A device for detecting a missing element on a circuit board comprising a positioning tray, a data processing assembly, a lifting control assembly, and a detecting assembly. The positioning tray supports and positions a circuit board to be tested. The data processing assembly is connected with the lifting control assembly and the detecting assembly, and sends a control signal to the lifting control assembly, receives detection data sent by the detecting assembly, and compares the detection data with preset reference data to obtain a detection result of a missing element. The detecting assembly moves up and down between an initial position and a preset position under the control of the lifting control assembly, and sends the detection data to the data processing assembly according to a contact state with elements on the circuit board to be tested at the preset position.

Device and method for detecting missing element on circuit board

A method of locating a microphone, a device of locating a microphone and a system of locating a microphone. The method includes: determining an initial position of the microphone located in front of a light outgoing surface of a display screen; determining a target position of the microphone; determining a first displacement of the microphone in a direction perpendicular to the light outgoing surface of the display screen based on the target position and the initial position; determining a second displacement of the microphone in a direction parallel with the light outgoing surface of the display screen based on the target position and the initial position; and controlling the microphone to move to the target position based on the first displacement and the second displacement.
