[0004] This application provides an earphone, which includes two earphone units and a back-hook assembly. Each earphone unit includes a battery housing and a first mating member disposed on the battery housing. The back-hook assembly includes a back hook and two connecting terminals respectively connected to both ends of the back hook. Each connecting terminal has a mounting groove and includes a second mating member. A portion of the battery housing of each earphone unit is inserted into the mounting groove of one of the connecting terminals, so that the first mating member and the second mating member are magnetically attracted to each other, thereby enabling the connecting terminal to restrict the radial position of the earphone unit relative to the connecting terminal.

[0005] In some embodiments, the battery case has a battery compartment, and the first mating member is disposed within the battery compartment; the battery case has a first mating surface that contacts the bottom wall of the mounting groove, and a portion of the battery case is disposed in the mounting groove in an installed state, with the first mating member and the second mating member disposed on opposite sides of the first mating surface.

[0006] In some embodiments, the earphone unit further includes a circuit board and a battery disposed within the battery compartment. In the insertion direction of the battery case, the battery is located on the side of the first mating member opposite to the first mating surface, and the circuit board and the first mating member are arranged side by side in a direction perpendicular to the insertion direction of the battery case.

[0007] In some embodiments, the connecting terminal includes a first mounting portion, a second mounting portion, and a connecting shell. The first mounting portion has the mounting groove. The second mounting portion is located on the side of the first mounting portion away from the opening of the mounting groove, and the second mounting portion is mounted on the first mounting portion. The first mounting portion and the second mounting portion together form a mating cavity for accommodating the second mating member. The second mounting portion is connected to the rear hanger. The connecting shell has a receiving cavity, and both the first mounting portion and the second mounting portion are disposed in the receiving cavity.

[0008] In some embodiments, the outer peripheral wall of the battery casing includes a first mating surface and a second mating surface. The first mating surface contacts the bottom wall of the mounting groove, and the second mating surface is disposed along the periphery of the first mating surface and connected to the first mating surface; wherein the second mating surface contacts the side wall of the mounting groove.

[0009] In some embodiments, two connecting terminals are arranged side by side along a preset direction, and a clamping space for clamping the user's head is formed between the two connecting terminals and the rear hanger; wherein, in the installed state where a portion of the battery case is located in the mounting slot, the preset direction is perpendicular to the insertion direction of the battery case; the rear hanger includes a shaping member, the two ends of which are respectively connected to the two connecting terminals, and the shaping member is used to maintain the clamping space between the two connecting terminals and the rear hanger.

[0010] In some embodiments, the shaping component includes a first shaping section and two second shaping sections, the two second shaping sections being respectively connected to both ends of the first shaping section, and each second shaping section being connected to a connecting terminal, wherein the second shaping section is bent relative to the first shaping section so that the mounting groove of the connecting terminal faces a direction perpendicular to the preset direction.

[0011] In some embodiments, in the installation state where a portion of the battery housing is disposed in the mounting groove, the second shaping segment adjacent to the connecting terminal is arranged parallel to the insertion direction of the battery housing.

[0012] In some embodiments, the rear hanger further includes an outer skin that covers the periphery of the shaping element.

[0013] In some embodiments, the earphone unit further includes a speaker housing and a connecting bridge, with the two ends of the connecting bridge connected to the speaker housing and the battery housing, respectively; wherein, an ear clamping space is formed between the connecting bridge and the speaker housing for clamping the user's ear, and the end of the battery housing away from the connecting bridge is inserted into the mounting slot.

[0014] According to an embodiment of this application, a portion of the battery casing of the earphone unit is inserted into the mounting groove of the connecting terminal. A detachable connection between the earphone unit and the rear-hook assembly is achieved through the magnetic engagement of a first and a second mating component. The earphone unit can be used independently or in combination with the rear-hook assembly, allowing users to freely switch the usage mode of the earphone unit according to their needs in sports or daily life. Furthermore, based on the magnetic engagement that establishes a connection between the earphone unit and the connecting terminal, the sidewall of the mounting groove constrains the radial movement of the earphone unit. This makes the connection between the battery casing and the connecting terminal more stable. When the earphone unit and the rear-hook assembly are used together, the connection position can resist the impact force generated by the user's vigorous activities, resulting in better earphone wearing stability and helping to reduce the risk of the earphone falling off during sports activities.

