Description

Technical Field

[0001] This utility model belongs to the field of headphone technology, and in particular relates to an ear cover structure and a headphone. Background Technology

[0002] Because headphones exert pressure on the user's face and ears when worn, most headphones have ear tips attached to the earpiece. These ear tips cover the user's ears, increasing the softness of the contact between the headphones and the face, while also improving the fit between the headphones and the ear, reducing sound leakage and enhancing sound quality. However, existing ear tip designs suffer from significant fluctuations in air permeability, leading to instability in the headphone's passive noise cancellation curve and severely impacting its acoustic performance. Utility Model Content

[0003] The purpose of this invention is to provide an ear cup structure and headphones, aiming to solve the technical problem of large fluctuations in air permeability in existing ear cup structures during use.

[0004] This utility model is implemented as follows: Firstly, it provides an ear cover structure, comprising:

[0005] The ear cover body includes an elastic loose body and a covering sleeve, the covering sleeve covering the outside of the elastic loose body, the covering sleeve having an outer fabric layer and a sealing inner layer connected to the inside of the outer fabric layer;

[0006] A support member is attached to the side of the ear cup body to support the ear cup body.

[0007] In one alternative embodiment, an adhesive is provided between the outer fabric layer and the inner sealing layer, and the outer fabric layer and the inner sealing layer are formed by hot pressing.

[0008] In an optional embodiment, the cover is provided with an exhaust hole, and the exhaust hole is also covered with a perforated filter screen for adjusting the amount of air escaping from the exhaust hole.

[0009] In one optional embodiment, a connecting flange is provided around the periphery of the ear cup body, the connecting flange is provided along the circumference of the ear cup body, the ear cup body is connected to a first side of the support member, and the connecting flange is connected to a second side of the support member.

[0010] In an optional embodiment, a PET pad is further provided between the ear cup body and the first side of the support member, with one side of the PET pad being attached to the first side of the support member and the other side of the PET pad being attached to the side of the ear cup body.

[0011] In an optional embodiment, the support member has a sound outlet hole for sound to pass through, and the ear cover body also has an ear cover hole for accommodating the user's ear. The position of the ear cover hole matches the position of the sound outlet hole, and the sound outlet hole is also covered with an ear cover mesh.

[0012] In one alternative embodiment, the edge of the earcup mesh is adhered to the periphery of the sound outlet and is adhered to the same side of the support member as the earcup body.

[0013] In an optional embodiment, the support member is provided with a snap-fit ​​assembly for snapping the support member onto the headphone body.

[0014] In an optional embodiment, the mounting assembly includes a mounting slot disposed on the support member, and the earphone body is provided with a protruding mounting portion for engaging with the mounting slot. The mounting slot includes a clearance portion and a mounting portion. The clearance portion is used to allow the protruding mounting portion to pass through, and the mounting portion is used to fix the protruding mounting portion to the support member.

[0015] In a second aspect, an earphone is provided, comprising the ear cover structure described in any of the preceding claims.

[0016] The technical advantages of this invention compared to existing technologies are as follows: A cover sleeve, composed of an outer fabric layer and a sealing inner layer, is used to wrap around an elastic, porous material to form the earcup body. A support structure is also connected to the side of the earcup body for added support. Compared to existing earcup structures, placing the outer fabric layer on the outside of the cover sleeve improves comfort and skin-friendliness when the earcup body is in contact with the skin. The sealing inner layer, composited within the outer fabric layer, provides a degree of barrier function, avoiding the large fluctuations in breathability that can occur with a separate outer fabric layer, thus maintaining stable breathability of the earcup body. While ensuring a tight seal and skin-friendliness, the stable sound absorption and reflection coefficients of the elastic, porous material within the cover sleeve guarantee a stable passive noise reduction curve for the headphones, thereby improving their acoustic performance.

[0017] It is understandable that the beneficial effects of the second aspect mentioned above can be found in the relevant descriptions in the first aspect mentioned above, and will not be repeated here. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0032] Please refer to Figures 1 to 3 As shown, in a first aspect of this utility model embodiment, an ear cup structure is provided, the ear cup structure including an ear cup body 1 and a support member 2. The ear cup body 1 includes an elastic loose body 12 and a covering sleeve 11, the covering sleeve 11 covering the outside of the elastic loose body 12, and the covering sleeve 11 having an outer fabric layer 111 and a sealing inner layer 112 connected to the inner side of the outer fabric layer 111. The support member 2 is connected to the side of the ear cup body 1 and is used to support the ear cup body 1.

