Description

Technical Field

[0001] This application relates to the field of headphone accessories technology, and more particularly to a headphone case. Background Technology

[0002] Bluetooth earphones are becoming increasingly popular in daily life. Earphone cases, serving as both storage and charging tools, need to stably house the earphones. However, during use, the earphones may become loose inside the case, leading to poor charging contact, affecting charging efficiency and speed, and increasing the frequency of friction between the earphones and the inner wall of the case. Utility Model Content

[0003] This application provides an earphone case that improves the stability of earphones placed inside the earphone case while simplifying its structure.

[0004] This application provides an earphone case, including:

[0005] The housing has a first side surface, on which a contoured groove is formed for storing earphones; and...

[0006] The cover includes a cover body and a flexible abutment layer. The cover body is connected to the box body, and the flexible abutment layer is disposed on one side of the cover body.

[0007] In the case where the earphone case is closed, the cover body is in contact with the first side, the surface of the cover body facing the case is the first surface, and along the direction perpendicular to the first side, the orthographic projection of the flexible abutment layer overlaps with at least a portion of the orthographic projection of the first surface, and the flexible abutment layer abuts against the earphone.

[0008] In some embodiments of this application, along a direction perpendicular to the first side, the percentage of the overlapping area between the orthographic projection of the flexible abutment layer and the orthographic projection of the first surface is S, where S satisfies 1% ≤ S ≤ 100%.

[0009] In some embodiments of this application, S satisfies 30% ≤ S ≤ 70%.

[0010] In some embodiments of this application, the housing has two contoured slots, each for accommodating an earphone. At least a portion of the two contoured slots intersect, such that when the two earphones are stored, at least a portion of their orthographic projections overlap in a direction perpendicular to the first side, thereby reducing the space occupied by the earphones in the earphone case and thus reducing the volume of the earphone case, making it more compact.

[0011] In some embodiments of this application, the two contoured grooves are a first contoured groove and a second contoured groove, respectively. The depth of the first contoured groove is greater than the depth of the second contoured groove. When the two earphones are respectively stored in the two contoured grooves, the earphone in the second contoured groove is located above the earphone in the first contoured groove, and the two earphones abut against each other. In the case of the earphone box in the closed state, the flexible abutting layer abuts against the earphone located in the second contoured groove.

[0012] In some embodiments of this application, the earphone includes an ear hook and a sound-emitting part connected to each other; the contoured groove has a first recess and a second recess that are connected, the groove depth of the first recess is greater than the groove depth of the second recess, the first recess is used to place the sound-emitting part, and the orthographic projection shape of the second recess is arc-shaped, the second recess is used to place the ear hook. The different groove depths of the first recess and the second recess can limit the ear hook and the sound-emitting part, and the arc shape of the first recess can limit the ear hook, thereby making the placement of the sound-emitting part and the ear hook more stable and reducing the shaking of the earphone when placed.

[0013] In some embodiments of this application, the first recesses in the two contoured grooves are spaced apart so that the sound-producing parts of the headphones are spaced apart, reducing friction between the two sound-producing parts and thus affecting the normal sound output of the sound-producing parts. The second recesses of the two contoured grooves are at least partially intersecting so that the ear hooks of the headphones overlap, thereby reducing the space occupied by the headphones in the headphone case and reducing the wear and tear caused by the overlapping placement of the ear hooks.

[0014] In some embodiments of this application, the housing has two contoured slots, each for storing one earphone. The two contoured slots are spaced apart so that when the two earphones are stored, they are arranged alternately, allowing the left and right earphones to be placed separately without interfering with each other, thereby reducing the mutual influence between the two earphones when placed.

[0015] In some embodiments of this application, the hardness of the cover body is greater than the hardness of the flexible abutment layer, and the cover body and the flexible abutment layer are integrally molded by two-color injection molding.

[0016] In some embodiments of this application, the headphone case further includes a first suction member and a second suction member. The first suction member is disposed on the case body, and when the headphone case is closed, the first suction member is located on the side of the case body closer to the lid. The second suction member is disposed on the lid, and when the headphone case is closed, the second suction member is located on the side of the lid closer to the case body. The second suction member and the first suction member are mutually attracted to each other to ensure that the headphone case is tightly sealed when closed, effectively preventing external dust from entering the interior of the headphone case.

