[0037] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application.

[0038] The earphone is usually used with the earphone box, and the earphone is stored and charged by the earphone box. The earphone box and the earphone are generally connected by a magnet. In the related art, the magnet in the earphone is generally distributed in a single point, which causes uneven force on the earphone and easily shakes in the earphone box, not only causing abnormal noise but also easily colliding.

[0039] In order to solve the above technical problems, please refer to Figures 1-2 The present application provides an earphone 1000 and an earphone assembly, wherein the earphone assembly comprises the earphone 1000 and an earphone box 2000.

[0040] Please refer to Figures 1-3 The earphone box 2000 comprises a box body 2200 and a box cover (not shown in the figure). The box body 2200 is formed with an electrical cavity 2200b for placing electrical elements and a mounting slot 2200a for placing the earphone 1000. The box cover is rotationally connected to the box body 2200 and is used to open or close the mounting slot 2200a, so as to protect the earphone 1000 from being damaged by the external environment when it is placed in the mounting slot 2200a.

[0041] When the earphone 1000 is placed in the installation groove 2200a, the electrical elements of the electrical cavity 2200b can charge the earphone 1000, which can be wireless charging and wired charging. When wired charging is used, the probe of the electrical cavity 2200b extends to the installation groove 2200a, and the earphone 1000 is also provided with a corresponding charging interface or metal probe 201. When the earphone 1000 is placed in the installation groove 2200a, the probe is just connected with the charging interface or the metal probe 201 to achieve power supply.

[0042] Please refer to Figure 3 The earphone 1000 includes a battery compartment 100, a sound production part 200, and an ear hook 300.

[0043] The battery compartment 100 is the power supply part of the earphone 1000, which contains the power supply and related circuit elements, and is used to provide power for the sound production part 200 and other functional components of the earphone 1000. The battery compartment 100 is used to be worn behind the user's earlobe, which can cooperate with the sound production part 200 to ensure the stability of the earphone 1000 when worn. In the embodiment of the present application, the battery compartment 100 includes a first shell 110 and a first magnetic assembly 120. The first shell 110 forms a first cavity, and the first magnetic assembly 120 is arranged in the first cavity. The first shell 110 can prevent external physical impact, dust, moisture, etc. from entering the sound production part 200, thereby ensuring the normal operation of the internal components and prolonging the service life.

[0044] The sound production part 200 is the main audio output part of the earphone 1000, which is generally used to be worn in the user's concha cavity. It contains an audio driving unit (such as a loudspeaker), which is used to convert electrical signals into sound signals and output to the user. In the embodiment of the present application, the sound production part 200 includes a second shell 210 and a second magnetic assembly 220. The second shell 210 forms a second cavity 210a, and the second magnetic assembly 220 is arranged in the second cavity 210a. The second shell 210 can prevent external physical impact, dust, moisture, etc. from entering the sound production part 200, thereby ensuring the normal operation of the internal components and prolonging the service life.

[0045] The ear hook 300 connects the sound-generating part 200 and the battery compartment 100, ensuring a stable connection and mechanical strength between the two. The ear hook 300 allows the earphone 1000 to be securely worn on the user's ears, preventing it from easily falling off even during exercise or activity. The ear hook 300 may include conductive wires and memory metal wires. The conductive wires enable electrical connection between the electrical components of the sound-generating part 200 and the electrical components of the battery compartment 100. The memory metal wires connect the sound-generating part 200 and the battery compartment 100. Due to the super-elastic properties of the memory metal wires, the sound-generating part 200 and the battery compartment 100 tend to move closer to each other, thereby ensuring that the earphone 1000 is securely worn on the user's ears.

[0046] The ear hook 300's shell can be made of thermoplastic elastic materials such as silicone. Silicone is soft and elastic, allowing it to closely conform to the contours of the ear and reduce pressure during prolonged wear. Furthermore, silicone has high abrasion resistance, resisting friction and wear in daily use and extending the lifespan of the ear hook 300.

[0047] The shape memory wire can be titanium shape memory wire, nickel-titanium alloy wire, copper-based shape memory wire (such as copper-zinc alloy, copper-aluminum alloy, etc.) and iron-based shape memory wire (such as iron-manganese alloy, iron-platinum alloy, etc.), etc. This application does not limit the type of shape memory wire.