[0033] Specifically, the support component 2 refers to a plate-shaped component with a certain thickness, and the support component 2 itself has a certain rigidity. The support component 2 can be connected to the ear cover body 1 by pasting or heat pressing.

[0034] The elastic loose body 12 refers to a component with a certain degree of elasticity and a loose internal structure. The elastic loose body 12 can be a sponge, a limiting assembly, or polyurethane foam, etc. The elastic loose body 12 can be a ring structure as a whole, and the cross-section of the elastic loose body 12 can be circular, rectangular, or polygonal, etc. By covering the outside of the elastic loose body 12 with the cover 11, an ear cover body 1 with the same shape as the elastic loose body 12 is formed. It can be placed on the outside of the user's ear when the headphones are worn, and can also come into contact with the user's face.

[0035] The covering sleeve 11 refers to a thin-walled structure with a certain area. By covering the elastic porous body 12 with the covering sleeve 11, it can protect the elastic porous body 12. The covering sleeve 11 includes an outer fabric layer 111 and a sealing inner layer 112. The outer fabric layer 111 can be any of woven fabric, fleece, or microfiber fabric. The sealing inner layer 112 can be a thin film structure, and its material can be TPU (Thermoplastic Polyurethane), TPE (Thermoplastic Elastomer), PU (Polyurethane), PE (Polyethylene), PET (Polyethylene terephthalate), PEN (Polyethylenenaphthalate), PEEK (Polyetheretherketone), PAR (Polyarylate), etc. The outer fabric layer 111 and the sealing inner layer 112 can be bonded together by adhesive or heat pressing, or they can be bonded together by a combination of adhesive and heat pressing to form a covering sleeve 11.

[0036] The ear cover structure provided in this embodiment of the utility model is a cover 11 composed of an outer fabric layer 111 and a sealing inner layer 112. The cover 11 is wrapped around the outside of an elastic loose body 12 to form an ear cover body 1. A support body is also connected to the side of the ear cover body 1 to support it. Compared with the ear cover structure in the prior art, by placing the outer fabric layer 111 on the outside of the cover 11, the comfort and skin-friendliness of the ear cover body 1 when in contact with the skin can be improved. At the same time, the sealing inner layer 112 is laminated on the inside of the outer fabric layer 111 to form the cover 11, which can play a certain barrier role on the basis of the outer fabric layer 111. This can avoid the problem of large fluctuations in air permeability caused by using the outer fabric layer 111 alone, and keep the air permeability of the ear cover body 1 stable. While ensuring the earphones are sealed and skin-friendly, the sound absorption coefficient and reflection coefficient of the elastic porous body 12 set inside the cover 11 are kept stable, which ensures the stability of the passive noise reduction curve of the earphones and thus improves the acoustic performance of the earphones.

[0037] In an optional embodiment, please refer to Figure 3 The inner layer has a thickness of 5um-100um, which can ensure the overall softness of the ear cover body 1 meets the requirements, while also being easy to hot press.

[0038] In one embodiment, see Figure 3 An adhesive is present between the outer fabric layer 111 and the inner sealing layer 112, and the outer fabric layer 111 and the inner sealing layer 112 are formed by hot pressing. Specifically, the adhesive refers to a material that can bond two or more objects together; the adhesive can be an organic adhesive or an inorganic adhesive, etc. Hot pressing is a method of bonding materials by heating and applying pressure, usually achieved by a hot press. In this embodiment, by applying adhesive between the outer fabric layer 111 and the inner sealing layer 112, and simultaneously using hot pressing to bond the outer fabric layer 111 and the inner sealing layer together, the bond between the outer fabric layer 111 and the inner sealing layer is made stronger, thereby improving the overall strength of the cover 11.

