Computer peripheral device with the functions of a radio, a microphone, and a mouse

A computer peripheral device with the functions of a radio, a microphone, and a mouse comprising:

• a USB control interface having a USB port for connecting to a computer;
• a mouse circuit connected to the USB control interface for outputting a mouse coordinate signal;
• and
• a radio circuit connected to the USB control interface, the radio circuit consists of a phase lock loop, a frequency modulation circuit, an antenna, and an audio processing unit, wherein
• the phase lock loop is connected to the USB control interface for receiving the commands from the USB control interface and controlling the frequency modulation circuit;
• the frequency modulation circuit is connected to the phase lock loop, the frequency modulation circuit consists of an amplifier, a mixer, and a demodulator, the amplifier serves to amplify the signal received by the antenna, and then signal passes through the mixer for generating a medium frequency (MF) signal, then the MF signal is amplified and passes through a demodulator for being demodulated as a pulse frequency signal;
• the antenna is connected to a frequency modulation circuit and serves to receive the electromagnetic wave of a broadcasting station;
• the audio processing unit is connected to the frequency modulation circuit, the audio processing unit consists of an amplifier, a filter, and an analog to digital converter;
• the audio processing unit serves to process the pulse frequency signal and then output the signal to the USB control interface, and then the digitized audio signal is sent to the computer for being converted as audio for being outputted;
• if the audio processing unit neglect the analog to digital converter, then the analog audio signal may be sent to the computer through the USB control interface;
• and
• the microphone circuit is connected to the audio processing unit, the microphone circuit serves to pick up voice signals, then after processed by the audio processing unit, the digitized audio signals are sent to the computer for being converted into voices for being outputted.
