In view of the above problems, embodiments of the present application provide the following technical solutions to overcome the above problems.

Referring to fig. 1, fig. 2 and fig. 3, the present embodiment provides an anti-static structure for an earphone, including an earphone body 110 and a metal shaft sleeve 120 connected to the earphone body 110, wherein a circuit board 130 is disposed in the earphone body 110, a ground wire interface 132 is disposed on the circuit board 130, and the metal shaft sleeve 120 is connected to the ground wire interface 132 through a conductor 140.

Specifically, by connecting the metal sleeve 120 with the ground interface 132, when the bluetooth headset is used, static electricity on a human body can be conducted onto the metal sleeve 120, the metal sleeve 120 is conducted to the ground interface 132 through the conductive body 140, and the ground interface 132 can be regarded as a negative electrode of a circuit, and since current always flows in a low impedance direction, when the static electricity is conducted into the ground interface 132, the static electricity is also conducted into the negative electrode of the circuit, and the static electricity cannot enter the integrated circuit of the circuit board 130 to affect the normal operation of the bluetooth headset.

The antistatic structure of earphone that this application embodiment provided, through earphone body 110 to and the metal shaft sleeve 120 of being connected with earphone body 110, can play the effect of stable support through metal shaft sleeve 120 to earphone body 110. Meanwhile, the metal shaft sleeve 120 is connected with the ground wire interface 132 of the circuit board 130 arranged in the earphone body 110 through the conductive body 140, so that static electricity at the metal shaft sleeve 120 can be conducted to the ground wire interface 132 in time to eliminate the static electricity in time, and damage to other components arranged on the circuit board 130 during static electricity discharge is avoided. By adopting the mode, static electricity generated in use can be eliminated, and the stability in use is improved.

As shown in fig. 4 and 5, the earphone body 110 includes a first housing 112 and a second housing 114 that are fastened to each other, a positioning hole 1122 is formed on the first housing 112, an ear plate 122 is formed on the metal sleeve 120, and a connecting hole 1222 is formed on the ear plate 122, so that a fastening member 124 sequentially passes through the connecting hole 1222 and the positioning hole 1122 to connect the first housing 112 and the metal sleeve 120.

Specifically, when the earphone body 110 is connected to the metal sleeve 120 in a matching manner, the positioning hole 1122 of the first housing 112 corresponds to the connecting hole 1222 of the ear plate 122, so that the fastening member 124 sequentially passes through the connecting hole 1222 and the positioning hole 1122 to achieve the desired connection relationship. The fastening member 124 may be a screw or a lock, as long as the stability and reliability of the connection are ensured.

Referring to fig. 3 and fig. 4, a protrusion 1142 is disposed on the second casing 114, and a fastening groove 126 corresponding to the protrusion 1142 is disposed on the metal shaft sleeve 120, so that the protrusion 1142 is fastened with the fastening groove 126.

Thus, when earphone body 110 and metal sleeve 120 cooperate, arch 1142 on second casing 114 can also with joint groove 126 joint to carry on spacingly to second casing 114, be favorable to guaranteeing the stability of connecting, avoid the skew that takes place the position in the use.

When the conductive body 140 is connected to the ground interface 132, it may be in the form of welding, and may be in the form of screw fastening. Similarly, when the conductive body 140 is connected to the metal bushing 120, the conductive body 140 may be held between the fastening member 124 and the lug plate 122 to be connected to the metal bushing 120, or may be directly welded to the metal bushing 120, as long as a stable connection can be ensured.

As shown in fig. 2 and 3, a sound guide 150 for accommodating the sound emitting unit is disposed between the first casing 112 and the second casing 114, and the sound guide 150 isolates the fastening member 124 from the circuit board 130.

For example, the sound guide 150 may be formed by injection molding, and the fastening member 124 may be conveniently isolated from the circuit board 130 by using the sound guide 150 made of plastic. Wherein, the sound guide member 150 is provided with an abdicating notch to facilitate the matching connection of the fastening member 124 and the ear plate 122. With the above configuration, while the sound guide 150 conducts the sound generated by the sound generating unit, the circuit board 130 can be protected, and the placement of the fastening member 124 or the conductive member 140 affects the circuit board 130.
