(First embodiment of the present invention)
The vibration presenting apparatus 10 according to the first embodiment of the present invention includes a vibration panel 20 that presents vibration, a voice coil motor 100 as a vibration generating unit that applies vibration to the vibration panel 20, and the vibration panel 20. A supporting housing 30, a support portion 40 interposed between the vibration panel 20 and the housing 30 and compressed by a predetermined force, and a support portion 40 interposed between the vibration panel 20 and the housing 30 in parallel with the supporting portion 40. A damper 50 that applies a braking action to the vibration of the vibration panel 20, and a spring as a pressurizing unit that applies a predetermined force to the support 40 and the damper 50 and applies a compressive force to the support 40 and the damper 50. 60, a preload spring 70 for applying an elastic force toward the vibration panel 20 via the damper 50, and a guide provided on the housing side that supports the force by which the damper 50 is pressed toward the vibration panel 20 by the preload spring 70. Part 3 When having a damper 50 is configured to a state of being supported by the guide portion 32 is pushed to the vibrating panel 20 side by a predetermined force by the preload spring 70 as the initial position (initial state).

  In the above configuration, the damper 50 is not fixed on the vibration panel 20 side. Therefore, when vibration exceeding the amount of deflection of the damper 50 at the initial position is applied to the vibration panel 20, the damper 50 50 does not contribute to vibration damping. In addition, when the predetermined force by the preload spring 70 is exceeded due to vibration applied to the vibration panel 20, the preload spring 70 is mainly displaced, so that the damper 50 does not contribute to vibration attenuation. That is, the damper configuration has a damping characteristic (braking characteristic) symmetrical in both directions in the vicinity of the initial position. This makes it possible to suppress residual vibration while suppressing an increase in cost and size of the vibration presenting apparatus.

The vibration panel 20 can present vibration by being driven by a voice coil motor 100 as a drive source. For example, when the vibration panel 20 as the touch detection device is touched, the operator is notified of the touch by vibrating the vibration panel 20 in, for example, the B direction shown in FIG. In addition, tactile sensation can be presented by vibrating the vibration panel 20 in accordance with various operations.

  An attachment portion 22 is formed on the lower surface 20 b of the vibration panel 20, and the coil 110 of the voice coil motor 100 is attached and fixed to the attachment portion 22. As shown in FIGS. 1A and 1B, a locking hole 20 c for locking the hook portion of the spring 60 is formed in the corner portion 21 of the vibration panel 20. A pusher 23 for pressing the damper 50 downward is attached to the lower surface 20 b of the vibration panel 20. The pusher 23 is a rigid rod-shaped member such as resin or metal. Further, the lower surface 20b of the vibration panel 20 is a surface with which the end of the support portion 40 abuts.

Corresponding to the vibration panel 20, a locking hole 30 b for locking the hook portion of the spring 60 is formed in the corner portion 31. The upper portion 30a of the housing 30 is a surface with which the end portion of the support portion 40 abuts.

  As shown in FIG. 1 and the like, a guide portion 32 is provided on the upper portion 30 a of the housing 30 corresponding to the damper 50 and the preload spring 70. The guide portion 32 has a cylindrical shape for guiding the damper 50 and the preload spring 70 so as to be movable in the vertical direction, and accommodates the damper 50 and the preload spring 70 therein. The guide portion 32 has an upper wall portion 33, and the upper wall surface 33 a of the upper wall portion 33 supports a damper 50 that is pressed toward the vibration panel 20 by a preload spring 70 with a predetermined force.

(Supporting part 40)
The support part 40 is formed of an elastic member such as silicon rubber. As shown in FIGS. 1A and 1B, the support portion 40 has a rectangular frame shape, but is not limited thereto. Any shape that can support the vibration panel 20 interposed between the vibration panel 20 and the housing 30 may be used. As shown in FIG. 3 (a), the thickness of the support portion 40 (length in a direction which is interposed between the vibrating panel 20 and the housing 30) is Z ₁ in the natural length.

(Damper 50)
The damper 50 is formed of an elastic member such as rubber or synthetic resin. For example, any material having viscosity and elasticity and exhibiting a braking action against vibration such as butyl rubber may be used. Various elastic members marketed as viscoelastic dampers can be used.

In the present embodiment, as shown in FIG. 1A and the like, the spring 60 uses a tension coil spring. As shown in FIG. 3B, the spring 60 is composed of a coil portion formed by a tensile force and hook portions 60a and 60b formed at both ends thereof. The hook portions 60 a and 60 b are hooked and locked in the locking hole 20 c of the vibration panel 20 and the locking hole 30 b of the housing 30, respectively. Thereby, a tensile force is generated between the vibration panel 20 and the housing 30. Therefore, a compressive force can be applied to the support portion 40 and the damper 50 interposed between the vibration panel 20 and the housing 30.

In FIG. 2, the compression length Zd indicates the amount of displacement when compressed from the initial position, and is the load F ₀ and the spring coefficient K ₀ at the initial position. Incidentally, the spring coefficient K ₀ is smaller. As a result, the influence of the preload spring 70 on the vibration can be reduced, and the damping effect of the damper 50 can be applied only in a minute region near the stop position of the vibration panel 20 where the residual vibration occurs.

