  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  1 and 2 are diagrams for explaining one embodiment of the present invention. The vibration generating apparatus 10 according to the present embodiment is devised to give the user a sense of security and to assist the user to fall asleep. Specifically, the vibration generator 10 generates vibrations based on heart motion sounds. Here, according to the knowledge obtained by the inventors of the present invention, the vibration based on the motion sound of the heart can give comfort to those who experience it, or can support the sleep of those who experience it. Furthermore, the vibration generator 10 of the present embodiment is also suitable for use in an environment where there is a roommate such as a hospital room. This is because the vibration generated by the vibration generator 10 is perceived only by the user who is in contact with the vibration generator 10 and not perceived by the surroundings.

  As shown in FIG. 1, the vibration generating device 10 includes a vibration generating unit 20 that generates vibration based on the motion sound of the heart, and a container 30 that stores the vibration generating unit 20. The container 30 has a cushioning property, and makes the vibration generator 10 feel comfortable. In particular, in the example shown in FIG. 1, the container 30 is a stuffed animal, and it is easy for an infant to hold the vibration generator 10. The container 30 has a cavity 31 in which the vibration generating means 20 is disposed, and the cavity 31 can be accessed by opening a lid 32 provided at the bottom of the container 30. ing. Therefore, by opening the lid 32, the vibration generating means 20 can be arranged in the cavity 31 or the vibration generating means 20 can be taken out from the cavity 31.

  FIG. 2 is a block diagram showing the overall configuration of the vibration generating means 20. As shown in FIG. 2, the vibration generating means 20 includes a vibrating vibrator 21, a data storage unit 22 that stores a plurality of vibration generation data 22 </ b> A, 22 </ b> B, and 22 </ b> C, and a vibration generation stored in the data storage unit 22. And a drive unit 23 that drives the vibrator 21 to vibrate based on the use data 22A, 22B, and 22C. In the example illustrated in FIG. 2, the data storage unit 22 is a detachable recording medium such as a memory card, but is not limited thereto. Further, the vibration generating means 20 has a changeover switch 24 for selecting one of a plurality of vibration generating data 22A, 22B, and 22C stored in the data storage unit 22. The vibration generating means 20 includes a power source 25 and a timer switch 26, and the power source 25 can supply power to the drive unit 23 via the timer switch 26.

  The vibration generation data 22A, 22B, and 22C are generated based on motion sounds of different human (human) hearts. The vibration generation data 22A, 22B, and 22C are generated by the following method, for example. That is, when a child uses the vibration generator 10, particularly, the operation of the heart of the person (human) via a stethoscope or a microphone applied to the chest of the child's guardian or the like. Sound is acquired over multiple cardiac cycles. Next, noise is removed from the acquired heart motion sound using a computer. Here, for example, when acquiring heart motion sound from a human (human), the noise is a stethoscope or microphone applied to the human (human) and clothes worn by the human (human), It is a sound generated by rubbing. Alternatively, noise is an irregular heart sound. Next, heart motion sounds for several heart cycles preferable for use as vibration generation data 22A, 22B, and 22C are collected from the heart motion sounds from which noise has been removed. The vibration generating data 22A, 22B, and 22C are generated by adjusting the strength of the heart operating sound in the first few seconds and the last several seconds of the collected heart operating sounds, and the vibration generating means 20 generates vibrations. Even if the data 22A, 22B, and 22C are repeatedly used continuously, the vibration of the vibrator 21 that is driven based on the vibration generation data 22A, 22B, and 22C starts from the end of the vibration generation data 22A, 22B, and 22C. Do not become unnatural when moving to the beginning. The data storage unit 22 may store only a single vibration generation data 22A. In this case, the vibration generating unit 20 may not have the changeover switch 24.

