[0028] Hereinafter, embodiments of the present technology will be described with reference to the drawings.

[0029] First Embodiment <Overall structure and structure of each part> Fig. 1 is a diagram illustrating a vibration presentation device 10 according to a first embodiment of the present technology as viewed from below. Fig. 2 is a cross-sectional view taken along line A-A' in Fig. 1, illustrating the vibration presentation device 10 as viewed from the side.

[0030] Fig. 3 is a view of a part of the vibration presentation device 10 seen from below. Fig. 4 is a view of a part of the vibration presentation device 10 seen from the side. Fig. 5 is a view of the frame 4 of the vibration presentation device 10 seen from below. Fig. 6 is a view of the frame 4 of the vibration presentation device 10 seen from the side.

[0031] The vibration presentation device 10 is installed and used in various places, such as theme parks, amusement parks, game centers, movie theaters, etc. The vibration presentation device 10 vibrates in response to various images displayed by a projector, a television device, an AR (Augmented Reality) or a VR (Virtual Reality) device, etc., and sounds output together with the images.

[0032] For example, the vibration presentation device 10 vibrates along with the image and sound of an explosion. By vibrating the vibration presentation device 10 in response to the image and sound, the vibration presentation device 10 can give the user a sense of realism and immersion.

[0033] The vibration presentation device 10 may be a device of a type that is used while the user is standing on the base unit 1, or may be a device of a type that is used while the user is sitting on the base unit 1. In the case of the vibration presentation device 10 of a type that is used while sitting, the vibration presentation device 10 may be configured in the shape of a chair.

[0034] As shown in Figures 1 to 6, the vibration presentation device 10 includes a base unit 1, three vibration units 2 provided on the underside of the base unit 1, four locking members 3 provided on the underside of the base unit 1, and a frame 4 that supports the base unit 1 from below.

[0035] The vibration presentation device 10 also includes a first buffer unit 5 interposed between the base unit 1 and the frame 4, and eight second buffer units 6 interposed between the frame 4 and the locking member 3. A handrail or the like that the user can grasp with their hands may be provided on the upper side of the base unit 1.

[0036] In the following description, when the three vibration parts 2 need to be particularly distinguished, they will be called the first vibration part 2a, the second vibration part 2b, and the third vibration part 2c. On the other hand, when the three vibration parts 2 are not particularly distinguished, they will be simply called vibration parts 2.

[0037] "Base part 1" The base unit 1 is configured so that a user can ride on it. Here, when a user "rides" on the base unit 1, it includes the user standing on the base unit 1 and positioning their entire body on the base unit 1, and it also includes the user sitting on the base unit 1 and positioning their entire body or part of their body on the base unit 1. In other words, the meaning of "ride" includes the meaning of "sit."

[0038] The base unit 1 is configured in a plate shape and has a rectangular shape in a plan view. The size of the base unit 1 may be, for example, large enough for one user to ride on it, or large enough for multiple users to ride on it. The size of the base unit 1 can be changed as appropriate depending on its use.

[0039] The base portion 1 is made of various materials such as metal, resin, wood, etc. Similarly, the locking member 3 and the frame 4 are made of various materials such as metal, resin, wood, etc.

[0040] In the example shown in the figure, the base portion 1 has a rectangular shape when viewed from above, but this shape may be a polygon other than a rectangle, a circle, etc., and the shape of the base portion 1 is not particularly limited.

[0041] "Vibration part 2" The vibrating section 2 includes a first vibrating section 2a, a second vibrating section 2b, and a third vibrating section 2c. The first vibrating section 2a is provided on the underside of the base section 1 at a position corresponding to the center of gravity of the base section 1. On the other hand, the second vibrating section 2b and the third vibrating section 2c are provided on the underside of the base section 1 at positions away from the center of gravity of the base section 1. Specifically, the second vibrating section 2b and the third vibrating section 2c are provided on opposite sides of the center of gravity of the base section 1.

[0042] The first vibrating portion 2a has a first vibration characteristic, and the second vibrating portion 2b and the third vibrating portion 2c have a second vibration characteristic that is different from the first vibration characteristic. In other words, the vibration characteristic of the first vibrating portion 2a is different from the vibration characteristics of the second vibrating portion 2b and the third vibrating portion 2c, and the vibration characteristic of the second vibrating portion 2b is the same as the vibration characteristic of the third vibrating portion 2c.

[0043] Here, the vibration characteristics of the vibration unit 2 refer to the characteristics of the "frequency," "amplitude," or "intensity" of the vibration that can be output by the vibration unit 2, and different vibration characteristics mean that the characteristics of the "frequency," "amplitude," or "intensity" of the vibration that can be output by the vibration unit 2 are different.

[0044] In the following description, the vibration characteristics are explained in terms of different frequency characteristics. Note that the term "frequency" used in the following description of the vibration characteristics of the vibration unit 2 can be read as "amplitude" or "intensity."

[0045] In the first embodiment, the first vibrating portion 2a has a first frequency characteristic, and the second vibrating portion 2b and the third vibrating portion 2c have a second frequency characteristic that is different from the first frequency characteristic.

