[0004] To solve the above-mentioned technical problems, one technical solution adopted in this application is to provide an earphone assembly, which includes earphones and a charging case; the earphones include a core housing and a speaker disposed within the core housing; the charging case includes a tray with a receiving groove for accommodating the core housing; wherein the core housing includes an inner side and a patterned portion disposed on the inner side, the patterned portion being flush with or protruding from the inner side, and when the core housing is accommodated in the receiving groove, the inner side faces the bottom wall of the receiving groove, and the patterned portion is spaced apart from the bottom wall of the receiving groove.

[0005] In some embodiments, the patterned portion and the bottom wall of the receiving groove are maintained at a distance in a non-contact manner.

[0006] In some embodiments, the gap between the patterned portion and the bottom wall is between 0.1 mm and 0.3 mm.

[0007] In some embodiments, the mechanism housing has a free end and a connecting end disposed opposite to each other, and the earphone further includes an adapter housing and an elastic hook portion. One end of the adapter housing is connected to the connecting end, and the other end of the adapter housing is connected to the elastic hook portion. When the mechanism housing is accommodated in the receiving groove, the free end and the adapter housing simultaneously contact the receiving groove, so that the pattern portion is suspended relative to the bottom wall.

[0008] In some embodiments, the radial dimension of the adapter housing gradually decreases in the direction away from the main housing.

[0009] In some embodiments, the minimum distance between the contact area formed by the free end and the receiving groove and the patterned portion is not less than 4 mm.

[0010] In some embodiments, the movement housing includes an outer side disposed opposite to the inner side, and an upper side and a lower side connecting the free end and the connecting end, the upper side and the lower side being disposed opposite to each other; at least a portion of the upper side and at least a portion of the lower side respectively contact the groove wall of the receiving groove.

[0011] The minimum distance between the contact area formed by the upper side and the receiving groove and the pattern part is not less than 1.5 mm, and the minimum distance between the contact area formed by the lower side and the receiving groove and the pattern part is not less than 1.5 mm.

[0012] In some embodiments, the minimum distance between the contact area formed by the adapter housing and the receiving groove and the patterned portion is not less than 10 mm.

[0013] In some embodiments, the movement housing includes an outer side disposed opposite to the inner side, and the thickness of the patterned portion in the thickness direction of the movement housing is less than 0.05 mm, the thickness direction being the interval direction between the inner side and the outer side.

[0015] In some embodiments, the distance between the inner side surface and the bottom wall gradually decreases in the direction away from the patterned portion.

[0016] In some embodiments, the charging case further includes a flexible support pad disposed on the bottom wall, the flexible support pad having a lower hardness than the tray, and the patterned portion contacting the flexible support pad when the core housing is placed in the receiving groove.

[0017] In some embodiments, at least one sound outlet is provided on the inner side, and the sound generated by the speaker is transmitted to the outside of the earphone through the sound outlet. The patterned portion is disposed around at least part of the periphery of the sound outlet.

[0018] In some embodiments, the loudspeaker includes a main loudspeaker and an auxiliary loudspeaker, and the sound outlet includes a first sound outlet corresponding to the main loudspeaker and a second sound outlet corresponding to the auxiliary loudspeaker. The first sound outlet is semi-enclosed and surrounds the periphery of the second sound outlet. The patterned portion is surrounded by the periphery of the second sound outlet and is located between the second sound outlet and the first sound outlet.

[0019] The beneficial effects of this application are: the patterned part on the earphone is set to maintain a gap between itself and the bottom wall of the receiving slot in the charging case, so that when the earphone is placed in the charging case, the patterned part on the earphone housing will not come into contact with the bottom wall of the receiving slot. This reduces the wear and tear on the patterned part on the bottom wall of the receiving slot during repeated earphone removal and placement, thus protecting the integrity of the patterned part and ensuring the user experience.

[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of 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.

[0034] The reference to "embodiment" in this application means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0035] The following is an exemplary description of the headphone assembly in an embodiment of the headphone assembly.

[0036] like Figure 1 As shown, the earphone assembly 1 may include earphones 10 and charging case 20.

[0037] The headphones 10 are audio converters capable of receiving electrical signals from a media player or receiver and converting them into sound waves that can be heard by the user. In some embodiments, the headphones 10 may be open-back headphones, such as ear-hook headphones or clip-on headphones.

[0038] In some embodiments, such as Figure 2 as well as Figure 3 As shown, the headphones 10 may include a housing 110 and a speaker 120 disposed within the housing 110. The speaker 120 is a sound playback device that can convert electrical signals into sound signals (also referred to as "sound waves" or "sound signals") and transmit them to the wearer's ear.

[0039] The charging case 20 is a device that can be used with the earphones 10 and charge the earphones 10. Specifically, the charging case 20 is compatible with the earphones 10. The earphones 10 can be placed in the charging case 20 when the battery is low or when they are not in use. The charging case 20 can accommodate the corresponding earphones 10 and charge the earphones 10.

[0040] In some embodiments, such as Figure 1As shown, the charging case 20 may include a tray 210, which may be provided with a receiving groove 211 for accommodating the core housing 110. The shape of the receiving groove 211 and the core housing 110 may be matched so that when the earphone 10 is placed in the charging case 20, the receiving groove 211 can limit the core housing 110, thereby making it difficult for the core housing 110 to move within the receiving groove 211.

[0041] Among them, such as Figures 2 to 5 As shown, the movement housing 110 may include an inner side surface 111 and a patterned portion 112 disposed on the inner side surface 111. The patterned portion 112 is flush with or protrudes from the inner side surface 111. When the movement housing 110 is accommodated in the receiving groove 211, the inner side surface 111 may face the bottom wall 2111 of the receiving groove 211, and the patterned portion 112 and the bottom wall 2111 of the receiving groove 211 are spaced apart.

[0042] Specifically, the pattern portion 112 can be a logo or indicator pattern, etc., imprinted on the inner surface 111. The pattern portion 112 can be formed and adhered to the inner surface 111 after the paint has cured. Alternatively, the pattern portion 112 can be directly formed or fixed to the inner surface 111 through other processes.

[0043] Since the receiving slot 211 of the charging case 20 is usually designed to match the shape of the housing 110, under normal circumstances, when the earphone 10 is placed in or removed from the charging case 20, the bottom wall 2111 of the receiving slot 211 and the inner side 111 of the housing 110 are prone to continuous contact and friction. Therefore, the pattern 112 on the inner side 111 is easily worn due to friction with the bottom wall 2111 of the receiving slot 211, which weakens the guiding or warning function of the pattern 112 for the user. Therefore, by setting a gap between the pattern 112 and the bottom wall 2111 of the receiving slot 211, the pattern 112 will not come into contact with the bottom wall 2111 of the receiving slot 211. In other words, there is a certain distance between the pattern 112 and the bottom wall 2111 of the receiving slot 211. Therefore, when the earphone 10 is taken out, the wear of the pattern 112 by the bottom wall 2111 of the receiving slot 211 can be reduced, thus protecting the integrity of the pattern 112 and improving the user experience.

