Abstract: A laser source and a laser projection apparatus are provided. The laser source includes a laser assembly. The laser assembly includes a mounting substrate, a light-emitting group, and a conductive connecting portion. The mounting substrate is a first printed circuit board and includes a first surface, a first region, and a second region. The first region and the second region are discontinuously distributed, and the first region is connected with the second region through an internal wiring of the mounting substrate. The light-emitting group is electrically connected with the first region. A first end of the conductive connecting portion is connected with the second region, and a second end of the conductive connecting portion is configured to be electrically connected with a second printed circuit board, so as to electrically connect the light-emitting group with the second printed circuit board.

Abstract: Disclosed is a signal processing method for regulating interference and interference immunity in a terminal device and a related apparatus. A terminal device obtains a state factor used for reflecting a communication state of a communication module and a usage state of a functional module. The terminal device down-regulates the source drive voltage or the source drive current when a frequency division frequency or frequency multiplication frequency of a signal transmitted on the signal line falls within a working frequency range. The terminal device up-regulates the source drive voltage or source drive current when a voltage amplitude of an electromagnetic wave component that is of an electromagnetic wave radiated by the communication module and that is coupled to the signal line is greater than a threshold. In this way, phenomena such as dropped calls and blurry screens can be mitigated, optimizing the user experience.

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.
