[0001] The present invention relates to a system and method for easily outputting inaudible low-frequency vibrations (vibrations that cannot be recognized as sound by the human ear because the frequency is 20 Hz or less. Hereinafter, referred to as "ultra-low-frequency vibrations") from a mobile terminal or the like possessed by a user.

Background Art

[0002] Research results showing that ultra-low-frequency vibrations have a positive impact on the human mind and body have been published. There is also a theory that ultra-low-frequency vibrations can prevent the deterioration of dementia and delay the transition of people at risk of dementia to full-blown dementia. Some researchers have installed a device that generates ultra-low-frequency vibrations in a corner of an elderly health facility to investigate its effects on dementia, and it is said that significant effects have been observed. As the number of elderly people increases, the number of dementia patients also increases. The number of centenarians in 2023 is said to be more than 95,000. Despite the increase in the number of long-lived people, spending old age troubled by dementia is by no means happy. Recently, news came out that a drug for Alzheimer's disease has been officially approved, but this drug is not applicable to patients with advanced symptoms and is expensive. Then, until an effective drug for dementia becomes widely available at an affordable price, wouldn't it be meaningful to utilize ultra-low-frequency vibrations, which are said to be effective?

Summary of the Invention

Problems to be Solved by the Invention

[0004] Even if ultra-low frequency vibrations have some effect on the elderly, exposure to ultra-low frequency vibrations in daily life is not yet common at the time of filing of this invention (January 2025). Therefore, the objective of this invention is to provide such opportunities in an easily accessible way. Incidentally, mobile devices, especially smartphones, are being used not only for calls, emails, social media, internet searches, and video viewing, but also for unprecedented purposes such as receiving low-frequency signals from remote low-frequency therapy devices (Patent Document 1) and sending signals from mobile phones to massage devices (Patent Document 2). In this way, mobile devices are becoming usable for therapeutic purposes and other uses beyond their conventional applications. Therefore, the present invention aims to easily generate and output ultra-low-frequency vibrations using information devices such as smartphones, without the need for dedicated equipment. [Means for solving the problem]

[0005] In order to solve the aforementioned problems, The information devices that users use The system is characterized by comprising: means for storing or receiving ultra-low frequency vibration data from an external source; ultra-low frequency vibration output means capable of automatically outputting ultra-low frequency vibrations from an audio playback means when the power is turned on; data fusion means for generating fused sound source data by superimposing ultra-low frequency vibration data on audio data in real time when audio data is played back; and fused sound source data output means for outputting the fused sound source data from the audio playback means. However, the system may be configured such that the server generates the fused sound source data, and the information device receives it. Furthermore, since ultra-low frequency vibration data is essentially transmitted continuously, it is appropriate to pre-record it as data within information devices from the perspective of communication load and other factors. However, since there may be some who wish to be exposed to the ultra-low frequency vibrations generated at various power spots, it is desirable to leave room for external reception at the user's request.

[0006] Information devices include smartphones, tablet devices, and personal computers (PCs). These days, it's commonplace for elderly people to own and be proficient in using information devices, especially smartphones. Even without specialized equipment, simply carrying a smartphone or other information device allows for easy exposure to ultra-low frequency vibrations anytime, anywhere. While internet searches and email sending / receiving are typically silent, receiving these ultra-low frequency vibrations unknowingly may provide a potential dementia prevention effect.

[0007] Infrasound vibrations are not simply defined as being below 20Hz; they must satisfy at least the following two conditions. Firstly, the vibrations must be extracted from non-electronically generated vibration data (meaning they are not generated electronically, i.e., vibrations that do not exist in nature, but are not generated by a predetermined algorithm). For example, they must be vibration data that actually exists in nature, or vibration data obtained by extracting vibrations of approximately 10-20 Hz from musical data produced by playing musical instruments. The reason why non-electronically generated ultra-low frequency vibrations, generally in the 10-20 Hz range, are effective is currently unknown. However, while clarifying the reason will be a future task, it seems certain that they have a positive effect on mind and body, so we will try to utilize them.

