Abstract
A movement amount calculation unit for integrating, over a movement amount collection time period, a movement amount of a coil unit when the coil unit moves, the movement amount being calculated on the basis of an electromotive force occurring in the coil unit as the coil unit moves, to thereby calculate a movement amount for determination of the coil unit, and a pushing determination unit for determining the existence or nonexistence of a pushing operation by using the movement amount for determination calculated by the movement amount calculation unit are included.
Claims7
A pushing detection device for touch panel, for detecting a pushing operation on a touch panel in an electronic device which includes the touch panel, a body chassis, and at least one voice coil actuator for vibrating the touch panel, the voice coil actuator having a coil unit fixed to the touch panel and a magnetic circuit unit fixed to the body chassis, and in which the touch panel and the coil unit move relatively to the body chassis through the pushing operation on the touch panel, the pushing detection device comprising:
- processing circuitry
- to integrate, over a movement amount collection time period, a movement amount of the coil unit when the coil unit moves, the movement amount being calculated on a basis of an electromotive force occurring in the coil unit as the coil unit moves, to thereby calculate a movement amount for determination of the coil unit;
- and
- to determine existence or nonexistence of the pushing operation by using the calculated movement amount for determination.
An electronic device comprising:
- a touch panel;
- a body chassis;
- and
- a voice coil actuator for vibrating the touch panel, the voice coil actuator having a coil unit fixed to the touch panel and a magnetic circuit unit fixed to the body chassis,
- wherein the touch panel and the coil unit move relatively to the body chassis through a pushing operation on the touch panel.