[0044] In some embodiments, the patterned portion 112 and the bottom wall 2111 of the receiving groove 211 can be spaced apart in a non-contact manner. Here, non-contact means that a spatial gap is formed between the two objects or structures, that is, they do not contact each other directly or indirectly.

[0045] Specifically, a space is formed between the patterned portion 112 and the bottom wall 2111 of the receiving groove 211, thereby maintaining a gap between the patterned portion 112 and the bottom wall 2111 of the receiving groove 211, which can further reduce the wear of the patterned portion 112.

[0046] The arrangement of creating a space clearance between the pattern part 112 and the bottom wall 2111 of the receiving groove 211 can be verified by various methods. For example, a thin layer of colored ink or paint can be applied to the pattern part 112, and then the earphone 10 can be placed in the receiving groove 211. After that, the earphone 10 can be removed from the receiving groove 211. If the bottom wall of the receiving groove 211 is not covered with the colored ink or paint from the pattern part 112, it indicates that a space clearance and a distance are maintained between the pattern part 112 and the bottom wall 2111 of the receiving groove 211. Alternatively, curable adhesive can be injected into the receiving groove 211 first, and then the earphone 10 can be placed in the receiving groove 211, with the adhesive filling the gap between the earphone 10 and the receiving groove 211. The curable adhesive in the receiving groove 211 can then be cured into a gel. The earphone 10 can then be removed from the receiving groove 211, and the gel can be removed from the receiving groove 211. Observing the thickness of the gel at the corresponding pattern portion 112 position will show that a gap is maintained between the pattern portion 112 and the bottom wall 2111 of the receiving groove 211. Alternatively, a model with the same size and shape as the charging case 20 can be prepared using the charging case 20. Then, the model can be cut along the receiving groove 211, and the earphone 10 can be placed inside. The gap between the earphone 10 and the bottom wall 2111 of the receiving groove in the model can be observed. Other verification methods can also be used to maintain a gap between the pattern portion 112 and the bottom wall 2111 of the receiving groove 211, which will not be specifically listed here in this embodiment.

[0047] Of course, in other embodiments, the patterned portion 112 and the bottom wall 2111 of the receiving groove 211 can be kept apart by other elements. For example, the charging box 20 may include a flexible support pad (not shown) disposed on the bottom wall 2111. The hardness of the flexible support pad may be less than that of the tray 210. When the mechanism housing 110 is placed in the receiving groove 211, the patterned portion 112 can contact the flexible support pad.

[0048] Specifically, when the housing 110 is placed in the receiving groove 211, the flexible support pad supports the patterned part 112, thereby creating a gap between the patterned part 112 and the bottom wall 2111 of the receiving groove 211. Furthermore, because the flexible support pad has low hardness, it can cushion the housing 110 when the earphone 10 is removed from the charging case 20, thus reducing wear on the patterned part 112 and protecting it. Simultaneously, the flexible support pad further limits the positioning of the housing 110, making it more stably placed in the receiving groove 211 and improving the user experience.

[0049] In some embodiments, the interval between the patterned portion 112 and the bottom wall 2111 can be between 0.1 mm and 0.3 mm. For example, the interval between the patterned portion 112 and the bottom wall 2111 can be 0.1 mm, 0.15 mm, 0.2 mm, 0.25 mm, and 0.3 mm.

[0050] As an example, the spacing between the patterned portion 112 and the bottom wall 2111 can be as follows: Figure 5 The intermediate interval L1 is shown, where 0.1mm≤L1≤0.3mm.

[0051] The distance between the patterned portion 112 and the bottom wall 2111 can be measured using an adhesive injection method. This involves injecting curable adhesive into the receiving groove 211, placing the earphone 10 in the groove to fill the space between the groove and the earphone 10, and allowing the adhesive to cure into a gel. The gel is then removed, and the gel can be cut along the long axis of the housing 110 or the long axis of the bottom wall of the receiving groove 211. The thickness of the gel at the corresponding position on the patterned portion 112 is then measured, which represents the distance between the patterned portion 112 and the bottom wall 2111. Alternatively, the earphone 10, the gel, and the charging case 20 can be cut directly along the long axis of the housing 110 or the long axis of the bottom wall of the receiving groove 211 while the adhesive is still cured. The thickness of the gel at the corresponding position on the patterned portion 112 can be measured, or the distance from the patterned portion 112 to the bottom wall of the receiving groove 211 can be directly measured.

[0052] If the area on either side of the colloid position corresponding to the pattern portion 112 is two planes, then the thickness of the colloid position at this location is the shortest distance between the two planes. If the area on either side of the colloid position corresponding to the pattern portion 112 is two curved surfaces, then the first point on one side of the colloid position corresponding to the pattern portion 112 that is closest to the other side is selected, and the second point on the other side that is closest to the colloid position corresponding to the pattern portion 112 is selected. Tangent lines are drawn to these two points respectively, and the shortest distance between the two tangent lines is calculated to obtain the spacing distance between the pattern portion 112 and the bottom wall 2111. If the area on either side of the colloid position corresponding to the pattern portion 112 is a plane and a curved surface, then the point on one side of the curved surface that is closest to the other plane is selected, and the shortest distance from this point to the other plane is calculated to obtain the spacing distance between the pattern portion 112 and the bottom wall 2111.

[0053] If the gap between the patterned part 112 and the bottom wall 2111 is less than 0.1mm, the distance between them will be too close, resulting in poor avoidance. During the placement of the housing 110 into the receiving slot 211, the patterned part 112 may touch the bottom wall 2111 due to the placement angle. Furthermore, users often press the housing 110 when removing the earphones 10, causing it to move closer to the bottom wall 2111. This further reduces the distance between the patterned part 112 and the bottom wall 2111, potentially causing wear and tear. Conversely, if the gap between the patterned part 112 and the bottom wall 2111 is greater than 0.3mm, the receiving slot 211 will be too deep, affecting the size of the charging case 20 and potentially accumulating dust and sweat, thus impacting the user experience.

