[0042] 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.

[0043] Earphones are usually used with an earphone case for storage and charging. The earphone case and earphones are generally connected by magnets. However, in related technologies, the magnets are usually distributed at a single point inside the earphones, which causes uneven force on the earphones and makes them prone to shaking in the earphone case. This not only causes abnormal noises but also makes them more susceptible to bumps and knocks.

[0044] To resolve the above technical issues, please refer to Figure 1 This application proposes an earphone 1 and an earphone assembly, wherein the earphone assembly includes the earphone 1 and the earphone case 2.

[0045] Please see Figures 1-3 The headphone case 2 includes a case body 210 and a case cover (not shown in the figure). The case body 210 has an electrical cavity 210a for placing electrical components and a mounting slot 2a for placing the headphone 1. The case cover is rotatably connected to the case body 210 and is used to open or close the mounting slot 2a, thereby protecting the headphone 1 from damage by the external environment when it is placed in the mounting slot 2a.

[0046] When the earphone 1 is placed in the mounting slot 2a, the electrical components of the electrical cavity 210a can charge the earphone 1. Specifically, wireless charging and wired charging can be used. When using wired charging, the probe of the electrical cavity 210a extends into the mounting slot 2a, and the earphone 1 is also provided with a corresponding charging interface or metal probe. When the earphone 1 is placed in the mounting slot 2a, the probe is exactly connected to the charging interface or the metal probe to achieve power supply.

[0047] Please see Figures 1-3 The headphone 1 includes a sound-producing part 110.

[0048] The sound-producing part 110 is the main audio output part of the earphone 1. It is generally worn inside the user's ear canal. It contains an audio driver unit (such as a speaker) to convert electrical signals into sound signals and output them to the user.

[0049] The sound-emitting part 110 has a first cavity 110a, and the first cavity 110a is provided with a plurality of first magnetic elements 111. Please refer to [link / reference]. Figure 3 The electrical cavity 210a of the housing 210 is provided with a plurality of second magnetic elements 211. The plurality of first magnetic elements 111 correspond one-to-one with the plurality of second magnetic elements 211 in the housing 210 and are magnetically connected. There can be two, three, four, etc., of the first magnetic elements 111, and no restrictions are imposed here. Correspondingly, there can also be two, three, four, etc., of the second magnetic elements 211. In this embodiment, the earphone 1 can be magnetically attracted to the mounting groove through multi-point adsorption, thereby ensuring the stability of the adsorption. This reduces the shaking of the earphone 1 in the earphone case 2 when the earphone case 2 moves with the user, which further reduces the probability of abnormal noise and bumps, and improves the service life of the earphone 1 and the earphone case 2.

[0050] In this application, the earphone 1 can be an ear-hook earphone or a non-ear-hook earphone. In the ear-hook earphone, the sound-emitting part 110 (speaker) and the battery 121 can be in one compartment or in two compartments. In this application embodiment, the earphone 1 is an ear-hook earphone and the sound-emitting part 110 (speaker) and the battery 121 are in two compartments for illustrative purposes.

[0051] Please see Figures 1-3 The earphone 1 also includes a battery compartment 120 and an ear hook 130.

[0052] The battery compartment 120 is the power supply part of the earphone 1. It contains a power source and related circuit components to provide power to the sound-generating part 110 and other functional components of the earphone 1. The battery compartment 120 is worn behind the user's earlobe and can work together with the sound-generating part 110 to ensure the stability of the earphone 1 when worn.

[0053] The ear hook 130 connects the sound-generating part 110 and the battery compartment 120, ensuring a stable connection and mechanical strength between the two. The ear hook 130 allows the earphone 1 to be securely worn on the user's ear, and it is not easy to fall off even during exercise or activity. The ear hook 130 may include conductive wires and memory metal wires. The conductive wires enable electrical connection between the electrical components of the sound-generating part 110 and the electrical components of the battery compartment 120. The memory metal wires connect the sound-generating part 110 and the battery compartment 120. Due to the super-elastic properties of the memory metal wires, the sound-generating part 110 and the battery compartment 120 tend to move closer to each other, thereby enabling the earphone 1 to be securely worn on the user's ear.

[0054] The ear hook 130'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. In addition, silicone has high abrasion resistance, resisting friction and wear in daily use and extending the lifespan of the ear hook 130.

[0055] 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.

