Description

Electronic snore relieving device
Technical Field
The invention relates to a snore stopper, in particular to an electronic snore stopper capable of being adaptively adjusted.
Background
Snoring is a sound of snoring caused by vibration of uvula (uvula) due to upper airway stenosis during sleep. The tonsil hypertrophy, too large tongue, excessive drinking and the like can cause snoring. Snoring can lead to daytime sleepiness, weakness, inattention, headache, reduced working capacity, and the like. Snoring is an independent risk factor for hypertension, and severe snoring is often accompanied by sleep apnea syndrome.
At present, the snoring treatment method mainly comprises operation treatment, laser treatment and drug treatment, but practice proves that the treatment effects of the methods are not obvious, and the methods can reflect the skin and cause certain harm and side effect to human body after a period of time.
There are three methods for treating snoring currently adopted by the medical community:
1. continuous Positive Airway Pressure (CPAP) by direct filling of air with a respiratory mask;
2. umbelliferae soft palate throat orthography (UPPP) is that the opening cuts off the soft palate and uvula of throat, make the blocking effect of tongue reduce;
3. the dental appliance is used to bite the chin into the forward extended position for the chin lead (MAD). Among them, CPAP has the most obvious effect of improving respiratory system, but many people cannot tolerate the breathing mask covered on the face when sleeping, and carry an inflator when traveling outside; UPPP appears to be permanent once a day, but many studies report improvement levels of only fifty percent and may relapse; although the improvement of using MAD can reach seventy percent, it is uncomfortable to bite on MAD while sleeping, and if the shape and size of MAD are not designed for individual, it can also cause gum soreness and problems with the chin joints and muscles.
The electronic snore stopper has the advantages that the physical treatment intensity of the intelligent snore recognition function automatic regulation chip to the appointed acupuncture points can promote the change of the tension of the overhanging muscles of the patient's larynx, so that the originally blocked respiratory tract is restored to be smooth, the most comfortable respiratory effect is achieved, and the effect takes place almost immediately.
Electronic snore stopping devices are mainly divided into: wrist and ear wearing.
The wrist snore stopping device is based on the principle that when the biological micro detector in the body detects the snore of the user exceeding 65 dB for three times, the body can output a weak electric pulse stimulus with the length of 4 seconds to the skin of the user, and the stimulus can lead the user to generate the following reflex behaviors so as to achieve the aim of reducing or inhibiting the snore. The technology can be influenced by sounds other than snores, the circuit lacks differentiation of the snores and noise, for example, when the external noise and the dream are present, misoperation can be avoided, false alarm exists, the circuit is easy to cause false triggering, an electric stimulus is generated for a user, a pulse voltage stimulates the patient to feel that the patient has acupuncture pain, the sleeping quality of the patient can be influenced, the user is forced to wake up from the deep sleep, the snores are small but the sleeping quality is reduced; when the snore detector is worn on the hand, the snore detector may be affected by shielding by a person or other objects, so that the snore detector is inaccurate.
The ear-wearing snore relieving device detects whether snoring occurs by combining bone conduction technology, sound discrimination and the like, and adopts the pure physical intervention principle of micro sound and micro vibration to realize snoring relieving, and has the defects that the sleep is disturbed in a vibration mode, so that the sleep quality is reduced; in-ear interference with the user's sleep hearing.

Detailed Description
The objects, technical solutions and advantages of the embodiments of the present invention will be more apparent, and the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Referring to fig. 1-2, the electronic snore relieving device provided in the embodiment of the present invention is worn on a jawbone portion of a face, and includes an audio sampler, a central controller, an audio signal transmitter, an adaptive regulator, control buttons, a display screen, a memory, and a power supply. The central controller is respectively connected with the audio signal gain amplifier, the self-adaptive regulator, the audio signal transmitter, the control button, the display screen, the memory and the power supply. The audio sampler and the audio signal transmitter are both positioned in the machine body proximate the paraoto-jawbone. The audio frequency sampler is used for collecting sound signals and converting the collected sound signals into electric signals; an audio signal gain amplifier for amplifying the electrical signal; the central controller comprises an audio frequency identification module and a white noise generation module, wherein the audio frequency identification module is used for identifying the amplified electric signals and determining first snore; the white noise generation module is used for determining white noise according to the first snore; an audio signal transmitter for converting a white noise signal into a vibration signal and transmitting the vibration signal; and the self-adaptive regulator is used for regulating the white noise according to the sound signal acquired again after the vibration signal is sent. White noise is a noise with a uniform and continuous spectrum, with the effect of "masking" other sounds, and white noise through programming has the effect of masking other sounds to aid sleep.