(Voice coil motor 100)

If the energization to the coil 110 is alternating current, the vibration will reciprocate in the B direction. Thereby, the vibration panel 20 to which the coil 110 is attached and fixed can vibrate in the B direction and present vibration. In addition, the vibration presentation to directions other than the B direction shown to Fig.1 (a) is also possible by the arrangement | positioning relationship between the coil 110 and the magnetic circuit 120.

That is, the preload spring 70 is compressed, the upper end portion 70 a is in contact with the damper 50, and the lower end portion 70 b is in contact with the upper portion 30 a of the housing 30. As a result, the damper 50 is pressed toward the vibration panel 20 with a predetermined force by the preload spring 70 and is supported by the guide portion 32 (upper wall portion 33, upper wall surface 33a). In this step, the lower end surface 23 a of the pusher 23 has not yet contacted the upper end portion 50 a of the damper 50.

Further, the support portion 40 is disposed at a predetermined position on the upper portion 30a of the housing 30 on which the voice coil motor 100 is placed and fixed. In this state, the support portion 40 is a natural length Z _1. That is, in the state illustrated in FIG. 3A, the upper end portion 40 a of the support portion 40 and the lower surface 20 b of the vibration panel 20 abut, but the support portion 40 is not compressed, and the lower surface 20 b of the vibration panel 20 and the housing 30 are not compressed. the distance between the upper 30a indicates the same state as natural length Z ₁ of the support portion 40.

  The lower end portion 40b of the support portion 40 may be fixed by being in contact with the upper portion 30a of the housing 30, or by adhesion or the like.

  In this state, the vibration panel 20 to which the coil 110 is attached and fixed is aligned with a predetermined position so that the upper end portion 40a of the support portion 40 and the lower surface 20b of the vibration panel 20 are in contact with each other. At this time, the spring 60 is not yet attached, and the lower end surface 23a of the pusher 23 and the upper end portion 50a of the damper 50 are not in contact with each other.

  As shown in FIG. 3B, the hooks 60 a and 60 b of the spring 60 are hooked on the locking holes 20 c of the vibration panel 20 and the locking holes 30 b of the housing 30 while pulling the spring 60 in the C direction. Lock. Thereby, the support part 40 interposed between the vibration panel 20 and the housing | casing 30 contacts, and receives a compressive force. FIG. 3B illustrates a state in the middle of pulling the spring 60 in the C direction.

State shown in FIG. 3 (c), is compressed support portion 40, the distance between the upper 30a of the lower surface 20b and the casing 30 of the vibration panel 20 shows a state of completion assembled it becomes a predetermined distance Z ₀ Yes. At this time, the upper end portion 40a of the support portion 40 may remain in contact with the lower surface 20b of the vibration panel 20, or may be fixed by adhesion or the like. Further, the lower end surface 23a of the pusher 23 and the upper end portion 50a of the damper 50 are in contact with each other, and the damper 50 is pressed downward by the pusher 23 and is deformed by a predetermined amount (Δ ₁ ).

  The vibration presenting apparatus 10 is vibrated by the voice coil motor 100 when the coil 110 is energized in the above-described assembly completion state.

FIG. 4 is a diagram illustrating a relationship between forces acting on each member at the initial position of the vibration presenting apparatus. As shown in FIG. 4, the tension force of the spring 60 is F ₁ , the extension force of the support portion 40 is F ₂ , the extension force of the preload spring 70 is F ₀ , and the upper wall portion 33 (upper wall surface 33 a) that acts on the damper 50. _Let the reaction force from be FR.

The formula for balance of forces acting on the damper 50 is as follows.
F ₁ −F ₂ + F _R = F ₀
Here, F ₁ -F ₂ is a force F by which the pusher 23 presses the damper 50 downward.
From the above equation, in the initial position, the force F pusher 23 pushes the damper 50 in a downward _direction, by setting the _{F 0/2,} the _F R ₌ F 0/2.

As described above, by setting the initial position (initial state), by the vibration, when the force pusher 23 downward to press the damper 50 is more than F _0/2 is pre-load spring 70 Deflection However, with a force within that range, the damper 50 mainly acts. That is, the damping action of the damper 50 is mainly performed at a small vibration width (Δ ₂ ) in the downward direction.

On the other hand, when the pusher 23 moves upward due to vibration, as described above, the lower end surface of the pusher 23 in the minute vibration width (Δ ₁ ) from the deformation amount (Δ ₁ ) of the damper 50 upward. 23a and the upper end portion 50a of the damper 50 remain in contact with each other. However, if the vibration width is larger than that, the lower end surface 23a of the pusher 23 and the upper end portion 50a of the damper 50 do not contact each other, and the damping action of the damper 50 does not work.

As described above, in the present embodiment, the damping effect of the damper 50 can be applied only in a minute region (Δ ₁ upward and Δ ₂ downward) at the initial position (initial state).