[0046] The first vibrating part 2a has a relatively low frequency characteristic as a first frequency characteristic, and the second vibrating part 2b and the third vibrating part 2c have a relatively high frequency characteristic as a second frequency characteristic. For example, an actuator having a frequency characteristic of 10 Hz to 200 Hz (which can be changed as appropriate) is used as the first vibrating part 2a, and for example, an actuator having a frequency characteristic of 50 Hz to 500 Hz (which can be changed as appropriate) is used as the second vibrating part 2b and the third vibrating part 2c.

[0047] The high and low frequency characteristics may be reversed, i.e., the first vibrating part 2a may have a relatively high frequency characteristic as the first frequency characteristic, and the second vibrating part 2b and the third vibrating part 2c may have a relatively low frequency characteristic as the second frequency characteristic.

[0048] Furthermore, the first vibrating part 2a is vibrated in a first vibration direction, and the second vibrating part 2b and the third vibrating part 2c are vibrated in a second vibration direction different from the first vibration direction. In other words, the vibration direction of the first vibrating part 2a is different from the vibration direction of the second vibrating part 2b and the third vibrating part 2c, and the vibration direction of the second vibrating part 2b is the same as the vibration direction of the third vibrating part 2c.

[0049] In the first embodiment, the first vibration direction and the second vibration direction are perpendicular to each other. Specifically, the first vibration direction of the first vibrating part 2a is the vertical direction (Z-axis direction: direction perpendicular to the upper and lower surfaces of the base part 1). On the other hand, the second vibration directions of the second vibrating part 2b and the third vibrating part 2c are the horizontal direction (direction in the XY plane: direction parallel to the upper and lower surfaces of the base part 1).

[0050] 7 is a diagram showing the second vibration direction of the second vibrating portion 2b and the third vibrating portion 2c. As shown in FIG. 7, the second vibration direction of the second vibrating portion 2b and the third vibrating portion 2c is a direction in a horizontal plane. The second vibration direction is a direction perpendicular to the line (see dashed line) connecting the center of gravity of the base portion 1 (see x mark) and the second vibrating portion 2b and the third vibrating portion 2c. The second vibrating portion 2b and the third vibrating portion 2c are driven in opposite phases.

[0051] As shown in Figure 7, the second vibrating part 2b and the third vibrating part 2c are driven in opposite phases to each other, so that the second vibrating part 2b and the third vibrating part 2c can rotate the base part 1 around a vertical axis (Z axis).

[0052] The second vibrating part 2b and the third vibrating part 2c generate a rotation moment in the vertical direction (Z-axis direction) passing through the position of the center of gravity (see the X mark in Figure 7) of the base part 1. The first vibrating part 2a is placed at a position corresponding to this rotation moment so that its vibration direction coincides with the direction of the rotation moment.

[0053] The second vibrating section 2b and the third vibrating section 2c are typically driven simultaneously at the same timing. The first vibrating section 2a may be driven at the same timing as the second vibrating section 2b and the third vibrating section 2c, or may be driven at a timing different from the timing at which the second vibrating section 2b and the third vibrating section 2c are driven.

[0054] "Locking member 3" The locking member 3 is formed in a quadrangular prism shape and is provided so as to extend vertically from the underside of the base part 1. The locking members 4 are fixed at positions corresponding to the four corners of the base part 1 and slightly inward from the corners.

[0055] In the example shown in the figure, the shape of the locking member 3 is a rectangular prism, but this shape may also be a cylindrical shape or a polygonal prism shape other than a rectangular shape, and the shape of the locking member 3 is not particularly limited.

[0056] The locking member 3 is locked by the inner peripheral surface of the frame 4, thereby restricting horizontal movement. This prevents the base unit 1 from shifting sideways from the frame 4. In the first embodiment, the base unit 1 rotates around a vertical axis by the second vibrating unit 2b and the third vibrating unit 2c, so the base unit 1 is prone to shifting sideways by a relatively large amount relative to the frame 4. Therefore, using the locking member 3 to prevent lateral shifting is particularly effective.

[0057] "Frame 4" The frame 4 is formed in a rectangular frame shape in a plan view, and is approximately the same size in the horizontal direction as the base part 1. The frame 4 is disposed below the base part 1 and is capable of supporting the base part 1 from below. The frame 4 also surrounds the four locking members 3 in the circumferential direction, and its inner peripheral surface is capable of restricting horizontal movement of the four locking members 3.

[0058] In the example shown in the figure, the shape of the frame 4 is rectangular in a plan view, but this shape may also be circular or a polygon other than a square, and the shape of the frame 4 is not particularly limited.

[0059] "First buffer section 5" The first buffer section 5 is provided between the lower surface (outer periphery) of the base section 1 and the upper surface of the frame 4. The first buffer section 5 is provided around the entire periphery of the upper surface of the frame 4. Note that the first buffer section 5 may be provided so as to be scattered along the entire periphery of the upper surface of the frame 4.

[0060] The first buffer section 5 is made of a material having a certain elasticity, such as rubber, gel (for example, Alpha Gel), etc. Similarly, the second buffer section 6 is made of a material having a certain elasticity, such as rubber, gel, etc.

[0061] The first buffering section 5 is capable of reducing the attenuation of vibrations in the base section 1. Furthermore, by interposing the first buffering section 5 between the base section 1 and the frame 4, the base section 1 is able to move to a certain extent relative to the frame 4 (such as rotate around the Z axis).

