[0002] With the development of society, audio devices are increasingly favored by consumers. Audio devices can be applied in offices, daily life, or daily travel so that users can connect them to electronic devices to achieve functions such as remote work, video viewing, gaming, music listening, and voice calls.

[0003] In order to avoid the noise generated by the external speaker of the audio device affecting others in public places or offices, users usually use headphones in combination with the audio device. With the progress of technology, Bluetooth headphones are deeply loved by people because of their advantages such as no wire entanglement. Bluetooth headphones are usually used in combination with a headphone box. When not in use, the Bluetooth headphones are placed in the headphone box, and when in use, the Bluetooth headphones are taken out of the headphone box for wearing. In addition, the headphone box also serves as a portable mobile power supply. When charging, just put the Bluetooth headphones into the corresponding headphone slot.

[0004] However, when carrying the headphone box out, the Bluetooth headphones placed in the headphone box are prone to shift under frequent vibration, and collide with the headphone box to form abnormal noises, and even cause the charging contacts not to be fully contacted or poorly contacted, affecting the charging and the user experience.

[0049] The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0050] The present disclosure provides a storage box, which includes an upper shell and a lower shell, wherein the upper shell and the lower shell jointly enclose a receiving cavity for the received object, and the lower shell is provided with a mounting groove; characterized in that the storage box further includes: a first limiting portion, which is arranged on the inner surface of the upper shell opposite to the lower shell and protrudes towards the lower shell; and the first limiting portion is arranged adjacent to a first part of the mounting groove, and the first limiting portion and the first part of the mounting groove form a first limiting area; and a second limiting portion, which is arranged on the inner surface of the upper shell facing the receiving cavity, and the second limiting portion is a plane or an arc surface; and the second limiting portion is arranged opposite to a second part of the mounting groove, and the second limiting portion and the second part of the mounting groove form a second limiting area; the first limiting area and the second limiting area jointly form a limiting cavity for the received object.

[0051] The storage box in the present disclosure has a limiting cavity for the earphone jointly formed by the first limiting area and the second limiting area. This limiting cavity can better limit the received object inside the storage box and prevent the received object from shaking and colliding in the storage box.

[0052] In some embodiments, the present disclosure provides an earphone box, which includes the above-mentioned storage box, and this storage box is used for storing earphones.

[0053] Next, taking the earphone box as an example, the limiting cavity inside the storage box will be introduced in detail.

[0054] The earphone case 100 in this disclosure includes an upper shell 101 and a lower shell 102. The lower shell 102 is provided with a mounting groove adapted to the shape of the earphone, and the upper shell 101 is provided with a limiting portion for limiting the earphone. After the earphone is placed in the mounting groove, the upper shell 101 and the lower shell 102 are covered together. The limiting portion on the upper shell 101 and the mounting groove on the lower shell 102 jointly limit the earphone, so that the earphone is fixed in the accommodation cavity and prevented from being displaced and shaken in the earphone case 100.

[0055] As Figure 1 As shown in the schematic diagram of the earphone case, both the upper shell 101 and the lower shell 102 of the earphone case 100 provided in this disclosure are open structures, and the two jointly enclose an accommodation cavity for accommodating the earphone. Specifically, the earphone case 100 in this disclosure has a certain extension length. The upper shell 101 and the lower shell 102 are rotatably connected by a rotating shaft provided on the first side in the extension length direction, and the second side opposite to the first side is the opening and closing area. When in use, the upper shell 101 in the opening and closing area rotates along the rotating shaft to open or close the earphone case 100.

[0056] In the solution of this disclosure, the side where the opening and closing area is located is the main viewing area, the side where the rotating shaft is located is the rear viewing area, and the two end portions of the left and right of the earphone case are the left viewing area and the right viewing area respectively.

[0057] To facilitate the understanding of the solution of this disclosure, the mounting groove in this solution will be introduced below.

[0058] As Figure 4 As shown in the schematic diagram of the lower shell of the earphone case, the mounting groove includes a body part groove for accommodating the earphone body, an earhook groove 1023 for accommodating the earhook, and a battery part groove 1024 for accommodating the battery part, which are connected in sequence. The body part groove includes a sounding part groove 1021 and a connecting part groove 1022 connected in sequence, and the connecting part groove 1022 is connected to one end of the earhook groove.

[0059] The mounting grooves in this disclosure include a first mounting groove and a second mounting groove symmetrically arranged along a first axis, where the first axis is the perpendicular bisector of the two ends of the earphone case 100 in its length direction. Next, the first mounting groove on the left side will be taken as an example for introduction. The main body part groove is arranged in the middle area and extends obliquely towards the second side position near the left end area, and its extended end is connected to the ear hook groove 1023. The ear hook groove 1023 first extends from the second side towards the first side, and then extends obliquely towards the position of the first axis close to the first side, and its extended end is connected to the battery part groove 1024. The battery part groove 1024 continues to extend towards the position of the first axis close to the first side. Similarly, the second mounting groove is symmetrically arranged with the first mounting groove along the first axis, and the difference between it and the first mounting groove is that the main body part groove of the second mounting groove extends towards the right side, and the rest of the extension directions are the same. It should be noted that the extension trajectories of the main body part groove and the battery part groove 1024 are linear, and the extension trajectory of the ear hook groove 1023 is arc-shaped.

[0060] In the solution of this disclosure, the earphone case has two independent cavities symmetrically arranged along a first axis of symmetry, and the first mounting groove and the second mounting groove are respectively located in the two independent cavities. Also, based on the setting form of the mounting grooves in this solution, when the user uses it, the opening and closing part of the earphone case faces the human body, and the rotating shaft is on the side away from the human body. At this time, the first mounting groove on the left corresponds to the user's left hand side, the second mounting groove on the right corresponds to the user's right hand side, and the left earphone is placed in the first mounting groove, and the right earphone is placed in the second mounting groove.

[0061] When the user wears the earphone with either hand, the user pinches the main body part to take out the earphone from the earphone case, and then moves the sounding part towards the human ear direction. When it reaches the human ear position, after hanging the ear hook above the human ear, fix the sounding part of the earphone in the concha, and then press down the wrist or lift the elbow to tilt the connecting part of the earphone through the area between the helix and the tragus of the human ear to complete the wearing. Therefore, in the solution of this disclosure, on the basis of setting the battery part groove close to the first axis and setting the main body part groove away from the first axis relative to the battery part groove, the ear hook is also set close to the rotating shaft side, and the main body part is set close to the opening and closing part side, so that the earphone does not need to change hands during the wearing process, nor does it need to take out the earphone and use the other hand to assist in adjusting the direction before wearing. This solution can be completed with one hand. In addition, in this solution, the direction towards which the sounding part of the earphone faces is the same as the direction towards which the palm faces, and the left side corresponds to the left ear and the right side corresponds to the right ear, making it convenient to pick up and place, and facilitating the user to wear the earphone with one hand.

[0062] In addition, the earphone in this disclosure is not a planar structure in its thickness direction. To better limit the position of the earphone, the depths of various parts of the mounting groove are not the same. Specifically, the depth of the middle area of the earhook groove is greater than the depth of the sound generating part groove 1021, the depth of the sound generating part groove 1021 is greater than the depth of the connecting part groove 1022. The depth of the area of the earhook groove close to the connecting part groove 1022 is greater than the depth of the connecting part groove 1022, and the depth of the area of the earhook groove close to the battery part groove is less than the depth of the battery part groove. In this solution, the thickness direction of the earphone body refers to the direction of approaching or moving away from the human ear when the earphone is in a worn state.

[0063] To facilitate the understanding of the solution of this disclosure, the reasons for the different depths of the mounting groove are introduced in detail below. The earphone in this disclosure is an open earphone. When in use, the user fixes the earphone 200 on the human ear through the earhook, and the human ear usually extends obliquely outward relative to the side of the head, forming an angle with the head. In order to better fit the human ear, the earhook is obliquely arranged relative to the earphone body. That is to say, the earhook has an inclination relative to the thickness direction of the earphone body, and this inclination tends to be the same as the angle formed between the human ear and the head. And in order to better place the earhook in the earhook groove, the depth of the middle area of the earhook groove is set to be the deepest.

[0064] Since the earphone body part includes a sound generating part and a connecting part, the lower surface of the sound generating part close to the ear canal protrudes from the lower surface of the connecting part close to the ear canal. Therefore, the depth of the sound generating part groove 1021 for accommodating the sound generating part is greater than the depth of the connecting part groove 1022 for accommodating the connecting part.

