Description

Technical Field

[0001] This utility model relates to the field of audio equipment technology, and in particular to an earphone charging case and earphone kit. Background Technology

[0002] The difference between over-ear open-back headphones and ordinary open-back headphones is that the two earpieces are connected by a headband. Due to manufacturing errors or deformation of the headband, the two earpieces may inevitably be asymmetrical. When both earpieces are placed in the charging case, the charging terminals on the earpieces may not be able to contact the charging pins on the charging case due to the influence of the headband, resulting in the inability to charge. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an earphone charging case that improves the problem of poor contact between the charging terminals on the earphone unit and the charging pins of the earphone charging case.

[0004] This utility model also proposes an earphone kit with the aforementioned earphone charging case.

[0005] According to a first aspect of the present invention, an earphone charging case includes: a case body having an earphone slot and a mounting opening penetrating the wall of the earphone slot; and a charging pin assembly movably disposed in the mounting opening, the charging pin assembly being configured to move along the depth direction of the mounting opening, wherein the charging pin assembly includes a mounting block at least partially disposed in the mounting opening, a charging pin disposed on the mounting block, and a first magnetic member disposed on the mounting block, the charging pin extending into or facing the earphone slot.

[0006] The earphone charging case according to the embodiment of this utility model has at least the following beneficial effects:

[0007] In this earphone charging case, the earphone unit has a second magnetic component inside. When the earphone unit is placed in the earphone slot, the second magnetic component attracts the first magnetic component. At this time, the charging pin assembly moves closer to the earphone unit along the depth direction of the mounting opening, causing the charging pin to contact the charging terminal on the earphone unit, thus allowing the earphone charging case to charge the earphone unit. It is understood that, for the aforementioned earphones, due to the presence of the headband, deformation of the headband, or manufacturing errors, the two earphone units may be asymmetrical. In this case, when the earphone unit is placed in the earphone slot, the force of the headband may prevent the earphone unit from fitting snugly against the slot wall. In other words, the earphone unit may not fully sink into the earphone slot (the earphone unit tilts), resulting in a gap between the charging terminal and the charging pin, preventing charging of the earphone unit. When this occurs, the second magnetic component inside the earphone unit attracts the first magnetic component on the charging pin assembly, causing the charging pin assembly to move closer to the earphone unit along the depth direction of the mounting opening, thus causing the charging pin to contact the charging terminal on the earphone unit, allowing the earphone charging case to charge the earphone unit. Of course, when the first magnetic component and the second magnetic component attract each other, the attraction force exerted by the first magnetic component on the entire earphone unit can counteract at least part of the force exerted by the headband on the earphone unit, so that the earphone unit is further aligned, thereby reducing the risk that the charging terminal and the charging pin cannot make contact.

[0008] According to some embodiments of the present invention, the charging pin assembly includes two charging pins, which are spaced apart and arranged side by side on the mounting block. The arrangement direction of the two charging pins is parallel to the depth direction of the mounting opening, and the first magnetic member is located between the two charging pins.

[0009] According to some embodiments of this utility model, a plane perpendicular to the depth direction of the mounting opening is defined as a reference plane, and the projection of the first magnetic member on the reference plane is covered by the projection of the mounting opening on the reference plane.

[0010] According to some embodiments of the present invention, the mounting block is provided with a positioning groove, and the first magnetic suction member is disposed in the positioning groove.

[0011] According to some embodiments of the present invention, the positioning groove is formed on the side of the mounting block away from the headphone slot.

[0012] According to some embodiments of the present invention, the mounting block has a guide portion and a travel limiting portion connected to the guide portion. The guide portion passes through the mounting opening, and the travel limiting portion is located on the side of the mounting opening away from the headphone slot. The travel limiting portion is matched with the edge of the mounting opening away from the headphone slot.

[0013] According to some embodiments of the present invention, the mounting block is provided with a mounting hole, the mounting hole is connected to the earphone slot, and one end of the mounting hole is positioned facing the earphone slot, and the charging pin passes through the mounting hole.