[0062] "Second buffer section 6" The second buffer sections 6 are provided between the outer peripheral surface of the locking member 3 and the inner peripheral surface of the frame 4. Specifically, the second buffer sections 6 are provided between two of the four surfaces on the outer periphery of the locking member 3 that face the inner peripheral surface of the frame 4 and the inner peripheral surface of the frame 4. Therefore, two second buffer sections 6 are provided for each of the four locking members 3, for a total of eight (=4×2) second buffer sections 6.

[0063] The second buffer section 6 can prevent the locking member 3 from colliding with the frame 4 and generating a collision sound. Furthermore, by interposing the second buffer section 6 between the locking member 3 and the frame 4, the base section 1 can move to a certain extent relative to the frame 4 (such as rotate around the Z axis).

[0064] "Control device" The first vibration unit 2a, the second vibration unit 2b, and the third vibration unit 2c are electrically connected to a control device (not shown), and their driving is controlled by the control device. The control device may be a device dedicated to the vibration presentation device 10, or may be a general-purpose device such as a PC (Personal Computer).

[0065] The control device includes a control unit, a storage unit, etc. The control unit is, for example, a CPU (Central Processing Unit) or the like, and executes various calculations based on various programs stored in the storage unit, and controls the driving of the first vibration unit 2a, the second vibration unit 2b, and the third vibration unit 2c.

[0066] The storage unit includes a non-volatile memory for storing various programs and various data required for processing by the control unit, and a volatile memory used as a work area for the control unit. Note that the various programs may be read from a portable recording medium such as an optical disk or semiconductor memory, or may be downloaded from a server device on a network.

[0067] <Rotation around the vertical axis of the base part 1> In the first embodiment, the second vibrating unit 2b and the third vibrating unit 2c rotate the base unit 1 around a vertical axis to vibrate the base unit 1. The conditions under which vibration occurs due to rotation of the base unit 1 around the vertical axis will be described.

[0068] First, a description will be given of a case where only the second vibrating part 2b of the second vibrating part 2b and the third vibrating part 2c rotates the base part 1 about an axis in the vertical direction to vibrate the base part 1. Fig. 8 is a diagram showing an example of a case where only the second vibrating part 2b rotates the base part 1 about an axis in the vertical direction to vibrate the base part 1.

[0069] Condition 1: The second vibration direction of the second vibrating section 2b includes a horizontal component (a direction within the XY plane).

[0070] If the second vibration direction of the second vibrating part 2b does not include a horizontal component, the base part 1 does not rotate around the vertical axis (Z axis). In the first embodiment, the second vibration direction of the second vibrating part 2b includes only a horizontal component and does not include a vertical component.

[0071] Condition 2: The second vibrating part 2b is arranged at a position away from the center of gravity of the base part 1 (see the x mark in FIG. 8).

[0072] Even if the second vibration direction of second vibrating unit 2b includes a horizontal component, if second vibrating unit 2b is disposed at the center of gravity of base unit 1, base unit 1 will not rotate around a vertical axis. Figure 9 is a diagram showing the state when second vibrating unit 2b is disposed at the center of gravity of base unit 1. As shown in Figure 9, when second vibrating unit 2b is disposed at the center of gravity of base unit 1, base unit 1 will not rotate but will vibrate parallel to the second vibration direction of second vibrating unit 2b.

[0073] Condition 3: The second vibration direction of the second vibrating part 2b is not parallel to the line (see the dashed line in Figure 8) connecting the center of gravity of the base part 1 and the second vibrating part 2b (center of vibration).

[0074] Even if conditions 1 and 2 are satisfied, if the vibration direction of the second vibrating part 2b is parallel to the line connecting the center of gravity of the base part 1 and the second vibrating part 2b, the base part 1 will not rotate around a vertical axis.

[0075] Fig. 10 is a diagram showing a state when the second vibration direction of the second vibrating part 2b is parallel to the line (see dashed dotted line) connecting the center of gravity of the base part 1 and the second vibrating part 2. As shown in Fig. 10, when the second vibration direction of the second vibrating part 2b is parallel to the line (see dashed dotted line) connecting the center of gravity of the base part 1 and the second vibrating part 2b, the base part 1 does not rotate but vibrates parallel to the second vibration direction of the second vibrating part 2b.

[0076] Regarding condition 3, when the second vibration direction of the second vibrating part 2b is perpendicular to the line connecting the center of gravity of the base part 1 and the second vibrating part 2b (center of vibration), the base part 1 can be rotated most efficiently (see FIG. 8). For this reason, in the first embodiment, the second vibration direction of the second vibrating part 2b is perpendicular to the line connecting the center of gravity of the base part 1 and the second vibrating part 2b (see FIG. 7).

[0077] Next, a description will be given of a case where a third vibration unit 2c is further added to the vibration presentation device 10. The position and vibration direction of the third vibration unit 2c are also set so as to satisfy conditions 1, 2, and 3.

[0078] The third vibrating part 2c may basically be arranged in any way as long as its position and vibration direction are set so as to satisfy conditions 1, 2, and 3 (care must be taken with the phase of the drive of the second vibrating part 2b and the third vibration so that the rotational components of the second vibrating part 2b and the third vibrating part 2c do not cancel each other out).

[0079] On the other hand, in the first embodiment, the position and vibration direction of the vibration part 2 are set so that the third vibration part 2c, together with the second vibration part 2b, can most efficiently rotate the base part 1 around a vertical axis to vibrate the base part 1.

