A Schumann wave is an electromagnetic wave with an extremely low frequency existing in the earth, excited by lightning discharge, and has a wavelength approximately equal to a circumference of the earth. The frequency of the Schumann wave is controlled by earth ionospheric waveguide, a dominant frequency being about <NUM>, and an alpha wave and a theta wave of a human brain have frequencies also close to <NUM>. Therefore, when reaching the human body, the Schumann wave may harmoniously resonate with a physiological rhythm of a person to assist a running rhythm of a human organ, thereby relaxing the person. Currently, a Schumann wave generator on the market includes a modulation signal circuit and may generate a Schumann wave having a frequency of about <NUM> and possessing amplitude and frequency which change regularly.

In the process of implementing embodiments of the present disclosure, a related art at least has the following problem: due to an influence of reflection of the previously generated Schumann wave, a Schumann wave signal generated by the existing Schumann wave generator is not clear enough, which is unable to well relax the human organ.

In order to have a more detailed understanding of the features and technical content of the embodiments of the present disclosure, the implementation of the embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. The attached drawings are for reference only and are not used to limit the embodiments of the present disclosure. In the following technological description, for purposes of explanation, numerous details are set forth in order to provide a thorough understanding of the disclosed embodiments. However, one or more embodiments may be practiced without these details. In other instances, well-known structures and apparatuses may be shown in simplified forms in order to simplify the drawings.

The present disclosure provides a Schumann wave generating apparatus including a receiving module <NUM>, a modulation module <NUM>, and a control module <NUM>, as shown in <FIG>.

Optionally, a preset condition is as follows: the received Schumann wave signal is the same as a transmitted Schumann wave signal. When having the same waveform as the transmitted Schumann wave signal, the received Schumann wave signal is determined to be the same as the transmitted Schumann wave signal. If reflected in space, a Schumann wave previously generated by the Schumann wave generating apparatus may interfere with the waveform of the Schumann wave currently generated by the Schumann wave generating apparatus, such that the received and transmitted Schumann wave signals have different waveforms; and if not reflected in space, that is, energy of the Schumann wave being exhausted in the propagation process, the Schumann wave previously generated by the Schumann wave generating apparatus may not interfere with the waveform of the Schumann wave currently generated by the Schumann wave generating apparatus, such that the received Schumann wave signal has the same waveform as the transmitted Schumann wave signal.

When the received Schumann wave signal meets the preset condition, the control module <NUM> controls the modulation module <NUM> to increase a generation amplitude of the Schumann wave; and when the received Schumann wave signal does not meet the preset condition, the control module <NUM> controls the modulation module <NUM> to increase a generation interval of the Schumann wave. When the received Schumann wave signal meets the preset condition, the Schumann wave currently generated by the Schumann wave generating apparatus is less influenced by the reflection of the previously generated Schumann wave signal, and the generation amplitude of the Schumann wave signal is increased properly to improve a resonance strength of a human organ and the Schumann wave signal, thus better assisting the running rhythm of the human organ; and when the received Schumann wave signal does not meet the preset condition, the Schumann wave currently generated by the Schumann wave generating apparatus is influenced by the reflection of the previously generated Schumann wave signal, and the generation interval of the Schumann wave signal is increased properly to increase the energy dissipation duration of the previously generated Schumann wave until the generated Schumann wave signal is not influenced by the reflection of the previously generated Schumann wave signal, such that the Schumann wave signal in space is clearer to better assist the resonance of the human organ.

In the embodiments of the present disclosure, according to the Schumann wave signal received by the receiving module <NUM>, the modulation module <NUM> is controlled to adjust the generation state of the Schumann wave, so as to reduce the influence of the reflection of the previously generated Schumann wave, such that the Schumann wave signal in space is clearer and then better relaxes the human organ.

The antenna in the receiving circuit receives the Schumann wave signal in space, the signal is filtered by a band-pass filter formed by the filter circuit, and then, the processed Schumann wave signal is transferred to the single chip microcomputer for arbitration, so as to judge whether the received Schumann wave signal meets the preset condition or not.

The driving circuit is implemented by a bidirectional bridge circuit, and the single chip microcomputer controls two bridge arms by controlling Phase_L and Phase_R, so as to drive the Schumann wave generator Scroll to generate the Schumann wave with an adjustable frequency. When the single chip microcomputer controls Phase_L to output a high level and Phase_R to output a low level, the fourth triode Q4 is turned off, and a current flows from the power source (VCC_24V) to the Schumann wave generator Scroll through the second triode Q2 and then from the sixth triode Q6 to GND; and when the single chip microcomputer controls Phase_L to output a low level and Phase_R to output a high level, the third triode Q3 is turned off, and a current flows from the power source (VCC_24V) to the Schumann wave generator Scroll through the first triode Q1 and then from the fifth triode Q5 to GND. In both states, the currents flowing through the Schumann wave generator Scroll are opposite, such that alternating voltages are generated at two ends of the Schumann wave generator Scroll, so as to drive the Schumann wave generator Scroll to generate a Schumann wave signal with an adjustable frequency.

