The long-term sleep deficiency also causes irreversible damage to the brain, and can cause mental disorders such as anxiety, depression and the like. Researches show that the insomnia can also accelerate the pathogenesis process of the Alzheimer disease; sleep disorders can lead to elevated levels of soluble beta amyloid in the body, which folds and forms sticky plaques, killing brain cells, and impeding information processing. Whereas amyloid deposition in brain tissue was first considered a preclinical symptom of alzheimer's disease, occurring earlier than the typical symptoms. Some studies have found that chronic insomnia is associated with the formation of amyloid plaques in brain tissue; it has also been partially discovered that tau-tandle protein accumulation may be a signal for the development of Alzheimer's symptoms.

Detailed Description

The best mode for carrying out the present invention will be described in detail with reference to the accompanying drawings, wherein the detailed description is for the purpose of illustrating the invention in detail, and is not to be construed as limiting the invention, as various changes and modifications can be made therein without departing from the spirit and scope thereof, which are intended to be encompassed within the appended claims.

Brain electrical activity exists in the brain, and brain waves (EEG) are a method for recording brain activity by using electrophysiological indexes, are formed by summing postsynaptic potentials synchronously generated by a large number of neurons during brain activity, record electric wave changes during brain activity, and are the overall reflection of the electrophysiological activity of brain nerve cells on the surface of a cerebral cortex or scalp.

Typical waveforms for various types of brain waves are shown in fig. 1, in which Alpha waves (Alpha waves) have a typical frequency of 8-13Hz, Beta waves (Beta waves) have a typical frequency of 14-30Hz, Gamma waves (Gamma waves) have a typical frequency of 30-80Hz, Delta waves (Delta waves) have a typical frequency of 1-3Hz, and Theta waves (Theta waves) have a typical frequency of 4-7 Hz. Generally, it is considered that a delta wave represents sleep, fatigue and a subconscious state, a theta wave represents drowsiness, deep relaxation and a subconscious state, an alpha wave represents waking and quiet and is the best state for learning and thinking, a beta wave represents thinking activity, busy and tension, a gamma wave represents high-grade cognitive activity, and the excitability of neurons is increased.

The invention provides a low-frequency acousto-optic sleep assisting device, which comprises one or more light emitting modules 110, a light adjusting module 115, a light frequency filtering module 120, one or more sound generating modules 125, a sound adjusting module 130, a sound frequency filtering module 135, a main control module 140 and a data file storage 145, as shown in fig. 2.

The light emitting module 110 is preferably an LED light source, which may also be an OLED, fluorescent light source, incandescent light source, laser, etc., for generating a visual signal, such as a light pulse, a flash of light, etc., according to predetermined parameters. The wavelength of the optical signal generated by the light emitting module 110 is preferably a visible light range wavelength of 380nm to 750nm, and may be monochromatic light or a multi-color mixed light, and preferably a 550nm wavelength optical signal most sensitive to human eyes is adopted. The predetermined parameters for instructing the generation of the optical pulses may include the frequency or wavelength of the optical wave, the intensity, the pulse duration, a sequence of frequency pulses, a pulse sequence interval, or the duration of a pulse sequence (e.g., the number of pulses in a pulse train or the duration of a pulse train, a predetermined frequency).

The light emitting module 110 generates a desired light visual signal of a particular waveform under control of predetermined parameters, typically as shown in fig. 3, which is a sequence of light pulses actuated in waveform, the light emitting module 110 being continuously rapidly turned on and off to form a train of light fields 220 of continuously varying amplitude whose energy, after sliding averaging over a time domain, forms a normally distributed-like light intensity signal waveform as indicated at 225. The intensity, color, pulse frequency, etc. of the light signal may vary over time. In fig. 3, the horizontal axis represents time, and the vertical axis represents relative light intensity.

The light conditioning module 115 is used to increase or decrease the relative ratio between the light visual signal produced by the light emitting module 110 and the ambient light level. The light adjusting module 115 can detect the intensity level of the ambient light near or around the user and adaptively adjust the light intensity signal emitted by the light emitting module 110 according to the working intensity set by the user, so as to avoid insufficient optical stimulation and discomfort of the user.

