The vehicle approach warning apparatus includes a memory portion, a signal generation portion, a level adjustment portion, a signal synthesizing portion, and an amplifier. The memory portion stores a first sound source data for generating a signal of a low frequency component, and a second sound source data for generating a signal of a high frequency component. The signal generation portion generates the signal of the low frequency component, and the signal of the high frequency component. The level adjustment portion adjusts a level of the signal of the low frequency component and the high frequency component."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Vehicle approach warning apparatus","description":"A vehicle approach warning apparatus outputting a warning sound signal for outputting a warning sound, and generating the warning sound according to the warning sound signal from a speaker, and notify","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9648415","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.
