Printed circuit board provided with touch key

Abstract

The invention discloses a printed circuit board provided with touch keys. The printed circuit board comprises at least two touch keys, a metal ring and a first antenna, wherein the touch keys are suitable for press or touch operation; the metal ring is suspended above the printed circuit board, sleeves at least one touch key with a distance from the touch key to the other one is less than a predetermined threshold value, and serves as an induction antenna of the sleeved touch key with the distance from the touch key to the other one is less than the predetermined threshold value; and the first antenna is distributed on the periphery of the other touch key which is not sleeved by the metal ring, and serves as an induction antenna of the touch key which is not sleeved by the metal ring. By adopting the scheme, the reliability of an intelligent remote controller can be improved, and the PCB wiring difficulty of the intelligent remote controller can be reduced.

Description

technical field [0001] The invention relates to the field of printed circuit boards, in particular to a printed circuit board provided with touch keys. Background technique [0002] With the development of electronic technology, the functions of the smart remote control continue to increase, and more and more buttons require complex setting functions. For example, the voice key needs to be set in three receiving states to meet the user's needs. One of the receiving states is used to meet the user's purpose of enabling voice recognition, the other receiving state is used to meet the user's purpose of enabling chat, and another The receiving state is used to satisfy the user's purpose of initiating voice recording. Another example is the OK key, which needs to be set to different receiving states to realize functions such as opening the space mouse and pressing Enter. [0003] In order to realize the stable function of the function keys on the smart remote control, it can be...

AI Technical Summary

Problems solved by technology

[0003] In order to realize the stable function of the function keys on the smart remote control, it can be realized by increasing the antenna area and the distance between different antennas. However, due to the small space and complicated wiring, the printed circuit board (Printed Circuit Board, PCB) The difficulty of wiring is more complicated, and the reliability of the smart remote control is reduced
