Problems solved by technology
[0009] However, the frequency of the ultrasonic wave in the conventional tactile sensation presentation device should be higher than the frequency of the audible frequency band (about 20 kHz or higher), and no special consideration is given to the frequency of the ultrasonic wave itself, so there is a concern that a good tactile feeling cannot be provided.
[0010] In addition, the existing tactile prompting device stimulates the touch panel along the first direction horizontal to the contact surface, so there is a concern that a good tactile sensation cannot be provided.

Embodiment Construction
[0028] Embodiments of the drive control device, electronic equipment, and drive control method to which the present invention is applied will be described below.
[0029]
[0030] figure 1 It is a perspective view showing the electronic device 100 of the embodiment.
[0031] 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 installed at a specific location such as a portable information terminal or an ATM (Automatic Teller Machine: Automatic Teller Machine) for use.
[0032] 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 based on a GUI (Graphic User Interface) are displayed on the display panel (hereinafter , referred to as the GUI operation section 102).

An object of the present invention is to provide a drive control device, an electronic device, and a drive control method that can easily recognize the direction of a position where a user should perform an operation input by providing a good tactile feeling. The drive control device controls the first vibration of an electronic device including a display panel, a touch panel disposed on a display surface side of the display panel, and a first vibrating element that vibrates an operation surface for operating an input to the touch panel. The element is driven, and the drive control device includes a first drive control unit. The first drive control unit drives the first vibrating element with a drive signal that causes the operation surface to generate natural vibrations in the ultrasonic frequency band, and the display panel displays The relationship between the position of the GUI operation unit and the position of the operation input to the operation surface is predetermined, and the first vibrating element is driven so as to switch the strength of the natural vibration.
Description
technical field [0001] The present invention relates to a drive control device, electronic equipment and a drive control method. Background technique [0002] Conventionally, there is a tactile sensation presenting device, which includes: a display mechanism; a contact detection mechanism that detects the contact state of the user's operation part with the above-mentioned display mechanism; A tactile vibration is generated to give a predetermined tactile sensation to the touched operation site (for example, refer to Patent Document 1). [0003] The tactile sensation presenting device further includes a vibration waveform data generation unit for generating waveform data for generating the tactile vibration based on the detection result of the contact detection unit. In addition, the tactile sensation presenting device further includes ultrasonic modulation means for modulating the waveform data generated by the vibration waveform data generation means using ultrasonic waves...
