Each of the filters filters a first signal to generate a second signal. The speakers are arranged so that transfer characteristics from the speakers to an evaluation point are different from each other. Each of the speakers converts the second signal generated by a corresponding one of the filters into a sound wave. The sound collection unit combines sound waves output from the speakers to generate a combined sound wave. The filters are formed so that a transfer characteristic from the first signal to an output signal matches a target transfer characteristic, the output signal indicating a sound pressure of the combined sound wave at the evaluation point."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Speaker system having a sound collection unit for combining sound waves","description":"According to an embodiment, a speaker system includes filters, speakers, and a sound collection unit.
