Portable mini Schumann wave 7.83Hz Ultra-low frequency pulse signal generator (design)

DIY Supplies:ELECTRICAL

About switch design:
  We mainly consider portable in the design, and it is easy to be accidentally closed by the clothes during the process. Therefore, it is necessary to use a nail tip or other fine objects to gently pull the protective switch.
Introduction:
This is a small device with design and very low frequency. Its appearance has changed. We use a portable all-aluminum casing, which is small in size and convenient to carry around. It is -powered and suitable for the following people:
1. Office creative team, brainstorming
2, travel - business people
3, lay, practice, meditation
4, writing, painting, etc. need meditation creators
Schumann's interpretation of excerpts:
Schumann pointed out in 1952 that the Earth and the ionosphere can form a resonant cavity with a special resonant frequency that is determined mainly by the size of the Earth and excited by a global lightning discharge. The resonant frequency is called Schumann Resonance. The Schumann resonance spectrum is in the ELF band with a frequency of around 8 Hz (this value is much higher, 7.83 / 7.5 / 7.2, etc.). The alpha wave and the wave of the human brain are also close to 7.8 Hz , So some people will Schumann resonance known as the "Earth's brain waves."
It is a useful pulsating rhythmic wave that appears in the atmosphere of the ionosphere. Its frequency is 7.83 Hz, just the same as the frequency of the hippocampus in the mammalian brain. "
However, with the continuous improvement of living standards, all kinds of radio waves, electromagnetic waves and other complex radio waves filled with living space, affecting the listening environment.
According to A coustic Revive scientific theory and experiments, Schumann wave (7.83HZ frequency) can reduce the interference of radio and electromagnetic waves, thereby enhancing the details of the music, enhance the S / N, reduce the standing wave. But also can have a positive video upgrade (vividness and contrast), and people will be affected by the impact of Schumann wave can effectively relax, better listen to the details of the sound.
Application:
It is recommended that the product be placed at a height of 1.5 meters and the individual product should not exceed 18 square meters in area. If you exceed 18 square meters, please increase the purchase quantity.
Size: L=76mm * W=57mm * H=13mm
About use:
1,  The portable Schumann wave generator is powered by 3.7V lithium , and the theoretical holding time is 56 hours. It can be charged by using the Android mobile phone charger (
the buyer owns the product, the product does not include the charger
).
2,  Charging using blind charging form, no charging indicator LED lights, basically 3 hours to fully charge.
3.  The outer shell of the product is made of aluminum alloy. It has a certain attenuation to the Schumann wave. Please keep the charging port facing up when you carry it. In other cases, please open the opening of the fuselage.
4,  The fuselage opening and design using the principle of small hole imaging, it has a special meaning of the circular point opening.
5,  The internal use of ultra-high density circular double-sided antenna PCB, it is generally recommended to use a distance of not less than 40cm.
NOTE:
The FM783 Schumann wave generator is an auxiliary device that acts on the human body at a relatively weak frequency, and Schumann wave will fail in the following cases:
1, the surrounding environment is too noisy, all kinds of waveforms far greater than the Schumann wave generator radiation intensity.
2, the body is excited, excited state.
3, each type of continuity under the big volume of DJ music.
