Abstract: This application provides a switch power supply circuit and a terminal device, and the switch power supply circuit uses a second switch transistor to replace a diode in an asynchronous switch power supply circuit. A turn-on impedance of the switch transistor is very small, only tens of milliohms, so that a turn-on voltage drop in the switch power supply circuit is reduced from hundreds of millivolts to tens of millivolts, power loss of the switch power supply circuit is greatly reduced, and output efficiency is improved. Moreover, this solution uses a discrete component to form a control circuit to control a switch status of the second switch transistor without additionally setting a pulse width modulation (PWM) controller, and costs of the discrete component are far lower than costs of the PWM controller, reducing hardware costs of a switch power supply and simplifying a circuit design.

Abstract: This application discloses a wireless keyboard. The wireless keyboard includes a connection portion. The connection portion includes an accommodating cavity with an opening at an end and used for accommodating an electronic stylus. A wireless charging coil is arranged in the accommodating cavity. A charging interface and a wireless charging control module are arranged in the wireless keyboard. The wireless charging control module is connected to the charging interface and the wireless charging coil. The charging interface can receive a direct current signal. The wireless charging control module can convert, if it is detected that a direct current signal is inputted to the charging interface, the direct current signal into an alternating current signal and transmit the alternating current signal to the wireless charging coil. The wireless charging coil generates an alternating electromagnetic field in response to the alternating current signal, to wirelessly charge the electronic stylus.

Abstract: This application provides a signal transmission method and a related device. According to the signal transmission method, when two contact points on an electronic device are respectively in contact with two contact points on a keyboard, the electronic device may transmit a power signal and a GND signal to the keyboard through the contact points that are in contact with each other, that is, the electronic device may supply power to the keyboard. In addition, when a user presses a key on the keyboard to perform input, the keyboard may transmit key position information to the electronic device through a contact point that is in contact with the electronic device. In this signal transmission method, no Bluetooth chip needs to be built into the electronic device and the keyboard, reducing device costs.

Abstract: This application relates to a frame and an electronic device. The frame includes a first body and a second body. The first body includes a sealing surface, and the second body includes a flow-blocking part sunken toward one side. An extension surface of the sealing surface intersects the flow blocking part in a first direction. Because the flow blocking part is designed, in a plastic injection process, a pressure of injected plastic on the first body is reduced, to ensure that, after sealing processing is performed on the sealing surface of the first body, the plastic does not continuously flow in the first direction. This ensures sealing reliability of the sealing surface, improves sealing effect of the first body, enables the first body and the second body to be bound well, and ensures smooth manufacturing of the frame.
