Abstract: An audio processing system includes an input unit, a control unit, an audio reproducing unit, an I/O processing unit, and a switch unit. The input unit receives instructions from a user and generates a first signal or a second signal in response to the instructions. The control unit generates a first trigger signal or a second trigger signal according to the first signal or the second signal, respectively. According to the first trigger signal, the audio reproducing unit decodes a plurality of audio files into internal audio signals, and the I/O processing unit selectively outputs the internal audio signals to a first external device. According to the second trigger signal, the I/O processing unit selectively inputs external audio signals from a second external device, and the switch unit disables a connection between the audio reproducing unit and the I/O processing unit.

Abstract: An LED illumination system includes an LED lamp, a voltage stabilizing circuit and a control circuit. The LED lamp includes an LED string which has a plurality of LEDs connected in series. The voltage stabilizing circuit connects the LED lamp for supplying an electric current to the LED string. The control circuit includes an MCU and a MOSFET connected between the MCU and the LED string. The MCU detects the electric current flowing through the LED string and outputs a PWM signal which has a frequency within a range from 60 Hz to 500 Hz to the MOSFET. The MOSFET receives the PWM signal from the MCU and turns on and off repeatedly under a control of the PWM signal, to make a flicker frequency of the LEDs of the LED string be within a predetermined range.

Abstract: An audio device includes a jack, a switch, an amplifier, an internal sound producer, and a determining circuit. The jack establishes a connection with an external sound producer. The switch is in an opened state when the connection is established, and in a closed state when the connection is open. The amplifier amplifies audio signals to amplified audio signals and sends the amplified audio signals to the switch. The determining circuit receives the amplified audio signals from the switch, and generates a high voltage to control the amplifier not to output the amplified audio signals to the internal sound producer when the switch is in the closed state, and generates a low voltage to control the amplifier to output the amplified audio signals to the internal sound producer. The determined circuit further filters out the amplified audio signals when the switch is in the opened state.
