[0001] The utility model relates to the technical field of wired earphone design, in particular to an in-ear wired earphone. Background Art

[0002] An in-ear wired earphone is a wired earphone. Its characteristic is that when in use, the sound outlet nozzle of the earphone needs to be inserted into the ear canal of the user. In order to improve the comfort of use, at present, many in-ear wired earphones are provided with elastic ear tips, such as common silicone ear tips. The ear tips are located at the sound outlet nozzle and extend into the ear canal of the user and contact the inner wall of the ear canal when in use. Moreover, by replacing different ear tips, the sound effect can also be adjusted.

[0003] In traditional in-ear wired earphones, since the ear tips are elastic, usually the tail end of the ear tip is sleeved outside the sound outlet nozzle of the earphone. The disadvantage of this design is that during actual use, the ear tips are likely to become loose due to pulling or friction, especially during the carrying process, and the problem of ear tip loss often occurs. Summary of the Utility Model

[0004] Based on this, the utility model provides an in-ear wired earphone, which uses a locking sleeve that rotates by threads to lock the ear tip at the outer end of the sound outlet nozzle in a biting manner, so that the ear tip is not easily loosened due to pulling or friction, and reduces the risk of ear tip loss during the carrying process.

[0039] As Figures 1 to 11 shown, it is an in-ear wired earphone 100 of an embodiment of the present utility model.

[0040] As Figure 1 shown, the in-ear wired earphone 100 includes: a data line 10, and a first playback component 20 and a second playback component 30 respectively connected to the data line 10. Among them, the data line 10 is used to connect to a sound source (for example, a mobile phone, a desktop computer, a tablet computer, etc.) and transmit an audio signal to the first playback component 20 and the second playback component 30. The first playback component 20 and the second playback component 30 are used to be inserted into the ear canal and convert the audio signal into sound for playback.

[0041] Below, in combination with Figures 1 to 11 , the above in-ear wired earphone 100 will be further described.

[0042] As Figure 2As shown, in this embodiment, the data line 10 is in a Y shape. One end of the data line 10 is provided with a first metal connector 11, and the other end of the data line 10 is provided with a first branch line 12 and a second branch line 13. Among them, the first metal connector 11 is used to connect to the sound source, the first branch line 12 is used to connect to the first playback component 20, and the second branch line 13 is used to connect to the second playback component 30.

[0043] Combined with Figures 2 to 5 As shown, the first playback component 20 includes: a first earphone 21 connected to the first branch line 12, a first earplug 22 sleeved on the first earphone 21, and a first locking sleeve 23 sleeved between the first earphone 21 and the first earplug 22. As Figure 6 As shown, the inner end of the sound outlet nozzle of the first earphone 21 is provided with a first external thread 211. As Figure 3 And Figure 5 As shown, the tail end of the first earplug 22 is sleeved on the outer end of the sound outlet nozzle of the first earphone 21. As Figure 3 、 Figure 5 、 Figure 7 、 Figure 8 、and Figure 9 As shown, one end of the first locking sleeve 23 is sleeved on the inner end of the sound outlet nozzle of the first earphone 21 and is provided with a first internal thread 231 that meshes with the first external thread 211. The other end of the first locking sleeve 23 is provided with a first snap ring 232 that bites the tail end of the first earplug 22, and the aperture of the first snap ring 232 gradually decreases from the inside to the outside.

[0044] In this embodiment, the first playback component 20 and the second playback component 30 are arranged in a symmetric structure. Therefore, for the structural schematic diagram of the second playback component 30, reference can be made to the first playback component 20. As Figure 2 As shown, the second playback component 30 includes: a second earphone 31 connected to the second branch line 13, a second earplug 32 sleeved on the second earphone 31, and a second locking sleeve 33 sleeved between the second earphone 31 and the second earplug 32. The inner end of the sound outlet nozzle of the second earphone 31 is provided with a second external thread. The tail end of the second earplug 32 is sleeved on the outer end of the sound outlet nozzle of the second earphone 31. One end of the second locking sleeve 33 is sleeved on the inner end of the sound outlet nozzle of the second earphone 31 and is provided with a second internal thread (not shown in the figure) that meshes with the second external thread. The other end of the second locking sleeve 33 is provided with a second snap ring (not shown in the figure) that bites the tail end of the second earplug 32. The aperture of the second snap ring gradually decreases from the inside to the outside.

[0045] In order to improve the smoothness when the locking sleeve is docked with the earplug, as Figure 11 As shown, in this embodiment, the tail ends of both the first earplug 22 and the second earplug 32 are provided with rounded corners. The rounded corners enable the snap ring of the locking sleeve and the tail end of the earplug to complete the docking smoothly when they come into contact, reducing the sense of blockage during docking.

