AI Technical Summary

Technical Problem

Existing directional private sound transmission technology cannot meet the needs of multi-target parallel use. The beam content and parameter scheduling are limited, lacking adaptive adjustment capabilities, and the lateral dispersion of sound waves from external phone cases is a prominent problem.

Method used

A multi-beam adaptive ear-tracking privacy sound transmission device is adopted. The target position, posture and distance information are obtained through the sensing module, and the control module generates independent beam control signals to drive the directional sound array to form multiple highly directional narrow beam sound fields. The acoustic resonant cavity is combined to optimize the sound field focusing effect.

Benefits of technology

It enables multi-target parallel private sound transmission, independent beam scheduling and content isolation, and has adaptive closed-loop control capabilities, improving sound field stability and privacy, and reducing sound wave diffusion and leakage.
