Description

Technical Field

[0001] This utility model relates to the field of headphone technology, and in particular to an open-back headphone. Background Technology

[0002] Over-ear headphones, as the name suggests, are a type of headphone worn on the head. These headphones typically consist of a headband and two earpieces; the earpieces are connected to the sides of the headband, and each earpiece contains acoustic components to transmit sound directly to the user's ears. The earcups of each earpiece are often filled with soft materials such as foam or memory foam to provide a comfortable wearing experience and help isolate external noise, enhancing the user's listening experience. Over-ear headphones, with their superior sound quality, excellent noise isolation, and diverse features, have become the first choice for many music lovers and gamers.

[0003] Because headphones have earcups on the earpiece, the area around the ears becomes stuffy and uncomfortable after prolonged use, especially in warmer temperatures. This significantly impacts the user experience. Additionally, prolonged wear can lead to sweat buildup, which further reduces the lifespan of the earcups.

[0004] Therefore, some open-back headphones have appeared on the market. Most of them have ventilation holes on the headphones to allow the ears to breathe and solve the problem of stuffiness. However, most of these open-back headphones expose the ears to the air after being worn, which makes it easy for outside wind to enter the headphones and affect the noise cancellation effect and ear insulation.

[0005] Therefore, for open-back headphones, how to solve the problems of wind noise and ear insulation in cold weather, and how to improve the noise cancellation effect of headphones in certain situations are all issues that urgently need to be addressed. Utility Model Content

Detailed Implementation

[0035] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0036] To facilitate understanding by those skilled in the art, the specific implementation process of the technical solutions in this application is illustrated through the following specific embodiments.

[0037] Example 1:

[0038] Please see Figure 1 This embodiment of an open-back headphone includes a headband 10 and two earpieces 20. The two earpieces 20 are respectively connected to both sides of the headband 10.

[0039] Please see Figure 2 - Figure 5As shown, at least one earphone body 20 includes an earphone shell 21, an acoustic component 22, and an earcup 23; the acoustic component 22 is disposed in the middle of the earphone shell 21, and the acoustic component 22 is connected to the earphone shell 21 by a connecting plate 211, and the connecting plate 211 has a first vent 201 communicating with the outside; the earcup 23 is detachably or movably disposed on the earphone shell 21, and the earcup 23 has a front cavity 202 for accommodating the ear, and a sealing plate 231 is disposed on the side of the earcup 23 facing the earphone shell 21, and a second vent 203 is disposed on the sealing plate 231, the second vent 203 communicating with the front cavity 202, and the second vent 203 cooperating with the first vent 201; When the second vent 203 is connected to the first vent 201, the earphone is in an open state. In this state, the second vent 203 and the first vent 201 allow the front cavity 202 to connect with the outside, enabling the ear inside the front cavity 202 to breathe and reducing stuffiness after prolonged use. When the second vent 203 and the first vent 201 are misaligned, the sealing plate 231 blocks the first vent 201, thus sealing the earphone. In this sealed state, the second vent 203 and the first vent 201 cannot connect the front cavity 202 with the outside, thus keeping the ear inside the front cavity 202 warm or providing a sealed environment to improve noise cancellation. Therefore, users can freely switch between the two states as needed to adapt to different user needs and environments, making the product very convenient and flexible to use, greatly enhancing the user experience.

[0040] In this embodiment, a first magnetic attractor 24 is provided on the earphone shell 21. Specifically, the earphone shell 21 includes a first shell 212 and a second shell 213; the second shell 213 is mounted on the first shell 212 and has a hollow annular structure; the acoustic component 22 is disposed on the first shell 211 via a connecting plate 211, and a portion of the acoustic component 22 is located in the middle of the second shell 213. An annular gap 204 exists between the second shell 213 and the acoustic component 22, and a dustproof mesh is installed at the annular gap 204 to cover the first vent 201, thereby improving aesthetics and providing dust protection. Furthermore, multiple limiting grooves 205 are provided around the center line at the edge of the first shell 212, and a first magnetic attractor 24 is installed in each limiting groove 205. The first magnetic attractor 24 is a magnet and has an arc-shaped sheet structure.

[0041] The earcup 23 is provided with a second magnetic member 25, and the earcup 23 is detachably mounted on the headphone shell 21 by magnetic attraction between the second magnetic member 25 and the first magnetic member 24. In this embodiment, please refer to... Figure 13As shown, the sealing plate 231 has multiple fixing slots 206 on the side facing the earcup 23. Each fixing slot 206 has a second magnetic member 25 installed in it. The second magnetic member 25 is a magnet and has an arc-shaped sheet structure. The second magnetic member 25 and the first magnetic member 24 magnetically engage to install the earcup 23 onto the headphone shell 21.

[0042] Furthermore, the first vent 201 and the second vent 203 are both symmetrically arranged, and both the first vent 201 and the second vent 203 are arc-shaped through holes. There are four first magnetic suction members 24, which are evenly distributed on the earphone shell 21 along the center line of the earphone body 20. There is a 90° interval between two adjacent first magnetic suction members 24. The second magnetic suction members 25 correspond one-to-one with the first magnetic suction members 24. After the ear cup 23 is removed from the earphone shell 21, the ear cup 23 is rotated 90° and then put back on the earphone shell 21, so that the earphone can switch from an open form to a sealed form, or from a sealed form to an open form.

