Description

Technical Field

[0001] The present application relates to the technical field of earphones, and in particular to an earmuff, an earphone receiver and a headset. Background Art

[0002] Due to the advantages of headphones such as comfortable wearing and good sound quality, they are favored by many consumers in the market. With the continuous development of headphones, headphones have become an indispensable product component in the headphone industry.

[0003] However, currently when users use headphones, a certain amount of heat will be generated at the contact point between the user's ear and the earmuff body after long-term use, and the heat generated at the contact point cannot be well dissipated to the outside world, so that the user's ears will feel stuffy when wearing them for too long, affecting the user's usage experience. Summary of the invention

[0004] The embodiments of the present application provide an earmuff, an earphone receiver, and a headset, which can improve the heat dissipation efficiency at the earmuff position during the wearing of the headset, thereby improving the comfort of use.

[0005] In a first aspect, an embodiment of the present application provides an earmuff, which is applied to a headset, and the earmuff includes:

[0006] a flexible support body, arranged in an annular shape, comprising an inner annular surface, an outer annular surface, a first support surface and a second support surface, wherein the first support surface and the second support surface are connected between the inner annular surface and the outer annular surface and are arranged opposite to each other, and the first support surface is arranged facing the ear shell of the earphone; and

[0007] A heat-conducting member, wrapped around the flexible support body, wherein a portion of the heat-conducting member corresponding to the first support surface can transfer heat from the earmuff to the ear shell;

[0008] The heat conducting member is provided with a plurality of slots, and the plurality of slots are configured to be arranged at intervals along the circumference of the flexible support body when the heat conducting member wraps the flexible support member.

[0009] Based on the earmuffs of the embodiments of the present application, by providing a heat-conducting member covering the flexible support body, the heat located at the earmuff position during the wearing of the headset can be quickly transferred to the ear shell through the portion of the heat-conducting member corresponding to the first supporting surface of the flexible support body. Compared with the existing headsets that are not provided with heat-conducting members for natural heat dissipation, the heat of the earmuff part of the solution of the present application is conducted by the heat-conducting member, and the heat dissipation efficiency is significantly improved.

[0010] At the same time, the present application further forms a plurality of grooves on the heat conductor that are arranged at intervals along the circumference of the flexible support body. In this way, in the process of the heat conductor covering the flexible support body, the air between the heat conductor and the outer wall surface of the flexible support body can be effectively discharged from the grooves, making the overall structure of the heat conductor easier to unfold, and the heat conductor can be better flattened and tightly attached to the outer wall surface of the flexible support body. It can be seen that the scheme of the present application can greatly reduce the possibility of wrinkling when the heat conductor covers the flexible support body, that is, it greatly reduces the possibility of a cavity between the heat conductor and the outer wall surface of the flexible support body, thereby forming an effective surface contact between the heat conductor and the outer wall surface of the flexible support body, and the heat conduction area is correspondingly maximized, so that the heat of the earmuff part can be more efficiently transferred to the ear shell for dissipation, thereby improving the comfort of the headphones.

[0011] In a second aspect, an embodiment of the present application provides an earphone receiver, comprising the earmuff and ear shell as described above.

[0012] In a third aspect, an embodiment of the present application provides a headset, comprising a head mounted device and two earphone receivers as described above, wherein shells of the two earphone receivers are respectively connected to opposite ends of the head mounted device.

[0027] In order to make the objectives, technical solutions and advantages of the present application clearer, the following part will further describe the embodiments of the present application in detail in conjunction with the accompanying drawings.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0031] See also Figure 1 In one aspect, the present application proposes a headset 500, which includes a head-mounted device and two earphone receivers 300, and the two earphone receivers 300 are respectively connected to opposite ends of the head-mounted device. During use, the head-mounted device is used to be worn on the user's head, and when the head-mounted device is worn on the user's head, the two earphone receivers 300 can cover the user's left ear and right ear respectively, so that the sound emitted by the earphone receivers 300 can enter the user's ears. It should be noted that the head-mounted device can be worn on the top of the user's head or on the back of the user's head, and the present application does not limit this.

[0032] In order to quickly dissipate the heat generated at the contact position between the earphone receiver 300 and the ear of the user when the user wears the headset 500, the present application further proposes an earphone receiver 300, see Figure 1 In the embodiment of the present application, the earphone receiver 300 includes an ear shell 310, an earmuff 100 and a sound-generating device (not shown), the ear shell 310 includes a shell 320 and a heat sink 330, the earmuff 100 is connected to the shell 320, the heat sink 330 is connected to the shell 320, and is located on the side of the shell 320 facing the earmuff 100, the heat sink 330 is in contact with the earmuff 100, so that the heat generated by the earmuff 100 is transferred to the heat sink 330 and then dissipated to the outside.

