Embodiment Construction
[0025] A high-energy infrasonic sound wave instrument, including a microprocessor that outputs infrasound electrical signals, a white noise generating circuit that generates low-frequency electrical signals, a synthesis circuit, and a sound power adjustment circuit. The synthesis circuit receives the infrasound electrical signals input by the microprocessor , The white signal filtered by the low-pass filter, the low-pass filter turns the low-frequency electrical signal generated by the white noise generating circuit into a white noise noise signal below 300Hz; the synthesis circuit is to convert the infrasound electrical signal, low The audio electric signals are superimposed together; the synthesis circuit is followed by the sound power adjustment circuit, which is composed of three sets of resistors and switches connected in parallel to adjust the sound power, and the sound power is adjusted and classified into three rated infra-frequency electric signals ; The sound power adj...
