Detailed ways

In order to describe the technical content, structural features, achieved goals and effects of the present utility model in detail, the following specific examples are given and described in detail with reference to the drawings.

Please refer to FIG. 1 , the earphone antenna 100 of the present invention is used together with an electronic product 9 having a display device 90 . In the embodiment of the present invention, the electronic product 9 is a mobile phone. In the first embodiment of the present invention, the earphone antenna 100 is composed of a plug 1 , a cable 2 and a speaker 3 . Please continue to refer to FIG. 2 , the plug 1 has a socket portion 10 and a connecting portion 11, the socket portion 10 is used for electrically connecting with the mobile phone 9 and transmitting the signal sent by the mobile phone 9 to the connecting portion 11, and connecting The signal sent by the connection part 11 is transmitted to the mobile phone 9 . The connecting portion 11 is used for electrically connecting with the cable 2 and transmitting the signal from the plugging portion 10 to the cable 2 , and transmitting the signal from the cable 2 to the plugging portion 10 .

The two ends of the cable 2 are respectively connected to the plug 1 and the speaker 3. The cable 2 includes at least one signal line 24, a first antenna 20, a second antenna 21, a matching antenna 22 and an insulating layer 23 for covering the signal. line 24 , the first antenna 20 , the second antenna 21 and the matching antenna 22 .
