Description

Technical Field

[0001] This application relates to the field of headphones, and more particularly to a type of headphones. Background Technology

[0002] Existing headphones include a headband and earphone bodies mounted at both ends of the headband. The headband includes an outer shell, an inner shell, and a cap. The inner shell is mounted on the inner side of the outer shell and is used for cushioning foam. The inner shell has sliding parts at both ends. The cap is located at the end of the outer shell and forms a sliding cavity with the outer shell for the sliding parts to slide. During the process of manually straightening the headband, the outer shell and inner shell will deform, at which time the sliding parts can easily detach from the sliding cavity. Utility Model Content

[0003] To reduce the possibility of the sliding part disengaging from the sliding cavity, this application provides a headset.

[0004] This application provides a headset, which adopts the following technical solution:

[0005] A type of over-ear headphone includes an outer shell, an inner shell, and a cap. The outer shell and the inner shell are both arc-shaped and elastically arranged. Two caps are provided, each located at one end of the outer shell. The caps are engaged with the outer shell and form a sliding cavity with it. The inner shell has sliding portions at both ends. The length of the limiting portion is greater than the difference between the length of the outer shell and the length of the caps and the inner shell.

[0006] By adopting the above technical solution, the sliding part is slidably connected to the sliding cavity. When the outer shell and inner shell are deformed, since the length of the limiting part is greater than the difference between the length of the outer shell minus the length of the cap and the inner shell, the limiting part is not easy to detach from the sliding cavity, thereby improving the overall structural stability of the headphones.

[0007] Optionally, the outer shell is further provided with earphone bodies on both sides, and the earphone bodies are provided with connecting rods for connecting to the outer shell.

[0008] Optionally, the inner side of the housing is provided with a mounting plate, and the mounting plate is provided with a first sliding groove along the extension direction of the housing. The side of the connecting rod is provided with a first sliding block that is slidably connected to the first sliding groove.

[0009] By adopting the above technical solution, the headphone body is mounted on the connecting rod, and the connecting rod is slidably connected to the first sliding groove through the first sliding block, so that the position of the headphone body relative to the shell can be adjusted to suit different head sizes.

[0010] Optionally, the outer casing is provided with several sets of limiting blocks, which are distributed along the length direction of the connecting rod. Each set of limiting blocks includes two limiting blocks, which are located on both sides of the width direction of the connecting rod.

[0011] By adopting the above technical solution, several sets of limiting blocks are set up to further limit the connecting rod and improve the installation stability of the connecting rod.

[0012] Optionally, the limiting block has a second sliding groove on its side near the connecting rod, and the connecting rod has a second sliding block that is slidably connected to the second sliding groove on its side.

[0013] By adopting the above technical solution, a second sliding block is provided on the connecting rod, and the second sliding block is slidably connected to the second sliding groove on the two side limit blocks, thereby further improving the stability of the connecting rod's telescopic sliding.

[0014] Optionally, a boss is fixedly connected to the side of the limiting part away from the inner shell, and a third sliding groove is provided on the inner side of the cap along the extension direction of the outer shell, and the boss is slidably connected to the third sliding groove.

[0015] By adopting the above technical solution, a boss is provided on the limiting part, and the boss is slidably connected to the third sliding groove. The boss is limited by the third sliding groove, thereby reducing the possibility of the limiting part disengaging from the sliding cavity.

[0016] Optionally, a fourth sliding groove is provided on the side of the boss away from the sliding part, and a sliding piece is provided on the boss that is slidably connected to the fourth sliding groove. An elastic pad is provided between the side wall of the fourth sliding groove and the sliding piece.

[0017] By adopting the above technical solution, the inner shell and the limiting part will deform during the process of straightening the outer shell, which will affect the sliding of the boss. Therefore, a sliding piece is provided on the boss, and the sliding piece can adapt to changes during the deformation process.

[0018] Optionally, a steel ball is rotatably connected to the side of the sliding plate, and the steel ball abuts against the side wall of the third sliding groove.

[0019] By adopting the above technical solution, steel balls are set on the sliding plate, thereby reducing the sliding resistance between the sliding plate and the side wall of the third sliding groove.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. The sliding part is slidably connected to the sliding cavity. When the outer shell and inner shell deform, the limiting part is not easy to detach from the sliding cavity because the length of the limiting part is greater than the difference between the length of the outer shell minus the length of the cap and the inner shell, thereby improving the overall structural stability of the headphones.

[0022] 2. A boss is provided on the limiting part, and the boss is slidably connected to the third sliding groove. The boss is limited by the third sliding groove, thereby reducing the possibility of the limiting part disengaging from the sliding cavity. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0031] Example 1:

[0032] This application discloses an over-ear headphone. (Refer to...) Figure 1 and Figure 2 It includes an outer shell 1, an inner shell 2, and a cap 3. The outer shell 1 and the inner shell 2 are both arc-shaped and elastically set. There are two caps 3, which are respectively set at both ends of the outer shell 1. The caps 3 are snapped into the outer shell 1 and form a sliding cavity with the outer shell 1.

[0033] Reference Figure 1 and Figure 2 The inner shell 2 has sliding portions 21 at both ends, and the length of the limiting portion is greater than the difference between the length of the outer shell 1 minus the length of the cap 3 and the inner shell 2.

[0034] Reference Figure 3 and Figure 4 The outer shell 1 is provided with earphone bodies 4 on both sides. The earphone bodies 4 are fixedly connected to connecting rods 5. The connecting rods 5 are arc-shaped and adapted to the outer shell 1. The inner side of the outer shell 1 is fitted with a mounting plate 11.

[0036] The implementation principle of Embodiment 1 of this application is as follows: the sliding part 21 is slidably connected to the sliding cavity. When the outer shell 1 and the inner shell 2 are deformed, since the length of the limiting part is greater than the difference between the length of the outer shell 1 minus the length of the cap 3 and the inner shell 2, the limiting part is not easy to detach from the sliding cavity, thereby improving the overall structural stability of the headphones.

[0037] Example 2:

[0038] The difference between Example 2 and Example 1 is that, referring to Figure 5 and Figure 6 A boss 22 is fixedly connected to the side of the limiting part away from the inner shell 2, and the boss 22 is arranged around the limiting part. A third sliding groove 31 is opened on the inner side of the cap 3 along the extension direction of the outer shell 1, and the boss 22 is slidably connected to the third sliding groove 31.

[0039] Reference Figure 5 and Figure 6 The boss 22 has a fourth sliding groove 221 on the side away from the sliding part 21. The boss 22 is provided with a sliding piece 23 that is slidably connected to the fourth sliding groove 221. The boss 22 is provided with an elastic pad 24 located in the fourth sliding groove 221.
