[0036] 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.
[0037] Bluetooth earphones are becoming increasingly popular in daily life. The charging case, serving as a storage and charging tool for Bluetooth earphones, needs to stably house them. Because the earphones' charging position is fixed within the case, a high degree of precision is required to ensure effective electrical contact. One type of Bluetooth earphone is the open-back model, consisting of the earphone body and ear hooks. In related technologies, the charging case has a slot for holding these earphones, with the charging probes located at the bottom of the slot and corresponding to the earphone body. During use, the open-back earphones may become loose within the case, leading to poor contact between the earphone body and the charging probes, affecting charging efficiency and speed.
[0038] For the above situation, please refer to Figures 1-2 This application proposes an earphone case 100, including a cover 10, a case 20, and a charging component 30. The earphone case 100 can be used to store open-back earphones 200, and the charging component 30 can be used to charge the open-back earphones 200. The connection between the cover 10 and the case 20 can be a rotatable connection or a detachable connection, such as a snap-fit, magnetic, or sliding connection. For example, the cover 10 is rotatably connected to the case 20 via a pivot, and the case 20 is provided with a charging port for electrical connection with a charging plug to connect to the charging component 30 inside the earphone case 100. The charging port is located on the side of the case 20 near the pivot, thereby reducing interference from the charging cable on the rotation and opening / closing of the cover 10.
[0039] like Figures 2-4 As shown, the housing 20 has a contoured groove 21 for housing the earphones 200. The inner sidewall of the contoured groove 21 includes a first sidewall 211, a second sidewall 212, and a third sidewall 213 connected in sequence. That is, the first sidewall 211, the second sidewall 212, and the third sidewall 213 are connected in sequence to form the contoured groove 21. The charging assembly 30 includes a first charging component 31 and a second charging component 32. The first charging component 31 is disposed on the second sidewall 212, and the second charging component 32 is disposed on at least one of the first sidewall 211 and the third sidewall 213. Both the first charging component 31 and the second charging component 32 can extend and retract relative to the inner sidewall of the contoured groove 21 to make electrical contact with the earphones 200.
[0040] Specifically, such as Figure 3 As shown, the surface of the earphone 200 has multiple charging sections 50. When the earphone 200 is placed in the contoured groove 21, different charging sections 50 will successively contact the second charging component 32 and the first charging component 31, pushing the second charging component 32 and the first charging component 31 to retract, so that the charging section 50 of the earphone 200 is electrically connected to the first charging component 31 and the second charging section 50 in the contoured groove 21. The first charging component 31 and the second charging component 32 are both connected to the housing 20 by springs, so that the earphone 200 can push the first charging component 31 and the second charging component 32 to retract relative to the inner wall of the contoured groove 21, and the springs can also drive the first charging component 31 and the second charging component 32 to extend and return to their original position relative to the inner wall of the contoured groove 21.
[0041] It should be noted that during use, if the earphone 200 experiences slight displacement within the contoured groove 21, the charging component located at the bottom of the contoured groove 21 may not align correctly with the charging section 50 of the earphone 200, potentially leading to poor charging contact. In this embodiment, the first charging component 31 and the second charging component 32 are respectively disposed on the second sidewall 212, the first sidewall 211, and / or the third sidewall 213. That is, the first charging component 31 and the second charging component 32 are respectively disposed on the bottom wall and sidewall of the contoured groove 21. By distributing charging components on different sidewalls of the contoured groove 21, the number of charging components increases, and their positions differ. This allows multiple charging components to limit the movement of the earphone 200 within the contoured groove 21 during insertion, effectively ensuring electrical contact between the earphone 200 and the charging component in the contoured groove 21, thus reducing the likelihood of poor charging contact in the earphone case 100.
[0042] In some embodiments of this application, the cover 10 is provided with an abutment portion. When the headphone case 100 is closed, the abutment portion abuts against at least a portion of the headphone 200, and there is an action force between the abutment portion and the headphone 200, thereby pressing the headphone 200 into the contour groove 21 and preventing the headphone 200 from shaking in the contour groove 21, so as to improve the stability of the headphone 200 placed in the headphone case 100 and reduce the possibility of poor charging contact of the headphone 200 in the headphone case 100.
[0043] In some embodiments of this application, the earphone case 100 further includes a first suction member (not shown in the figure), which is disposed within the contoured groove 21. The first suction member is used to suction the earphone 200. It is understood that the first suction member makes the earphone 200 more stable in the earphone case 100, reducing the shaking of the earphone 200 within the contoured groove 21, thereby reducing the friction frequency between the earphone 200 and the inner wall of the contoured groove 21. A second suction member can be correspondingly disposed on the earphone 200 so that the first and second suction members can attract each other, further improving the stability of the earphone 200 in the contoured groove 21 and reducing the possibility of poor charging contact in the earphone case 100.
