[First Embodiment]
(Vibration generation module)
First, a vibration generating element serving as a vibration generating module mounted on the electronic device according to the first embodiment will be described.

  As shown in FIGS. 1 and 2, the vibration generating element 100 according to the present embodiment includes a housing body 10, a lid 20, a vibrating body 30, an elastic support member 40, permanent magnets 51 and 52, a yoke 61, 62 etc. The casing of the vibration generating element in the present embodiment is formed by the casing main body 10 and the lid 20.

  The housing main body 10 is formed by processing a metal plate, has a substantially rectangular parallelepiped box shape, is formed by a bottom surface and four side surfaces around the bottom surface, and is opened. A member for forming the vibration generating element is inserted from the portion where the vibration is generated. The housing body 10 is formed in a substantially rectangular shape in which the Y1-Y2 direction is the longitudinal direction and X1-X2 is the short direction, and the four side surfaces are the longitudinal direction of the bottom surface, that is, the Y1-Y2 direction. Are formed by two opposing side surfaces in the longitudinal direction and two lateral sides in the short direction, that is, in the X1-X2 direction.

  The lid portion 20 is a substantially rectangular plate-like member formed by processing a metal plate, and is formed so that the open portion of the housing body portion 10 can be covered by the lid portion 20. ing.

  As shown in FIG. 3, the vibrating body 30 is an electromagnet, and includes a magnetic core 31, a coil 32 formed by winding an electric wire around the magnetic core 31, flanges 33 and 34, and the like. The magnetic core 31 is made of a ferromagnetic material such as iron and has a prismatic shape. The coil 32 is formed by winding an electric wire substantially perpendicular to the longitudinal direction of the magnetic core 31, that is, the Y1-Y2 direction. The flanges 33 and 34 are attached in the vicinity of both ends of the magnetic core 31 in the longitudinal direction. Three protrusions 33a, 33b, and 33c are provided on the upper surface side of the flange 33, that is, the side in the Z1 direction. Of these, the protrusion 33a and the protrusion 33c are used as terminals. Although not shown in the drawings, both ends of the electric wire forming the coil 32 are entangled.

  Thus, although not shown in figure, the electrode terminal of the one side of FPC70 is connected to the projection parts 33a and 33c with which the electric wire was wound. Further, an external circuit (not shown) is connected to the other side of the FPC 70, and current is supplied to the coil 32 from the external circuit (not shown) via the FPC 70.

  As shown in FIGS. 4 and 5, the elastic support member 40 is formed by processing a metal plate having a spring property into a predetermined shape. It is formed by spring portions 42 provided on both sides of the portion 41. 4 is a perspective view of the elastic support member 40, and FIG. 5 is a front view thereof.

  The spring portion 42 is a leaf spring, and is formed by bending a metal plate that is long in the X1-X2 direction along the Y1-Y2 direction. Of the two spring portions 42, one spring portion 42 is formed on the X1 direction side from the holding portion 41, and the other spring portion 42 is formed on the X2 direction side from the holding portion 41. Yes.

  Specifically, as shown in FIG. 5, the spring portion 42 has three bent portions 43 a, 43 b, 43 c, two flat portions 44 a, 44 b, and a connection portion 45. Each of the bent portions 43a, 43b, and 43c is a portion that is bent along the Y1-Y2 direction. The flat portion 44a is formed between the bent portion 43a and the bent portion 43b, and the flat portion 44b is , Formed between the bent portion 43b and the bent portion 43c. The flat portions 44a and 44b are formed so that the shape viewed from the X1 direction side or the X2 direction side is substantially rectangular.

  A leaf spring having a folding structure such as the elastic support member 40 shown in FIGS. 4 and 5 is easily deformed in the direction perpendicular to the fold, that is, in the X1-X2 direction and the Z1-Z2 direction, but along the fold. In other words, the Y1-Y2 direction is not easily deformed. Therefore, the elastic support member 40 is elastically deformed in the X1-X2 direction by expansion and contraction and elastically deformed in the Z1-Z2 direction by bending, but the deformation in the Y1-Y2 direction is suppressed.

