Adjustable Sine Wave Resonance Generator 0.01Hz-30kHz, Compatible with Physics Audio Testing

This product comes with a Schumann resonance generator, an acrylic box with a small magnet, a USB data cable; Note: The acrylic shell may have a glue smell, which will dissipate if you place them in the sun or a ventilated place for 2 to 3 days. It is recommended to remove the film before use. With an adjustable frequency range of 0.01 to 100000Hz, our sine wave generator allows you to set it according to your needs to improve efficiency and personalization; The default frequency is 7.83Hz, which can also be adjusted to 174Hz, 285Hz, 396Hz, 417Hz, 528Hz, 639Hz, 741Hz, 852Hz, 963Hz, etc. Our audio frequency generator resonator provides multiple waveforms, namely sine wave, square wave and reverse square wave, which are suitable for a wider range of applications and various environments, such as laboratories and studios. The adjustable Schumann resonance generator can emit sine waves to create a relaxing environment, improve your state of mind, and enhance your sense of happiness; it is also a warm gift for friends and family on birthdays, Christmas and other festivals. The sound generator measures about 5.9 x 5.5 x 1.2 inches, and the acrylic box measures about 6.2 x 5.8 x 1.5 inches, which can cover the frequency generator well. Its small size and USB-powered design make it easy to carry and apply at home or during travel. Stable and reliable: The default frequency of the sine wave generator is 7.83Hz, the sine wave voltage amplitude is 3V, and the square wave voltage amplitude is 5V to ensure the stability and accuracy of the output signal. Wide application: This adjustable frequency generator is very suitable for various environments that require signal generation and frequency adjustment, such as electronic equipment testing, equipment calibration, and scientific experiments. Frequency range: 0.01 to 100000 Hz Default frequency: 7.83Hz Power supply voltage: 5V Sine signal voltage amplitude: 3V Square w