[0046] Considering the in-ear design, during use, debris in the ear canal may invade the earphone from the sound outlet nozzle. Therefore, as Figure 6 shown, in this embodiment, a first mesh 24 is provided at the entrance of the sound outlet nozzle of the first earphone 21. A second mesh (not shown in the figure) is provided at the entrance of the sound outlet nozzle of the second earphone 31. The mesh can filter debris and reduce the risk of debris invading the interior of the earphone from the sound outlet nozzle.

[0047] To improve the accuracy of ear tip installation, the following improvements can also be made.

[0048] For example, as Figure 5 and Figure 6 shown, in this embodiment, a first stop portion 212 that abuts against the tail end of the first ear tip 22 is provided at the outer end of the sound outlet nozzle of the first earphone 21. A second stop portion (not shown in the figure) that abuts against the tail end of the second ear tip 32 is provided at the outer end of the sound outlet nozzle of the second earphone 31. By restricting the depth of the ear tip at the sound outlet nozzle through the stop portion, it is beneficial to improve the assembly accuracy.

[0049] Also, for example, in other embodiments, a first card slot that matches the first snap ring 232 may be provided at the tail end of the first ear tip 22. A second card slot that matches the second snap ring may be provided at the tail end of the second ear tip 32. The card slot can be used as a marking line for the residence position of the snap ring and at the same time enhance the residence stability.

[0050] In addition, considering that during actual use, the data cable 10 is a relatively easily damaged part, for ease of maintenance, in some embodiments, a second metal plug that is detachably connected to the first earphone 21 is provided at the end of the first branch cable 12, and a third metal plug that is detachably connected to the second earphone 31 is provided at the end of the second branch cable 13. The detachable connection between the branch cable and the earphone can facilitate the replacement of parts and reduce the difficulty of maintenance.

[0051] To improve the wearing stability during use, some users may require ear hooks to be provided. Therefore, based on the above design of the detachable connection between the branch cable and the earphone, further, the in-ear wired earphone 100 may further include: a first ear hook and a second ear hook that respectively sleeve the data cable 10. Both the first ear hook and the second ear hook are arc-shaped sleeve structures. The first ear hook is sleeved on the first branch cable 12 and one end is clamped to the first earphone 21. The second ear hook is sleeved on the second branch cable 13 and one end is clamped to the second earphone 31. The detachable ear hook facilitates the user to choose whether to install the ear hook according to needs and improves the flexibility of use.

[0052] Considering that the in-ear design forms a seal in the ear canal, during use, it is easy to form high pressure in the ear canal due to the long-term closed environment, causing discomfort. Therefore, both the first earphone 21 and the second earphone 31 can be provided with pressure relief holes communicating with the sound outlet nozzle. The pressure relief holes can connect the sound outlet nozzle with the external environment, playing a role in relieving pressure and reducing the discomfort caused by the high pressure caused by the closed design of the in-ear type.

[0053] Brief description of the working principle:

[0054] During assembly, first rotate the locking sleeve towards the inner end of the sound outlet nozzle so that the locking sleeve stays at the innermost side of the sound outlet nozzle. Then, sleeved the tail end of the ear tip on the outer end of the sound outlet nozzle. Next, a user holds the earphone with one hand and presses against the ear tip to fix it at the outer end of the sound outlet nozzle, while the other hand rotates the locking sleeve towards the outer end of the sound outlet nozzle so that the snap ring bites the circumferential side of the tail end of the ear tip (the aperture of the inlet end of the snap ring is smaller than the outer diameter of the tail end of the ear tip, and based on the elastic characteristics of the ear tip, when the snap ring bites the ear tip, the inlet end of the snap ring will squeeze the ear tip towards the axis, and the ear tip deforms. Based on the design that the deformed area of the ear tip squeezed by the snap ring can enter the aperture of the snap ring where the aperture gradually decreases from the inside to the outside, the deformed part of the ear tip squeezed due to deformation can move towards the inside of the snap ring), thereby locking the ear tip at the tail end of the sound outlet nozzle.

[0055] The above in-ear wired earphone 100 uses a locking sleeve rotated by a thread to lock the ear tip at the outer end of the sound outlet nozzle in a biting manner, making it difficult for the ear tip to become loose due to pulling or friction, and reducing the risk of the ear tip being lost during carrying.

[0056] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0057] The above embodiments only represent the preferred implementation modes of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
