INTERACTIVE SCHOOL DESK AND CHAIR MODULE WITH SEATING DETECTION, DIFFERENTIAL NEAR-FIELD AUDIO SELECTION, AND DIRECTED AUDIO OUTPUT.

Abstract

The invention relates to an acoustic interaction module (4) for providing local vocal interaction with the student in crowded classroom environments; this module includes a student sound input aperture (5) oriented towards the student use area (27), a first acoustic sound input channel (6) and a first microphone (7), a different directional ambient reference sound input aperture (8), a second acoustic reference channel (9) and a second microphone (10), an acoustic separator / barrier (11) that reduces the transition between acoustic paths, a seating sensor (14) that detects the presence of a student and a control unit (13) that differentially evaluates the microphone signals, and the acoustic interaction module (4) that enables the sound to be transmitted to the student to be directed to the student use area (27) via the loudspeaker (15) and the personal sound output channel (16).