[0065] Also, one end of the earhook is connected to the connecting part, and the other end is connected to the battery part. When the earphone is in a worn state, the end of the earhook connected to the connecting part is located in the area of the human ear close to the face. Therefore, the earhook at this position extends obliquely towards the lower surface of the earphone body, and the middle area extends obliquely towards the upper surface of the earphone body, and its extending end is connected to the battery part. And the upper end of the battery part away from the ear canal direction is slightly lower than the upper end of the connecting part or almost flush with the upper end of the connecting part. Therefore, the depth of the battery part groove is slightly less than the depth of the sound generating part groove 1021 or the same as the depth of the sound generating part groove 1021. The depth of the area of the earhook groove close to the connecting part groove 1022 is greater than the depth of the connecting part groove 1022, and the depth of the earhook groove close to the battery groove is less than the depth of the battery part groove.

[0066] In the solution of this disclosure, a battery is provided in the earphone case, and the battery is specifically arranged in the middle area inside the lower shell of the earphone case. Specifically, as Figure 4As shown in the schematic diagram of the lower shell of the earphone case, in this solution, the depth of the middle area of the ear hook groove 1023 is the largest, and the middle area of the ear hook groove 1023 is located at both ends of the earphone case. Through such a depth design, the depth of the installation groove in the middle area of the earphone case is relatively shallow. Therefore, there is enough space below this area to accommodate the battery. As a result, the battery in the lower shell of the earphone case can be made thicker as a single unit, and there is no need to cut the battery into two pieces and install them separately below the first installation groove and the second installation groove. It only needs to be made into a whole piece and installed between the two ear hook grooves. Through this design, when manufacturing the earphone case, the battery capacity can be increased and the stacking design can be simplified.

[0067] As Figure 3 As shown in the schematic diagram of the inner surface of the earphone case, in one embodiment, the limiting parts on the upper shell 101 for limiting the earphone include a first limiting part 1011 and a second limiting part 1012. The first limiting part 1011 extends from the inner surface of the upper shell 101 towards the lower shell 102. That is to say, the first limiting part 1011 is a convex structure arranged on the inner surface of the upper shell 101. This convex structure is arranged on the first axis and is symmetrically arranged along the first axis. Since the battery part grooves 1024 in the first installation groove and the second installation groove are relatively and obliquely arranged in this disclosure, two battery part grooves 1024 form a V-shaped area 1026 with an opening facing the second side. When the upper shell 101 and the lower shell 102 are in the closed state, the projected part of the first limiting part 1011 on the lower shell 102 falls into the V-shaped area 1026 and part of it falls into the battery part groove 1024. The projection of the first limiting part 1011 in the battery part groove 1024 is the first part, and the first part and the first limiting part 1011 arranged above it together constitute the first limiting area. Also, since the projection of the first limiting part 1011 falls into the battery part groove 1024 of the first installation groove and the battery part groove 1024 of the second installation groove at the same time, the first limiting part 1011 and the first parts of the two battery part grooves 1024 together constitute two first limiting areas.

[0068] In the above solution, the second limiting part 1012 is also arranged on the inner surface of the upper shell 101 facing the accommodation cavity, and the second limiting part is a plane or a curved surface. The second limiting part 1012 is arranged opposite to the second part of the installation groove, and the second limiting part 1012 and the second part constitute the second limiting area. In one embodiment of this solution, the second part of the installation groove refers to the area where the positive projection of the main body part groove of the earphone on the inner surface of the upper shell is located. The main body part groove and the second limiting part 1012 constitute the second limiting area. When the earphone is installed in the installation groove and the upper shell and the lower shell are in the closed state, the top surface of the earphone main body abuts against the second limiting part 1012 on the inner surface of the upper shell, so that the second limiting part and the main body part groove jointly limit the earphone.

[0069] In another embodiment of this solution, when the earphone is installed in the installation groove, the plane where the top surface of the earphone body is located is coplanar with the plane where the uppermost end of the battery part is located. In this embodiment, the second part of the installation groove refers to the area where the orthographic projections of the body part groove and the battery part groove on the inner surface of the upper shell are located. The body part groove and its projection, and the battery part groove and its projection together form the second limiting area. When the upper shell and the lower shell are in the closed state, the top surface of the earphone body part abuts against the inner surface of the upper shell, and the uppermost end of the battery part abuts against the inner surface of the upper shell. That is to say, the second limiting area limits the two ends of the earphone, namely the body part and the battery part. In this solution, since the middle area of the earhook is completely located in the earhook groove, mainly limiting the two ends of the earphone can achieve the overall limiting of the earphone.

[0070] In another embodiment, the setting position of the first limiting part 1011 is different from the setting position in the above solution. In this solution, the projection of the first limiting part 1011 on the lower shell 102 only falls into the V-shaped area 1026, and the outermost side of this projection is located at the side wall of the battery part groove 1024. In this solution, whether the lower end of the first limiting part 1011 on the upper shell 101 abuts against the surface of the V-shaped area 1026 or has a certain distance can achieve the limiting of the earphone.

[0071] In the above solution, when the earphone is installed in the battery part groove, at least fifty percent of its volume is located outside the battery part groove. Therefore, when the first limiting part 1011 abuts against the outer surface of the battery part at the horizontal central axis, the first limiting part 1011 can limit the battery part in the horizontal direction. When the first limiting part 1011 abuts against the outer surface of the battery part above the horizontal central axis, the first limiting part 1011 can limit the battery part obliquely downward.

[0072] The second limiting area in this disclosure can limit the earphone in the vertical direction and can also limit the earphone in the horizontal direction. On this basis, a first limiting area is also set. This first limiting area can limit the earphone in the horizontal direction and can also limit the earphone in other directions, so that the earphone in this solution can be more firmly limited in the limiting cavity, avoiding the displacement of the earphone in the earphone box 100 and affecting its charging.

[0073] In the solution of this disclosure, in order to provide a better visual effect for users, the upper shell 101 of the earphone box 100 is set as a transparent shell or a translucent shell, so that users can observe the earphone through the upper shell 101 without opening the earphone box 100.

[0074] Of course, in other solutions, a part of the lower housing of the earphone case can also be set as a transparent or semi-transparent housing. For example, the housings at both ends in the length direction of the earphone case are transparent housings, so that the user can further see more parts of the earphone through the housing.

[0075] In the solution disclosed herein, the earphone includes a body part and a battery part, wherein the first limiting area limits the battery part, and the second limiting area limits the body part; the battery part includes a cylindrical housing, and a part of the outer surface of the housing abuts against the first part of the mounting groove; and the outer surface of the housing is tangent to the curved surface of the first limiting part, or the shortest distance between the outer surface of the housing and the curved surface of the first limiting part is 0.2-0.5 mm.

[0076] In the above solution, since there is a certain distance between the outer surface of the first limiting part and the housing of the battery part, tolerances can be accommodated, and touches can be reduced to avoid scratching the earphone.

[0077] In one embodiment, the earphone compatible with the earphone case 100 in this solution is an open earphone, which includes an earphone body, an earhook and a battery part connected in sequence. The battery part at least includes a battery and a cylindrical housing arranged on the outer periphery of the battery, and the first limiting part 1011 on the upper housing 101 has a curved surface convex structure on the outer surface. When the earphone is placed in the mounting groove and the upper housing 101 and the lower housing 102 are in a closed state, the outer surface of the housing of the battery part is tangent to the curved surface of the first limiting part 1011, that is, the first limiting part 1011 abuts against the battery part to limit it, so as to prevent the displacement of the battery part from affecting charging.

[0078] As Figure 5 As shown in the cross-sectional view of the earphone case in the vertical direction of the upper housing and the lower housing, in another embodiment, the peripheral surface of the battery part does not abut against the curved surface of the first limiting part 1011, but has a gap with the first limiting part 1011. Specifically, the shortest distance between the peripheral surface of the battery part and the curved surface of the first limiting part 1011 is 0.2-0.5 mm. Since there is a margin space between the charging positions of the earphone, the offset of the earphone within this margin space will not affect charging. Therefore, the distance between the battery part and the first limiting part 1011 is set to 0.2-0.5 mm, so that the first limiting part 1011 can limit the offset of the battery part within a certain range and does not affect charging.

[0079] In a specific implementation scheme, the distance between the peripheral surface of the battery part and the curved surface of the first limiting part is 0.3 mm. Of course, in other specific implementation schemes, this distance can also be other values between 0.2-0.5 mm.

[0080] In the disclosed solution, the first retaining portion is made of a transparent material, and its surface does not abut the battery. This arrangement effectively reduces the contact area between the earphones and the first retaining portion, reduces scratches on the inside, and improves the durability of the first retaining portion. Furthermore, the upper shell of the earphone case is transparent, allowing the earphone details to be clearly displayed on the exterior surface.