[0039] In an optional embodiment, please refer to Figure 3 The adhesive can be epoxy resin glue. Specifically, epoxy resin glue is an important adhesive whose main component is epoxy resin. Epoxy resin is a polymer compound containing epoxy groups, with two or more epoxy groups in its molecular chain. These epoxy groups can chemically react with the curing agent to form a cured product with a three-dimensional network structure. By applying epoxy resin glue between the sealing inner layer 112 and the outer layer, the bond between the two can be made stronger.

[0040] In one embodiment, see Figure 4The cover 11 has an exhaust hole 13, and a perforated filter 14 for adjusting the airflow at the exhaust hole 13 is also provided. Specifically, the exhaust hole 13 refers to a perforated structure with a certain area, and the exhaust hole 13 generally extends through the entire thickness of the cover 11. The perforated filter 14 refers to a filter structure with a certain area, and the edge of the perforated filter 14 can be connected to the cover 11 by means of adhesive bonding, heat pressing, or other methods. By providing an exhaust hole 13 on the cover 11, when the earpiece body 1 is compressed, the gas generated by the pressure of the elastic loose body 12 can be discharged from the exhaust hole 13, preventing the gas inside the cover 11 from not being discharged in time and affecting the softness of the elastic loose body 12, making the earpiece structure more comfortable to wear. At the same time, the perforated filter 14 is also provided at the exhaust hole 13, which can slow down the airflow at the exhaust hole 13, thereby reducing the noise during the compression and exhaust process, reducing interference with sound quality, and improving the wearer's experience.

[0041] It should be noted that, in order to avoid the vent 13 affecting the appearance of the cover 11, the vent 13 can be located on the side of the ear cover body 1 facing the support member 2. When the ear cover body 1 is connected to the support member 2, the vent 13 can be covered so that the vent 13 is not exposed. At the same time, a clearance structure can also be provided on the support member 2, and the position of the vent 13 is opposite to the clearance structure on the support member 2 to avoid covering the vent 13 and affecting the venting effect.

[0042] In an optional embodiment, please refer to Figure 4 The earpiece body 1 has multiple vent holes 13, which are evenly distributed along its circumference. Preferably, there are two vent holes 13, located at the top and bottom of the earpiece body 1, respectively. By evenly distributing the vent holes 13 along the circumference of the earpiece body 1, the air venting rate is ensured to be the same throughout the earpiece body 1, preventing localized differences in hardness between the earpiece body 1 and other parts, thus making the earpiece body 1 more comfortable to use.

[0043] In one embodiment, see Figure 3 and Figure 4The earpiece body 1 has a connecting flange 15 around its periphery. The connecting flange 15 is arranged circumferentially around the earpiece body 1. The earpiece body 1 is connected to the first side of the support member 2, and the connecting flange 15 is connected to the second side of the support member 2. Specifically, the connecting flange 15 is a sheet-like component with a certain width, and the length direction of the connecting flange 15 can be arranged circumferentially around the earpiece body 1. The first side and the second side refer to two different sides on the support member 2. When the support member 2 is a plate-like structure, the first side and the second side refer to two plate surfaces arranged opposite each other on the support member 2. In this embodiment, by providing the connecting flange 15 around the periphery of the earpiece body 1, when the earpiece body 1 is connected to the first side of the support member 2 by means of adhesive or heat pressing, the connecting flange 15 can also be connected to the second side of the support member 2 by means of adhesive or heat pressing. This increases the connection area between the earpiece body 1 and the support member 2, making the connection between the earpiece body 1 and the support member 2 more secure, and also increasing the overall stability of the entire earpiece structure.

[0044] In an optional embodiment, please refer to Figure 3 The connecting flange 15 and the covering sleeve 11 on the ear cover body 1 are integrally formed. When the covering sleeve 11 covers the outside of the elastic loose body 12, at least part of the edge of the covering sleeve 11 can be extended in a direction away from the elastic loose body 12 to form the connecting flange 15. This can make the connection between the connecting flange 15 and the ear cover body 1 more secure without damaging the overall integrity of the covering sleeve 11.

