<div class="detailmodule_html"><div class="detail-desc-decorate-richtext"><p>Features: <br/>1. Using high-quality materials, the product has good frequency stability. <br/>2. Schumann waves are very low-frequency electromagnetic waves that can penetrate any material and are non free radiation. <br/>3. The power interface adopts TYPE-C USB interface, which is convenient to use. <br/>4. Pure sine wave output frequency 7.83Hz Pure sine wave, simulating natural Schumann waves for better results. <br/>5. Convenient design with 3.5mm audio output, compact size, plug and play, easy to place.</p><p>Product Description: <br/>Shumanbo itself does not directly act on sound or video products to improve sound quality, but rather acts on the spatial environment to relax the body and mind, enhance the body&#x27;s perception of sound and images, improve the efficiency of human health work, and relieve psychological pressure.</p><p>Parameter: <br/>Working voltage: DC 5V <br/>Working current: 13-17MA <br/>Power interface: Type-C (supports Type-C to Type-C power supply) <br/>Frequency: 7.83Hz pure sine wave <br/>Signal voltage amplitude: 3V <br/>Audio output: with 3.5MM audio output <br/>Size: 73 * 72 * 26MM <br/>How to use: <br/>1. Use a power supply with TYPE-C interface (phone charger, power bank, etc.). <br/>2. Insert TYPE-C power supply, the LED will flash. <br/>3. Put it where you want to use it.</p><p>Package Include: <br/>1X Schumann wave generator<br/><br/></p></div></div><p><br/></p>