[0044] Please see Figure 4 In some embodiments of this application, the first sidewall 211 includes a first part 2111 and a second part 2112. The second part 2112 is located between the first part 2111 and the second sidewall 212. The first part 2111 is connected to the second sidewall 212 through the second part 2112. The second part 2112 is arranged in the form of an arc surface or an inclined surface. A second charging component 32 is provided on the second part 2112.
[0045] Specifically, the first part 2111 and the second sidewall 212 are transitioned by an arc surface or a slope to make the connection between the first part 2111 and the second sidewall 212 smoother, increasing the contact surface between the inner sidewall of the contour groove 21 and the earphone 200, thereby making the earphone 200 more stable in the contour groove 21.
[0046] Understandably, since the second part 2112 is an arc or inclined surface, it is not at the same height as the second sidewall 212. That is, the first charging component 31 and the second charging component 32 are at different heights. During the insertion of the earphone 200 into the contoured groove 21, the charging part 50 on the earphone 200 will first contact the second charging component 32, and then contact the first charging component 31. Simultaneously, the first part 2111 limits the movement of the earphone 200, preventing displacement and ensuring that the earphone 200 remains in electrical contact with the second charging component 32 on the second part 2112.
[0047] Similarly, such as Figure 4 As shown, the third sidewall 213 includes a third portion 2131 and a fourth portion 2132, with the fourth portion 2132 located between the third portion 2131 and the second sidewall 212. Figure 4 One dotted line represents the second part 2112, and the other dotted line represents the fourth part 2132. The third part 2131 is connected to the second sidewall 212 through the fourth part 2132. The fourth part 2132 is curved or inclined, and a second charging component 32 is provided on the fourth part 2132. Specifically, the third part 2131 and the second sidewall 212 are transitioned by a curved or inclined surface to make the connection between the third part 2131 and the second sidewall 212 smoother, increasing the contact surface between the inner sidewall of the contoured groove 21 and the earphone 200, thereby making the earphone 200 more stable in the contoured groove 21.
[0048] Understandably, since the fourth part 2132 is an arc or inclined surface, it is not at the same height as the second sidewall 212. That is, the first charging component 31 and the second charging component 32 are at different heights. During the insertion of the earphone 200 into the contoured groove 21, the charging part 50 on the earphone 200 will first contact the second charging component 32, and then contact the first charging component 31. Simultaneously, the third part 2131 limits the movement of the earphone 200, preventing displacement and ensuring that the earphone 200 remains in electrical contact with the second charging component 32 on the fourth part 2132.
[0049] In some embodiments, such as Figure 5 As shown, the second part 2112 and the fourth part 2132 are both provided with second charging components 32, so that charging components are provided on different side walls of the contoured groove 21. The number of charging components is large and the positions are different. In this way, when the earphone 200 is placed into the contoured groove 21, multiple charging components can jointly limit the earphone 200 and prevent the earphone 200 from moving inside the contoured groove 21. The earphone 200 maintains electrical contact with at least two charging components, so that the earphone 200 can be charged in the earphone case 100. This can effectively ensure that the earphone 200 is in electrical contact with the charging components in the contoured groove 21 and reduce the possibility of poor charging contact of the earphone 200 in the earphone case 100.
[0050] For further details, please see Figure 3 In some embodiments of this application, the housing 20 has a first side surface 22 for contacting the cover 10, and a contoured groove 21 is provided on the first side surface 22. The earphone case 100 also includes a circuit board 40, which is located below the second side wall 212 and disposed inside the housing 20. The circuit board 40 extends in a direction parallel to the first side surface 22, and the circuit board 40 is electrically connected to the first charging component 31 and the second charging component 32.
[0051] Specifically, the circuit board 40 is parallel to the first side 22. The bottoms of the first charging component 31 and the second charging component 32 both extend onto the circuit board 40 and are electrically connected to the circuit board 40. The top of the first charging component 31 extends from the second side wall 212 of the contour groove 21, and the top of the second charging component 32 extends from the second part 2112 and / or the fourth part 2132 of the contour groove 21. Therefore, the lengths of the first charging component 31 and the second charging component 32 are different.
[0052] For further details, please see Figure 4 In some embodiments of this application, the second sidewall 212 is inclined along the direction from the first sidewall 211 to the third sidewall 213 so that the earphone 200 is in an inclined position when stored.