(Vibration presentation operation of the vibration presentation device 10)
FIG. 5 is a block diagram showing a control block of the vibration presenting apparatus according to the present embodiment. 6A shows the signal waveforms of the signals V _S , Vd, and Vc shown in FIG. 5, FIG. 6B shows the vibration waveforms, and S ₁ shows the amplitude when the braking action is performed by the damper. waveform, S ₂ represents the amplitude waveform of when there is no braking action by the damper.

As illustrated in FIG. 5, the vibration on signal V _S is input to the control unit 200, and the drive signal Vd (for example, an AC signal such as a pulse signal) is output to the drive circuit 210. The coil 110 is energized by the coil drive signal Vc that has been amplified by the drive circuit 210. A Lorentz force is generated in the coil 110 by the magnetic field H generated between the magnet 130 and the center yoke 122 and the coil current.

  As shown in FIG. 6A, when the coil 110 is pulse-driven, it vibrates in the direction B shown in FIG. 1A, and the vibration panel 20 as the vibration panel vibrates. The vibration panel 20 vibrates by pulse driving up to times t1, t2, t3, and t4, resulting in a vibration waveform as shown in FIG.

6 (b), the vibration waveform S ₂ is the amplitude waveform of when there is no braking action by the damper. Since the present embodiment includes the damper 50, the amplitude waveform is a braking action by the damper. That is, after completion of excitation of the time t4, the remaining vibration is quickly attenuated as vibration waveform S _1. When the residual vibration after the vibration presentation is quickly attenuated, the touch of the tactile presentation can be improved.

In FIG. 6B, a region Da of a minute region (upward Δ ₁ and down Δ ₂ ) centering on the initial position (initial state) is a damper effective range.

On the other hand, the braking action of the damper 50 does not work in a range exceeding the above-mentioned minute region (Δ ₁ upward, Δ ₂ downward).

(Second embodiment of the present invention)
FIG. 7 is a front view of the vibration presenting apparatus according to the second embodiment of the present invention. In the second embodiment, the tension coil spring used in the first embodiment is a compression coil spring. Since the other configuration is the same as that of the first embodiment, the different configuration will be described below.

(Spring 65)
The spring 65 functions as a pressure unit that applies a compressive force to the support unit 40. In the present embodiment, as shown in FIG. 7, the spring 65 uses a compression coil spring. As shown in FIG. 7, the spring 65 is composed of a compression coil portion. In this compression coil portion, the upper end portion 65 a abuts on the corner portion 36 of the housing 30, and the lower end portion 65 b abuts on the corner portion 26 of the vibration panel 20 in a compressed state. Thereby, a compressive force is applied to the support portion 40 interposed between the vibration panel 20 and the housing 30.

(Third embodiment of the present invention)
FIG. 8 is a front view of a vibration presenting apparatus according to the third embodiment of the present invention. In the third embodiment, a piezoelectric actuator 150 is used instead of the voice coil motor 100 as the vibration generating unit used in the first embodiment. Since the other configuration is the same as that of the first embodiment, the different configuration will be described below.

  The piezoelectric actuator 150 is, for example, a morph-type piezoelectric element that includes a plate and a piezoelectric element, and is fixed to the lower surface 20 b of the vibration panel 20. This morph-type piezoelectric element is a piezoelectric element having a structure in which a layered or plate-shaped piezoelectric element is bent. The plate is formed using, for example, a conductive metal material such as aluminum, nickel, copper, and iron, an alloy material containing them, or an alloy material such as stainless steel.

  Examples of the material of the piezoelectric element include lithium niobate, barium titanate, lead titanate, lead zirconate titanate (PZT), lead metaniobate, polyvinylidene fluoride (PVDF), polylactic acid, and the like. This piezoelectric element is, for example, a single-layer unimorph type in which a film formed using the above material is formed on one surface of a metal plate, and a stacked film formed by stacking a film formed using the above material. This is a unimorph type piezoelectric element.

  Since the piezoelectric actuator 150 is deformed by tension or compression when a voltage is applied, the piezoelectric actuator 150 can be vibrated by performing pulse driving as shown in FIG. 4, and the vibration panel 20 can be presented with vibration.

With respect to the damping characteristic (braking characteristic) of this damper, a region Da of a minute region (upward Δ ₁ and down Δ ₂ ) centering on the initial position (initial state) is the damper effective range. Therefore, in the large vibration region (region A ₂ ) as shown in FIG. 6B, the excitation action is not easily inhibited in the excitation operation. On the other hand, in the small vibration region (region A ₁ ) as shown in FIG. 6B, the braking action by the damper works in the entire region, so that the residual vibration is quickly attenuated after the excitation is finished. That is, the residual vibration after the vibration presentation is quickly attenuated, so that the touch of the tactile presentation can be improved.
(2) In the second embodiment, since the compression coil spring is used in addition to the effect of the first embodiment, the hooking process does not occur in the assembling process, and the assembling efficiency is improved. There is.
(3) In the third embodiment, in addition to the effects of the first embodiment, the piezoelectric actuator 150 can be used as a vibration generation source by pasting and fixing it to the lower surface 20b of the vibration panel 20. As a result, the structure can be simplified and the apparatus can be thinned.
