[0029] With the continuous development of earphone technology, rechargeable earphones that are easy to carry and can be charged at any time have received widespread attention. Rechargeable earphones include earphones and an earphone box, and the earphone box is used to accommodate and charge the earphones. At present, the line connecting the positive charging contact terminal and the negative charging contact terminal of most earphone boxes is parallel to the bearing plane of the earphone box with the earphone receiving slot. In this way, after the earphone is placed in the earphone box, the line connecting the positive charging contact terminal and the negative charging contact terminal of the earphone is also required to be parallel to the bearing plane of the earphone box. However, in order to improve the wearing comfort of the earphones, designers usually make adjustments to the structure of the earphones. In this way, it is easy to cause the line connecting the positive charging contact terminal and the negative charging contact terminal of the earphone to tilt after the earphone is placed in the earphone box, resulting in poor electrical contact between the earphone and the earphone box, which will affect the charging efficiency of the earphone.

[0030] To this end, an embodiment of the present application provides an earphone assembly for improving the adequacy of electrical contact between the earphone and the earphone box, thereby improving the charging efficiency of the earphone.

[0031] Below, refer to Figures 1 to 7 Some embodiments of the present application are described in detail.

[0032] Figure 1 A schematic structural diagram of an earphone assembly in one state provided by some embodiments of the present application; Figure 2 A cross-sectional view of an earphone assembly provided for some embodiments of the present application; Figure 3 A schematic diagram of the structure of headphones provided in some embodiments of the present application; Figure 4 A schematic structural diagram of an earphone assembly in another state provided by some embodiments of the present application; Figure 5 A cross-sectional view of an earphone box of an earphone assembly provided in some embodiments of the present application; Figure 6 A cross-sectional view of an earphone provided in some embodiments of the present application, cut through the ear stem; Figure 7 A schematic structural diagram of another state of the earphone assembly provided in some embodiments of the present application.

[0033] like Figures 1 to 5As shown, the earphone 200 has a positive charging portion 231 and a negative charging portion 232; the earphone box 100 includes a base 130, a positive charging column 122 and a negative charging column 123, the base 130 has a bearing plane 110, at least part of the bearing plane 110 is recessed inward to form an earphone receiving groove 120, a portion of the positive charging column 122 passes through the groove wall of the earphone receiving groove 120 and extends into the earphone receiving groove 120, and the end of the positive charging column 122 extending into the earphone receiving groove 120 is a first end. Part 124, part of the negative charging column 123 passes through the wall of the earphone receiving groove 120 and extends into the earphone receiving groove 120, and the end of the negative charging column 123 extending into the earphone receiving groove 120 is the second end 125, and the line L1 between the first end 124 and the second end 125 intersects with the bearing plane 110. When the earphone 200 is accommodated in the earphone receiving groove 120, the first end 124 contacts the positive charging part 231 and the second end 125 contacts the negative charging part 232.

[0034] See also Figure 5 The connecting line L1 between the first end portion 124 and the second end portion 125 intersects with the bearing plane 110 , and the angle between the two is α, 0<α<180°.

[0035] In the earphone assembly provided in the embodiment of the present application, the line L1 connecting the contact end (first end 124) of the positive charging column 122 and the contact end (second end 125) of the negative charging column 123 is set to intersect with the bearing plane 110, so that the relative positions of the first end 124 and the second end 125 are adapted to the relative positions of the positive charging part 231 and the negative charging part 232 of the earphone 200, so that when the earphone 200 is accommodated in the earphone accommodating slot 120, the first end 124 can fully contact the positive charging part 231, and the second end 125 can fully contact the negative charging part 232, thereby improving the sufficiency of the electrical contact and thus improving the charging efficiency.

[0036] In some embodiments of this application, see Figure 3 The earphone 200 includes a sound-emitting part 210 and an ear handle part 220 connected to the sound-emitting part 210, a positive charging part 231 and a negative charging part 232 are provided on the ear handle part 220, and an acute angle β is formed between the axis A of the sound-emitting part 210 and the axis B of the ear handle part 220.

[0037] In this way, the earphone assembly structure of the present application is ergonomic, so that the earphone 200 can better fit the contours of the ear and head when worn, reducing the pressure and discomfort caused by long-term wearing and improving wearing comfort.

[0038] In some embodiments of the present application, the earphone receiving groove 120 includes a sound-emitting part receiving groove 1201 and an ear handle part receiving groove 1202, the positive charging column 122 and the negative charging column 123 extend into the ear handle part receiving groove 1202, the inner surface of the sound-emitting part receiving groove 1201 is adapted to at least part of the outer contour of the sound-emitting part 210, and the inner surface of the ear handle part receiving groove 1202 is adapted to at least part of the outer contour of the ear handle part 220.