[0080] 7, in the first embodiment, in order to most efficiently rotate the base unit 1 around an axis in the vertical direction, the third vibrating unit 2c is disposed on the opposite side of the center of gravity of the base unit 1 from the second vibrating unit 2b. In addition, in the first embodiment, in order to most efficiently rotate the base unit 1 around an axis in the vertical direction, the vibration direction of the third vibrating unit 2c is set to the same direction as the second vibration direction of the second vibrating unit 2b, and the vibration direction of the third vibrating unit 2c is set to be perpendicular to the line connecting the center of gravity of the base unit 1 and the third vibrating unit 2c (center of vibration).

[0081] In this case, when the second vibrating portion 2b and the third vibrating portion 2c are driven in the same phase, the rotational components of the second vibrating portion 2b and the third vibrating portion 2c cancel each other out. For this reason, in the first embodiment, the second vibrating portion 2b and the third vibrating portion 2c are driven in opposite phases. When the second vibrating portion 2b and the third vibrating portion 2c are driven in the same phase, the base portion 1 does not rotate but vibrates in a direction parallel to the second vibration direction of the second vibrating portion 2b and the third vibrating portion 2c.

[0082] Note that the various conditions described here are conditions for rotating the base unit 1 around a vertical axis only, and therefore, it is not intended that the position, vibration direction, and phase of the vibration unit 2 should not be set so as to deviate from the various conditions in this technology.

[0083] For example, as shown in Fig. 9, the second vibrating part 2b may be disposed at a position corresponding to the center of gravity of the base part 1 (for example, the second vibrating part 2b may be disposed either above or below the first vibrating part 2a). Also, as shown in Fig. 10, the vibration direction of the second vibrating part 2b may be set so that the vibration direction is parallel to a line connecting the center of gravity of the base part 1 and the second vibrating part 2b. Also, in Fig. 7, the second vibrating part 2b and the third vibrating part 2c may be driven in the same phase.

[0084] <Effect, etc.> The vibration presentation device 10 according to the first embodiment uses two types of vibration units 2 (the first vibration unit 2a, and the second and third vibration units 2b and 2c) with different frequency characteristics, and therefore can provide the user with a variety of vibration experiences. That is, in the first embodiment, it is possible to present to the user vibrations over a wide band that cannot be reproduced when there is only one vibration unit 2 or when there are multiple vibration units 2 but the frequency characteristics of these vibration units 2 are the same.

[0085] In the vibration presentation device 10 according to the first embodiment, the first vibration direction of the first vibration unit 2a and the second vibration direction of the second vibration unit 2b and the third vibration unit 2c are different directions, and in particular, the first vibration direction and the second vibration direction are perpendicular to each other. This makes it possible to present vibrations in two perpendicular directions to the user.

[0086] In the vibration presentation device 10 according to the first embodiment, the first vibration direction of the first vibration unit 2a is the vertical direction, and the second vibration directions of the second vibration unit 2b and the third vibration unit 2c are the directions in the horizontal plane, thereby making it possible to present vibrations in two directions, the vertical direction and the horizontal direction.

[0087] Furthermore, in the first embodiment, the first vibrating part 2a is disposed at a position corresponding to the center of gravity of the base part 1, so that the first vibrating part 2a can efficiently vibrate the base part 1 in the vertical direction.

[0088] Furthermore, in the first embodiment, the second vibrating part 2b is disposed at a position displaced from the center of gravity of the base part 1, and the second vibration direction of the second vibrating part 2b is set to a direction non-parallel to the line connecting the center of gravity of the base part 1 and the second vibrating part 2b. This allows the base part 1 to vibrate by rotating it around an axis in the vertical direction by the second vibrating part 2b.

[0089] In the first embodiment, the second vibration direction of the second vibrating part 2b is set to a direction perpendicular to the line connecting the center of gravity of the base part 1 and the second vibrating part 2b. This allows the second vibrating part 2b to efficiently rotate the base part 1 around an axis in the vertical direction.

[0090] In the first embodiment, the third vibrating part 2c is disposed on the opposite side of the center of gravity of the base part 1 from the second vibrating part 2b. The vibration direction of the third vibrating part 2c is the same as the second vibration direction of the second vibrating part 2b, and the third vibrating part 2c is driven in the opposite phase to the second vibrating part 2b. This allows the third vibrating part 2c, together with the second vibrating part 2b, to efficiently rotate the base part 1 around an axis in the vertical direction, causing the base part 1 to vibrate.

[0091] The first embodiment also has the advantage of being able to reduce vibration unevenness. Fig. 11 is a diagram showing a vibration presentation device 20 according to a comparative example, illustrating an example of a case in which vibration unevenness occurs. Unlike the vibration presentation device 10 according to the first embodiment, the vibration presentation device 20 according to the comparative example does not include the second vibrating unit 2b, the third vibrating unit 2c, the locking member 3, and the second buffer unit 6.

[0092] 11, in the vibration presentation device 20 according to the comparative example, when the first vibrating unit 2a vibrates, the outer periphery of the base unit 1 becomes a node of the vibration, so the vibration is large near the center of the base unit 1 and small at positions closer to the outer periphery of the base unit 1. If there are users standing near the center of the base unit 1 and users standing at positions closer to the outer periphery of the base unit 1, the magnitude of the vibration presented to each user will differ.

