Abstract

The invention provides a charging circuit and an electronic device. The charging circuit comprises a circuit board. The circuit board is provided with a first general electrode, a second general electrode and at least one electrostrictive module. The electrostrictive module comprises a first inductive electrode, an electrostrictive material layer and a second inductive electrode which are sequentially superposed; The first sensing electrode is connected with the first general electrode and the second sensing electrode is connected with the second general electrode; The circuit board comprisesan insulating medium; The electrostrictive material layer is embedded in the insulating medium. Thus, the electrostrictive module in the charging circuit can receive the ultrasonic signal and convertthe ultrasonic signal into the AC target voltage signal. The charging distance is long, and the user can charge the electronic equipment when using the same, which is convenient and fast.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a charging circuit and electronic equipment. Background technique [0002] When charging electronic devices, wireless charging technology can be used. In the prior art, the principle of electromagnetic induction is generally used to realize wireless charging. When charging, the electronic device needs to face the internal coil of the charger. With the existing wireless charging technology, the wireless charging distance is relatively short, generally at the centimeter level. When the user uses the electronic device, it cannot be charged at the same time, which is very inconvenient. Therefore, in the prior art, when wirelessly charging an electronic device, the charging distance is relatively short. Contents of the invention [0003] Embodiments of the present invention provide a charging circuit and an electronic device, so as to solve the problem in the prior art that...