[0008] Secondly, it is required that the vibrations include frequencies of 12Hz to 14Hz, preferably 12.25Hz to 13.75Hz, and most preferably 13Hz. The inventors, together with experts in geriatric medicine, attempted to conduct experimental studies on the effects of ultra-low frequency vibrations on elderly people with dementia. As a result, when several dementia patients and healthy individuals were exposed to ultra-low frequency vibrations containing a large amount of frequencies around 13 Hz, the dementia patients' working memory became more active. On the other hand, the healthy individuals became relaxed, and some even became sleepy. Incidentally, alpha waves, which are said to have a relaxing effect on humans, are in the 8-13Hz range, while beta waves, which are said to have an awakening effect on humans, are in the 13-30Hz range. Since 13Hz is on the boundary between alpha and beta waves, 13Hz can induce relaxation in some people and awakening in others. I believe that the hypothesis that vibrations around 13Hz activate the brains of dementia patients who are in an inactive state, while healthy individuals whose brains are awakened and secreting norepinephrine enter a relaxed meditative state, is not entirely off the mark. In other words, 13Hz, which lies at the boundary between alpha and beta waves, might induce the subject's current state in the opposite direction. As a side note, the standard note "A" is considered to be 440Hz. Dividing this by 2 to the power of 5 gives a lower harmonic of 13.75Hz (Mozart's standard note "A" is considered to be 422Hz, and dividing this by 2 to the power of 5 gives 13.1875Hz), which is an approximate value of 13Hz. Is this just a coincidence?

[0009] The aforementioned fused sound source data is based on superimposing inaudible ultra-low frequency data onto audible speech data, but sine waves, sawtooth waves, inverted sawtooth waves, or triangle waves may also be superimposed. The assumed frequency is 39 to 41 Hz, preferably 39.5 to 40.5 Hz, and most preferably 40 Hz. This allows users to not only enjoy music and other sounds, but also to be simultaneously exposed to low frequencies of approximately 40Hz and ultra-low frequencies of 20Hz or less. While it is believed that ultra-low frequency vibration data is sufficiently effective for dementia prevention, the reason for superimposing vibrations in the range centered around 40Hz is that there is a theory that 40Hz has the effect of reducing brain atrophy and preventing brain cell damage. While there are several commercially available and developing products that focus on the effects of 40Hz on the human brain, I have not heard of any examples that attempt to apply ultra-low frequency vibrations in conjunction with it.

[0010] The ultra-low frequency vibration preferably includes vibrations with frequencies of 10 Hz to 12 Hz, more preferably 10.5 Hz to 11.5 Hz, and most preferably 11 Hz, or vibrations with frequencies of 18 Hz to 20 Hz, more preferably 18.5 Hz to 19.5 Hz, and most preferably 19 Hz. As previously mentioned, 13 Hz may have beneficial effects on humans, but it seems that 11 Hz and 19 Hz also have effects. This is also a digression, but when the general frequency of Morse signals, 700 Hz, is divided by 2 to the power of 6, it becomes approximately 10.9 Hz. This is close to 11 Hz, but is it a coincidence?

Effects of the Invention

[0011] If the elderly who are at risk of dementia use the system of the present invention, they can easily receive ultra-low frequency vibrations.

Brief Description of the Drawings

[0012] [Figure 1] It is a diagram showing the system configuration according to an embodiment of the present invention. [Figure 2] It is a diagram showing the functional block configuration of a mobile terminal according to an embodiment of the present invention. [Figure 3] It is a processing flow diagram for explaining the operation of an application according to an embodiment of the present invention.

Modes for Carrying Out the Invention

[0013] The system of an embodiment of the present invention (hereinafter, "the present embodiment") will be described with reference to the drawings. In the following description, a mobile phone (smartphone) will be used as the information device.

[0014] FIG. 1 is a diagram for explaining the system configuration of the present embodiment. The mobile phone 1 can be connected to one or more arbitrary numbers of servers 2 via the communication network N. The server 2 has a function of transmitting ultra-low frequency vibration data and audio data (such as music and news) to the outside. In FIG. 1, there is only one server 2, but it may be composed of multiple servers. The user U who uses the mobile phone 1 can utilize various functions via a plurality of applications installed in the mobile phone 1. As one of such applications, there is a computer program (hereinafter, referred to as "Application A") that causes the mobile phone 1 to execute the generation and output of fused sound source data.

[0015] FIG. 2 is a diagram for explaining the configuration of the functional blocks of the mobile phone 1. The mobile phone 1 includes a fused sound source generation unit 3, an input unit 4, an audio reproduction unit 5, a screen output unit 6, a storage unit and a communication interface unit (not shown), etc. The input unit 4 is, for example, a touch panel. The audio reproduction unit 5 is, for example, a built-in or external speaker. The screen output unit 6 is, for example, a display screen.