[0093] On the other hand, in the vibration presentation device 10 according to the first embodiment, the second vibration unit 2b and the third vibration unit 2c can rotate the base unit 1 around an axis in the vertical direction to vibrate the base unit 1 (see FIG. 7). Therefore, in the vibration presentation device 10 according to the first embodiment, the second vibration unit 2b and the third vibration unit 2c can uniformly vibrate the base unit 1 even at positions near the periphery.

[0094] That is, if the first vibrating unit 2a, the second vibrating unit 2b, and the third vibrating unit 2c are driven simultaneously, the first vibrating unit 2a vibrates the vicinity of the center of the base unit 1, and the second vibrating unit 2b and the third vibrating unit 2c vibrate the outer periphery of the base unit 1, resulting in uniform vibration throughout the base unit 1. In this case, if there are users standing near the center of the base unit 1 and users standing closer to the periphery of the base unit 1, the magnitude of the vibration presented to each user can be made uniform.

[0095] Second Embodiment Next, a second embodiment of the present technology will be described. In the descriptions of the second and subsequent embodiments, parts having the same configurations and functions as those in the first embodiment described above will be denoted by the same reference numerals, and descriptions thereof will be omitted or simplified.

[0096] Fig. 12 is a diagram of a vibration presentation device 11 according to the second embodiment as seen from above. Note that in Fig. 12, parts other than the base unit 1, the first vibrating unit 2a, the second vibrating unit 2b, and the third vibrating unit 2c are omitted from the illustration. Note that in Figs. 13 to 16 described later, parts other than the respective parts are also omitted from the illustration.

[0097] In the second embodiment, as in the first embodiment, the first vibrating part 2a is disposed at the center of gravity of the base part 1, and the second vibrating part 2b and the third vibrating part 2c are disposed at positions away from the center of gravity of the base part 1, on opposite sides of the center of gravity of the base part 1. Also, in the second embodiment, as in the first embodiment, the first vibration direction of the first vibrating part 2a is the vertical direction, and the second vibration directions of the second vibrating part 2b and the third vibrating part 2c are the directions in the horizontal plane.

[0098] On the other hand, in the first embodiment, the second vibration direction of the second vibrating part 2b and the third vibrating part 2c was set to a direction non-parallel (perpendicular) to the line connecting the center of gravity of the base part 1 and the second vibrating part 2b and the third vibrating part 2c (center of vibration) (see Figure 7).

[0099] In contrast, in the second embodiment, as shown in FIG. 12, the second vibration direction in the second vibrating part 2b and the third vibrating part 2c is parallel to the line connecting the center of gravity of the base part 1 and the second vibrating part 2b and the third vibrating part 2c (center of vibration).

[0100] In the first embodiment, the second vibrating portion 2b and the third vibrating portion 2c are driven in opposite phases, whereas in the second embodiment, the second vibrating portion 2b and the third vibrating portion 2c are driven in the same phase because the vibrations of the second vibrating portion 2b and the third vibrating portion 2c cancel each other out if the second vibrating portion 2b and the third vibrating portion 2c are driven in opposite phases.

[0101] In the second embodiment, the second vibrating part 2b is disposed at a position offset from the center of gravity of the base part 1, and the second vibration direction of the second vibrating part 2b is parallel to a line connecting the center of gravity of the base part 1 and the second vibrating part 2b. Therefore, the second vibrating part 2b can efficiently vibrate the base part 1 in the second vibration direction.

[0102] In the second embodiment, the third vibrating part 2c is disposed on the opposite side of the center of gravity of the base part 1 from the second vibrating part 2b, and the vibration direction of the third vibrating part 2c is the same as the second vibration direction of the second vibrating part 2b. The third vibrating part 2c is driven in the same phase as the second vibrating part 2b. This allows the third vibrating part 2c to efficiently vibrate the base part 1 in the second vibration direction together with the second vibrating part 2b.

[0103] Furthermore, in the second embodiment, it is possible to reduce vibration unevenness in relation to the vibration of the base portion 1 in the second vibration direction by the second vibrating portion 2b and the third vibrating portion 2c. In other words, in the second embodiment, when the second vibrating portion 2b and the third vibrating portion 2c are driven, the entire base portion 1 vibrates uniformly in the second vibration direction, thereby reducing vibration unevenness.

[0104] Third Embodiment Next, a third embodiment of the present technology will be described. Fig. 13 is a diagram showing a vibration presentation device 12 according to the third embodiment as viewed from the side.

[0105] In the third embodiment, as in the above-described embodiments, the first vibrating part 2a is disposed at the center of gravity of the base part 1, and the second vibrating part 2b and the third vibrating part 2c are disposed at positions away from the base part 1, on opposite sides of the center of gravity of the base part 1. Also, in the third embodiment, as in the above-described embodiments, the first vibration direction of the first vibrating part 2a is the vertical direction.

[0106] Meanwhile, in each of the above-described embodiments, the second vibration direction of the second vibrating portion 2b and the third vibrating portion 2c is a direction in a horizontal plane. In contrast, in the third embodiment, as shown in Fig. 13, the second vibration direction of the second vibrating portion 2b and the third vibrating portion 2c is a vertical direction (the same direction as the first vibration direction).

[0107] Furthermore, the second vibrating section 2b and the third vibrating section 2c are driven in opposite phases to each other, and as a result of the second vibrating section 2b and the third vibrating section 2c being driven in opposite phases to each other, the second vibrating section 2b and the third vibrating section 2c can rotate the base section 1 around a horizontal axis (the Y-axis in this example).

