Detailed Description
[ embodiment 1 ]
Hereinafter, an embodiment of the present disclosure will be described in detail. Unless otherwise specified in the present specification, "X to Y" representing a numerical range means "X or more and Y or less".
(outline of electronic System 1000)
The electronic system 1000 according to one embodiment of the present disclosure is a system for detecting vibration of an object and generating sound corresponding to the detected vibration. That is, the electronic system 1000 detects the vibration of the object and generates a sound corresponding to the frequency band of the component included in the detected vibration. Here, the vibration of the object may be solid, liquid, or gas vibration. The frequency band of the component included in the vibration may be, for example, a frequency band corresponding to an audible sound or a frequency band corresponding to an ultrasonic wave. The electronic system 1000 according to the present disclosure is applicable to, for example, stethoscopes, nondestructive inspection, and confirmation of internal operations of precision machines. Hereinafter, the "vibration of the object" is also expressed as "vibration from the object".
In this embodiment, a case where the electronic system 1000 is applied to a stethoscope will be described as an example. The electronic system 1000 detects vibrations from, for example, respiration of a subject (e.g., a patient), pulsation of the heart, blood flow in a blood vessel, movement of a digestive tract (e.g., peristaltic movement), and the like, and generates sounds corresponding to frequency bands of components included in the detected vibrations.
(Structure of electronic System 1000)
First, an outline of an electronic system 1000 according to one embodiment of the present disclosure will be described with reference to fig. 1. Fig. 1 is a schematic diagram of an electronic system 1000 according to an embodiment of the present disclosure.
The electronic system 1000 includes the electronic device 100 and the sound generation apparatus 2.
< Structure of electronic device 100 >
As shown in fig. 1, an electronic device 100 includes a gyroscopic vibrator 1 and a sound output unit 3. Fig. 1 shows a configuration in which the electronic device 100 includes one gyro-type vibrating meter 1 and one sound output unit 3, but is not limited thereto. For example, the electronic device 100 may have a configuration including a plurality of sound output units 3 for one gyro-type vibrating meter 1. This allows a plurality of users (for example, medical-related personnel) to simultaneously hear the sound corresponding to the vibration detected by the gyro-type vibrating meter 1.
The gyro-type vibrating meter 1 and the sound output unit 3 may be connected by wireless. In the case of wireless connection, connection may be performed by using Bluetooth (registered trademark), wifi (registered trademark), or the like, for example. Thus, even at a position where the gyro-type vibrator 1 is separated from the sound output unit 3, a sound corresponding to the detection signal can be output.
In fig. 1, the gyro-type vibration meter 1 and the sound output unit 3 are connected by wireless, but the present invention is not limited thereto. The gyro-type vibrating meter 1 and the sound output unit 3 may be connected by a wire.
In fig. 1, the electronic apparatus 100 is shown as not including the sound generation device 2, but the electronic apparatus 100 may include the sound generation device 2. In the case where the electronic device 100 includes the sound generation device 2, this function may be mounted on a control board 40, which will be described later, for example.
Structure of gyroscopic vibrating meter 1
The gyro-type vibration meter 1 is a vibration meter capable of detecting vibration of an object by contact with the object. When the object is the body of the patient, the gyro-type vibration meter 1 may be brought into contact with the chest, back, wrist, neck, abdomen, or the like of the patient. The gyro-type vibration meter 1 may be configured to receive vibrations of an object through a membrane 20 described later, and to detect vibrations generated in the membrane 20. The gyro-type vibrator 1 transmits a detection signal corresponding to the detected vibration.
The electronic device 100 shown in fig. 1 includes one gyro-type vibrating meter 1, but is not limited thereto. For example, the electronic device 100 may be provided with a plurality of gyro-type vibrators 1. As an example, the electronic device 100 may include a plurality of gyro-type vibrators 1 capable of detecting different frequencies, or may include a plurality of gyro-type vibrators 1 capable of detecting the same frequency. In addition, in the case where the electronic apparatus 100 includes a plurality of gyro-type vibrators 1, they may be disposed at positions point-symmetrical to each other.
The structure of the gyro-type vibrating meter 1 according to one embodiment of the present disclosure will be described with reference to fig. 2. Fig. 2 is a sectional view at line I-I of the gyro-type vibrating meter 1 shown in fig. 1. As shown in fig. 2, the gyro-type vibrating meter 1 according to one embodiment of the present disclosure includes a film 20, a support 30, a gyro sensor 12, a control board 40, a cover 25, and a battery 15.
According to the above configuration, the vibration of the object can be detected. Specifically, for example, the gyro-type vibrator 1 can detect vibrations of 20Hz to 20000 Hz.
[ Membrane 20]
The membrane 20 receives vibrations from the object. The membrane 20 deforms according to the received vibration. The film 20 is disposed on the support 30 so that a part thereof is positioned on the opening 11.
(1) Physical properties of film
The gyro-type vibrating meter 1 detects vibration by deformation of the membrane 20. Therefore, physical properties such as film thickness, young's modulus, density, acceptable sound velocity, and the like of the film 20, that is, the material used for the film 20 and the shape of the film affect the sensitivity of vibration detection of the gyro-type vibration meter 1, which are performed on the deformation of the film 20.
The thickness of the film 20 may be 10 to 5000. Mu.m. From the viewpoint of good sensitivity to vibrations, the vibration may be 20 to 2000. Mu.m, or 50 to 1000. Mu.m. The film thickness of the film 20 may be uniform throughout the film, or may be different depending on the portion of the film 20.
The Young's modulus of the film 20 may be 0.1MPa to 1000GPa. From the viewpoint of good sensitivity to vibrations, the vibration may be 0.5 to 500GPa or 1MPa to 400GPa. The method for measuring the young's modulus of the film 20 is not particularly limited, and is, for example, a method using a 3-point bending test.
