Description

Technical Field

[0001] This disclosure generally relates to the technical field of electronic devices. More specifically, this disclosure relates to a pair of earphones, and further to a earphone case. Background Art

[0002] With the development of society, audio devices are increasingly favored by consumers. Audio devices can be used in offices, daily life, or daily travel, so that users can connect them to electronic devices to achieve functions such as remote work, watching videos, playing games, listening to music, 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 office places, users usually use earphones in combination with the audio device. With the progress of technology, Bluetooth earphones are deeply loved by people due to their advantages such as no wire entanglement. Bluetooth earphones usually include in-ear Bluetooth earphones and open Bluetooth earphones. Different types of earphones have different advantages and disadvantages. For example, in-ear Bluetooth earphones have good noise reduction functions, but since the sound outlet holes of in-ear Bluetooth earphones need to be inserted into the ear canals, they will cause a sense of compression on the ear canals of the wearer, making the human ear feel uncomfortable. In order to avoid discomfort in the ears when wearing earphones, users usually choose open Bluetooth earphones. The sound outlet holes of open Bluetooth earphones do not need to be inserted into the ear canals, but are located outside the ear canals and point to the ear canals. Therefore, open Bluetooth earphones are more comfortable to wear.

[0004] When open Bluetooth earphones are worn, they are fixed to the human ear by the sound generating part and the ear hook. However, when fixing the earphones, if they are clamped too tightly, the user's comfort is poor, and if they are clamped too loosely, the earphones are likely to fall off. Therefore, how to firmly fix the earphones on the human ear while ensuring the comfort of the human ear is still a problem to be solved. In view of this, there is an urgent need to provide an earphone and an earphone case. The earphone provided by this solution can fix the sound generating part more firmly on the human ear without deviation, and can reduce the discomfort to the human ear when fixed on the human ear. When the user does relatively strenuous exercise, the sound outlet hole can also face the direction of the ear canal, improving the user's experience. Summary of the Utility Model

[0009] In some embodiments, a groove is provided at the end where the ear hook is connected to the connector, and the shell of the connector includes a first shell and a second shell, and the first shell and / or the second shell are inserted into the groove of the ear hook.

[0010] In some embodiments, when worn, the ear hook is located at the hanging point on the upper part of the human ear and the area near the hanging point is the top of the ear hook; a front sound hole is provided on the surface of the sound-emitting part close to the ear canal, and a rear sound hole is provided on the peripheral wall of the sound-emitting part. The front sound hole and the rear sound hole are both arc-shaped and are both arranged on the surface of the sound-emitting part away from the top of the ear hook.

[0011] In some embodiments, a first microphone is provided at the end where the ear hook is connected to the connector, and the first microphone is arranged away from the top of the ear hook; a second microphone is provided on the side wall of the shell facing the top of the ear hook, and the side wall facing the top of the ear hook forms a wind shelter with the human ear.

[0012] In some embodiments, when the earphone is worn, the direction in which the earphone approaches or moves away from the human ear is the thickness direction; and the thickness of the ear hook gradually decreases from the connection with the sound-emitting part to the top.

[0013] In some embodiments, the shell of the sound-emitting part is a cylinder, and the diameter of the end face of the cylinder is smaller than the diameter of a circle simultaneously tangent to the antihelix, the antitragus and the tragus.

[0014] In some embodiments, the diameter of the end surface of the sound-emitting portion ranges from 14 to 16.5 mm.

[0042] The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0043] The present disclosure provides a headset. The sound - generating part 201 and the connecting part 202 of the headset 200 are formed with a stepped part in the direction towards the ear canal. Thus, during the wearing process of the headset 200, the stepped part can avoid the tragus and the crus of helix, and the part where the sound - generating part 201 protrudes beyond the connecting part 202 can penetrate into the concha area, making the headset 200 wear more firmly and being able to prevent the headset from leaking sound.

[0044] As Figure 4 As shown in the bottom view of the headset, the headset in this solution is an open - type headset 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 - emitting hole for emitting sound is provided on the end face of the cylinder facing the human ear. The connecting part 202 is a strip - shaped structure with a certain thickness, one end of which 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, and the connecting part 202 includes a lower surface facing the ear canal direction and an upper surface away from the ear canal direction. The end of the connecting part 202 is connected to at least the peripheral wall of 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 as to form a stepped part between the lower surface of the connecting part and the lower surface of the sound - generating part 201.

[0045] To better understand the solutions of this 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 introduced in detail below.

[0046] Specifically, as Figure 1 shown in the schematic diagram of the human ear structure, the externally visible area of the human ear 300 includes 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 of helix 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 earphone wearing.

[0047] 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 part, so as to meet the earphone wearing requirements.

[0048] As Figure 2 and Figure 3 shown in the schematic diagram of the earphone worn on the human ear model, in the solutions of this disclosure, the sound generating part is located in the concha cavum.

