1. A terminal device, comprising:
a noise suppression structure that includes an antenna, a middle frame, and a first component,
wherein the middle frame comprises a metal middle plate and a metal bezel, the antenna is disposed on the metal bezel, the metal middle plate comprises a first surface and a second surface opposite to the first surface, the first component is mounted on the middle frame, and a first cavity is formed between the first component and the first surface;
wherein the noise suppression structure is disposed on the metal middle plate, the noise suppression structure comprises a hollow region running through the first surface and the second surface, and the hollow region communicates with the first cavity;
wherein digital signal noise is generated based on the first component working, wherein the digital signal noise uses the first cavity as a transmission medium and 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 in the propagation path; and
wherein the first component is a display screen, the display screen comprises a metal backplane opposite to the first surface, and the metal backplane is provided with a backplane noise suppression structure, wherein the backplane noise suppression structure comprises a second hollow region running through the metal backplane.