[0081] Furthermore, when the earphones are placed in the earphone case, the battery portion contacts the first retaining portion as the case shakes. Since force transmission doesn't require contact across the entire surface, this solution provides a curved outer surface for the first retaining portion. This allows the earphones to be retained in position through point or line contact. This convex curved surface reduces the volume of the first retaining portion compared to a cylindrical shape, thereby saving material.

[0082] In the solution disclosed herein, when the upper shell 101 and the lower shell 102 are in a covered state, the first limiting portion 1011 abuts against the inner surface opposite to the lower shell 102; or the distance between the first limiting portion 1011 and the inner surface opposite to the lower shell 102 is 4-6 mm.

[0083] In this solution, when the projection of the first limiting portion 1011 on the lower shell 102 only falls into the V-shaped area 1026, the first limiting portion 1011 can either abut or not abut the surface in the V-shaped area 1026 on the lower shell 102. Specifically, in one embodiment, the extension length of the first limiting portion 1011 is relatively long. When the upper shell 101 and the lower shell 102 are in the closed state, the lower end of the first limiting portion 1011 abuts the inner surface of the lower shell 102. The first limiting portion can play a role in supporting the upper shell, so that the upper shell is not easy to collapse when pressed. In another embodiment, in order to save material, the extension length of the first limiting portion 1011 does not need to be set very long. That is, when the upper shell 101 and the lower shell 102 are in the closed state, the lower end of the first limiting portion 1011 does not need to abut the inner surface of the lower shell 102, but has a certain distance between the inner surface of the lower shell 102, and the distance can be 4-6 mm.

[0084] In a specific embodiment, the distance between the first limiting portion and the inner surface of the lower housing is 5 mm. Of course, in other specific embodiments, the distance can also be other values between 4-6 mm.

[0085] In this solution, since there is a distance between the first limiting part and the lower shell, that is, the protrusion of the first limiting part will not be too much, it can reduce the stress risk generated by the first limiting part during special-shaped injection molding during the production process, and can also reduce the stress risk of the first limiting part after production is completed.

[0086] In this solution, since the battery part is provided protruding from the battery part groove 1024, the extending length of the first limiting part 1011 only needs to be able to abut against the battery part, and there is no need to extend to the position of the inner surface of the lower housing 102, and the battery part can still be limited.

[0087] In the solution disclosed herein, when the user places the earphone in the earphone case, in order to reduce the knocking or abnormal noise generated by contact when the earphone contacts the installation groove, flexible pads are provided at the bottoms of the main body part groove and the battery part groove. In addition, the flexible pads can also accommodate the machining tolerances of the main body part groove and the battery part groove.

[0088] In the solution disclosed herein, the top surface of the main body part of the earphone is a flat surface, and the second limiting part 1012 is a flat surface. When the earphone case is in a closed state, the second limiting part 1012 abuts against the top surface, or the second limiting part is arranged parallel to the top surface, and the distance between the two is 0.2 - 0.5 mm.

[0089] In a specific embodiment, the top surface of the main body part of the earphone is a flat surface. The top surface of the main body part refers to the upper surface of the main body part, and the side opposite to the upper surface of the main body part is the lower surface. When the earphone is installed in the earphone case, the lower surface abuts against the main body part groove, and the upper surface abuts against the second limiting part for limiting or does not abut against the second limiting part for limiting. When the upper surface of the main body part does not abut against the second limiting part, the distance between the two is 0.2 - 0.5 mm.

[0090] In the solution disclosed herein, the top surface of the main body part of the earphone is a flat surface; the second limiting part is an arc surface. When the earphone case is in a closed state, the arc surface abuts against the top surface, or the distance between the two is 0.2 - 0.5 mm.

[0091] In a specific embodiment, the second limiting part may not be a flat surface but an arc surface, and the arc surface protrudes towards the lower housing. When the earphone is installed in the earphone case, the arc surface abuts against the upper surface of the main body part, and the two limit the main body part through point contact or line contact. Or when the earphone is installed in the earphone case, the arc surface does not abut against the upper surface of the main body part, and the distance between the two is any value within 0.2 - 0.5 mm.

[0092] In the above solution, since there is a certain distance between the arc-shaped upper surface or the flat upper surface of the main body part and the second limiting part, the tolerance can be accommodated, and the knocking and abnormal noise generated by knocking of the earphone can be effectively reduced.

[0093] In the solution disclosed herein, on the outer surface of the upper housing, at a position opposite to the first limiting portion, a recess is provided, and the recess extends in the direction of the accommodating cavity; the first limiting portion constitutes a first curved surface, the recess constitutes a second curved surface, and the first curved surface and the second curved surface are coaxially arranged; the curvature of the first curved surface is smaller than the curvature of the second curved surface, forming a lens.

[0094] As Figure 2 As shown in the top view of the earphone case, in the above solution, the first limiting portion extends by being recessed from the outer surface of the upper housing towards the inner surface and protrudes from the inner surface. That is to say, the outer surface of the first limiting portion is not a plane, and there is a recessed area in the middle area thereof, and the recessed area is correspondingly arranged with the first limiting portion. In the solution of the present disclosure, since a recess is provided on the upper surface of the upper housing, the user can distinguish the upper housing from the lower housing through the sense of touch.

[0095] Specifically, the first limiting portion constitutes a first curved surface, and the recess constitutes a second curved surface, wherein the first curved surface and the second curved surface are coaxially arranged. In a specific solution, the curvature of the first curved surface is smaller than the curvature of the second curved surface, that is to say, the protruding height of the first curved surface is greater than the protruding height of the second curved surface, that is, the center of the upper housing is the thickest, and the recess and the first limiting portion form a lens. Also, since the upper housing is made of a transparent material, a special visual effect will be formed at the recess.

[0096] Those skilled in the art can understand that, according to different design requirements, the curvature of the first curved surface can also be set to be equal to or greater than the curvature of the second curved surface.

[0097] In addition, in other solutions, the outer surface of the upper housing can be a plane, and the first limiting portion protrudes from the inner surface of the upper housing.

[0098] In the solution disclosed herein: a stop portion is provided on the lower housing 102, the stop portion is provided at a position on the side wall of the battery portion groove 1024 opposite to the first portion and away from the first limiting portion, and the stop portion, the battery portion groove, and the first limiting portion together constitute a third limiting area for restricting the cylindrical surface of the battery portion.

[0099] As Figure 4As shown in the schematic diagram of the inner surface of the lower housing, in a specific solution, in order to further limit the earphone, a stop portion is further provided on the lower housing 102. Specifically, the stop portion 1025 is provided on the side wall of the battery portion groove 1024 away from the first limiting portion. More specifically, the stop portion 1025 is a plate-like structure extending upward in the direction of the upper housing 101 from the side wall position opposite to the side wall forming the V-shaped region 1026. That is to say, the stop portion 1025 and the first limiting portion are respectively provided on both sides of the battery portion groove and are oppositely arranged. When the earphone is placed in the installation groove and the earphone box is in the closed state, the stop portion abuts against the outer peripheral surface of the battery portion and a first support point is formed therebetween, and the outer peripheral surface of the battery portion abuts against the first limiting portion and a second support point is formed therebetween. The connection line of the first support point and the second support point can be arranged parallel to the upper surface of the main body portion, or can extend obliquely upward in the direction of the inner surface of the upper housing. In addition, the surface of the battery portion in contact with the lowest end of the battery portion groove is respectively connected to the first support point and the second support point, and the three form a triangle. That is to say, the stop portion, the battery portion groove and the first limiting portion jointly constitute a third limiting area for limiting the cylindrical surface of the battery portion. In this solution, due to the setting of the stop portion, the limiting effect on the battery portion is further improved.

[0100] In a specific implementation, the stop portion 1025 extends from the side wall position of the battery portion groove in the direction of the inner surface of the upper housing, and its extending end does not abut against the inner surface of the upper housing 101.

[0101] In another specific implementation, the stop portion 1025 extends from the side wall position of the battery portion groove in the direction of the inner surface of the upper housing, and its extending end is flush with the axial section of the battery portion.

[0102] In the above solution, since the installation groove includes a first installation groove and a second installation groove, two stop portions 1025 are provided on the lower housing 102. When in use, when the earphone is installed in the earphone box 100, the first limiting portion 1011 and the stop portion 1025 respectively clamp both ends of the battery portion to limit the battery portion, and this solution further improves the limiting effect on the earphone in the horizontal direction.

[0103] In the solution disclosed herein, in order to increase the functionality of the stop portion, a functional member is provided on the stop portion. For example, the functional member can be a sensor or a charging contact. When in use, the sensor can detect whether the earphone is installed in place, and the charging contact can charge the battery on the earphone.

