Abstract: A vibration application mechanism including a vibratable part, a load sensor to sense a load applied to the vibratable part, a vibration generator to vibrate the vibratable part, and a controller. The controller makes a first determination as to whether a load sensed by the load sensor has equaled or exceeded a first threshold value; if the first determination is such that the sensed load has equaled or exceeded the first threshold value, the controller drives the vibration generator and makes a second determination, during a predetermined period, as to whether a load sensed by the load sensor has fallen below a second threshold value, wherein the period starts when the sensed load has equaled or exceeded the first threshold value; and if the second determination is such that the sensed load has fallen below the second threshold value during the period, the controller does not drive the vibration generator.

Abstract: A vibration generator including a coil, a plunger including a first shaft and a second shaft, and a frame. The first shaft is received in the coil such as to be movable in a first direction. The second shaft extends in a second direction orthogonal to the first direction, is disposed on the other side in the first direction relative to the coil with a gap therebetween. The first and second shafts are partly made of a magnetic material so as to be magnetically attractable to the coil and thereby movable to one side in the first direction. The frame is fixed to the first and second shafts at positions on the one and other sides, respectively, in the first direction relative to the coil, and elastically deformable at least partly as a result of movement of the first and second shafts.

Abstract: The invention aims at reducing power consumption without sacrificing advantages of an alternately driving method in the prior art. A matrix addressing circuit for alternately driving pixels arranged in matrix, wherein: a plurality of row electrodes extending in a horizontal direction of a display screen are made to be selectively active for each horizontal scanning period of images to be displayed; a plurality of column electrodes extending in a vertical direction of the display screen are applied with respective pixel voltages that are responsive to the image and correspond to the horizontal scanning period while the pixel voltages have polarities alternating for each frame period of the images; and the pixel voltages have polarities alternating in the vertical direction spatially in a display area within the frame period.
