Description

[Technical Field]

[0001] This invention relates to a sound generating device that utilizes various biological sounds of humans and other organisms to support sound sleep, health management, or the formation of emotional bonds with subjects, and further relates to a sound generation technology that utilizes the potential fluctuation signals of plants to generate sound, promoting emotional stability and communal resonance between the user and the natural environment. [Background technology]

[0002] Research has shown that listening to the heartbeat and breathing sounds of the mother is generally effective in stabilizing the emotional well-being of children and infants. From this perspective, the following prior art has been proposed. In recent years, it has been discovered that minute electrical potential fluctuations occur on the leaf surface and roots of plants, and that these fluctuations occur periodically or aperiodically in response to external stimuli such as light, moisture, contact, and temperature. This plant potential fluctuation is a type of life activity, and it has been reported to have rhythmic and 1 / f fluctuation characteristics, similar to the heartbeat and breathing of humans and animals. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2018-68962 Summary of the Invention [Problem to be solved by the invention]

[0004] This prior art technology is comprised of a sensor, a sleep aid device, and a speaker, and is designed to improve sleep by playing sound content with tempos that correspond to the mother's biological rhythm. The sounds in this case include recordings of sounds from inside the womb, noise-type sounds, music box sounds, and synthesized sounds of these.

[0005] However, while such conventional technology only proposes improving sleep by having infants listen to the mother's vital sounds, it would be preferable if it could be used more broadly to reduce stress, support sound sleep, foster a sense of security and intimacy, and strengthen emotional ties not only between mother and child, but also between other family members, lovers, pregnant women, nursing mothers, the elderly, or those receiving care.

[0006] On the other hand, hearing-impaired people and the elderly may have limited hearing function and may have difficulty perceiving sound. However, in recent years, it has been reported that mechanoreceptors in the skin (Meissner's corpuscles, Raffini endings, etc.) respond to low-frequency vibrations of 20 Hz or less, resulting in pressure sensations, warmth sensations, and emotional stability.

[0007] In addition, extremely low frequency stimulation via bone conduction or fascial conduction induces a sense of resonance throughout the body, making it possible to sense sound through touch, a sense other than hearing.

[0008] The present invention was made in consideration of the above circumstances, and aims to provide an acoustic generating device that can strengthen emotional ties and bonds and increase emotional stability between people who have close relationships, such as mothers, fathers and infants, other family members, lovers, friends, etc., and that can also enable users with limited hearing function, such as the hearing impaired, the elderly, and infants, to experience sound in three dimensions through tactile sensations such as skin, fascia, and bone conduction.

[Effects of the Invention]

[0019] This device can form emotional bonds in relationships that are core to social communities, such as parent-child relationships, including mother-child relationships, and the entire family, including pet animals. It can also be used not only in family relationships but also more broadly to reduce stress, support sound sleep, foster a sense of security and intimacy, and strengthen emotional ties in relationships with relatives, non-blood-related family members, lovers, friends, and even pregnant women, the elderly, or those receiving care.

[0022] By using plant potential information to generate sound, users can simultaneously receive both the rhythm of the natural environment and their biological rhythms, promoting deep relaxation, sound sleep, and emotional stability. Furthermore, by sharing audio content that combines biological sound information and plant potential information among multiple users, it is possible to promote the formation of "bonds" as an extended community that includes nature.

[0024] Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS.

[0025] In this embodiment shown in FIG. 1, the sound generating device 10 is configured to be able to transmit and receive various information to and from user terminals 11 owned by multiple users and medical institution terminals 12 owned by a medical institution via a network 13, and the sound generating device 10 functions as a component of a body sound information utilization system 1 composed of the sound generating device 10, the user terminals 11, and the medical institution terminals 12.

[0026] In this embodiment, the body sound signal shaping unit 15, synthesis means 17, sharing unit 20, communication unit 21, and control unit 22 that constitute the sound generating device 10 shown in FIG. 2 are configured, for example, as software stored in a single cloud server, and are configured to acquire various types of body sound information collected by each user terminal 11 through information transmission between the device and each user terminal 11, transmit relaxing voice information to each user terminal 11 after performing shaping and synthesis processing described below on the body sound information, and also share the information between the user terminals, and, if necessary, transmit cardiac disease information extracted from the body sound information to the medical institution terminal 12.

[0027] The biological sound signal shaping unit 15, the disease detection support unit 19, the synthesis means 17, the control unit 22, the communication unit 21, and the sharing unit 20 that constitute the sound generating device 10 are not limited to this specific example, and may be configured to be installed individually as application software on each terminal and used, for example.