[0108] The second vibrating part 2b and the third vibrating part 2c generate a rotation moment in the horizontal direction (Y-axis direction) passing through the position of the center of gravity (see the x mark) of the base part 1. The first vibrating part 2a is placed at a position corresponding to the rotation moment so that its vibration direction is perpendicular to the direction of the rotation moment.

[0109] In the third embodiment, the second vibrating unit 2b and the third vibrating unit 2c rotate the base unit 1 around a horizontal axis to vibrate the base unit 1. The conditions under which vibration occurs due to rotation of the base unit 1 around the horizontal axis will be described.

[0110] First, a case will be described in which, of the second vibrating part 2b and the third vibrating part 2c, only the second vibrating part 2b rotates the base part 1 about a horizontal axis to vibrate the base part 1.

[0111] Condition 1: The second vibration direction of the second vibrating portion 2b includes a component in the vertical direction (direction within a plane).

[0112] If the second vibration direction of the second vibrating part 2b does not include a vertical component, the base part 1 does not rotate around a horizontal axis. In the third embodiment, the second vibration direction of the second vibrating part 2b includes only a vertical component and does not include a horizontal component.

[0113] Condition 2: The second vibrating part 2b is arranged at a position away from the center of gravity of the base part 1 (see the x mark).

[0114] Even if the second vibration direction of the second vibrating part 2b includes a vertical component, if the second vibrating part 2b is placed at the center of gravity of the base part 1, the base part 1 will not rotate around a horizontal axis.

[0115] If the second vibrating unit 2b satisfies conditions 1 and 2, the base unit 1 can be rotated about a horizontal axis by the second vibrating unit 2b alone to vibrate the base unit 1. Note that, when the base unit 1 is rotated about a vertical axis as in the first embodiment, the third condition exists, but when the base unit 1 is rotated about a horizontal axis as in the third embodiment, the third condition does not exist.

[0116] Next, a description will be given of a case where a third vibration unit 2c is further added to the vibration presentation device 12. The position and vibration direction of the third vibration unit 2c are also set so as to satisfy the conditions 1 and 2.

[0117] The third vibrating part 2c can basically be arranged in any way as long as its position and vibration direction are set so as to satisfy conditions 1 and 2 (care must be taken with the phase of the drive of the second vibrating part 2b and the third vibration so that the rotational components of the second vibrating part 2b and the third vibrating part 2c do not cancel each other out).

[0118] On the other hand, in the third embodiment, the position and vibration direction of the third vibration part 2c are set so that the third vibration part 2c, together with the second vibration part 2b, can most efficiently rotate the base part 1 around a horizontal axis to vibrate the base part 1.

[0119] 13, in order to most efficiently rotate the base portion 1 about an axis in the horizontal direction, in the third embodiment, the third vibrating portion 2c is disposed on the opposite side of the center of gravity of the base portion 1 from the second vibrating portion 2b. Also, in order to most efficiently rotate the base portion 1 about an axis in the horizontal direction, in the third embodiment, the vibration direction of the third vibrating portion 2c is set to the same direction as the second vibration direction of the second vibrating portion 2b.

[0120] In this case, if the second vibrating portion 2b and the third vibrating portion 2c are driven in the same phase, the rotational components of the second vibrating portion 2b and the third vibrating portion 2c will cancel each other out. For this reason, in the third embodiment, the second vibrating portion 2b and the third vibrating portion 2c are driven in opposite phases. Note that if the second vibrating portion 2b and the third vibrating portion 2c are driven in the same phase, the base portion 1 will vibrate vertically without rotating.

[0121] Note that the various conditions described here are merely conditions for rotating the base unit 1 around a horizontal axis. Therefore, it is not intended that the position, vibration direction, and phase of the vibration unit 2 should not be set so as to deviate from the various conditions in this technology. For example, in FIG. 13, the second vibration unit 2b and the third vibration unit 2c may be driven in the same phase.

[0122] In the third embodiment, the second vibrating part 2b is disposed at a position away from the center of gravity of the base part 1, and the second vibration direction of the second vibrating part 2b is set to the vertical direction. Therefore, the second vibrating part 2b can rotate the base part 1 efficiently around an axis in the horizontal direction, causing the base part 1 to vibrate.

[0123] In the third embodiment, the third vibrating unit 2c is disposed on the opposite side of the center of gravity of the base unit 1 from the second vibrating unit 2b, and the vibration direction of the third vibrating unit 2c is the same as the second vibration direction of the second vibrating unit 2b. The third vibrating unit 2c is driven in the opposite phase to the second vibrating unit 2b. This allows the third vibrating unit 2c, together with the second vibrating unit 2b, to efficiently rotate the base unit 1 around a horizontal axis and vibrate the base unit 1.

[0124] Furthermore, the third embodiment also reduces uneven vibration in the base part 1. That is, if the first vibrating part 2a, the second vibrating part 2b, and the third vibrating part 2c are driven simultaneously, the first vibrating part 2a vibrates the center of the base part 1, and the second vibrating part 2b and the third vibrating part 2c vibrate the outer periphery of the base part 1, so that the vibration becomes uniform over the entire base part 1.

[0125] Fourth Embodiment Next, a fourth embodiment of the present technology will be described. Fig. 14 is a diagram showing a vibration presentation device 13 according to the fourth embodiment as viewed from the side.

