    Abstract: An array microphone system includes a first omni-directional microphone, a second omni-directional microphone, a gain control, and a beam former. The first omni-directional microphone faces a first direction. The second omni-directional microphone faces a second direction opposing the first direction. When receiving sound, the first omni-directional microphone and the second omni-directional microphone respectively generate a first signal and a second signal. The gain control amplifies the second signal to transform into a third signal, wherein strength of the third signal is equal to that of the first signal when the sound comes from the first direction. The beam former separates an in-beam sound signal and an out-beam sound signal from the first signal and the third signal.

    Abstract: A communication device includes a Bluetooth module, an audio interface, a FM/AM radio wave module, and a microphone. The Bluetooth module receives a first audio signal. The audio interface receives a second audio signal. The first audio signal and the second audio signal are selectively sent out through the FM/AM radio wave module. The microphone receives a third audio signal which is selectively sent out through either the Bluetooth module or the audio interface.
