Description of the Invention: [Technical Field] The present invention relates to a headphone puller A, and more particularly to a headphone puller A having electrostatic discharge protection. [Prior Art] Referring to Fig. 1, a headphone bar π is generally used to prevent foreign matter from entering the speaker 41, and a metal mesh cover 42 is usually used to cover the periphery of the speaker 41 to protect the speaker 41 from foreign matter, but the metal mesh cover 42 It is easy to accumulate static electricity and generate an electrostatic effect. The electrostatic effect not only absorbs floating dust or particles that are diffused in the air outside the metal mesh cover 42 but also affects the earphones. The quality of the eight, even if the body and the headphone speaker have a potential difference, then the human body, such as the contact lens, will cause a surge in the discharge of the earphone, which is called Electrostatic Discharge (ESD). Electrostatic discharge is the main factor that causes most electronic components or electronic systems to be damaged by excessive electrical stress (Electrkai 〇verstress, EOS). This kind of damage will make the speaker and audio amplifier in the headset team work abnormally. It even led to an increase in the damage rate of the headset. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide an earphone A having electrostatic discharge protection, thereby avoiding electrostatic discharge damage and improving service life. Thus, the present invention has an electrostatic discharge protection earphone, and eight comprises a % acoustic unit, a metal mesh cover, and a flexible conductive member. The speaker unit includes an input terminal for receiving an audio signal, and a speaker port for outputting an audio signal, the input terminal having a positive contact and a negative contact. The metal 1269599 net cover covers the speaker member to protect the speaker port. The slidable conductive member has a second end that is fixed to the negative contact m-opposite the first end and abuts the metal mesh cover. The above and other technical contents, features, and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments. Referring to FIG. 2 and FIG. 3, a preferred embodiment of the earphone port 8 having electrostatic discharge protection is mounted in an earphone (not shown) and includes a speaker unit 1 and a metal mesh cover 2. And a flexible conductive member 3. In this embodiment, the singularity of the unilateral earphone is shown in the figure. However, those skilled in the art can easily understand it, and can also be used in the bilateral earphones. The speaker unit 1 includes a speaker unit corresponding to the ear of the human body, and a wire 12 electrically connected to the speaker 11 for transmitting an audio signal. The speaker 11 includes a body 111, an input end 112 at the rear end of the body ηι (ie, to the right of the figure) for receiving an audio signal, and a front end of the body ηι (ie, the left side of the figure) and used for A speaker port 113 for outputting an audio signal, wherein the input terminal 112 has a negative contact 114 and a positive contact 丨i 5 . In this embodiment, since the speaker U is a known and mature technology, it will not be described herein. In the present embodiment, the wire 12 is soldered to the input terminal 112, thereby securing and forming an electrical connection. The metal mesh cover 2 is disposed on the side of the speaker unit 1 and covers the front end of the speaker 11 to prevent foreign matter from entering, causing damage to the speaker unit 1269599. The metal mesh cover 2 has a plurality of sound holes 21 formed through the face inward for transmitting sound signals. θ柏, In the actual case, the flexible conductive member 3 may be a metal dome or a copper: sheet 31. The flexible conductive member 3 has - fixed to the negative contact m