In one example, the audio sampler comprises a bone conduction collector and the audio signal transmitter comprises a bone conduction transmitter. Bone conduction refers to the transmission of sound waves through vibrations of the skull, jaw, etc., for example, bone conduction transmitters transmit sound waves through vibrations of the skull, jaw, etc. to the inner ear. In addition, the audio sampler may employ a conventional microphone and the audio signal transmitter may employ a conventional speaker.
In one example, the method for identifying the amplified electric signal and determining the first snore specifically includes frequency identification of the amplified electric signal, wherein the sound frequency of a person is 85Hz-200Hz, if the collected sound frequency does not belong to the range, the central controller considers that the sound frequency is not sound of the person, the central controller judges that the sound frequency is false triggering, the audio data is abandoned, if the sound frequency belongs to the range, the audio data is judged to be possibly snore, and the sound frequency of the audio data exceeding the range of 85Hz-200Hz is filtered, so that environmental noise is filtered. Because the snore is generally regular audio, and other sounds are irregular sounds, audio data which is possibly snore can be clipped and screened, and the clipped and screened result is matched with a sample library, so that the first snore can be effectively analyzed. In addition, a neural network model can be trained, and the first snore can be directly identified through the trained neural network model.
In one example, according to the snore, the specific method for determining white noise comprises the following steps: identifying a lowest frequency and a highest frequency of the snore; and determining white noise according to the lowest tone frequency, the highest tone frequency and preset audio elements.
The preset audio elements are audio clips which assist sleep or calm people, such as clips of classical music, or running water sounds and insect sounds. Because the high frequency signal is too high in stimulation to the brain, the person is in an excited state, so that the person is difficult to fall asleep. On the contrary, the low-frequency signal has lower sound frequency, so that the brain is immersed, and the hypnotic effect is achieved, and people can fall asleep easily. In the state of falling asleep, the low-frequency sound does not interfere with sleep, but rather, the low-frequency sound is combined with brain wave scanning periods of the cerebral cortex in a static state, namely, in a state that the brain does not think, so that resonance is formed, the brain wave frequency value is stable, and the sleep quality is high. Conversely, if the noise is around, the audio frequency is disturbed and is higher than the scanning frequency of brain waves in the sleeping state, the brain wave frequency is clearly disturbed, and once the frequency exceeds the normal frequency range, the brain is restored to the excited state, so that the person is in a sleep-like non-sleeping state, and the sleeping quality is greatly reduced. By utilizing the principle, white noise is determined according to the lowest tone frequency, the highest tone frequency and preset audio elements, and a high-frequency signal in the synthesized white noise can enable a person to be in a proper excited state, so that snoring is not generated.
In one example, determining white noise from the lowest audio frequency, the highest audio frequency, and the other audio elements that are preset includes: setting the lowest frequency as the starting frequency of the white noise; setting the highest sound frequency as a cut-off frequency of the white noise; and determining white noise according to the starting frequency of the white noise, the cut-off frequency of the white noise and the preset audio element. Further, it is also possible to set the lowest sound frequency multiplied by a predetermined coefficient as the start frequency of the white noise; multiplying the highest sound frequency by a predetermined coefficient to set the highest sound frequency as the cut-off frequency of the white noise; and determining white noise according to the starting frequency of the white noise, the cut-off frequency of the white noise and the preset audio element.
In one example, the adjusting the white noise based on the re-acquired sound signal includes: identifying a second snore from the re-acquired sound signal; judging the volume of the second snore and the first snore; and when the second snore volume is smaller than the first snore volume, reducing the cut-off frequency of the white noise. The method comprises the steps that a high-frequency signal is added to white noise audio synthesized when a user snores, so that the sleeping depth of the user is temporarily reduced to a certain extent, the throat muscle relaxed by the user is restored to a certain degree, the snoring is stopped, when the user hears a section of white noise to relieve the snoring, a sound signal can be collected again, a second snore is identified, if the snoring is reduced, the proportion of the high-frequency signal in the white noise is slowly reduced, the sleeping quality of the user is improved, the high-frequency signal can be reduced until the snoring of the user is enlarged, and the snoring stopping time of the user is prolonged for the maximum time. After self-adaptive adjustment for a period of time, white noise which is most suitable for a user can be synthesized, so that snore can be relieved, and the sleeping quality of the user can be ensured to the greatest extent.
In one example, the adjusting the white noise according to the re-acquired sound signal further includes: and when the second snore volume is smaller than the first snore volume, reducing the starting frequency of the white noise. By reducing the starting frequency of the white noise, the frequency of the low frequency signal can be increased, and the proportion of the high frequency signal can be reduced, thereby improving the sleeping quality of the user.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