[0028] The configurations of the sound generating device 10, the user terminal 11, and the medical institution terminal 12 will be described below. The sound generating device 10 shown in FIG. 2 includes a sound collection unit 14 that collects body sound information, a body sound signal shaping unit 15 that shapes the audio signal constituting the body sound information collected by the sound collection unit 14 into a 1 / f fluctuation characteristic based on the time fluctuation characteristic, and an output means 16 that transmits the audio information shaped by the body sound signal shaping unit 15 to a target user.

[0029] In this embodiment, "body sound information" refers to the voices, heart sounds, breathing sounds, blood flow sounds, etc. of the user's mother, father, relatives, lovers, friends, acquaintances, and other people who are blood relatives or close acquaintances of the user, as well as animals, birds, etc. kept by the user, and the "user" refers to, for example, the mother, the father's children, infants, elderly people who are blood relatives of the relatives, people who need care, or the owners of the kept animals.

[0030] The "body sound information" in this embodiment may include weak potential fluctuation signals observed on the leaf surface and roots of plants (hereinafter referred to as plant potential information) in addition to the vital sounds of humans and animals. "Plant potential information" responds to light irradiation, water supply, temperature changes, contact stimuli, etc., and shows periodic or aperiodic changes, exhibiting rhythmic and 1 / f fluctuation characteristics based on life activity.

[0031] The sound collection unit 14 may be, for example, a microphone installed in a smartphone constituting each user terminal 11 or a small microphone used in a wearable device. The body sound signal shaping unit 15 is configured to shape the body sound signals constituting various body sound information collected by the sound collection unit 14 into 1 / f fluctuation characteristics based on the time fluctuation characteristics. "1 / f fluctuation" refers to a fluctuation in which the power (spectral density) is inversely proportional to the frequency f. So-called "pink noise" is noise with 1 / f fluctuation, also known as 1 / f noise, and examples of this include the interval between human heartbeats, the swaying of a train, the sound of a babbling brook, and the swaying of hair.

[0032] Research has shown that when humans listen to 1 / f fluctuation sounds, their brains enter an alpha wave state, resulting in a relaxation effect. Pink noise is also said to be particularly effective for deep sleep and memory support. In other words, pink noise synchronized with the brain's slow wave (SWA) enables deep sleep, and is also said to be particularly effective in consolidating memories in the elderly. The sound generating device 10 shown in FIG. 2 also includes a disease detection support unit 19 that notifies the user terminal 11 and / or medical institution terminal 12 of the user's cardiac disease information when an abnormality is detected based on the cardiac disease index information. That is, as shown in FIG. 2, the biological sound signal shaping unit 15 is configured to extract cardiac disease index information, which is an index of cardiac disease including heart rate, heart rate variability, arrhythmia, and cardiac murmur, from biological sound information, and when an abnormality of the user is detected based on the cardiac disease index information, extract the cardiac disease information and transmit it to the medical institution terminal 12 via the communication unit 21 described later, to notify the medical institution of the possibility of cardiac disease in the user, thereby enabling prompt medical treatment for the user.

[0033] The plant potential shaping unit analyzes the time fluctuation characteristics of the plant potential information, shapes it into 1 / f fluctuation characteristics or fluctuation characteristics that match the user's emotional state, and can synthesize the shaped plant potential information with heart sounds, breathing sounds, voice sounds, external environmental sounds, etc.

[0034] The biological sound signal shaping unit 15 and the plant electric potential shaping unit may be configured to use an AI algorithm to comprehensively analyze the user's input, usage status, psychological indicators, biorhythms, and feature quantities of plant electric potential fluctuations, and automatically set optimal sound generation parameters.

[0035] Therefore, the sound reproducing device 10 in the biological sound information utilization system 1 according to this embodiment not only provides mental stability for the user, stabilizes emotional relationships between mother and child, family members, and friends, and supports development, but also more proactively transmits information to the medical institution that is the user in this embodiment if the user develops a heart disease, enabling the user to visit a medical institution quickly and effectively.

[0036] The sound generating device 10 according to this embodiment also has a synthesis means 17 for synthesizing sound for sound sleep or lullaby sound with shaped body sound information (for example, if the user is a child, the heart sound of the mother, shaped to have 1 / f fluctuation characteristics). The synthesis means 17 can also synthesize sound based on external environment information related to the external environment. That is, the "external environment information" is configured so that information related to environmental sounds around the user during use can be further synthesized with body sound information. In this case, the "external environment information" corresponds to, for example, the following 1 / f fluctuation noises, such as the swaying of a train or the murmuring of a stream.