[0014] According to some embodiments of the present invention, the earphone charging case further includes a motherboard disposed inside the case, and the charging pin is connected to the motherboard via a wire.

[0015] According to a second aspect of the present invention, an earphone kit includes an earphone charging case as described above; earphones, each earphone including an earphone unit, the earphone unit having a second magnetic member and a charging terminal, the earphone unit being configured to be placed in the earphone slot, and the second magnetic member magnetically engaging with the first magnetic member, so that the charging pin contacts and engages with the charging terminal.

[0016] According to some embodiments of the present invention, the headphones further include a headband, the headphones have two earphone units, and the two ends of the headband are respectively connected to the two earphone units;

[0017] The housing has two earphone slots, and there are two charging pin assemblies. The two charging pin assemblies are arranged corresponding to the two earphone slots, and the two earphone units can be placed in the two earphone slots respectively.

[0018] The headphone kit according to the embodiment of this utility model has at least the following beneficial effects:

[0019] In this earphone kit, the earphone unit has a second magnetic component inside. When the earphone unit is placed in the earphone slot, the second magnetic component attracts the first magnetic component. At this time, the charging pin assembly moves closer to the earphone unit along the depth direction of the mounting opening, causing the charging pin to contact the charging terminal on the earphone unit, thus allowing the earphone charging case to charge the earphone unit. It is understood that, for the aforementioned earphones, due to the presence of the headband, deformation of the headband or manufacturing errors may cause the two earphone units to be asymmetrical. In this case, when the earphone unit is placed in the earphone slot, the force of the headband may prevent the earphone unit from fitting snugly against the slot wall. In other words, the earphone unit may not fully sink into the earphone slot (the earphone unit tilts), resulting in a gap between the charging terminal and the charging pin, preventing charging of the earphone unit. When this occurs, the second magnetic component inside the earphone unit attracts the first magnetic component on the charging pin assembly, causing the charging pin assembly to move closer to the earphone unit along the depth direction of the mounting opening, thus causing the charging pin to contact the charging terminal on the earphone unit, allowing the earphone charging case to charge the earphone unit. Of course, when the first magnetic component and the second magnetic component attract each other, the attraction force exerted by the first magnetic component on the entire earphone unit can counteract at least part of the force exerted by the headband on the earphone unit, so that the earphone unit is further aligned, thereby reducing the risk that the charging terminal and the charging pin cannot make contact.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] Figure 1An earphone 100 is shown, which is a type of over-ear headphone, comprising two earphone units 110 and a headband 120. The two earphone units 110 are respectively disposed at both ends of the headband 120. It should be noted that the earphone units 110 are capable of playing sound, and the headband 120 connects the two earphone units 110. Furthermore, the earphone 100 can be an open-back headphone, and can be configured with call noise reduction and / or artificial intelligence noise reduction functions. It can also be configured with stereo surround sound and other functions.

[0035] like Figure 2 As shown, an embodiment of the present invention provides an earphone charging case 200, which can charge the earphone unit 110 placed inside the earphone charging case 200. Specifically, the earphone unit 110 is provided with a charging terminal, and the earphone charging case 200 is provided with a charging pin 222. When the charging pin 222 contacts the charging terminal, the earphone charging case 200 can charge the earphone unit 110.

[0036] like Figure 3 As shown, the earphone charging case 200 includes a case body 210 and a charging pin assembly 220.

[0037] Combination Figure 3 and Figure 4 The housing 210 has an earphone slot 211 and an installation port 212 that passes through the wall of the earphone slot 211.

[0038] Specifically, the housing 210 is a hollow structure with an inner cavity. An earphone slot 211 is provided on its upper side, and a mounting opening 212 extends from the wall of the earphone slot 211 into the inner cavity of the housing 210, connecting the inner cavity of the housing 210 with the earphone slot 211. The earphone slot 211 is used to house the earphone unit 110.

