The time-varying signal generation and comparison circuits are connected to the first connection point. When the audio plug is inserted into the audio jack, the first connection point is connected to a first pole of the audio plug and the second connection point is connected to a second pole different from the first pole of the audio plug. Therefore, the time-varying signal generation circuit, the first connection point, an inner impedance circuit of the audio plug and the second connection plug form a loop. The comparison circuit outputs a determination signal indicating the audio plug is inserted by detecting a change of a time-varying signal generated by the time-varying signal generation circuit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Audio plug detection structure in audio jack corresponding to audio plug and method thereof","description":"An audio plug detection structure is disclosed, which is adapted for an audio jack corresponding to an audio plug and includes a first and second connection points, a time-varying signal generation ci","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9813816","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.