[0126] In the fourth embodiment, as in the above-described embodiments, the first vibrating part 2a is positioned corresponding to the center of gravity of the base part 1, and the first vibration direction of the first vibrating part 2a is the vertical direction.

[0127] Meanwhile, in each of the above-described embodiments, the second vibrating part 2b is disposed at a position away from the center of gravity of the base part 1, but in the fourth embodiment, the second vibrating part 2b is disposed below the first vibrating part 2a at a position corresponding to the center of gravity of the base part 1. The second vibration direction of the second vibrating part 2b is set to the vertical direction (the same direction as the first vibration direction).

[0128] Moreover, in the fourth embodiment, unlike the above-described embodiments, the third vibrating portion 2c is not provided.

[0129] The first vibrating section 2a and the second vibrating section 2b may be driven simultaneously at the same timing, or may be driven individually at different timings.

[0130] When the first vibrating part 2a and the second vibrating part 2b are driven simultaneously at the same timing, if the first vibrating part 2a and the second vibrating part 2b are driven in opposite phases, the vibrations of the first vibrating part 2a and the second vibrating part 2b will cancel each other out. Therefore, in this case, the first vibrating part 2a and the second vibrating part 2b are driven in the same phase.

[0131] In addition to the first vibrating portion 2a and the second vibrating portion 2b in the fourth embodiment, the second vibrating portion 2b and the third vibrating portion 2c described in the above embodiments may be further provided.

[0132] Fifth Embodiment In the fifth embodiment, a structure for reducing noise caused by vibration of the base portion 1 will be described.

[0133] The base unit 1 has a relatively large area so that a user can stand on it (sit on it), and therefore, vibration of the base unit 1 (especially in the vertical direction) can generate a relatively loud noise. This noise can become louder if the base unit 1 is vibrated strongly, and can become a problem as noise. In the fifth embodiment, a structure for reducing such noise will be described.

[0134] Fig. 15 is a diagram showing the base part 1 of the vibration presentation device 14 according to the fifth embodiment as seen from above. Fig. 16 is a diagram showing the base part 1 of the vibration presentation device 14 according to the fifth embodiment as seen from the side.

[0135] In the vibration presentation device 14 according to the fifth embodiment, a plurality of holes 9 penetrating in the vertical direction are provided in the base unit 1, and the base unit 1 has a porous structure. Typically, the plurality of holes 9 are provided in at least the peripheral region excluding the region near the center in the horizontal direction of the base unit 1. Note that the plurality of holes 9 may also be provided in the region near the center in the horizontal direction of the base unit 1.

[0136] 15 and 16, the first vibrating portion 2a, the second vibrating portion 2b, and the third vibrating portion 2c have the same configurations as those in the first embodiment. On the other hand, the first vibrating portion 2a, the second vibrating portion 2b, and the third vibrating portion 2c may have any of the configurations described in the above-mentioned embodiments.

[0137] 15 and 16, the shape of the hole 9 is circular in plan view, but the shape of the hole 9 in plan view is not limited to circular and may be any shape. Fig. 17 is a diagram showing examples of the shape of the hole 9. Fig. 17 shows, from the left, examples of when the shape of the hole 9 is a circle, a square, a cross, a five-pointed star, and a seven-pointed star.

[0138] 15 and 16 show an example in which the holes 9 are provided parallel to the vertical direction, but the shape of the holes 9 in the vertical direction is not limited to this. Fig. 18 is a diagram showing examples of the shape of the holes 9 in the vertical direction. Fig. 18 shows examples in which, from the top, the holes 9 have a shape parallel to the vertical direction, a shape that gradually narrows toward the bottom, a shape that gradually widens toward the bottom, and a shape that gradually narrows toward the bottom and then gradually widens.

[0139] In the fifth embodiment, when the base portion 1 vibrates (particularly in the vertical direction), the air in the space surrounded by the base portion 1 and the frame 4 escapes above the base portion 1 through the multiple holes 9 in the base portion 1. This reduces noise generated by the compression and expansion of the air in the space surrounded by the base portion 1 and the frame 4.

[0140] Furthermore, in the fifth embodiment, when the base portion 1 vibrates (particularly in the vertical direction), air in the space above the base portion 1 escapes below the base portion 1 through the multiple holes 9 in the base portion 1. This reduces noise that is generated when the vibrations of the base portion 1 propagate to the space above the base portion 1 when the base portion 1 vibrates.

[0141] Furthermore, in the fifth embodiment, a plurality of holes 9 are provided in at least the peripheral region in the horizontal direction. This reduces the weight of the peripheral region of the base unit 1, making it easier for the base unit 1 to rotate. In other words, in the case where the base unit 1 rotates around a vertical or horizontal axis by the vibration unit 2 (first and third embodiments), providing a plurality of holes 9 in the peripheral region of the base unit 1 not only reduces noise but also makes it easier for the base unit 1 to rotate.

[0142] Furthermore, in the fifth embodiment, even if the strength of the vibration is increased, noise is unlikely to occur, so that vibrations with high strength can be presented to the user.

[0143] As described above, the vibration presentation device is a device that vibrates in response to video and audio to give the user a sense of realism and immersion. Therefore, if the noise caused by the vibration is large, the noise may interfere with the audio that should be provided, and the user's sense of realism and immersion may be diminished.

