Abstract:
An integrated controller for electronic apparatuses includes a host and an AC/DC converting module. The host includes at least one power terminal set to connect to an electronic apparatus. The power terminal set includes a power input terminal, a power output terminal and a power neutral terminal. The power input terminal is connected to a fire wire to receive AC power. The power output terminal is connected to a wire-input end of the electronic apparatus, and the power neutral terminal is connected to a wire-output end of the electronic apparatus. Therefore, the AC/DC converting module receives the AC power via the power input terminal and the power neutral terminal and converts the AC power to DC power which is required by the integrated controller. The integrated controller is mounted in an original position for a wall-embedded switch is positioned to replace the wall-embedded switch.
Abstract:
A speaker structure includes a speaker box, a speaker unit, and an elastic component. An air pressure inside the speaker box is lower than that outside the speaker box. The speaker unit is disposed on the speaker box and includes a first vibrating assembly. The elastic component is disposed in the speaker box and connected to the first vibrating assembly and the speaker box in the speaker unit. When the speaker unit operates, the first vibrating assembly of the speaker unit vibrates, and the elastic component produces a pre-force correspondingly, the total pressure of the pre-force and the air pressure inside the speaker box equals to the air pressure outside the speaker box to balance the first vibrating assembly at an equilibrium position.
Abstract:
An electronic device includes an energy collection circuit, a rectifier circuit, and a control unit. The energy collection circuit receives an energy signal transmitted via transmission frequency from a wireless charger base. The rectifier circuit generates a drive voltage according to the energy signal. The control unit compares the drive voltage with a reference voltage, and compares the transmission frequency with a reference frequency. When the drive voltage is less than or equals to the reference voltage, or when the transmission frequency is lower than or equals to the reference frequency, the control unit outputs position deviation information. The electronic device detects the efficiency of the wireless charging, and reminds the user whether the position of the electronic device needs to be adjusted, which ensures an efficient charging.

Abstract:
A switching power supply circuit is disclosed in an embodiment. The switching power supply circuit includes a power output stage, a pulse width modulation (PWM) signal generator, a compensation module, and a overshooting protection module. The power output stage is used for generating an output signal to drive a load device. The PWM signal generator generates a pulse width modulation (PWM) signal which is used for controlling the power output stage. The compensation module is used for generating a compensation signal to the PWM signal generator according to the output signal. The overshooting protection module receives the output signal to enable or disable the PWM signal generator.
Abstract:
An electronic device and a method for recognizing output power of a power supply thereof are provided. The electronic device includes a host and a power supply. The power supply is coupled to the host, receives an input power and converts the input power to a supplied power. The power supply transmits the supplied power to the host, and loads a notification signal to the supplied power in at least a time period. The acknowledge signal is a periodic clock signal, and corresponds to the output power of the power supply. The power supply loads the acknowledge signal to the supplied power in one or more time periods, and transmits the acknowledge signal to the corresponding host. The host can get the output power of the power supply via the acknowledge signal, which can improve efficiency and security of the supplied power.
