Problems solved by technology

[0006] However, in the conventional tactile display device, the frequency of the ultrasonic wave is higher than the audible range (about 20 kHz or higher), and the frequency of the ultrasonic wave itself is not particularly optimized, so it may not be able to provide a good tactile sensation.

Embodiment approach

[0026] figure 1 It is a perspective view showing the electronic device 100 of the embodiment.

[0027] As an example, the electronic device 100 is a smartphone terminal or a tablet computer using a touch panel as an input operation unit. The electronic device 100 may be a device that uses a touch panel as an input operation unit, and therefore may be, for example, a portable information terminal or a device that is installed at a specific place such as an ATM (Automatic Teller Machine: automatic teller machine) and used.

[0028] The input operation part 101 of the electronic device 100 is equipped with a display panel under the touch panel, and the display panel displays various buttons 102A of a GUI (Graphic User Interface) or a slider 102B (hereinafter referred to as the GUI operation part). 102).

[0029] The user of the electronic device 100 usually touches the input operation unit 101 with a fingertip to operate the GUI operation unit 102 .

[0030] Next, use figure...

Abstract

The present invention aims to provide a drive control device, an electronic device, and a drive control method that can provide a good sense of touch. The drive control device is the first device for driving an electronic device including a display panel, a touch panel disposed on a display surface side of the display panel, and a first vibration element that vibrates an operation surface for performing operation input on the touch panel. A drive control device for a vibrating element includes a drive control unit that drives the vibrating element using a drive signal that generates a natural vibration in an ultrasonic frequency band on the operating surface, and uses the intensity of the natural vibration to adjust the intensity of the natural vibration to the operating surface. The above-mentioned vibrating element is driven in a manner that changes the position of the operation input and the degree of change of the position over time.

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 are: a display unit; a contact detection unit that detects the contact state of the user's operation part with the above-mentioned display unit; A vibrating tactile display device (for example, refer to Patent Document 1). [0003] The haptic presentation device further includes a vibration waveform data generation unit configured to generate waveform data for generating the tactile vibration based on the detection result of the contact detection unit. In addition, the haptic presentation device further includes an ultrasonic modulation unit for modulating the waveform data generated by the vibration waveform data generation unit using ultrasonic waves as a carrier wave, and using the ultrasonic modulation signal generated by the modulation processing as a The signal for generating the tactile v...