[0144] On the other hand, in the fifth embodiment, noise caused by vibration can be reduced, so that the sound that should be provided can be provided to the user clearly, and the user can be given an appropriate sense of realism and immersion.

[0145] <Various Modifications of the Fifth Embodiment> Hereinafter, various modified examples of the structure for reducing noise caused by vibration of the base portion 1 will be described.

[0146] Wire mesh structure Fig. 19 is a diagram showing an example in which the base portion 1 has a wire mesh structure. In the example shown in Fig. 19, the entire base portion 1 has the wire mesh structure. On the other hand, the peripheral portion of the base portion 1, excluding the vicinity of the horizontal center, may have the wire mesh structure. Fig. 19 also shows an example in which the mesh has a rectangular shape. On the other hand, the mesh shape may be a honeycomb shape or the like, and is not particularly limited.

[0147] Even when the base part 1 has a wire mesh structure, air can pass through in the vertical direction, thereby reducing noise caused by vibration of the base part 1. Furthermore, when the base part 1 is configured to rotate, in addition to the soundproofing effect, it also has the effect of making the base part 1 easier to rotate.

[0148] "Open-cell structure" Fig. 20 is a diagram showing an example of a case where the base unit 1 has an open-cell structure. In the example shown in Fig. 20, the base unit 1 is formed from a material such as foam rubber or foam plastic with a relatively hard open-cell structure that is rigid enough to allow a user to stand on it. In the example shown in Fig. 20, the entire base unit 1 has an open-cell structure, but the peripheral portion of the base unit 1, excluding the vicinity of the horizontal center, may also have an open-cell structure.

[0149] Even when the base part 1 has an open-cell structure, air can pass through in the vertical direction, thereby reducing noise caused by vibration of the base part 1. Furthermore, when the base part 1 is configured to rotate, in addition to the soundproofing effect, it also has the effect of making the base part 1 easier to rotate.

[0150] A part of the base part 1 may be made of a relatively soft material with an open-cell structure (for example, sponge) such as foam rubber or foam plastic that has a rigidity that prevents a user from standing on it alone. In this case, the lower part of the base part 1 is made of a material with a certain level of rigidity or more (structures such as holes 9 may or may not be present), and the upper part of the base part 1 is made of a relatively soft material with an open-cell structure (for example, sponge).

[0151] The thickness of the relatively soft open-cell structure portion is made thicker than, for example, the vertical amplitude of the base portion 1. When the base portion 1 vibrates, the relatively soft open-cell structure portion absorbs the vibrations of the air above the base portion 1, thereby preventing noise from being generated.

[0152] The porous structure, wire mesh structure, and open-cell structure for allowing air to pass through in the vertical direction can be combined as appropriate.

[0153] Sixth Embodiment Next, a sixth embodiment of the present technology will be described. Fig. 21 is a diagram showing a vibration presentation device 15 according to the sixth embodiment as viewed from above. Fig. 22 is a cross-sectional view taken along line B-B' shown in Fig. 21, showing the vibration presentation device 15 as viewed from the side.

[0154] As shown in these figures, the vibration presentation device 15 according to the sixth embodiment includes a plurality of vibration units 16 arranged adjacent to each other in the horizontal direction. One vibration unit 16 corresponds to the vibration presentation device described in each of the above embodiments. In the examples shown in Fig. 21 and Fig. 22, the number of vibration units 16 is four, but the number of vibration units 16 is not particularly limited as long as it is two or more.

[0155] 21 and 22, the configuration of the vibration unit 16 (the configuration of the vibration section 2) is the same as that of the vibration presentation device 10 of the first embodiment. On the other hand, the configuration of the vibration unit 16 (the configuration of the vibration section 2) may be configured to correspond to any of the vibration presentation devices described in the above embodiments.

[0156] Each vibration unit 16 includes a base portion 1, three vibration portions 2, four locking members 3, a frame 4, a first buffer portion 5, and eight second buffer portions 6.

[0157] The vibration presentation device 15 further includes a third buffer section 7 provided between two opposing side surfaces of the base section 1 of adjacent vibration units 16. The third buffer section 7 is made of a member having a certain elasticity, such as rubber or gel (e.g., Alpha Gel).

[0158] 21 and 22, in the vibration presentation device 15, two side surfaces of the base unit 1 face each other at four locations, and two third buffer units 7 are provided at each of the four locations. Therefore, a total of eight third buffer units 7 are provided, with a 4x2 ratio. The number of third buffer units 7 can be changed as appropriate.

[0159] In the sixth embodiment, the third buffer section 7 is provided, which can prevent adjacent base sections 1 from colliding with each other and generating noise. Note that in the case of a configuration in which the base section 1 rotates and vibrates around a vertical axis as in the first embodiment, adjacent base sections 1 are more likely to collide with each other and generate noise, so providing the third buffer section 7 is particularly effective in such a configuration.

[0160] <<Various variations>> In the above description, the first vibration direction of the first vibrating unit 2a is the vertical direction. On the other hand, the first vibration direction of the first vibrating unit 2a may be a direction in a horizontal plane. Also, in the above description, the vibration presentation device includes three vibrating units 2 (other than the fourth embodiment). On the other hand, it is typically sufficient for the vibration presentation device to have at least two vibrating units 2 (the first vibrating unit 2a and the second vibrating unit 2b) with different vibration characteristics.
