Abstract: This application provides a terminal device, including a noise suppression structure, where the noise suppression structure is disposed on the metal middle plate, the noise suppression structure includes a hollow region running through the first surface and the second surface, and the hollow region communicates with the first cavity, so that digital signal noise that uses the first cavity as a transmission medium has a propagation path in a direction toward the antenna, the propagation path passes through the hollow region, and the hollow region is used to suppress the digital signal noise transmitted through the propagation path, so as to prevent antenna operating performance from being affected by the digital signal noise.

Abstract: The present application provides a light source assembly, an optical engine, and a projector. The light source assembly includes a first housing, a second housing, multiple lasers, multiple beam combination mirror groups, a convex lens, a reflector, a concave lens, an angle adjustment element, and a converging lens. The first housing has multiple light inlets corresponding one-to-one to the multiple lasers, and a light outlet. Each of the lasers is disposed at a corresponding light inlet. The multiple beam combination mirror groups are disposed in the first housing. The second housing has a light inlet and a light outlet, and the light outlet of the first housing is connected with the light inlet of the second housing. The reflector, the concave lens, and the angle adjustment element are disposed in the second housing. The converging lens is disposed at the light outlet of the second housing.

Abstract: A digital light processing projector includes a light machine having a shell. The shell is provided with a first positioning post and a second positioning post. A digital micromirror device is configured with a first positioning hole and a second positioning hole. The first positioning post is located in the first positioning hole. The second positioning post is located in the second positioning hole. The light machine includes a circuit board assembly, a pressing plate, and a first connection assembly for fixed connection with the shell, and fixation of the pressing plate, the circuit board assembly and the digital micromirror device on the shell.

Abstract: A laser module includes an encapsulating support, at least one laser, a sealing gasket, and a pressing plate. Each laser includes a supporting plate and a laser body that is fixed to the supporting plate. The supporting plate is fixed on the encapsulating support, and a surface of an end of the laser body away from the supporting plate is a light exit end face. The sealing gasket is located on a surface of the supporting plate close to the light exit end face, and the sealing gasket has a first opening at a position corresponding to the laser body. A pressing plate is located on a surface of the sealing gasket away from the supporting plate; the pressing plate is fixedly connected to the encapsulating support, and the pressing plate has a second opening at a position corresponding to the first opening.