The density of the film 20 may be 100 to 5000kg/m 3 . From the viewpoint of good sensitivity to vibration, the vibration can be 500 to 4000kg/m 3 May be 800-2000 kg/m 3
Further, the vibration receiving sensitivity of the film 20 can be evaluated by the sound velocity (m/s) of the acceptable vibration. It can be said that the higher the sound velocity of the vibration that the membrane 20 can accept, the higher the vibration acceptance sensitivity of the membrane 20. Since the sound velocity is obtained by dividing the value of young's modulus by the value of density, it can be said that the higher the young's modulus of the film 20 is, the lower the density is, the higher the sound velocity of acceptable vibration is, that is, the higher the sensitivity is. The sound velocity that can receive the vibration of the membrane 20 may be 10 to 20000m/s. From the viewpoint of good sensitivity to vibrations, the vibration may be 100 to 15000m/s or 1000 to 15000m/s.
The material of the film 20 is not particularly limited as long as it is a material in the above-described ranges of film thickness, young's modulus, density, and sound velocity, and examples thereof include silicone, glass epoxy resin, ABS (acrylonitrile butadiene styrene), CFRP (carbon fiber reinforced plastic), urethane, epoxy, and the like. From the viewpoint of receiving vibration with good sensitivity, silicone, glass epoxy, and CFRP may be used, or CFRP may be used.
The film 20 having different physical properties may be selected according to the frequency of vibration of the detection object. For example, in the case of detecting high-frequency vibration, a relatively hard material, that is, a material having a high young's modulus may be selected as the film 20. In addition, the film thickness of the film 20 may be increased. In the case of detecting vibration at a low frequency, a soft material, that is, a material having a low young's modulus may be selected as the film 20. In addition, the film thickness of the film 20 can also be reduced. In the case where the electronic device 100 includes a plurality of gyro-type vibrators 1, for example, the film 20 having different physical properties for each gyro-type vibrator 1 may be provided.
(2) Shape of the film
The membrane 20 is disposed on the support 30. The film 20 may be disposed so as to cover the entire opening 11. Since the membrane 20 covers the entire opening 11, the area of the membrane 20 for receiving vibration from the object is large, and vibration can be received with good sensitivity.
Here, an embodiment of the gyro-type vibrating meter in which the membrane 20 covers the entire opening 11 will be described. Fig. 3 is a plan view of the gyro-type vibration meter 1j in a case where the entire opening 11 is covered with the film 20j as viewed from the control substrate side. In fig. 3, the film 20j has a central region 21j covering the center of the opening 11 and a peripheral region 22j extending from the central region 21j toward the support 30. In fig. 3, the portion constituted by the edge of the support 30 is shown as a circular shape, but the shape of the portion constituted by the edge of the support 30 may be an ellipse, a polygon, or the like.
In the case where the film 20j covers the entire opening 11, the film 20j may be a single film made of one material, and the central region 21j and the peripheral region 22j may be made of different materials. In the case where the central region 21j and the peripheral region 22j are made of different materials, the central region 21j may be harder than the peripheral region 22j. For example, the central region 21j and the peripheral region 22j may be made of materials having different young's moduli. The young's modulus of the central region 21j may be higher than that of the peripheral region 22. This allows the vibration to be received with good sensitivity.
Examples of the material of the central region 21j include silicone, glass epoxy, ABS (acrylonitrile butadiene styrene), CFRP (carbon fiber reinforced plastic), polyurethane, epoxy, aluminum, copper, iron, chromium, gold, silver, titanium, aluminum oxide, zirconium oxide, aluminum nitride, and glass. Examples of the material of the peripheral region 22j include silicone, glass epoxy, ABS (acrylonitrile butadiene styrene), CFRP (carbon fiber reinforced plastic), polyurethane, and epoxy.
On the other hand, the central region 21j may be softer than the peripheral region 22 j. In this case, for example, when the film 20j receives vibration from the object, the film 20j can be easily brought into contact with the object.
The thicknesses of the central region 21j and the peripheral region 22j may be different from each other. In this case, for example, correction/adjustment of the variation in resonance characteristics due to manufacturing can be easily performed.
Further, the film 20 may be disposed so as to cover a part of the opening 11. In the case where the film 20 is disposed so as to cover a part of the opening 11, the area, the weight, and the like of the film 20 can be adjusted.
The shape of the film 20 in the case of covering a part of the opening 11 will be described with reference to fig. 4 to 11. Fig. 4 to 11 are plan views of the gyro-type vibrators 1a to 1h when viewed from the control substrate side. In fig. 4 to 11, the portions other than the films surrounded by the support members 30, 30e correspond to the openings 11. In fig. 4 to 11, all of the gyro-type vibrators 1a to 1h are provided with one gyro sensor 12 at a position close to the support body 30 on the film 20. The details of the configuration of the gyro sensor 12 will be described later. Fig. 4, 6, 8 and 10 show examples in which the portion constituted by the edge of the support 30 is circular, and fig. 5, 7, 9 and 11 show examples in which the portion constituted by the edge of the support 30 is quadrangular. However, the shape of the portion constituted by the edge of the support 30 is not limited to this, and may be an ellipse, a polygon, or the like.
The gyro-type vibration meter 1 may have a peripheral region 22 extending in a band shape from the central region 21 to the support 30. In fig. 4, a membrane 20a of the gyro-type vibrator 1a includes a central region 21 covering the center of the opening 11, and a plurality of peripheral regions 22 extending from the central region 21 to the support 30. This allows the vibration to be received and detected with good sensitivity. In one example, the central region 21 may be circular, or may be disposed in a region including the center of a circle formed by the edges of the support 30. The outer peripheral portion of the central region 21 may be any one of the outer peripheral portions, and the distance from the point to the edge (the portion shown by the broken line in fig. 4) of the nearest support 30 may be equal. The shape of the central region 21 is not limited to this, and may be an ellipse, a polygon, or the like.
