Sense circuits inside the electronic device may be alternately coupled through the multiplexer and first audio amplifier so that, in a first mode of operation, the multiplexer couples the audio signal to the first audio output terminal, and in a second mode of operation, the multiplexer couples an analog voltage corresponding to an internally sensed value to the first audio output terminal. Use of the audio connector and audio circuitry to access internal electrical parameters may facilitate testing and analysis of internal systems."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Audio interface circuits and methods","description":"In one embodiment, an electronic device includes an audio connector port comprising a ground terminal and one or more audio output terminals, a first audio amplifier coupled to one of the audio output","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9685916","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.
