Embodiment approach 1

[0029] figure 1 It is a perspective view showing the electronic device 100 according to the first embodiment.

[0030] As an example, the electronic device 100 is a smartphone terminal or a tablet computer with a touch panel as an input operation unit. Electronic device 100 may be a device that uses a touch panel as an input operation unit, and therefore may be a device that is installed in a specific place and used such as a portable information terminal or an ATM (Automatic Teller Machine).

[0031] The input operation unit 101 of the electronic device 100 is provided with a display panel under the touch panel, and various buttons 102A or slide bars 102B (hereinafter referred to as GUI) of a GUI (Graphic User Interface: Graphic User Interface) are displayed on the display panel. operation part 102).

[0032] A user of the electronic device 100 usually touches the input operation unit 101 with a fingertip in order to operate the GUI operation unit 102 .

[0033] Next, use ...

Embodiment approach 2

[0263] Figure 17 It is a sectional view showing the structure of the support body 530 according to the second embodiment. Figure 17 The cross-sectional structure shown with the Figure 6 correspond. The electronic device of Embodiment 2 includes a support body 530 instead of the support body 130 of Embodiment 1. FIG. It should be noted that, since other components are the same, only the support body 530 will be described here.

[0264] The supporting body 530 includes: a base 531 , a base 532 , a housing 533 and an MR (Magneto-Rheological) fluid 534 . It should be stated that in Figure 17 shown in the Figure 6 Same XYZ coordinate system. The support body 530 uses a magnetic field to control the support stiffness.

[0265] The base 531 and the base 532 respectively seal the cylindrical housing 533 up and down. An MR fluid 534 is enclosed in an internal space formed by the base 531 , the base 532 , and the housing 533 .

[0266] The MR fluid 534 is a fluid whose vis...

Abstract

An object of the present invention is to provide an electronic device capable of providing various good tactile sensations. The electronic device includes: a top panel having an operation surface on an upper surface side; a coordinate detection unit for detecting coordinates of an operation input performed on the operation surface; a case disposed on the back side of the top panel; The first vibrating element; the supporting body, which supports the top panel to the casing, and can switch the support stiffness of the top panel relative to the casing between a first level and a second level lower than the first level; and A control unit that sets the support rigidity of the support body to a first level when driving the first vibrating element with a first drive signal that generates natural vibrations in the ultrasonic frequency band on the operation surface, and then generates vibrations in the hearing range on the operation surface. When the first vibrating element is driven by the second driving signal, the supporting rigidity of the supporting body is set to the second level.

Description

technical field [0001] The present invention relates to electronic equipment. Background technique [0002] Conventionally, there is a data input device including a touch input interface having a touch detection mechanism, and a plurality of regions made of a material whose shape, size, or viscosity is changed by voltage. The above-mentioned data input device is characterized in that the material in the specific area touched by the user is at least temporarily activated by applying a voltage to the area where the shape, size, and viscosity of the material in the area where the user's touch is detected by the above-mentioned touch detection mechanism. , thereby prompting the above-mentioned specific area touched by the above-mentioned user through the sense of touch. These materials are smart fluids such as electroactive polymers (EAP), electroviscous fluids, or piezoelectric materials (for example, refer to Patent Document 1). [0003] Patent Document 1: Japanese Unexamine...