In the gyro-type vibration meter 1a, the number of peripheral regions 22 is 4, and the respective peripheral regions 22 may have the same length. Alternatively, the opposing peripheral regions 22 may be the same length as each other, and the lengths of adjacent peripheral regions 22 may be different from each other.
The central region 21 and the peripheral region 22 may be made of the same material or may be made of different materials. In the case of being composed of different materials, the central region 21 may be harder than the peripheral region 22. This allows the vibration to be received with good sensitivity. Examples of the material of the central region 21 include silicone, glass epoxy, ABS (acrylonitrile butadiene styrene), CFRP (carbon fiber reinforced plastic), polyurethane, epoxy, aluminum, copper, iron, chromium, gold, silver, titanium, aluminum oxide, zirconium oxide, aluminum nitride, glass, and the like. Examples of the material of the peripheral region 22 include silicone, glass epoxy, ABS (acrylonitrile butadiene styrene), CFRP (carbon fiber reinforced plastic), polyurethane, and epoxy.
On the other hand, the central region 21 may be softer than the peripheral region 22. In this case, for example, when the film 20a receives vibration from the object, the film 20a can be easily brought into contact with the object.
The central region 21 and the peripheral region 22 may have different thicknesses. In this case, for example, correction and/or adjustment of the deviation of the resonance characteristics caused by the manufacturing can be easily performed.
In fig. 4, the gyro-type vibrator 1a has one gyro sensor 12 on the peripheral region 22. The arrangement of the gyro sensor 12 will be described in detail later, but the gyro sensor 12 may be arranged not in the central area 21 but in the peripheral area 22. The number of gyro sensors 12 is not limited to one, and a plurality of gyro sensors may be provided in the film 20.
The central region 21 may have a predetermined area or more for receiving vibrations from the object, but if the area is excessively large, the peripheral region 22 for disposing the gyro sensor 12 becomes short. Therefore, the area of the central region 21 may be 10% to 80% of the area of the circle formed by the edges of the support 30.
In fig. 5, a membrane 20g of the gyro-type vibrator 1g includes a central region 21g and a peripheral region 22g extending from the central region 21g to the support 30e in a portion including the center of a quadrangle formed by the edges of the support 30 e. The central region 21g corresponds to a reduced quadrilateral shape formed by the edges of the support 30 e. In other words, the diagonal line of the quadrangle constituted by the edges of the support body 30e and the diagonal line of the central area 21g may also be arranged to overlap. The peripheral region 22g may be arranged to include lines connecting the centers of the sides of the quadrangle formed by the edges of the support 30e and the centers of the sides of the central region 21 g.
In fig. 6, a membrane 20d of the gyro-type vibrator 1d includes a central region 21d and a peripheral region 22d. The gyro-type vibrator 1d can also be said to be a system in which two peripheral regions 22 having a longitudinal direction in the Y-axis direction are removed from the gyro-type vibrator 1a shown in fig. 4. The area of the membrane 20d is smaller than the membrane 20a of the gyro-type vibrator 1a shown in fig. 4, and the weight of the whole membrane 20d is reduced, so that the membrane 20d is easily deformed by vibration.
In fig. 7, a membrane 20h of the gyro-type vibrator 1h includes a central region 21h and a peripheral region 22h. The gyro-type vibrator 1h can also be said to be a system in which two peripheral regions 22g having a longitudinal direction in the Y-axis direction are removed from the gyro-type vibrator 1g shown in fig. 5. The area of the membrane 20h is smaller than the membrane 20g of the gyro-type vibrator 1g shown in fig. 5, and the weight of the whole membrane 20h is reduced, so that the membrane 20h is easily deformed by vibration.
In fig. 8, the membrane 20b of the gyro-type vibrator 1b has a + (plus) shape. The center region 21b of the +type film 20b is arranged to include the center of a circle constituted by the edges of the support 30. In fig. 8, the film 20b is shown as an example of a shape in which the film is formed of a peripheral region 22b having a longitudinal direction in the X-axis and a peripheral region 22b having a longitudinal direction in the Y-axis, and these cross at right angles, but the present invention is not limited thereto. For example, the intersection of the +type films 20b may be an angle other than a right angle. The film 20b may be a film obtained by cutting 1 film into a +type film or may be a film obtained by intersecting 2 elongated films. In the case where the film 20b is formed by intersecting 2 long films, the 2 films may be made of different materials or the same material.
The membrane 20b of fig. 8 can also be said to be a system in which the circular central region 21 is removed from the membrane 20a of fig. 4. The area of the film 20b in fig. 8 for receiving vibration from an object is smaller than that of the film 20a in fig. 4, but the weight of the entire film is reduced, so that the film 20b is easily deformed with vibration.
In fig. 9, a support 30e of the gyro-type vibrator 1e has a quadrangular shape. The film 20e has a positive type shape as in the film 20b of fig. 8. The ends of the film 20e are fixed to the centers of the sides of the quadrangular support 30 e. The film 20e of fig. 9 can also be said to be a film in which the center region 21g of the quadrangular shape is removed from the film 20g of fig. 5. The membrane 20e of fig. 9 has a smaller area for receiving vibrations from an object than the membrane 20g of fig. 5, but the weight of the whole membrane is reduced, so that the membrane 20e is easily deformed by the vibrations.
In fig. 10, the membrane 20c of the gyro-type vibrator 1c has a thin, short strip shape and is disposed at a position corresponding to the diameter of a circle formed by the edge of the support 30. The film 20c is fixed at both ends at positions symmetrical with respect to the center of a circle formed by the edges of the support 30. The film 20c of fig. 10 can also be said to be a system in which the peripheral region 22b having a longitudinal direction in the Y-axis direction is removed from the film 20b of fig. 8. The area of the film 20c in fig. 10 for receiving vibration from the object is smaller than that of the film 20b in fig. 8, but the weight of the entire film is reduced, so that the film 20c is easily deformed by vibration.
