Abstract
A method for transmitting information, a communication device, a portable device and a communication system are provided. The method is applied to a portable device; and the method includes: receiving and/or transmitting information in an electric field coupling manner through a first coupling electrode disposed at the portable device and a second coupling electrode at an opposite end. In an embodiment of the present application, the information is received and/or transmitted through an electric field coupling manner, which could not only improve communication quality and connection reliability on the basis of reducing communication power consumption of a portable device (such as an earphone or a charging case), but also reduce a volume of the portable device, simplify a structure and further improve user experience.
