Abstract:
A method for controlling a screen of a terminal, includes: determining a real-time state of the screen as a first state; generating a first electromagnetic signal corresponding to the first state, and sending the first electromagnetic signal to a metal structure on a surface of the terminal through a first human body communication component, such that the first electromagnetic signal is transmitted via a skin of a user; receiving, by the first human body communication component via the metal structure, a second electromagnetic signal sent by a wearable device associated with the terminal, the second electromagnetic signal being generated by the wearable device according to the first electromagnetic signal; and if the second electromagnetic signal includes state switching information regarding the screen, switching the real-time state of the screen from the first state to a second state.
Abstract:
A resonant rectifying device includes a transformer having a primary winding and a secondary winding, a primary-side circuit coupled to the primary winding of the transformer, and a secondary-side circuit coupled to the secondary winding of the transformer. The primary-side circuit includes a first field effect transistor (FET) and a second FET coupled in series between a voltage source and a ground, a capacitor, and an inductor. A first side of the capacitor is coupled to a point between the first and the second FETs. A second side of the capacitor is coupled to a first end of the inductor and one end of the primary winding. A second end of the inductor is coupled to the ground. The secondary-side circuit includes a third FET and a fourth FET coupled to a first end and a second end of the secondary winding, respectively.
Abstract:
The present disclosure relates to an earphone socket, an earphone plug, an earphone and an electronic device. For example, the earphone socket may include a socket body in which an earphone jack is formed. The earphone socket may include multiple ground terminals, which may be arranged in the earphone jack. The ground terminals may contact a ground section disposed on an earphone plug when the earphone plug is inserted into the earphone jack. The technical solutions of the present disclosure reduce earphone crosstalk and improve tone quality.