[0053] Specifically, taking the second sidewall 212 extending obliquely upward from the first sidewall 211 to the third sidewall 213 as an example (i.e., Figure 4 The dotted line on the left is the second part 2112, and the dotted line on the right is the fourth part 2132. At this time, the bottom height of the first sidewall 211 is lower than the bottom height of the third sidewall 213. Since the second sidewall 212 is a slope, when the earphone 200 is stored in the contour groove 21, most of the weight of the earphone 200 falls between the first sidewall 211 and the second sidewall 212 under the action of gravity. Therefore, the earphone 200 is difficult to move between the first sidewall 211 and the third sidewall 213, thereby further limiting the earphone 200 and preventing the earphone 200 from being displaced in the contour groove 21.
[0054] For further details, please continue reading. Figure 4 In some embodiments of this application, the second sidewall 212 extends obliquely upward from the first sidewall 211 to the third sidewall 213. The second sidewall 212 is an inclined surface, so the second sidewall 212 has a higher top position and a lower bottom position. At this time, the second part 2112 of the first sidewall 211 is connected to the bottom end of the inclined surface of the second sidewall 212, and the fourth part 2132 of the third sidewall 213 is connected to the top end of the inclined surface of the second sidewall 212. The first charging component 31 is disposed near the bottom end of the inclined surface of the second sidewall 212, and the second charging component 32 is disposed on the side of the second part 2112 near the bottom end of the inclined surface of the second sidewall 212.
[0055] It is understandable that the second sidewall 212 extends upwards at an angle from the first sidewall 211 to the third sidewall 213. Therefore, the groove depth is different at different positions in the contoured groove 21. The groove depth near the first sidewall 211 is greater than the groove depth near the third sidewall 213. The first charging component 31 and the second charging component 32 are both located at the positions with greater groove depth in the contoured groove 21. This allows the earphone 200 to make more stable contact with the first charging component 31 and the second charging component 32 under the action of gravity when the earphone 200 is placed, reducing the possibility of poor contact between the earphone 200 and the first charging component 31 and the second charging component 32.
[0056] In some embodiments of this application, the second charging component 32 is provided with a guide slope (not shown in the figure). The guide slope is used to contact the earphone 200. When the earphone 200 is placed, the guide slope on the second charging component 32 can contact the earphone 200, which is beneficial for the earphone 200 to push the second charging component 32 into the first side wall 211 through the guide slope.
[0057] For example, the second charging component 32 is a charging probe, which is located on the first sidewall 211 of the contoured groove 21. The guide slope is disposed at the end of the charging probe away from the first sidewall 211 and is arranged around the circumference of the charging probe, so that the earphone 200 can better contact the guide slope.
[0058] like Figure 6 As shown, the earphone 200 includes an ear hook 60 and a sound-emitting part 70 connected to each other. The sound-emitting part 70 is used to be worn in the concha of the user's ear. The ear hook 60 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.
[0059] In some embodiments of this application, such as Figure 6 As shown, the housing 20 has a first side surface 22 for contacting the cover 10. A contoured groove 21 is provided on the first side surface 22. The contoured groove 21 has a first recess 214 and a second recess 215. The first side wall 211, the second side wall 212 and the third side wall 213 are arranged together to form the first recess 214. The first recess 214 is used to place the sound-emitting part 70. The acoustic components and circuit components in the earphone 200 are all arranged in the sound-emitting part 70. Therefore, the charging component 30 is arranged in the first recess 214 to be electrically connected to the circuit components in the sound-emitting part 70.
[0060] The second recess 215 is connected to the first recess 214. The orthographic projection of the second recess 215 on the first side 22 is arc-shaped. The second recess 215 is used to place the ear hook 60, thereby making the overall shape of the second recess 215 match the shape of the ear hook 60, thus reducing the wear of the inner wall of the second recess 215 on the ear hook 60.
[0061] Specifically, the inner wall of the second recess 215 is a curved surface that matches the shape of the ear hook. When the earphone 200 is placed in the second recess 215, the surface of the ear hook 60 is in contact with the curved inner wall of the second recess 215. The curved shape of the inner wall of the second recess 215 is more compatible with the shape of the ear hook 60. When the ear hook 60 is placed in the second recess 215, it can improve the pressure deformation of the shape of the ear hook 60 caused by the inner wall of the second recess 215, and reduce the friction between the second recess 215 and the ear hook 60, thereby further reducing the wear of the ear hook 60 by the inner wall of the second recess 215.