[0039] The inner surface of the sound-emitting part accommodating groove 1201 is adapted to at least part of the outer contour of the sound-emitting part 210, and the inner surface of the ear handle accommodating groove 1202 is adapted to at least part of the outer contour of the ear handle 220, so that the earphone 200 is well limited in the earphone box 100, which improves the sufficiency and stability of the electrical contact, thereby improving the charging efficiency, and reducing the risk of damage caused by shaking or collision, improving the stability of the earphone 200 during storage and carrying, effectively preventing the earphone 200 from sliding or falling in the earphone box 100, and effectively protecting the internal structure of the earphone 200 from damage.

[0040] In some embodiments of the present application, two earphones 200 are provided, and the base 130 forms two earphone receiving slots 120 , and the two earphone receiving slots 120 are distributed in mirror symmetry.

[0041] In this way, the ear handles 220 of the two earphones 200 placed in the earphone box 100 are placed in the same orientation, which helps to simplify the user's action of taking out the two earphones 200 from the earphone box 100 and wearing them on the ears, thereby improving the user experience.

[0042] In some embodiments of this application, see Figure 4 The side of each sound-emitting part 210 close to another sound-emitting part 210 is a first side, and the side away from another sound-emitting part 210 is a second side. Along the direction perpendicular to the supporting plane 110, the projection area of ​​the sound-emitting part 210 on the second side is larger than the projection area on the first side.

[0043] Thus, the structure of the earphone 200 helps match the shape and size of the user's ear, improving the comfort of wearing the earphones. Moreover, storing the two earphones 200 in this manner facilitates the proximity of the ear handles 220 of the two earphones 200 to each other, that is, the ear handle receiving slots 1202 of the two earphone receiving slots 120 are close to each other, thereby reducing the spacing between the positive charging posts 122 and the spacing between the negative charging posts 123 in the two ear handle receiving slots 1202. This shortens the electrical connection lines between the two positive charging posts 122 and the two negative charging posts 123, reducing the space occupied by the lines, facilitating the miniaturization of the earphone box 100, and reducing materials and costs.

[0044] In some embodiments of the present application, Figure 5 and Figure 6 As shown, the positive charging portion 231 includes a first curved surface 233 , and the positive charging portion 231 contacts the first end 124 through the first curved surface 233 ; and / or the negative charging portion 232 includes a second curved surface 234 , and the negative charging portion 232 contacts the second end 125 through the second curved surface 234 .

[0045] The arc-shaped structure can better adapt to the slight position deviation of the earphones and the charging case during the connection process, further improving the stability of the connection.

[0046] In some embodiments of the present application, the first arcuate surface 233 and / or the second arcuate surface 234 is a convex arcuate surface.

[0047] The arc-shaped raised structure can increase the contact surface area, making the pressure distribution more uniform, reducing local wear and stress concentration, improving the stability of the connection and enhancing the charging efficiency.

[0048] In some embodiments of the present application, the first arcuate surface 233 and / or the second arcuate surface 234 is a concave arcuate surface.

[0049] In some embodiments of the present application, the end face of the first end portion 124 is a third curved surface 1241, and the first end portion 124 contacts the positive charging portion 231 through the third curved surface 1241; and / or the end face of the second end portion 125 is a fourth curved surface 1251, and the second end portion 125 contacts the negative charging portion 232 through the fourth curved surface 1251, the positive charging portion 231 contacts the first end portion 124 through the first curved surface 233, and the negative charging portion 232 contacts the second end portion 125 through the second curved surface 234, the first end portion 124 contacts the positive charging portion 231 through the third curved surface 1241, and the second end portion 125 contacts the negative charging portion 232 through the fourth curved surface 1251.

[0050] This curved contact surface can better accommodate slight positional deviations between the earphones and the earphone case during connection, further improving connection stability and reducing the risk of poor contact or short circuits during charging. This helps improve charging efficiency and ensures that the earphones 200 are fully charged quickly. Furthermore, sufficient contact reduces energy loss during charging and improves energy efficiency.

[0051] In some embodiments of the present application, the third arcuate surface 1241 and / or the fourth arcuate surface 1251 is a convex arcuate surface.

[0052] The arc-shaped raised structure can increase the contact surface area, making the pressure distribution more uniform, reducing local wear and stress concentration, improving the stability of the connection and enhancing the charging efficiency.

[0053] In some embodiments of the present application, the third arcuate surface 1241 and / or the fourth arcuate surface 1251 is a concave arcuate surface.

[0054] In some embodiments of the present application, Figure 7 As shown, the earphone 200 has a first magnetic member 240 , and the earphone box 100 further includes a second magnetic member 131 disposed on the base 130 , and the first magnetic member 240 and the second magnetic member 131 attract each other.

