Adjustable 0.001Hz-200KHz 7.83HZ Schumann Resonance UltraLow Frequency PulseWave Generator Audio Resonator

SchumannWave itself does not act directly on sound or video products to improve sound quality, but on the space environment, which can relax people's body and mind, improve the body's perception of sound andimages, improve thehealth of the human body and work efficiency, and relieve psychological pressure. This product not only can output 7.83Hz SchumannWave, but also can adjust the frequency in the range of 0.001Hz-200KHz, the digital circuit crystal oscillator frequency reference, more stable and strong anti-interference.

Features:
Using fine quality materials, the frequency stability of the product is fine.
This product can not only output 7.83Hz SchumannWave, but also adds programmable frequency modulation technology, which can adjust the frequency within the range of 0.001Hz-200KHz.
Professional oscilloscope measuremen, 7.83Hz standard sinewave, Waveform is real and effective.
Digital circuit crystal oscillator frequency reference, more stable and strong anti-interference.
The powersupply interface adopts DC5.5*2.1 interface, which is easy to use, and the USB can be plugged into the powerbanks or USB charginghead or other USB powersupply equipment to work.
