Abstract

The invention discloses an input device and electronic equipment, belonging to the field of intelligent equipment. The input device includes a processing unit and a plurality of transceiver units arranged in an array; the transceiver unit is used to transmit ultrasonic waves and receive the reflected ultrasonic waves, and the directions in which the multiple transceiver units emit ultrasonic waves are parallel to each other; the processing A unit configured to generate an input signal according to at least one of the time difference between the time when each of the transceiver units transmits the ultrasonic wave and the time when the ultrasonic wave is received, and the intensity difference between the transmitted ultrasonic wave and the received ultrasonic wave. This process does not require the user to perform a touch operation, but only requires the user's finger to be on the path of ultrasonic emission, which solves the problem that the touch function cannot be realized without the touch operation.

Description

technical field [0001] The invention relates to the field of intelligent equipment, in particular to an input device and electronic equipment. Background technique [0002] With the development of smart phones, the touch function has become one of the indispensable functions of smart phones. At present, the touch function mainly includes two parts: touch button instruction and fingerprint recognition. The touch function is usually designed as a touch button or integrated on the touch screen. When the user touches the touch button or the touch screen with a finger, an electrical signal is generated. The corresponding touch button instruction or user fingerprint image can be determined. [0003] However, such a touch function requires a user to perform a touch operation, and if the user does not perform a touch operation, an electrical signal cannot be generated, and thus the touch function cannot be realized. Contents of the invention [0004] In order to solve the proble...