In fig. 11, the membrane 20f of the gyro-type vibrator 1f has a short strip shape, similar to the membrane 20c of fig. 10. Both end portions of the film 20f are fixed at positions including the centers of the sides of the support 30 e. The film 20f of fig. 11 can also be said to be a system in which the peripheral region 22e having a longitudinal direction in the Y-axis direction is removed from the film 20e of fig. 9. The membrane 20f of fig. 11 has a smaller area for receiving vibrations from an object than the membrane 20e of fig. 9, but the weight of the whole membrane is reduced, so that the membrane 20f is easily deformed by the vibrations.
In fig. 5, 7, 9 and 11, the support 30e is shown as a square, but the square may be a square, a rectangle, or a parallelogram. In fig. 9 and 11, the central regions 21g and 21h may have a square shape, a rectangular shape, or a parallelogram shape. The diagonal of the quadrangle formed by the edges of the support body and the diagonal of the central area do not have to overlap.
In fig. 5, 7, 9 and 11, the end portions of the films 20e, 20f, 20g and 20h are fixed at the positions including the center portion of one side of the quadrangle formed by the edges of the support body, but the fixed positions are not limited thereto. For example, the film may be disposed on a diagonal line of a quadrangle formed by the edges of the support, and the end of the film may be fixed to a corner of the quadrangle formed by the edges of the support.
Although not shown, 2 or more films may be arranged in parallel in a short stripe shape without intersecting each other.
In fig. 3 to 11, the shape of the films 20a to 20h and 20j when the films are viewed from the control board 40 side is described, but returning to fig. 2, the shape of the films when viewed from the cross section of the gyro-type vibration meter 1 may be, for example, a disk shape. The disk shape means a convex shape with respect to the object to be detected for vibration, in other words, a concave shape with respect to the bottom surface of the support 30. The support 30 according to the present embodiment has the concave portion 13 as described below, but the support 30 may not necessarily have the concave portion 13 as long as the membrane 20 has a disk shape and a space in which the membrane 20 can vibrate can be ensured. In addition, the membrane 20 may be flat. That is, the film 20 may have a planar shape along the opening.
[ support 30]
The support 30 supports the membrane 20. As shown in fig. 2, the support 30 has a recess 13 having an opening 11. The recess 13 may have a bottom. By having the bottom portion, the film 20 is less susceptible to deformation by pressure from the side opposite to the opening portion 11 side. The depth of the concave portion 13 is not particularly limited, and may be a depth at which the membrane 20 does not contact the inner surface of the concave portion 13 when the membrane 20 vibrates. Thus, the membrane 20 does not contact the inner surface of the recess 13, and vibration of the membrane 20 is not hindered by the inner surface.
The support 30 holds the film 20 in a state where a given tension is applied to the film 20. Thus, the film 20 does not flex, and the gyro sensor 12 fixed to the film 20 can detect vibration of the film with good sensitivity.
The film 20 and the support 30 may be fixed by the adhesive portion 16. The adhesive portion 16 may be a portion using a known adhesive, or may be a portion in which an end portion of the film 20 is fitted into the support 30. Examples of the adhesive include a resin material such as epoxy resin and a metal material such as solder. When a metal material is selected as the adhesive, the absorption of vibration by the adhesive can be reduced, and the vibration characteristics of the film 20 can be improved. In addition, when the resin material is selected as the adhesive, transmission of vibration from the support 30 to the film 20 can be reduced, and noise can be reduced.
The film 20 may be fixed to the upper surface of the support 30. The film 20 may be disposed on the inner side surface of the concave portion 13 of the support 30, or may be fixed to the bottom surface of the concave portion 13 when the depth of the concave portion 13 is shallow.
The material of the support 30 is not particularly limited, but the support 30 may be made of a harder material than the film 20 so that the film 20 vibrates only with respect to the vibration of the object. Examples of the material of the support 30 include resin, metal, and ceramic.
In order to prevent the support 30 from vibrating, the support 30 may be covered with a soft material. Examples of the soft material include silicone rubber and urethane rubber. The material for covering the support 30 may be different from the covering portion 25 described later, and may cover only the support 30.
Cover 25
The gyro-type vibration meter 1 may further include a cover portion 25 disposed between the membrane 20 and the object. According to the above configuration, the film 20 on which the gyro sensor 12 is disposed does not directly contact the object. In order for the cover 25 to transmit vibration to the membrane 20, the cover 25 may be in contact with the membrane 20.
The cover 25 may be made of the same material as the film 20 or a different material. The cover 25 may be made of, for example, a waterproof material. This allows the gyro-type vibrator 1 to be cleaned, and allows the gyro-type vibrator 1 to be held in a sanitary manner. The cover 25 may be made of an antibacterial material, for example. This enables the gyrometer 1 to be held hygienically. The cover 25 may be made of an adhesive material. This can improve the adhesion between the gyro vibration meter 1 and an object (for example, a patient's body), and can detect vibrations with high sensitivity.
[ other films ]
The gyro-type vibration meter 1 may have a multilayer structure including a film in addition to the cover portion 25 and the film 20. In the case where the gyro-type vibration meter 1 has a multilayer structure, only any one of the plurality of films may be fixed to the support 30. In the case where a plurality of films are present, the plurality of films may be bonded to each other or may be positioned close to each other in order to avoid loss of vibration of the object. In the case where the gyro-type vibration meter 1 has a multilayer structure, the material, young's modulus, size, and the like of each film may be different.
Gyro sensor 12
The gyro sensor 12 is a sensor for detecting vibration emitted from an object as an angular velocity. As shown in fig. 2, the gyro sensor 12 is disposed on a surface of the film 20 on the side covering the opening 11. Thereby, the gyro sensor 12 detects the vibration of the diaphragm 20 accompanying the vibration of the object.
