Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to an audio-based intelligent snoring control method and snoring control device. Background Art

[0002] Snoring is a common phenomenon in daily life, which is mainly caused by the vibration of the upper respiratory tract during sleep. Snoring not only affects others' rest, but also has many harmful effects on one's own health. For example, during snoring, sleep apnea syndrome is a common symptom of snoring, which not only affects the quality of sleep, but in severe cases may cause complications such as hypertension, coronary heart disease, arrhythmia, cerebrovascular disease, cognitive dysfunction, etc.

[0003] In response to the above situation, some anti-snoring products have appeared on the market, such as electronic anti-snoring devices, ear-hanging anti-snoring devices, etc. These anti-snoring products monitor the user's snoring and then make corresponding anti-snoring operations to remind the user to stop snoring. However, these products have corresponding defects. For example, electronic anti-snoring devices usually wake up snorers through operations such as electric shocks, but electric shocks can cause irreversible damage to human health; ear-hanging anti-snoring devices are wearable products. For most ordinary people, wearing this product will seriously hinder their sleep. Summary of the invention

[0004] To solve at least one of the above problems, the present invention proposes an audio-based intelligent snoring control method and device.

[0005] The technical solution of the present invention is: an intelligent snoring prevention method based on audio, comprising the following steps:

[0006] S1, receiving external sounds including snoring based on the sound receiving module, converting them into electrical signals and transmitting them to the offline intelligent voice chip;

[0007] S2. Based on the offline intelligent voice chip, the external sound is compared with the snoring sound in the database. If the external sound includes the snoring sound, the data of the first audio in the database is transmitted to the speaker module through the offline intelligent voice chip through an electrical signal, and the speaker module plays the data of the first audio in the form of sound; the frequency of the first audio is greater than 2000 Hz, the intensity is not greater than 60 decibels, and the duration is not greater than 2 seconds;

[0008] S3, judging whether there is still snoring through the sound receiving module and the offline intelligent voice chip, if there is snoring, repeat S2; if there is no snoring, enter S4;

[0009] S4. Transmitting the data of the second audio in the database to the speaker module through the offline intelligent voice chip, where the second audio is a sleep-aiding audio.

[0010] An implementation manner of the present invention is that the frequency of the external sound that can be received by the sound receiving module is 200-1000 Hz.

[0012] An implementation manner of the present invention is that in S2, the first audio has at least 2 tones.

[0013] An implementation manner of the present invention is that in S2, the first audio is repeatedly played 2 to 5 times.

[0014] An implementation manner of the present invention is that in S4, the sleep-aiding audio is one of white noise, light music and brain wave audio.

[0015] Another object of the present invention is to provide an audio-based intelligent anti-snoring device, comprising:

[0016] A sound receiving module, used for receiving external sounds including snoring;

[0017] A speaker module, used for outputting sound;

[0019] An implementation manner of the present invention is that the sound receiving module can receive external sound with a frequency of 200 to 1000 Hz.

[0020] An implementation manner of the present invention is that the speaker module is a full-range speaker module.

[0021] Beneficial effects: The method and device of the present invention can effectively improve the snoring of snorers and improve the sleep quality of snorers; at the same time, the device is an external device and will not affect the normal sleep of snorers. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Figure 1 Schematic diagram of the structure of the device of Example 2. DETAILED DESCRIPTION

[0023] The specific implementation modes of the present invention will be described clearly and completely below with reference to examples and drawings. Obviously, the described examples are only some embodiments of the present invention, rather than all embodiments.

[0024] In the following examples, unless otherwise specified, the drugs used are conventional commercial products.

[0025] In the following examples, unless otherwise specified, all methods used are routine operations in the art.

[0026] Embodiment 1, an audio-based intelligent snoring prevention method, comprising the following steps:

[0027] S1, receiving external sounds including snoring based on the sound receiving module, converting them into electrical signals and transmitting them to the offline intelligent voice chip;

[0028] In this step, the main task is to collect external sounds. During the collection process, multiple sounds may be collected, such as snoring, talking, etc. These sounds will be received and collected in a unified manner and finally transmitted to the offline intelligent voice chip.

[0029] At the same time, considering the characteristics of snoring, its frequency is mostly between 200 and 500 Hz, and some people's snoring can reach 900 Hz. Therefore, there is no need to collect some external sounds with higher or lower frequencies. Therefore, we limit the frequency of external sounds that the sound receiving module can receive to 200 to 1000 Hz.