[0039] The charging pin assembly 220 is movably disposed in the mounting port 212 and is configured to move along the depth direction of the mounting port 212.

[0040] Specifically, the charging pin assembly 220 is a movable component, with a portion of its structure disposed within the mounting opening 212. Furthermore, the charging pin assembly 220 is capable of moving along the depth direction of the mounting opening 212. It should be noted that the mounting opening 212 is located on the bottom wall of the earphone slot 211, and the depth direction of the mounting opening 212 is vertical, allowing the charging pin assembly 220 to move vertically.

[0041] like Figures 3 to 6As shown, the charging pin assembly 220 further includes a mounting block 221, a charging pin 222, and a first magnetic member 223. At least a portion of the mounting block 221 is disposed in the mounting opening 212, and the mounting block 221 is movable along the depth direction of the mounting opening 212. The charging pin 222 is disposed on the mounting block 221, extending into or towards the earphone slot 211. The first magnetic member 223 is disposed on the mounting block 221. It is understood that the mounting block 221, the charging pin 222, and the first magnetic member 223 are connected together and can move together along the depth direction of the mounting opening 212.

[0042] It should be noted that the earphone unit 110 has a second magnetic component inside. When the earphone unit 110 is placed in the earphone slot 211, the second magnetic component attracts the first magnetic component 223. At this time, the charging pin assembly 220 moves closer to the earphone unit 110 along the depth direction of the mounting opening 212, so that the charging pin 222 contacts the charging terminal on the earphone unit 110, allowing the earphone charging case 200 to charge the earphone unit 110. Both the first magnetic component 223 and the second magnetic component are magnets.

[0043] Understandably, for the aforementioned earphone 100, due to the presence of the headband 120, deformation of the headband 120 or manufacturing errors may cause the two earphone units 110 to be asymmetrical. In this case, when the earphone unit 110 is placed into the earphone slot 211, under the force of the headband 120, the earphone unit 110 may not be able to fit snugly against the wall of the earphone slot 211. In other words, the earphone unit 110 may not be completely submerged in the earphone slot 211 (the earphone unit 110 tilts), resulting in a gap between the charging terminal and the charging pin 222, thus preventing the earphone unit 110 from being charged. When this occurs, the second magnetic component inside the earphone unit 110 will attract the first magnetic component 223 on the charging pin assembly 220, thereby causing the charging pin assembly 220 to move closer to the earphone unit 110 along the depth direction of the mounting opening 212, so that the charging pin 222 contacts the charging terminal on the earphone unit 110, allowing the earphone charging case 200 to charge the earphone unit 110. Of course, when the first magnetic member 223 and the second magnetic member attract each other, the attraction force exerted by the first magnetic member 223 on the entire earphone unit 110 can offset at least part of the force exerted by the headband 120 on the earphone unit 110, so that the earphone unit 110 is further aligned, thereby reducing the risk that the charging terminal and the charging pin 222 cannot make contact.

[0044] It should be noted that a third magnetic component (magnet) can be provided inside the housing 210. This third magnetic component can magnetically engage with the second magnetic component inside the earphone unit 110, thereby ensuring that the earphone unit 110 is placed as correctly as possible within the earphone slot 211. When the magnetic attraction between the third and second magnetic components is insufficient to eliminate the earphone unit 110's inability to be placed correctly within the earphone slot 211 due to the headband 120, the second magnetic component inside the earphone unit 110 will attract the first magnetic component 223 on the charging pin assembly 220. This causes the charging pin assembly 220 to move closer to the earphone unit 110 along the depth direction of the mounting opening 212, thereby bringing the charging pin 222 into contact with the charging terminal on the earphone unit 110.

[0045] like Figure 3 As shown, it should be noted that the housing 210 has two earphone slots 211 and two charging pin assemblies 220. The two charging pin assemblies 220 are arranged corresponding to the two earphone slots 211. The two earphone units 110 can be placed in the two earphone slots 211 respectively, so as to contact the two charging pin assemblies 220 respectively.

