Description

Technical Field

[0001] The utility model relates to the technical field of earphones, and specifically relates to an earphone with adjustable air permeability. Background Art

[0002] With the continuous development and popularization of audio technology, due to its excellent sound quality performance and noise reduction function, the over-ear headphones have become the first choice audio device for consumers in work, study, entertainment and sports. However, despite the significant progress made by over-ear headphones in audio experience, the airtight design of their earcup cavities has exposed a series of problems during actual use, especially having a non-negligible impact on user health and comfort experience.

[0003] For the existing over-ear headphones on the market, in order to achieve good sound insulation effect and immersive auditory experience, they often adopt an earcup cavity design with strong airtightness. Although this design effectively isolates external noise, it also leads to poor air circulation inside the earcups. After long-term wearing, the user's ears and ear canals are prone to discomfort due to stuffiness and dampness, and even cause health problems such as sweating in the ear canals, inflammation and allergic itching. Especially for users with a sweaty constitution or sensitive skin, these problems are particularly prominent, seriously affecting their use experience and physical health.

[0004] Specifically, the airtight and non-breathable earcup cavity design causes the temperature and humidity in the ear canals to rise rapidly during long-term wearing of the user, providing favorable conditions for the growth of microorganisms such as bacteria and fungi. The reproduction of these microorganisms not only causes ear canal inflammation, but may also cause allergic reactions, such as symptoms of ear canal itching and swelling. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides an earphone with adjustable air permeability, which solves the problems raised in the above background art.

[0007] An earphone body, with inner layer air holes reserved on both sides of the earphone body;

[0008] An annular object, with outer layer air windows provided on both sides of the annular object. The annular object and the earphone body can rotate relative to each other. After rotation, the inner layer air holes are communicated with the outer layer air windows, and after rotating back by the same amplitude, the inner layer air holes are not communicated with the outer layer air windows.

[0009] Furthermore, the earphone with adjustable air permeability further comprises:

[0010] A sealing ring, which is arranged inside the annular groove reserved on the edge of the earphone body;

[0013] Furthermore, a guide rod is connected to the end face of the earphone main body, a guide groove is reserved on the inner surface of the ring, and the guide rod moves along an arc path inside the guide groove.

[0014] Furthermore, an air permeability reference mark and an airtightness reference mark are respectively arranged on the edge of the earphone main body, an activity reference mark is arranged on the edge of the ring, after the ring rotates, the activity reference mark corresponds to the air permeability reference mark, and after the ring rotates back by the same amplitude, the activity reference mark corresponds to the airtightness reference mark.

[0015] Furthermore, the air permeability reference mark and the activity reference mark have the same shape and are in a strip structure, and the airtightness reference mark has a different shape from the air permeability reference mark and the activity reference mark and is in a dot structure.

[0016] Furthermore, a middle layer air hole is reserved inside the sealing ring, and the middle layer air hole is communicated with the inner layer air hole.

[0017] Furthermore, the sealing ring is made of silica gel material, and the earcup is made of PU soft leather material.

[0018] The utility model provides an earphone with adjustable air permeability. Compared with the prior art, it has the following beneficial effects:

[0019] For this earphone, by designing manually openable and closable air holes in the earphone, through a clever rotation structure design, the earcup can be rotated to realize the opening and closing of the air permeability. When the air hole is opened, free air convection is realized, so that the wearing and use have a good air permeability effect, solving the problem of stuffiness and sweating, and allowing the user to listen to external sounds. It is a good choice for running, playing games or listening to medium and high-frequency music, and is suitable for summer use. When the air hole is closed, the earcup is rotated to close the air hole, which can isolate external noise and better listen to low-frequency music, and is also suitable for winter warmth use.

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] Please refer to Figure 1-7 , the present utility model provides a technical solution: An adjustable air permeability earphone mainly consists of an earphone main body 1, a sealing ring 2, an annular object 3 and an ear cup 4. Among them, the sealing ring 2 is made of silica gel material and plays a role in waterproofing and dustproofing. The ear cup 4 is made of PU soft leather material, which will be more comfortable to wear. Specifically, in the assembly process, the sealing ring 2 is fixed in the annular groove 11 reserved at the edge of the earphone main body 1. And in order to further fix the sealing ring 2, several clamping holes 22 are reserved on the sealing ring 2 itself, and convex columns 13 that can be engaged and fixed with the clamping holes 22 are also provided inside the annular groove 11, so as to restrict the position of the sealing ring 2. The annular object 3 is rotatably connected to the end of the earphone main body 1. In order to cooperate with the rotation of the annular object 3, a guide rod 14 is connected to the end of the earphone main body 1, and a guide groove 33 is provided on the inner surface of the annular object 3. In order to accommodate the rotation of the annular object 3, the guide groove 33 has the same radian as the annular object 3. In this way, when the annular object 3 rotates, after being restricted by the guide rod 14 and the guide groove 33, the rotation amplitude will be limited;

[0030] In addition, inner air holes 12 are reserved on both sides of the earphone body 1, and middle air holes 21 are reserved inside the sealing ring 2. The inner air holes 12 and the middle air holes 21 are always kept connected. Outer air windows 31 are set on both sides of the annulus 3. When the annulus 3 and the earphone body 1 rotate relative to each other clockwise and rotate until they cannot rotate (that is, the guide rod 14 is engaged with the bottom end of the guide groove 33), the outer air windows 31, the middle air holes 21 and the inner air holes 12 are connected at this time. The external air flow can pass through the outer air windows 31, the middle air holes 21 and the inner air holes 12 in turn and enter the wrapped range of the earmuffs 4. That is to say, free air convection is achieved, so that the wearer has a good ventilation effect and solves the problem of stuffiness and sweating. You can listen to external sounds, which is a good choice for running / interactive gaming / listening to mid- and high-frequency music, and is suitable for use in summer. Similarly, when the annular object 3 and the earphone body 1 rotate counterclockwise relative to each other, and rotate until they cannot rotate (that is, the guide rod 14 is engaged with the top of the guide groove 33), the outer air window 31 is staggered with the middle air hole 21 and the inner air hole 12, and the channel is closed, and the outside air cannot enter the wrapped range of the earmuff 4. In other words, rotating the earmuff to close the air vent can isolate external noise and better listen to low-frequency music. At the same time, it is suitable for keeping warm in winter.

[0031] Finally, in order to facilitate knowing whether the earphone is in a breathable state at this time, a breathable position reference mark 15 and a closed position reference mark 16 are respectively set on the edge of the earphone body 1, and a movable reference mark 32 is set on the edge of the ring 3. After the ring 3 is rotated, the movable reference mark 32 corresponds to the breathable position reference mark 15. After the ring 3 rotates the same amplitude, the movable reference mark 32 corresponds to the closed position reference mark 16. The breathable position reference mark 15 and the movable reference mark 32 have the same shape and are a strip-like structure. The closed position reference mark 16 is different from the breathable position reference mark 15 and the movable reference mark 32 in shape and is a dot-like structure. The different shapes will be more eye-catching when the user identifies and observes, so that the user can see it at a glance.