[0030] S2. Based on the offline intelligent voice chip, the external sound is compared with the snoring sound in the database. If the external sound includes the snoring sound, the data of the first audio in the database is transmitted to the speaker module through the offline intelligent voice chip through an electrical signal, and the speaker module plays the data of the first audio in the form of sound; the frequency of the first audio is greater than 2000 Hz, the intensity is not greater than 60 decibels, and the duration is not greater than 2 seconds;

[0031] For the offline intelligent voice chip, we choose an existing offline intelligent voice chip in the prior art, such as the CI1102 offline intelligent voice chip of Chengdu Qiying Tailun Technology Co., Ltd., which can perform simple recognition and judgment of voice functions and also has a certain storage capacity. Of course, those skilled in the art can choose other chips with the same function.

[0032] When comparing sounds, snoring has the following characteristics: intermittent, a single snoring sound lasts for 1 to 3 seconds, and the characteristics of multiple snoring sounds (duration, frequency, etc.) are basically the same. Therefore, the existing offline intelligent voice chip can be used to easily identify it.

[0033] After detecting snoring, the offline intelligent voice chip transmits the first audio in the database to the speaker module and plays it, and at the same time limits the frequency of the first audio to be greater than 2000Hz, the intensity to be less than 50 decibels, and the duration to be less than 2s. The reason for such limitations is that it is related to the recognition of sound by the central nervous system after a person falls asleep.

[0034] According to the prior art, it is difficult for a human body to be awakened by its own snoring. This is mainly because after falling asleep, the human central nervous system shields the effect of snoring on the human body. In this case, the human body can usually only be awakened by external sounds. At the same time, according to the inventor's experiments, when a high-frequency sound greater than 2000Hz is used, it is easy to temporarily wake up a sleeping person and put him into a light sleep state. If there is no continued stimulation for a period of time (usually tens of seconds or minutes), the snorer will continue to sleep; but when the snorer enters a light sleep state, he is very likely to turn over and adjust his sleeping position. After adjusting his sleeping position and continuing to fall asleep, his snoring will be reduced or even disappear, thereby achieving the purpose of stopping snoring.

[0035] At the same time, according to a large number of experiments conducted by the inventor, when the sound frequency reaches 2000Hz or above, the sound intensity does not need to be very high. Usually, a high-frequency sound of no more than 60dB can wake up the snorer. When the sound intensity is too high, not only will the snorer be completely awakened and difficult to fall asleep, but it will also wake up other sleepers in the room, which has a greater impact. The duration of the sound should not be too long either. When it lasts too long, it will also wake up the snorer completely and wake up other sleepers in the room.

[0036] In particular, the inventors have found that when the frequency of the first audio is 2000-3000 Hz, the intensity is 30-40 decibels, and the duration is no more than 2 seconds, it can temporarily wake up the snorer without affecting other sleepers in the room.

[0037] At the same time, the inventors also found that, for the first audio, when it has multiple tones, it can better wake up the snorer and requires a shorter time, such as 1 second.

[0038] According to a large number of clinical trials conducted by the inventor, the number of times the first audio is played is usually controlled to be 2 to 5 times. Within this range of times, most snorers can basically be temporarily awakened.

[0039] S3, judging whether there is still snoring through the sound receiving module and the offline intelligent voice chip, if there is snoring, repeat S2; if there is no snoring, enter S4;

[0040] After playing the first audio, we also need to use the sound receiving module to continue to receive external sounds, and use the offline intelligent voice chip to determine whether there is still snoring in the external sound. This is mainly for some snorers who are in deep sleep. During the process of playing the first audio in S2, they are not temporarily awakened. Therefore, if the snorer continues to snore, repeat S2 until the snorer is temporarily awakened. Generally speaking, according to the inventor's clinical trials, the operation of S2 will not be repeated more than 3 times. About 90% of snorers will be temporarily awakened by playing the first audio only once; about 9.5% of snorers will be temporarily awakened by playing the first audio twice; about 0.5% of snorers will be temporarily awakened by playing the first audio three times.

[0041] S4. Transmitting the data of the second audio in the database to the speaker module through the offline intelligent voice chip, where the second audio is a sleep-aiding audio.