[0056] The battery compartment 120 has a second cavity 120a, and the ear hook 130 has a third cavity 130a. A third magnetic element 122 is provided within both the second cavity 120a and the third cavity 130a. (Please refer to...) Figure 4 The electrical cavity 210a of the housing 210 is provided with a plurality of fourth magnetic elements 212, and a plurality of third magnetic elements 122 correspond one-to-one with the plurality of fourth magnetic elements 212 in the housing 210 and are magnetically connected. In this embodiment, the battery compartment 120, ear hook 130 and sound-emitting part 110 can all be magnetically attracted in the mounting groove 2a, thereby ensuring the stability of the attraction. When the earphone case 2 moves with the user, the possibility of the battery compartment 120, ear hook 130 and sound-emitting part 110 shaking in the earphone case 2 is reduced, and the possibility of the earphone 1 shaking as a whole in the earphone case 2 is also reduced, which can also reduce the probability of abnormal noise and bumps.

[0057] Please see Figures 2-3 Furthermore, the sound-emitting part 110 includes a housing 112, a partition, and a speaker unit 113.

[0058] The outer shell 112 is the outermost layer of the sound-emitting part 110. A first cavity 110a is formed inside the outer shell 112. The speaker unit 113 is located inside the first cavity 110a. The outer shell 112 protects the components inside the first cavity 110a and prevents external physical impacts, dust, moisture and other substances from entering the sound-emitting part 110, thereby ensuring the normal operation of the internal components and extending their service life.

[0059] At this time, the housing 112 provides the necessary support structure for the sound-emitting part 110, so that it can maintain a stable shape and size, and can ensure that the speaker unit 113 can maintain the correct position and posture during the sound-emitting process, thereby outputting high-quality sound.

[0060] A partition (not shown in the figure) is disposed within the first cavity 110a. This partition serves as a structural support for the internal structure of the sound-emitting part 110, enhancing overall stability and durability. It prevents internal components from loosening or being damaged due to external impacts or vibrations. Furthermore, the partition divides the first cavity 110a into a first sub-cavity 110a1 and a second sub-cavity 110a2. The speaker unit 113 is disposed within the first sub-cavity 110a1, while the pickup unit is disposed within the second sub-cavity 110a2. The partition separates the pickup unit from the speaker unit 113, helping to more accurately capture the speaker's voice and reduce environmental noise interference, thus improving call clarity and accuracy.

[0061] In the embodiments of this application, at least one first magnetic element 111 is disposed in the front cavity and at least one first magnetic element 111 is disposed in the second sub-cavity 110a2. That is, there may be one first magnetic element 111 disposed in the front cavity or multiple first magnetic elements 111 disposed in the front cavity, and there may be one first magnetic element 111 disposed in the second sub-cavity 110a2 or multiple first magnetic elements 111 disposed in the second sub-cavity 110a2. In the embodiments of this application, no limitation is made.

[0062] Since the front cavity is the part of the speaker unit 113 that directly faces the external environment, and when the earphone 1 is placed in the mounting slot, the front cavity is also closer to the bottom of the mounting slot 2a. Therefore, by setting the first magnetic element 111 in the front cavity, the magnetic attraction effect with the second magnetic element 211 in the earphone case 2 can be enhanced, that is, the magnetic attraction stability of the sound-emitting part 110 in the earphone case 2 is enhanced.

[0063] Since the second sub-cavity 110a2 does not house the speaker unit 113, the second sub-cavity 110a2 has sufficient space to accommodate the first magnetic component 111.

[0064] In the embodiments of this application, a first magnetic element 111 is disposed in the front cavity and a second sub-cavity 110a2 for exemplary description.

[0065] Since the first magnetic component 111 is located inside the front cavity, that is, the first magnetic component 111 occupies the space of the speaker unit 113, by directly placing the first magnetic component 111 within the space of the speaker unit 113, the overall space of the earphone 1 can be significantly saved. This is especially important for the design of the earphone 1, which pursues a compact and lightweight design, making the earphone 1 more miniaturized, thus facilitating its portability and use.

[0066] The first magnetic component 111 located in the second sub-cavity 110a2 is also located on the side of the second sub-cavity 110a2, so there is enough space to install the spring and circuit board without affecting the layout of other electrical components inside the earphone 1, thus enabling the earphone 1 to have a compact layout and meet the requirements of miniaturization design.