[0054] Therefore, setting the gap between the pattern part 112 and the bottom wall 2111 to be between 0.1mm and 0.3mm allows the gap between the pattern part 112 and the bottom wall 2111 to form sufficient clearance space, thereby improving the clearance effect and making the pattern part 112 less susceptible to wear from the bottom wall 2111. It also reduces the depth of the receiving groove 211, thereby reducing the size of the charging case 20, preventing the accumulation of sweat, dust and other dirt, and ensuring user experience.

[0055] In some embodiments, such as Figure 2 as well as Figure 3 As shown, the mechanism housing 110 may have a free end 113 and a connecting end 114 disposed opposite to each other. The earphone 10 may include an adapter housing 4 and an elastic hook-shaped portion 5. One end of the adapter housing 4 is connected to the connecting end 114, and the other end of the adapter housing 4 is connected to the elastic hook-shaped portion 5.

[0056] The elastic hook-shaped part 5 is used to hook the earphone 10 onto the auricle when it is worn by the user. The elastic hook-shaped part 5 can elastically deform under the user's operation, making it easy for the user to put on or take off the ear.

[0057] In some embodiments, such as Figure 2 as well as Figure 3As shown, the mechanism housing 110 may include a first housing 115 and a second housing 116, which are snap-fitted together. The speaker 120 can be disposed in the accommodating cavity 102 formed by the first housing 115 and the second housing 116. The first housing 115 forms a connecting end 114, the second housing 116 forms a free end 113, and the inner side 111 is the outer wall surface of the first housing 115 away from the second housing 116. One end of the adapter housing 4 is inserted into and connected to the first housing 115 on the side away from the second housing 116, while the other end is connected to the elastic hook-shaped portion 5.

[0058] In some embodiments, such as Figure 2 as well as Figure 3 As shown, the adapter housing 4 gradually decreases in radial dimension away from the core housing 110, forming a reduced-size structure. Specifically, the larger end of the adapter housing 4 connects to the core housing 110, while the smaller end connects to the elastic hook portion 5. This arrangement allows the adapter housing 4 to act as a transition between the core housing 110 and the elastic hook portion 5. When the earphone 10 is worn on the ear, the adapter housing 4 is located in the transition area between the front and back of the ear, reducing the likelihood of the core housing 110 pressing against the user's head, thereby improving the wearing comfort of the earphone 10. Simultaneously, the adapter housing 4 can be pre-formed with a cavity for accommodating electronic components, independent of the accommodating cavity 102 of the core housing 110, to reduce its space occupation on the core housing 110 and make it more compact.

[0059] In some embodiments, such as Figure 2 as well as Figure 5 As shown, the side of the adapter housing 4 connected to the inner side 111 can be smoothly connected to the inner side 111. The side of the adapter housing 4 connected to the inner side 111 can be accommodated in the receiving groove 211 and abut against the bottom wall 2111 of the receiving groove 211. The receiving groove 211 can also be further adapted to the shape of the adapter housing 4 so that when the adapter housing 4 is placed in the receiving groove 211, the adapter housing 4 can be supported in the receiving groove 211 without external force.

[0060] In some embodiments, such as Figure 5 As shown, when the movement housing 110 is accommodated in the receiving groove 211, the free end 113 and the adapter housing 4 can simultaneously contact the receiving groove 211, so that the patterned part 112 is suspended relative to the bottom wall 2111.

[0061] Specifically, when the movement housing 110 is accommodated in the receiving groove 211, the free end 113 and the adapter housing 4 can simultaneously contact and be supported in the receiving groove 211, so that the inner side surface 111 between the free end 113 and the adapter housing 4 is suspended relative to the bottom wall 2111, thereby keeping the patterned portion 112 of the inner side surface 111 at a distance from the bottom wall 2111.

[0062] By utilizing the interaction and support position between the shell 220 of the earphone 10 and the wall of the receiving groove 211, the patterned part 112 is suspended relative to the bottom wall 2111. This eliminates the need for additional support components on the charging case 20 and the earphone 10 to create a gap, thus simplifying the structure of the charging case 20 and the earphone 10 while achieving an avoidance effect.

[0063] In some embodiments, the minimum distance between the contact area formed by the free end 113 and the receiving groove 211 and the patterned portion 112 may be not less than 4 mm. For example, the minimum distance between the contact area formed by the free end 113 and the receiving groove 211 and the patterned portion 112 may be 4 mm, 4.5 mm, 5 mm, 5.5 mm, 6 mm, 6.5 mm or 7 mm, etc.

[0064] As an example, the minimum spacing between the contact area formed by the free end 113 and the receiving groove 211 and the patterned portion 112 can be as follows: Figure 5 As shown in L2.

[0065] Specifically, the contact area formed by the free end 113 and the receiving groove 211 refers to the portion of the free end 113 that contacts the wall of the receiving groove 211; in other words, it is also the portion of the wall of the receiving groove 211 that contacts the free end 113. By setting the minimum distance between the contact area formed by the free end 113 and the receiving groove 211 and the patterned portion 112 to be no less than 4 mm, the patterned portion 112 can maintain a certain distance from the portion of the receiving groove 211 that contacts the free end 113. At this time, when the free end 113 is supported on the aforementioned contact area of ​​the receiving groove 211, the patterned portion 112 can be kept as far away from the aforementioned contact area as possible, so as to ensure that the patterned portion 112 can maintain a certain distance from the bottom wall of the receiving groove 211.

[0066] If the minimum distance between the contact area formed by the free end 113 and the receiving groove 211 and the patterned part 112 is less than 4mm, the contact area formed by the free end 113 and the receiving groove 211 and the patterned part 112 will be close. When the earphone 10 is placed in the charging case 20, the patterned part 112 may still rub against the bottom wall 2111 of the receiving groove 211 due to the placement angle, which will cause the patterned part 112 to wear to a certain extent and make the avoidance effect worse.

[0067] In some embodiments, the bottom wall 2111 of the receiving groove 211 may be recessed so that the patterned portion 112 is spaced apart from the bottom wall 2111. Therefore, if the distance between the contact area formed by the free end 113 and the receiving groove 211 and the patterned portion 112 is too close, the distance between the bottom wall 2111 of the receiving groove 211 and the part of the receiving groove 211 that contacts the free end 113 will also be close, resulting in a more obvious step-like depth difference, which will form an obvious recessed boundary. During the process of placing the movement housing 110 in or removing it from the receiving groove 211, the patterned portion 112 is likely to touch the recessed boundary and cause wear.

[0068] Therefore, by setting the minimum distance between the contact area formed by the free end 113 and the receiving groove 211 and the patterned part 112 to be no less than 4mm, the part of the receiving groove 211 that contacts the free end 113 can have a smooth transition to the bottom wall 2111 without a relatively obvious recessed boundary. This makes it less likely for the patterned part 112 to touch the contact area or recessed boundary and cause wear while maintaining a distance from the bottom wall 2111.