[0049] In a specific embodiment, when the earphone is worn on the human ear through the ear hook 203, since there is a step at the connection between the sound generating part and the connecting part, part of the sound generating part can penetrate into the concha cavum, and the free end of the sound generating part forms a first support area with the human ear. The ear hook forms a suspension point on the upper part of the human ear, and the battery part forms a third support area with the back 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 area and the third support area. The triangle formed by connecting the first support area, the suspension point, and the third support area can stably fix the earphone in the relative position on the human ear. In this solution, the free end of the sound generating part refers to the end far from the connection with the connecting part. The first support area refers to the area where the lower surface of the sound generating part abuts against the bottom wall of the concha cavum, and the area where the peripheral wall at the free end of the sound generating part abuts against the peripheral wall of the concha cavum.

[0050] In the above solutions, the three areas where the earphone contacts the human ear are all smoothly transitioned, and the curvature is similar to that of the human ear itself, so that the foreign body sensation can be reduced during the wearing state, approaching a feeling of wearing without any discomfort.

[0051] 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 and the clamping force exerted on the ear, on the basis of stable wearing on the human ear, the area where the clamping force is exerted on the ear can also be reduced, improving the wearing experience of the user.

[0052] More specifically, the part of the sound generating part 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 part is at least partially in contact with the bottom wall of the concha, and the two tend to be parallel.

[0053] During use, even if the user's head shakes, the sound generating part 201 can be limited in the concha, so that the sound holes on the sound generating part can be aligned with the ear canal. This solution can effectively prevent the sound generating part from moving and leaking sound, thus providing a better auditory experience for the user.

[0054] As Figure 8 shown, in the solution disclosed in this disclosure, when the earphone is in the worn state, the connecting member extends obliquely upward from the connecting end with the sound generating part to the connecting end with the ear hook. Specifically, there is an included angle a between the connecting member and the parallel line of the human body vertical axis, and 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 the 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 part.

[0055] In the above solution, since there is an included 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.

[0056] As Figures 5 - 7 shown in the schematic diagram of the earphone in other directions, in the solution provided by this disclosure, the connecting member 202 is an accommodation cavity surrounded by a transparent or semi-transparent shell, and electronic components are arranged in the accommodation cavity, and the shell covers part of the peripheral wall of the sound generating part 201.

[0057] 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 cylindrical semi-surrounding structure that covers a partial peripheral wall and a partial area of the upper surface of the sound generating part 201. Specifically, the semi-surrounding 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 towards the end of the ear hook 203. The second part 2021-2 is arranged above the hollowed-out part of the first part 2021-1 and protrudes from the top surface of the first part 2021-1, where the top surface of the first part 2021-1 refers to the surface away from the ear canal. The third part 2021-3 is arranged 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 arranged opposite to the right side wall. The third part and the second housing enclose a sleeve structure.

[0058] 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 a large area of the human ear, avoiding sweating in the covered part and affecting the user experience.

[0059] In the solution disclosed herein, the sound generating part 201 includes two parts. One part is a protruding part that protrudes from the connecting member 202, and the other part is the part covered by the first part. The area of the end surface of the part covered by the first part is smaller than the area of the end surface of the protruding part, and the circle formed by the end of the first part is the same size as the circle of the end surface of the protruding part. That is to say, when the first part is arranged above 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 surfaces of the two parts of the sound generating part may also be the same.

[0060] 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, 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.

[0061] 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, the left side wall, and the right side wall of the third part. For example, when one pressure sensor is provided, the pressure sensor can be separately provided on the inner surface of any one of the right side wall, the right side wall, or the upper side wall. For example, when two pressure sensors need to be provided, they are usually provided 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.

[0062] In the solution provided by this disclosure, the sound generating part 201 and the ear hook 203 can be directly connected by the connecting member 202, or can be connected by the fixing member inside the connecting member 202.

[0063] In a specific implementation, the end of the ear hook 203 connected to the connecting member 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 member 202 with the ear hook 203.

[0064] 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 member can still be connected to the ear hook only through the second housing or the third part and the ear hook.

[0065] 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.

[0066] In another specific embodiment, a fixing member is contained within the sleeve formed by the third portion and the second housing. One end of the fixing member is connected to the sound-emitting portion 201, and the other end is connected to the ear hook 203. In this embodiment, the fixing member serves as a connection, while the third portion and the second housing are merely provided around the outer periphery of the fixing member to protect it and provide aesthetics.

[0067] 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.

[0068] 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.

[0069] In the disclosed embodiment, the ear hook 203 secures the earphone 200 to the ear. Therefore, the ear hook 203 is curved to conform to the outer contour of the ear. Specifically, the ear hook 203 extends from the end connected to the third portion, first obliquely toward the right side wall of the third portion, then toward the end of the sound-emitting portion 201 away from the connector 202. The extended end is located at the end of the sound-emitting portion 201 and is connected to the battery portion 204.

