AB  - Variable directivity speaker arrays are very popular in many acoustic aspects, such as wearable systems, natural sources simulations or acoustic scanners. Standard systems constructed from traditional drivers, despite great DSP, have limited beamforming possibilities because of the very narrow directivity patterns for loudspeakers in high frequencies. This paper presents a new approach for micro-speakers array design from monopole sources, based on isobaric speaker configuration. New solutions allow to reach high efficiency in broadband frequency range keeping matrix size small. This presentation will contain an explanation of used isobaric speaker principles and comparisons between standard transverse transducers matrix and innovative point-source matrix in two configurations. Achieved results allow to improve beamforming effectiveness in a high frequency range with new driver matrix construction.
