DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIG. 4, a surface material 1 is woven with appropriate yarns. The surface material 1 can be manufactured to a diaphragm in accordance with the present invention, such as the damper F shown in FIG. 2 and the cone paper E shown in FIG. 3, through resin dipping, drying, molding and trimming processes.
Referring to FIG. 5, the surface material 1 of the present invention is woven with a plurality of yarns 10 using any available weaving technologies. The structure of the surface material 1 is similar to the conventional knitwear structure and may print various patterns and stripes thereon.
FIG. 6 shows the structure of the surface material 1 according to the present invention. The surface material 1 is woven with a plurality of metal yarns 10 not conventional pure yarns. The metal yarn 10 comprises a plurality of metal wires 102 and a plurality of yarns 101 interfused and entwisted together.
The structure of the metal yarn 10 may have different types. For example, FIG. 7 shows the metal yarn 10 comprises one metal wire 102 and a plurality of yarns 101 entwisted around the metal wire 102 according to a first embodiment of the present invention; FIG. 8 shows the metal yarn 10 comprises one metal wire 102 and a plurality of yarns 101 entwisted around one yarn 101 according to a second embodiment of the present invention; and FIG. 9 shows the metal yarn 10 comprises three metal wires 102 and a plurality of yarns 101 entwisted around one yarn 101 according to a third embodiment of the present invention. The quantity of the metal wires 102 and the yarns 101 can be adjusted according to the actual demands. Therefore, the metal yarn 10 may be woven into the surface material 1 for further manufacturing the diaphragm.
FIGS. 7-9 show the different structure of the metal yarns, respectively. However, they have a common characteristic that the quantity of the metal wires 102 is less than that of the yarns 101, so that the diaphragm can keep appropriate flexibility and elasticity. When the quantity of the metal wires 102 is larger than that of the yarns 101, the diaphragm might be over rigid.
According to the present invention, the diaphragm has the metal wires; thereby the strength, availability and tearing resistance of the diaphragm can be increased. And it has more durable than the conventional diaphragm and can improve the quality of speakers.
While the present invention has been described by way of example and in terms of preferred embodiments, it is to be understood that the present invention is not limited thereto. To the contrary, it is intended to cover various modifications and similar arrangements as would be apparent to those skilled in the art. Therefore, the scope of the appended claims should be accorded the broadest interpretation to encompass all such modifications and similar arrangements.