[0069] In some embodiments, such as Figures 2 to 7 As shown, the movement housing 110 may include an outer side 117 disposed opposite to the inner side 111, and an upper side 118 and a lower side 119 connecting the free end 113 and the connecting end 114. The upper side 118 and the lower side 119 are disposed opposite to each other. Specifically, in the spacing direction between the inner side 111 and the outer side 117, one end of the upper side 118 and one end of the lower side 119 are respectively connected to the outer side 117, and the other end of the upper side 118 and the other end of the lower side 119 are respectively connected to the inner side 111.

[0070] like Figure 7 As shown, at least a portion of the upper side 118 and at least a portion of the lower side 119 can respectively contact the wall of the receiving groove 211. Since the free end 113 and the adapter housing 4 can also contact the wall of the receiving groove 211, when the movement housing 110 is placed in the receiving groove 211, the free end 113 surrounding the inner side 111, the upper side 118, the lower side 119, and the adapter housing 4 can all contact the receiving groove 211. This allows the wall of the receiving groove 211 to more stably support the movement housing 110, while allowing the patterned part 112 to be suspended relative to the bottom wall 2111 of the receiving groove 211. This arrangement ensures the avoidance effect of the patterned part 112 and prevents the movement housing 110 from shaking or shifting in the receiving groove 211, thus avoiding further wear on other parts of the movement housing 110.

[0071] The minimum distance between the contact area formed by the upper side surface 118 and the receiving groove 211 and the patterned portion 112 can be no less than 1.5 mm. For example, the minimum distance between the contact area formed by the upper side surface 118 and the receiving groove 211 and the patterned portion 112 can be 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm or 4 mm, etc.

[0072] As an example, the minimum spacing between the contact area formed by the upper side surface 118 and the receiving groove 211 and the patterned portion 112 can be as follows: Figure 7 As shown in L3.

[0073] Specifically, the contact area formed by the upper side surface 118 and the receiving groove 211 refers to the portion of the upper side surface 118 that contacts the wall of the receiving groove 211; in other words, it is also the portion of the wall of the receiving groove 211 that contacts the upper side surface 118. By setting the minimum distance between the contact area formed by the upper side surface 118 and the receiving groove 211 and the patterned portion 112 to be no less than 1.5 mm, the patterned portion 112 can maintain a certain distance from the portion of the receiving groove 211 that contacts the upper side surface 118. At this time, when the upper side surface 118 is supported on the wall of the receiving groove 211, the patterned portion 112 can be kept as far away as possible from the contact area formed by the upper side surface 118 and the receiving groove 211, so as to ensure that the patterned portion 112 can maintain a certain distance from the bottom wall of the receiving groove 211.

[0074] Specifically, if the minimum distance between the contact area formed by the upper side 118 and the receiving groove 211 and the patterned part 112 is less than 1.5 mm, the contact area formed by the upper side 118 and the receiving groove 211 will be too close to the patterned part 112, and the part of the receiving groove 211 that contacts the upper side 118 will also be too close to the bottom wall 2111. Since the bottom wall 2111 of the receiving groove 211 needs to maintain a distance from the patterned part 112, a relatively obvious depth difference will be formed between the part of the receiving groove 211 that contacts the upper side 118 and the bottom wall 2111 of the receiving groove 211, thus forming a recessed boundary similar to a step. During the process of placing the movement housing 110 into or removing it from the receiving groove 211, the patterned part 112 will touch the contact area or the recessed boundary, causing wear.

[0075] Therefore, by setting the minimum distance between the contact area formed by the upper side 118 and the receiving groove 211 and the patterned part 112 to not less than 1.5mm, the part of the receiving groove 211 that contacts the upper side 118 can have a smooth transition with the bottom wall 2111 of the receiving groove 211 without a relatively obvious recessed boundary. This makes it less likely for the patterned part 112 to touch the contact area formed by the upper side 118 and the receiving groove 211 or the recessed boundary of the receiving groove 211 and cause wear.

[0076] In some embodiments, the minimum distance between the contact area formed by the lower side surface 119 and the receiving groove 211 and the patterned portion 112 may be not less than 1.5 mm. For example, the minimum distance between the contact area formed by the lower side surface 119 and the receiving groove 211 and the patterned portion 112 may be 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm or 4 mm or other values.

[0077] As an example, the minimum spacing between the contact area formed by the lower side surface 119 and the receiving groove 211 and the patterned portion 112 can be as follows: Figure 7 As shown in L4.

[0078] Specifically, the contact area formed by the lower side surface 119 and the receiving groove 211 refers to the portion of the lower side surface 119 that contacts the wall of the receiving groove 211; in other words, it is also the portion of the wall of the receiving groove 211 that contacts the lower side surface 119. By setting the minimum distance between the contact area formed by the lower side surface 119 and the receiving groove 211 and the patterned portion 112 to be no less than 1.5 mm, the patterned portion 112 can maintain a certain distance from the portion of the receiving groove 211 that contacts the lower side surface 119. At this time, when the lower side surface 119 is supported on the wall of the receiving groove 211, the patterned portion 112 can be kept as far away as possible from the contact area formed by the lower side surface 119 and the receiving groove 211, so as to ensure that the patterned portion 112 can maintain a certain distance from the bottom wall of the receiving groove 211.

[0079] If the minimum distance between the contact area formed by the lower side surface 119 and the receiving groove 211 and the patterned part 112 is less than 1.5 mm, the contact area formed by the lower side surface 119 and the receiving groove 211 will be too close to the patterned part 112, and the part of the receiving groove 211 that contacts the lower side surface 119 will also be too close to the bottom wall 2111 of the receiving groove 211. Since the bottom wall 2111 of the receiving groove 211 needs to maintain a distance from the patterned part 112, a relatively obvious depth difference will be formed between the part of the receiving groove 211 that contacts the lower side surface 119 and the bottom wall 2111 of the receiving groove 211, thus forming a recessed boundary similar to a step. During the process of placing the movement housing 110 into or removing it from the receiving groove 211, the patterned part 112 will touch the contact area or the recessed boundary, causing wear.

[0080] Therefore, by setting the minimum distance between the contact area formed by the lower side surface 119 and the receiving groove 211 and the patterned part 112 to not less than 1.5 mm, the part of the receiving groove 211 that contacts the lower side surface 119 can have a smooth transition with the bottom wall 2111 of the receiving groove 211 without a relatively obvious recessed boundary. This makes it less likely for the patterned part 112 to touch the contact area formed by the lower side surface 119 and the receiving groove 211 or the recessed boundary of the receiving groove 211 and cause wear.