[0104] In some specific solutions, in order to better limit the earphone body part, a first magnetic part is provided in the sound - emitting part groove 1021 or the connecting part groove 1022, and the body part is fixed by magnetic attraction with the first magnetic part. Of course, in order to better limit the body part, first magnetic parts are provided in both the sound - emitting part groove 1021 and the connecting part groove 1022, and are respectively fixed by magnetic attraction with their corresponding sound - emitting parts and connecting parts.

[0105] Those skilled in the art can understand that, in order to further limit the battery part, a magnetic part is provided inside the stop part 1025, or a second magnetic part is provided in the battery part groove 1024, and the second magnetic part is magnetically connected to the battery part to further limit the battery part of the earphone.

[0106] In some specific solutions, in order to further limit other components except the battery part in the horizontal direction, a plurality of first limiting parts 1011 are provided on the inner surface of the upper shell 101, and the plurality of first limiting parts 1011 form a plurality of positioning points or positioning lines, and the plurality of positioning points or positioning lines are in point - contact or line - contact with the earphone body part or the earhook to limit the body part or the earhook. Since the upper shell 101 in this solution is a transparent shell, the first limiting parts 1011 are also set as transparent parts. Therefore, the plurality of first limiting parts 1011 on the upper shell can form a plurality of magnifying glass effects, making it easier for users to see the local structure of the earphone.

[0107] In the above - mentioned solution, the structures of the plurality of first limiting parts 1011 can be the same or different. For example, the first limiting part 1011 can be a cylindrical structure, a hemispherical structure, or a plate - like structure.

[0108] Those skilled in the art can understand that, in order to better limit the earphone, the first limiting parts 1011 can be symmetrically arranged on both sides of the body part groove or the earhook groove 1023.

[0109] In the solution provided in this embodiment, due to the common cooperation of the first limiting part, the second limiting part, and the stop part, the earphone can be better limited in the accommodating cavity, preventing its displacement from affecting charging.

[0110] The above content has introduced in detail the limiting structure inside the earphone box. Next, the structure of the earphone box will be introduced in detail.

[0111] As Figure 1 As shown in the schematic diagram of the earphone box, the disclosed earphone box has a certain extended length. The upper shell 101 and the lower shell 102 are rotationally connected by a rotating shaft provided on the first side in the extended length direction. At the position of the second side opposite to the first side, the upper shell 101 and the lower shell 102 form an opening - closing area, and on the opening - closing area, the upper shell 101 rotates along the rotating shaft to open or close the earphone box.

[0112] In the solution disclosed herein, the outer surfaces of the upper housing 101 and the lower housing 102 at the opening / closing area both converge towards the joint surface, thereby forming a groove 103. Additionally, catches are provided on the upper housing 101 and the lower housing 102 at the opening / closing area. When the upper housing 101 and the lower housing 102 are in the closed state, the catches cooperate to lock the two together.

[0113] The upper housing 101 and the lower housing 102 have a certain thickness. The outer surfaces of the upper housing 101 and the lower housing 102 at the opening / closing area converge towards the joint surface, that is, the thickness of the upper housing 101 and the lower housing 102 at the opening / closing area gradually thins to form a groove. Of course, in other solutions, the thickness of the upper housing 101 and the lower housing 102 at the opening / closing area does not change, and only the extension direction is changed, that is, the side walls extend towards the accommodation cavity to form a groove 103.

[0114] During use, when closing the earphone case, rotate the upper housing 101 or the lower housing 102 along the rotating shaft to close the two together, and then lock the two together through the cooperation of the catch structure. When opening the earphone case, only place the hand at the groove 103 and apply a force in the direction away from the lower housing 102 to the upper housing 101 to open the catch, and then rotate the upper housing 101 along the rotating shaft in the direction away from the lower housing 102 to open the earphone case.

[0115] For the earphone case provided in this disclosure, the groove 103 is provided in the opening / closing area, and the opening / closing area substantially refers to the side wall on the opposite side of the rotating shaft. Also, since the earphone case of this disclosure has a certain extension length and the extension length of the groove 103 is also relatively long, when the user is using it, the hand can be placed in any area of the groove 103 to open the earphone case, and the operation is more convenient.

[0116] In the solution disclosed herein, the area where the groove is located is the opening / closing part. The opening / closing part is the area between the outermost ends where the end parts of the upper housing 101 and the lower housing 102 extend along the outer surface of the groove in the direction away from the accommodation cavity; at any position of the opening / closing part, the tangent line or the connection line between any position of the opening / closing part and the end part forms an angle with the joint surface that is less than or equal to 90°.

[0117] As Figure 6 shown in the left view of the earphone case and Figure 7 the right view of the earphone case, in a specific embodiment, there is an opening / closing part at the opening / closing area. The opening / closing part refers to the area where the groove is located, that is Figure 6The area marked by the dashed line box in the figure. Specifically, the opening and closing part refers to the area between the farthest points where the end of the upper housing 101 extends along the outer surface of the side wall of the upper housing 101 away from the accommodation cavity, and the area between the farthest points where the end of the lower housing 102 extends along the outer surface of the side wall of the lower housing 102 away from the accommodation cavity. In this solution, the side walls of the upper housing 101 and the lower housing 102 at the opening and closing part are inclined planes or curved surfaces. When the side wall at the opening and closing part is an inclined plane, the angle between the inclined plane and the extension line of the joint surface away from the accommodation cavity is less than or equal to 90°.

[0118] When the side wall at the opening and closing part is a curved surface, the angle between the tangent at any position of the curved surface or the connection line between any position of the curved surface and the end part and the extension line of the joint surface away from the accommodation cavity is α, and α is less than or equal to 90°. In this solution, the angle between the tangent at the extreme value of the outer surface of the side wall and the joint surface is 90°, and the angles between the tangents at other positions and the extension line of the joint surface away from the accommodation cavity are all less than 90°.

[0119] In the solution of the present disclosure, the outer surfaces of the side walls of the upper housing 101 and the lower housing 102 at the opening and closing area are arc-shaped, and are arc-transitionally connected to the outer top surfaces of the upper housing 101 and the lower housing 102 respectively; the groove is formed by splicing two arc surfaces of the adjacent first housing side wall and the second housing side wall; the outer surface contours of the upper housing and the lower housing are mirror-symmetrical at the end of the side edge. The inner surface of the top wall of the upper housing is parallel to the joint surface, and the inner surface of the side wall is perpendicular to the inner surface of the top wall. The vertical distance between the area of the outer surface of the side wall of the upper housing 101 farthest from the accommodation cavity and the plane of the joint surface is 3 - 5 mm, and the radius of the arc is 5 - 6 mm.

[0120] In the above solution, the outer surfaces of the upper housing 101 and the lower housing 102 are symmetrically arranged at the end of the side edge, and the outer surfaces of the side walls at the opening and closing area are arc-shaped. The groove is formed by the arc-shaped outer surface of the side wall extending towards the accommodation cavity, and the vertical distance between the highest point of the outer surface of the arc and the plane of the joint surface is 3 - 5 mm, and the radius of the arc is 5 - 6 mm.

[0121] In a specific implementation, the vertical distance between the highest point of the arc-shaped outer surface of the side wall of the upper housing and the plane of the joint surface is 4 mm, and the radius of the arc is 5.3 mm. Of course, in other implementations, the vertical distance between the highest point of the arc-shaped outer surface of the side wall of the upper housing and the plane of the joint surface is any value within 3 - 5 mm, and the radius of the arc is any value within 5 - 6 mm. And the depth of the groove at the opening and closing area is 1.5 - 3 mm, such as 1.8 mm. In this solution, the depth of the groove refers to the depth at which the arc surface retracts at the joint surface.

[0122] In the solution disclosed herein, the arc-shaped peripheral walls of the upper shell and the lower shell are set to the data described above, so that in addition to making the curved surface of the earphone case more beautiful, the depth of the groove at the opening and closing area is also more suitable for the user's finger to insert, and the upper shell and the lower shell are pressed during the insertion process, facilitating the opening of the earphone case with one hand.

[0123] In this solution, at least the inner surface of the top wall of the upper shell 101 and the lower shell 102 at the connection with the side wall at the opening and closing area is a plane, this plane is parallel to the joint surface, and the outer surface of the top wall is arc-transitionally connected to the outer surface of the side wall, and the inner surface of the top wall is vertically arranged with the inner surface of the side wall and the two are arc-transitionally connected.