[0055] Illustratively, the first magnetic member 240 may be a permanent magnet or an electromagnet, and the second magnetic member 131 may be a permanent magnet or an electromagnet.

[0056] The mutually attractive first magnetic part 240 and the second magnetic part 131 improve the reliability of the earphone 200 in the earphone box 100, improve the reliability of the contact between the first curved surface 233 and the third curved surface 1241, the second curved surface 234 and the fourth curved surface 1251, reduce poor contact during charging, and further improve charging efficiency.

[0057] In some embodiments of the present application, the first magnetic member 240 is disposed close to the positive charging portion 231 and the negative charging portion 232 , and the second magnetic member 131 is disposed close to the positive charging column 122 and the negative charging column 123 .

[0058] The first magnetic member 240 is disposed proximate to the positive charging portion 231 and the negative charging portion 232. The first magnetic member 240 may be in contact with the positive charging portion 231 and the negative charging portion 232, and the contact may be direct or indirect. Alternatively, there may be a gap between the first magnetic member 240 and the positive charging portion 231 and the negative charging portion 232, and the gap is defined as a relatively small preset spacing. In this way, when the first magnetic member 240 and the second magnetic member 131 attract each other, the contact force between the positive charging portion 231 and the positive charging column 122, and the contact force between the negative charging portion 232 and the negative charging column 123, is increased.

[0059] Similarly, the second magnetic member 131 is disposed proximate to the positive charging column 122 and the negative charging column 123. The second magnetic member 131 and the positive charging column 122 and the negative charging column 123 may be in direct or indirect contact. Alternatively, there may be a gap between the second magnetic member 131 and the positive charging column 122 and the negative charging column 123, and the gap is defined as a relatively small set distance. In this way, when the first magnetic member 240 and the second magnetic member 131 attract each other, the contact force between the positive charging column 122 and the positive charging portion 231, and the contact force between the negative charging column 123 and the negative charging portion 232 are increased.

[0060] Through the mutual attraction between the first magnetic member 240 and the second magnetic member 131, the positive charging portion 231 and the positive charging column 122, as well as the negative charging portion 232 and the negative charging column 123, can be automatically docked without manual alignment, thereby improving the convenience and efficiency of use. This reduces the low charging efficiency caused by poor contact or misalignment, ensuring the efficient charging process. Furthermore, by being arranged in close proximity, the contact force between the positive charging column 122 and the positive charging portion 231, as well as the contact force between the negative charging column 123 and the negative charging portion 232, is increased, thereby improving the stability and sufficiency of the contact and thus improving the charging efficiency.

[0061] Specifically, the sound-emitting portion 210 has a sound outlet 211 and a pressure relief and tuning hole 212 . When the earphone is worn, the audio signal is output from the sound outlet 211 to the user's ear canal, and air is inhaled or discharged through the pressure relief and tuning hole 212 .

[0062] In some embodiments of the present application, a portion of the earphone receiving slot 120 protrudes outward to form a positioning protrusion 121, and the positive charging column 122 and the negative charging column 123 pass through the positioning protrusion 121 and extend into the earphone receiving slot 120. A portion of the outer surface of the earphone 200 is recessed inward to form a positioning recess 230, and the positive charging portion 231 and the negative charging portion 232 are arranged in the positioning recess 230. When the earphone 200 is accommodated in the earphone receiving slot 120, the positioning protrusion 121 is inserted into the positioning recess 230.

[0063] The mating connection between the positioning protrusion 121 and the positioning recess 230 improves the alignment accuracy of the earphone case 100 and the earphones 200, thereby increasing the docking accuracy between the first curved surface 233 and the third curved surface 1241, and between the second curved surface 234 and the fourth curved surface 1251, thereby improving charging efficiency. Furthermore, the mating between the positioning protrusion 121 and the positioning recess 230 can reduce the possibility of dust and moisture entering the earphone case 100 and the earphones 200 to a certain extent, thereby enhancing the dust and water resistance of the earphones.

[0064] In some embodiments of the present application, the earphone box 100 further includes an earphone cover 140 , which is connected to the base 130 , and the earphone cover 140 can be opened and closed to close the earphone receiving slot 120 .

[0065] Exemplarily, the earphone cover 140 and the base 130 are hinged, and the earphone cover 140 can close or open the earphone receiving slot 120 by flipping.

[0066] When the earphone 200 is placed in the earphone box 100 , the closing of the earphone cover 140 can effectively prevent the earphone 200 from sliding or falling in the box. At the same time, the earphone cover 140 enhances the dustproof performance of the earphone 200 .

[0067] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application, and they should all be included in the scope of the claims and specification of the present application.
