AI Technical Summary
Conventional acoustic devices, including cone and dome speakers, suffer from phase shift and inconsistency due to the volume of air masses required for operation, leading to parasitic harmonics and distortion in sound reproduction, especially when deviating from the tuned frequency.
A flat loudspeaker design featuring a resonant excitation membrane with a specific aspect ratio, honeycomb structure, and non-uniform stiffness, attached to a support frame using foam tape, and equipped with strategically placed electrodynamic vibration exciters, optimized to distribute resonant modulations uniformly across the membrane for improved sound quality.
The solution achieves a significant improvement in sound reproduction quality by minimizing phase shifts, reducing harmonic distortions, and ensuring a wide frequency range with minimal labor and material costs, allowing for the generation of the entire audible sound spectrum with reduced harmonic distortion.
