This ultra-low frequency pulse generator operates with Schumann waves at 7.83 Hz, delivering high accuracy and stability, and comes with an MSDS certificate for safety assurance.

The frequency acquisition parts are designed for high stability, featuring a high-stability pulse chip, precision correction capacitance, and a precision adjustable multi-loop resistance.

It is powered by a high-quality polymer battery with built-in protection against overcharge, overvoltage, and overcurrent. The power supply exhibits almost no ripple, ensuring pure operation.

Equipped with a working switch, this device is easy to operate. Schumann waves can be applied to HIFI audio environments or to improve sleep.

This rechargeable model is small and portable, including a 20 cm charging cable. The circuit design is newly optimized with a gold-plated starting circuit for enhanced performance.

Please note that Schumann waves do not directly act on audio or video products to improve sound quality. Instead, they act on the surrounding space environment, relaxing the body and mind, improving human perception of sound and images, promoting better health, increasing work efficiency, and helping to alleviate mental stress.

This device is suitable for use in audiovisual spaces, bedrooms, offices, innovative spaces, tea ceremonies, and spaces dedicated to realization and truth.
