The acoustic device separates the accommodation space into a front cavity and a rear cavity. The first air-permeable separation component is fixed inside the housing and separates the rear cavity into a first rear cavity and a second rear cavity in air communication with each other. The acoustic device is located in the first rear cavity. The second rear cavity is filled with acoustic absorption particles. The second air-permeable separation component separates the second rear cavity into at least two rear sub-cavities in air communication with each other. Types of the acoustic absorption particles filled in two of the rear sub-cavities are not completely the same. Acoustic performance of the speaker box in the present disclosure is better."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Speaker box","description":"The present disclosure provides a speaker box, including a housing having an accommodation space, an acoustic device accommodated in the accommodation space, a first air-permeable separation component","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10484769","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.
