An audio device is characterized in that, with sound field correction as a precondition, low-pitch ranges can be reproduced by using numerous small-diameter speakers, a single one of which is insufficient to reproduce low-pitch ranges despite good group delay characteristic, and outstanding waveform reproducibility can be achieved by covering the periphery of the speakers with sound-absorbent material so as to remove noise emitted by surfaces other than the front surface of cone paper."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for evaluating audio device, audio device and speaker device","description":"A method and apparatus for evaluating audio device for evaluating performance of an audio device by inputting into the audio device an audio signal having a waveform in which a plurality of waves with","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10477334","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