[0081] In some embodiments, the minimum distance between the contact area formed by the adapter housing 4 and the receiving groove 211 and the patterned portion 112 may be not less than 10 mm. For example, the minimum distance between the contact area formed by the adapter housing 4 and the receiving groove 211 and the patterned portion 112 may be 10 mm, 10.5 mm, 11 mm, 11.5 mm, 12 mm, 12.5 mm or 13 mm or other values.

[0082] As an example, the minimum spacing between the contact area formed by the adapter housing 4 and the receiving groove 211 and the patterned portion 112 can be as follows: Figure 5 As shown in L5.

[0083] If the minimum distance between the contact area formed by the adapter housing 4 and the receiving groove 211 and the patterned part 112 is less than 10mm, the contact area formed by the adapter housing 4 and the receiving groove 211 will be too close to the patterned part 112, and the part of the receiving groove 211 that contacts the adapter housing 4 will also be too close to the bottom wall 2111 of the receiving groove 211. Since the bottom wall 2111 of the receiving groove 211 needs to maintain a distance from the patterned part 112, a relatively obvious depth difference will be formed between the part of the receiving groove 211 that contacts the adapter housing 4 and the bottom wall 2111 of the receiving groove 211, thus forming a recessed boundary similar to a step. During the process of placing the movement housing 110 into or removing it from the receiving groove 211, the patterned part 112 will touch the aforementioned contact area or recessed boundary, causing wear.

[0084] Therefore, by setting the minimum distance between the contact area formed by the adapter housing 4 and the receiving groove 211 and the patterned part 112 to not less than 10mm, a smooth transition can be achieved between the part of the receiving groove 211 that contacts the adapter housing 4 and the bottom wall 2111 of the receiving groove 211, so that there is no obvious recessed boundary. This makes it less likely for the patterned part 112 to touch the contact area and recessed boundary formed by the adapter housing 4 and the receiving groove 211, thus reducing the risk of wear on the patterned part 112.

[0085] In some embodiments, the movement housing 110 has a thickness direction, and the thickness of the patterned portion 112 in the thickness direction of the movement housing 110 can be less than 0.05 mm. The thickness direction can be the spacing direction between the inner side surface 111 and the outer side surface 117 of the movement housing 110.

[0086] Where both the inner surface 111 and the outer surface 117 are planes or have planar regions, the direction of the interval between the inner surface 111 and the outer surface 117 is the direction of the common perpendicular line of the two planes. In some embodiments, where one of the inner surface 111 and the outer surface 117 is a plane and the other is a curved surface, the direction of the perpendicular line from any point on the curved surface to the plane is the direction of the interval between the inner surface 111 and the outer surface 117. If both the inner surface 111 and the outer surface 117 are curved surfaces, the vertex furthest from each other in the inner surface 111 and the outer surface 117 are selected, and tangent lines are drawn from these two points. The direction of the common perpendicular line of these two tangent lines is the direction of the interval between the inner surface 111 and the outer surface 117.

[0087] As an example, the thickness direction of the movement housing 110 can be as follows: Figure 7 The direction indicated by the middle arrow C. For example, the thickness of the patterned part 112 in the thickness direction C can be 0.05mm, 0.04mm, 0.03mm, 0.02mm or 0.01mm, etc.

[0088] Specifically, the thickness of the patterned portion 112 in the thickness direction C is less than 0.05 mm. In other words, the protrusion of the patterned portion 112 relative to the inner surface 111 in the thickness direction C is less than 0.05 mm.

[0089] If the thickness of the pattern portion 112 in the thickness direction C is greater than 0.05 mm, the protrusion of the pattern portion 112 relative to the inner surface 111 will be relatively large, making the pattern portion 112 more susceptible to wear. Therefore, by setting the thickness of the pattern portion 112 in the thickness direction C to be less than 0.05 mm, the pattern portion 112 provided on the inner surface 111 will not protrude too much, thereby reducing the risk of wear on the pattern portion 112 while ensuring its navigation or warning functions.

[0090] In some embodiments, such as Figure 2 as well as Figure 5 As shown, the inner surface 111 may include a peripheral region 1111 surrounding the pattern portion 112. The peripheral region 1111 may be spaced apart from the bottom wall 2111 of the receiving groove 211 in a non-contact manner, and the total area of ​​the peripheral region 1111 is not less than twice the area of ​​the pattern portion 112.

[0091] Specifically, the patterned portion 112 is spaced apart from the bottom wall 2111 of the receiving groove 211, and the outer region 1111 separates the edge of the inner side 111 from the patterned portion 112. Therefore, the bottom wall 2111 can have enough space to avoid the patterned portion 112, and the receiving groove 211 can form a smooth transition between the portion corresponding to the patterned portion 112 and the contact area between the receiving groove 211 and the movement housing 110, so as to reduce wear on the patterned portion 112.

[0092] If the total area of ​​the outer region 1111 is less than twice the area of ​​the patterned part 112, the edge of the patterned part 112 and the inner side 111 will be too close. The part of the bottom wall 2111 corresponding to the patterned part 112 and the contact area between the receiving groove 211 and the contact area of ​​the movement housing 110 will easily form an obvious depression, which will increase the risk of wear of the patterned part 112.

[0093] In some embodiments, such as Figure 5 as well as Figure 7 As shown, the distance between the inner side surface 111 and the bottom wall 2111 can gradually decrease in the direction away from the pattern portion 112. In other words, the distance between the pattern portion 112 and the bottom wall 2111 is the maximum distance between the inner side surface 111 of the movement housing 110 and the bottom wall 2111 of the receiving groove 211. Furthermore, with the pattern portion 112 as the center, the distance between the inner side surface 111 and the bottom wall 2111 gradually decreases in the direction away from the pattern portion 112 until the movement housing 110 is supported within the receiving groove 211. This arrangement allows for a smooth connection between the area between the bottom wall 2111 and the movement housing 110, as well as the supporting area. The bottom wall 2111 is less likely to have sharp abrupt changes or areas with large curvature changes, preventing these areas from bumping against the movement housing 110 and causing wear. It also improves the aesthetics of the bottom wall 2111.

[0094] In some embodiments, such as Figure 2 As shown, the inner side 111 may be provided with at least one sound outlet 101, and the sound generated by the speaker 120 is transmitted to the outside of the earphone 10 through the sound outlet 101. The patterned part 112 is disposed around at least part of the periphery of the sound outlet 101.

