The present disclosure provides speaker device. speaker device includes frame, vibration unit fixed to frame and magnetic circuit unit driving vibration unit to vibrate and produce sound, where magnetic circuit unit is provided with magnetic gap; vibration unit includes diaphragm fixed to frame, holder fixed to diaphragm by injection molding and voice coil inserted in magnetic gap and connected to holder; holder includes bottom wall that is fixed to diaphragm and provided with pair of long edges and pair of short edges, and pair of side walls bending and extending from outer peripheries of short edges of bottom wall to magnetic circuit unit; side walls each are provided with chamfered portions on sides close to long edges. Present disclosure solves problem of deformation of holder molded in mold, thereby improving evenness of holder after molding.

A weaved fabric, a weaving method, and a soft component of a speaker made from the weaved fabric or fabric manufactured by the weaving method are provided. The weaved fabric has multiple larger meshes and multiple smaller meshes and each one of the larger meshes is surrounded by six smaller meshes. The weaving method can manufacture a fabric with the larger meshes and the smaller meshes. With the yarns forming the larger meshes and the smaller meshes and the larger meshes and the smaller meshes forming a resilience structure, the resilience and evenness of the fabrics are improved and the porosity of the fabrics is higher. Therefore, with a soft component made from the fabrics, tensions on the fabrics may keep even during working, and the amplitudes in the positive direction and the negative direction are more symmetrical.
