The first sound-absorbing pad 14 is embedded in the second cavity 124, the receiver 15 is provided in the first cavity 123, and the second sound-absorbing pad 16 is covered on the inner shell 122.

[0036] The earphones proposed in the present invention provide primary isolation of external noise through the outer shell 121 and the first sound-absorbing pad 14 placed between the second cavity 124, and secondary isolation of external noise through the inner shell 122 and the second sound-absorbing pad 16 covering the inner shell 122. With the graded isolation of external noise by the ear shell 10, the user's in-ear noise is reduced, and there is no need to increase the volume of the earphones to clearly hear the content played by the earphones, thus avoiding the user being in a high-volume environment for a long time, thereby reducing hearing damage caused by the high volume to the user.

[0037] In this embodiment, a stem 17 is connected to one of the ear shells 10. The stem 17 includes a stem body 17, a rotating shaft 172 rotatably connected to the stem body 17, and a bolted connection to the ear shell 10.

The adapter 173 is provided with a plurality of hemispherical bosses 173a, and the rotating piece 174 is provided with a plurality of grooves 174a that mate with the bosses 173a. When the stem body 17 rotates, the adapter 173 rotates about the rotating shaft 172 and relative to the rotating piece 174. In specific implementation, the speech rod 17 is fixed to the ear shell 10 by means of bolts. In this embodiment, rubber sheets are provided on the inner side of the rotating shaft 172 and the ear shell 10, and on the outer side of the rotating shaft 172 and the ear shell 10. It can be understood that the rubber sheet is conducive to a more stable connection between the speech rod 17 and the ear shell 10; a hemispherical boss 173a is provided on the adapter 173, and a groove 174a adapted to the boss 173a is provided on the rotating plate 174. When the speech rod 17 rotates, the adapter 173 rotates relative to the rotating plate. The hemispherical boss 173a is conducive to improving the damping feeling during rotation, thereby further improving the user experience.

[0038] In this embodiment, the base plate 13 includes a first snap-fit portion 131 located at an edge of the base plate 13 and a second snap-fit portion 132 located in the middle of the base plate 13. The first snap-fit portion 131 snaps into the outer shell 121, and the second snap-fit portion 132 snaps into the inner shell 122. The first snap-fit portion 131 and the second snap-fit portion 132 snap into the outer shell 121 and the inner shell 122, respectively, improve the seal between the base plate 13 and the concha 10, preventing external sound from entering through the gap between the base plate 13 and the concha 10, thereby further enhancing the noise reduction effect of the earphone.

[0039] In this embodiment, the headband 11 includes two groups of connecting rods 111 and a headband body 112 respectively connected to the two groups of connecting rods 111. The connecting rods 111 are connected to a connecting bracket 113 at one end away from the headband body 112. The connecting bracket 113 is fixed to the concha 10 by snapping. The connecting bracket 113 includes a first connecting plate 114 and a second connecting plate 115 extending outwardly perpendicular to the first connecting plate 114. The first connecting plate 114 is provided with an elliptical first fixing hole 116. The edge of the first connecting plate 114 is provided with a notch 117 that communicates with the first fixing hole 116. A fixing platform 101 is fixed to the concha 10. The fixing platform 101 is recessed inward to form an elliptical first limiting portion 102. The first limiting portion 102 is embedded in the first fixing hole 116. During specific implementation, first align the notch 117 on the first connecting plate 114 with the upper end of the elliptical first limiting portion 102, and insert it onto the first limiting portion 102. After the first limiting portion 102 is completely embedded in the first fixing hole 116, rotate the connecting bracket 113 90°. At this time, the connecting bracket 113 is fixed to the fixing platform 101 on the ear shell 10. This design has a simple structure and is easy to disassemble. When the ear shell 10 or the headband 11 is damaged, it is convenient to replace and disassemble for repair.

[0040] In this embodiment, a second fixing hole 118 is formed in the second connecting plate 115, and two second limiting portions 119 are provided on the inner wall of the second fixing hole 118 in an opposite direction. The connecting rod 111 is provided with positioning platforms 1111 spaced apart from each other. The positioning platforms 1111 are formed on the left and right sides of the connecting rod 111. In practice, the connecting rod 111 can be inserted into the second fixing hole 118. When the second limiting portions 119 in the second fixing hole 118 are located between the two positioning platforms 1111 spaced apart from each other on the connecting rod 111, the connecting rod 111 can be rotated 90 degrees so that the upper and lower positioning platforms 1111 on the connecting rod 111 abut against the second limiting portions 119 on the inner wall of the second fixing hole 118, thereby limiting the upward and downward movement of the connecting rod 111, thereby achieving a fixed connection between the connecting rod 111 and the connecting bracket 113. This design is simple in structure and easy to disassemble. When the connecting rod 111 or the connecting bracket 113 is damaged, it is convenient to replace and disassemble it for maintenance.

[0041] In this embodiment, two positioning posts 18 extend outward from the bottom of the inner housing 122. These posts 18 are provided with positioning holes (not shown). A fixing plate 19 extends outward from each end of the receiver 15. These fixing plates 19 are provided with mounting holes (not shown) for securing the receiver 15 to the positioning posts 18. In practice, the receiver 15 and the positioning posts 18 are connected by bolts, facilitating replacement and repair of the receiver 15 in the event of damage.

[0042] In this embodiment, the ear shell 10 further includes an ear pad 20 disposed on the base plate 13 at an end away from the housing 12. It is understood that providing the ear pad 20 on the base plate 13 can not only improve the comfort of the earphone, but also further block external noise, thereby improving the noise reduction effect of the earphone.

[0043] In this embodiment, the connecting rod 111 is integrally formed with the headband body 112. In a specific implementation, the connecting rod 111 and the headband 11 are integrally formed by an injection molding process. It can be understood that the integral molding of the connecting rod 111 and the headband 11 is conducive to increasing the structural strength of the headband 11.

[0044] In summary, the earphones in the above embodiments of the present invention perform primary blocking of external noise through the outer shell 121 and the first sound-absorbing pad 14 placed between the second cavity 124, and perform secondary blocking of external noise through the inner shell 122 and the second sound-absorbing pad 16 covering the inner shell 122. Under the action of the ear shell 10 to block external noise in a graded manner, the noise entering the user's ear is reduced, and the damage to the user's hearing caused by external noise is reduced. There is no need to increase the volume of the earphones to hear the content played by the earphones clearly, which avoids the user being in a high-volume environment for a long time, thereby reducing the hearing damage caused by the high volume to the user. This solves the problem in the prior art that the noise reduction effect of the earphones is poor, and the user needs to be in a high-volume environment to receive the content played in the earphones, which easily causes hearing damage to the user.

[0045] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
