[0081] In the above embodiments, the noise canceling module and the audio source control module are integrated in the line controller of the earphone transmission line. But in practice, if the earphone transmission line itself does not have the sound control function, the line controller can only be equipped with the noise cancellation circuit of the noise cancellation module, and the sound source control function is controlled by the earphone user through the playback device. Please refer to Figure 4 , Figure 4 It is a schematic structural diagram of the earphone transmission line provided by the second embodiment of the present invention.

[0082] Figure 4 The difference between the earphone transmission line 4 of FIG. 1 and the earphone transmission line 1 of FIG. 1 lies in the architecture of the line controller 15 . Figure 4 The line controller 45 of the earphone transmission line 4 only includes the noise canceling module 153 and the battery 155 , and the noise ca...

[0085] The above-mentioned first connecting terminal may also be composed of a plurality of insulating parts, and the first microphone module may be disposed in one of the plurality of insulating parts according to requirements. Please refer to Figure 5 , Figure 5 A schematic structural diagram of the earphone transmission line provided by the third embodiment of the present invention is shown.

[0086] Figure 5 The difference between the earphone transmission line 5 and the earphone transmission line 1 in FIG. 1 lies in the structure of the first connection terminal 51 . The first connection terminal 51 of the earphone transmission line 5 includes a first terminal 111 , insulating parts 511 , 513 and a first microphone module 115 . The first terminal 111 protrudes from the insulating portion 511 . The insulating part 511 is electrically connected to the insulating part 513 via a transmission line. The insulating part 513 is electrically connected to the line controlle...

Abstract

A headphone cable and a plug thereof are provided. The headphone cable includes a first plug, a first microphone module, a first transmission line, a noise-cancellation module, and a second transmission line. The first plug has a first isolation portion with a first connector protruded thereon. The first connector is for plugging into a first headphone jack of a headphone. The first microphone module is disposed on the first isolation portion. The first transmission line has one end thereof connected to the first plug and the other end thereof connected to the noise-cancellation module. The second transmission line is connected to the noise-cancellation module and a playback apparatus. The noise-cancellation module generates a noise-cancellation signal to be combined with an audio signal being outputted to the headphone responsive to an environmental noise received through the first microphone module.

Description

technical field [0001] The present invention relates to a transmission line and its connection terminal, and in particular to an earphone transmission line with noise canceling function and its connection terminal. Background technique [0002] In recent years, the headset (Headphone) can be easily used by users of portable electronic devices (such as mobile phones, tablet computers, notebook computers or MPS players, etc.) to talk anytime and anywhere without being disturbed or affecting others. Functions such as listening to music have been widely used in daily life. [0003] In daily life, users are often disturbed by environmental noise such as the noise of air conditioners, cars, and locomotives, and the noise of crowds, and cannot easily and quietly use earphones to listen to clear sounds. In order to improve the playback quality and product efficiency of headphones, the industry has launched Active Noise Cancellation Headphone (ANC Headphone), which can suppress the ...