The gyro sensor 12 may be any known gyro sensor as long as it can detect vibration as an angular velocity. For example, a single axis gyroscopic sensor.
The gyro sensor 12 may include a driving arm that excites bending vibration, a detection arm that detects bending vibration, an electrode that excites the driving arm, and an electrode that converts vibration of the detection arm into an electrical signal. An example of the structure of the gyro sensor 12 will be described later. The gyro sensor may be a crystal oscillator using a crystal as a raw material.
The gyro sensor 12 and the film 20 may be fixed by an adhesive, a resin coating, or an electrical connection material such as solder or silver paste.
The structure in which the gyro sensor 12 detects vibration of the film 20 will be described. Fig. 12 shows an example of the gyro sensor 12. Fig. 12 is an enlarged view of a region 50 of the film 20a of fig. 4. The gyro sensor 12 includes driving arms 1201, 1202, a detection arm 1203, and a fixing portion 1204. Although not shown, the gyro sensor 12 may include electrodes to which driving signals for exciting the driving arms 1201 and 1202 are input and electrodes for converting vibrations of the detection arm 1203 into electrical signals. The driving arms 1201 and 1202 and the detection arm 1203 are fixed to a fixing portion 1204 having a longitudinal direction in the Y-axis direction and a longitudinal direction in the X-axis direction. The driving arms 1201, 1202 excite bending vibration in the X-axis direction. When angular velocity around the Z axis is applied in a state where bending vibration of the driving arms 1201, 1202 is excited, the angular velocity around the Z axis is detected by detecting the bending vibration by the detecting arm 1203. Thereby, the gyro sensor 12 can detect the vibration of the film 20 as the angular velocity.
From the viewpoint of detecting vibrations with good sensitivity, the gyro sensor 12 has the driving arms 1201 and 1202 and the detection arm 1203 of the gyro sensor 12 arranged perpendicular to the longitudinal direction of the film 20a having the longitudinal direction in the X-axis direction. Further, for example, in the case where the gyro sensor 12 is provided in the peripheral region 22 having the longitudinal direction in the Y-axis direction in the film 20a of fig. 4, the gyro sensor 12 may be arranged such that the driving arms 1201, 1202 and the detection arm 1203 of the gyro sensor 12 are perpendicular to the longitudinal direction of the film 20 a.
In addition, when the membrane 20 is deformed by receiving vibration of the object, the gyro sensor 12 may be disposed at a position where a change in slope per unit time in the membrane is maximum. The slope of the film refers to the angle of the film relative to the initial state of no amplitude. When the membrane 20 is deformed by receiving vibration of the object, an "abdomen" having a maximum amplitude and the most wobbling of the displacement occurs in the membrane, but the slope is zero, and a "node" having a maximum slope and the amplitude is zero. The position where the change in the slope of the film is greatest is referred to as the position of the "knuckle". In addition, the "abdomen" and the "node" appear at different positions due to the frequency of vibration.
The position on the film 20 where the gyro sensor 12 is disposed will be described. Fig. 13 is a graph showing a change in the slope of the film per unit time according to vibration at a predetermined frequency, and is a graph in which the maximum value of the change in the slope is normalized to 1. The vertical axis represents the value of the change in the slope of the film per unit time, and the horizontal axis represents the relative position of the film 20 where the position corresponding to the "abdomen" is set to 0. The "abdomen" corresponds to the center of the membrane 20. As an example, the dotted line indicates 670Hz, the broken line 170Hz, and the solid line indicates a change in the slope of the film according to vibration at 970 Hz. In the graph shown by the dotted line, the position a where the change in slope is greatest is located farthest from the center of the film 20. In the graph shown by the broken line, the position b at which the change in the slope is greatest is located closer to the center of the film 20 than the position a, and in the graph shown by the solid line, the position c at which the change in the slope is greatest is located closest to the center of the film 20. In this way, the position of the film where the change in the slope of the film becomes maximum is different depending on the value of the frequency of vibration. Therefore, the gyro sensor 12 is disposed at a position where the change in the slope per unit time is maximum, and thus the frequency of vibration to be detected can be detected with good sensitivity.
The gyro-type vibrator 1 may have a plurality of gyro sensors 12 arranged on the film 20 and capable of detecting vibrations in different frequency bands. When the membrane 20 is deformed by receiving vibration in a frequency band to be detected, the gyro-type vibration meter 1 may have a plurality of gyro sensors 12 at respective positions in the membrane 20 where a change in slope per unit time is largest. This allows vibration in a wide frequency band to be detected with good sensitivity.
The gyro-type vibration meter 1 includes a plurality of gyro sensors 12 arranged on the film 20, and the plurality of gyro sensors 12 may be arranged on at least one radial line from the center of the opening 11. Thereby, vibrations in different frequency bands can be detected.
The gyro-type vibration meter 1 may have a plurality of gyro sensors 12 arranged on the membrane 20, and the plurality of gyro sensors 12 may be arranged in a propagation direction of vibration of the membrane 20 when displacement of the center of the membrane 20 is maximum. Thereby, vibrations in different frequency bands can be detected.
Fig. 14 shows a gyro-type vibrating meter 1i, which is a diagram for explaining the position where the gyro sensor 12 is disposed. The gyro-type vibrator 1i includes gyro sensors 12a, 12b, and 12c at different positions in the peripheral region 22 in the X-axis direction. The gyro sensors 12a, 12b and 12c are arranged on at least one radial line from the center of the opening 11, that is, the center of the central region 21. The gyro sensors 12a, 12b, and 12c can receive vibrations from the object and be aligned along the propagation direction of the vibrations of the film 20 when the displacement of the center of the film 20 is maximum. For example, the gyro sensors 12a, 12b, and 12c may be arranged at positions corresponding to the positions a, b, and c shown in fig. 13, respectively. For example, when the film 20 is deformed by receiving vibration at a frequency of 670Hz, the gyro sensor 12a may be disposed at a position in the film 20 where the change in slope per unit time is maximum. When the gyro sensor 12b receives vibration at 170Hz and the gyro sensor 12c receives vibration at 970Hz and the film 20 is deformed, the gyro sensor 12b may be disposed at a position in the film 20 where the change in slope per unit time is greatest. By providing the plurality of gyro sensors 12 capable of detecting vibrations in different frequency bands in this way, vibrations in a wide frequency band can be detected with good sensitivity.
