Document Type and Number:

WIPO Patent Application WO/2020/155064

Kind Code:

A1

Abstract:

Provided are an information transmission method, a communication apparatus, a portable device and a communication system. The method is applied to a portable device, and the method comprises: receiving and/or sending information in an electric field coupling manner by means of a first coupling electrode arranged on the portable device and a second coupling electrode at an opposite terminal. In the embodiments of the present application, information is received and/or sent in an electric field coupling manner, not only improving the communication quality and connection reliability on the basis of reducing the communication power consumption of a portable device (for example, an earphone or a charging box), but also reducing the volume of the portable device and simplifying the structure, such that the user experience is improved.