[0016] The fused sound source generation unit 3 operates by starting Application A. The fused sound source generation unit 3 includes a sound source fusion control unit 3A, an ultra-low frequency vibration output unit 3B, an audio data reception unit 3C, a data fusion unit 3D, a fused sound source data output unit 3E, an ultra-low frequency vibration storage unit 3F, a user instruction setting unit 3G, and a vibration data display control unit 3H.

[0017] The sound source fusion control unit 3A controls the operation of the fused sound source generation unit 3. That is, it causes Application A to execute in response to instructions from the user U via the input unit 4, such as the start and end of the execution of Application A, the selection when there are multiple ultra-low frequency vibration data, and the setting change of various parameters of Application A. When Application A automatically starts when the power of the mobile phone 1 is turned on, the sound source fusion control unit 3A starts operating simultaneously.

[0018] The ultra-low frequency vibration output unit 3B automatically retrieves ultra-low frequency vibration data from the ultra-low frequency vibration storage unit 3F and outputs it from the audio playback unit 5 when the mobile phone 1 is powered on. The output is always active while the mobile phone 1 is powered on, but the user U may stop the output. For example, when there are people around the user U or when the battery level is low. Furthermore, the system may receive infrasound vibration data from server 2 at the user U's instruction. However, it is desirable that server 2 stores multiple infrasound vibration data sets collected from various power spots.

[0019] The audio data receiving unit 3C receives music, news, videos, etc. that user U wants to listen to from external sources such as server 2 and via a communication line.

[0020] When the audio data receiving unit 3C receives audio data, the data fusion unit 3D superimposes this audio data with ultra-low frequency vibration data to generate fused sound source data. Thus, the "fused sound source data" of this invention is basically data obtained by fusing audio data with ultra-low frequencies of 20 Hz or less. However, people who want to be exposed to ultra-low frequencies while working or reading may find audible music or television programs annoying. In such cases, it is sufficient to output only ultra-low frequencies that do not contain audible audio data, and in this specification, ultra-low frequencies output alone are also referred to as "fused sound source data." Furthermore, as will be described later, data generated by appropriately superimposing low frequencies of approximately 40 Hz is also referred to as "fused sound source data."

[0021] The fused sound source data output unit 3E outputs the data generated by the data fusion unit 3D to the audio playback unit 5. This allows user U to listen to music or watch dramas with superimposed ultra-low frequency signals.

[0022] The ultra-low frequency vibration memory unit 3F stores ultra-low frequency vibration data as data for application A. This data may be stored simultaneously with the installation of application A on the mobile phone 1, or it may be stored at any time if the ultra-low frequency vibration data received from server 2 is satisfactory.

[0023] The user instruction setting unit 3G starts and stops the execution of application A and changes various parameters based on instructions from user U via the input means 4. User U may use the default parameter values, or may change the parameter values ​​via the input unit 4. For example, if the amplitude of the audio data is large and unpleasant to the ear, the amplitude can be reduced, or the ratio of the amplitudes of the audio data and the infrasound data can be changed. In this way, the user can make various settings, enabling them to eliminate sound distortion and achieve a tone that is satisfactory to them.

[0024] The vibration data display control unit 3H displays the presence or absence of ultra-low frequency vibration data on the display screen 6, and performs various processes including control of starting, ending, and pausing the display, and changing the display color. However, the visualization function is optional. This is because ultra-low frequency vibrations are inaudible, and therefore this function is only necessary for users who want to confirm whether or not they are actually occurring. This concludes the explanation of the functional block configuration when application A is launched.

[0025] Next, referring to Figure 3, we will explain the operation when mobile phone 1 is powered on with application A already installed. User U turns on the power of mobile phone 1 (S201). If application A is already running (Yes in S202), it is determined whether infrasound vibration is being output (S203). Application A may start automatically when the power is turned on, or it may start upon explicit instruction from user U. Infrasound vibration is output to the audio playback unit 5 at the same time as application A starts. If app A is not yet running (No in S202), wait until user U instructs to start it (No in S204). If instructed (Yes in S204), proceed to S203.

[0026] The ultra-low frequency vibration data output in S203 may also be received from server 2, and the received data may be stored in the ultra-low frequency vibration memory unit 3F. If ultra-low frequency vibrations are not yet being output (No in S203), then output is started (S205).

