The speaker unit separates the containment space into a front acoustic cavity and a back cavity, the sound outlet is communicated with the front acoustic cavity and forms a front cavity together. The invention also provides a mobile terminal. Compared with the related art, the sounding device and the mobile terminal of the invention have better reliability and better performance."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Sounding device and mobile terminal","description":"The invention provides a sounding device having a housing body with a containment space, a sound outlet formed in the housing body, a speaker unit fitted in the housing body, an intake valve that comm","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11290793","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.