[0017] Based on the headphone case in this application embodiment, this embodiment provides a flexible abutment layer on the lid body, so that when the headphone case is closed, the flexible abutment layer can abut against the headphone. This not only reduces the wear and tear on the headphone caused by the flexible abutment layer, but also allows the headphone to be placed stably in the contoured groove, preventing the headphone from shaking in the contoured groove. At the same time, after the headphone case is closed, the surface of the flexible abutment layer facing the headphone can be used to abut against the headphone, thereby reducing the probability of the position of the flexible abutment layer and the position of the headphone being misaligned. This eliminates the need for detailed point-to-point alignment of the headphone and the flexible abutment layer during the assembly of the headphone case, thereby simplifying the structure of the headphone case and reducing the manufacturing and assembly difficulty of the headphone case. In other words, this application embodiment only needs to cover at least part of the first surface with a flexible abutment layer. On the basis of simplifying the structure of the headphone case, it can also make the open-back headphone placed inside the headphone case more stable and the placement position more accurate.

[0031] To more clearly illustrate the technical solutions in the embodiments of this application or related technologies, a clear and complete description will be provided below with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0032] Bluetooth earbuds, particularly open-back models, consist of the earbud body and ear hooks. The charging case, used for storing and charging these earbuds, needs to hold them securely inside. However, during use, the earbuds may become loose within the case, leading to poor charging contact, affecting charging efficiency and speed. It also increases friction between the earbuds and the case's inner wall, causing noise and potentially shortening the earbuds' lifespan. Furthermore, if the earbuds are misaligned within the case, the case may not close properly.

[0033] For the above situation, please refer to Figures 1-3 This application proposes an earphone case 100, including a case body 10 and a cover 20. The earphone case 100 can be used to store open-back earphones 200 and to charge the open-back earphones 200. The case body 10 has a first side surface 14 for contacting the cover 20. A contoured groove 11 is formed on the first side surface 14 for storing the earphones 200. There can be two contoured grooves 11, which are used to store the left and right earphones 200 respectively.

[0034] The cover 20 includes a cover body 21 and a flexible abutment layer 22. The cover body 21 is connected to the box body 10, and the flexible abutment layer 22 is disposed on one side of the cover body 21. When the headphone box 100 is closed, the cover body 21 contacts the first side 14. The surface of the cover body 21 facing the box body 10 is the first surface 211. Along the direction perpendicular to the first side 14, the orthographic projection of the flexible abutment layer 22 overlaps with at least a portion of the orthographic projection of the first surface 211, and the flexible abutment layer 22 abuts against the headphone 200.

[0035] It is understood that by providing a flexible abutment layer 22 on the cover body 21, the flexible abutment layer 22 can abut against the earphone 200 when the earphone case 100 is closed. This can stably restrict the loosening of the earphone 200, prevent the earphone 200 from lifting up and rubbing against the inner wall of the earphone case 100, and prevent the earphone 200 from shaking in the contour groove 11. This not only reduces the wear of the flexible abutment layer 22 on the earphone 200, but also allows the earphone 200 to be stably placed in the contour groove 11. Meanwhile, after the headphone case 100 is closed, the surface of the flexible abutment layer 22 facing the headphone 200 can be used to abut against the headphone 200, thereby reducing the probability of the position of the flexible abutment layer 22 intersecting with the position of the headphone 200. This means that during the assembly of the headphone case 100, it is not necessary to perform detailed point-to-point alignment of the headphone 200 and the flexible abutment layer 22. In other words, the specific installation position of the flexible abutment layer 22 on the first surface 211 is not unique. This simplifies the structure of the headphone case 100 and reduces the manufacturing and assembly difficulty of the headphone case 100. That is to say, in this embodiment, the flexible abutment layer 22 only needs to be covered on at least part of the first surface 211. On the basis of simplifying the structure of the headphone case 100, the open-back headphone 200 inside the headphone case 100 can be placed more stably and in a more accurate position.

[0036] It should be noted that the cover body 21 and the housing 10 together form a closed receiving cavity, in which the open-back earphone 200 is housed. The connection between the cover body 21 and the housing 10 can be a rotatable connection or a detachable connection, such as a snap-fit, magnetic, or sliding connection. For example, ... Figure 2 As shown, the cover 20 is rotatably connected to the housing 10 via a pivot 12, and the housing 10 is provided with a charging port 13. The charging port 13 is used to electrically connect to a charging plug to charge the earphone case 100 and the earphones 200 inside. The charging port 13 is located on the side of the housing 10 near the pivot 12, thereby reducing interference from the charging cable to the rotation and opening of the cover 20. The first surface 211 of the cover body 21 can be a plane, a curved surface, or an arc surface; no specific limitation is made here.

[0037] In some embodiments of this application, the percentage of the overlapping area between the orthographic projection of the flexible abutment layer 22 and the orthographic projection of the first surface 211 along a direction perpendicular to the first side 14 is S, where S satisfies 1% ≤ S ≤ 100%.

