Abstract: An unloading system includes a casing, a conveying device, a capturing device and a control device. A first entrance, a first exit and a second exit are formed on the casing. The conveying device is for conveying a carrying component and a circuit board disposed on the carrying component from the first entrance. The capturing device is for capturing the circuit board and then conveying the circuit board to the first exit. The control device is electrically connected to the conveying device and the capturing device. The control device is for controlling the capturing device to capture the circuit board entering from the first entrance and then to convey the circuit board to the first exit. The control device is further for controlling the conveying device to convey the carrying component from which the circuit board is unloaded to the second exit.

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: An electronic device includes a display, a plurality of chambers, and a microphone array. The display includes a front cover and a rear cover affixed to the front cover. The plurality of chambers is formed on the rear cover. The microphone array includes a plurality of microphones disposed in the chambers.

Abstract: An electronic device includes a housing, a uni-directional microphone, and a cover. The housing has a first acoustic opening and a second acoustic opening. The uni-directional microphone is disposed in the housing to receive external sound via the first acoustic opening and the second acoustic opening. The cover is disposed in the housing to cover the first acoustic opening, the second acoustic opening, and the unidirectional microphone. A process for mounting a microphone includes providing a first acoustic opening and a second acoustic opening on a housing, fixing a uni-directional microphone in the housing beside the first acoustic opening, and covering the first acoustic opening, the second acoustic opening, and the uni-directional microphone with a cover.