  The drive unit 23 drives the vibrator 21 to vibrate based on the vibration generation data selected by the changeover switch 24 among the vibration generation data 22A, 22B, and 22C generated as described above. In the example illustrated in FIG. 2, the drive unit 23 includes a voltage signal generation unit 231 and a vibration adjustment unit 232. The voltage signal generation unit 231 reproduces the vibration generation data selected by the changeover switch 24 among the plurality of vibration generation data 22A, 22B, and 22C generated as sound data, and uses the obtained sound pressure as the voltage signal. Convert to The vibration adjusting unit 232 adjusts the magnitude of vibration of the vibrator 21 that is driven based on the vibration generation data. Specifically, the vibration adjusting unit 232 is a variable resistor, and adjusts the magnitude of the voltage signal generated by the voltage signal generating unit 231 and transmits the adjusted voltage signal to the vibrator 21. In the example illustrated in FIG. 2, the vibrator 21 is a voltage element that vibrates based on an electric signal provided by the drive unit 23.

  The drive unit 23 is stopped when a predetermined time elapses after a timer 27 described later is started. Specifically, when the time measured by the timer 27 reaches a preset time, the drive unit 23 is electrically disconnected from the power supply 25. The drive unit 23 drives the vibrator 21 to vibrate when an impact is applied to the vibration generating means 20. Specifically, when an impact detection sensor 27a described later detects that an impact is applied to the vibration generating means 20, the drive unit 23 is electrically connected to the power source 25.

  The timer switch 26 includes a switch 26a that electrically connects or disconnects the power supply 25 and the drive unit 23, a timer 27, and an impact detection sensor 27a. When the impact detection sensor 27a detects that an impact has been applied to the vibration generator 10, the timer 27 is activated and starts measuring time. In addition, the timer 27 ends timing when the measured time of the timer 27 reaches a preset time. The switch 26 a is switched when the timer 27 starts measuring time, and electrically connects the power supply 25 and the drive unit 23. Further, the switch 26a is switched when the timer 27 finishes timing, and electrically disconnects the power supply 25 and the drive unit 23. By configuring the timer switch 26 in this way, the drive unit 23 drives the vibrator 21 to vibrate when the impact detection sensor 27a detects that the vibration generating means 20 has been impacted. Therefore, even when the vibration generating means 20 is housed in the container 30, if the vibration generating apparatus 10 is hit or shaken to give an impact to the vibration generating means 20, the vibration generating means 20 generates vibration. be able to. For this reason, it is possible to cause the vibration generating means 20 to generate vibration without removing the vibration generating means 20 from the container 30.

  Next, the operation of the present embodiment configured as described above will be described.

  First, a plurality of vibration generation data 22A, 22B, and 22C generated by the above-described method are recorded on a recording medium such as a memory card. Next, the recording medium is installed in the vibration generating means 20 as the data storage unit 22. Then, the time measured by the timer 27 is set. In addition, the selector switch 24 selects one of the plurality of vibration generation data 22A, 22B, and 22C stored in the data storage unit 22. Then, the lid 32 of the housing 30 is opened, and the vibration generating means 20 is housed in the cavity 31 of the housing 30.

  In this state, when an impact is applied to the vibration generator 10 by hitting or shaking, the impact is detected by the impact sensor 27a of the timer switch 26, and the timer 27 is activated to start timing. At this time, the switch 26a is switched, and the power source 25 and the drive unit 23 are electrically connected. When the drive unit 23 and the power source 25 are electrically connected, the voltage signal generation unit 231 of the drive unit 23 reproduces the vibration generation data selected by the changeover switch 24, and the obtained sound pressure is converted into the voltage signal. Is converted to In the vibration adjusting means 232 of the driving unit 23, the magnitude of the voltage signal is adjusted. A voltage signal whose voltage magnitude is adjusted is transmitted to the vibrator 21, and the vibrator 21 vibrates. The vibration of the vibrator 21 is transmitted to the user via the container 30.

  When the time measured by the timer 27 reaches a preset time, the timer 27 ends the time measurement. At this time, the switch 26a is switched, and the power source 25 and the drive unit 23 are electrically disconnected. Thereby, the supply of the voltage signal from the drive unit 23 to the vibrator 21 is stopped, and the vibrator 21 stops vibrating.