[0070] In this solution, the earhook 203 may include three consecutive curved segments: a first curved segment, a second curved segment, and a third curved segment. Specifically, the first curved segment starts from the end connected to the connecting member 202 and extends towards the right side wall of the third part; the second curved segment follows the first curved segment and extends substantially along the right side wall of the third part; the third curved segment follows the second curved segment and extends obliquely to near the end of the sound generating part 201 away from the connecting member 202. As an example, the first curved segment has the smallest radius of curvature, the second curved segment has the second smallest, and the third curved segment has the largest radius of curvature. This gradually changing curvature design enables the earhook 203 to better conform to the shape of the outer contour of the human ear.

[0071] As Figure 4 As shown in the bottom 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 fit 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 towards 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 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 the two ends of the earhook in this solution. In a specific embodiment, b is 30°.

[0072] The diameter of the earhook 20⑶ 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 sequentially includes a first diameter-changing segment 203-1, a diameter segment 203-2, and a second diameter-changing segment 203-3. The first diameter-changing segment 203-1 refers to the area from the connection of the earhook with the sound generating part to the top of the earhook, where the diameter gradually becomes smaller. The second diameter-changing segment 203-3 is the end of the earhook 203 connected to the battery part 204. The second diameter-changing segment 203-3 is in a flared 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 segment 203-2 is located between the first diameter-changing segment and the second diameter-changing segment.

[0073] When the earphone 200 is in a worn state, the first diameter-changing section 203-1 is located in the area from 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 rear of the human ear, and the second diameter-changing section 203-3 is located in the lower middle area at the rear of the human ear. In this solution, the starting position of the first diameter-changing section is the connection with the connecting piece 202, and the end position is the top end of the earhook 204, and this top end is at the top of the human ear and the areas slightly in front of and behind 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.

[0074] In a specific implementation, the first diameter-changing section of the earhook 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 earhook 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. In this solution, since the first diameter-changing section gradually decreases in the thickness direction, the area of the first diameter-changing section located at the upper part of the human ear is the thinnest, so that it can better avoid the temple of the glasses worn by the user or ornaments such as hairpins, improving the user experience.

[0075] In the solution provided by this disclosure, the battery part 204 is cylindrical, one end of which is connected to the earhook 203, and the other end extends away from the earhook 203, and the extending end thereof exceeds the sound-generating part 201. In this solution, the connection between the earhook 203 and the battery part 204 is located on the free end side of the sound-generating part 201, and when the earhook is in a non-worn state, the distance between the connection between the earhook and the battery part 204 and the free end of the sound-generating part is h, where h is 3-5 mm in this solution. In a specific implementation, h is 3.6 mm.

[0076] In the solution provided by this disclosure, in the worn state, the area of the earhook at the suspension point and near the suspension point at the upper part of the human ear is the top end of the earhook; on the surface of the sound-generating part 201 close to the ear canal direction, a front sound outlet hole 2011 is opened, and on the peripheral wall of the sound-generating part 201, a rear sound outlet hole 2012 is opened. Both the front sound outlet hole 2011 and the rear sound outlet hole 2012 are arc-shaped and are both arranged on the surface of the sound-generating part 201 away from the top end of the earhook 203.

[0077] In the above solution, the sound-emitting part 201 of the earphone 200 has two sound outlets on the surface far from the top of the earhook 203, namely a front sound outlet 2011 and a rear sound outlet 2012, both of which are smooth circular arcs. Specifically, the front sound outlet 2011 is provided on the lower surface of the sound-emitting part 201. The rear sound outlet 2012 is provided at the peripheral wall of the sound-emitting part 201 covered by the first part. More specifically, the rear sound outlet 2012 extends at the peripheral wall of the sound-emitting part 201 on the side far from the top of the earhook 203, and the front sound outlet 2011 extends at the lower surface of the sound-emitting part 201 close to the rear sound outlet 2012, and the bending direction of the front sound outlet 2011 is opposite to the bending direction of the earhook 203.

[0078] In the solution disclosed herein, when the earphone 200 is in a worn state, the bending direction of the arc of the front sound outlet 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 outlet is located compared to the earphone 200 with the front sound outlet 2011 set towards the upper part of the human ear, and is cleaner and tidier.

[0079] In the solution provided by this disclosure, 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 provided far from the top of the earhook; on the side wall of the housing towards the top of the earhook, there is a second microphone 2025.

[0080] 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 provided on the second part of the connecting member 202, and the second microphone 2025 is provided on the earhook 203. More specifically, the first microphone 2024 is provided 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 provided far from the top of the earhook. The second microphone 2025 is provided at the side wall of the second part of the housing towards the top of the earhook 203, and the side wall of the housing towards the top 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.

[0081] In the solution disclosed herein, the second microphone 2025 is set towards the top 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 the wind directly blowing to the second microphone 2025 and interfering with it, thereby affecting the call quality.

[0082] The earphone 200 provided by the present disclosure has a stepped portion formed between the sound generating portion 201 and the connecting member 202, which 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.

[0083] The present disclosure also provides a earphone case for use with the earphone.