[0038] Specifically, at least a portion of the first surface 211 of the cover body 21 is covered with a flexible abutment layer 22. The further specific value range of S can also be within the range of 5% to 95%, 10% to 90%, 15% to 85%, 20% to 80%, 25% to 75%, 30% to 70%, 35% to 65%, and 40% to 60%. The value range of S can be selected according to the actual situation, and no specific limitation is made in this embodiment.

[0039] Preferably, S satisfies 60% ≤ S ≤ 100%, so that the flexible abutment layer 22 can cover as large an area as possible on the first surface 211. This further increases the probability that the flexible abutment layer 22 abuts against the earphone 200 when the earphone case 100 is closed, eliminating the need for point-to-point alignment of the earphone 200 and the flexible abutment layer 22 during assembly. This simplifies the structure of the earphone case 100 and reduces the manufacturing and assembly difficulty. For example, when S is 100%, the entire first surface 211 is covered by the flexible abutment layer 22. Therefore, it is not necessary to specifically set the flexible abutment layer 22 in the earphone case 100 for the specific placement position of the earphone 200, which further reduces the manufacturing and assembly difficulty of the earphone case 100.

[0040] In some embodiments, the hardness of the cover body 21 is greater than the hardness of the flexible abutment layer 22. For example, both the housing 10 and the cover body 21 can be made of rigid colloid, which improves the structural strength of the housing 10 and the cover body 21, so that the housing 10 and the cover body 21 can provide better protection for the earphone 200. The flexible abutment layer 22 can be made of soft colloid, which can apply stable pressure to the earphone 200 and reduce friction between the flexible abutment layer 22 and the earphone 200 to a certain extent. During the closing process, the material of the soft colloid provides a certain buffer when the flexible abutment layer 22 abuts against the earphone 200, avoiding damage to the earphone 200. Specifically, the rigid colloid is rigid rubber or engineering plastic with a hardness range of 50 Shore D to 90 Shore D, and the soft colloid is elastic rubber or elastic plastic with a hardness range of 10 Shore A to 50 Shore A. For example, the soft colloid can be silicone, and the hardness of silicone can be adjusted and customized according to requirements.

[0041] The cover body 21 and the flexible contact layer 22 can be integrally molded using a two-color injection molding process. Two-color injection molding refers to injecting two different materials into the same mold, thereby realizing the molding process of the injection-molded parts formed by two materials. The two materials have different hardness, thereby improving the assembly performance of the product. At the same time, the two materials can also have different colors, thereby improving the aesthetics of the product.

[0042] Please see Figure 1In some embodiments of this application, the earphone case 100 further includes a first suction member 31 and a second suction member 32. The first suction member 31 is disposed on the case body 10. When the earphone case 100 is closed, the first suction member 31 is located on the side of the case body 10 closer to the cover 20. The second suction member 32 is disposed on the cover 20. When the earphone case 100 is closed, the second suction member 32 is located on the side of the cover 20 closer to the case body 10, and the second suction member 32 and the first suction member 31 are mutually attracted to each other.

[0043] Specifically, the first adsorption member 31 and the second adsorption member 32 can provide adsorption force for the case 10 and the cover 20. When the case 10 and the cover 20 are in the closed state, the first adsorption member 31 and the second adsorption member 32 adsorb each other to ensure that the earphone case 100 is tightly sealed when closed, effectively preventing external dust from entering the interior of the earphone case 100.

[0044] In some embodiments of this application, the headphone case 100 further includes a third suction member (not shown in the figure). The third suction member is disposed within the contour groove 11 and is used to suction the headphones 200. It is understood that the placement of the third suction member can make the headphones 200 more stable within the headphone case 100, reducing the shaking of the headphones 200 within the contour groove 11, thereby reducing the friction frequency between the headphones 200 and the inner wall of the contour groove 11. A fourth suction member can be correspondingly disposed on the headphones 200 so that the third and fourth suction members can attract each other, thereby further improving the stability of the headphones 200 within the contour groove 11.

[0045] In some embodiments of this application, such as Figure 4 As shown, the inner walls of the contour groove 11 are all curved surfaces that fit the outer surface of the earphone 200. This ensures that when the earphone 200 is placed in the contour groove 11, the surface of the earphone 200 is in contact with the curved inner wall of the contour groove 11, reducing the friction between the contour groove 11 and the earphone 200, thereby reducing the wear of the inner wall of the contour groove 11 on the earphone 200.

[0046] In some embodiments of this application, the housing 10 has two contoured grooves 11, each contoured groove 11 for accommodating one earphone 200. The two contoured grooves 11 are spaced apart so that when the two earphones 200 are stored, the two earphones 200 are arranged alternately (not shown in the figure). That is, when stored, the left and right earphones 200 are placed separately and do not interfere with each other, thereby reducing the mutual influence between the two earphones 200 when they are placed.

