[0048] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
[0049] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," "far," "near," "front," and "rear," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0050] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0051] The inventors discovered that when conventional clip-on open-back headphones are worn on the auricle, the angle between the back of the ear and the skull is small, which easily pushes the headphones towards the edge of the auricle, resulting in a longer distance between the sound outlet and the ear canal, thus causing sound leakage.
[0052] Based on this, this utility model embodiment provides an open-type magnetic ear clip earphone, see reference. Figures 1-3 As shown, it includes a functional compartment housing 100, a speaker compartment housing 200, a functional compartment magnet 6, a speaker compartment magnet 13, and a U-shaped connector 9;
[0053] The functional compartment magnet 6 is in close contact with the inner wall of the functional compartment housing 100 on the side near the speaker compartment housing 200;
[0054] The speaker housing magnet 13 is in close contact with the inner wall of the speaker housing 200 on the side near the speaker housing 200;
[0055] The U-shaped connector 9 includes a first straight section 901, an arc section 902, and a second straight section 903 that are integrally connected in sequence. The end of the first straight section 901 is connected to the functional compartment housing 100, and the end of the second straight section 903 is connected to the horn compartment housing 200.
[0056] The length of the second straight segment 903 is greater than the length of the first straight segment 901. The functional compartment magnet 6 is away from the first straight segment 901, and the horn compartment magnet 13 is close to the second straight segment 903, so that the functional compartment magnet 6 and the horn compartment magnet 13 can fit together completely.
[0057] In this embodiment, refer to Figure 2 As shown, the length of the second straight segment 903 is greater than the length of the first straight segment 901. Therefore, the functional compartment housing 100 is not directly opposite the speaker housing 200, but is partially misaligned. By arranging the functional compartment magnet 6 away from the first straight segment 901 and the speaker housing magnet 13 closer to the second straight segment 903, the two magnets can be positioned at the opposite parts of the functional compartment housing 100 and the speaker housing 200, allowing the functional compartment magnet 6 and the speaker housing magnet 13 to fit together completely. Even when the functional compartment magnet 6 and the speaker housing magnet 13 are fully fitted, the functional compartment housing 100 and the speaker housing 200 are still partially misaligned, thus better adapting to the shape of the earlobe where the space behind the ear is narrow and the ear clip space is wider.
[0058] Preferably, by setting the length of the first straight segment 901 and the length of the second straight segment 903, the offset distance between the functional housing 100 and the speaker housing 200 is controlled within the range of 4.2mm-4.5mm, which can better adapt to the auricle structure and allow the speaker housing 200 to be closer to the ear canal entrance.
[0059] The open-back magnetic clip-on earphones provided by this utility model have a first straight segment 901 connecting the functional housing 100, whose length is less than the second straight segment 903 connecting the speaker housing 200. When the functional housing magnet 6 and the speaker housing magnet 13 are fully engaged, the functional housing 100 and speaker housing 200 are partially misaligned. When wearing these earphones, the functional housing 100 fits snugly against the back of the ear, and the speaker housing 200 fits snugly against the concha. Due to the misaligned magnetic attraction between the functional housing 100 and speaker housing 200, they are better suited to the shape of the auricle, which has a narrower space behind the ear and a wider ear clip space. The functional housing 100 does not contact the skull, and the speaker housing 200 can be closer to the ear canal entrance, allowing the sound emitted by the earphone speaker to enter the ear canal more concentratedly, reducing sound leakage and improving sound transmission quality. Furthermore, the magnetic attraction increases the clamping force, reducing the risk of the earphones falling out and improving wearing stability.
[0060] In an optional implementation, refer to Figures 1-3As shown, the U-shaped connector 9 connects the functional compartment housing 1 and the speaker housing housing 16. Specifically, the functional compartment housing 1 is provided with a first insertion slot 1001, and the speaker housing housing 16 is provided with a second insertion slot 161. The two ends of the U-shaped connector 9 are respectively inserted into the first insertion slot 1001 and the second insertion slot 161. To improve connection stability, adhesive can be applied to the first insertion slot 1001 and the second insertion slot 161 to prevent the U-shaped connector 9 from separating from the functional compartment housing 1 and the speaker housing housing 16.
[0061] In this embodiment, refer to Figure 1 and Figure 2 As shown, the U-shaped connector 9 includes an outermost flexible shell 91 and an electrical connector and a shape memory elastic element 92 enclosed within the flexible shell 91. The flexible shell 91 connects the functional compartment shell 100 and the speaker compartment shell 200. The two ends of the electrical connector extend from the flexible shell 91 into the functional compartment shell 100 and the speaker compartment shell 200, respectively, for connecting the electronic components inside the two shells. The shape memory elastic element 92 is curved and has shape memory function, providing clamping force so that the functional compartment shell 100 and the speaker compartment shell 200 can be clamped onto the auricle.
