For example, a portable electronic device can be electrically connected to a power bank through a cable for charging. Alternatively, the portable electronic device can be electrically connected to a headphone device via the cable for propagating audio signals to headphone terminals.


Since the cable is often stretched or pulled accidentally or unexpectedly, the chance of damaging the cable is extremely high. The user needs to repair or replace the cable frequently, which obviously causes extra expenditure to the user and the usage inconvenience. Therefore, how to improve the strength resistance of cables is obviously one of the important topics in the field.

For example, the other end of the second sub connecting cable 20b is electrically connected to an electrical component 30a and an electrical component 30c, the other end of the third sub connecting cable 20c is electrically connected to an electrical component 30b, and the present disclosure is not limited thereto. In other words, the cable device 100 can have multiple connecting cables 20 and the control element 23 according to the requirements for increasing functional features of the cable device 100, and the present disclosure is not limited by the embodiment of FIG. 5.


In the embodiment of FIG. 5, the cable device 100 is illustrated as a headphone device. Therefore, the first connector 10 in the embodiment is used as TRS connector for being electrically connected to the electronic device. In the embodiment, the first sub connecting cable 20a is configured to have the control elements 23a and 23b, the control elements 23a and 23b are used to control the volume of the headphone device, such that the user can control the volume by the control elements 23a and 23b.

The control element 23 mentioned above can be implemented by touch textile, but such implementation is not intending to limit the present disclosure. Referring to FIG. 6, the control element 23′ can be constructed by weaving signaling yarn 24 having no insulating layer and second textile 25. In the embodiment of the FIG. 5, the signaling yarn 24 of the control element 23a or 23b disposed within the first sub connecting cable 20a is electrically connected to the conductive wire element 22 of the first textile 21 for propagating the electric signals and electrical energy.


Referring to FIG. 6, one end of the signaling yarn 24 receives a scan signal SCAN transmitted from the electronic device (or electrical component 30a, 30b), and the electronic device (or electrical component 30a, 30b) receives a touch sensing signal SENSE transmitted from the other end of the second signaling yarn 24 for determining whether there is a touch object 200 (a finger or other touch object) that touches the control element 23.


In the embodiment, because the signaling yarn 24 has no insulating layer to cover thereto, the resistance generated by the touch object 200 touching the control element 23 will change the touch sensing signal SENSE. Therefore, the electronic device can determine whether there is a touch object 200 that touches the control element 23 according to the touch sensing signal SENSE (in other words, the control element 23 is provided as resistive touch sensing element in the embodiment).


An embodiment for implementing the signaling yarn 24 which has no insulating layer of the present disclosure will be further described below. Please referring to FIG. 7 and FIG. 8, FIG. 7 is a three-dimensional schematic diagram of the signaling yarn 24 according to an embodiment of the present disclosure, and FIG. 8 is a sectional schematic diagram of signaling yarn 24 according to an embodiment of the present disclosure. As shown in FIG. 7 and FIG. 8, the signaling yarn 24 has a staple fiber 221 and a sheet conductor 222. The staple fiber 221 is provided as a supporting material for supporting the sheet conductor 222 enlacing thereto. The sheet conductor 222 is enlacing the surround surface of the staple fiber 221 in a spiral extending manner to increase a strength resistance of the signaling yarn 24.


Please refer to FIG. 9, and FIG. 9 is a flow chart of a manufacturing method of the cable device 100 according to an embodiment of the present disclosure. First, in step S71, a conductive wire element 22 is provided.

Second, in step S72, a connecting cable 20 is prepared, wherein the connecting cable 20 has a first textile 21 and at least one conductive wire element 22 disposed within the first textile 21. In an embodiment of the preset disclosure, in the step S72, at least one control element 23 is configured to have the connecting cable 20, and the at least one control element 23 is electrically connected to the at least one conductive wire element 22. In the final step S73, one end of the connecting cable 20 is electrically connected to first connector 10, and the other end of the connecting cable 20 is electrically connected to electrical component 30. More specifically, one end of the conductive wire element 22 is electrically connected to the first connector 10, the other end of the conductive wire element 22 is electrically connected to electrical component 30, one end of the first textile 21 is connected to the first connector 10, and the other end of the first textile 21 is connected to electrical component 30. Therefore, the cable device 100 according to the embodiment of the present disclosure is implemented according to the manufacturing method mentioned above.


As mentioned above, because the conductive wire element 22 of cable device 100 of the present disclosure is disposed with the first textile 21 in the wavy manner, the conductive wire element 22 can be stretched accompanying with first textile 21 and will not be broken due to the external force. In addition, in the embodiment that the signaling yarn is provided as the conductive wire element 22 of the present disclosure, the staple fiber 221 of the signaling yarn having strength between 26S and 40S is provided as the support material, and the sheet conductor 222 of the signaling yarn is enlacing the surrounding surface of the staple fiber 221 to increase the strength resistance of signaling yarn. The conductive wire element 22 of the present disclosure not only propagates the electric signals and electrical energy, but also has a better strength resistance. Therefore, the conductive wire element 22 will not easily be broken, and the life time and the strength resistance of the cable device 100 can be increased correspondingly.


While the present disclosure has been described by means of specific embodiments, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of the present disclosure set forth in the claims.