[0095] Specifically, the arrangement of the patterned portion 112 around at least part of the sound outlet 101 can improve the space utilization of the inner side 111, while also serving as a guide for the user and enhancing the surface aesthetics of the movement housing 110.

[0096] In some embodiments, such as Figure 2 as well as Figure 3As shown, the loudspeaker 120 may include a main loudspeaker 121 and an auxiliary loudspeaker 122. The sound outlet 101 may include a first sound outlet 1011 corresponding to the main loudspeaker 121 and a second sound outlet 1012 corresponding to the auxiliary loudspeaker 122. The first sound outlet 1011 is semi-enclosed and surrounds the periphery of the second sound outlet 1012. The patterned portion 112 is surrounded by the periphery of the second sound outlet 1012 and is located between the second sound outlet 1012 and the first sound outlet 1011.

[0097] The main speaker 121 and the auxiliary speaker 122 can be air-conducting speakers 120, both of which can convert electrical signals into sound signals (also known as "sound waves" or "sound signals") and transmit them to the wearer's ears.

[0098] When the earphone 10 is worn on the user's ear, the free end 113 of the earphone 10 can abut against the concha cavity of the user's ear. The first sound outlet 1011 and the second sound outlet 1012 are located on the inner side 111 near the free end 113, so that the sound waves propagated by the first sound outlet 1011 and the second sound outlet 1012 can be propagated into the user's external auditory canal.

[0099] By placing the pattern portion 112 between the second sound outlet 1012 and the first sound outlet 1011, and surrounding the periphery of the second sound outlet 1012, on the one hand, the space between the second sound outlet 1012 and the first sound outlet 1011 can be utilized to reduce the space occupied by the pattern portion 112 on the inner side surface 111, thereby improving the space utilization rate of the inner side surface 111. On the other hand, the surface aesthetics of the movement housing 110 can also be improved.

[0100] In some embodiments, such as Figure 8 as well as Figure 9 As shown, the charging case 20 may include a housing 220 and a button assembly 230.

[0101] In some embodiments, the internal accommodating space 201 of the housing 220 of the charging case 20 may contain components such as circuit boards and batteries. The button assembly 230 may be electrically connected to the circuit board, and the user may use the button assembly 230 to trigger the power on / off of the charging case 20 or adjust functions such as charging or Bluetooth connection.

[0102] Specifically, such as Figures 8 to 10 As shown, a button hole 221 is provided on the housing 220. Figure 10 As shown, the button assembly 230 may include a button body 231 disposed in the button hole 221 and a connecting arm 232 that elastically supports the button body 231.

[0103] The button body 231 is exposed on the outer surface of the housing 220 through the button hole 221, allowing the user to press the button body 231. The connecting arm 232 connects the button body 231 and the housing 220, indirectly fixing the button body 231 to the housing 220 so that the button body 231 is not easy to fall out of the housing 220, while also allowing the button body 231 to have sufficient movement.

[0104] like Figure 10 As shown, the connecting arm 232 may include a first arm segment 2321 and a second arm segment 2322 connected to each other, with the extension directions of the first arm segment 2321 and the second arm segment 2322 intersecting. The first end of the first arm segment 2321 is connected to the housing 220, and the first end of the second arm segment 2322 is connected to the second end of the first arm segment 2321. The second end of the second arm segment 2322 is connected to the button body 231. The length of the first arm segment 2321 is less than the length of the second arm segment 2322.

[0105] The fact that the extension directions of the first arm segment 2321 and the second arm segment 2322 are intersected means that the length extension direction of the first arm segment 2321 and the length extension direction of the second arm segment 2322 intersect each other to form a certain angle, so that the connecting arm 232 presents a bent strip shape.

[0106] Compared to the existing technology that uses a long straight arm segment to connect the housing 220 and the button body 231, setting the connecting arm 232 as two intersecting arm segments can reduce the length of the connecting arm 232 in a single extension direction. Therefore, without reserving a long space in the housing 220 to install the connecting arm 232, the button body 231 can have sufficient movement stroke to ensure the triggering of the button function. At the same time, it can make it easier for the connecting arm 232 to avoid other components set on the housing 220, thereby improving the space utilization of the charging case 20.

[0107] As an example, the length of the first arm segment 2321 can be shown as length L6 in the figure, and the length of the second arm segment 2322 can be shown as length L7 in the figure. Wherein, L6 < L7.

[0108] The length of the first arm segment 2321 refers to the length of the first arm segment 2321 that can undergo elastic deformation to support the movement of the second arm segment 2322. The length of the second arm segment 2322 refers to the length of the second arm segment 2322 that can undergo elastic deformation to support the movement of the button body 231.

[0109] Specifically, since the deformation of the second arm segment 2322 connected to the button body 231 is greater than that of the first arm segment 2321 when the button body 231 is displaced by the user, setting the length of the second arm segment 2322 to be greater than the length of the first arm segment 2321 can ensure that the button body 231 has sufficient movement stroke to trigger the button function of the charging box 20, thereby improving the user experience.

[0110] In some embodiments, the ratio of the length of the first arm segment 2321 to the length of the second arm segment 2322 can be between 0.2 and 0.5. For example, the ratio of the length of the first arm segment 2321 to the length of the second arm segment 2322 can be 0.2, 0.27, 0.3, 0.35, 0.4, 0.45, or 0.5.

[0111] If the ratio of the length of the first arm segment 2321 to the length of the second arm segment 2322 is less than 0.2, it indicates that the second arm segment 2322 is too long, thus occupying more space in the length extension direction of the second arm segment 2322 and creating redundancy in the travel during the movement of the button body 231. If the ratio of the length of the first arm segment 2321 to the length of the second arm segment 2322 is greater than 0.5, it indicates that the second arm segment 2322 is too short. During the pressing of the button body 231 by the user, the second arm segment 2322 is difficult to deform, making it difficult for the button body 231 to be pressed and moved by the user. At the same time, in order to ensure the travel of the button body 231, the user needs to apply greater pressing force, and the first arm segment 2321 and the second arm segment 2322 are prone to breakage.

[0112] Therefore, setting the ratio of the length of the first arm segment 2321 to the length of the second arm segment 2322 to 0.2-0.5 not only reduces the space occupied by the second arm segment 2322 in its length extension direction, but also makes it easier for the button body 231 to be pressed by the user. The first arm segment 2321 and the second arm segment 2322 are also less likely to break during the process of the button body 231 being pressed by the user.

[0113] In some embodiments, the button body 231 may be circular, and the total length of the connecting arm 232 may be greater than the diameter of the button body 231, but not more than twice the diameter of the button body 231.

