  • Publication number: 20130257728
    Abstract: A multiplexed audio cable joystick includes plural keys, a key scanner, a frame format encoder, a transmission modulator, and a DAC. The key scanner is connected to the keys for scanning states of the keys to output pressed key information, The frame format encoder is connected to the key scanner for generating a frame transmission data according to the pressed key information. The transmission modulator is connected to the frame format encoder for performing a carrier modulation on the frame transmission data to generate a modulated transmission data. The DAC is connected to the transmission modulator for converting the modulated transmission data into an analog audio data. The transmission modulator has the same frequency band as an audio signal spectrum, and the frequency band has plural sub-bands, such that the transmission modulator modulates the frame transmission data into one of the sub-bands for transmitting data in multiplexing.

  • Patent number: 8508300
    Abstract: The present invention relates to audio amplifier and a method for protecting the audio amplifier. The audio amplifier includes a pre-amp circuit, an output stage power amplifier, a temperature detector and a gain adjusting circuit. The pre-amp circuit receives an audio signal for amplifying the audio signal to generate an amplified audio signal. The output stage power amplifier receives the amplified audio signal to drive a load. The temperature detector is used for detecting a temperature of the output stage power amplifier to output a temperature signal. The gain adjusting circuit adjusts amplitude of the amplified audio signal of the pre-amp circuit according to the temperature signal.

  • Publication number: 20050015260
    Abstract: An MP3 application device is provided. The MP3 application device comprises a host interface module, a playing module and a loudspeaker or a frequency modulation transmitter. Furthermore, a universal serial bus (USB) device or a memory card can be plugged into the MP3 application device. In this invention, the playing module issues a fetch instruction to read MP3 code data from the USB device or the memory card. An MP3 decoder with the playing module decodes the MP3 code data into voice data. The voice data is transmitted to the loudspeaker and broadcast. Alternatively, the voice data is sent to the frequency modulation transmitter and transmitted as wireless signals.
