The loudspeaker module of the present invention is provided with inverted tube in communication with rear acoustic cavity, so that low-frequency acoustic effect of products can be enhanced, and heat dissipation of rear acoustic cavity and balance of atmospheric pressures can be achieved; inverted tube and loudspeaker unit share front acoustic cavity and sound hole, which is beneficial to increasing size of loudspeaker unit and improving acoustic performance of products."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Loudspeaker module","description":"Disclosed is a loudspeaker module, which comprises a loudspeaker unit and a peripheral frame comprising an upper housing and a lower housing; a front acoustic cavity and a rear acoustic cavity are res","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9756416","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.
