Description

Signal line

Technical Field

The utility model belongs to the technical field of the connecting wire, especially, relate to a signal line.

Background

The signal line is a wire used for transmitting sound signals generated by a sound source (signal source), and is commonly used for equipment such as a loudspeaker, and the signal line has the greatest defect that the loudspeaker emits sound by vibration of drum paper, so that when the loudspeaker emits sound, the signal line in the loudspeaker also generates vertical vibration along with the vibration of the drum paper, and when an audio signal rises to a certain frequency, the signal line generates transverse vibration or circular vibration in the horizontal direction besides the vertical vibration, namely, a rope skipping (roping) phenomenon is formed; when the signal wire in the loudspeaker generates a rope skipping phenomenon, the signal wire not only is easy to hit drum paper or bounce waves to generate noise, but also can form a short circuit of an audio signal due to the fact that the signal wire is touched; if the tensile strength of the signal line is insufficient, the signal line is likely to be broken by vibration.

Meanwhile, as the core of each strand of braided wire in the audio signal conducting wire for conducting the audio signal in the loudspeaker is surrounded by the conducting layers with the same winding direction, after the braided wires are braided or wound into the audio signal conducting wire, the structural hardness of the formed audio signal conducting wire is insufficient. Therefore, the rope skipping phenomenon is easy to occur during vibration to touch the drum paper or the elastic waves of the loudspeaker.

In addition, although the braided wire formed by the core and the two conductive layers wound around the core in opposite directions in layers can be adopted to make the audio signal conducting wire formed by the braided wire have better hardness, the formed audio signal conducting wire is still easy to generate rope skipping phenomenon under high-frequency vibration due to insufficient flexibility of the braided wire.

For example, U.S. patent No. 5,125,473 discloses an improved loudspeaker damper, in which an audio conducting member for conducting an audio signal is fixed to the damper, thereby preventing the audio conducting member from being broken due to insufficient tensile strength; alternatively, as in taiwan patent publication No. 408897, the arrangement of the audio signal conducting wire is directly abandoned, and the metal conducting layer is plated on the upper end surface or the lower end surface of the damper by vacuum plating, and is electrically connected to the voice coil to replace the existing audio signal conducting wire, thereby avoiding the occurrence of rope skipping and eliminating noise.

However, in each of the above methods, a number of complicated steps are required to be added to the plating of the metal conductive layer on the damper or the fixing of the audio conducting member on the damper. Moreover, improper control may further reduce the audio signal transmission effect, thereby increasing the manufacturing difficulty. Meanwhile, the method is extremely high in cost, so that the method is not beneficial to the use in the industry. Therefore, the need in the art should still be met by improving the structure of the audio signal conducting wire.

Therefore, how to provide a high frequency signal conducting wire to effectively increase the structural rigidity or Damping (damming) constant of the high frequency signal conducting wire and avoid the occurrence of rope skipping phenomenon has become an important issue for improving the quality of the speaker, and is also an objective of the development in the field.