[0067] Since the second cavity 120a is the cavity inside the battery compartment 120, and the battery 121 is installed inside this cavity to power the entire earphone 1, the battery 121 needs to occupy a large space inside the second cavity 120a. Therefore, please refer to... Figure 5 In this embodiment of the application, the second cavity 120a includes a first region 120a1 and a second region 120a2 arranged along the length of the battery compartment 120. The battery 121 is installed in the second region 120a2. A third magnetic element 122 is provided in the first region 120a1. The second region 120a2 is located closer to the ear hook 130 than the first region 120a1.

[0068] This allows the battery compartment 120 to have enough space to install electrical components such as power supplies, making the entire battery compartment 120 compact and facilitating the miniaturization design of the entire earphone 1.

[0069] On the other hand, by placing the third magnetic element 122 at the end of the battery compartment 120, the third magnetic element 122 can be placed closer to the fourth magnetic element 212 in the electrical cavity 210a, thereby enhancing the magnetic attraction and ensuring that the battery compartment 120 is stably attached to the earphone case 2.

[0070] For further information, please refer to [link / reference]. Figure 5Along the length of the battery compartment 120, the distance between the two sides of the first region 120a1 is h1, and the distance between the two sides of the second region 120a2 is h2, where 0.05 ≤ h1 / h2 ≤ 0.2. Here, h1 / h2 can be 0.05, 0.1, 0.15, or any value between 0.2 and above. By keeping the ratio of h1 / h2 within a suitable range, the internal space of the battery compartment 120 can be allocated more rationally. The smaller distance h1 in the first region 120a1 ensures sufficient space for the third magnetic component 122 without excessively occupying the overall space of the battery compartment 120. The larger distance h2 in the second region 120a2 provides sufficient installation space for the battery, ensuring its stability and safety.

[0071] Please see Figure 3 In one embodiment of this application, the third magnetic element 122 in the third cavity 130a is disposed at one end of the ear hook 130 connected to the sound-emitting part 110.

[0072] Since the sound-emitting part 110 is the audio output unit, its overall structure is relatively large. In order to increase the stability of the connection between the ear hook 130 and the sound-emitting part 110, there are many connection points between the ear hook 130 and the sound-emitting part 110. This results in a large space for the third cavity 130a near the sound-emitting part 110. In this way, there is enough space to place the third magnetic component 122, which not only facilitates the assembly of the earphone 1, but also makes it easy to place the third magnetic component 122 of different specifications according to the adsorption requirements.

[0073] In one embodiment, when the earphone is worn on the user's ear, the projection of the plurality of first magnetic elements 111 onto the first plane is a, and the projection of the sound-emitting part 110 onto the first plane is b, where a satisfies: 0.02b≤a≤0.05b, wherein the first plane is parallel to the user's sagittal plane.

[0074] It should be noted that in medicine, anatomy, and other fields, the human body can be defined by three basic planes: the sagittal plane, the coronal plane, and the horizontal plane, as well as three basic axes: the sagittal axis, the coronal axis, and the vertical axis. The sagittal plane is a section perpendicular to the ground along the anterior-posterior direction of the body, dividing the body into left and right parts. The coronal plane is a section perpendicular to the ground along the lateral direction of the body, dividing the body into anterior and posterior parts. The horizontal plane is a section parallel to the ground along the superior-inferior direction of the body, dividing the body into superior and inferior parts.

[0075] Where 'a' can be 0.02b, 0.03b, 0.04b, 0.05b, or any two of these values. Thus, by controlling the ratio of the projected area 'a' of the first magnetic component 111 on the first plane to the projected area 'b' of the sound-emitting part 110, sufficient magnetic force can be provided by the first magnetic component 111 to attract and secure the headphones, thereby enhancing wearing stability. Furthermore, a suitable ratio not only facilitates the installation of other electronic components within the first cavity 110a, but also achieves a balanced distribution of magnetic force while maintaining the overall weight of the headphones, reducing pressure on the user's ears and improving wearing comfort.

[0076] In another embodiment of this application, please refer to Figure 6 The sound-emitting part 110 has a first side 110b and a second side 110c that are opposite each other along its thickness direction. When the earphone is placed in the mounting groove 2a, the first side 110b faces the bottom of the mounting groove 2a, and the first magnetic member 111 is adjacent to the first side 110b.