[0084] As Figure 9 As shown in the perspective view of the earphone case, the earphone case 100 provided by the present disclosure includes an upper case 101 and a lower case 102, and both the upper case 101 and the lower case 102 are open structures, and they jointly enclose a receiving cavity for receiving the earphone. Specifically, the earphone case 100 of the present disclosure has a certain extended length, and the upper case 101 and the lower case 102 are rotatably connected by a rotating shaft provided on the first side in the extended length direction, and the second side opposite to the first side is the opening and closing area. When in use, the upper case 101 in the opening and closing area rotates along the rotating shaft to open or close the earphone case 100.

[0085] In the solution of the present disclosure, when the earphone is placed in the earphone case, the thickness of the earphone protruding from the mounting groove accounts for at least one half of its total thickness.

[0086] In the above 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 the protruding 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 case, the thickness of the connecting member protruding from the connecting member groove is 6 - 8 mm.

[0087] In a specific embodiment, 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 the protruding 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 case, the thickness of the connecting member protruding from the connecting member groove is 7 mm.

[0088] In addition, in this solution, the thickness of the battery part is almost the same as that of the body part, and the ratio of the thickness of the battery part protruding from the battery part groove is the same as the ratio of the thickness of the body part protruding from the body part groove.

[0089] In this solution, after the earphone is placed in the mounting groove, the thickness of the earphone protruding from the mounting groove is relatively large, thereby providing sufficient space for the user to pick up, which is convenient for the user to perform the pick-up and put-down operations on the earphone.

[0090] In the solution of the present disclosure, taking the side where the opening and closing area is located as the main viewing area, the side where the rotating shaft is located as the rear viewing area, and the two end parts of the earphone case on the left and right are respectively the left viewing area and the right viewing area.

[0091] The earphone case in the above solution has a profiling cavity for accommodating the earphones. The profiling cavity is formed by the mounting groove on the lower housing and the upper housing. For the convenience of understanding the solution of the present disclosure, the mounting groove in the present solution will be introduced below.

[0092] As Figure 11 As shown in the schematic diagram of the inner surface of the upper housing of the earphone case, the mounting groove includes a body part groove for accommodating the earphone body, an ear hook groove 1023 for accommodating the ear hook, and a battery part groove 1024 for accommodating the battery part, which are connected in sequence. The body part groove also includes a sounding part groove 1021 and a connecting part groove 1022 that are connected in sequence, and the connecting part groove 1022 is connected to one end of the ear hook groove.

[0093] The mounting groove in the present disclosure includes a first mounting groove and a second mounting groove that are symmetrically arranged along the first axis. The first axis is the perpendicular bisector of the two ends of the earphone case 100 in its length direction. Next, taking the left first mounting groove as an example for introduction, the body part groove is arranged in the middle area and extends obliquely towards the second side position in the area close to the left end. The extension end of the body part groove 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 on the first side close to the first axis. The extension end of the ear hook groove 1023 is connected to the battery part groove 1024, and the battery part groove 1024 continues to extend towards the position on the first side close to the first axis. Similarly, the second mounting groove is symmetrically arranged with the first mounting groove along the first axis. The difference between the second mounting groove and the first mounting groove is that the 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 body part groove and the battery part groove 1024 are linear, and the extension trajectory of the ear hook groove 1023 is arc-shaped.

[0094] In the solution of the present disclosure, the earphone case has two independent cavities that are symmetrically arranged along the first symmetry axis, 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 groove in the present 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 left first mounting groove corresponds to the user's left hand side, the right second mounting groove 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.

[0095] 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 sound emitting part towards the human ear. When it reaches the position of the human ear, after hanging the ear hook above the human ear, fix the sound emitting 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 tragus and the crus of helix of the human ear to complete the wearing. Therefore, in the solution disclosed in this disclosure, on the basis that the battery part slot is arranged close to the first axis and the main body part slot is arranged away from the first axis relative to the battery part slot, the ear hook is arranged close to the rotating shaft side and the main body part is arranged 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, and this solution can be completed with one hand. In addition, in this solution, the direction in which the sound emitting part of the earphone faces is always the same as the direction in 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.

[0096] In the solution disclosed in this disclosure, the main body part includes a sound emitting part and a connecting part. When the earphone is placed in the earphone case, the connecting part is located above the sound emitting part, and the connecting part is a square structure, which is easier to grasp compared with the cylindrical structure of the battery part. When the user grasps the earphone, it guides the user to position the hand at the connecting part, and then picks up the earphone from the earphone case by grasping the side wall of the connecting part, thus forming a fixed picking-up method.

[0097] In the solution disclosed in this disclosure, based on the setting form of the installation slots, when the user uses it, the first installation slot on the left corresponds to the left hand side of the user, and the second installation slot on the right corresponds to the right hand side of the user. When the user wears the earphone, if wearing the left earphone, only need to pick up the main body part with the left hand and then place the sound emitting part in the concha, and hang the ear hook above the human ear to complete the wearing. Similarly, when wearing the right earphone, just operate with the right hand.

