Problems solved by technology

However, the existing trunk lines (such as aluminum copper wires and alloy copper wires) are prone to softening and disconnection due to excessive temperature
At the same time, due to the limited tensile strength of the trunk line itself, when the power of the speaker is increased and the long-term operation is added, the trunk line is prone to insufficient stress and metal fatigue to cause fracture

Embodiment Construction

[0020] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.

[0021] Figure 1 to Figure 3 A trunk line in the present invention is shown, the trunk line has a simple structure, uses less materials, and has few specifications and good versatility. And compared with general chemical fiber lines, the trunk line contains non-water-absorbing and high-temperature-resistant resin, which makes the trunk line have better performance and longer service life. In addition, the trunk line has a simple structure and better consistency. Moreover, the resistance matching difference of the trunk line is less, so that it is not easy to generate high temperature at the welding point, thereby avoiding the situation of disconnection due to excessive temperature, and further improving the service lif...

Abstract

The invention discloses a trunk line which comprises an elastic body and a winding line, wherein the elastic body is arranged in the center, the winding line is spirally wound around the elastic body, the elastic body comprises an elastic line which is arranged in the center, an insulating layer is wrapped on the elastic line, and a glue layer which is used for bonding the elastic body and the winding line each other is wrapped on the insulating layer. According to the technical scheme of the trunk line, the structure of the trunk line is simple, and the winding line is spirally wound around the elastic body of the trunk line, so that the bending fatigue resistance, the heat resistance and the high-temperature and high-humidity resistance of the trunk line can be increased, the tension resistance of the trunk line is increased, the service life of the trunk line is prolonged, a voice coil with the trunk line can bear higher rated power, and the risk of disconnection is reduced.

Description

technical field [0001] The invention relates to the field of loudspeakers, in particular to a trunk line. Background technique [0002] Common electro-acoustic products on the market are mainly dynamic speakers. But these loudspeakers all generally have the problem that the service life is not long. When this type of speaker is working, a high-frequency current passes through the voice coil coil to generate a magnetic field, and the voice coil wire of the voice coil is connected to the trunk line to produce sound. However, existing trunk lines (such as aluminum copper wires and alloy copper wires) are prone to softening and disconnection due to excessive temperature. At the same time, due to the limited tensile strength of the trunk line itself, when the power of the speaker is increased and the long-term operation is added, the trunk line is prone to insufficient stress and metal fatigue to cause fracture. Contents of the invention [0003] The technical problem to be ...