In some embodiments, the boost circuit includes a boost subcircuit configured to adjust the amplitude of the Schumann wave generated by the Schumann wave generator; and a detection subcircuit provided to be connected with the boost subcircuit and configured to detect an operating current of the boost subcircuit.

Optionally, as shown in <FIG>, the boost subcircuit includes a twelfth resistor R12, a fourteenth resistor R14, a sixteenth resistor R16, a first inductor L1, a fourth capacitor C4, a fifth capacitor C5, a first diode D1, a second diode D2, a seventh triode Q7, and an eighth triode Q8, wherein the fourteenth resistor R14 has a first end connected with the single chip microcomputer and a second end connected with a first end of the eighth triode Q8; the twelfth resistor R12 has a first end connected with a power source (VCC_5.0V) and a second end connected with a second end of the eighth triode Q8; the sixteenth resistor R16 has a first end connected with a third end of the seventh triode Q7 and a second end which is grounded GND; the first inductor L1 has a first end connected with a power source (VCC_3.3V) and a second end connected with a second end of the seventh triode Q7; the fourth capacitor C4 has a first end connected with a second end of the first diode D1 and a second end connected with the second end of the seventh triode Q7; the fifth capacitor C5 has a first end connected with the power source (VCC_24V) and a second end which is grounded GND; the first diode D1 has a first end connected with the power source (VCC_3.3V); the second diode D2 has a first end connected with the second end of the first diode D1; the seventh triode Q7 has a first end connected with the second end of the eighth triode Q8; and the eighth triode Q8 has a third end which is grounded GND.

The single chip microcomputer performs control to output a PWM square wave to control the booster subcircuit, so as to adjust the amplitude of the Schumann wave generated by the Schumann wave generator Scroll. When a PWM signal output under the control of the single chip microcomputer is at a high level, a voltage output to the seventh triode Q7 is at a low level under the inversion action of the eighth triode Q8, and the seventh triode Q7 is turned off; and when the PWM signal output under the control of the single chip microcomputer is at a low level, the eighth triode Q8 is turned off, the voltage output to the seventh triode Q7 is at a high level under the inversion action of the eighth triode Q8, and the seventh triode Q7 is turned on. When the seventh triode Q7 is turned on, a current may be supplied from the power source VCC_3.3V to charge the fourth and fifth capacitors C4, C5; and when the seventh triode Q7 is turned off, the current is unable to change instantaneously due to the first inductor L1, the first inductor L1 continues to charge the fourth and fifth capacitors C4, C5, and a certain voltage exists across each of the fourth and fifth capacitors C4, C5 which are fully charged. The higher the proportion of the low level in the PWM signal output under the control of the single chip microcomputer, the longer the ON time of the seventh triode Q7, the longer the charging time of the fourth and fifth capacitors C4, C5, and thus, the higher the voltage across each of the fourth and fifth capacitors C4, C5. The voltage across each of the fourth and fifth capacitors C4, C5 is an adjustable voltage for driving the Schumann wave generator Scroll, and the amplitude of the Schumann wave generated by the Schumann wave generator may be adjusted by adjusting a voltage value for driving the Schumann wave generator Scroll.

Optionally, as shown in <FIG>, the detection subcircuit includes a thirteenth resistor R13, a fifteenth resistor R15, a seventeenth resistor R17 and a second operational amplifier, wherein the thirteenth resistor R13 has a first end connected with a first end of the second operational amplifier and a second end connected with a second end of the second operational amplifier; the fifteenth resistor R15 has a first end connected with the second end of the second operational amplifier and a second end connected with a first end of the sixteenth resistor R16; the seventeenth resistor R17 has a first end connected with a third end of the second operational amplifier and a second end which is grounded GND; and the first end of the second operational amplifier is connected with the single chip microcomputer.

The purpose of detecting the operating current of the boost subcircuit is achieved by detecting the voltage of the sixteenth resistor R16. A voltage signal processed by the second operational amplifier is transmitted to the single chip microcomputer, and when the voltage signal is greater than a preset voltage signal, the operating current of the boost subcircuit is over-large, such that effective actions are taken to reduce the operating current of the boost subcircuit and guarantee normal and stable operation thereof.