[0098] In addition, the earphone in this disclosure is not a planar structure in its thickness direction. In order to better limit the earphone, the depths of each part of the installation slot are not the same. Specifically, the depth of the middle area of the ear hook slot is greater than the depth of the sound emitting part slot 1021, the depth of the sound emitting part slot 1021 is greater than the depth of the connecting part slot 1022. The depth of the area of the ear hook slot close to the connecting part slot 1022 is greater than the depth of the connecting part slot 1022, and the depth of the area of the ear hook slot close to the battery part slot is less than the depth of the battery part slot. In this solution, the thickness direction of the earphone body refers to the direction of approaching or departing from the human ear when the earphone is in the wearing state.

[0099] In order to facilitate the understanding of the scheme disclosed in this invention, the reasons for the different depths of the mounting grooves are described in detail below. The earphones disclosed in this invention are open-type earphones. When in use, the user fixes the earphones 200 on the human ears through ear hooks, and the human ears are usually tilted and extended outward relative to the side of the head, forming an angle between the ear and the head. In order to better fit the human ear, the ear hooks of the earphones in this solution are tilted relative to the earphone body. That is to say, the ear hook has an inclination relative to the thickness direction of the earphone body, and the inclination is similar to the angle formed between the human ear and the head. In order to better place the ear hook in the ear hook groove, the depth of the middle area of the ear hook groove is set to be the deepest.

[0100] Since the earphone body includes a sound-emitting part and a connecting part, the lower surface of the sound-emitting part near the ear canal is protruding from the lower surface of the connecting part near the ear canal, so the depth of the sound-emitting part groove 1021 accommodating the sound-emitting part is greater than the depth of the connecting part groove 1022 accommodating the connecting part.

[0101] Furthermore, since one end of the ear hook is connected to the connector and the other end is connected to the battery unit, when the earphones are being worn, the end of the ear hook connected to the connector is located in the area of the human ear close to the face, so the ear hook at this position is inclined to extend toward the lower surface of the earphone body, and the middle area is further inclined to extend toward the upper surface of the earphone body, and its extended end is connected to the battery unit, and the upper end of the battery unit away from the ear canal is slightly lower than the upper end of the connector or is almost flush with the upper end of the connector, so the depth of the battery unit groove is slightly less than the depth of the sound-producing unit groove 1021 or is the same as the depth of the sound-producing unit groove 1021, the depth of the ear hook groove near the connector groove 1022 is greater than the depth of the connector groove 1022, and the depth of the ear hook groove near the battery groove is less than the depth of the battery unit groove.

[0102] In the solution disclosed herein, a battery is provided in the earphone box, and the battery is specifically provided in the middle area inside the lower shell of the earphone box. Figure 12 As shown in the schematic diagram of the lower shell of the earphone box, the middle area of the ear hook slot 1023 in this solution has the largest depth, and the middle area of the ear hook slot 1023 is located at the two ends of the earphone box. Through such a depth design, the depth of the mounting groove in the middle area of the earphone box is shallower, so there is enough space below this area to accommodate the battery. Therefore, the battery in the lower shell of the earphone box can be made thicker, and there is no need to cut the battery into two pieces and install them under the first mounting groove and the second mounting groove respectively. It only needs to be made into one piece and installed between the two ear hook slots. Through this design, when making the earphone box, improving the demoulding efficiency can reduce the process steps and improve production efficiency.

[0103] like Figures 10 - 11As shown in the schematic diagram of the inner surface of the upper shell of the earphone case and the schematic diagram of the inner surface of the lower shell, in one embodiment, the limiting portions for limiting the earphones on the upper shell 101 include a first limiting portion 1011 and a second limiting portion 1012. The first limiting portion 1011 extends from the inner surface of the upper shell 101 towards the lower shell 102, that is to say, the first limiting portion 1011 is a protruding structure provided on the inner surface of the upper shell 101. This protruding structure is provided on the first axis and is symmetrically arranged along the first axis. Since the battery portion slots 1024 in the first installation slot and the second installation slot are opposite and inclined in this disclosure, two battery portion slots 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 a closed state, the projected part of the first limiting portion 1011 on the lower shell 102 falls into the V-shaped area 1026 and part of it falls into the battery portion slot 1024. The projection of the first limiting portion 1011 in the battery portion slot 1024 is the first part, and the first part and the first limiting portion 1011 provided above it together constitute the first limiting area. Also, since the projection of the first limiting portion 1011 falls into the battery portion slot 1024 of the first installation slot and the battery portion slot 1024 of the second installation slot at the same time, the first limiting portion 1011 and the first parts of the two battery portion slots 1024 together constitute two first limiting areas.

[0104] In the above solution, the second limiting portion 1012 is also provided on the inner surface of the upper shell 101 facing the accommodating cavity, and the second limiting portion is a plane or a curved surface. The second limiting portion 1012 is arranged opposite to the second part of the installation slot, and the second limiting portion 1 is 012 and the second part constitute the second limiting area. In one embodiment of this solution, the second part of the installation slot refers to the area where the orthographic projection of the body portion slot of the earphone on the inner surface of the upper shell is located, and the body portion slot and the second limiting portion 1012 constitute the second limiting area. When the earphone is installed in the installation slot and the upper shell and the lower shell are in a closed state, the top surface of the earphone body portion abuts against the second limiting portion 1012 on the inner surface of the upper shell, so that the second limiting portion and the body portion slot jointly limit the earphone.

