Abstract: In an electronic apparatus, microphones are arranged parallel to one side of a display screen so as to be spaced apart from each other on the front surface of a display whose display screen is exposed. Together with the microphone, a microphone is arranged parallel to other side different from one side of the display screen. Of the microphones, the microphones are selected when one side of the display screen serves as a bottom, and the microphones are selected when other side of the display screen serves as the bottom. A voice input process is then executed.

Abstract: An acoustic antenna for computer workstation, used for video conferencing that comprises a plurality of microphones connected to a summator circuit. The microphones are distributed in a layout so as to form a substantially straight line and are each spaced with respect to a reference microphone placed in the vicinity of the vertical axis of symmetry of the screen of the workstation according to a specified law. The layout exhibits a substantially cylindrical directivity pattern whose axis of revolution is formed by the straight line.

Abstract: A phased array design in the shape of a logarithmic spiral. By distributing the elements of the array along a logarithmic spiral-shaped curve, spatial regularities are avoided and the array is therefore able to function over a wide frequency range.

Abstract: An end fire microphone array having reduced analog-to-digital converter requirements is disclosed. Analog filters are used to band-limit at least two secondary microphone elements which are spaced from a primary microphone element a distance respective of their band limited outputs. The band-limited secondary microphone outputs are combined by an analog summer and the primary microphone and combined secondary microphone signals are digitized by an analog-to-digital converter. A signal processor performs a super-directive analysis of the primary microphone signal and the combined secondary microphone signals. A steerable superdirective microphone array is disclosed. A plurality of microphones are arranged in a ring. The microphone outputs are digitized, split into frequency bands, and weighted sums are formed for each of a plurality of directions. A steering control circuit evaluates the relative energy of each directional signal in each band and selects a microphone direction for further processing and output.