[0047] Alternatively, please see Figure 1 and Figure 4In some embodiments of this application, the housing 10 has two contoured grooves 11, each for accommodating one earphone 200. At least a portion of the two contoured grooves 11 intersects, such that when the two earphones 200 are stored, at least a portion of their orthographic projections overlap in a direction perpendicular to the first side 14. It is readily understood that when stored, at least a portion of the left and right earphones 200 are placed vertically overlapping to reduce the space occupied by the earphones 200 in the earphone case 100, thereby reducing the volume of the earphone case 100 and making it more compact.

[0048] Further reading is available upon request. Figure 1 and Figure 4 In some embodiments of this application, the two contoured grooves 11 are respectively the first contoured groove 111 and the second contoured groove 112. The groove depth of the first contoured groove 111 is greater than the groove depth of the second contoured groove 112. When the two earphones 200 are respectively housed in the two contoured grooves 11, the earphone 200 in the second contoured groove 112 is located above the earphone 200 in the first contoured groove 111, and the two earphones 200 abut against each other.

[0049] Specifically, taking the earphone 200 placed in the first contoured groove 111 as the left earphone 201 and the earphone 200 placed in the second contoured groove 112 as the right earphone 202 as an example, since the groove depth of the first contoured groove 111 is relatively large, when the two earphones 200 are stored, at least part of the left earphone 201 is located below the right earphone 202. In the closed state of the earphone case 100, the flexible abutment layer 22 abuts against the earphone 200 located in the second contoured groove 112. That is to say, the flexible abutment layer 22 abuts against the right earphone 202 located above. Therefore, there is an abutment force between the flexible abutment layer 22 and the right earphone 202. Under the action of the abutment force and gravity, the right earphone 202 presses on the left earphone 201. Therefore, at least part of the left earphone 201 and the right earphone 202 are in an abutment state.

[0050] like Figure 3 As shown, the earphone 200 includes an ear hook 40 and a sound-emitting part 50 connected to each other. The sound-emitting part 50 is worn in the user's concha, and the ear hook 40 extends along the periphery of the user's auricle to hang on the user's ear, thereby wearing the earphone 200 body on the user's ear. In some embodiments of this application, such as Figure 5As shown, the contoured groove 11 has a first recess 113 and a second recess 114 that are connected. The first recess 113 is used to place the sound-emitting part 50, and the second recess 114 is used to place the ear hook 40. Since the sound-emitting part 50 is relatively large and requires a large storage space, the groove depth of the first recess 113 is greater than the groove depth of the second recess 114. This ensures that when the earphone 200 is placed in the contoured groove 11, the sound-emitting part 50 can be located in the deeper first recess 113. At the same time, since the ear hook 40 extends along the periphery of the user's auricle and its overall shape is arc-shaped, the orthographic projection shape of the second recess 114 is arc-shaped, thus making the overall shape of the second recess 114 fit the shape of the ear hook 40. In addition, the inner wall of the second recess 114 is a curved surface that fits the shape of the ear hook 40.

[0051] Specifically, the different groove depths of the first recess 113 and the second recess 114 can limit the ear hook 40 and the sound-emitting part 50, and the arc shape of the first recess 113 can limit the ear hook 40, thereby making the placement of the sound-emitting part 50 and the ear hook 40 more stable and reducing the shaking of the headphones 200 when placed.

[0052] It should be noted that the groove depth of the first recess 113 is different from that of the second recess 114, that is, there is a height difference between the first recess 113 and the second recess 114. At the position where the first recess 113 and the second recess 114 have a height difference, a slope or arc surface can be provided for guidance, so that the connection between the first recess 113 and the second recess 114 is smoother, and the wear caused by the height difference between the first recess 113 and the second recess 114 to the placement of the earphone 200 is reduced.

[0053] Further, please see Figures 4-5 In some embodiments of this application, the first recesses 113 in the two contoured grooves 11 are spaced apart, and at least part of the second recesses 114 in the two contoured grooves 11 intersect. It is understood that the sound-emitting part 50 of the earphone 200 is provided with acoustic components and circuit components. Therefore, when both earphones 200 are placed in the contoured grooves 11, the sound-emitting parts 50 of the two earphones 200 are spaced apart, thereby reducing friction between the two sound-emitting parts 50 and thus affecting the normal sound output of the sound-emitting part 50. The ear hooks 40 of the earphones 200 are used to wrap around and hang on the user's auricle. The ear hooks 40 are usually made of silicone or plastic. Therefore, when both earphones 200 are placed in the contoured grooves 11, the ear hooks 40 of the two earphones 200 partially overlap, thereby reducing the space occupied by the earphones 200 in the earphone case 100 and reducing the wear caused by the overlapping placement of the ear hooks 40.