[0037] As shown in FIG. 2, the sound generating device 10 also has an output means 16 . The output means 16 is configured as an "audio transmission means" and outputs to the user audio information created by shaping and synthesizing biological sounds such as heart sounds and blood flow sounds acquired by the sound collection unit 14. The audio transmission means may be, for example, a speaker, earphones, etc. equipped in each user terminal 11. The same applies to the speaker and earphones in the medical institution terminal 12.

[0038] 2 also includes an aroma generating unit 18 that generates an aroma that induces sound sleep or a sense of security in the user. The aroma generating unit 18 may be configured to diffuse the aroma of a spice, such as an herb, that has a calming and relaxing effect. When the fragrance generating unit 18 is activated, the user can obtain a relaxing effect not only through their hearing through sounds, etc., but also through their sense of smell, thereby providing the user with a comprehensive sleep-inducing effect, a sense of security, and a relaxed state.

[0039] Furthermore, in the sound generating device according to this embodiment, the biosound information includes low-frequency vibration sounds that include frequencies of 20 Hz or less. In this case, the biological sound signal shaping unit 15 is configured as a “low-frequency shaping unit.” The output means 16 is configured as a “low-frequency vibration transmission device,” and is preferably a wearable device that includes, for example, a vibration generating unit including a diaphragm that can transmit vibrations to the body and can transmit vibrations directly to the user’s body. In this case, the vibration generating unit can be configured to include a control unit with a correction function that can analyze and extract low-frequency vibrations from the acquired biological sound information and create wave generation parameters, a diaphragm made of wood, resin, metal or a composite material of these, and an actuator that is operated by the control unit and drives the diaphragm, so as to resonate with the low-frequency vibrations and generate sympathetic vibrations using the diaphragm. It is more effective if the control unit has a learning function using machine learning, for example, deep learning, with teacher data. When using deep learning functions in this way, it becomes possible to process large amounts of voice data quickly, so for example, in a specific large group of people, it is possible to extract and generate low-frequency vibration data that can resonate with the members of the group, and by identifying and using the low-frequency vibration that is the optimal index common to the members of the group, it is possible to create a comfortable sense of unity in the group. Therefore, based on this embodiment, it is also possible to further develop it into a community vibration evaluation system for a specific group.

[0040] The "low frequency shaping unit" is configured to be able to shape a band including low frequencies in the body sound information of each of a plurality of users into 1 / f fluctuation characteristics. The sound generating device 10 according to the embodiment not only collects voice sounds, heart sounds, blood flow sounds, etc., but also collects the biological signals themselves derived from the life activities of the user's parents, family, friends, etc., analyzes and extracts low-frequency components below 20 Hz, and transmits vibrations related to these low-frequency components to the user. In this case, the biological sound information is not voice sounds but vibrations themselves, so even if the hearing function is limited, such as for hearing-impaired people, the elderly, or infants, sound information that contains vibrations, for example, sound information that has a relaxing effect, can be transmitted to the user via skin, fascia, and bone conduction. Therefore, by transmitting to the user low-frequency components extracted from vital signals (heartbeats, breathing sounds) and even environmental sounds and subjecting them to 1 / f shaping, and allowing the user to experience sensations of warmth and pressure, emotional stability can be achieved. As a result, just as with the above-mentioned voice sounds, it is possible to contribute to strengthening the so-called "bonds" in human relationships that form the core of social communities, such as those between parents, family, and friends.

[0041] The sound generating device 10 shown in FIG. 2 also includes a sharing unit 20 that stores body sound information and enables the body sound information to be shared among user terminals 11 owned by multiple users. In particular, when users (e.g., spouses, lovers, parents and children, friends, etc.) are separated by distance, the body sound information can be reproduced on each user terminal 11. It has been confirmed that the heartbeats and breathing of lovers and family members are synchronized. As a result, even when people are separated by distance or time, by sharing vital sound information (e.g., heart sounds), a pseudo-synchronization of heart sounds occurs, which results in a sense of security, intimacy, and a deeper emotional bond.

[0042] By sharing plant potential information on multiple user devices and playing it simultaneously among participants, the plant-derived fluctuations and each user's biological sound fluctuations complement each other, creating a sense of psychological stability, emotional synchronization, or unity as a community mediated by the natural environment.

