[0033] As shown in the figure, Figures 1 to 3 The frequency conversion sound and light brain wave frequency modulator according to the first aspect of the utility model, comprising a sound and light triggering module, a program building module, a display control module and a user operation module.
[0034] The sound and light triggering module is used for transmitting instructions to the central processing unit, generating rhythm sound and different colored light of different frequencies as a parameter adjustable sound and light exciting unit. The program building module is used for building different program modules by using each sound and light unit, including time length, amplitude, frequency, phase and the like. The display control module is used for outputting program number to the display according to user operation. The user operation module is used for receiving user operation signal and outputting instructions to CPU for running processing.
[0035] According to the embodiment of the utility model, the specific working process and working principle of the variable frequency sound and light brain wave frequency modulator are as follows: when starting, the user first performs simple operation through the hardware equipment of the variable frequency sound and light brain wave frequency modulator, for example, turning on the power by lightly pressing the power button 5. Once the equipment starts, the user operation module is ready, waiting for further instructions from the user. The user can browse and select the preset program number through the up / down button on the operation panel, and these programs contain sound and light combinations customized for different needs. After selection, the user operation module converts these instructions into signals recognizable by the CPU, and then triggers the corresponding program to run.
[0036] At this time, the central processor activates the sound and light trigger module according to the received instructions. The function of this module is to send accurate instructions to the central processor according to the program parameters selected by the user, in order to generate rhythmic colored light and variable frequency rhythm sound of specific frequency. The frequency, amplitude, waveform, duty cycle and other parameters of these sound and light signals are carefully designed to resonate with human brain waves, optimize mood, mental state or promote cognitive function.
[0037] At the same time, the program building module plays a core role, which is responsible for integrating sound and light units to build complex program modules with multiple dimensions such as time length, amplitude, frequency and phase. The setting of each module is to achieve specific physical and mental regulation goals, such as improving concentration, relaxing mood or promoting sleep. These program modules are finely adjusted by bottom programming control signals to ensure that the output of sound and light stimulation is consistent with the physiological rhythm of the human body.
[0038] During operation, the display control module will feed back the current program number or related running state to the display, so that the user can understand the working condition of the equipment in real time. In addition, the user can also adjust the loudness of the sound and the intensity of the light according to personal preference, using the volume and brightness adjustment knobs 9, to achieve the best experience effect.
[0039] In summary, the variable frequency sound and light brain wave frequency modulator of the utility model realizes precise control and output of sound and light signals through the cooperation of highly integrated hardware and software, in order to achieve the regulation and optimization of the user's brain wave state, and then affect and improve the mood, energy, cognitive ability and other comprehensive effects of the physical and mental levels. The whole working process is simple and efficient, user-friendly, and can be personalized according to individual needs, improving the user experience.
[0040] It needs to be explained that the variable frequency sound and light brain wave frequency modulator is an advanced brain wave frequency modulation optimization system for personal mood, energy, brain regulation and physical and mental growth. The utility model provides a sound and light synchronous excitation frequency modulation electronic device, the main functions include: rhythmic colored light generation, variable frequency rhythm sound generation, controllable output of sound quality / color / light color, and synchronous output of sound and light.
[0041] The sound-light excitation frequency modulation electronic device is mainly based on a brain-computer interface technology, adjusts brain wave states through unique sound-light technology, converts various consciousness states, adjusts positive emotions, good sleep, vigorous energy, brain vitality excitation and other beneficial physical and mental states. The device contains multiple programs formed by complex algorithms, designed to adjust each specific physical and mental state. The sound-light excitation frequency modulation device of the utility model combines the generation and processing technology of sound signals and optical signals, and effectively applies in the frequency adjustment of brain nerve bioelectricity.
[0042] In the related art, generally, emotion treatment of human brain waves based on a brain-computer interface technology mainly includes two technical routes, namely, an invasive route and a non-invasive route. The invasive brain-computer interface electrode mainly includes a rigid electrode and a flexible electrode, and the non-invasive brain-computer interface mainly includes three types of wet electrodes, dry electrodes and semi-dry electrodes.
[0043] The invasive brain-computer interface is a brain-computer interface technology in which an electrode or a probe is inserted into the cerebral cortex for signal transmission. The invasive brain-computer interface generally adopts rigid electrodes and flexible electrodes, has good signal accuracy and stability, can provide good control accuracy and response speed, but needs to be physically implanted on the human head, has certain risks in terms of population adaptability, and has irreversible recovery of physical damage to the human head.
[0044] The non-invasive brain-computer interface refers to a technology for signal interaction through an electrode array placed on the scalp without cutting the skull or implanting electrodes in the brain, for influencing and improving human emotions, to realize human-computer interaction. The non-invasive brain-computer interface commonly uses non-invasive signals such as scalp electroencephalogram (EEG), functional near-infrared spectroscopy (fNIRS) and magnetoencephalogram (MEG), generally adopts wet electrodes, dry electrodes and semi-dry electrodes, and is generally made into a shape similar to a hat in physical form. In use, conductive paste, gel and other substances need to be applied, and the electrode cap has requirements for fixing the human head, and once the position does not match, the signal transmission quality will be greatly affected, and the emotion treatment and improvement effect will be discounted.
[0045] In order to avoid the above-mentioned respective shortcomings of the invasive and non-invasive electrode caps, domestic researchers have researched various products for improving and optimizing human brain waves and emotions based on sound-light, and an attention regulation method and system based on binaural beat brain wave audio are adopted. For example, a certain sound-light device for generating binaural beats is disclosed in a utility model patent in China, which includes an audio player and earphones, and achieves the effect of binaural beats by playing existing ordinary tapes, CDs and the like, to realize attention regulation and emotion improvement of users.
[0046] However, the above patents need to modify or add a frequency conversion unit to the existing player to play the existing ordinary magnetic tape, CD, etc. to realize the binaural wave difference effect, the physical separation of each module is low in integration, and the user needs to set and operate the frequency module individually during use. In addition, the patent scheme only uses sound as a simple excitation to adjust the brain wave frequency to optimize the brain emotion, and the effect is limited.
[0047] Therefore, in order to solve the technical defects existing in the above related technology, the utility model provides a variable frequency sound and light brain wave frequency modulator for exciting variable frequency and adjusting brain wave frequency, which avoids the problem of physical damage of invasive opening of the head of the person, solves the problem of the need for conductive paste, gel matching and the requirement for strict one-to-one correspondence between the electrode cap and each point of the head of the person of the traditional head-mounted non-invasive electrode cap, improves the device for generating binaural wave difference in the related technology, enriches the way of brain wave excitation, and can be flexibly used with external sound source and product program. For example, the favorite music, learning materials, and self-growth audio materials can be connected to the program to enhance the effect and improve the pleasant experience.

[0049] Further, the sound and light triggering module further includes a three-way pulse signal generator, which is used to generate three-way synchronous pulse signals according to parameter requirements and output to three spectrum output paths synchronously.
[0050] Based on the above embodiments, it can be understood that the variable frequency sound and light brain wave frequency modulator of the utility model excites and adjusts the brain wave of the head by combining three-way pulse spectrum signals with stereo audio output signals, wherein the signal amplitude range, the waveform of the signal, and the duty cycle of the three-way pulse signal are adjusted by the bottom programming control signal, and the starting frequency, the signal amplitude, and the frequency change step of the stereo audio output signal are adjusted by the bottom programming control signal.
