The micro speaker is assembled from a vibrating diaphragm assembly and a magnetic assembly which is inter-assembled with the vibrating diaphragm assembly. The vibrating diaphragm assembly separates the accommodation space into a front chamber and a rear chamber which are not interconnected; whereas, the front chamber is connected with the sound hole. Therefore, water vapor outside the micro speaker unit can be prevented from entering into the rear chamber and the micro speaker by the vibrating diaphragm assembly, thereby improving the waterproof effect of the entire micro speaker unit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Micro speaker unit with a waterproof effect","description":"The present invention discloses a micro speaker unit with a waterproof effect, including an outer casing which is provided with an accommodation space and a sound hole, and a micro speaker which is in","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11277693","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.