  Further, in a leaf spring having a bent structure such as the elastic support member 40, in general, the ease of elastic deformation differs between the Z1-Z2 direction due to bending and the X1-X2 direction due to expansion and contraction. Therefore, when the elastic coefficient in the X1-X2 direction of the elastic support member 40 is the first elastic coefficient and the elastic coefficient in the Z1-Z2 direction of the elastic support member 40 is the second elastic coefficient, the first elastic coefficient is It becomes a value different from the second elastic modulus.

  In addition, a connecting portion 45 is formed at the end of the one spring portion 42 in the X1 direction of the elastic support member 40, and a connecting portion 45 is formed at the end of the other spring portion 42 in the X2 direction. Is formed. Accordingly, the bent portion 43 c is between the flat portion 44 b and the connecting portion 45. At both ends in the longitudinal direction of the connecting portion 45 of the elastic support member 40, that is, at the end in the Y1 direction and at the end in the Y2 direction, connecting claw portions 45a are provided, respectively. The elastic support member 40 can be attached to the inside of the housing body 10 by connecting to the inside of the side surface in the short direction. Therefore, the elastic support member 40 is connected to the housing main body 10 in a state in which it can be elastically deformed in the X1-X2 direction and the Z1-Z2 direction with respect to the housing main body 10.

  As shown in FIGS. 6 and 7, the vibrating body 30 is put in and held in a holding portion 41 in the elastic support member 40. In this way, the vibrator 30 placed in the holding portion 41 of the elastic support member 40 vibrates in the X1-X2 direction by the first natural frequency determined by the first elastic coefficient and the mass of the vibrator 30; It vibrates in the Z1-Z2 direction by the second natural frequency determined by the second elastic coefficient and the mass of the vibrating body 30. Since the first elastic coefficient and the second elastic coefficient are different values, the first natural frequency and the second natural frequency are also different values.

  The vibrating body 30 formed of an electromagnet generates a magnetic field by passing a current through the coil 32 and generates a magnetic flux along the Y1-Y2 direction. Is done. That is, the magnetized polarities of the magnetic core 31 in the Y1 direction and the Y2 direction are different. For this reason, when an alternating current is passed through the coil 32, the generated magnetic field becomes an alternating magnetic field in which the direction of the magnetic field changes in accordance with the change in the direction of the current. Therefore, the state where the Y1 direction side of the magnetic core 31 is the S pole and the Y2 direction is the N pole and the state where the Y1 direction side of the magnetic core 31 is the N pole and the Y2 direction is the S pole are alternately repeated. The timing for generating the alternating magnetic field in the vibrating body 30 and the frequency of the alternating magnetic field are controlled by an external circuit (not shown) connected to the coil 32.

  The permanent magnets 51 and 52 are formed in a substantially square plate shape. As shown in FIG. 8, the permanent magnets 51 and 52 are installed in the longitudinal direction of the vibrating body 30, that is, on an extension line in the Y1-Y2 direction, respectively, in the housing body 10. Specifically, in the housing body 10, the magnetic cores 31 of the vibrating body 30 are respectively installed on the extension lines in the Y1-Y2 direction, and the permanent magnet 51 is on the extension line of the magnetic core 31 of the vibrating body 30 in the Y1 direction. Is installed, and the permanent magnet 52 is installed on an extension line in the Y2 direction. In the permanent magnets 51 and 52, the widest substantially square surface is a magnetized surface, and the magnetized surface of the permanent magnet 51 and the end surface in the Y1 direction of the magnetic core 31 of the vibrating body 30 are opposed to each other. The magnetization surface and the end surface in the Y2 direction of the magnetic core 31 of the vibrating body 30 are opposed to each other. FIG. 8 is a perspective view of the vibration generating element according to the present embodiment in a state where the lid 20 and the FPC 70 are removed, and shows the inside of the vibration generating element.

  In the housing body 10, the Y1 direction side outside the permanent magnet 51 is made of a ferromagnetic material such as iron in order to direct the magnetic flux generated from the permanent magnet 51 toward the vibrating body 30. The yoke 61 is provided and is formed of a ferromagnetic material such as iron on the Y2 direction side outside the permanent magnet 52 in order to direct the magnetic flux generated from the permanent magnet 52 toward the vibrating body 30 side. A yoke 62 is provided.

  As shown in FIG. 9, the permanent magnets 51 and 52 are divided into two regions by a diagonal line indicated by a broken line from the upper left corner to the lower right corner so that the regions have different polarities. Magnetized. In FIG. 9, the permanent magnet 51 is shown for convenience.

