Douk Audio 2021 Schumann Wave 7.83Hz Ultra-Low Frequency Pulse Generator Audio Resonator

Ultra-High-Density Non-Direct Coil Design: This audio resonator features an ultra-high-density non-direct coil design, resulting in a rich, non-directional magnetic field, a balanced electromagnetic field, and excellent sensitivity. This technology enhances musical expression, lowers spatial resistance, and provides a clean, vibrating sound.

Vibration-Improving Technology for Frequency Stabilization: Vibration-improving technology is used to stabilize the frequency. Four 12mm-thick small needles are used to infiltrate acrylic on the PCB, achieving the most direct vibration-damping effect. This makes the generation of Schumann waves more stable and improves the quality of music playback.

Built-In Linear Power Module: The built-in linear power module achieves the same effect as the V1.3, with just a free power adapter. The V1.2 version requires linear power, saving unnecessary costs. This module improves the performance of the Schumann wave generator and helps bring music to life more vividly. ... This allows you to tailor the sound to your personal preferences and circumstances, providing a more comfortable listening experience. Magnetic Bit Coexistence and Indicator Off Function: The magnetic field antenna and the bit field antenna are successfully integrated to achieve magnetic bit coexistence. All indicators can also be turned off, minimizing visual interference and allowing you to fully enjoy your music.
