Abstract
The present disclosure relates to a press sensing assembly and a terminal device. The press sensing assembly includes: an emitting element including a first side and a second side thereopposite and emitting an ultrasonic wave; a receiving element disposed adjacent to the emitting element, receiving a reflected wave of the reflected ultrasonic wave; and a reflecting pad disposed the first side and the receiving element, and a first surface of the reflecting pad abutting the emitting element and the receiving element, wherein when the second side and/or the receiving element are/is pressed, a region of the reflecting pad corresponding to the pressed region deforms, and a medium density in a deforming region increases.
Claims20
A press sensing assembly, comprising:
- an emitting element including a first side and a second side thereopposite and emitting an ultrasonic wave;
- a receiving element disposed adjacent to the emitting element, receiving a reflected wave of the reflected ultrasonic wave;
- and
- a reflecting pad disposed the first side and the receiving element and having a first surface and a second surface facing away from the first surface, and the first surface of the reflecting pad abutting the emitting element and the receiving element,
- wherein when the second side is pressed, a region of the reflecting pad corresponding to a pressed region deforms, and a medium density in a deforming region increases;
- or
- wherein when the receiving element is pressed, a region of the reflecting pad corresponding to a pressed region deforms, and a medium density in a deforming region increases;
- or
- wherein when the second side and the receiving element are pressed, a region of the reflecting pad corresponding to a pressed region deforms, and a medium density in a deforming region increases;
- wherein the press sensing assembly further comprises a fixing clamp disposed on the second surface of the reflecting pad, the fixing clamp has elasticity for clamping the reflecting pad.
A terminal device, comprising:
- a display screen;
- and
- a press sensing assembly comprising:
- an emitting element emitting including a first side and a second side thereopposite and an ultrasonic wave;
- a receiving element disposed adjacent to the emitting element, receiving a reflected wave of the reflected ultrasonic wave;
- and
- a reflecting pad disposed the first side and the receiving element and having a first surface and a second surface facing away from the first surface, and the first surface of the reflecting pad abutting the emitting element and the receiving element,
- wherein when the second side is pressed, a region of the reflecting pad corresponding to a pressed region deforms, and a medium density in a deforming region increases;
- or
- wherein when the receiving element is pressed, a region of the reflecting pad corresponding to a pressed region deforms, and the medium density in a deforming region increases;
- or
- wherein when the second side and the receiving element are pressed, a region of the reflecting pad corresponding to a pressed region deforms, and a medium density in a deforming region increases;
- wherein the press sensing assembly further comprises a fixing clamp disposed on the second surface of the reflecting pad, the fixing clamp has elasticity for clamping the reflecting pad.