  In the present application, the lower left region of the permanent magnet 51, that is, the region on the X1 direction and the Z2 direction side is defined as the first magnetization region 51a, and the upper right region of the permanent magnet 51, that is, the X2 direction and the Z1 direction side. The region is described as the second magnetization region 51b. The permanent magnet 51 is magnetized so that the first magnetization region 51a is an S pole and the second magnetization region 51b is an N pole. The same applies to the permanent magnet 52, but the polarities are different. That is, although not shown, the permanent magnet 52 is provided with a first magnetization region and a second magnetization region so that the first magnetization region is an N pole and the second magnetization region is an S pole. Is magnetized.

  Next, the operation of the vibration generating element according to the present embodiment will be described with reference to FIGS. In the vibration generating element in the present embodiment, an alternating magnetic field is generated by flowing an alternating current through the coil 32 of the vibrating body 30 formed by an electromagnet, and the longitudinal direction of the magnetic core 31, that is, both ends in the Y1-Y2 direction are Magnetize to have different polarities. The permanent magnet 51 and the permanent magnet 52 are disposed so as to face each other with the vibrating body 30 interposed therebetween. The first magnetization region 51a of the permanent magnet 51 and the first magnetization region of the permanent magnet 52 are opposed to each other. The second magnetization region 51b of the magnet 51 and the second magnetization region of the permanent magnet 52 are opposed to each other. Accordingly, the first magnetization region 51 a of the permanent magnet 51 facing the first magnetization region of the permanent magnet 52 is magnetized to have a different polarity, and the second magnetization region of the facing permanent magnet 51 is 51b and the 2nd magnetization area | region of the permanent magnet 52 are magnetized by the different polarity.

  In the present embodiment, as shown in FIG. 10A, when the end of the magnetic core 31 of the vibrating body 30 is magnetized to the N pole, the end of the magnetic core 31 on the Y1 direction side is An attractive force attracted to the first magnetization region 51a of the permanent magnet 51 and a repulsive force repelling the second magnetization region 51b are generated. At this time, although not shown, since the end of the magnetic core 31 of the vibrating body 30 on the Y2 direction side is magnetized to the S pole, the end of the magnetic core 31 on the Y2 direction side is attracted to the first magnetization region of the permanent magnet 52. The repulsive force that repels the attractive force and the second magnetization region is generated. As a result, the vibrating body 30 moves toward the X1 direction or the Z2 direction as indicated by the broken-line arrows.

  10B, when the end of the magnetic core 31 of the vibrating body 30 on the Y1 direction side is magnetized to the south pole, the end of the magnetic core 31 on the Y1 direction side of the permanent magnet 51 A repulsive force repelling the first magnetization region 51a and an attractive force attracted to the second magnetization region 51b are generated. At this time, although not shown, since the end of the magnetic core 31 of the vibrating body 30 on the Y2 direction side is magnetized to the N pole, the end of the magnetic core 31 on the Y2 direction side repels the first magnetized region of the permanent magnet 51. A repulsive force and an attractive force attracted to the second magnetization region are generated. As a result, the vibrating body 30 moves toward the X2 direction or the Z1 direction as indicated by the dashed arrow.

  Therefore, in the vibration generating element in the present embodiment, an alternating magnetic field is generated by passing an alternating current through the coil 32 of the vibrating body 30 formed of an electromagnet, and accordingly, an attractive force and a permanent magnet are generated. Repulsive force is generated, and the vibration body 30 repeats the movement toward the X1 direction or the Z2 direction and the movement toward the X2 direction or the Z1 direction, thereby generating vibration.

  By the way, the vibrating body 30 is supported by the elastic support member 40 as described above, and is along the X1-X2 direction by the first natural frequency determined corresponding to the first elastic coefficient and the mass of the vibrating body 30. And vibrates along the Z1-Z2 direction with a second natural frequency determined corresponding to the second elastic coefficient and the mass of the vibrating body 30.

