【Earth-Based 7.83Hz Sleep Resonator】 The 7.83Hz frequency generator(Battery Operated) outputs a pure sine wave that cultivates a calm, soothing environment, helping you release stress and restore mind-body balance. On birthdays, Christmas or any holiday or special occasion, it makes a heart-warming gift for family and friends. The included acrylic dust cover keeps the circuit board safe from dust and accidental knocks.
【Stable Performance & Clear Instructions】Defaults to a stable 7.83 Hz output and offers dual voltage amplitudes: 3 V sine wave or 5 V square wave. A digital crystal-oscillator circuit provides an ultra-stable frequency reference, ensuring superior frequency stability and greater immunity to interference. Inside the package, you’ll find a clear user guide that makes operation effortless from the very first tap.
【Wide Frequency Range】 Besides the 7.83 Hz Schumann resonance, the frequency machine features programmable frequency modulation that can be tuned anywhere from 0.01 Hz to 200 kHz. Instantly dial in popular frequencies such as 174 Hz, 285 Hz, 396 Hz, 417 Hz, 528 Hz, 639 Hz, 741 Hz, 852 Hz, 963 Hz, and more—perfectly matching different scenarios and personal needs.
【Battery Operated & Easy to Use】A portable design makes this frequency generator perfect for both bedside use and travel. Equipped with a built-in 1000mAh rechargeable battery, it runs cable-free—ideal for home, office, or on the road. Simple one-hand operation, plus timer, adjustable brightness and backlight levels. All settings auto-save, so it’s ready to go the moment you power it back on.
【13 Waveforms for Versatile Applications】 From Standard Sine/Square/Triangle to Forward/Reverse Sawtooth and 6 advanced mathematical functions (Lorenz, Gaussian, Sinc, Exponential), covering research, signal analysis, and audio testing applications.
【Kind Reminders】1. This product is not a sound machine; headphones or speakers are NOT required for daily use. If you use headphones or speakers, you may only hear beeping sounds. 2. This Schumann Resonance Generator works by emitting an inaudible ultra-low frequency that forms a restorative energy field, supporting your physical and mental well-being. Need help?
