Abstract

The embodiment of the invention provides a circuit board assembly and an electronic device. The circuit board assembly is composed of a printed circuit board, an antenna and a microphone set. The antenna is arranged at one side of the printed circuit board and has a feed port. The microphone set is arranged at the other side of the printed circuit board and is located at a projection zone of the feed port at the printed circuit board. According to the invention, because the antenna and the microphone set are arranged at the different sides of the printed circuit board, the printed circuit board can weaken or shield an interference signal caused by the antenna to reduce the interference with the signal of the microphone set by the signal of the antenna, so that the signal stability of the microphone set can be improved and stability of the electronic device can be enhanced.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a circuit board assembly and electronic equipment. Background technique [0002] Electronic devices such as smart phones are equipped with antennas to realize radio frequency communication with other electronic devices. On the other hand, the electronic device is also provided with a microphone to realize the sound signal collection function of the electronic device. [0003] Currently, in electronic equipment, antennas and microphones are placed in close proximity. When the antenna transmits radio frequency signals, the radio frequency current in the antenna is relatively large. When the microphone collects external sound signals, the current in the microphone is small. Therefore, the antenna will interfere with the signal of the microphone, affecting the stability of the signal of the microphone, thereby reducing the stability of the electronic device.
