An upper end of the voice coil is fixed to the diaphragm. The magnetic structure is arranged under the voice coil. A monolithic, one-piece voice-coil balancing system is fixed under the frame body. The monolithic, one-piece voice coil balancing system is composed of two symmetrically arranged dampers connected to an integrally formed support frame. The two dampers and the support frame are made of a flexible circuit board. Each of the two dampers comprises a first end, a second end and a cantilever connecting the first end and the second end. A ratio of a length L of the cantilever to a distribution distance D of the cantilever is between 2-15."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Micro-speaker and damper for micro-speakers","description":"A micro-speaker includes a frame body, a diaphragm arranged on the frame body, a magnetic structure and a voice coil arranged in the frame body.