[0042] After the snorer is temporarily awakened by the first audio, in order to ensure the sleep of the snorer, it is necessary to quickly hypnotize the snorer to make him fall asleep. Therefore, we also need to transmit the data of the second audio to the speaker module and play it. As for the second audio, it is sleep-aiding music, which can be one of the common white noise, light music and brain wave audio. As for the second audio, its playing time is usually 10 to 30 seconds. According to the inventor's test, the second audio of this length can quickly hypnotize the snorer and make him fall asleep.

[0043] In summary, the embodiments of the present invention establish a detection-temporary awakening-rapid hypnosis method for stopping snoring. When snoring is detected, the snorer is temporarily awakened by a first audio. After the snorer adjusts his sleeping position, he is quickly hypnotized by a second audio, thereby reducing or even preventing snoring.

[0044] Embodiment 2, an audio-based intelligent snoring device, comprising:

[0045] The sound receiving module 2 is used to receive external sounds including snoring; among them, it can receive external sounds with a frequency of 200 to 1000 Hz. This is mainly because the frequency of snoring is mainly concentrated in the range of 200 to 500 Hz, and some are around 800 to 900 Hz. Therefore, taking into full consideration the actual situation, we set its receiving frequency to 200 to 1000 Hz; there are many sound receiving modules 2 that can receive sounds in this frequency range, such as common condenser microphones.

[0046] The speaker module 3 is used to output sound. The speaker module 3 needs to output a first audio with a relatively high frequency and a second audio with a relatively low frequency. Therefore, a full-range speaker is usually selected, which is a prior art.

[0047] The offline intelligent voice chip 1 is provided with a database, which includes snoring, a first audio and a second audio. The sound receiving module 2 and the speaker module 3 are electrically connected to the offline intelligent voice chip 1. The offline intelligent voice chip 1 is a conventional chip in this field and can be purchased from the market. At the same time, in order to give full play to the role of the offline intelligent voice chip, corresponding auxiliary components are also provided, such as a circuit board 4, memory, etc., which are conventional settings in this field and can be purchased from the manufacturer together with the offline intelligent voice chip. Among them, the first audio is limited to a frequency greater than 2000Hz, an intensity of no more than 50 decibels, and a time of no more than 2s. The preferred frequency is 2000-3000Hz and an intensity of 30-40 decibels; the second audio is limited to sleep-aiding music.

[0048] Of course, for the device of this embodiment, due to its simple structure, only three main components are provided, so its power consumption is relatively low. At the same time, for each module, only the sound receiving module 2 and the offline intelligent voice chip 1 need to work for a long time, and the power consumption of these two modules is very low. Therefore, a corresponding built-in power supply can be set, for example, a button battery can be set as its function; an external power supply can also be set, but since the components of this embodiment have low energy consumption, it can be powered by an external USB power supply interface 5.

[0049] At the same time, the device of this embodiment has a simple structure and the size of each component does not need to be made very large. Therefore, in actual use, it can be placed around the snorer, such as at the bottom of the pillow. In this case, the device of this embodiment can only affect the snorer without affecting other people in the room.

[0050] The inventor has developed a device according to Example 2, in which the sound receiving module 2 is a capacitive microphone, the speaker module 3 is a full-frequency speaker, and all offline intelligent voice chips 1 are CI1102 offline intelligent voice chips of Chengdu Qiyingtailun Technology Co., Ltd. Its supporting auxiliary components, such as circuit boards 4 and memory, are also purchased from Chengdu Qiyingtailun Technology Co., Ltd. The power supply used is a USB power supply interface 5, which is powered by an external power supply; at the same time, a shell 6 is provided for protecting the sound receiving module 2, the speaker module 3 and the offline intelligent voice chip 1; the size of the shell 6 of the device is 20mm*20mm*20mm.

[0051] The first audio is excerpts from the first and third chapters of Sibelius's Violin Concerto in D minor, with a duration of 2s and a frequency greater than 2000Hz; the second audio is an excerpt from the second chapter of Sibelius's Violin Concerto in D minor, with a duration of 35s, which is a lyrical section. The second audio also stores alpha brain wave sleep-aiding music.

[0052] 200 snoring patients were selected for testing. All of them had severe snoring problems, and snoring affected their mental state. After using the device of this embodiment for one week, the snoring of 155 snoring patients was significantly improved, and the snoring frequency was greatly reduced; after one month, the snoring of 176 snoring patients was significantly improved, and the snoring frequency was greatly reduced. The sleep quality of 164 snoring patients was significantly improved and their mental state was improved.

[0053] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with the profession can make some changes or modifications to equivalent embodiments of equivalent changes using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the scope of the technical solution of the present invention.