[0105] In another embodiment of the present 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 limitation of the earphone.

[0106] 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 limitation of the earphone.

[0107] 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.

[0108] The second limiting area in this disclosure can limit the earphone in the vertical direction and also in the horizontal direction. On this basis, a first limiting area is further set. The first limiting area can limit the earphone in the horizontal direction and also 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.

[0109] 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.

[0110] Of course, in other solutions, 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, enabling the user to further see more parts of the earphone through the housing.

[0111] The solution of this embodiment further includes: 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 installation 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.

[0112] 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, it can accommodate tolerances, reduce contact, and avoid scratching the earphone.

[0113] In one embodiment, the earphone matching 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 installation 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, thereby preventing the displacement of the battery part from affecting charging.

[0114] As Figure 13 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.

[0115] In a specific implementation, 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 implementations, this distance can also be other values between 0.2 - 0.5 mm.

[0116] In the solution disclosed herein, the first limiting portion is made of a transparent material, and the surface of the first limiting portion does not abut against the battery portion. This setting can effectively reduce the contact area between the earphone and the first limiting portion, reduce the scratching inside, and improve the durability of the first limiting portion. Moreover, the upper shell of the earphone case in this solution is a transparent shell, so that the details of the earphone can be clearly displayed on the appearance surface.

[0117] In addition, when the earphone is placed in the earphone case, the battery portion will abut against the first limiting portion when the earphone shakes with the earphone case. Since the force conduction does not require the entire surface to bear, the outer surface of the first limiting portion in this solution is set as a curved surface, so that the earphone and the first limiting portion can achieve the limiting of the earphone through point contact or line contact. In this solution, the first limiting portion is set as a convex curved surface, which can reduce the volume of the first limiting portion compared with setting the first limiting portion as a cylinder, thus saving materials.

[0118] The solution of this embodiment further includes: when the upper shell 101 and the lower shell 102 are in a closed state, the first limiting portion 1011 abuts against the inner surface of the lower shell 102 opposite thereto; or the distance between the first limiting portion 1011 and the inner surface of the lower shell 102 opposite thereto is 4 - 6 mm.

[0119] 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 against the surface in the V-shaped area 1026 on the lower shell 102 or not. 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 a closed state, the lower end of the first limiting portion 1011 abuts against the inner surface of the lower shell 102, and the first limiting portion can play a role in supporting the upper shell, so that the upper shell will not collapse when pressed. In another embodiment, in order to save materials, 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 a closed state, the lower end of the first limiting portion 1011 does not need to abut against the inner surface of the lower shell 102, but has a certain distance from the inner surface of the lower shell 102, and this distance can be 4 - 6 mm.

[0120] In a specific embodiment, the distance between the first limiting portion and the inner surface of the lower shell is 5 mm. Of course, in other specific implementation schemes, this distance can also be other values between 4 - 6 mm.

[0121] In this solution, since there is a distance between the first limiting portion and the lower shell, that is to say, the protrusion of the first limiting portion is not too much, which can reduce the stress risk of the first limiting portion during the production of special-shaped injection molding and can also reduce the stress risk of the first limiting portion after production is completed.

[0122] In this solution, since the battery part is arranged 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.

[0123] In the solution disclosed herein, when the user places the earphone in the earphone case, in order to reduce the collision caused when the earphone contacts the installation groove or the abnormal noise generated due to the contact, 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.

[0124] 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.

[0125] 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 any value within 0.2 - 0.5 mm.

[0126] 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.

[0127] In a specific embodiment, the second limiting part can be not 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.

[0128] 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, tolerances can be accommodated, and the collision of the earphone and the abnormal noise generated by the collision can be effectively reduced.

[0129] In the solution provided by this disclosure, on the outer surface of the upper housing, at a position opposite to the first limiting portion, a recess is provided towards the accommodation cavity; the first limiting portion forms a first curved surface, the recess forms 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.

[0130] In the above solution, the first limiting portion extends inwards 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 flat surface, and there is a recessed area in the middle region, which is correspondingly arranged with the first limiting portion. In the solution of this disclosure, since a recess is provided on the upper surface of the upper housing, users can distinguish the upper housing from the lower housing through the sense of touch.

[0131] Specifically, the first limiting portion forms a first curved surface, and the recess forms a second curved surface, where 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.

[0132] 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.

[0133] In addition, in other solutions, the outer surface of the upper housing can be a flat surface, and the first limiting portion protrudes from the inner surface of the upper housing.

[0134] The solution of this embodiment further includes: 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 form a third limiting area for restricting the cylindrical surface of the battery portion.

[0135] Such as Figure 12As shown in the schematic diagram 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 in the direction of the inner surface of the upper housing. In addition, the surfaces of the battery portion in contact with the lowest end of the battery portion groove are 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 together 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.