[0046] like Figure 4 As shown, the charging pin assembly 220 further includes two charging pins 222, which are spaced apart and arranged side by side on the mounting block 221. The arrangement direction of the two charging pins 222 is parallel to the depth direction of the mounting opening 212, and the first magnetic member 223 is located between the two charging pins 222.

[0047] It is understood that of the two charging pins 222 in the charging pin assembly 220, one is a positive charging pin and the other is a negative charging pin; the earphone unit 110 has two charging terminals, one of which is a positive charging terminal and the other is a negative charging terminal. When the earphone unit 110 is placed in the earphone charging case 200, the two charging pins 222 contact the two charging terminals respectively, thereby charging the earphone unit 110. The first magnetic member 223 is located between the two charging pins 222, and the line of action of the magnetic attraction force passes through the geometric center of the two charging pins 222. Thus, when the first magnetic member 223 is attracted by the second magnetic member of the earphone unit 110, the force on the two charging pins 222 will be more balanced, reducing the risk of the charging pins 222 tilting.

[0048] like Figure 6 As shown, the mounting block 221 has a mounting hole 2214, which communicates with the earphone slot 211, with one end of the mounting hole 2214 facing the earphone slot 211. The charging pin 222 passes through the mounting hole 2214. The charging pin 222 can be fixed to the mounting block 221 with adhesive.

[0049] Specifically, the mounting block 221 is provided with two mounting holes 2214, the arrangement direction of the two mounting holes 2214 is parallel to the depth direction of the mounting opening 212, and the two charging pins 222 are respectively inserted into the two mounting holes 2214.

[0050] like Figure 3 As shown, further, a plane perpendicular to the depth direction of the mounting opening 212 is defined as a reference plane, and the projection of the first magnetic member 223 on the reference plane is covered by the projection of the mounting opening 212 on the reference plane.

[0051] It is understandable that the first magnetic component 223 is located directly below the mounting port 212. Therefore, when the first magnetic component 223 is attracted by the second magnetic component of the earphone unit 110, the movement path of the first magnetic component 223 is more parallel to the depth direction of the mounting port 212, which can reduce the problem of sliding and jamming caused by excessive force on one side of the charging pin assembly 220.

[0052] Furthermore, the mounting block 221 is provided with a positioning groove 2213, and the first magnetic suction member 223 is disposed in the positioning groove 2213. The positioning groove 2213 is used to provide an installation position for the first magnetic suction member 223 and can improve the installation accuracy of the first magnetic suction member 223. The first magnetic suction member 223 can be fixed in the positioning groove 2213 with the help of glue.

[0053] Furthermore, the positioning groove 2213 is formed on the side of the mounting block 221 away from the headphone slot 211. In this way, the first magnetic member 223 is also located on the side of the mounting block 221 away from the headphone slot 211, which can prevent the first magnetic member 223 from being exposed.

[0054] like Figure 4 As shown, in some embodiments, the mounting block 221 has a guide portion 2211 and a travel limiting portion 2212 connected to the guide portion 2211. The guide portion 2211 passes through the mounting opening 212, and the travel limiting portion 2212 is located on the side of the mounting opening 212 away from the headphone slot 211. The travel limiting portion 2212 is matched with the edge of the end of the mounting opening 212 away from the headphone slot 211.

[0055] Understandably, the sidewall of the mounting port 212 can provide guidance for the guide portion 2211, constrain radial offset, and improve the movement accuracy of the charging pin assembly 220; the edge of the end of the mounting port 212 away from the earphone slot 211 is used to limit the maximum displacement of the travel limit portion 2212 towards the earphone slot 211, thereby limiting the maximum displacement of the charging pin assembly 220 towards the earphone slot 211 and preventing the charging pin assembly 220 from coming out of the inner cavity of the housing 210 through the mounting port 212.