[0124] In this solution, since the inner surface of the top wall is horizontally arranged, and the inner surface of the side wall is arranged perpendicular to the inner surface of the top wall, that is, the inner surface of the side wall is vertically arranged, this setting method is better for demolding in actual production and can improve production efficiency. In addition, the groove 103 is formed by the outer surfaces of the upper shell 101 and the lower shell 102 together, and the depth of the groove 103 is relatively large, enabling the user to more easily locate at the groove 103 and also making it possible for the user to open the earphone case with one hand. This solution can improve the user experience.

[0125] In another specific embodiment, the box body further includes a third side and a fourth side provided at both ends, and the opening and closing area extends from the second side to the third side and the fourth side. That is to say, in this embodiment, except for the side wall on the side where the rotating shaft is located which is not arc-shaped, the other three peripheral walls are all arc-shaped, that is, the second side, the third side and the fourth side are all opening and closing areas, and the user can also open the box body at the opening and closing areas of the third side and the fourth side. Based on the above content, those skilled in the art can understand that the opening and closing area can also be provided on the second side and the third side, or on the second side and the fourth side.

[0126] In another specific embodiment, the outer surfaces of the upper shell 101 and the lower shell 102 are symmetrically arranged along the ends of the side, and the outer surfaces of the upper shell 101 and the lower shell 102 are both arc-shaped. That is to say, in this solution, the outer surfaces of the peripheral walls of the upper shell 101 and the lower shell 102 are symmetrically arranged arcs. Such a setting not only enables the two shells to form a groove 103 at the opening and closing area, but also grooves 103 can be formed at the positions where the four peripheral walls of the upper shell 101 and the lower shell 102 abut.

[0127] In the above solution, the first housing is a transparent or translucent housing, and the outer surfaces of the first housing and the second housing are symmetrically arranged, that is, the outer surface contours of the first housing and the second housing are mirror-symmetrical at the end of the side edge. In addition, all the joints between the side walls and the top wall of the outer surface of the box disclosed in this disclosure are smooth arcs, that is, there are no sharp corners on the outer surface of the box, and the joints between the side walls and the joints between the side walls and the top wall are all arc-shaped. This can facilitate the placement of the box in a narrow space such as the pocket of clothes. When the box is placed in the pocket, the arc transition of the box makes the part where the pocket contacts the box have no obvious edges, and the pocket will support a trapezoid-like shape (for example Figure 7 the trapezoid shown by the dashed line box in

[0128] . The setting of the arc surface can reduce the trapezoid formed by the box supporting the pocket, and the volume is smaller in terms of physical feeling.

[0129] In the solution disclosed in this disclosure, the box is formed by injection molding or other methods, and this manufacturing method can reduce the stress concentration at the outer edge of the box.

[0130] In the above solution, the upper housing is a transparent or translucent housing, and the outer surfaces of the upper housing and the lower housing are symmetrically arranged, that is, the outer surface contours of the upper housing and the lower housing are mirror-symmetrical at the end of the side edge. In addition, all the joints between the side walls and the top wall of the outer surface of the earphone box disclosed in this disclosure are smooth arcs, that is, there are no sharp corners on the outer surface of the earphone box, and the joints between the side walls and the joints between the side walls and the top wall are all arc-shaped. This setting can prevent the sharp corners on the outer surface of the earphone box from colliding with other items when the earphone box and other items are placed together in the storage device, causing damage to the outer surface of other items. In addition, the arc-shaped setting makes the appearance of the earphone box more beautiful.

[0131] In another specific embodiment, except that there is no groove 103 on the side wall of the first side where the rotating shaft is located, the opening and closing area and the side parts of the two ends connected to the opening and closing area both have grooves 103. Through this setting method, users can quickly locate the opening and closing area through touch, so as to open or close the earphone box more quickly.

[0132] In the solution disclosed in this disclosure, the inner surface of the side wall of the upper housing 101 is a closed or unclosed smooth annular cylindrical surface; or the inner side surface of the upper housing 101 is a closed or unclosed smooth annular inclined surface, the inclined surface extends obliquely from the end to the top surface of the upper housing, and the included angle between the inclined surface and the joint surface is an acute angle; or the inner surface of the side wall of the upper housing 101 is a closed or unclosed smooth curved surface, and the curvature of the curved surface is the same as the curvature of the outer surface.

[0133] In a specific embodiment, the outer surface of the sidewall of the upper housing 101 is arc-shaped, the inner surface of the sidewall is vertically arranged, and the inner surface of the sidewall is perpendicular to the inner surface of the top wall of the upper housing 101, and the connection between the two is arc-shaped transition connection. In this solution, the upper housing 101 has four sidewalls, and the connections of the inner surfaces of the respective sidewalls are arc-shaped transition connections. When the inner surface of the sidewall does not need to avoid the rotating shaft, the inner surfaces of the four sidewalls of the upper housing 101 form a smooth and closed annular cylindrical surface. When the inner surface of the sidewall needs to avoid the rotating shaft, at this time, the inner surfaces of the four sidewalls form an unclosed annular cylindrical surface.

[0134] In the above solution, the upper housing 101 of the earphone case is provided as a transparent housing or a semi-transparent housing, so that the user can observe the state of the object placed in the accommodation cavity through the upper housing 101 without opening the earphone case. Also, since the outer surface of the sidewall of the upper housing 101 is arc-shaped, this setting method increases the thickness of the box body, makes the first housing 101 more robust, can withstand greater pressure formed from the top surface or side surface of the housing, and also improves the anti-drop performance.

[0135] Based on the fact that the outer surface of the sidewall of the upper housing 101 is arc-shaped, the inner surface is vertically arranged, so the outer surface and the inner surface of the sidewall form a plano-convex lens, and this lens can magnify the items placed in the earphone case, presenting a clearer visual effect to the user. In addition, when the sidewalls of the first side and the second side both form plano-convex lenses, a complex visual effect can be formed.

[0136] As Figure 8 As shown in the schematic diagram of the inner surface of the sidewall of the upper housing being an inclined surface, in another specific embodiment, the inner surface of the sidewall of the upper housing 101 is not vertically arranged, but is inclined. Specifically, the inner surface of the upper housing 101 extends from the end at its opening obliquely away from the central axis of the accommodation cavity to the top surface of the upper housing 101, and the angle between this inclined surface and the extension line of the joint surface away from the accommodation cavity is β, and this β is an acute angle. Of course, in this solution, the inner surfaces of the sidewalls and the inner surface of the top wall are also arc-transition connections. When the inner surface of the sidewall does not need to avoid the rotating shaft, the inner surfaces of the four sidewalls of the upper housing 101 form a smooth and closed annular inclined surface. When the inner surface of the sidewall needs to avoid the rotating shaft, at this time, the inner surfaces of the four sidewalls form an unclosed annular inclined surface. It should be noted that Figure 8 This is only a schematic diagram to illustrate the situation where the inner surface of the sidewall of the upper housing 101 is inclined.

[0137] In another specific embodiment, the inner surface of the sidewall of the upper housing 101 is neither vertically arranged nor inclined, but is arc-shaped, and the curvature of the arc is the same as the curvature of the outer surface of the sidewall. That is to say, in this solution, the inner surface and the outer surface of the sidewall of the upper housing have the same shape, and the bending directions of the arcs are also the same. Therefore, when the inner surface of the sidewall does not need to avoid the rotating shaft, the inner surfaces of the four sidewalls of the upper housing 101 form a smooth closed annular curved surface. When the inner surface of the sidewall needs to avoid the rotating shaft, at this time, the inner surfaces of the four sidewalls form an unclosed annular curved surface.

[0138] In the solution disclosed herein, in order to enable the user to distinguish the first side and the second side only by touch, grooves can be provided only on the second side where the opening / closing area is located, and no grooves are provided on the first side where the rotating shaft is located. When grooves are provided on both the first side and the second side, in order to enable the user to locate the opening / closing area by touch, different materials can be used for the outer surface at the opening / closing area and the outer surface on the rotating shaft side during production. Or the outer surfaces at the opening / closing area and on the rotating shaft side are made into different shapes.

[0139] For the earphone case provided in this disclosure, the groove 103 is no longer provided only in the middle area where the housing abuts on the second side like a traditional earphone case, but in all areas where the housing abuts on the second side. The area occupied on the earphone case is increased, enabling the user to open the earphone case by applying force at different positions, and the operation is more convenient.

[0140] In the solution disclosed herein, when the upper housing of the earphone case is a transparent housing and the outer surface and the inner surface of the upper housing form a curved surface, the curved surface will cause light to refract at different angles, resulting in the visual effects of magnification, reduction or distortion of the objects inside the earphone case. And the solution disclosed herein will utilize the fact that the curved surface causes light to refract at different angles to achieve special visual effects for the design of the earphone case.

