Description

Technical Field

[0001] This utility model relates to the field of earplug technology, and more specifically, to a deformable in-ear mechanism and a noise-canceling earplug. Background Technology

[0002] In daily life, at work, or commuting, people often rely on acoustic devices to obtain a clear audio experience. However, noise interference in the external environment (such as traffic noise, machinery operating noise, noisy crowds, etc.) may affect call quality, music playback effect, and even cause auditory fatigue, reducing the user experience.

[0003] To improve audio quality and reduce the impact of environmental noise, various acoustic devices are widely used, such as headphones, earplugs, bone conduction devices, and hearing aids. However, existing methods of securing acoustic devices are prone to instability, leading to loosening during wear. Therefore, optimizing the wearing stability of acoustic devices has become an important direction for technological improvement. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing acoustic device fixing method is prone to instability, which leads to loose wearing. Therefore, how to optimize the wearing stability of the acoustic device has become an important direction for technical improvement. In view of the above-mentioned defects of the prior art, a deformable in-ear mechanism and noise-canceling earplug are provided.

In use, the wearing shell is clamped at the tragus, and the end of the wearing shell with the cover plate is in contact with the tragus. Air in the pressure-reducing cavity can be discharged through the gap between the noise-reducing component and the inner wall of the groove, as well as between the groove and the cover plate, to reduce the pressure exerted by the wearing shell on the tragus.

[0009] Optionally, the wearing body is made of flexible material, and the connection between the top, bottom and sidewalls of the ear-attaching part is rounded.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

[0037] Examples of embodiments of this utility model Figures 1-6 The diagram illustrates a deformable in-ear mechanism, including a wearing component. The wearing component includes a wearing body 100, which includes an ear-fitting portion 110 that contacts the auricle. A support portion 120, with a thickness less than the ear-fitting portion 110, is integrally formed in the middle of the ear-fitting portion 110. Furthermore, since the ear-fitting portion 110 is used to form a clip connection with the auricle, the earplug's stability is enhanced through a flexible clamping action during wear, preventing the earplug from loosening or falling out due to movement or external impact. To improve structural strength and wearing comfort, the support portion 120, with a thickness less than the ear-fitting portion 110, is integrally formed in the middle of the ear-fitting portion 110. This support portion 120 provides necessary deformation adaptability while ensuring that the earphone does not affect wearing stability due to excessive deformation. The acoustic device is an earphone or an earplug; in this embodiment, the acoustic device is an earplug, and the wearing component body is used to connect to the acoustic device.

[0038] Furthermore, a wearing shell 400 is provided on one side of the wearing body 100. A pressure-reducing cavity 410 is provided inside the wearing shell 400. One end of the pressure-reducing cavity 410 is connected to a groove 430, which penetrates the outer wall of the wearing shell 400. A noise-reducing component 440 is provided inside the groove 430. A cover plate 420 is provided at the opening of the groove 430. In use, the wearing shell 400 is clipped onto the tragus, and the end of the wearing shell 400 with the cover plate 420 contacts the tragus. Air in the pressure-reducing cavity 410 can pass through the noise-reducing component. The gaps between 440 and the inner wall of the groove 430, and between the groove 430 and the cover plate 420, are drained to reduce the pressure of the wearing shell 400 on the antitragus. This buffers the pressure of the wearing shell on the antitragus during wearing, avoiding discomfort to the antitragus and effectively improving wearing comfort. It is especially suitable for long-term wearing scenarios. The noise reduction component 440 is part of the earplug and can provide noise reduction for the user. It will not be elaborated on here. The antitragus is a cartilaginous tissue that protrudes upward below the auricle and near the opening of the external auditory canal. It is located on the opposite side of the "tragus". The crus of the helix is ​​the part of the helix that extends into the ear canal.

[0039] Furthermore, to reduce the pressure on the auricle contact area, the top, bottom and sidewall of the ear-attaching part 110 are rounded to make the edge transition smoother and avoid discomfort to the soft tissue of the ear caused by the sharp edges.

[0040] See Figures 1-6 In this embodiment, the wearing body 100 is made of a flexible material. Furthermore, the flexible material can be a material with the same or similar properties, such as silicone or thermoplastic polyurethane. Its properties include high elasticity, strong tear resistance, and resistance to deformation over long-term use. It also has good skin contact adaptability. Through the properties of the flexible material, the wearing body 100 can undergo a certain deformation when clipped to the auricle, so that it can adapt to different users' ear shapes and improve the universality of wearing.

[0041] To ensure that the wearing body 100 maintains sufficient structural strength while undergoing flexible deformation, the support part 120 is formed with a plurality of reinforcing ribs 200 connected to the inner side of the ear-attaching part 110. The reinforcing ribs 200 are distributed along the inner side of the support part 120, so that the wearing body 100 has better structural stability under stress, while avoiding excessive deformation that could cause the earplug to loosen or lose support.

[0042] See Figures 1-6In this embodiment, the ear-mounted portion 110 is arc-shaped and formed along the ear canal fitting path to adapt to the ear shape of different users, so that the earphone has better fit and support during wearing. Preferably, the bending angle of the ear-mounted portion 110 is 90 degrees to 170 degrees, so that the wearing body 100 provides a cushioning effect when attached to the ear canal, avoiding excessive local pressure that affects comfort. Specifically, the bending angle of the ear-mounted portion 110 is any one of 110 degrees, 130 degrees, and 150 degrees.

[0043] In this embodiment, the cross-section of the ear-mounted portion 110 is a gradually curved surface structure, and its thickness gradually decreases from the outside to the inside, so as to further optimize the fit of the earphone, improve the wearing comfort, and reduce local pressure on the auricle.

[0044] See Figures 1-6 In this embodiment, a transition portion 300 is provided between the ear-fitting portion 110 and the support portion 120. The thickness of the transition portion 300 is smaller than that of the ear-fitting portion 110 and larger than that of the support portion 120, which helps to smoothly transition the stiffness difference between the ear-fitting portion 110 and the support portion 120, so that the earphone has appropriate support during wearing without affecting its flexible adaptability.

[0045] See Figures 1-6 The wearable body 100 has a relief opening on its side wall for avoiding the helix foot. The helix foot is a relatively protruding part of the auricle. If the wearer is close to or presses on this part, it is easy to cause discomfort or pain. By setting the relief opening, this part is not pressed when wearing, thereby reducing the feeling of pinching the ear and improving the comfort of wearing for a long time.

[0046] See Figures 1-6 A noise-canceling earplug includes a deformable in-ear mechanism and an ear cap 500. The ear cap 500 is located at the end of the wearing shell 400 away from the wearing body, and adopts an ear-fitting part 110 to adapt to different users' ear shapes, achieving a stable fit and preventing the earplug from loosening or falling out. The wearing body 100 and the wearing shell 400 cooperate with the tragus and antihelix to clamp, providing good stability and preventing the earplug from shifting or falling out during strenuous exercise or prolonged wear. The ear cap 500 is a component that is directly inserted into the ear canal, which can buffer pressure in the ear canal, avoiding direct compression of the earplug into the ear canal and reducing wearing fatigue.
