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.

Array microphone system including omni-directional microphones to receive sound in cone-shaped beam

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.

Electronic device with internal array microphone affixed to rear cover of display

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.
