  • Patent number: 10587955
    Abstract: The present invention provides a method for making a speaker vibrating member, including: impregnating a fiber cloth with a resin solution for at least one time; removing the fiber cloth from the resin solution, and impregnating the fiber cloth with a water-based rubber solution for at least one time; drying the fiber cloth; forming at least one speaker vibrating member shaped portion on a dried fiber cloth; and cutting the at least one speaker vibrating member shaped portion off from the dried fiber cloth to acquire the speaker vibrating member. In such a way, the fiber cloth may be prevented from sticking with the mold during the formation step due to the protection provided by the release layer. In addition, the speaker vibrating member manufactured by the method has a higher flexibility and a remarkable fatigue resistance; consequently, the sound quality of the speaker may be enhanced.

  • Patent number: 10225658
    Abstract: An elastic composite structure for a speaker vibrating member, includes a vibrating member body, a resin base material and a gum material. The vibrating member body is provided with fibers that are interwoven with each other. The resin base material is coated over an outer side of the fibers for the fibers to keep a predetermined stiffness. The gum material is coated over and combined with the resin base material to form the elastic composite structure to maintain a predetermined resilience and ductility of the fibers. With such a structure, the resonance noise generated during the vibration of resin base material and speaker vibrating member may be reduced.