[0141] Those skilled in the art can understand that when the thickness of the sidewall of the upper housing of the earphone case remains unchanged and is perpendicular to the top surface, although refraction occurs when light enters the upper housing from the air, the refraction angle is not large, that is to say, the deformation of the earphone is not large, and the user can still clearly see the shape and position of the earphone through the transparent upper housing.

[0142] When the earphone is placed in the installation groove, due to the inconsistent distances between the various parts of the earphone and the sidewall of the upper housing, special light and shadow effects will be formed through the curved surface of the sidewall of the upper housing. For example, when the user gazes in the direction of the rotating shaft along the opening / closing area of the upper housing, a part of the earphone area may disappear or be distorted due to refraction, forming special visual effects.

[0143] The outer surface of the side wall of the upper shell of the earphone case in this disclosure is arc-shaped, and the inner surface is a vertical structure perpendicular to the top surface. Therefore, the inner surface and the outer surface of the first side wall form a plano-convex lens. When designing this plano-convex lens, the relative positions of various parts of the earphone and the upper shell need to be considered, so that clear imaging effects are formed in some areas of the earphone near the lens focus, and blurred imaging effects are formed in areas far from the focus. In this way, the earphone can form clear and blurred visual changes, enhancing the visual hierarchy.

[0144] According to the characteristics of the above-mentioned plano-convex lens, the important parts of the earphone can be set close to the focus, and the unimportant parts can be set far from the focus. For example, the charging contacts of the earphone are usually set on the earphone body part. Therefore, the body part can be set close to the focus, so that the user can clearly see the shape and location of the body part through the upper shell.

[0145] In addition, since the outer surface of the upper shell is a curved surface, the side wall of the upper shell can form a more obvious lens effect and the light-gathering effect of the lens at a very low height, making this area appear brighter. Therefore, for areas that need to enhance the visual effect, such as the edges or specific angles, the curvature of the outer surface of the shell and the thickness change of the inner surface are designed to form a lens effect. Ensure that the design of these areas can gather light, making specific parts appear brighter and increasing the visual attraction.

[0146] In the solution provided by this disclosure, in order to make the upper shell have a specific visual effect, before manufacturing the upper shell, the influence of different curvatures and wall thicknesses on light is first simulated by computer simulation, the design is optimized, and the parameters such as the curvature and wall thickness of the upper shell required to achieve the desired visual effect are determined. Then, the upper shell is manufactured according to the determined parameters.

[0147] In some embodiments of this disclosure, an earphone adapted to the earphone case is also provided.

[0148] Such as Figure 12As shown in the bottom view of the earphone, the earphone in this solution is an open earphone 200, which includes a main body part, an ear hook 203 and a battery part 204 connected in sequence. Specifically, the main body part includes a sound generating part 201 and a connecting part 202. The housing of the sound generating part 201 is a cylinder, and a sound outlet hole for sound output is provided on the end surface of the cylinder facing the human ear. The connecting part 202 is a strip-shaped structure with a certain thickness. One end of it is connected to the sound generating part 201, and the other end is connected to one end of the ear hook 203. More specifically, the sound generating part 201 includes a lower surface facing the ear canal direction and an upper surface away from the ear canal direction. The connecting part 202 includes a lower surface facing the ear canal direction and an upper surface away from the ear canal direction. At least the end part of the connecting part 202 is connected to the peripheral wall on the upper surface of the sound generating part 201, and the lower surface of the sound generating part 201 is convexly arranged above the lower surface of the connecting part 202. That is, there is a height difference between the lower surface of the connecting part 202 and the lower surface of the sound generating part 201, so that a stepped part is formed between the lower surface of the connecting part and the lower surface of the sound generating part 201.

[0149] When the earphone is placed in the earphone box, the sound generating part, the connecting part, the ear hook and the battery part of the earphone are respectively placed in their corresponding sound generating part slots, connecting part slots, ear hook slots and battery part slots. Since the depths of the sound generating part slot, the connecting part slot, the ear hook slot and the battery part slot are not the same, when the earphone is placed in the installation slot, part of it is completely located in the installation slot, and the other part protrudes from the installation slot.

[0150] In the implementation scheme disclosed in this disclosure, at least the connecting part and the battery part of the earphone protrude from the connecting part slot and the battery part slot. Also, since the top surface of the connecting part away from the installation slot is a plane and the battery part is a cylindrical structure, when the earphone is placed in the earphone box and the upper shell and the lower shell of the earphone box are in a closed state, at this time, the inner surface of the upper shell abuts against the top surface of the connecting part of the earphone or is 0.2 - 0.5 mm away from it to limit the connecting part. The outer surface of the first limiting part on the upper shell is tangent to the outer surface of the battery part or is 0.2 - 0.5 mm away from it to limit the battery part. That is to say, when the earphone is placed in the earphone box, the inner surface of the upper shell of the earphone box and the first limiting part cooperate with the installation slot to limit the earphone in the accommodation cavity inside the earphone box, avoiding the earphone from shifting due to the shaking of the earphone box and affecting charging.

[0151] In the solution disclosed in this disclosure, a magnet corresponding to the first magnetic part is provided on the sound generating part of the earphone. The magnet on the sound generating part cooperates with the first magnetic part in the sound generating part slot to better limit the sound generating part in the sound generating part slot. When the first magnetic part is arranged at the bottom of the sound generating part slot, the magnet is arranged on the lower surface of the sound generating part. When the first magnetic part is arranged on the peripheral wall of the sound generating part slot, the magnet is arranged on the peripheral wall of the sound generating part.

[0152] Those skilled in the art can understand that when a first magnetic member is provided in the connector groove, a magnet corresponding to the first magnetic member is provided on the connector. When first magnetic members are provided in both the sound generating portion groove and the connector groove, magnets are correspondingly provided on both the sound generating portion and the connector of the earphone.

[0153] The above solution introduces the earphone and the state of the earphone in the earphone case. To better understand the solution of the present disclosure, the structure of the human ear and the positional relationship between each component of the earphone and the human ear when the earphone is worn on the human ear will be described in detail below.

[0154] Specifically, as Figure 9 shown in the schematic diagram of the human ear structure, the externally visible regions of the human ear 300 include the helix 301, the scaphoid fossa 302, the cymba conchae 303, the concha cavum 304, the antihelix 305, the earlobe 306, the antitragus 307, the incisura intertragica 308, the tragus 309, the crus helicis 310, and the triangular fossa 311. In some embodiments, one or more parts of the human ear can be used to support the earphone to achieve stable wearing of the earphone.

[0155] In some embodiments, since parts such as the concha cavum 304, the cymba conchae 305, and the triangular fossa 311 all have a certain depth and volume in three-dimensional space, these three regions can all be used to accommodate the sound generating portion, so as to meet the wearing requirements of the earphone.

[0156] As Figure 10 and Figure 11 shown in the schematic diagram of the earphone worn on the human ear model, in the solution of the present disclosure, the sound generating portion is located in the concha cavum.

[0157] In a specific embodiment, when the earphone is worn on the human ear through the ear hook 203, since there is a step portion at the connection between the sound generating portion and the connector, part of the sound generating portion can penetrate into the concha cavum, and the free end of the sound generating portion forms a first support region with the human ear. The ear hook forms a suspension point on the upper part of the human ear, and the battery portion forms a third support region with the rear part of the human ear. The earphone is fixed in the vertical direction through the suspension point, and clamps the human ear in the horizontal direction through the first support region and the third support region. The triangle formed by connecting the first support region, the suspension point, and the third support region can stably fix the earphone in the relative position on the human ear. In this solution, the free end of the sound generating portion refers to the end far from the connection with the connector. The first support region refers to the region where the lower surface of the sound generating portion abuts against the bottom wall of the concha cavum, and the region where the peripheral wall at the free end of the sound generating portion abuts against the peripheral wall of the concha cavum.

[0158] In the above solution, the three regions where the earphone contacts the human ear are all smoothly transitioned, and the curvature is similar to the curvature of the human ear itself, so that the foreign body sensation can be reduced in the wearing state, approaching a feeling of wearing without any discomfort.

[0159] In some embodiments, the contact area between the earphone and the human ear is small, usually point contact, line contact or small surface contact. Coupled with the contoured design of the earphone itself, the clamping force exerted on the ear enables a stable fit on the human ear while also reducing the area where the clamping force is applied to the ear, improving the user's wearing experience.

[0160] More specifically, the part of the sound generating portion 201 protruding from the connecting member 202 is located in the concha 304, and the connecting member 202 extends obliquely upward through the area between the tragus 309 and the crus of helix 310 of the human ear. There is a concave area between the tragus 309 and the crus of helix 310. The connecting member 202 can avoid the tragus, so that the lower surface of the sound generating portion is at least partially in contact with the bottom wall of the concha, and the two tend to be parallel. When in use, even if the user's head shakes, the sound generating portion 201 can be limited in the concha, so that the sound holes on the sound generating portion can be aligned with the ear canal. This solution can effectively prevent the sound generating portion from moving and leaking sound, thus providing a better auditory experience for the user.