[0025] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] Open-back headphones are a type of headphone design that doesn't go into the ear, allowing external sound to enter and enabling users to better perceive their surroundings, thus avoiding some potential accident risks. The inventors discovered that the stability of open-back headphones relies on the natural support of the ear, making them prone to falling out when the user's head moves frequently. Therefore, in scenarios such as sports, fitness, and outdoor adventures, open-back headphones are prone to frequent falls due to insufficient stability, not only interrupting the user's activities but also potentially causing damage to the headphones. Based on this, this application provides a type of headphone.

[0028] Please see Figures 1-2 The earphone 1 of this application embodiment includes two earphone units 10 and a back-hook assembly 20. Each earphone unit 10 includes a battery housing 11 and a first mating member 12 disposed on the battery housing. The back-hook assembly 20 includes a back hook 21 and two connecting terminals 22 respectively connected to both ends of the back hook 21. Each connecting terminal 22 has a mounting groove 220 and includes a second mating member 221. A portion of the battery housing 11 of each earphone unit 10 is inserted into the mounting groove 220 of one of the connecting terminals 22, so that the first mating member 12 and the second mating member 221 are magnetically attracted together. Thus, the connecting terminal 22 can restrict the radial position of the earphone unit 10 relative to the connecting terminal 22.

[0029] In this embodiment, the battery casing 11 of the earphone unit 10 is plugged into the mounting slot 220 of the rear-hook assembly 20, and a detachable connection between the earphone unit 10 and the rear-hook assembly 20 is achieved through magnetic attraction. The earphone unit 10 can be used independently or in combination with the rear-hook assembly 20. Users can freely switch the usage mode of the earphone unit 10 according to their needs in sports or daily life. Furthermore, when the earphone unit 10 and the rear-hook assembly 20 are used together, the magnetic attraction provides an attractive force, and the sidewall of the mounting slot 220 constrains the radial movement of the earphone unit 10, thereby suppressing lateral displacement and torsion that may occur when the earphone unit 10 is subjected to external impact. In actual use, the rear-hook assembly is worn on the user's head, and a stable connection is formed between the battery casing and the connecting terminal. During exercise, the earphone 1 can maintain a stable wearing state with a low risk of falling off.

[0030] In this embodiment, the magnetic adsorption connection between the first mating component 12 and the second mating component 221 can be achieved in various ways. One of the first mating component 12 and the second mating component 221 can be a magnetic metal component (e.g., iron, cobalt, nickel, or any two or an alloy of these three), and the other can be a magnet. Alternatively, both the first mating component 12 and the second mating component 221 can be magnets. For example, the first mating component 12 can be a magnetic metal component, and the second mating component 221 can be a magnet; or the first mating component 12 can be a magnet, and the second mating component 221 can be a magnetic metal component. Through this magnetic adsorption connection, the wear on the battery casing 11 and the connecting terminal 22 is relatively low, contributing to the stability and reliability of the product during long-term use.

[0031] In some embodiments, the battery housing 11 has a battery compartment 110, and a first mating member 12 is disposed within the battery compartment 110. The battery housing 11 has a first mating surface 11A that contacts the bottom wall of the mounting groove 220. In the installation state where a portion of the battery housing 11 is disposed in the mounting groove 220, the first mating member 12 and the second mating member 221 are disposed on opposite sides of the first mating surface 11A. The first mating member 12 and the second mating member 221 are disposed opposite each other along the insertion direction X of the battery housing 11 and are spaced relatively close together, so that the magnetic force formed between them is large, which can effectively limit the position of the earphone unit 10 relative to the connection terminal 22 in the insertion direction X.

[0032] In actual assembly, the first mating part 12 is set in the battery compartment 110 corresponding to the first mating surface 11A, and the second mating part 221 is set in the bottom wall of the mounting groove 220. After the battery case 11 is inserted into the mounting groove 220, the first mating part 12 and the second mating part 221 are magnetically engaged, and the first mating surface 11A is in contact with the bottom wall of the mounting groove 220.

[0033] At least a portion of the bottom wall surface of the mounting groove 220 matches the outer contour of the battery casing 11. (See attached image.) Figure 3 The first mating surface 11A is a convex arc surface, and a portion of the bottom wall surface of the mounting groove 220 is a concave arc surface. The first mating surface 11A and the bottom wall surface of the mounting groove 220 form a surface contact, effectively suppressing slippage caused by instantaneous impact and further enhancing the connection stability between the battery housing 11 and the connecting terminal 22. Optionally, all the bottom walls of the mounting groove 220 match the first mating surface 11A and form complementary coupling, resulting in a stable connection between the battery housing 11 and the connecting terminal 22.