[0033] The shell 320 is the external shell structure of the ear shell 310, and a housing cavity is formed in the shell 320, which is used to accommodate the sound-emitting device. The sound emitted by the sound-emitting device can enter the user's ear through the shell 320 and the earmuff 100. The specific working principle of the sound-emitting device has long been disclosed in the relevant technology, and this application will not go into details. That is, the earphone receiver 300 has a traditional sound playback function. Among them, the shell 320 can be made of plastic material, so that it can be produced by injection molding, so that the shell 320 is easy to shape, and the shell 320 made of plastic material can be made lighter, reducing the weight burden on the ear when the user wears the headset 500, and improving the user experience. Of course, the shell 320 can also be made of metal material, and this application does not limit this.

[0034] When the heat sink 330 is in contact with the earmuff 100, the heat generated by the earmuff 100 can be dissipated to the outside through the heat sink 330, that is, the heat sink 330 has good heat dissipation performance, so that the heat can be quickly dissipated to the outside after being transferred to the heat sink 330. Specifically, the heat sink 330 can be a metal part, for example, a metal part with good heat dissipation performance such as aluminum alloy, copper or iron. In addition, the heat sink 330 can be annular, so that the heat transferred from the earmuff 100 can be dissipated in the circumferential direction, thereby improving the heat dissipation efficiency.

[0035] In order to further quickly dissipate the heat generated by the earmuff 100 when the user's ear is in contact with the earmuff 100, the present application focuses on improving the earmuff 100. Figures 2 to 4 In the embodiment of the present application, the earmuff 100 includes a flexible support body 10, a cover body 30, a heat conductor 50 and a connector 70. The flexible support body 10 is arranged in a ring shape, and the cover body 30 is sleeved on the outside of the flexible support body 10 and the connector 70. The heat conductor 50 wraps the flexible support body 10 and the connector 70. The connector 70 is fixed between the flexible support body 10 and the heat conductor 50, and is used to cooperate with the ear shell 310 for connection.

[0036] When the flexible support body 10 is wrapped by the cover body 30, its good flexibility can provide support between the user's ear and the shell 320 of the ear shell 310, thereby increasing wearing comfort. Specifically, the flexible support body 10 can be a sponge, and the permeability of the sponge can reduce the loss of sound from the sound-generating device of the ear shell 310 during transmission, effectively reducing sound leakage and improving the hearing effect. Figures 5 and 6The flexible support body 10 may be arranged in a ring shape, and the ring-shaped flexible support body 10 may include an inner ring surface 11, an outer ring surface 13, a first support surface 15 and a second support surface 17. The first support surface 15 and the second support surface 17 are connected between the inner ring surface 11 and the outer ring surface 13 and are arranged opposite to each other. The first support surface 15 is arranged facing the ear shell 310 of the earphone (headphone 500), and the connecting member 70 is fixed to the first support surface 15 and exposed by the opening 30a, and a portion of the heat conductive member 50 covers the side of the connecting member 70 close to the ear shell 310.

[0037] The cover 30 can be used to cover the user's ears and will contact the user's ears. The cover 30 may include a contact surface 31 for contacting the user's ears. The ears may be the skin of the ears or the surroundings of the ears. That is, when the ears of some users are larger, the contact surface 31 is the surface of the skin that contacts the user's ears; and when the ears of some users are smaller, the ears of these users will be located in the avoidance holes of the cover 30. At this time, the contact surface 31 is the surface that contacts the surroundings of the user's ears. The contact surface 31 will generate a certain amount of heat when in contact with the ears, resulting in a certain amount of heat on the cover 30. Even if the cover 30 is made of a leather material or PU (Poly Urethane) leather material with good air permeability, the heat cannot be well dissipated after long-term use, resulting in a stuffy feeling in the user's ears, affecting the user's experience. The cover 30 is formed with an opening 30a corresponding to the first support surface 15, and the portion of the heat-conducting member 50 covering the first support surface 15 is exposed by the opening 30a, so that the portion of the heat-conducting member 50 can contact the ear shell 310. Furthermore, the opening 30a of the cover body 30 is formed at a position corresponding to the first supporting surface 15, and the opening 30a can correspond to the installation position of the heat sink 330, that is, when the heat sink 330 is connected to the connection between the cover body 30 and the shell 320, the distance between the heat conductor 50 and the heat sink 330 is the shortest when the abutment is achieved. In other words, the heat at the contact surface 31 can be conducted to the heat sink 330 via the shortest path between the heat conductor 50 and the heat sink 330, and then dissipated to the outside by the heat sink 330, thereby improving the heat dissipation effect of the heat at the contact surface 31 of the cover body 30 of the earmuff 100.

