Therefore, only the vibration damping member 420 is sandwiched between the first case portion 200 of the structure body SA and the support body 400 of the structure body SB, and they are directly connected.

<Action/Effect>
When the touch panel display 10 configured as described above recognizes the user's operation by touching the touch panel of the touch panel module 100 with the user's finger, the touch panel display 10 activates the vibration actuator in accordance with the user's operation. By driving the touch panel module 100, the touch panel module 100 is vibrated and a tactile sensation is fed back to the user's finger.

The user performs a touch operation on the touch panel of the touch panel module 100 on which icons and the like are displayed. When a pressing force due to a touch operation is applied to the touch panel module 100, distortion occurs in the strain-generating member 310 fixed to the rear of the first case part 200 via the first case part 200. The generated strain is detected by the strain gauge 320 held between the first case section 200 and the strain generating member 310, and the strain gauge 320 transmits a detection signal to the control section of the circuit board 510.

The control unit supplies a drive current to the actuator unit 350 in order to feed back a tactile sensation to the user's finger in response to a touch operation on the touch panel. At this time, in the actuator section 350, a magnetic field is generated in the coil by the drive current supplied from the control section, and a magnetic force is generated in the core of the actuator section 350. Then, the actuator section 350 causes the movable member 340, which is disposed close to the core, to be attracted to the core by magnetic force. Then, the movable member 340 deforms in the direction perpendicular to the plane inside the stepped portion formed by bending the base portion 360 into an L-shape, and moves in one direction (backward). On the other hand, the control unit stops supplying the drive current after moving the movable member 340 in one direction (backwards). At this time, the magnetic force generated in the core of the actuator section 350 disappears. Then, the movable member 340 that has been adsorbed to the core moves in the opposite direction (forward) from one direction (backward) due to the biasing force possessed by the elastic supports 330a and 330b joined to the movable member 340. The control unit repeats the supply and stop of the drive current in a pulse waveform as described above, thereby moving the movable member 340 back and forth in a straight line, and generating vibrations with the vibration axis AL in the front-rear direction.

The vibration generated in the movable member 340 is conducted to the strain member 310 joined to the movable member 340. The vibration is then transmitted to the touch panel module 100 via the first case part 200 fixed to the strain-generating member 310, and the touch panel module 100 feeds back the vibration as a tactile sensation to the user's finger.

On the other hand, the tactile sensation that is fed back is directly connected to the user's operability, so it needs to be a comfortable tactile sensation. Therefore, it is necessary to set the tactile sensation to be fed back by acquiring vibration characteristics that correlate with the tactile sensation.

The vibration characteristics here are obtained using a measurement device such as an acceleration sensor, for example, with the central part of the surface of the touch panel of the touch panel module 100 as the measurement point. Specifically, a measuring device is fixed at a measurement location, vibration is generated by driving the actuator section 350, and, for example, a temporal change in acceleration as a vibration characteristic is obtained. The vibration characteristics are evaluated, for example, in the form of a graph in which acceleration is displayed on the vertical axis and elapsed time is displayed on the horizontal axis.

For example, as shown in FIG. 9, a difference in vibration characteristics results in a difference in the tactile sensation that is fed back. In the vibration characteristic example of setting A in FIG. 9A, the tactile sensation fed back can be felt as the tactile sensation of pressing a switch with a sharp and crisp feel. Further, in the vibration characteristic example of setting B in FIG. 9(b), the tactile sensation fed back can be felt as a tactile sensation that has a long aftertaste after pressing the switch.

To change the vibration characteristics in order to set the tactile sensation to be fed back, there is a method of changing the vibration characteristics by changing the drive control of the actuator section 350 that generates vibration, and a method of changing the vibration characteristics by changing the configuration. We will respond by using a method to change the vibration characteristics.

When changing the vibration characteristics by changing the drive control of the actuator section 350, the vibration characteristics can be changed by changing the settings of the control section of the circuit board 510 and changing the frequency or amount of the drive current. It will be done. In this case, the vibration characteristics can be easily changed by, for example, changing the constants of the drive circuit that drives the actuator section 350 or changing the program of the control IC of the control section.

Furthermore, when changing the vibration characteristics by changing the configuration, it is necessary to reduce the number of components that affect the vibration characteristics in advance. In the present embodiment, the structure SA and the structure SB are connected to each other at a joint CP of the elastic support parts 330a and 330b, which is surrounded by a two-dot chain line shown in FIG. Only a damping member 420 is sandwiched between the first case portion 200 of the body SA and the support body 400 of the structure body SB. Therefore, in the first case part 200, the elastic support parts 330a and 330b that elastically support the movable member 340 so as to be movable in the vibration direction, and the vibration damping member 420 having a damper function affect the vibration characteristics. . At this time, since the elastic support parts 330a and 330b are coupled to the movable member 340, the vibration characteristics can be changed by changing the frequency or the amount of current of the drive current to the actuator part 350. On the other hand, as shown in FIG. 7, the leg portion 220 is in close contact with the damping member 420 from the direction indicated by the thick arrow CC1, and the damping member 420 is connected to the leg portion 220 of the first case portion 200 and the support body. 400 and a support frame 410. Moreover, with respect to the second case part 500 disposed rearwardly than the support frame 410, the vibration damping member 420 is connected to the first case part 200 and the second case part 500 at positions shifted in the RH direction and the anti-RH (LH) direction. It is located between the support frame 410 and the case part 500, and is provided at a position spaced apart from the fixing locations of the support frame 410 and the first case part 200 and the second case part 500. Therefore, the vibration damping member 420 naturally becomes a component that influences the vibration characteristics, and in order to change the vibration characteristics, the vibration damping member 420 may be changed. For example, the thickness, size, material, etc. of the vibration damping member 420 may be changed.

Further, the base portion 360 is fixed to the support frame 410 by being screwed to the boss 361 from behind through the support frame 410.
