptive-filtration audio layer is used for absorbing and filtering the external noise; the absorptive-filtration audio layer is spacing from the periphery of the loudspeaker; the device can produce the silent sound wave in co-frequency band and resonance with the brain wave, a piezoelectric material is paved on the ground as the power source; the LED and a sound device can be combined so as to play the brain wave co-frequency band sound wave for relaxing and focusing the people through the setting, an operation of externally connecting a power supply structure is avoided, and the device is more suitable for various space conditions.

Description

technical field [0001] The invention relates to a multimedia interactive system device, in particular to a silent ultra-low frequency sound wave multimedia interactive system device. Background technique [0002] Resonant music with the same frequency as brain waves has been widely known in recent years. Many large medical institutions have recognized and introduced it as a medical aid to stabilize emotions, develop potential, and help sleep. According to the existing method, the user achieves effects by listening to music that emits special frequencies. However, the sound waves that can resonate with brain waves belong to the ultra-low frequency range, which is not a frequency band that can be directly generated by ordinary audio equipment. [0003] When two voices sound at the same time, physically, in addition to their respective frequencies, they also produce frequencies that are different from each other. When the frequencies of the two sounds are closer, the frequency...

Problems solved by technology

[0011] In summary, the disadvantage of the existing brain wave resonance equipment is that the production requirements are high, and the electromagnetic waves tend to be relatively strong due to the high demand for electronic circuit components.