[0048] The housing 2200 contains multiple third magnetic components 2100, which are magnetically connected to the first magnetic component 120 and the second magnetic component 220 in a one-to-one correspondence. In this way, when the earphone 1000 is placed inside, the battery compartment 100 and the sound-emitting part 200 can be stably attracted inside the earphone housing 2000, ensuring the stability of the earphone 1000.

[0049] Understandably, with the connection provided by the ear hook 300, when the earphone 1000 is placed inside the earphone case 2000, the sound-emitting part 200 and the battery compartment 100 are arranged roughly along the length of the sound-emitting part 200. Therefore, when the second magnetic element 222 is located at one end of the second cavity 210a near or away from the ear hook 300, it helps to provide a balanced magnetic attraction force, reduce the shaking of the earphone 1000 inside the case, improve stability, and reduce the probability of bumps and abnormal noises.

[0050] Furthermore, placing the second magnetic component 220 at one end of the sound-emitting part 200 near or away from the ear hook 300 helps to provide more space for electrical components (such as speakers, microphones, etc.) within the sound-emitting part 200 without affecting the assembly of the sound-emitting part 200, thereby achieving a miniaturized design of the sound-emitting part 200.

[0051] In one embodiment, please refer to Figure 3, the second cavity 210a includes a first region 200a and a second region 200b arranged along the length direction of the sound production part 200, and the second magnetic assembly 220 is installed in the second region 200b, and the second region 200b is closer to the ear hook than the first region 200a.

[0052] It needs to be understood that, since the battery compartment 100 and the sound production part 200 are both provided with other electronic elements, such as the loudspeaker unit in the sound production part 200 and the battery or the signal lamp in the battery compartment 100, generally, a flexible circuit board 202 is arranged in the sound production part 200 to connect the electronic elements in the battery compartment 100 and the sound production part 200, therefore, by arranging the loudspeaker unit in the first region 200a and the flexible circuit board in the second region 200b, the electronic elements in the battery compartment 100 and the electronic elements in the sound production part can be conveniently electrically connected, and by installing the second magnetic assembly 220 in the second region 200b, the space in the sound production part 200 can be fully utilized, so that the structure of the entire sound production part 200 is compact, thereby facilitating the miniaturization design of the entire earphone 1000.

[0053] Further, along the length direction of the sound production part 200, the distance between the two sides of the first region 200a is h1, and the distance between the two sides of the second region 200b is h2, 1≤h1 / h2≤5, wherein h1 / h2 can be 1, 2, 3, or any value between 5 or above, by the ratio of h1 / h2 in the appropriate range, the space inside the second cavity 210a can be more reasonably distributed, the installation of the loudspeaker unit 230 and the flexible circuit board 202 can be simultaneously satisfied, so that the second magnetic assembly 220 does not occupy other space, and the structure of the entire sound production part 200 is compact, thereby facilitating the miniaturization design of the entire earphone 1000.

[0054] In an embodiment, please refer to Figure 4 The second magnetic assembly 220 includes a plurality of magnetic pieces, and the plurality of magnetic pieces are distributed at intervals, since the second cavity 210a is the cavity of the sound production part 200, and the sound production part 200 generally includes the loudspeaker unit 230, therefore, the weight of the sound production part 200 is large, by arranging the plurality of magnetic pieces distributed at intervals, the stable adsorption of the sound production part 200 can be ensured, and the sound production part 200 is prevented from moving or shaking in the box, and the stability of the sound production part 200 can also protect the precise elements inside the sound production part 200, and avoid damage due to vibration or collision.

[0055] When the plurality of magnetic pieces are distributed at intervals in the sound production part 200, a plurality of stable magnetic attraction points can be formed with the second magnetic assembly 222 in the earphone box 2000, and the magnetic attraction points can jointly act on the earphone 1000 to ensure the stable connection of the earphone 1000 in the earphone box 2000. Even under external force, the earphone 1000 is not easy to fall off or shake, thereby ensuring the reliability of the magnetic attraction connection.

[0056] In addition, since the plurality of magnetic members are spaced apart, the magnetic force can be uniformly distributed, and the user can smoothly take out the earphone 1000.