[0136] 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 the extending end thereof does not abut against the inner surface of the upper housing 101.

[0137] 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 the extending end thereof is flush with the axial section of the battery portion.

[0138] 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.

[0139] 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.

[0140] In some specific solutions, in order to better limit the headphone 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.

[0141] 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 headphone.

[0142] 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. 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 headphone body part or the ear hook to limit the body part or the ear hook. 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 headphone.

[0143] 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.

[0144] Those skilled in the art can understand that, in order to better limit the headphone, the first limiting parts 1011 can be symmetrically arranged on both sides of the body part groove or the ear hook groove 1023.

[0145] 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 headphone can be better limited in the accommodation cavity, preventing its displacement from affecting charging.

[0146] The above content has introduced in detail the limiting structure inside the headphone case. Next, the structure of the headphone case will be introduced in detail.

[0147] As Figure 9 As shown in the schematic diagram of the headphone case, the disclosed headphone case 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 headphone case.

[0148] In the solution disclosed herein, the outer surfaces of the upper housing 101 and the lower housing 102 at the opening and closing area both converge towards the joint surface, thereby forming a groove 103. In addition, catches are provided on the upper housing 101 and the lower housing 102 at the opening and 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.

[0149] 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 and closing area converge towards the joint surface, that is, the thickness of the upper housing 101 and the lower housing 102 at the opening and 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 and closing area does not change, but only the extending direction is changed, that is, the side walls extend towards the accommodation cavity to form a groove 103.

[0150] During use, when closing the earphone case, rotate the upper housing 101 or the lower housing 102 along the rotating shaft to cover 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.

[0151] For the earphone case provided in this disclosure, the groove 103 is provided in the opening and closing area, and the opening and 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 extending length and the extending length of the groove 103 is also long, the user can place the hand in any area of the groove 103 to open the earphone case during use, making the operation more convenient.

[0152] In the solution provided in this disclosure, the area where the groove is located is the opening and closing part. The opening and 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 towards the direction away from the accommodation cavity; the tangent at any position in the opening and closing part or the connection line between any position in the opening and closing part and the end part forms an angle less than or equal to 90° with the joint surface.

[0153] As Figure 14 and 15 shown in the left view and the right view of the earphone case, in a specific implementation, there is an opening and closing part at the opening and closing area. The opening and closing part refers to the area where the groove is located, that is Figure 14The area marked by the dashed line box in the middle. 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°.

[0154] 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 line connecting 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°.

[0155] In the solution provided by this 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 from the area of the outer surface of the side wall of the upper housing 101 farthest from the accommodation cavity to the plane of the joint surface is 3 - 5 mm, and the radius of the arc is 5 - 6 mm.

[0156] 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 from the highest point of the outer surface of the arc to the plane of the joint surface is 3 - 5 mm, and the radius of the arc is 5 - 6 mm.

[0157] In a specific embodiment, the vertical distance from the highest point of the arc-shaped outer surface of the side wall of the upper housing to the plane of the joint surface is 4 mm, and the radius of the arc is 5.3 mm. Of course, in other embodiments, the vertical distance from the highest point of the arc-shaped outer surface of the side wall of the upper housing to 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 of the inward contraction of the arc surface at the joint surface.

[0158] 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 / 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 single-handed opening of the earphone case.

[0159] 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 / closing area is a plane, which 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 and arc-transitionally connected to the inner surface of the side wall.

[0160] 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 making it possible for the user to open the earphone case with one hand. This solution can improve the user experience.

[0161] In another specific implementation, the box body further includes a third side and a fourth side provided at both ends, and the opening / closing area extends from the second side to the third side and the fourth side. That is to say, in this implementation, 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 / closing areas, and the user can also open the box body at the opening / 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 / closing area can also be provided on the second side and the third side, or on the second side and the fourth side.

[0162] In another specific implementation, the outer surfaces of the upper shell 101 and the lower shell 102 are symmetrically arranged along the end 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 side walls of the upper shell 101 and the lower shell 102 are symmetrically arranged arc-shaped. Such a setting not only enables the two shells to form a groove 103 at the opening / 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.

[0163] In the above solution, the first housing is a transparent or semi-transparent 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 connections between the side walls and the top wall of the outer surface of the box disclosed herein are smooth arcs, that is, there are no sharp corners on the outer surface of the box, and the connections between the side walls and the connections between the side walls and the top wall are all arc-shaped. This makes it convenient to place the box in a narrow space such as a pocket of clothing. 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 trapezoidal shape (for example Figure 15 the trapezoid shown by the dashed line box in

[0164] . 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 perception.

[0165] In the solution disclosed herein, the box is formed by injection molding or other methods, and this manufacturing method can reduce stress concentration at the outer edge of the box.

[0166] In the above solution, the upper housing is a transparent or semi-transparent 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 connections between the side walls and the top wall of the outer surface of the earphone box disclosed herein are smooth arcs, that is, there are no sharp corners on the outer surface of the earphone box, and the connections between the side walls and the connections 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 a 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.

