Abstract

A touch sensing device including a vibratable plate, a touch sensor, a vibration generator including a plunger, an operation face, an opposed part opposed to the vibratable plate in a first direction, and a cushioning member. The plunger is configured to reciprocate in the first direction so as to vibrate the vibratable plate in the first direction. The operation face is to be touched by a detection object for inputting to operate the touch sensing device, and is vibratable as a result of vibration of the vibratable plate. The cushioning member is interposed between the opposed part and the vibratable plate in the first direction. The cushioning member is configured to reduce an amount of displacement in the first direction of the vibratable plate arising from the vibration in the first direction such that the amount is smaller than an amount of movement in the first direction of the plunger.

Dependent claims

A touch sensing device comprising:

a vibratable plate;
a touch sensor;
a vibration generator including a plunger, the plunger being configured to reciprocate in a first direction so as to vibrate the vibratable plate in the first direction;
an operation face to be touched by a detection object for inputting to operate the touch sensing device, the operation face being vibratable in the first direction as a result of vibration of the vibratable plate;
an opposed part in opposing relation to the vibratable plate in the first direction;
a cushioning member interposed between the opposed part and the vibratable plate in the first direction, the cushioning member being configured to reduce an amount of displacement in the first direction of the vibratable plate arising from the vibration in the first direction such that the amount is smaller than an amount of movement in the first direction of the plunger;
a load detector to detect a load applied to the operation face when the operation face is touched by a detection object for inputting, and to output or change an output signal;
and
a control part to drive the vibration generator in response to an input of the output signal form the load detector, or in response to a change in the output signal from the load detector, wherein
the control part is configured:
(1) to determine whether the load applied to the operation face is equal to or larger than a first load on the basis of the input of the output signal from the load detector, or on the basis of the change in the output signal form the load detector;
(2) when determining that the load is equal to or larger than the first load, to drive the vibration generator and determine whether the load applied to the operation face is equal to or less than a second load on the basis of the input of the output signal from the load detector, or the change in the output signal from the load detector, within a predetermined period, wherein the second load is smaller than the first load;
and
(3) when determining that the load is equal to or less than the second load, to drive the vibration generator.