The gyro-type vibration meter 1 may further include the gyro sensor 12 at a position of the membrane 20 that corresponds to the point symmetry with respect to the center of the membrane 20. The gyro-type vibration meter 1i of fig. 14 includes gyro sensors 12a ', 12b ' and 12c ' at corresponding positions point-symmetrical with respect to the gyro sensors 12a, 12b and 12c, respectively, with respect to the center of the film 20. The gyro sensors 12a ', 12b ', and 12c ' detect vibrations of the same frequency as the gyro sensors 12a, 12b, and 12c, respectively, with the same sensitivity. In this way, the gyro-type vibrating meter 1 can detect vibration more accurately by disposing the gyro sensor 12 at a corresponding position point-symmetrical with respect to the center of the membrane 20.
The gyro sensor 12 may have a minimum temperature dependence of sensitivity for detecting vibration at-40 to 85 ℃. In addition, the gyro sensor 12 may have a minimum temperature dependence at 10 to 85 ℃ and a minimum temperature dependence at 34 to 43 ℃. According to the above configuration, since the temperature dependence of the gyro sensor 12 is reduced at a temperature close to the body temperature of the human, the vibration from the human body can be detected with good sensitivity.
[ control Board 40]
Returning to fig. 2, the gyro-type vibration meter 1 includes a control board 40 for controlling the gyro sensor 12 connected to the gyro sensor 12 via the wiring 14. The control board 40 is disposed in the recess 13. The control board 40 is a board for converting the angular velocity of the vibration input from the gyro sensor 12 into an electrical signal. According to the above configuration, the gyro-type vibrator 1 can convert the angular velocity of vibration input from the gyro sensor 12 into an electric signal.
The wiring 14 connecting the gyro sensor 12 and the control board 40 has flexibility. Since the wiring 14 has flexibility, the wiring 14 does not hinder the vibration of the film 20. Specific examples of the material of the wiring 14 include rubber, CFRP, GFRP (glass fiber reinforced plastic), and the like. Particularly, by using GFRP having high flexibility, the wiring 14 can detect vibration with good sensitivity without blocking vibration of the film 20.
The form of the wiring 14 is not limited to this, and the wiring 14 may be printed on the surface of the cover film 20 on the opening 11 side or on the inner wall of the support 30. Thus, the wiring 14 does not hinder vibration of the film 20.
The control board 40 may also include a communication unit 41 that transmits the detection signal of the gyro sensor 12 to an external device. Thereby, the detection signal of the gyro sensor 12 can be transmitted to an external device. The mode of transmitting the detection signal of the gyro sensor 12 to the external device will be described in detail in embodiment 2.
[ accumulator 15]
The gyro-type vibration meter 1 may be provided with a battery 15 for supplying electric power to the control board 40. The battery 15 and the control board 40 can be connected via the wiring 17. The gyro-type vibrator 1 is provided with the battery 15, so that the gyro-type vibrator 1 can be easily transported, and there is an advantage that the place where the gyro-type vibrator 1 is used is not limited. The gyro-type vibrating meter 1 may be provided with a battery instead of the battery 15, or may be connected to an external power source.
Sound output unit 3-
Returning to fig. 1, the sound output unit 3 outputs sound data generated based on the detection signal of the gyro sensor 12. The audio data outputted from the audio output unit 3 may be audio data generated by the audio generating apparatus 2 described later based on the detection signal of the gyro sensor 12, for example. In fig. 1, the sound output unit 3 is an earphone, but is not limited thereto, and may be a speaker, for example. The sound generation device 2 and the sound output unit 3 may be connected by a wire or by a wireless. From the viewpoint of portability of the sound output unit 3, the sound generation device 2 and the sound output unit 3 can be connected by wireless, and the wireless system includes the use of Bluetooth (registered trademark), wiFi (registered trademark), and the like. The audio output unit 3 may further include a display device. The display device may display a waveform of vibration corresponding to the sound, a spectrum chart showing vibration, a time waveform of vibration, a value of frequency of vibration, or the like. Examples of the display device include a display.
< Sound Generation device 2>
The sound generation device 2 generates a sound corresponding to the received detection signal. In other words, the sound generation device 2 converts the electric signal as the detection signal into sound data. The sound generation device 2 is, for example, a computer. The sound generation device 2 transmits the generated sound data. When the gyro-type vibrator 1 detects vibrations of a plurality of different frequencies, the sound generation device 2 may combine the detected vibrations of different frequencies to generate sound when generating sound data.
The gyro-type vibrating meter 1 and the sound generation device 2 may be connected by a wire or by a wireless connection. From the viewpoint that the sound corresponding to the detection signal can be generated even at a position where the gyro-type vibrator 1 is separated from the sound generating apparatus 2, wireless connection is possible. In the case where the gyro-type vibration meter 1 and the sound generation device 2 are connected by wireless, for example, use of Bluetooth (registered trademark), wiFi (registered trademark), or the like is given.
[ embodiment 2 ]
In this embodiment, a description will be given of a mode of the gyro-type vibrating meter 1 that removes vibration that becomes noise. The gyro-type vibrating meter 1 can receive vibrations from an object and vibrations from other objects. Therefore, the detection signal overlaps with the detection signal corresponding to the vibration from the object and the detection signal corresponding to the vibration from the object. The vibration from the other objects may be, for example, vibration from the operation of the support. The operation of the support may be, for example, hand shake of a user holding the gyro-type vibration meter 1. When vibrations from objects other than the object are detected in an overlapping manner, it is difficult for the gyro-type vibrating meter 1 to accurately detect vibrations from the object. According to the gyro-type vibrator 1 of the present embodiment, the detection signal corresponding to the vibration from the other objects can be removed from the detection signal.