[0038] The heat conductive member 50 is disposed to wrap the flexible support body 10. Specifically, the heat conductive member 50 may cover the outer annular surface 13, the first support surface 15, the second support surface 17, and the inner annular surface 11, or the heat conductive member 50 may cover the outer annular surface 13, the first support surface 15, and the second support surface 17. The present application does not limit this. The portion of the heat conductive member 50 corresponding to the first support surface 15 may be used to transfer the heat of the earmuff to the heat sink 330 of the ear shell 310.

[0039] In one embodiment, the heat conducting member 50 may be a graphene heat conducting sheet, for example, a sheet structure of graphene material. Of course, the heat conducting member 50 may also be other materials with similar properties to the graphene material, and the present application does not limit this. Among them, the graphene heat conducting sheet has good thermal conductivity, and the thermal conductivity of a good single-layer graphene can be as high as 5300W / mK, which is a carbon material with a high thermal conductivity. Of course, the heat conducting member 50 may also be a heat conducting silicone structure, a heat conducting silver glue structure or a metal structure, and the present application does not limit this.

[0040] Please refer to Figure 7 and Fig.10 The heat conductive member 50 is provided with a plurality of slots 50a, and the plurality of slots 50a are arranged to be spaced apart along the circumference of the flexible support member 10 when the heat conductive member 50 wraps the flexible support member 10. The slots 50a may be in a rectangular, triangular, or fan-shaped shape, etc., and the specific shape of the slots 50a is not limited in the present application. In addition, the slots 50a may extend from the middle portion of the heat conductive member 50 to the edge of the heat conductive member 50 to prevent the heat conductive member 50 from wrinkling. In this way, under the setting of the groove 50a, when the heat conductive member 50 wraps the outer ring surface 13 and the first supporting surface 15, if the heat conductive member 50 is wrinkled during wrapping, the contact area between the heat conductive member 50 and the cover body 30 will be reduced. Under the setting of the groove 50a, the heat conductive member 50 itself can have a certain deformation amount, that is, under the existence of the groove 50a, the heat conductive member 50 can be flattened, thereby ensuring that the surface of the heat conductive member 50 is flat, so that the contact area between the heat conductive member 50 and the cover body 30 is larger, thereby allowing heat to be better transferred to the heat conductive member 50, so that the heat conductive member 50 can further transfer the heat to the heat sink 330 of the ear shell 310.

[0041] Based on the earmuff 100 of the embodiment of the present application, a heat conductive member 50 covering the flexible support body 10 is provided. When the headphone 500 is worn, the heat located at the position of the earmuff 100 can be quickly transferred to the ear shell 310 through the portion of the heat conductive member 50 corresponding to the first support surface 15 of the flexible support body 10. Compared with the existing headphone which is not provided with a heat conductive member 50 for natural heat dissipation, the heat dissipation efficiency of the earmuff 100 in the solution of the present application is significantly improved due to the conduction of the heat conductive member 50.

[0042] At the same time, the present application further forms a plurality of grooves 50a on the heat conductive member 50, which are arranged at intervals along the circumference of the flexible support body 10. In this way, in the process of the heat conductive member 50 covering the flexible support body 10, the air between the heat conductive member 50 and the outer wall surface of the flexible support body 10 can be effectively discharged from the grooves 50a, so that the overall structure of the heat conductive member 50 is easier to unfold, and the heat conductive member 50 can be better flattened and tightly attached to the outer wall surface of the flexible support body 10. It can be seen that the scheme of the present application can greatly reduce the possibility of wrinkling when the heat conductive member 50 covers the flexible support body 10, that is, it greatly reduces the possibility of a cavity between the heat conductive member 50 and the outer wall surface of the flexible support body 10, so that an effective surface contact is formed between the heat conductive member 50 and the outer wall surface of the flexible support body 10, and the heat conduction area is correspondingly maximized, so that the heat of the earmuff 100 can be more efficiently transferred to the ear shell 310 for dissipation, thereby improving the comfort of the headphones 500.