[0161] As Figure 16 shown in the perspective view of the earphone, in the solution disclosed herein, when the earphone is in the worn state, the connecting member extends obliquely upward from the connection end with the sound generating portion to the connection end with the ear hook. Specifically, there is an angle a between the connecting member and the parallel line of the human body vertical axis, where the value range of a is between 45° and 60°. In this solution, the human body vertical axis refers to the line that passes through the center of the human body in the height direction of the human body and is perpendicular to the ground when a person stands on a horizontal ground. The parallel line of the human body vertical axis refers to the straight line passing through the center of the upper surface of the sound generating portion.

[0162] In the above solution, since there is an angle between the connecting member and the parallel line of the human body vertical axis, the connecting member 201 is arranged through the area between the tragus 309 and the crus of helix 310. This setting method can make the connecting member avoid part of the tragus and make the ear hook wear more firmly.

[0163] As Figures 12 - 14 shown, in the solution disclosed herein, the connecting member 202 is a receiving cavity surrounded by a transparent or translucent housing, and electronic components are arranged in the receiving cavity. The housing covers part of the peripheral wall of the sound generating portion 201.

[0164] In the above solution, the connecting member 202 is a receiving cavity surrounded by a transparent or translucent housing, and electronic components are arranged in the receiving cavity. The housing includes a first housing 2021 and a second housing 2022. The first housing 2021 includes an integrally formed first part 2021-1, a second part 2021-2, and a third part 2021-3. The first part 2021-1 is a semi-enclosed cylindrical structure that covers a partial peripheral wall and a partial area of the upper surface of the sound generating part 201. Specifically, the semi-enclosed structure has a notch at the end facing the ear hook 203, and a hollowed-out part in the middle area and the area extending from the middle area to the end of the ear hook 203. The second part 2021-2 is disposed above the hollowed-out part of the first part 2021-1 and protrudes from the top surface of the first part 2021-1. The top surface of the first part 2021-1 refers to the surface facing away from the ear canal. The third part 2021-3 is disposed between the sound generating part 201 and the ear hook 203. One end of the third part 2021-3 is connected to the notch of the first part 2021-1, and the other end is abutted or fixedly connected to the ear hook 203. The third part 2021-3 has three side walls in its circumferential direction, namely an upper side wall facing away from the human ear, a right side wall facing the ear hook 203, and a left side wall disposed opposite to the right side wall. The third part and the second housing enclose a sleeve structure.

[0165] In the above solution, the direction in which the connecting member is close to or away from the human ear is the thickness direction, the extending direction of the two ends of the connecting member is the length direction, and the connecting direction between the left and right side walls is the width direction. In this solution, the width of the connecting member 202 is smaller than the diameter of the upper surface of the sound generating part 201. That is to say, the width of the second part 2021-2 is smaller than the diameter of the upper surface of the sound generating part 201. The connecting member 202 in this solution has a smaller volume, so that the earphone 200 does not cover the human ear in a large area, avoiding sweating of the covered part and affecting the user experience.

[0166] In the solution disclosed herein, the sound generating part 201 includes two parts. One part is a protruding part protruding from the connecting member 202, and the other part is the part covered by the first part. The area of the end face of the part covered by the first part is smaller than the area of the end face of the protruding part. The circle formed by the end of the first part is the same size as the circle of the end face of the protruding part. That is to say, when the first part covers the upper part of the sound generating part 201, the overall formed by the housing of the protruding part of the sound generating part 201 and the first part is a cylinder. Of course, in other embodiments, the areas of the end faces of the two parts of the sound generating part may also be the same.

[0167] In the solution disclosed herein, in order to more conveniently send control instructions to the earphone, a pressure sensor is provided on the inner surface of the side wall of the third part 2021-3. During use, when the user presses the side wall where the pressure sensor is located, after the pressure sensor receives the signal, it sends the control instruction corresponding to the signal to the earphone 200. After receiving the control instruction, the earphone 200 executes the operation corresponding to the control instruction.

[0168] Those skilled in the art can understand that the pressure sensor can be provided on the inner surface of any one or more of the upper side wall, left side wall, and right side wall of the third part. For example, when setting one pressure sensor, the pressure sensor can be separately provided on the inner surface of any one of the right side wall, right side wall, or upper side wall. For example, when two pressure sensors need to be set, they are usually set on the inner surfaces of the right side wall and the upper side wall or the inner surfaces of the left side wall and the upper side wall, and are avoided to be installed on the two relatively arranged left side wall and right side wall, so as to prevent accidentally touching another sensor when sending an instruction to one sensor.

[0169] In the solution disclosed herein, the body part includes a sound generating part and a connecting part. When the earphone is placed in the earphone case, the connecting part is located above the sound generating part, and the connecting part is a square structure. Compared with the cylindrical structure of the battery part, this structure is easier to grasp. When the user grasps the earphone, it guides the user to position the hand at the connecting part, and then when taking the earphone out of the earphone case by grasping the side wall of the connecting part, a fixed taking method is formed.

[0170] In the solution provided by this disclosure, the sound generating part 201 and the ear hook 203 can be directly connected by the connecting part 202, or can be connected by a fixing part inside the connecting part 202.

[0171] In a specific implementation, the end of the ear hook 203 connected to the connecting part 202 has an arc-shaped groove extending in a direction away from the sound generating part 201, and the first housing has a connecting part extending towards the end of the ear hook 203. Specifically, the upper side wall of the third part extends vertically towards the second housing, and the extending end extends parallel to the second housing towards the ear hook 203 to form a connecting part. The second housing has a connecting part extending towards the end of the ear hook 203. The two connecting parts are inserted into the arc-shaped groove to connect the connecting part 202 and the ear hook 203.

[0172] Based on the above solution, those skilled in the art can understand that the second housing is fixedly connected to the third part, and then the connecting part and the ear hook can still be connected only by connecting the ear hook through the second housing or the third part.

[0173] In the above solution, in order to tighten the connection between the sound-emitting part and the ear hook, a fastener is provided at the connection between the two. The fastener passes through the fastening hole 203-4 on the ear hook, the connection part of the third part and the connection part of the second shell in sequence to fix the three parts together. Alternatively, the fastener passes through the fastening hole 203-4 on the ear hook and the connection part of the third part in sequence to fix the two together. Alternatively, the fastener passes through the fastening hole 203-4 on the ear hook and the connection part of the second shell in sequence to fix the two together. This solution can reduce the amount of glue used and avoid affecting the appearance of the connector 202. In particular, when the connector is a transparent / translucent part, glue overflow is reduced inside or at the joint, which can significantly optimize the appearance effect.

[0174] To provide a better wearing experience, when the sound-emitting portion 201 is inserted into the cavum concha, the outer periphery of the sound-emitting portion 201 minimizes contact with the antihelix, antitragus, and tragus. Therefore, in this embodiment, the diameter of the lower surface of the sound-emitting portion 201 is set to be smaller than the diameter of a circle tangent to the antihelix, antitragus, and tragus. In some specific embodiments, the diameter of the lower surface of the sound-emitting portion 201 ranges from 14 to 16.5 mm, thereby matching the average diameter of the cavum concha of the human ear.

[0175] The above embodiment introduces the sound-emitting part 201 and the connecting part 202 , and the ear hook 203 and the battery part 204 are described in detail below.

[0176] In the disclosed embodiment, the ear hook 203 secures the earphone 200 to the human ear. Therefore, the ear hook 203 is a curved structure that conforms to the outer contour of the human ear. Specifically, the ear hook 203 extends obliquely from the end connected to the third section toward the right side wall of the third section, then extends toward the end of the sound-emitting portion 201 away from the connector 202. Its extended end is located at the end of the sound-emitting portion 201 and is connected to the battery portion 204. In this embodiment, the ear hook 203 may include three consecutive curved sections: a first curved section, a second curved section, and a third curved section. Specifically, the first curved section begins at the end connected to the connector 202 and extends toward the right side wall of the third section. The second curved section continues the first curved section and extends generally along the right side wall of the third section. The third curved section continues the second curved section and extends obliquely to the end of the sound-emitting portion 201 away from the connector 202. For example, the first curved section has the smallest radius of curvature, the second curved section has the second smallest radius of curvature, and the third curved section has the largest radius of curvature. This gradual curvature design enables the ear hook 203 to better fit the shape of the human ear contour.

