Abstract: An electronic device 100 according to one embodiment includes: a panel 101; vibrators 102 that vibrates the panel 101; and a vibration controller 109 that controls the vibrators 102 so that when positions of the panel 101 are simultaneously touched by the user, a vibration at a first touch position of the touch positions is greater than a vibration of a second touch position of the touch positions. The vibrators 102 include a first and a second vibrator 102. Where a distance between first touch position and the first vibrator 102 is equal to a distance between second touch position and the first vibrator 102, a transfer characteristic of vibration of the panel 101 between the first vibrator 102 and the first touch position is different from a transfer characteristic of vibration of the panel 101 between the first vibrator 102 and the second touch position.

Abstract: The present disclosure provides a sound collection device that collects a sound while suppressing noise. The sound collection device includes: a storage that stores first data indicating a feature amount of an image of an object indicating a noise source or a target sound source; and a control circuit that specifies a direction of the noise source by performing a first collation of collating image data generated by a camera with the first data, and performs signal processing on an acoustic signal outputted from a microphone array so as to suppress a sound arriving from the specified direction of the noise source.

Abstract: A sound pickup device for picking up a target sound includes: a first input interface that inputs image data generated by a camera; a second input interface that inputs an audio signal output from a microphone array; a controller that determines a sound pickup direction in which the target sound is picked up, based on the image data and the audio signal; and an output interface that outputs information to be presented to the user. The controller determines whether an image indicated by the input image data and an audio sound indicated by the input audio signal are in a predetermined state. When determining that the image and the audio sound are in the predetermined state, the controller causes the output interface to output an instruction to the user, and inputs additional image data and an additional audio signal after the instruction is output, to determine the sound pickup direction.

Abstract: A signal detection device includes a measurer, an arithmetic operation unit, and signal period detector, and detects information such as a cardiac cycle with high accuracy by causing resonance of only a signal such as a heartbeat, the signal having strong pulse characteristics. The measurer measures a signal. The arithmetic operation unit performs nonlinear arithmetic operation processing for amplifying a pulse-like component of the signal measured by the measurer and suppressing a component other than the pulse-like component of the signal measured by the measurer. The signal period detector detects a periodic signal from an output of the arithmetic operation unit.

Abstract: A cardiac potential detection device for detecting R-waves from an electrocardiographic waveform includes a plurality of electrodes, a detector, and a control unit. The detector detects an input voltage applied from the electrodes. The control unit identifies an R-wave based on the input voltage detected by the detector, but suspends identifying R-waves in a detection-suspension period including a period in which the input voltage exceeds a predetermined threshold.

Abstract: An electronic device includes a panel which a user touches, a detector that detects the touch of the user on the panel, a vibrator that vibrates the panel, and a signal generator. The signal generator generates a signal for driving the vibrator, the signal including a drive signal that generates vibration of the panel and a suppression signal that suppresses inertial vibration of the panel. The suppression signal has a degree of suppression the inertial vibration that changes depending on a touch position detected by the detector.