[0043] It can be understood that when the heat conductive member 50 is configured as a graphene heat conductive sheet, it has the advantage of better heat dissipation effect. Of course, the heat conductive member 50 of the present application can also be the heat conductive silicone structure, heat conductive silver glue structure or metal structure described above, so that the production cost of the heat conductive member 50 can be reduced. Next, the heat conductive member 50 is still configured as a graphene heat conductive sheet to further explain the situation in which the heat generated at the contact position between the cover body 30 of the earmuff 100 of the present application and the user's ear can be quickly dissipated.

[0044] Please refer to Figures 7 to 10 The heat conducting member 50 includes a base 55 and a plurality of heat conducting sheets 53, wherein the plurality of heat conducting sheets 53 are connected to the base 55, and the plurality of heat conducting sheets 53 are arranged along the extension direction of the base 55, and a slot 50a is formed between two adjacent heat conducting sheets 53. The base 55 can be arranged in a strip shape or in a circular shape, which is not specifically limited. The plurality of heat conducting sheets 53 are connected to the side of the base 55, which can be the same side of the base 55 or different sides of the base 55, which is not specifically limited.

[0045] In one embodiment, see Figure 7 The substrate 55 is in a long strip shape and is arranged around the outer ring surface, and the substrate 55 covers part of the outer ring surface 13. In the actual wrapping process, the outer ring surface 13 can be partially covered by the long strip substrate 55, that is, after the outer ring surface 13 is wrapped by the substrate 55, the two ends of the substrate 55 along the length direction can be connected to achieve coverage of the outer ring surface 13.

[0046] The heat conducting sheet 53 includes a plurality of first heat conducting sheets 56 connected to one side of the base 55, the plurality of first heat conducting sheets 56 are arranged along the extension direction of the base 55, and a slot 50a is formed between two adjacent first heat conducting sheets 56. The heat conducting sheet also includes a plurality of second heat conducting sheets 57 connected to the other side of the base 55, the plurality of second heat conducting sheets 57 are arranged on both sides of the base 55 opposite to the plurality of first heat conducting sheets 56, the plurality of second heat conducting sheets 57 are arranged along the extension direction of the base 55, and a slot 50a is also formed between two adjacent second heat conducting sheets 57.

[0047] The first heat conductive sheet 59 and the second heat conductive sheet 57 are configured such that when the heat conductive member 53 wraps the flexible support member 10, the first heat conductive sheet 56 is bent from the outer ring surface 13 to the first support surface 15, and the second heat conductive sheet 57 is turned over the second support surface 17 from the outer ring surface 13 and bent to the inner ring surface 11. In this way, the flexible support member 10 can be covered by the base 55, the first heat conductive sheet 56 and the second heat conductive sheet 57, that is, the flexible support member 10 is wrapped. It should be noted that Figure 8 and Fig. 9 It is a schematic diagram of the structure in which the heat conducting member 50 and the flexible support body 10 are assembled in this structural form.

[0048] For further information, please refer to Figure 7 Based on the structural form of this embodiment, since the base 55 covers the outer ring surface 13, the two ends of the base 55 in its extension direction need to be connected, so the heat conductor 50 can also include two connecting parts, the two connecting parts are respectively connected to the two ends of the base 55 in its extension direction, and the two connecting parts can be detachably connected by bonding or snapping, so as to facilitate the disassembly and assembly of the heat conductor 50 from the outer ring surface 13 of the flexible support body 10. In one embodiment, one connecting part can be formed with a card slot, and the other connecting part can be formed with a buckle that matches the card slot, and the two connecting parts are snapped together by the matching connection of the buckle and the card slot.

[0049] In another embodiment, see Fig.10 The base 55 is annular and arranged around the second support surface 17, and the base 55 covers part of the second support surface 17. When the flexible support body 10 is arranged in annular shape, the second support surface 17 covered by the base 55 is also annular. In this way, when the base 55 is annular, it is convenient for the base 55 to cover the second support surface 17, with a large coverage area and convenient operation.