The gyro-type vibration meter 1 of the present embodiment may include a first gyro sensor disposed on the film and a second gyro sensor disposed on the film or the support. The sound generation device 2 may generate sound data based on the first detection signal of the first gyro sensor and the second detection signal of the second gyro sensor. In this case, the sound data based on the first detection signal and the second detection signal is output to the sound output section 3. The sound generation device 2 may perform arithmetic processing such as addition or subtraction of the first detection signal and the second detection signal to generate sound data.
Fig. 15 is a plan view of the gyro-type vibration meter 1k according to one embodiment of the present disclosure, as viewed from the control board 40 side, and shows an example in which two gyro sensors are provided on a film, the two gyro sensors facing the same gyro-type vibration meter. Here, as shown in fig. 12, the gyro sensor includes driving arms 1201 and 1202 and a detection arm 1203. The driving arms 1201, 1202 and the detecting arm 1203 extend in opposite directions along the longitudinal direction in the Y-axis direction, respectively. The direction of the gyro sensor means the direction shown by the driving arms 1201, 1202 and the detecting arm 1203. In order to indicate the direction of the gyro sensor, a black circle in fig. 15 is attached to the direction in which the driving arms 1201, 1202 extend, as an example. The gyro-type vibrator 1k includes gyro sensors 12d and 12e in a peripheral region 22 of the film 20 a. The gyro sensors 12d and 12e are arranged in the same direction as each other. The gyro sensors 12d and 12e are disposed at axisymmetric positions with respect to a line (Y-axis in fig. 15) passing through the center of the film 20 a. Since the two gyro sensors are arranged at axisymmetric positions, the two gyro sensors can detect vibrations of the same frequency band.
In the gyro-type vibrator 1k, since the directions of the two gyro sensors are arranged to be identical along the Y-axis direction, noise can be removed by subtracting detection signals corresponding to vibrations detected by the respective gyro sensors. For example, when the support 30, that is, the gyro-type vibrator 1k vibrates as a whole, the gyro sensors 12d and 12e detect vibrations in the same frequency band as each other. Therefore, by subtracting the common detection signal from the two gyro sensors and removing the same, only the detection signal of the film 20a can be obtained.
Such as shown in fig. 16. Fig. 16 is a diagram showing detection signals corresponding to vibrations detected by the two gyro sensors 12d and 12e, and as an example, the signal Sd is the detection signal of the gyro sensor 12d and the signal Se is the detection signal of the gyro sensor 12 e. The signal indicated by the dotted line in the signal Sd and the signal Se is mainly a detection signal corresponding to the vibration of the support 30, and is a detection signal common to the signal Sd and the signal Se. The signal shown by the solid line is mainly a detection signal corresponding to the vibration of the film 20 a. When the film 20a vibrates, the gyro sensor 12d and the gyro sensor 12e tilt in mutually opposite directions according to the slope of the film, and thus detection signals obtained from the respective gyro sensors indicate mutually opposite phases. When the signals Sd and Se are subtracted (Sd to Se), the detection signal corresponding to the vibration of the support 30, which is common to the signals Sd and Se, is removed, and the detection signal corresponding to the vibration of the film 20a is obtained. Further, a detection signal corresponding to the vibration of the film 20a is amplified. This can remove the detection signal corresponding to the vibration of the support 30, amplify the detection signal corresponding to the vibration of the film 20a, and acquire the detection signal corresponding to the vibration from the object.
In fig. 15 and 16, a method of removing noise by subtracting detection signals corresponding to vibrations detected by two gyro sensors is described. In the case where the orientations of the two gyro sensors are arranged in the Y-axis direction in opposition, noise can be removed even if the detection signals of the two gyro sensors are added.
Fig. 17 is a plan view of the gyro-type vibration meter 1p according to one embodiment of the present disclosure, as viewed from the control board 40 side, and shows an example of a gyro-type vibration meter in which two gyro sensors 12f and 12g are provided on a film, and the directions of the two gyro sensors are opposite along the Y-axis direction. The direction of the gyro sensor is opposite to that of the center of a circle formed by the edges of the support body 30, and the center is located at a point-symmetrical position. The gyro-type vibrator 1p includes gyro sensors 12f and 12g in a peripheral region 22 of the film 20 a. The directions of the sensors of the gyro sensor 12f and the gyro sensor 12g are opposite to each other along the Y-axis direction, but the positions to be arranged are axisymmetric positions with respect to a line (Y-axis in fig. 17) passing through the center of the film 20 a.
Since the directions of the two gyro sensors 12f and 12g are opposite to each other along the Y axis direction, the gyro-type vibrating meter 1p can remove noise by adding detection signals corresponding to vibrations detected by the respective gyro sensors. For example, when the support 30, that is, the gyro-type vibrator 1p vibrates as a whole, the gyro sensors 12f and 12g detect vibrations of the same frequency as each other in opposite phases. Therefore, by adding and removing the detection signals shared by the two gyro sensors, only the detection signal of the film 20a can be obtained.