[0043] The sound generating device 10 shown in FIG. 2 constitutes a body sound information utilization system 1 as shown in FIG. 1, and is equipped with a communication unit 21 and a control unit 22 that can transmit various information such as body sound information to a plurality of other user terminals 11 and a medical institution terminal 12 via a network 13, and can receive various information from the terminals 11 and 12. The control unit 22 controls the operation of the above-mentioned functional units 14 to 21, and the communication unit 21 controls the communication of information based on a communication processing control procedure by the control unit 22, using an appropriate communication protocol such as TCP / IP, HTTP, or FTP.

[0044] In this embodiment, the user terminal 11 shown in FIGS. 1 and 3 includes a communication unit 23 capable of transmitting and receiving various types of information to and from the sound generation device 10 via the network 13.

[0045] The user terminal 11 shown in FIG. 3 also includes a display unit 24 that displays various screens for operating the user terminal 11 and displays various pieces of information received from the sound production device 10. 3 includes an input unit 25 that enables a user to perform operations and input information, and an output unit 26 that can output audio information transmitted from the sound generating device 10 via the network 13. The user terminal 11 also includes a storage unit 27 that stores various types of information, and a control unit 28 that controls the above-mentioned functional units 23 to 27.

[0046] 4 includes a communication unit 29, a display unit 30, an input unit 31, a storage unit 32, a diagnostic information generation unit 33, and a control unit 34. The communication unit 29, the display unit 30, the input unit 31, the storage unit 32, and the control unit 34 have the same configuration as the communication unit 23, the display unit 24, the input unit 25, the storage unit 27, and the control unit 28 of the user terminal 11, and therefore detailed description thereof will be omitted.

[0047] The diagnostic information generating unit 33 generates, as diagnostic information, the cardiac disease information detected and extracted by the sound generating device 10 and transmitted via the network 13. The diagnostic information generating unit 33 is configured to be able to notify the user terminal 11 of the diagnostic information via the network 13.

[0048] According to this embodiment, it is possible to form emotional bonds within communities such as mothers and children, fathers and children, pregnant women, and other family members, and more broadly, to reduce stress, support sound sleep, foster a sense of security and intimacy, and strengthen emotional ties among close human relationships that are not related by blood, such as between lovers, elderly people, or people receiving care. For example, in this embodiment, when maternal sounds (mother's voice and heartbeat) are used with an infant as the user, it is very effective in stabilizing the infant's autonomic nervous system, and as a result, it is possible to contribute to supporting the development and growth of infants and children.

[0049] In other words, it has been made clear in the "NICU Study" (a study of newborns, families, nurses, and the entire medical system in neonatal intensive care units) that listening to the mother's heartbeat stabilizes an infant's heartbeat, stops them from crying, and enables them to fall asleep. It has also been made clear that listening to the mother's voice and heartbeat strengthens auditory-cutaneous activity, contributing to the promotion of development. It has also been found that the mother's voice and lullabies stabilize the physiological indicators of premature babies and have a calming and analgesic effect.

[0050] Furthermore, from the perspective of forming "bonds" in social relationships, the phenomenon of heartbeats and breathing synchronizing and syncing has been observed between lovers and family members, and it has been found that even when people are far apart, they can experience a sense of security and pseudo-synchronization by playing the other person's heartbeat.

[0051] Therefore, the sound generating device of this embodiment is primarily effective between mother and child, but can also be effectively used to strengthen relationships, or form so-called "bonds," with family, relatives, friends, and other relationships that make up the social community, other than the mother-child relationship.

[0052] Furthermore, according to this embodiment, users with limited hearing function, such as the hearing impaired, the elderly, and infants, can experience sound in three dimensions through tactile sensations such as skin, fascia, and bone conduction. This allows even the hearing impaired, the elderly, and even infants to share the low-frequency resonance interval, thereby strengthening and promoting emotional ties. Furthermore, particularly in mother-child relationships, when infants and children hear their mother's voice or lullabies sung by her mother, physiological indicators improve, a calming effect is achieved, and even if pain is caused by some kind of illness, a pain-relieving effect can be obtained.

[0053] The configurations described in the above embodiments can be modified as appropriate within the scope of the present invention, and are not limited to the configurations of the above embodiments. For example, the sound generating device 10 according to the present embodiment may be built into an article used when sleeping, such as a body pillow or a doll, so that the user can enjoy voice sounds or low-frequency vibrations while sleeping. In such a case, the user's relaxation effect while sleeping can be enhanced, resulting in a sound sleep and providing the user with a comfortable life. [Explanation of symbols]
