Abstract: 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.

Abstract: A test box, comprising: a test box body in which chamber used for placing a machine is formed; a microphone provided on the test box body; and a rotating component rotatably connected to the test box by means of a connecting assembly. The rotating component is provided with a through hole, and one end of the microphone passes through the through hole and extends into the chamber of the test box body. In the test box, the microphone is rotatably provided on the test box body, and one end of the microphone extends into the inner chamber of the test box body. By adjusting the position of the microphone, the position of the component in the tested machine that produces noise is determined, so that the component in the machine that produces noise is determined, thereby implementing the detection of a machine in which a small component produces noise. Moreover, the test box features a simple structure and low costs, and reduces costs while improving the detection efficiency.

Abstract: 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.