Specifically, fig. 18, for example. Fig. 18 is a diagram showing detection signals corresponding to vibrations detected by the two gyro sensors 12f and 12g, and as an example, the signal Sf is the detection signal of the gyro sensor 12f and the signal Sg is the detection signal of the gyro sensor 12 g. The signals shown by the solid and dotted lines are the same as in fig. 16. Since the directions of the vibrating gyro sensors 12f and 12g of the support body 30 are opposite, the signals indicated by the solid lines indicate phases opposite to each other. In contrast, when the film 20a vibrates, the gyro sensor 12f and the gyro sensor 12g tilt in opposite directions according to the slope of the film, but since the directions of the gyro sensors are opposite, the detection signals obtained from the respective gyro sensors indicate the same phase as each other. When the signal Sf and the signal Sg are added (sf+sg), only the detection signal corresponding to the vibration of the support 30 common to the signal Sf and the signal Sg is removed, and only the detection signal corresponding to the vibration of the film 20a is obtained. Further, a detection signal corresponding to the vibration of the film 20a is amplified. This can remove noise, which is a detection signal corresponding to the vibration of the support 30, amplify the detection signal corresponding to the vibration of the film 20a, and obtain a detection signal corresponding to the vibration from the object.
In fig. 15 to 18, the two gyro sensors, that is, the first gyro sensor and the second gyro sensor, are disposed axisymmetrically with respect to a line (Y axis) passing through the center of the film 20a, but the two gyro sensors may be disposed at positions other than the axisymmetric positions of the film. By disposing the two gyro sensors at positions other than axisymmetric positions, vibrations in different frequency bands of the respective gyro sensors can be detected.
Fig. 19 is a plan view of the gyro-type vibrating meter 1m according to one embodiment of the present disclosure, as viewed from the control board 40 side. The gyro-type vibrator 1m is an example of a gyro-type vibrator having two gyro sensors 12h and 12i provided in the film 20a, the positions of the two gyro sensors being located at positions other than axisymmetric with respect to a line passing through the center of the film. The gyro-type vibrator 1m includes the gyro sensor 12i in the film 20a in the peripheral region 22, and includes the gyro sensor 12h in the peripheral region 22. The direction of each gyro sensor is the same along the Y-axis direction. Since the gyro sensors 12h and 12i detect vibrations in different frequency bands, detection signals in a wider frequency band can be obtained by subtracting detection signals corresponding to these vibrations.
Specifically, fig. 20, for example. Fig. 20 is a diagram showing detection signals corresponding to vibrations detected by the two gyro sensors 12h and 12i, where the signal Sh is the detection signal of the gyro sensor 12h and the signal Si is the detection signal of the gyro sensor 12 i. The signals shown by the solid and dotted lines are the same as in fig. 16. As with the gyro-type vibrator 1k described above, the gyro sensor 12h and the gyro sensor 12i tilt in mutually opposite directions according to the slope of the film when the film 20a vibrates, and thus the detection signals obtained from the respective gyro sensors indicate mutually opposite phases. Further, vibrations in different frequency bands are detected from the gyro sensors 12h and 12i, and when the signal Sh and the signal Si are subtracted (Sh to Si), only the detection signal corresponding to the vibrations of the support body 30, which is common to the signal Sh and the signal Si, is removed. Thereby, the detection signal corresponding to the vibration of the film 20a includes two frequency bands. As a result, a detection signal corresponding to the vibration of the support 30, that is, noise, can be obtained, and a detection signal corresponding to the vibration of the film 20a, that is, a detection signal corresponding to the vibration from the object in a wide frequency band can be obtained.
In fig. 15 to 20, the description has been made of a case where two gyro sensors, that is, the first gyro sensor and the second gyro sensor are arranged on the film, but one of the two gyro sensors may be arranged on the support.
Fig. 21 is a plan view of the gyro-type vibration meter 1n according to one embodiment of the present disclosure, as viewed from the control board 40 side, and shows an example of a gyro-type vibration meter in which one gyro sensor is disposed on each of the film and the support. The gyro-type vibrator 1n includes a gyro sensor 12j in the peripheral region 22 of the film 20a, and a gyro sensor 12k in the side wall of the support 30.
Since the gyro-type vibrator 1n includes the gyro sensor in the film 20a and the support 30, the detection signal corresponding to the vibration of the support 30 is subtracted from the detection signal corresponding to the vibration of the film 20a, and the detection signal corresponding to the vibration of the film 20a alone can be obtained.
Specifically, fig. 22, for example. Fig. 22 is a diagram showing detection signals corresponding to vibrations detected by the two gyro sensors 12j and 12k, where the signal Sj is the detection signal of the gyro sensor 12j and the signal Sk is the detection signal of the gyro sensor 12k. The signals shown by the solid and dotted lines are the same as in fig. 16. Since the signal Sk is mainly a detection signal corresponding to the vibration of the support 30, if the signal Sj and the signal Sk are subtracted (Sj to Sk), the detection signal corresponding to the vibration of the support 30, which is common to the signal Sj and the signal Sk, is removed, and a detection signal corresponding to the vibration of the film 20a is obtained. This removes the detection signal corresponding to the vibration of the support 30, and obtains the detection signal corresponding to the vibration of the film 20a, that is, the vibration from the object.
In the above embodiment, the gyro-type vibrating meter including two gyro sensors has been described, but the number of gyro sensors is not limited to this. For example, four gyro sensors may be provided in total in each of the four peripheral regions 22 of the film 20a, and detection signals of the two gyro sensors located at positions symmetrical to the X-axis and the Y-axis may be added or subtracted. For example, the peripheral region 22 shown in fig. 14 may be provided with a plurality of gyro sensors, and detection signals of adjacent gyro sensors 12a and 12b may be added or subtracted.
According to the embodiment described in this embodiment, a gyro-type vibrating meter having excellent detection sensitivity with noise removed can be realized. If the detection sensitivity of the gyro-type vibrator is improved in this way, for example, the detection signal can be imaged, and breathing sounds such as 200Hz components which are not recognized audibly can be detected. The detection signal of the first gyro sensor and the detection signal of the second gyro sensor may be output by the electronic system 1000 or 1000a described later, instead of being calculated by the control board 40 of the gyro-type vibration meter 1, and may be added or subtracted by the sound generator 2.

The management server 4 may be capable of distributing at least one of the stored detection signal and sound data to the external device 6.
According to the above configuration, the electronic system 1000a can distribute a detection signal or sound data to an external device.
