Abstract

The present application provides a terminal device with a noise suppression structure, which includes an antenna, a middle frame and a first component, the middle frame includes a metal middle plate and a metal frame, the antenna is arranged on the metal frame, and the metal The middle plate includes 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 , the terminal includes a noise suppression structure, the noise suppression structure is arranged on the metal middle plate, the noise suppression structure includes a hollow area penetrating through the first surface and the second surface, the hollow area and the The first cavity is connected, and the digital signal noise using the first cavity as the transmission medium has a propagation path in the direction of the antenna, and the propagation path passes through the hollow area, and the hollow area is used to suppress the noise passing through the antenna. The digital signal noise transmitted by the propagation path, so as to prevent the digital signal noise from affecting the working performance of the antenna.

Description

technical field [0001] The present application relates to the technical field of mobile terminals, and in particular, to a terminal device with a noise suppression structure. Background technique [0002] When the mobile terminal equipment is working, the internal circuit boards, multimedia devices and connectors and other electronic components will generate related digital signal noise; and usually the circuit board of the mobile phone, the battery and the metal back frame of the display screen and other components and the middle frame of the mobile phone will exist. In the slot space, the harmonics of the digital signal noise may be transmitted to the antenna located at the edge of the middle frame through the slot space as a transmission path, resulting in poor working performance of the antenna. The harmonics of digital signal noise of any frequency can be transmitted without loss in the gap after the harmonic is greater than the cut-off frequency. [0003] How to desig...
