A throat according to an embodiment includes a first side wall, a second side wall, a third side wall, and a fourth side wall. A third opposing surface of the third side wall and a fourth opposing surface of the fourth side wall are each formed into a curved surface having a convex portion and a concave portion. The convex portion and the concave portion are so disposed as to oppose each other, and the convex portion and the concave portion are so disposed as to oppose each other. Amplitudes of the curved third opposing surface and the curved fourth opposing surface gradually decrease along a direction from a reference center line to a first opposing surface or a second opposing surface."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Throat and speaker system","description":"Provided is a throat and a speaker system that can properly correct a path length of a sound wave.