[0056] Furthermore, a boss 213 is provided on the edge of the mounting port 212 away from the headphone slot 211. The boss 213 is disposed opposite to the travel limit part 2212. The boss 213 can limit the maximum displacement of the travel limit part 2212 when it moves toward the headphone slot 211.

[0057] Furthermore, the inner cavity of the housing 210 is also provided with a support member 230, which supports the side of the mounting block 221 away from the earphone slot 211. When the support member 230 contacts the mounting block 221, there is a gap between the travel limiting part 2212 and the inner edge of the mounting opening 212. This gap is the maximum displacement of the charging pin assembly 220. The support member 230 can be an elastic support member, such as elastic rubber, which can provide a buffering rebound force and reduce the damage caused by the charging pin assembly 220 hitting the support member 230 hard after the first magnetic member 223 loses the attraction of the second magnetic member.

[0058] It should be noted that the earphone charging case 200 also includes a motherboard disposed inside the case body 210, and the charging pin 222 is connected to the motherboard via a wire. The motherboard is also electrically connected to a battery disposed inside the case body 210, and the battery can supply power to the earphone units 110 via the charging pin 222.

[0059] Understandably, the charging pin 222 is connected to the motherboard via a wire, and the length of the wire is designed to match the maximum stroke of the charging pin assembly 220.

[0060] This utility model also provides an earphone kit, including: the earphone charging case 200 of the above embodiment, and the earphone 100 of the above embodiment. The earphone unit 110 is configured to be placed in the earphone slot 211, and the second magnetic member and the first magnetic member 223 are magnetically attracted to each other so that the charging pin 222 contacts and engages with the charging terminal.

[0061] Specifically, the housing 210 has two earphone slots 211 and two charging pin assemblies 220. The two charging pin assemblies 220 are arranged corresponding to the two earphone slots 211, and the two earphone units 110 can be placed in the two earphone slots 211 respectively.

[0062] It should be noted that the upper side of the housing 210 is also provided with a headband clearance channel 214 that communicates with the headphone slot 211. The headband clearance channel 214 allows the headband 120 to pass through. Thus, when the two earphone units 110 are placed in the two headphone slots 211 respectively, the headband 120 extends out through the headband clearance channel 214.

[0063] In the earphone kit of this utility model, the earphone unit 110 is provided with a second magnetic component inside. When the earphone unit 110 is placed in the earphone slot 211, the second magnetic component and the first magnetic component 223 attract each other. At this time, the charging pin assembly 220 will move closer to the earphone unit 110 along the depth direction of the mounting port 212, so that the charging pin 222 contacts the charging terminal on the earphone unit 110, so that the earphone charging case 200 charges the earphone unit 110. Understandably, for the aforementioned earphone 100, due to the presence of the headband 120, deformation of the headband 120 or manufacturing errors may cause the two earphone units 110 to be asymmetrical. In this case, when the earphone unit 110 is placed into the earphone slot 211, under the force of the headband 120, the earphone unit 110 may not be able to fit snugly against the wall of the earphone slot 211. In other words, the earphone unit 110 may not be completely submerged in the earphone slot 211 (the earphone unit 110 tilts), resulting in a gap between the charging terminal and the charging pin 222, thus preventing the earphone unit 110 from being charged. When this occurs, the second magnetic component inside the earphone unit 110 will attract the first magnetic component 223 on the charging pin assembly 220, thereby causing the charging pin assembly 220 to move closer to the earphone unit 110 along the depth direction of the mounting opening 212, so that the charging pin 222 contacts the charging terminal on the earphone unit 110, allowing the earphone charging case 200 to charge the earphone unit 110. Of course, when the first magnetic member 223 and the second magnetic member attract each other, the attraction force exerted by the first magnetic member 223 on the entire earphone unit 110 can offset at least part of the force exerted by the headband 120 on the earphone unit 110, so that the earphone unit 110 is further aligned, thereby reducing the risk that the charging terminal and the charging pin 222 cannot make contact.