  When an alternating magnetic field having the same frequency as the first natural frequency is generated in the vibrating body 30 formed of an electromagnet, the vibrating body 30 vibrates in the X1-X2 direction as shown in FIG. It becomes easy to do. Therefore, the vibrating body 30 vibrates along the X1-X2 direction. Further, when an alternating magnetic field having the same frequency as the second natural frequency is generated in the vibrating body 30 formed of an electromagnet, the vibrating body 30 is in the Z1-Z2 direction as shown in FIG. It becomes easy to vibrate. Therefore, the vibrating body 30 vibrates along the Z1-Z2 direction. In addition to being able to vibrate with a particularly large amplitude at the same frequency as the first natural frequency and the second natural frequency, it is also possible to vibrate at frequencies close to the first natural frequency and the second natural frequency. Therefore, it is possible to generate vibrations at a wide frequency compared to a structure having only one natural frequency.

  Thus, the vibration generating element in the present embodiment changes the vibration in the X1-X2 direction and the vibration in the Z1-Z2 direction and the direction of vibration by changing the frequency of the alternating current flowing in the coil 32 of the vibrating body 30. be able to. The current flowing through the coil 32 may be a pulse wave having a predetermined frequency instead of the alternating current. Even in this case, an attractive force and a repulsive force are generated in either direction when energized, and when the current is not energized, the recovery by the elastic force of the elastic support member 40 is repeated at a predetermined frequency. And vibration in the Z1-Z2 direction can be generated.

  That is, the vibration generating element 100 can generate vibration in the Z1-Z2 direction and vibration in the X1-X2 direction. In this way, the vibration plate 130 to which the vibration generating element 100 is attached vibrates due to the vibration generated in the vibration generating element 100, and the vibration in the vibration plate 130 vibrates through the vibration transmitting member 140. Thereby, the tactile sensation due to the vibration can be transmitted to the finger of the hand touching the surface side of the surface plate 110.

  In the present embodiment, the vibration generating element 100 can generate vibration in the Z1-Z2 direction and vibration in the X1-X2 direction. When vibration in the Z1-Z2 direction is generated by the vibration generating element 100, the vibration plate 130 also vibrates in the Z1-Z2 direction due to the vibration in the Z1-Z2 direction of the vibration generating element 100. The vibration transmission member 140 bonded to the vibration plate 130 is in a state where the head 141 of the vibration transmission member 140 is supported by the step portion 123 c of the through hole 123 in the through hole 123 of the housing unit 120. The vibration transmitting member 140 is movable in the Z1-Z2 direction, can vibrate the surface plate 110 in the Z1-Z2 direction, and can transmit the vibration in the Z1-Z2 direction to a finger or the like of a human hand. In the present embodiment, the number of vibration transmitting members 140 is larger than the number of vibration generating elements 100.

  When vibration in the X1-X2 direction is generated by the vibration generating element 100, the vibration plate 130 also vibrates in the X1-X2 direction due to the vibration in the X1-X2 direction of the vibration generating element 100. Since the vibration transmitting member 140 bonded to the diaphragm 130 has a gap formed between the through hole 123 of the housing unit 120 and the through hole 123, the vibration transmitting member 140 is movable in the X1-X2 direction. The surface plate 110 can be vibrated in the X1-X2 direction, and the vibration in the X1-X2 direction can be transmitted to a finger or the like of a human hand as a tactile sensation.

  Therefore, in the electronic device according to the present embodiment, two types of vibrations having different vibration directions can be transmitted to surface plate 110. Vibrations having different vibration directions are transmitted as different tactile sensations to the fingers of a person's hand in contact with the surface plate 110. Further, by combining two types of vibrations having different vibration directions, it is also possible to convey different tactile sensations.

  In the present embodiment, the vibration generating element 100 has, for example, a vibration frequency in the X1-X2 direction of 160 Hz, a vibration frequency in the Z1-Z2 direction of 320 Hz, and a vibration frequency in the X1-X2 direction. The frequency of vibration in the Z1-Z2 direction is different. In the present embodiment, two vibration generating elements 100 are provided, but the frequencies of the two vibration generating elements 100 may be different. For example, one vibration generating element 100 has a vibration frequency in the X1-X2 direction of 160 Hz, a vibration frequency in the Z1-Z2 direction is 320 Hz, and the other vibration generating element 100 has a vibration in the X1-X2 direction. May be 100 Hz, and the vibration frequency in the Z1-Z2 direction may be 200 Hz. In this way, by changing the frequency of vibration of the two vibration generating elements 100, various tactile sensations can be generated when a finger or the like of a human hand touches.
