Blinvcra Frequency Generator for Healing, Adjustable Schumann Resonance Generator 7.83Hz, 0.01Hz–30kHz Sine Wave Frequency Machine, USB Powered with Acrylic Case for Relaxation, Sleep and Meditation

• 【7.83Hz Earth-Inspired Frequency】Preset at 7.83Hz, this frequency generator is inspired by the Earth’s natural resonance and is designed to help create a calm, balanced atmosphere for relaxation, meditation, yoga, and rest.
• 【Adjustable 0.01Hz–30kHz Range】With a wide adjustable range from 0.01Hz to 30kHz, this device gives you the flexibility to explore different frequency settings for personal preference, sound experiments, and daily wellness routines. Simple controls make adjustment quick and easy.
• 【Clear Acrylic Case & USB Powered Design】Built with a durable clear acrylic housing, the device helps protect internal components from dust and everyday handling while maintaining a clean, modern look. The USB-powered design makes it convenient to use at home, in the office, or while traveling.
• 【Compact for Everyday Use】Small, lightweight, and easy to place, this frequency generator fits naturally on a bedside table, desk, or meditation corner. It is designed for daily use during quiet routines such as yoga, reading, meditation, or winding down before sleep.
• 【Two Simple Ways to Check Output】Because the generator itself operates silently, the package includes a Schumann wave detector and wired headphones for output confirmation. You can verify the signal either by checking it directly with the detector or by using the headphones, making the device easier to understand and use.
• 【Easy Frequency Testing Guidance】The included detector responds to frequencies from 1–100Hz and should be placed at the center of the unit during testing. The wired headphones respond to 1–15kHz. If your selected frequency falls outside either response range, it is normal that the detector shows no movement or that no sound is heard through the headphones. The detector and headphones are intended only for signal checking purposes.