[0057] Please refer to Figure 4 On the basis of the previous embodiment, the sound generating part is further provided with a second magnetic member 222, and the earphone box is provided with a fourth magnetic assembly 2300, which is magnetically connected with the second magnetic member 222, so as to further increase the magnetic attraction between the sound generating part 200 and the earphone box 2000. The plurality of magnetic members include two first magnetic members 221, the center points of the two first magnetic members 221 and the center point of the second magnetic member 222 have the same straight-line distance, and the two first magnetic members 221 are arranged along the width direction of the sound generating part 200.

[0058] That is, the center points of the two first magnetic members 221 and the center point of the second magnetic member 222 form a stable isosceles triangle structure, which ensures that the magnetic connection of the earphone 1000 in the earphone box 2000 is more balanced. The balanced magnetic force distribution helps to reduce the shaking of the earphone 1000 in the box and improve the stability.

[0059] In addition, the two first magnetic members 221 are arranged along the width direction of the sound generating part 200, which can make the sound generating part 200 bear force uniformly, and the user can smoothly take and place the earphone 1000.

[0060] Furthermore, the sound generating part 200 further includes a barrier (not shown in the figure) and a loudspeaker unit 230.

[0061] The barrier is arranged in the second cavity 210a, that is, the barrier can be used as a structural support inside the sound generating part 200, which enhances the stability and durability of the whole, that is, it can prevent the internal components from loosening or being damaged due to external impact or vibration. In addition, the barrier can also divide the second cavity 210a into a first sub-cavity 211a and a second sub-cavity 212a, the loudspeaker unit 230 is arranged in the first sub-cavity 211a, and the pickup unit is arranged in the second sub-cavity 212a. By means of the barrier, the pickup unit and the loudspeaker unit 230 can be separated, which helps to more accurately capture the sound of the speaker and reduce the interference of environmental noise, and helps to improve the clarity and accuracy of the call.

[0062] It should be understood that the first sub-cavity 211a and the second sub-cavity 212a are not completely separated, and a circuit board is generally arranged in the second cavity 210a. The circuit board is located at the end of the second cavity 210a and extends along the length direction of the sound generating part 200, and the circuit board spans the first sub-cavity 211a and the second sub-cavity 212a.

[0063] The horn unit 230 is the core component of the sound production part 200, responsible for converting electrical signals into sound signals. It contains key components such as the diaphragm, magnet, etc., which vibrate to produce sound and propagate outward.

[0064] In the embodiment of the present application, the first magnetic member 221 is arranged in the second sub-cavity 212a, and the second magnetic member 222 is arranged in the front cavity. Since the front cavity is the part of the horn unit 230 directly facing the external environment, and when the earphone 1000 is placed in the mounting groove 2200a, the front cavity is also closer to the groove bottom of the mounting groove 2200a, therefore, by arranging the second magnetic member 222 in the front cavity, the magnetic attraction effect with the third magnetic assembly 2100 in the earphone box 2000 can be enhanced, that is, the magnetic attraction stability of the sound production part 200 in the earphone box 2000 is enhanced.

[0065] The second sub-cavity 212a does not place the horn unit 230, so there is enough space in the second sub-cavity 212a to facilitate the arrangement of the first magnetic member 221. It should be understood that in the embodiment of the present application, the second sub-cavity 212a also has a metal probe 201 for charging and a flexible circuit board 202, so the first magnetic member 221 is arranged on the side in the second sub-cavity 212a. In this way, the space in the second sub-cavity 212a can be fully utilized, making the sound production part 200 small in size. In addition, due to the stability of the earphone 1000 adsorption, the contact position of the metal probe 201 of the earphone 1000 and the probe of the earphone box 2000 is appropriate when the earphone 1000 is charging, avoiding poor contact.

[0066] Since the second magnetic member 222 is arranged in the front cavity, that is, the second magnetic member 222 occupies the space of the horn unit 230. By arranging the second magnetic member 222 directly in the space of the horn unit 230, the overall space of the earphone 1000 can be significantly saved. This is particularly important for the design of small and light earphones 1000, making the earphone 1000 more miniaturized, thereby facilitating carrying and use.