[0045] In one embodiment, see Figure 3 A PET pad 3 is also provided between the earcup body 1 and the first side of the support member 2. One side of the PET pad 3 is attached to the first side of the support member 2, and the other side of the PET pad 3 is attached to the side of the earcup body 1. Specifically, the PET pad 3 refers to a plate or sheet structure made of PET (Polyethylene terephthalate) material, and the shape of the PET pad 3 can be adapted to the shape of the support member 2. In this embodiment, the PET pad 3 between the earcup body 1 and the first side of the support member 2 can act as a barrier to protect the entire earcup structure, preventing external dust, dirt, and other impurities from entering the earcup and protecting the internal materials of the earcup from contamination. In addition, the PET pad 3 can also reflect or scatter sound to a certain extent, helping to adjust the acoustic environment inside the earcup, optimize the frequency response of the sound, and make the sound emitted by the headphones clearer and more balanced.

[0046] In an optional embodiment, please refer to Figure 3The side of the PET pad 3 can be glued to the first side of the support member 2 using adhesive, and the cover 11 on the ear cup body 1 can also be glued to the other side of the PET pad 3 using adhesive. Specifically, adhesive refers to a material that can bond two or more objects together. The adhesive can be organic or inorganic, and 3M adhesive can be used. By using adhesive to connect the PET pad 3 to the ear cup body 1 and the support member 2 respectively, the installation of the PET pad 3 is more convenient and secure, and the overall structure of the ear cup is more stable.

[0047] In one embodiment, see Figure 2 The support member 2 has a sound outlet hole 4 for sound to pass through, and the earpiece body 1 also has an earpiece hole 16 for accommodating the user's ear. The position of the earpiece hole 16 matches the position of the sound outlet hole 4, and an earpiece mesh 5 is also provided to cover the sound outlet hole 4. Specifically, the sound outlet hole 4 refers to a hole structure with a certain area, and the earpiece mesh 5 refers to a mesh structure with a certain area. In this embodiment, by providing a sound outlet hole 4 for sound to pass through on the support member 2, and by matching the position of the earpiece hole 16 with the position of the sound outlet hole 4, the sound generated by the sound unit on the headphones can be allowed to enter the earpiece body 1 through the sound outlet hole 4. At the same time, the earpiece mesh 5 is also provided to cover the sound outlet hole 4, which can prevent dust and other debris from entering the earpiece body 1 without affecting the sound passage of the sound unit, thereby making the use of the headphones safer and more reliable.

[0048] In an optional embodiment, please refer to Figure 2 The earcup mesh fabric 5 has an air permeability greater than 2200mm / s. Specifically, air permeability refers to the volume of air passing through a unit area of ​​material per unit time under a certain pressure difference. By ensuring that the earcup mesh fabric 5 has an air permeability greater than 2200mm / s, it is possible to ensure that the earcup mesh fabric 5 can block dust without blocking too many high-frequency components, thus improving the acoustic performance of the headphones.

[0049] In one embodiment, see Figure 2The edge of the earpiece mesh 5 is pasted around the sound outlet 4 and is pasted on the same side of the support member 2 as the earpiece body 1. Specifically, the earpiece mesh 5 and the earpiece body 1 are respectively connected to different areas on the same side of the support member 2. For example, the area where the edge of the earpiece mesh 5 is pasted to the support member 2 can be defined as the first area, and the area where the earpiece body 1 is pasted to the support member 2 can be defined as the second area. The second area can surround the first area. In this embodiment, the edge of the earpiece mesh 5 and the earpiece body 1 can be pasted to the same side of the support member 2. When assembling the earpiece structure, the edge of the earpiece mesh 5 is first pasted to the support member 2, and then the earpiece body 1 is pasted to other areas on the same side of the support member 2. The earpiece body 1 can block the area where the edge of the earpiece mesh 5 is pasted to the support member 2, making the overall appearance of the earpiece structure more aesthetically pleasing after the earpiece mesh 5 is installed. Meanwhile, the earcup mesh 5 can be in the shape of a bowl that matches the shape of the headphone's speaker cover. After the edge of the earcup mesh 5 is pasted to one side of the support 2, most of the earcup mesh 5 can extend through the sound outlet 4 to the other side of the support 2. This not only ensures that the headphone looks more beautiful, but also improves the comfort of wearing the headphone and the flexibility of wearing and removing the headphone.

[0050] It should be noted that the area where the edge of the ear cover mesh 5 connects to the support member 2 can be defined as the first area, and the area where the ear cover body 1 connects to the support member 2 can be defined as the second area. The second area can be set around the first area, so that the overall structural layout of the ear cover structure can be more reasonable.