[0034] In some embodiments, the outer peripheral wall of the battery casing 11 includes a first mating surface 11A and a second mating surface 11B. The first mating surface 11A contacts the bottom wall of the mounting groove 220, and the second mating surface 11B extends around the first mating surface 11A and is connected to the first mating surface 11A. The second mating surface 11B contacts the side wall of the mounting groove 220, meaning the side wall of the mounting groove 220 radially covers a portion of the battery casing 11. When the second mating surface 11B is a non-rotational curved surface, the radial coverage of the side wall of the mounting groove 220 helps suppress the lateral displacement and rotational tendency of the battery casing 11, while increasing the contact area, thereby mitigating the risk of failure due to excessive local stress.

[0035] Please see Figures 3-4 The earphone unit 10 also includes a circuit board 13 and a battery 14 disposed within the battery compartment 110. The circuit board 13 and the battery 14 are electrically connected. In the insertion direction X of the battery housing 11, the battery 14 is located on the side of the first mating member 12 facing away from the first mating surface 11A, and the circuit board 13 and the first mating member 12 are arranged side by side in a direction perpendicular to the insertion direction X of the battery housing. In this way, by planning the arrangement of the first mating member 12, the circuit board 13, and the battery 14 within the battery compartment 110, the first mating member 12 is disposed at the end of the battery compartment 110 facing the connection terminal 22, while the components are compactly arranged, reducing unnecessary space waste.

[0036] In some embodiments, the insertion direction X of the battery housing 11 is parallel to the length direction of the battery 14. The battery housing 11 includes a bottom shell 111 and a top shell 112. The top shell 112 is fitted onto the bottom shell 111 and together with the bottom shell 111, forms a battery compartment 110. The first mating member 12, the circuit board 13, and the battery 14 are all mounted on the bottom shell 111. The top shell 112 is fitted onto the bottom shell 111 in a direction perpendicular to the length direction of the battery 14. Thus, the opening area of ​​the bottom shell 111 is relatively large, which facilitates the installation and arrangement of the first mating member 12, the circuit board 13, and the battery 14.

[0037] Please see Figure 5 The connecting terminal 22 includes a first mounting portion 222, a second mounting portion 223, and a connecting shell 224. The connecting shell 224 has a receiving cavity, in which both the first mounting portion 222 and the second mounting portion 223 are located. The first mounting portion 222 has a mounting groove 220 for mounting the battery case 11. The second mounting portion 223 is located on the side of the first mounting portion 222 away from the opening of the mounting groove 220, and is connected to the rear hanger 21. The second mounting portion 223 is mounted on the first mounting portion 222, and the first mounting portion 222 and the second mounting portion 223 together form a mating cavity for accommodating the second mating member 221.

[0038] Optionally, the first mating member 12 is disposed on the wall surface of the first mounting portion 222 facing away from the bottom wall surface of the mounting groove 220. For example, the first mating member 12 is directly bonded to the wall surface of the first mounting portion 222 facing away from the mounting groove 220. Alternatively, the first mounting portion 222 may also have a first groove body, with the first groove body and the mounting groove being disposed opposite to each other along the insertion direction X of the battery case 11, and the first mating member 12 being disposed in the first groove body.

[0039] Please continue reading. Figure 5 Two connecting terminals 22 are arranged side by side along a preset direction, and a clamping space for holding the earphone 1 on the user's head is formed between the two connecting terminals 22 and the rear hook 21. In the installed state where a portion of the battery housing 11 is located in the mounting slot 220, the preset direction is perpendicular to the insertion direction X of the battery housing 11. Thus, when the earphone unit 10 and the rear hook assembly 20 are used together, the rear hook assembly 20 can clamp onto the user's head, and the clamping force of the rear hook assembly 20 further enhances the wearing stability of the earphone 1, allowing the user to wear and use the earphone 1 during vigorous activities.

[0040] The rear hanger 21 includes a shaping component 211, with its two ends connected to two connecting terminals 22. The shaping component 211 can change its shape under force and return to its original position when the external force is removed. The shaping component 211 has a certain degree of stability, allowing the rear hanger 21 to be maintained more stably in a certain state. Therefore, the shaping component 211 is used to maintain the clamping space between the two connecting terminals 22 and the rear hanger 21.

[0041] Optionally, the shaping component 211 is made of shape memory metal, which can support the shape of the rear hanger 21. For example, the shaping component 211 can be one or a combination of titanium wire, nickel-titanium alloy wire, copper-zinc alloy wire, copper-aluminum-nickel alloy wire, copper-molybdenum-nickel alloy wire, or copper-gold-zinc alloy wire.

