The hollow frame includes a hollow portion, a top surface, and a bottom surface. The diaphragm includes a central portion and an outer peripheral portion surrounding the central portion. The voice coil is coaxially held in the hollow portion. The voice coil includes a top edge fixedly connected to the central portion and a bottom edge. The elastic damping piece includes an outer fixing member connected to the hollow frame, an inner fixing member connected to the voice coil, and an elastic piece body connected between the outer fixing member and the inner fixing member. The magnetic circuit assembly is held in the hollow portion and is in the voice coil but not in contact with the voice coil."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Micro-speaker","description":"The micro-speaker includes a hollow frame, a diaphragm, a voice coil, an elastic damping piece, and a magnetic circuit assembly.