[0114] Specifically, if the total length of the connecting arm 232 is less than or equal to the diameter of the button body 231, the connecting arm 232 is too short. When the button body 231 is pressed, the connecting arm 232 cannot deform sufficiently to meet the movement stroke requirements of the button body 231, thus making it difficult to trigger the button function. If the total length of the connecting arm 232 is greater than twice the diameter of the button body 231, the connecting arm 232 is too long. On the one hand, it occupies more internal space of the housing 220, and on the other hand, it causes excessive redundancy in the movement stroke of the button body 231, resulting in poor triggering after multiple presses.

[0115] Therefore, setting the total length of the connecting arm 232 to be greater than the diameter of the button body 231 but not more than twice the diameter of the button body 231 not only ensures that the connecting arm 232 has sufficient deformation to guarantee the movement stroke of the button body 231, but also prevents the connecting arm 232 from occupying too much space, improving the space utilization rate inside the housing 220, while also preventing the button body 231 from having too much stroke redundancy.

[0116] In some embodiments, the total length of the connecting arm 232 can be between 6mm and 12mm. For example, the total length of the connecting arm 232 can be 6mm, 7mm, 8mm, 9mm, 10mm, 11mm or 12mm.

[0117] Specifically, if the total length of the connecting arm 232 is less than 6mm, it indicates that the connecting arm 232 is too short. When the button body 231 is pressed, the connecting arm 232 cannot deform sufficiently to meet the movement stroke requirements of the button body 231, thus making it difficult to trigger the button function. If the total length of the connecting arm 232 is greater than 12mm, it indicates that the connecting arm 232 is too long. On the one hand, it occupies more internal space of the housing 220, and on the other hand, it causes too much redundancy in the movement stroke of the button body 231, resulting in poor triggering after multiple presses.

[0118] Therefore, setting the total length of the connecting arm 232 between 6mm and 12mm not only allows the connecting arm 232 to have sufficient deformation to ensure the movement stroke of the button body 231, but also prevents the connecting arm 232 from occupying too much space, improving the space utilization rate inside the housing 220, while also preventing the button body 231 from having too much stroke redundancy.

[0119] In some embodiments, the connecting arm 232 may include a first direction extending along the first arm segment 2321 and a second direction extending along the second arm segment 2322. The included angle α between the first direction and the second direction is within 80°-120°. For example, the included angle α between the first direction and the second direction can be 80°, 85°, 90°, 95°, 100°, 105°, 110°, 115°, or 120°.

[0120] As an example, the first direction in which the first arm segment 2321 extends can be as follows: Figure 10 As shown in the middle direction E, the second direction of the extension of the second arm segment 2322 can be as follows: Figure 10 As shown in the middle direction F, the angle between the first direction E and the second direction F can be as follows: Figure 10 As shown by angle α.

[0121] Specifically, if the angle α between the first direction E and the second direction F is less than 80°, it indicates that the bending degree at the connection between the first arm segment 2321 and the second arm segment 2322 is relatively large. During the process of the button body 231 being pressed and causing the second arm segment 2322 to deform, the connection between the first arm segment 2321 and the second arm segment 2322 is prone to breakage, and the first arm segment 2321 is difficult to deform under the influence of the second arm segment 2322, thus making it difficult to press the button body 231. If the angle α between the first direction E and the second direction F is greater than 120°, it indicates that the first arm segment 2321 and the second arm segment 2322 are close to a straight line, thus causing the connecting arm 232 to occupy a large space in one direction.

[0122] Therefore, setting the angle α between the first direction E extending along the first arm segment 2321 and the second direction F extending along the second arm segment 2322 to 80°-120° not only facilitates the pressing of the button body 231 and reduces the risk of breakage at the connection between the first arm segment 2321 and the second arm segment 2322, but also reduces the space occupied by the connecting arm 232 in one direction, thereby improving the space utilization of the charging box 20.

[0123] In some embodiments, such as Figure 10 As shown, the connecting arm 232 may further include a third arm segment 2323. The extending direction of the third arm segment 2323 intersects the extending direction of the second arm segment 2322. The second end of the second arm segment 2322 is connected to the first end of the third arm segment 2323, and the second end of the third arm segment 2323 is connected to the button body 231.

[0124] The length of the third arm segment 2323 is less than the length of the first arm segment 2321. The extension direction of the first arm segment 2321 is substantially parallel to the extension direction of the third arm segment 2323. "Substantially parallel" means that the angle between the extension directions of the first arm segment 2321 and the third arm segment 2323 is less than 10°.

[0125] Specifically, the second arm segment 2322 is connected to the button body 231 via the third arm segment 2323. By setting the extension direction of the first arm segment 2321 to be substantially parallel to the extension direction of the third arm segment 2323, the connecting arm 232 can better support the button body 231, enhance the connection stability between the connecting arm 232 and the button body 231, reduce the risk of breakage due to large torsional forces at the connection points of the connecting arm segments during pressing, thereby improving the structural stability of the button assembly 230 and also improving the pressing effect of the button body 231.

[0126] In some embodiments, such as Figure 8 as well as Figure 9 As shown, the housing 220 may include a lower housing 222, a support plate 210, and an upper housing 223.

[0127] The lower shell 222 and the support plate 210 can be assembled to form an accommodating space 201. The upper shell 223 and the lower shell 222 are pivotally connected to each other about a predetermined rotation axis, and the support plate 210 covers them when they are fastened together. As an example, the rotation axis can be as follows: Figure 8 As shown by the midline LH.

[0128] During the opening of the charging case 20, the upper shell 223 rotates around a preset rotation axis LH, thereby gradually exposing the tray 210. During the closing of the charging case 20, the upper shell 223 rotates around the preset rotation axis LH and gradually closes the lower shell 222, covering the tray 210. The state of the charging case 20 when the upper shell 223 is open relative to the lower shell 222 is as follows: Figure 8 As shown, the state of the charging case 20 when the upper shell 223 is closed relative to the lower shell 222 can be as follows: Figure 11 As shown.

[0129] like Figure 8 as well as Figure 9 As shown, the tray 210 may include a recessed groove 212 and a platform area 213. The recessed groove 212 can be used to accommodate the earphone 10. The platform area 213 may be located on the side of the recessed groove 212 away from the rotation axis LH, and the button hole 221 may be provided in the platform area 213. The connecting arm 232 may be provided in the accommodating space 201, and the first end of the first arm segment 2321 may be fixed to the side of the platform area 213 facing the accommodating space 201.

