Hybrid Speaker Array Optimizing Wavefront Reproducibility

The patent applies local quality by differentiating the functional roles of speakers in different spatial regions. General speakers are deployed in the inner region where cost-effectiveness is prioritized, while higher order speakers are strategically placed in the outer region where enhanced wavefront reproduction is more critical. This spatial differentiation of speaker types and functions resolves the contradiction by optimizing the balance between reproducibility and cost through region-specific quality allocation.

The patent segments the sound field reproduction system into two distinct spatial zones: an inner region handled by general speakers and an outer region handled by higher order speakers. This segmentation allows the system to use fewer expensive higher order speakers while maintaining overall reproducibility, as each region is optimized for its specific speaker type. The segmentation principle resolves the contradiction by distributing functional requirements across different spatial domains rather than uniformly deploying expensive components throughout.

The patent merges two different speaker types (general speakers and higher order speakers) into a unified hybrid system that leverages the strengths of each. General speakers provide cost-effective coverage for the inner region, while higher order speakers enhance wavefront reproduction in the outer region. This merging approach resolves the contradiction by creating a synergistic system where inexpensive components handle routine functions and expensive components provide specialized capabilities where needed, achieving both cost reduction and maintained adaptability.
