The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0029] See also Figures 1 to 3 The first embodiment of the present invention provides an earphone assembly 100, comprising discretely distributed assembly parts 11 and a connecting plate 10 arranged between adjacent assembly parts 11, wherein the number of the assembly parts 11 is three, and the connecting plate 10 adopts an "L"-shaped structure, and the two ends of the connecting plate 10 are respectively connected to the outer walls of the adjacent assembly parts 11. In this embodiment, the assembly part 11 is arranged between the earphone shell and the printed circuit board, and the assembly part 11 is used to adopt a resistance limiting method to improve the stability of the structure between the earphone shell and the printed circuit board, and the connecting plate 10 is used to play a load-bearing connection role between adjacent assembly parts 11.

[0030] Specifically, in this embodiment, the assembly part 11 includes a support plate 13 arranged between the earphone shell and the printed circuit board and an elastic arm 12 arranged on the support plate 13, wherein the support plate 13 includes a first bearing plate 111 and a second bearing plate 112 bent and fitted with the first bearing plate 111, the first bearing plate 111 is connected to the connecting plate 10, and the elastic arm 12 includes a first limiting arm 14 and a second limiting arm 15 respectively arranged on the outside of the first bearing plate 111 and the second bearing plate 112, the first limiting arm 14 and the second limiting arm 15 respectively conflict with the earphone shell and the printed circuit board, in this embodiment, the three elastic arms 12 are not in the same vertical plane, so that the earphone assembly 100 described in this embodiment adopts a three-section connected body to limit the conflict between the earphone shell and the printed circuit board, and the three-section connected body can effectively waterproof the gap in the assembly process of the earphone shell.

[0031] Specifically, the first limiting arm 14 includes a first extension plate 141 connected to the first supporting plate 111 and a first limiting plate 142 bent and connected to the first extension plate 141, and the second limiting arm 15 includes a bending plate 151 connected to the second supporting plate 112, a second extension plate 152 connected to the bending plate 151, and a second limiting plate 153 bent and connected to the second extension plate 152, wherein the bending plate 151 adopts a semicircular structure. Through the design of the bending plate 151, the connection and fixation between the second supporting plate 112 and the second extension plate 152 are carried out in a circular arc transition connection manner, thereby ensuring the elasticity between the second supporting plate 112 and the second extension plate 152, preventing damage to the second limiting arm 15, and improving the service life of the elastic arm 12.

[0032] Preferably, in this embodiment, the first extension plate 141 and the second extension plate 152 are respectively used to increase the extension height of the first limiting plate 142 and the second limiting plate 153, so as to reduce the interference distance between the first limiting plate 142 and the earphone shell, and between the second limiting plate 153 and the printed circuit board, thereby improving the assembly effect between the earphone shell and the printed circuit board.

[0033] Furthermore, avoidance holes are provided on the first supporting plate 111 and the second supporting plate 112, and the avoidance holes are used to facilitate the connection and fixation between the first extension plate 141 and the first supporting plate 111. The first extension plate 141 is connected to the inner wall of the avoidance hole and extends back to the first supporting plate 111. The second limiting arm 15 is arranged at the rear end of the first limiting arm 14, and the extension height of the second limiting arm 15 is greater than the extension height of the first limiting arm 14.

[0034] In addition, in this embodiment, the first bearing plate 111, the connecting plate 10, the second extension plate 152 and the second limiting plate 153 are made of an integrally formed structure, thereby ensuring the height difference between the first bearing plate 111, the connecting plate 10, the second extension plate 152 and the second limiting plate 153, and preventing elastic deformation caused by inconsistent height difference. Preferably, both the first extension plate 141 and the second extension plate 152 are provided with assembly holes, and the assembly holes adopt a circular through-hole structure, and the hole surface of the assembly holes is parallel to the horizontal plane of the first extension plate 141 or the second extension plate 152, respectively, and the first limiting plate 142 and the second limiting plate 153 are both made of elastic plates, and the elastic coefficient of the first limiting plate 142 is greater than the elastic coefficient of the second limiting plate 153.

[0035] Furthermore, the connecting plate 10 and the supporting plate 13 are both wrapped in plastic and arranged in the earphone shell, the first limiting arm 14 is arranged between the outer shell and the inner shell of the earphone shell, the second limiting arm 15 penetrates the inner shell and extends out of the earphone shell, and contacts with the printed circuit board. Since there is a gap during the assembly process of the inner shell and the outer shell of the earphone shell, in this embodiment, through the design of the first limiting arm 14 and the second limiting arm 15, the gap between the inner shell and the outer shell can be effectively blocked, thereby improving the waterproof and sweat-proof effect of the earphone shell.

[0036] The assembly hole can also adopt a groove-shaped structure, and the assembly hole is arranged at one end facing away from the connecting plate 10. The assembly hole is used for positioning and assembling the earphone assembly 100 and the assembly column in the earphone shell, and effectively reduces the position movement or falling-off phenomenon caused by the structural vibration between the earphone assembly 100 and the earphone shell. Preferably, the connecting plate 10 and the support plate 13 are provided with a plurality of reinforcing ribs. Through the design of the reinforcing ribs, the structural strength of the connecting plate 10 and the support plate 13 is effectively guaranteed. Furthermore, the connecting plate 10 and the support plate 13 are provided with a plurality of avoidance grooves, and the avoidance grooves adopt a semicircular groove structure and are sequentially and parallelly arranged on the connecting plate 10 and the support plate 13. The avoidance grooves are used for avoiding sound transmission in the sound cavity of the earphone shell, thereby effectively ensuring the sound effect of the earphone.

[0037] In this embodiment, the first limiting arm 14 and the second limiting arm 15 are designed to respectively interfere with the earphone housing and the printed circuit board, thereby effectively achieving a two-way limiting effect between the earphone housing and the printed circuit board, thereby improving the stability of the overall assembly structure of the earphone.

[0038] See also Figure 4 , is a structural schematic diagram of an earphone assembly 100 provided in a second embodiment of the present invention.

Preferably, a snap member is provided in the middle of the snap plate 17, and the snap member is made of a buckle, a groove or a hole-shaped structure. In the present embodiment, the snap member is used for snap assembly between the connecting plate 10 and the earphone shell, thereby further ensuring the stability of the structure between the connecting plate 10 and the earphone shell. Furthermore, arc grooves are provided on both sides of the snap plate 17, and the arc grooves are used for avoidance between the snap plate 17 and the assembly 11 in the earphone shell, thereby preventing the earphone assembly 100 from interfering with the assembly of the printed circuit board in the earphone shell.

[0040] Preferably, in the present embodiment, a waterproof seat 104 is provided between the printed circuit board and the earphone assembly 100, the waterproof seat 104 adopts a "concave" structure, the concave opening of the waterproof seat 104 faces away from the earphone assembly 100, a gap hole is provided at the bottom of the waterproof seat 104, and the second elastic arm 12 abuts against the gap hole, thereby further preventing rainwater or sweat from penetrating into the interior of the waterproof earphone 101, thereby improving the waterproof performance of the waterproof earphone 101 and improving the user experience.