[0051] In an optional embodiment, please refer to Figure 2 The edges of the earmuff mesh 5 are bonded to the support member 2 by heat pressing. Specifically, heat pressing is a method of bonding materials by heating and applying pressure, usually achieved using a hot press. In this embodiment, the earmuff mesh 5 is connected to the support member 2 by heat pressing, which makes the installation and fixation of the earmuff mesh 5 more convenient and secure.

[0052] In one embodiment, see Figure 5 and Figure 6 The support member 2 is provided with a snap-fit ​​component 6, which is used to snap-fit ​​the support member 2 to the earphone body 7. Specifically, the snap-fit ​​component 6 refers to a component or structure that snaps together two parts. In this embodiment, by providing the snap-fit ​​component 6 on the support member 2, the ear tip structure can be snapped together to the earphone body 7 during installation, making the installation of the ear tip structure more convenient and quick, and also making it easier to disassemble when the ear tip structure needs to be replaced.

[0053] In one embodiment, see Figure 6The mounting assembly 6 includes a mounting slot 61 disposed on the support member 2. The earphone body 7 is provided with a protruding locking part 8 for engaging with the mounting slot 61. The mounting slot 61 includes a clearance part 611 and a locking part 612. The clearance part 611 is used to allow the protruding locking part 8 to pass through, and the locking part 612 is used to lock and fix the protruding locking part 8 to the support member 2. Specifically, the mounting slot 61 refers to a slot structure with a certain length. The length direction of the mounting slot 61 can be set along a straight line or along an arc. The clearance part 611 and the locking part 612 refer to the two parts of the mounting slot 61 along the length direction, respectively. The clearance part 611 and the locking part 612 are interconnected, and the width of the clearance part 611 can be greater than the width of the locking part 612. The protruding locking part 8 refers to a component with a certain height. A locking block or locking plate can be provided at the end of the protruding locking part 8. In this embodiment, when the support member 2 needs to be snapped into the headphone body 7, the protruding snap-fit ​​part 8 can be inserted into the clearance part 611 of the snap-fit ​​slot 61, and then the support member 2 can be moved in a straight line or rotated in an arc relative to the headphone body 7, so that the protruding snap-fit ​​part 8 can slide into the snap-fit ​​part 612 along the length direction of the snap-fit ​​slot 61, and finally the protruding snap-fit ​​part 8 and the snap-fit ​​slot 61 are snapped into each other, so that the installation and disassembly of the support member 2 can be more convenient.

[0054] In an optional embodiment, please refer to Figure 6 The number of mounting slots 61 can be multiple, and these slots 61 can be evenly arranged around the axis of the support member 2. Simultaneously, multiple protruding locking parts 8 are also provided on the earphone body 7, and the number and position of the protruding locking parts 8 match those of the mounting slots 61. Specifically, when the support member 2 and the earphone body 7 are connected, the protruding locking parts 8 can first be inserted into the mounting slots 61, and then the support member 2 can be rotated around its own axis to achieve mutual locking between the protruding locking parts 8 and the mounting slots 61, making the locking of the support member 2 and the earphone body 7 more convenient and more secure.

[0055] Secondly, an earphone is provided, including the ear cup structure described above. The support member 2 is connected to the earphone body 7 via a snap-fit ​​assembly 6. The ear cup body 1 is formed by a cover 11 composed of an outer fabric layer 111 and a sealing inner layer 112, which is then wrapped around the elastic porous body 12. A support body is also connected to the side of the ear cup body 1 to provide support. By placing the outer fabric layer 111 on the outside of the cover 11, the comfort and skin-friendliness of the ear cup body 1 when in contact with the skin can be improved. Simultaneously, the sealing inner layer 112, laminated inside the outer fabric layer 111 to form the cover 11, provides a certain degree of barrier function on top of the outer fabric layer 111, avoiding the problem of large fluctuations in breathability caused by using the outer fabric layer 111 alone. While ensuring the earphones are sealed and skin-friendly, the sound absorption coefficient and reflection coefficient of the elastic porous body 12 set inside the cover 11 are kept stable, which ensures the stability of the passive noise reduction curve of the earphones and thus improves the acoustic performance of the earphones.

[0056] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way.