[0167] In another specific implementation, 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 by touch, so as to open or close the earphone box more quickly.

[0168] In the solution provided by this disclosure, the inner surface of the side wall of the upper housing 101 is a closed or unclosed smooth circular cylindrical surface; or the inner side surface of the inner wall of the upper housing 101 is a closed or unclosed smooth circular 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.

[0169] In a specific embodiment, the outer surface of the side wall of the upper housing 101 is arc-shaped, the inner surface of the side wall is vertically arranged, and the inner surface of the side wall 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 side walls, and the connections of the inner surfaces of each side wall are arc-shaped transition connections. When the inner surface of the side wall does not need to avoid the rotating shaft, the inner surfaces of the four side walls of the upper housing 101 form a smooth and closed annular cylindrical surface. When the inner surface of the side wall needs to avoid the rotating shaft, at this time, the inner surfaces of the four side walls form an unclosed annular cylindrical surface.

[0170] In the above solution, the upper housing 101 of the earphone case is set as a transparent housing or a semi-transparent housing, so that users can observe the state of the objects placed in the accommodation cavity through the upper housing 101 without opening the earphone case. Also, since the outer surface of the side wall of the upper housing 101 is arc-shaped, this setting method increases the thickness of the box body, makes the first housing 101 stronger, can withstand greater pressure from the top or side of the housing, and also improves the anti-drop performance.

[0171] On the basis that the outer surface of the side wall of the upper housing 101 is arc-shaped, the inner surface is vertically arranged. Therefore, the outer surface and the inner surface of the side wall form a plano-convex lens, which can magnify the items placed in the earphone case and present a clearer visual effect to the user. In addition, when the side walls of the first side and the second side both form plano-convex lenses, a complex visual effect can be formed.

[0172] As Figure 16 As shown in the schematic diagram of the inner surface of the upper housing being an inclined plane, in another specific embodiment, the inner surface of the side wall 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 of 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 plane 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 side walls and the inner surface of the top wall are also arc-shaped transition connections. When the inner surface of the side wall does not need to avoid the rotating shaft, the inner surfaces of the four side walls of the upper housing 101 form a smooth and closed annular inclined plane. When the inner surface of the side wall needs to avoid the rotating shaft, at this time, the inner surfaces of the four side walls form an unclosed annular inclined plane. It should be noted that Figure 16 This is only a schematic diagram to illustrate the situation where the inner surface of the side wall of the upper housing 101 is inclined.

[0173] In another specific embodiment, the inner surface of the side wall 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 that of the outer surface of the side wall. That is to say, in this solution, the inner surface and the outer surface of the side wall 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 side wall does not need to avoid the rotating shaft, the inner surfaces of the four side walls of the upper housing 101 form a smooth closed annular curved surface. When the inner surface of the side wall needs to avoid the rotating shaft, at this time, the inner surfaces of the four side walls form an unclosed annular curved surface.

[0174] In the solution disclosed in the present disclosure, 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 and 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 and closing area by touch, different materials can be used for the outer surface at the opening and closing area and the outer surface on the rotating shaft side during production. Or the outer surface at the opening and closing area and the outer surface on the rotating shaft side are made into different shapes.

[0175] In addition, in the solution disclosed in the present disclosure, 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 an effect of magnification, reduction or distortion of the objects inside the earphone case visually. And the solution disclosed in the present disclosure will utilize the fact that the curved surface causes light to refract at different angles to achieve a special visual effect to design the earphone case.

[0176] Those skilled in the art can understand that when the thickness of the side wall of the upper housing of the earphone case remains unchanged and is perpendicular to the top surface, although refraction will occur 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.

[0177] When 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 an effect of magnification, reduction or distortion of the objects inside the earphone case visually. And the solution disclosed in the present disclosure is to utilize the fact that the curved surface causes light to refract at different angles to achieve a special visual effect to design the earphone case.

[0178] When the earphone is placed in the installation groove, due to the inconsistent distances between the various parts of the earphone and the side wall of the upper housing, a special light and shadow effect will be formed through the curved surface of the side wall of the upper housing. For example, when the user gazes from the opening and closing area of the upper housing towards the direction where the rotating shaft is located, a part of the area of the earphone may disappear or be distorted due to refraction, forming a special visual effect.

[0179] 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 the areas far from the focus. In this way, the earphone can form clear and blurred visual changes, enhancing the visual hierarchy.

[0180] According to the characteristics of the above-mentioned plano-convex lens, important parts of the earphone can be arranged close to the focus, and unimportant parts can be arranged far from the focus. For example, the charging contacts of the earphone are usually arranged on the earphone body part. Therefore, the body part can be arranged close to the focus, so that users can clearly see the shape and location of the body part through the upper shell.

[0181] 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.

[0182] 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.

[0183] Although multiple embodiments of this disclosure have been shown and described herein, it is obvious to those skilled in the art that such embodiments are provided only by way of example. 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 solutions to the embodiments of this 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 alternative solutions within the scope of these claims.