[0130] Specifically, the button hole 221 is positioned on the platform area 213, which is offset from the rotation axis LH. This ensures that when the earphone 10 is placed in the recessed groove 212, the button hole 221 and the button body 231 on the platform area 213 are not obstructed. The platform area 213 is closer to the opening end of the charging case 20, making it easier for users to open the charging case 20 and directly perform button control operations. This is more in line with users' operating habits and improves the user experience.

[0131] By attaching the first end of the first arm segment 2321 to the side of the platform area 213 facing the receiving space 201, the other parts of the connecting arm 232 can be suspended in the receiving space 201, thus facilitating the pressing of the button body 231. Specifically, when the button body 231 is pressed, it can move towards the receiving space 201 away from the tray 210, thereby triggering the button unit on the corresponding circuit board. The button body 231 causes the connecting arm 232 to undergo elastic deformation. When the user stops pressing the button body 231, the connecting arm 232 can elastically recover, causing the button body 231 to move back to its original position.

[0132] In some embodiments, the dimension of the platform region 213 parallel to the rotation axis LH gradually increases in the direction away from the rotation axis LH. As an example, such as... Figure 8 As shown, the dimensions of platform region 213 in the direction parallel to the rotation axis LH can be as follows: Figure 8 As shown in L8, L8 gradually increases in the direction away from the rotation axis LH.

[0133] In some embodiments, the button body 231 is closer to the rotation axis LH, and the connecting arm 232 is further away from the rotation axis LH. Since the platform area 213 is larger in size away from the rotation axis LH, setting the connecting arm 232 further away from the rotation axis LH allows sufficient space on the platform area 213 to accommodate the connecting arm 232, thereby improving space utilization.

[0134] In some embodiments, the first arm segment 2321 is farther from the rotation axis LH than the third arm segment 2323. The extension directions of the first arm segment 2321 and the third arm segment 2323 are substantially parallel to the rotation axis LH, and the extension direction of the second arm segment 2322 is substantially perpendicular to the rotation axis LH. "Substantially parallel" means that the angle between the extension directions of the first arm segment 2321 and the third arm segment 2323 and the rotation axis LH is less than 10°. "Substantially perpendicular" means that the angle between the extension direction of the second arm segment 2322 and the rotation axis LH is between 80° and 100°.

[0135] Since the length of the first arm segment 2321 is greater than the length of the third arm segment 2323, setting the first arm segment 2321 further away from the rotation axis LH compared to the third arm segment 2323 allows the first arm segment 2321 to be located at the larger end of the platform area 213. The fact that the extension direction of the second arm segment 2322 is basically perpendicular to the rotation axis LH allows the first arm segment 2321 and the second arm segment 2322 to occupy less space in the extension direction of the first arm segment 2321. This arrangement allows the button assembly 230 to adapt to the size of the platform area 213, fully utilizing the space of the platform area 213 on the tray 210, thereby improving space utilization.

[0136] In some embodiments, such as Figure 12 as well as Figure 13 As shown, the first end of the first arm segment 2321 can be fixed to the support plate 210. The support plate 210 may further include a fastener 214 and a reinforcing rib 215. The fastener 214 is used to engage with the lower shell 222 so that the support plate 210 and the lower shell 222 are connected and fitted. The reinforcing rib 215 is used to support the fastener 214, so that the fastener 214 is not easily deformed, and thus the fastener 214 is not easily dislodged from the engagement with the lower shell 222.

[0137] The reinforcing rib 215 and the fastener 214 can cooperate to form a positioning area 216, and the first end of the first arm segment 2321 can be fixed in the positioning area 216. By reusing the positioning area 216 formed by the fastener 214 and the reinforcing rib 215 to position the first end of the first arm segment 2321, there is no need to set additional positioning components on the tray 210, which can improve space utilization and facilitate the fixed installation of the first arm segment 2321 on the tray 210, thereby reducing the installation difficulty of the button assembly 230.

[0138] In some embodiments, such as Figure 13 As shown, the tray 210 may further include a mounting position 217 disposed on the platform area 213 facing the receiving space 201 and adjacent to the button hole 221. The second arm segment 2322 is located between the mounting position 217 and the button hole 221, and the first arm segment 2321 is located on the side of the mounting position 217 away from the recess 212.

[0139] The mounting position 217 can be used to mount other components in the charging box 20, such as magnetic components or magnetic conductive components.

[0140] Specifically, the shape formed by the first arm segment 2321 and the second arm segment 2322 is an "L" shape or a similar "L" shape. Therefore, the mounting position 217 is set in the clearance space formed by the first arm segment 2321 and the second arm segment 2322, so that the first arm segment 2321 is located on the side of the mounting position 217 away from the recessed groove 212, and the second arm segment 2322 is located between the mounting position 217 and the button hole 221. This can make the components corresponding to the platform area 213 more neatly arranged and can also improve the space utilization of the charging box 20.

[0141] In some embodiments, the number of mounting positions 217 and connecting arms 232 may be two each, and they are arranged on both sides of the key hole 221 in a direction substantially parallel to the rotation axis LH. The two mounting positions 217 are symmetrically arranged with respect to the key hole 221, and the two connecting arms 232 are symmetrically arranged with respect to the key hole 221.

[0142] For example, one of the two mounting positions 217 is equipped with a magnetic attractor, and the other can be equipped with a magnetic conductor. The second arm segment 2322 of the two connecting arms 232 is located between the two mounting positions 217, and the first arm segment 2321 of the two connecting arms 232 is respectively located on the side of the mounting position 217 away from the recessed groove 212.

[0143] By symmetrically arranging two connecting arms 232 along the rotation axis LH on both sides of the button hole 221, the connecting arms 232 can better support the button body 231, making the structure of the button assembly 230 more stable. When the button body 231 is pressed, the two connecting arms 232 can share the pressure of the button body 231 being pressed, thereby reducing the possibility of the two connecting arms 232 breaking and increasing the service life of the connecting arms 232. At the same time, the button body 231 is less likely to shift and can be reset better.

[0144] In summary, since the receiving slot 211 of the charging case 20 is usually configured such that the bottom wall 2111 of the receiving slot 211 contacts the inner side 111 of the core housing 110, and the patterned portion 112 on the inner side 111 is easily worn by the friction of the bottom wall 2111 of the receiving slot 211, this application sets the patterned portion 112 on the earphone 10 and the bottom wall 2111 of the charging case 20 at a distance, so that when the earphone 1 is placed in the charging case 20, the patterned portion 112 on the core housing 110 of the earphone 1 will not contact the bottom wall 2111 of the receiving slot 211. This reduces the wear of the patterned portion 112 on the bottom wall 2111 of the receiving slot 211 during repeated taking and putting of the earphone 1, thus protecting the integrity of the patterned portion 112 and ensuring user experience.

Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
