Problems solved by technology

[0002] The traditional rocker device adopts a variable resistance design, and its disadvantage is that the characteristics of the variable resistance will change with time, so it needs to be recalibrated
In addition, the stick body of the traditional mechanical rocker device has a considerable height (significantheight), so it is not suitable for portable devices or wearable devices.

other Embodiment approach

[0049] In other embodiments, the bottom surface 1911 and the outer surface 1915 of the cone 191 may be discontinuous surfaces, for example, a plurality of extension structures extend outward from the center of the cone 191, and the plurality of extension structures correspond to The electrodes of the capacitive sensing region 113 are provided.

[0050] The operating rod 192 extends from the bottom surface 1911 of the cone 191, for example, extends vertically, and passes through the second through hole 151 and the first through hole 131 in sequence, protruding The portion on the fixing plate 13 is used as an operating end for the user to push. In one embodiment, the operating rod 192 is integrally formed with the cone 191 , so the operating rod 192 can also be made of conductive material. In another embodiment, the operating rod 192 and the cone 191 are made separately and combined with each other, for example, by securing or embedding. There is no specific limitation, as long...

Abstract

The invention provides a capacitive joystick device including a substrate, a fixed plate, a movable member, a plurality of elastic elements, a cone and an operation stick. The substrate includes a ground region and a capacitance sensing region. The fixed plate includes a first opening. The movable member includes a second opening. The elastic elements are symmetrically disposed between the fixed plate and the movable member. The cone is disposed between the movable member and the substrate, and includes a base, a vertex and a lateral surface. The base presses against the movable member. The vertex is disposed on the ground region of the substrate. The lateral surface is aligned with the capacitance sensing region of the substrate. The operation stick extends from the base of the cone and passes through the first opening and the second opening.

Description

technical field [0001] The present invention relates to a rocker device, more particularly, to a capacitive rocker device. Background technique [0002] The traditional rocker device adopts a variable resistance design, and its disadvantage is that the characteristics of the variable resistance will change with time, so it needs to be recalibrated. In addition, the rod body of the traditional mechanical rocker device has a considerable height (significant height), so it is not suitable for portable devices or wearable devices. Contents of the invention [0003] In view of this, the present invention further proposes a capacitive rocker device, which has the characteristics of small size and no correction, and is suitable for various portable devices or wearable devices. [0004] The invention provides a capacitive rocker device, which includes a base plate, a fixed plate, a movable part, a plurality of elastic elements, a cone and an operating rod. The substrate includes...
