Problems solved by technology
How to reduce the impact of nonlinear characteristics on micro-speakers is an important issue to be considered in speaker design, but the geometric structure characteristics of existing surrounds determine that the compliance of diaphragm surrounds generally has nonlinear characteristics, which cannot be achieved by relying on traditional diaphragm designs. change the question
[0004] In the existing technology, when solving the problems of film folds and film cracks of the diaphragm while maintaining good low-frequency characteristics, it is often only possible to find a diaphragm material that is resistant to film folds, but it cannot learn from the existing diaphragm molding technology and physical vibration characteristics. It is a good solution to the problem of membrane folds and membrane cracks of the diaphragm
In addition, the realization of the concentricity of the loudspeaker system depends on the assembly and process, but there are inevitably problems such as assembly errors and material size tolerances, which make the concentricity of the vibration components deviate, thereby causing polarization

The invention discloses a vibrating membrane, a vibrating assembly and a loudspeaker monomer. The vibrating membrane comprises a membrane body and elastic components arranged around the center of the membrane body. The elastic components are arranged to exert elastic restoring force on the membrane body, and the direction of the elastic restoring force is perpendicular to the extending direction of the membrane body. The vibrating membrane has the advantage of being good in compliance. The vibrating assembly and the loudspeaker are provided with the vibrating membrane.
Description
technical field [0001] The present invention relates to the technical field of sound-generating devices, and more specifically, to a diaphragm, and to a vibrating assembly and a loudspeaker unit using the diaphragm. Background technique [0002] The diaphragm design of a microspeaker has always been an important factor in determining the performance of a microspeaker system. The geometric design of the diaphragm surround directly affects the acoustic performance of the microspeaker. As micro-speakers have higher and higher requirements for low-frequency characteristics, the problems faced by diaphragm design are becoming more and more severe. The nonlinear problem of microspeakers has always affected the performance of the speaker, and the compliance nonlinearity at the diaphragm surround is one of the main factors. Microspeakers with better low-frequency characteristics require the diaphragm and surround to provide good compliance, so that the performance can be extended ...