  When the vibration is applied to the vibration generator 10 again in a state where the vibrator 21 has stopped vibrating, the impact is detected by the impact sensor 27a, and the timer 27 starts measuring time. At this time, the switch 26a is switched, and the power source 25 and the drive unit 23 are electrically connected again. As a result, the drive unit 23 resumes the supply of the voltage signal to the vibrator 21, and the vibrator 21 vibrates again.

  In the above description, the vibration generating means 20 generates vibration based on the motion sound of the heart, but is not limited thereto. For example, the vibration generating means 20 may be generated based on blood flow. Here, the blood flow is a pulse acquired by, for example, a pulse oximeter attached to a human fingertip or the like. In this case, the vibration generation data 22A, 22B, and 22C are generated by the following method, for example. That is, a pulse is acquired over a plurality of cardiac cycles via a pulse oximeter or the like attached to a human fingertip or the like. Next, using a computer, noise is removed from the acquired pulse. Here, the noise is, for example, an irregularly generated pulse. Thereafter, from the pulse from which the noise has been removed, a pulse for several heart cycles preferable for use as the vibration generation data 22A, 22B, and 22C is collected. The vibration generation data 22A, 22B, and 22C are generated by adjusting the strength of the pulse for the first few seconds and the last few seconds of the collected pulses, and the vibration generation means 20 generates the vibration generation data 22A, 22B, and 22C. Is continuously used repeatedly, when the vibration of the vibrator 21 driven based on the vibration generation data 22A, 22B, and 22C shifts from the end to the start of the vibration generation data 22A, 22B, and 22C. Try not to be unnatural. In addition, when the vibration generation means 20 is generated based on blood flow, the voltage signal generation means 231 of the drive unit 23 is based on vibration generation data indicating, for example, a change in strength of a pulse as a change in pressure. A voltage signal for driving the vibrator 21 is generated. In this case, the vibrator 21 is a voltage element that vibrates based on an electric signal given by the drive unit 23.

  Alternatively, the vibration generating means 20 may generate vibration based on electrocardiogram data. That is, the vibration generation data 22A, 22B, and 22C may be generated based on electrocardiogram data. In this case, the vibration generation data 22A, 22B, and 22C are generated by the following method, for example. That is, an electrode is attached to a human body, and electrocardiogram data is acquired over a plurality of cardiac cycles. Next, noise is removed from the acquired electrocardiogram data using a computer. Here, noise is, for example, electrical activity of the heart that occurs irregularly. Thereafter, electrocardiogram data for several cardiac cycles preferable for use as the vibration generation data 22A, 22B, and 22C is collected from the electrocardiogram data from which noise has been removed. The vibration generation data 20A, 22B, and 22C are generated by adjusting the strength of the electrical signals for the first few seconds and the last few seconds of the collected electrocardiogram data. Even if the data 22A, 22B, and 22C are repeatedly used continuously, the vibration of the vibrator 21 that is driven based on the vibration generation data 22A, 22B, and 22C starts from the end of the vibration generation data 22A, 22B, and 22C. Do not become unnatural when moving to the beginning. Note that when the vibration generating means 20 generates vibration based on the electrocardiogram data, the voltage signal generating means 231 of the drive unit 23 is, for example, vibration generating data 22A, 22B generated as electric signal data. , 22C, a voltage signal for driving the vibrator 21 is generated. In this case, the vibrator 21 is a voltage element that vibrates based on an electric signal given by the drive unit 23.

  Further, the vibration adjusting means 232 may adjust the vibration speed of the vibrator 21 driven based on the vibration generation data 22A, 22B, and 22C. In this case, for example, the vibration adjusting unit 232 adjusts the reproduction speed of the vibration generation data 22A, 22B, and 22C in the voltage signal generation unit 231.

  The vibration generator 10 can also be applied to childcare items other than stuffed animals, such as baby strollers, baby beds, swing chairs (so-called baby racks), child seats, and the like. In this case, the container 30 may be a seat body, a seat used for a stroller, a crib, a swing chair, a mattress, or a child seat. The vibration generator 10 can also be applied to children and adult bedding including infants. In this case, the container 30 may be a mattress, a pillow, a body pillow, or the like.
