Schumann wave itself is not directly acting on the sound or video products to improve the quality of sound quality, but the role of the space environment, people's physical and mental relaxation, improve the body's perception of sound and images, improve the health of the human body to improve the efficiency of work, mental stress also have a better effect. This product can not only output 7.83Hz Schumann wave, but also can adjust the frequency within the range of 0.01Hz~30KHz, digital circuit crystal oscillator frequency reference, more stable, stronger anti-interference PCB Board Size: 150*150*12MM Weight : 108g Waveform: Sine Wave(can't output Other waves) Power supply interface: DC 5.5*2.1 Supply voltage: DC 5V Rated power consumption:
