In the balanced mode, an analog audio data is amplified by an amplifier 8, a negative-phase data of the analog audio data is amplified by an amplifier 9, and the amplified analog audio data and the amplified negative-phase data are mixed so as to be output. In the ACG mode, the analog audio data is amplified by the amplifier 8 and ground is maintained by the amplifier 9. The CPU 2 decreases volume of the analog audio data that is output in the balanced mode compared with volume of the analog audio data that is output in the ACG mode."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Music reproducing device","description":"To be easy for a user to judge difference of sound quality of an audio signal that is output in a balanced mode and sound quality of the audio signal that is output in an active control ground mode.A ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9774950","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.