The optical frequency filtering module 120 is used for filtering the optical excitation signal or the optical driving signal generated by the optical adjusting module 115 to filter out undesired or unwanted frequency signals. For example, when the frequency of the brain waves produced by the desired stimulus is 40Hz, signals less than 20Hz or greater than 80Hz will interfere with the generation of 40Hz brain waves, and therefore such undesirable signals need to be filtered out.

The sound generation module 125 is configured to generate a sound signal according to a predetermined parameter, such as a sound pulse, a sound frequency sweep, a flutter, a howling, a chirp, and the like, preferably a two-tone beat or a two-tone pulse modulated by a periodic carrier frequency, where the predetermined parameter includes a frequency, a sound intensity, a parameter of a sound pulse sequence, a modulation mode of the sound, and the like. Fig. 4 shows a schematic diagram of a two-tone beat signal synthesized from an offset signal and a carrier signal, when the auditory cortex of the brain perceives two stationary tones of similar sound intensity (e.g., the upper two waveforms in fig. 4) at different frequencies, the brain superimposes the two sounds so that the sound of the resultant waveform (e.g., the lower waveform in fig. 4) is perceived and heard after the two are added. Since the two monophonic waveforms have a deviation in frequency, the parts of the two waveforms are superimposed and partially cancelled out so that their envelopes form the pulses 1130 separated by the balance 1125, and the brain generates the corresponding brain waves by sensing the reverberation of the two different waveforms. The sound module 125 may also directly obtain a bi-sound beat or a bi-sound pulse similar to that shown in fig. 4 by using a ppt (pitch panning technique) technology, or directly generate the required bi-sound beat or the bi-sound pulse by playing back audio data, audio files, and the like. And meanwhile, a stereo technology can be adopted to further generate a reverberation effect.

The sound conditioning module 130 is used to increase or decrease the relative ratio between the sound signal generated by the sound generation module 125 and the ambient sound level. The sound adjusting module 130 can detect the intensity level of the environmental sound near or around the user and adaptively adjust the sound intensity signal emitted by the sound emitting module 125 according to the working intensity set by the user, so as to avoid insufficient acoustic stimulation and discomfort of the user.

The acoustic frequency filtering module 135 is used to filter the acoustic excitation signal or the acoustic driving signal generated by the acoustic conditioning module 130 to remove undesired or unwanted frequency signals. For example, when the frequency of the brain waves produced by the desired stimulus is 40Hz, signals less than 20Hz or greater than 80Hz will interfere with the generation of 40Hz brain waves, and therefore such undesirable signals need to be filtered out.

In order to obtain appropriate optical and acoustic excitation signals, the invention can adopt the scheme shown in fig. 5 to test the user, so that the acousto-optic signal emitted by the low-frequency acousto-optic sleep assisting device provided by the invention can accurately and efficiently excite the gamma wave in the brain wave of the user.

The optical signal and/or the acoustic signal 3615 generated by the light emitting module 110 and/or the sound emitting module 125 are adjusted by the frequency, waveform and variation pattern of the gamma waves in the brain electrical activity signal 3620, so that the most suitable optical signal and/or acoustic signal 3615 for exciting the gamma wave brain electrical waves of the user 3605 is established and stored in the data archive 145. The main control module 140 reads the required optical signal and acoustic signal excitation mode from the data file storage 145 according to the personal data of the user and the setting of the user, and drives the light emitting module 110 and/or the sound emitting module 125 to generate the optical signal and/or the acoustic signal 3615, so as to stimulate the user 3605 to generate the corresponding gamma wave brain waves.

One or more of the frequency, waveform and variation pattern of the gamma wave brain wave stimulated by the optical signal generated by the light emitting module 110 and one or more of the frequency, waveform and variation pattern of the gamma wave brain wave stimulated by the acoustic signal generated by the sound generating module can be the same or different, if the two are the same, the effect of mutual superposition of the two is utilized, and if the two are different, different regulation effects on the nervous system of the user can be realized through different gamma wave brain waves so as to realize mutual synergy.