[0177] like Figure 13As shown in the front view of the earphone, since the function of the earhook 203 is to fix the earphone 200 on the human ear, and the human ear usually extends obliquely outward relative to the side of the head, forming an angle with the head. In order to better adapt to the human ear, the earhook 203 in this solution first extends obliquely downward below the lower surface of the sound generating part 201, and then extends obliquely upward toward the upper surface of the sound generating part 201, and the end of its extension is slightly higher than the upper end surface of the first part or is flush with the upper end wall of the first part. Since there is an angle of 25°-30° between the human ear and the head, in order to better fit the human ear, there is an angle b between the middle area of the earhook and both ends of the earhook in this solution. In a specific embodiment, b is 30°.

[0178] The diameter of the earhook 203 in the above solution changes from the connection with the sound generating part 201 to the connection with the battery part 204. The earhook 203 is generally a cylindrical structure as a whole, and it successively includes a first diameter-changing section 203-1, a diameter section 203-2, and a second diameter-changing section 203-3. The first diameter-changing section 203-1 refers to the area from the connection of the earhook with the sound generating part to the top of the earhook, and the diameter gradually becomes smaller in this area. The second diameter-changing section 203-3 is the end of the earhook 203 connected to the battery part 204. The second diameter-changing section 203-3 is in a trumpet shape, and the diameter of the earhook at this position rapidly changes from small to large, and the maximum diameter is connected to the battery part. The diameter section 203-2 is located between the first diameter-changing section and the second diameter-changing section.

[0179] When the earphone 200 is in a worn state, the first diameter-changing section 203-1 is located at the front side of the human ear to the upper part of the auricle, the diameter section 203-2 is located in the middle area at the back of the human ear, and the second diameter-changing section 203-3 is located in the middle and lower area at the back of the human ear. In this solution, the starting position of the first diameter-changing section is the connection with the connecting member 202, and the end position is the top of the earhook 204. This top is the area at the top of the human ear and the areas slightly forward and backward of the top. That is to say, this top refers to a certain area extending forward and backward at the suspension point of the earhook and the upper part of the human ear. In this solution, as the inner diameter of the first diameter-changing section gradually becomes smaller, it can effectively avoid the temple of the glasses worn by the user or other ornaments, thereby improving the user experience.

[0180] In a specific embodiment, the first diameter-changing section of the ear hook is not cylindrical but has an irregular shape. Specifically, the thickness of the first diameter-changing section gradually decreases from the starting position to the end position, and the width also gradually decreases. In this solution, the thickness direction refers to the direction in which the ear hook approaches or moves away from the human ear, the length direction refers to the extending direction of the first diameter-changing section, and the width direction refers to the direction perpendicular to the length direction and the thickness direction. Since the thickness of the first diameter-changing section gradually decreases in the thickness direction, the first diameter-changing section is thinnest at the area above the human ear, thus being able to better avoid the temple of the glasses or accessories such as hairpins worn by the user and improve the user experience.

[0181] As Figure 16 As shown in the perspective view of the earphone, in the solution provided by this disclosure, the battery part 204 is cylindrical. One end of it is connected to the ear hook 203, and the other end extends away from the ear hook 203, and the extending end thereof exceeds the sound-generating part 201. In this solution, the connection part between the ear hook 203 and the battery part 204 is located on the free end side of the sound-generating part 201. When the ear hook is in the non-wearing state, the distance between the connection part of the ear hook and the battery part 204 and the free end of the sound-generating part is h. In this solution, h is 3 - 5 mm. In a specific embodiment, h is 3.6 mm.

[0182] In the solution of this disclosure, in the wearing state, the area of the ear hook located before and after the suspension point above the human ear is the top end of the ear hook; on the surface of the sound-generating part 201 close to the ear canal direction, a front sound outlet hole 2011 is provided, and on the peripheral wall of the sound-generating part 201, a rear sound outlet hole 2012 is provided. Both the front sound outlet hole 2011 and the rear sound outlet hole 2012 are arc-shaped and are both provided on the surface of the sound-generating part 201 away from the top end of the ear hook 203.

[0183] In the above solution, on the surface of the sound-generating part 201 of the earphone 200 away from the top end of the ear hook 203, there are two sound outlet holes, namely the front sound outlet hole 2011 and the rear sound outlet hole 2012, both of which are smooth circular arcs. Specifically, the front sound outlet hole 2011 is provided on the lower surface of the sound-generating part 201. The rear sound outlet hole 2012 is provided at the peripheral wall of the sound-generating part 201 covered by the first part. More specifically, the rear sound outlet hole 2012 extends at the peripheral wall of the sound-generating part 201 on the side away from the ear hook 203, and the front sound outlet hole 2011 extends at the lower surface of the sound-generating part 201 close to the rear sound outlet hole 2012, and the bending direction of the front sound outlet hole 2011 is opposite to the bending direction of the ear hook 203.

[0184] In the solution disclosed herein, when the earphone 200 is in a worn state, the bending direction of the arc of the front sound hole 2011 is set towards the rear of the human ear. This solution is less likely to have impurities and the like accumulate in the area where the sound hole is located compared to the earphone 200 with the front sound hole 2011 set towards the upper part of the human ear, and is cleaner and tidier.

[0185] In the solution disclosed herein, at the end position where the earhook is connected to the connecting member, there is a first microphone 2024, and the first microphone 2024 is arranged away from the top end of the earhook; on the side wall of the housing towards the top end of the earhook, there is a second microphone 2025.

[0186] In a specific implementation, two microphones are further provided on the earphone 200, namely a first microphone 2024 and a second microphone 2025. Specifically, the first microphone 2024 is arranged on the second part of the connecting member 202, and the second microphone 2025 is arranged on the earhook 203. More specifically, the first microphone 2024 is arranged at the end position where the earhook 203 is connected to the left side wall of the second part, and the first microphone 2024 is arranged away from the top end of the earhook. The second microphone 2025 is arranged at the side wall of the second part of the housing towards the top end direction of the earhook 203, and the side wall of the housing towards the top end direction of the earhook forms a wind shelter area with the human ear, that is to say, the second microphone 2025 is located in the wind shelter area.

[0187] In the solution disclosed herein, the second microphone 2025 is arranged towards the top end direction of the earhook. When the earphone 200 is in a worn state, the second microphone 2025 is in the wind shelter area of the earphone, so as to avoid direct wind blowing to the second microphone 2025 and causing interference to it, thereby affecting the call quality.

[0188] In the solution disclosed herein, when the earphone is placed in the earphone box, the thickness of the connecting member of the earphone protruding from the installation groove accounts for at least one - half of its total thickness.

[0189] In the above - mentioned solution, the thickness of the earphone body part is 12 mm, the thickness of the sound - generating part protruding from the connecting member is 2 - 4 mm, and this part is completely located in the sound - generating part groove. The thickness of the third part of the connecting member is 7 - 11 mm. When the earphone is placed in the earphone box, the thickness of the connecting member protruding from the connecting member groove is 6 - 8 mm.

[0190] In a specific implementation, the thickness of the earphone body part is 12 mm, the thickness of the sound - generating part protruding from the connecting member is 3 mm, and this part is completely located in the sound - generating part groove. The thickness of the third part of the connecting member is 9 mm. When the earphone is placed in the earphone box, the thickness of the connecting member protruding from the connecting member groove is 7 mm.

[0191] In addition, in this solution, the thickness of the battery part is almost the same as that of the main body part, and the ratio of the thickness by which the battery part protrudes from the battery part groove is the same as the ratio of the thickness by which the main body part protrudes from the main body part groove.

[0192] In this solution, after the earphone is placed in the installation groove, the thickness by which it protrudes from the installation groove is relatively large, thereby providing sufficient space for the user to pick it up, facilitating the user to perform the pick-up and put-down operations on the earphone.

[0193] For the earphone 200 provided in this disclosure, the stepped portion formed between the sound generating portion 201 and the connecting member 202 can avoid part of the tragus, so that the sound generating portion 201 can be better located in the concha. During the wearing process of the earphone 200, the sound generating portion 201 will not easily detach from the concha due to the shaking of the head, which affects the user's reception of the sound emitted by the earphone 200. This solution can improve the user experience.

[0194] Although multiple embodiments of this disclosure have been shown and described herein, it will be apparent to those skilled in the art that such embodiments are provided by way of example only. Those skilled in the art can think of many changes, alterations, and alternative ways without departing from the spirit and scope of this disclosure. It should be understood that various alternative embodiments of the disclosure described herein can be adopted in the practice of this disclosure. The appended claims are intended to define the scope of protection of this disclosure and thus cover equivalents or alternatives within the scope of these claims.