[0027] If, while the output of ultra-low frequency vibration is occurring, i.e., while application A is running, user U issues a command to terminate application A via input unit 4 (Yes in S206), then the execution of application A will terminate (S210). If no termination instruction is given (No in S206), the system outputs ultra-low frequency vibrations while waiting for audio data to be transmitted (No in S207). When audio data is transmitted (Yes in S207), fused sound source data is generated by superimposing ultra-low frequencies (S208). The generated fused sound source data is output to the audio playback means (S209).

[0028] Even if ultra-low frequency vibration data is being output from the audio playback unit 5 or fused sound source data is being output, if user U issues a termination instruction for application A via the input unit 4 (Yes in S206), the execution of application A will terminate (S210). If there is no termination instruction (No in S206), the application will wait for audio data to be transmitted while outputting ultra-low frequency vibrations (S207). As described above, when audio data such as music is received, you hear audio data in a state where signals below 20Hz are fused together. When no audio data is received, only infrasound vibration data below 20Hz is transmitted. This vibration data is inaudible and cannot be heard, but you are exposed to infrasound vibrations that are expected to have an effect on dementia. In principle, the inaudible infrasound sound continues to play as long as the mobile phone 1 is powered on, so even when you are not listening to music or anything else, you can unknowingly obtain the preventive effect against dementia.

[0029] It should be noted that infrasound vibrations are inherently generated while application A is running. However, since these vibrations are inaudible, it is not clear to someone with normal hearing whether or not they are occurring. Therefore, for example, it would be beneficial to create a band-shaped area below the display image 6 of mobile phone 1 to visualize the frequency of the infrasound vibrations using color and brightness. The user should be able to toggle the display / hide of this area by tapping it or similar method.

[0030] Here, I would like to emphasize the extremely low-frequency vibrations used in this invention. In other words, not all vibration data below 20Hz is effective. Generally, frequencies in the 10-20Hz range, particularly around 11Hz, 13Hz, and 19Hz, seem to be appropriate. Furthermore, electronically generated vibration waves, such as those produced by specific algorithms, are less effective. For example, pure tones with only a single artificial frequency, like radio time signals, are typical examples. It appears that ultra-low frequency vibration data, extracted from audio data obtained from nature (for example, power spots) or recordings of musical instrument performances, containing only frequencies within a predetermined range, has an effect on the human mind and body. The inventor has experienced this firsthand in many cases, and will give one example below. An acquaintance of the inventor, who had suffered from insomnia and shallow sleep for a long time, played ultra-low frequency vibrations including 13Hz through a speaker. He fell asleep while sitting in a chair and slept soundly until the next morning. Incidentally, most musical instruments produce harmonics ranging from the 2nd to the 12th harmonic. For example, when you play the tonic C in C major, you also produce the 2nd harmonic (one octave higher), 4th harmonic (two octaves higher), and 8th harmonic (three octaves higher) C. The 3rd, 6th, and 12th harmonics produce the note G, while the 5th and 10th harmonics produce the note E. Thus, even if you intend to produce only the note C on an instrument, you are simultaneously producing the notes E and G. If you play multiple notes of different pitches at the same time, the variety of sounds produced simultaneously becomes richer. The exact reason why ultra-low frequency vibrations are effective is currently unclear. However, one possible factor is the progression, or harmony, of multiple sounds played simultaneously by multiple instruments (even chords played by a single piano). The aforementioned harmonics, as well as phenomena such as resonance and vibration that can occur between different instruments, may be intricately influencing each other, resulting in effects that would not occur with pure tones of the same frequency. This remains a challenge for the future.

[0031] On a different note, the aforementioned acquaintance who suffered from insomnia had placed a speaker in a position where the ultra-low frequency vibrations were directed at his abdomen. There is a theory that a lack of serotonin causes insomnia, and that 95% of this serotonin is produced in the gut. Therefore, it is possible that directing the ultra-low frequency vibrations to his abdomen was effective. It is fascinating to consider whether the same effect would have been obtained if the speaker had been placed on another part of the body, such as near the face, or whether ultra-low frequency vibrations may stimulate serotonin production. It would also be meaningful to consider the distribution of the vagus nerve and the aorta in the chest and abdomen, as well as to collect data from various types of subjects with different ages, genders, and personalities. Ultra-low frequency vibrations cannot be detected by human hearing. However, since vibrations are being generated, it is impossible that they have absolutely no effect on humans. Even if we cannot hear them, it is thought that our bodies are being exposed to them like sunlight. In the case of sunlight, exposure is not simply a matter of receiving it on the body's surface for a moment; various effects occur (for example, sunbathing is said to boost immunity and improve bone health). Similarly, isn't it possible that exposure to ultra-low frequency vibrations has some effect on, for example, the vagus nerve? At the very least, it's unreasonable to definitively say that there is absolutely no effect.

