Circuit and electronic device

Abstract

The embodiment of the present application relates to the field of touch, and discloses a circuit and an electronic device. The circuit includes: an antenna, a touch chip, and a communication chip, wherein the antenna forms a detecting electrode, and the detecting electrode is electrically connected to the touch chip and the communication chip respectively; and when a finger touches the antenna, the capacitance of the antenna changes, and the touch chip detects that the transmission data of the detecting electrode changes, and the touch chip triggers the electronic device to execute an instruction corresponding to the touch operation. Compared with the prior art, the circuit and the electronic device can realize two functions of the antenna and the touch through the antenna, effectively combine the functions of the touch and the antenna, and the circuit designed by the present application occupies a small volume, and the touch operation is more sensitive.

Description

technical field [0001] The embodiments of the present application relate to the field of touch control, and in particular to a circuit and an electronic device. Background technique [0002] In recent years, with the continuous development of communication technology and the continuous advancement of science and technology, electronic devices such as earphones, watches, and bracelets have become indispensable tools in people's daily life. Especially electronic devices such as bluetooth headsets, bluetooth watches, and bluetooth bracelets with bluetooth antennas have brought great convenience to people's lives. At present, electronic devices such as Bluetooth headsets, Bluetooth watches, and Bluetooth bracelets are small in size and use convenient wireless connections to communicate with other devices, making them more and more widely used. [0003] But there are at least the following problems in the prior art: there is a contradiction between miniaturization and functional...

Problems solved by technology

[0003] But there are at least the following problems in the prior art: there is a contradiction between miniaturization and functional diversification, such as the needs of functions such as controlling the volume and switching songs in the Bluetooth earphone, which cannot be solved by a single button, but a plurality of buttons need more space, resulting in The size of electronic equipment becomes larger

The diversification of functions also requires a larger battery to support, which will also take up more space, and will also cause the volume of electronic equipment to become larger

And in the case of limited space, if the space occupied by the antenna is large, the touch area will be reduced, resulting in insensitive detection