[0042] In some embodiments, the shaping component 211 includes a first shaping segment 201 and two second shaping segments 202, which are respectively connected to both ends of the first shaping segment 201. Each second shaping segment 202 is connected to a connecting terminal 22. The first shaping segment 201 is arc-shaped to adapt to the user's head shape, providing a more comfortable wearing experience. The second shaping segments 202 are bent relative to the first shaping segment 201 so that the mounting groove 220 of the connecting terminal 22 faces a direction perpendicular to a preset direction. In actual use, the earphone unit 10 is worn on the user's ear, and the battery housing 11 is located on the back of the ear. The mounting groove 220 of the connecting terminal 22 faces the battery housing 11 of the earphone unit 10, facilitating user installation. Compared to horizontal installation, the connecting terminal 22 is installed from bottom to top on the battery housing 11, which better conforms to the shape of the ear, thereby reducing the feeling of a foreign object.

[0043] In some embodiments, in the installation state where a portion of the battery housing 11 is disposed in the mounting groove 220, a second shaping segment 202 adjacent to the connecting terminal 22 is arranged parallel to the insertion direction X of the battery housing 11. Optionally, the second shaping segment 202 may have a multi-segment bent structure, such as... Figure 5 As shown, the second shaping section 202 includes three straight segments that are smoothly connected, and the extension directions of adjacent straight segments are set at an angle so that the straight segment adjacent to the connecting terminal 22 extends along the insertion direction X of the battery case 11. Optionally, the second shaping section 202 can also adopt a combination of curved segments and straight segments, wherein the straight segment extends along the insertion direction X of the battery case 11 and is connected to the connecting terminal 22, and the curved segment extends from the straight segment to the first shaping section 201.

[0044] In some embodiments, the rear hanger 21 further includes an outer skin 212, which covers the outer periphery of the shaping member 211. The outer skin 212 may be made of an elastic material. For example, the outer skin 212 may be made of an elastic material such as silicone, thermoplastic polyurethane elastomer, thermoplastic elastomer or fluoropolymer, so that the outer skin 212 and the shaping member 211 can deform synchronously when the rear hanger 21 is subjected to force.

[0045] In this embodiment, the rear-hook assembly 20 is not only structurally robust and highly reliable, but also does not have any additional electronic components (such as power interface, buttons, earpiece, etc.) on the rear-hook piece 21, which helps to reduce the pressure on the user's head when wearing it. The rear-hook assembly 20 has a simple structure and is lightweight, which reduces the wearing burden of the earphone 1 in sports scenarios and ensures the user's comfort during long-term use.

[0046] The earphone unit 10 can be a separate earphone, for example, the earphone unit 10 can be an ear hook earphone. The earphone 1 can be used independently, is small in size, and is easy to carry and store. The earphone 1 can also be connected to the back hook component 20 so that the user can hang the earphone 1 around their neck. It is suitable for scenarios where the earphone 1 needs to be worn for a long time or needs to be frequently used.

[0047] In some embodiments, the earphone unit 10 further includes a speaker housing 15 and a connecting bridge 16, with both ends of the connecting bridge 16 connected to the speaker housing 15 and the battery housing 11, respectively. An ear-clamping space is formed between the connecting bridge 16 and the speaker housing 15 to hold the user's ear, and the end of the battery housing 11 away from the connecting bridge 16 is inserted into a mounting slot 220. In actual manufacturing, the connecting bridge 16 and the battery housing 11 can be separate for easy maintenance and disassembly, or the connecting bridge 16 and the battery housing 11 can be integrally formed to make the surface of the earphone unit 10 smoother and improve wearing comfort; for example, the connecting bridge 16 and the bottom shell 111 of the battery housing 11 can be integrally formed.

[0048] In some embodiments, the headphone unit 10 further includes a speaker 17 and a control component 18 disposed within a speaker housing 15. The control component 18 is electrically connected to the speaker 17, and the control component 18 is electrically connected to a circuit board 13 within a battery housing 11 via a connecting wire passing through a connecting bridge 16. Thus, the battery 14 can supply power to the control component 18 and the speaker 17, and the control component 18 can control the operation of the battery 14 and the speaker 17 based on user commands.

[0049] The earphone unit 10 also includes a first charging terminal 19, which is installed on the speaker housing 15 and electrically connected to the control component 18. In actual use, the earphone case is provided with a second charging terminal. After the earphone unit 10 is placed in the earphone case, the first charging terminal 19 can be electrically connected to the second charging terminal so that the earphone case can supply power to the earphone unit 10.