[0050] The heat conducting sheet 53 includes a plurality of first heat conducting sheets 56 connected to the outside of the base 55, the plurality of first heat conducting sheets 56 are arranged in sequence along the extension direction of the base 55, and a slot 50a is formed between two adjacent first heat conducting sheets 56. The first heat conducting sheets 56 are configured to go over the outer annular surface 13 from the second supporting surface 17 and bend to the first supporting surface 15 when the heat conducting member 50 wraps the flexible support member 10. The heat conducting sheet also includes a plurality of second heat conducting sheets 57 connected to the inside of the base 55, the plurality of second heat conducting sheets 57 are arranged along the extension direction of the base 55, and a slot 50a is formed between two adjacent second heat conducting sheets 57, and the second heat conducting sheets 57 are configured to bend to the inner annular surface 11 from the second supporting surface 17 when the heat conducting member 50 wraps the flexible support member 10. Through the above arrangement, grooves 50a are formed on the opposite sides of the heat conductor 50. With this arrangement, for the flexible support body 10 structure arranged in an annular shape, when the surface areas of the inner annular surface 11 and the outer annular surface 13 are different, the arrangement of the grooves 50a can be utilized to allow the heat conductor 50 to fully stretch its overall structure during the process of wrapping the different surfaces of the flexible support body 10, thereby achieving full coverage and wrapping of the flexible support body 10, and after wrapping, the surface of the heat conductor 50 is smooth and not prone to wrinkles.

[0051] Please continue reading Fig.10 In one structural form, for the slot 50a corresponding to the position of the first heat conducting sheet 56, the slot 50a includes a first slot section 50b and a second slot section 50c that are connected. Specifically, a step-like structure can be formed between the first slot section 50b and the second slot section 50c, so that when the flexible support body 10 is deformed, part of the structure of the flexible support body 10 can extend from the first slot section 50b, so that the heat conducting member 50 can better adapt to the deformation of the flexible support body 10, avoid interference, and ensure the basic support effect of the flexible support body 10.

[0052] The first heat conducting sheet 56 includes a first extension section 561 and a second extension section 563 connected to each other. The first extension section 561 goes over the outer ring surface 13, and the second extension section 563 is bent around the first support surface 15. A first slot section 50b is formed between the first extension sections 561 on two adjacent first heat conducting sheets 56, and a second slot section 50c is formed between the second extension sections 563 on two adjacent first heat conducting sheets 56. The first extension section 561 is in a substantially rectangular structure, while the second extension section 563 is in a substantially isosceles trapezoidal structure, and the longer bottom edge of the second extension section 563 is connected to the first extension section 561, so that a step structure is constructed between the first slot section 50b and the second slot section 50c.

[0053] The above content introduces two forms of the thermal conductive member 50 as a graphene thermal conductive sheet wrapping the flexible support body 10. Furthermore, the distance between two adjacent thermal conductive sheets 53 can be set to increase in the direction away from the substrate 55, that is, the distance between two adjacent first thermal conductive sheets 56 can be set to increase in the direction away from the substrate 55, and the distance between two adjacent second thermal conductive sheets 57 can be set to increase in the direction away from the substrate 55. Under such a setting, the groove area of ​​the groove 50a can be set to increase in the direction away from the substrate 55, so as to further facilitate the flattening of the first thermal conductive sheet 56 and the second thermal conductive sheet 57 of the thermal conductive sheet 53 to avoid wrinkling of the first thermal conductive sheet 56 and the second thermal conductive sheet 57 of the thermal conductive sheet 53 of the thermal conductive member 50.

[0054] The angle between two adjacent heat conducting sheets 53 can range from 15 to 40 degrees, that is, the angle between two adjacent first heat conducting sheets 56 can range from 15 to 40 degrees, and the angle between two adjacent second heat conducting sheets 57 can range from 15 to 40 degrees. When the angle between two adjacent heat conducting sheets 53 of the heat conducting member 50 is small, the gap is too small to be flattened to achieve wrinkle removal, and when the angle between two adjacent heat conducting sheets 53 of the heat conducting member 50 is large, the area of ​​the heat conducting sheet 53 is reduced, thereby causing the contact area between the heat conducting sheet 53 and the cover body 30 to become smaller, affecting the heat conduction effect of the heat conducting sheet 53 on the cover body 30. The angle between the two adjacent heat conducting sheets 53 in the present application can be specifically set to 15 degrees, 20 degrees, 25 degrees, 30 degrees, 35 degrees, 40 degrees or 50 degrees, etc., and the present application does not limit this.

[0055] See Combination Fig.10 In the actual assembly process of the earphone receiver 300, in order to facilitate the maintenance of the ear shell 310 or the earmuff 100 of the earphone receiver 300, the two are configured to be detachably connected. Specifically, one of the shell 320 of the ear shell 310 and the connecting member 70 of the earmuff 100 can be provided with a buckle, and the other can be provided with a slot that cooperates with the buckle, so as to achieve a detachable connection between the two. On this basis, in order to prevent the heat conductive member 50 from interfering with the assembly process of the shell 320 and the connecting member 70, a first avoidance hole 58 for avoiding the buckle or the slot can be opened in the first heat conductive sheet 56 of the heat conductive member 50.