[0043] Additionally, a soft plate 214 is provided on the side of the connecting plate 211 facing the earcup 23. The soft plate 214 is a silicone plate, made of silicone material, which has good durability and longevity. A sealing element 232 is provided on the sealing plate 231. When the earcup 23 is installed on the headphone shell 21, the sealing element 232 adheres to the soft plate 214, thereby sealing the earcup 23 and the headphone shell 21. At the same time, the sealing element 232 compresses the soft plate 214, and part of the structure of the sealing element 232 is embedded in the soft plate 214, thereby ensuring a sealing effect. For details, please refer to [link to details]. Figure 8 and Figure 9 As shown, the sealing element 232 includes a first sealing ring 2321, a second sealing ring 2322, and a sealing strip 2323. The first sealing ring 2321 is installed around the hole in the middle of the sealing plate 231. The second sealing ring 2322 is located at the edge of the sealing plate 231. Multiple sealing strips 2323 are provided, with each sealing strip 2323 having its two ends connected to the first sealing ring 2321 and the second sealing ring 2322, respectively. The sealing strip 2323, the first sealing ring 2321, and the second sealing ring 2322 form a ring that surrounds the periphery of the second vent hole 203, thereby sealing the area around the first vent hole 201. Furthermore, the sealing element 232 may be made of plastic, and a sealing groove 207 is provided in the middle of the sealing element 232. A silicone strip or a rubber strip (not shown in the figure) may be installed in the sealing groove 207 to allow the sealing element 232 to fit more tightly with the flexible plate 214, further improving the sealing performance. In other embodiments, the seal 232 can also be made of rubber or silicone.

[0044] In addition, please refer to Figure 10 and Figure 11As shown, the space in the middle of the earphone shell 21 is the rear cavity 208, and the acoustic component 22 is located in the rear cavity 208. A vent 209 is provided on the earphone shell 21, connecting to the rear cavity 208. This ensures pressure balance inside and outside the acoustic component 22, guaranteeing sound quality. Furthermore, the vent 209 does not affect the sound environment of the rear cavity 208 in its open or sealed state, further ensuring sound quality. The vent 209 also does not affect the placement of components such as the speaker and PCBA, allowing for multiple design options and ultimately optimizing the earphone structure. The form-switching design of this application only seals the front cavity 202 at the earcup 23, while the rear cavity 208 remains stable. Therefore, sealing only a single chamber ensures a good seal, thereby guaranteeing sound quality.

[0045] When the headphones of this application are in use, after the user wears the product on the head, the user's ears will be housed in the front cavity 202 of the headphone body 20. When the ears need to breathe, the earcups 23 are installed on the headphone shell 21, and the second vent 203 is connected to the first vent 201. The headphones are in an open state. At this time, the second vent 203 and the first vent 201 can connect the front cavity 202 with the outside world, so that the ears located in the front cavity 202 can breathe, reducing the stuffiness problem after wearing and using for a long time. When the ears need to be kept warm or a sealed environment is needed to improve the noise cancellation effect of the headphones, the earcups 23 are rotated at an angle and then installed on the headphone shell 21, so that the second vent 203 is misaligned with the first vent 201. The sealing plate 231 blocks the first vent 201, thus sealing the headphones. The headphones are in a sealed state. At this time, the second vent 203 and the first vent 201 cannot connect the front cavity 202 with the outside world, thereby keeping the ears in the front cavity 202 warm or providing a sealed environment to improve the noise cancellation effect of the headphones.

[0046] Example 2:

[0047] The specific structure of this embodiment is basically the same as that of the aforementioned embodiment one. The difference is that in this embodiment, the earcups 23 and the headphone shell 21 are detachably connected by a snap-fit ​​structure. The snap-fit ​​structure includes snap-fit ​​blocks 215 and snap-fit ​​slots 2311. The snap-fit ​​blocks 215 are disposed on the headphone shell 21, and the snap-fit ​​slots 2311 are disposed on the sealing plate 231. The snap-fit ​​blocks 215 and the snap-fit ​​slots 2311 are engaged to allow the earcups 23 to be detachably installed on the headphone shell 21. Furthermore, there are multiple snap-fit ​​blocks 215 arranged at equal intervals around the circumference, and correspondingly, there are also multiple snap-fit ​​slots 2311 arranged at equal intervals around the circumference, which is not limited to this.

[0048] Therefore, the detachable mounting structure between the earcup 23 and the headphone shell 21 is not limited and can be any other structure. The earcup 23 can also be rotatably mounted on the headphone shell 21 relative to the headphone shell 21 to change the position of the second vent 203 as needed, so that the second vent 203 is directly opposite or misaligned with the first vent 201, without limitation.

[0049] Compared with the prior art: This application provides an open-back headphone, including: a headband 10 and two earphone bodies 20; the two earphone bodies 20 are respectively installed on both sides of the headband 10, and at least one earphone body 20 includes an earphone shell 21, an acoustic component 22, and an earcup 23; a first vent 201 communicating with the outside is provided on the connecting plate 211 of the earphone shell 21, and a second vent 203 is provided on the sealing plate 231 of the earcup 23, and the earcup 23 is detachably or movably mounted on the earphone shell 21. When the second vent 203 is opened, the earcup 203 communicates with the outside. When the second vent 203 is connected to the first vent 201, the earphone is in an open state, allowing the ears to breathe and solving the problem of stuffiness. When the second vent 203 is misaligned with the first vent 201, the sealing plate 231 blocks the first vent 201, allowing the earphone to switch from an open state to a sealed state. This can keep the ears warm or provide a sealed environment to improve the noise reduction effect of the earphone. Therefore, users can freely switch between the two states as needed to adapt to the needs of different users and different environments. The product is very convenient and flexible to use, greatly improving the user experience.