[0032] User U may use the default parameter values, but may also change the parameter values ​​via the input section 4. For example, if the amplitude of the audio data is large and the sound is distorted and unpleasant, it would be good to be able to reduce the amplitude, or change the ratio of the amplitude of the audio data to that of the infrasound. It would be beneficial to include a feature that allows users to preview the fused sound source data after changing parameter values. If repeated parameter changes and previews result in a more comfortable listening experience, users will likely listen to music on their mobile phones more often, naturally increasing their exposure to infrasound and contributing to dementia prevention. Furthermore, to facilitate user-friendliness, a simplified version of a maximizer screen would be helpful.

[0033] I would like to add a note here, specifically regarding sound pressure levels. For example, suppose a speaker can express a sound pressure range of -100 to +100. If the sound pressure range of the audible data is -80 to +80 and the sound pressure range of the inaudible data is -70 to +70, then the sum of the two at the same time will be a value in the range of -150 to +150. In this case, the speaker cannot express the sound, and the sound will be distorted. To avoid this, one possible method is to apply a limiter to either the audible or inaudible data to cut off sound pressure above (or below) a certain level, or to apply a compressor to the combined data of audible and inaudible data to compress the overall sound pressure. Of course, some users prefer distorted sounds, so limiter and compressor functions might be unnecessary for them. However, providing adjustable parameters allows you to cater to a variety of user types.

[0034] The above is an overview of the processing in this embodiment. The IT company or telecommunications company that provides application A can provide various information to user U who has installed application A via the communication network N. For example, this could include providing information such as the optimal frequency for ultra-low frequency vibrations determined from the latest research and survey results. It could also include distributing updated versions when application A is updated.

[0035] Since the scope of the present invention is determined based on the claims, the above is merely one example of an embodiment of the present invention. For example, it could be a mobile phone, or even a tablet device. However, for the elderly, who are the primary users of this invention, a small, lightweight, and portable mobile phone is more suitable.

[0036] In the above embodiment, when there is no audio data, basically only infrasound is played, but it is also acceptable to play a low frequency of approximately 40 Hz simultaneously. It would be good to allow the user to choose whether or not to play this low frequency. Furthermore, although it is said that around 40 Hz is effective in preventing dementia, it is also acceptable to change to a low frequency of other frequencies. What is important for this invention is to easily implement a type of music therapy using infrasound vibrations. Around 40 Hz is merely a parameter. Depending on the progress of research by future researchers, effective frequencies other than around 40 Hz may be discovered.

[0037] There are several possible methods for generating fused sound source data that includes a low frequency of approximately 40 Hz, but two examples are given below. Here, we will refer to the low frequency of approximately 40 Hz as the "basic carrier wave." The first method involves generating a basic carrier wave in real time when audio data is played from the mobile terminal 1, generating a composite carrier wave by superimposing an ultra-low frequency on this basic carrier wave, and generating fused sound source data by amplitude modulating the audio data with this composite carrier wave. The second method involves generating a basic carrier wave in real time when audio data is played from the mobile device 1, and then generating fused sound source data by superimposing ultra-low frequency data onto the modulated data obtained by amplitude modulating the audio data with this basic carrier wave.

[0038] In the above embodiment, the ultra-low frequency vibration data is received from an external server or stored as data within the app and then played back. However, a function to extract ultra-low frequency vibration data from the user's favorite music data may be added to app A. Furthermore, the combination of music data and ultra-low frequency vibration data is arbitrary. For example, even if the music data is intense music like hip-hop, it is acceptable to combine it with ultra-low frequency vibration data extracted from a relaxed ballad.

[0039] The effects of infrasound vibrations on humans, particularly whether there is an effective frequency, and whether 13Hz has opposite effects on dementia patients and healthy individuals, remain largely unknown. Nevertheless, it seems certain that it has a positive effect on dementia patients. Just because many things are not yet understood does not mean that we should not use systems that generate infrasound vibrations. In today's rapidly aging society, I believe that we should pursue both elucidation of the principles and practical application in parallel. [Industrial applicability]

[0040] This invention is expected to be in demand as a system or method that appears to be effective in slowing the progression of dementia or preventing it. At the very least, it could serve as a starting point for the development of devices and systems for dementia patients. [Explanation of Symbols]