[0077] The first magnetic component 111 is located at one end of the first cavity 110a near the bottom of the mounting groove 2a, forming a stronger magnetic attraction with the corresponding second magnetic component 211 inside the headphone case 2. This ensures that the headphone 1 can be quickly and stably attracted into the headphone case 2 when placed, preventing the headphone 1 from falling off or shifting due to external forces (such as vibration or shaking), thus reducing the probability of noise and impact.

[0078] On the other hand, by placing the first magnetic component 111 at one end of the first cavity 110a near the bottom of the mounting slot 2a, the first cavity 110a can have enough space to install the speaker unit 113 and other electrical components, thus optimizing the use of space and enabling the miniaturization and lightweight design of the sound-emitting part 110200.

[0079] Understandably, the second magnetic component 211 located in the electrical cavity 210a is also located at the end of the electrical cavity 210a facing the earphone 1. This allows it to form a stronger magnetic attraction with the first magnetic component 111 inside the earphone 1, thereby improving the stability of the earphone 1 placed in the mounting slot 2a. On the other hand, since the second magnetic component 211 is also located at the end of the electrical cavity 210a facing the earphone 1, there is sufficient space inside the electrical cavity 210a to house electrical components, such as the power supply, making the entire earphone case 2 compact.

[0080] Furthermore, see Figure 6Along the thickness direction of the sound-generating part 110, the distance between the first side 110b and the second side 110c is d, the distance between the first end 111a of the first magnetic element 111 and the first side 110b is d1, the distance between the second end 111b of the first magnetic element 111 and the second side 110c is d2, and the first end 111a and the second end 111b are arranged opposite to each other, wherein 0.05d≤d1≤0.2d, 0.6d≤d2≤0.9d.

[0081] That is, d1 can be between any two values ​​of 0.05d, 0.1d, 0.15d, 0.2d or above, and d2 can be between any two values ​​of 0.6d, 0.7d, 0.8d, 0.9d or above. By having d1 and d2 within the above ranges, the first cavity can have enough space to install other electronic devices, making the entire sound-generating part 110 compact and ensuring that the sound-generating part 110 has good adsorption capacity.

[0082] It should be understood that the first end 111a and the second end 111b of the first magnetic element 111 refer to the distance between the midpoint of the end face and the first side 110b and the second side 110c.

[0083] It is also important to understand that the sum of d1, d2, and the distance between the first end 111a and the second end 111b of the first magnetic element 111 is equal to d. Therefore, when d1 equals 0.2d, the value of d2 will not exceed 0.8d.

[0084] In one embodiment of this application, the housing 210 has an electrical cavity 210a, and a battery is disposed inside the electrical cavity 210a. When the earphone 1 is placed back into the charging case, the battery will charge the earphone 1. A charging interface is provided on the housing 210, which is electrically connected to the battery so that an external power source can supply power to the battery. A circuit board is also disposed inside the electrical cavity 210a, which integrates a battery management module responsible for controlling the charging and discharging process of the battery.

[0085] Considering the miniaturized and lightweight design of the earphone case 2, multiple second magnetic components 211 are arranged on the side of the electrical cavity 210a. In this way, there is enough space in the middle to install the circuit board and the battery. It is understood that a clearance can also be set on the circuit board to allow the second magnetic components 211 to extend out, thereby making the entire earphone case 2 compact and even more miniaturized.

[0086] Further, in the embodiments of this application, please refer to Figure 4 The electrical cavity 210a is provided with multiple positioning slots 211a, and multiple second magnetic components 211 are installed in the multiple positioning slots 211a one by one. The design of the positioning slots 211a can ensure that the second magnetic components 211 can be accurately placed in the predetermined position during installation.

[0087] The second magnetic component 211 can be installed in the positioning groove 211a by fitting or by gluing. Therefore, the positioning groove 211a provides additional support and fixation for the second magnetic component 211, making it less likely to loosen or fall off after installation and ensuring the stability of the magnetic attraction.

[0088] In this embodiment, both the first magnetic component 111 and the second magnetic component 211 are magnetic structures. The first magnetic component 111 can be installed in the earphone 1 by means of bracket fitting or adhesive bonding, etc. There are no restrictions. What needs to be ensured is that when the earphone 1 is placed in the mounting slot 2a, the first magnetic component 111 in the earphone 1 corresponds one-to-one with the second magnetic component 211 in the earphone case 2. In this way, the stability of the magnetism can be guaranteed, so that the earphone 1 is not easy to shake in the earphone case 2, thereby reducing the probability of noise and impact.