[0067] Please refer to Figures 2-4 In an embodiment of the present application, when the earphone 1000 is placed in the mounting groove 2200a, the second magnetic assembly 220 is arranged at one end of the second cavity 210a close to the groove bottom of the mounting groove 2200a. In this way, the second magnetic assembly 220 can form a stronger magnetic attraction force with the corresponding third magnetic assembly 2100 in the earphone box 2000, which can ensure that the earphone 1000 can be quickly and stably adsorbed in the earphone box 2000 when placed, preventing the earphone 1000 from falling off or shifting due to external forces (such as vibration, shaking), that is, reducing the probability of noise and bumping.

[0068] In addition, by arranging the second magnetic assembly 220 at one end of the second cavity 210a adjacent to the bottom of the mounting groove 2200a, the second cavity 210a has sufficient space to install the loudspeaker unit 230 and other electrical components, thereby optimizing the use of space and miniaturizing and lightening the sound production part 200.

[0069] It can be understood that the third magnetic assembly 2100 located in the electrical cavity 2200b can also be located at one end of the electrical cavity 2200b facing the earphone 1000. In this way, it can also form a stronger magnetic attraction with the second magnetic assembly 220 in the earphone 1000, thereby improving the stability of the earphone 1000 placed in the mounting groove 2200a. In addition, since the third magnetic assembly 2100 is also located at one end of the electrical cavity 2200b facing the earphone 1000, the electrical cavity 2200b has sufficient space to arrange electrical components such as power supply, thereby making the entire earphone box 2000 compact.

[0070] Please refer to Figure 3 In an embodiment of the present application, the first magnetic assembly 120 is arranged at one end of the battery compartment 100 away from the ear hook 300. In this way, the battery compartment 100 has sufficient space to install electrical components such as power supply, thereby making the entire battery compartment 100 compact and facilitating the miniaturization design of the entire earphone 1000.

[0071] In addition, by arranging the first magnetic assembly 120 at one end of the battery compartment 100, the first magnetic assembly 120 can be closer to the third magnetic assembly 2100 in the electrical cavity 2200b, thereby enhancing the magnetic attraction and ensuring that the battery compartment 100 is stably attached in the earphone box 2000.

[0072] In an embodiment of the present application, the box body 2200 forms an electrical cavity 2200b, and the electrical cavity 2200b is provided with a battery 2002. When the earphone 1000 is placed back in the charging box, the battery 2002 will charge the earphone 1000. The charging probe is opened on the box body 2200 and electrically connected with the battery 2002, so that the external power supply supplies power to the battery 2002. The electrical cavity 2200b is also provided with a circuit board 2001, which integrates a battery management module for controlling the charging and discharging process of the battery 2002.

[0073] Considering the miniaturization and lightening design of the earphone box 2000, a plurality of third magnetic assemblies 2100 are arranged at the edge of the electrical cavity 2200b. In this way, there is sufficient space in the middle to install the circuit board 2001 and the battery 2002. It can be understood that the circuit board 2001 can also be provided with a relief to allow the third magnetic assembly 2100 to extend out, thereby making the entire earphone box 2000 compact and more miniaturized.

[0074] Further, in the embodiments of the present application, referring to Figures 5-6 The electric appliance cavity 2200b is provided with a plurality of positioning grooves 2200c, and the plurality of third magnetic components 2100 are installed in the plurality of positioning grooves 2200c one by one. The design of the positioning grooves 2200c can ensure that the third magnetic components 2100 can be accurately placed at the predetermined positions during installation.

[0075] The third magnetic components 2100 can be installed in the positioning grooves 2200c by embedding or by being bonded with glue. Therefore, the positioning grooves 2200c provide additional support and fixation for the third magnetic components 2100, so that the third magnetic components 2100 are not easy to loosen or fall off after installation, and the stability of magnetic attraction is ensured.

[0076] In the embodiments of the present application, the first magnetic component 120, the second magnetic component 220, and the third magnetic component 2100 are all magnet structures. The first magnetic component 120 in the earphone 1000 can be installed by embedding or bonding with a support, which is not limited here. It is necessary to ensure that the earphone 1000 is placed in the installation groove 2200a, and the first magnetic component 120 and the second magnetic component 220 in the earphone 1000 correspond to the second magnetic component 220 in the earphone box 2000. In this way, the stability of the magnetism can be ensured, so that the earphone 1000 is not easy to shake in the earphone box 2000, and the probability of noise and collision is reduced.