[0062] In this embodiment, refer to Figures 1-3 As shown, the open-back magnetic ear clip earphone also includes a functional chamber airbag 8 and a speaker chamber airbag 10. The functional chamber airbag 8 is disposed outside the functional chamber housing 100, and the speaker chamber airbag 10 is disposed outside the speaker chamber housing 200. When the functional chamber housing 100 and the speaker chamber housing 200 are clamped to the auricle, the functional chamber magnet 6 and the speaker chamber magnet 13 are attracted to each other. The functional chamber airbag 8 is close to the back of the ear, and the speaker chamber airbag 10 is close to the concha cavity. The speaker chamber housing 200 is close to the entrance of the ear canal.
[0063] In this embodiment, refer to Figures 1-3 As shown, the functional compartment magnet 6 is fixed to the inner wall of the functional compartment housing 100 near the functional compartment airbag 8, and the speaker compartment magnet 13 is fixed to the inner wall of the speaker compartment housing 200 near the speaker compartment airbag 10. Between the functional compartment magnet 6 and the speaker compartment magnet 13, there is a layer of functional compartment housing 100, functional compartment airbag 8, speaker compartment airbag 10 and a layer of speaker compartment housing 200, which weakens the magnetic attraction to a certain extent, thereby ensuring that the clamping force is not too large. Combined with the buffering effect of the two airbags, it can effectively prevent ear discomfort.
[0064] In this embodiment, the speaker housing 200 is used to accommodate components such as speakers, as shown in the reference. Figures 1-3As shown, the device includes a speaker housing outer shell 16 and a speaker housing inner shell 11 that are fastened together. The speaker housing airbag 10 is open, enclosing the speaker housing inner shell 11 and sealing it to maintain its inflated state. The speaker housing magnet 13 is fixed to the inner wall of the speaker housing inner shell 11 on the side near the speaker housing airbag 10.
[0065] In this embodiment, refer to Figures 1-3 As shown, a sound outlet mesh 20 is provided on the side of the speaker housing 16 away from the second straight section 903. The sound outlet mesh 20 is inclined at 92°-110° towards the side of the speaker housing 16 away from the speaker housing airbag 10, with the opening surface of the speaker housing 10 as the reference. This better adapts to the shape of the concha cavity, so that when the speaker housing 200 is located in the concha cavity, the sound outlet mesh 20 can be directly facing the ear canal entrance, allowing the sound to be concentrated and transmitted into the ear canal, reducing sound leakage and improving the sound transmission effect. Furthermore, a sound outlet mesh fabric 19 is provided on the inner side of the sound outlet mesh 20 to absorb or reflect some sound waves to improve the sound quality and timbre, while also serving a dustproof function.
[0066] In one specific embodiment, reference is made to Figure 2 As shown, the mouthpiece steel mesh 20 is tilted at 94° to the side of the speaker housing 16 away from the speaker housing airbag 10 with the opening surface of the speaker housing airbag 10 as the reference, so that when the speaker housing 200 is located in the concha cavity, the mouthpiece steel mesh 20 can be directly facing the ear canal entrance.
[0067] In this embodiment, the functional compartment housing 100 is used to accommodate components such as the PCBA board 4, as shown in the reference. Figures 1-3 As shown, the device includes a functional compartment outer shell 1 and a functional compartment inner shell 7 that are fastened together. The functional compartment airbag 8 is an open airbag, and the functional compartment inner shell 7 is at least partially located inside the functional compartment airbag 8, so that the functional compartment airbag 8 at least partially encloses the functional compartment inner shell 7. Furthermore, the inner wall of the open end of the functional compartment airbag 8 is sealed to the outer wall of the functional compartment inner shell 7, thereby achieving a seal for the functional compartment airbag 8 and ensuring that the functional compartment airbag 8 can maintain its inflated state. The functional compartment magnet 6 is fixed to the inner wall of the functional compartment inner shell 7 on the side near the functional compartment airbag 8.
[0068] In an optional implementation, refer to Figures 1-3As shown, the sealing connection between the functional chamber airbag 8 and the functional chamber inner shell 7 can be achieved by: a second sealing groove 71 being provided on the outer wall of the functional chamber inner shell 7, and a raised second sealing ring (not shown in the figure) being provided on the inner wall of the functional chamber airbag 8. When the functional chamber airbag 8 encloses the functional chamber inner shell 7, the second sealing ring is engaged in the second sealing groove 71, thereby achieving a seal for the functional chamber airbag 8. Furthermore, the inner edge of the opening end of the functional chamber airbag 8 is tightly bonded to the outer wall of the functional chamber inner shell 7, which not only ensures the aesthetics of the earphone but also achieves a secondary seal for the functional chamber airbag 8, effectively preventing air leakage and improving durability.
[0069] In an optional implementation, refer to Figures 1-3 As shown, the speaker chamber airbag 10 and the speaker chamber inner shell 11 are sealed together by the following method: the outer wall of the speaker chamber inner shell 11 is provided with a first sealing groove 111, and the inner wall of the speaker chamber airbag 10 is provided with a raised first sealing ring (not shown in the figure). When the speaker chamber airbag 10 covers the speaker chamber inner shell 11, the first sealing ring is engaged in the first sealing groove 111, thereby achieving a seal on the speaker chamber airbag 10. Furthermore, the inner edge of the opening end of the speaker chamber airbag 10 is tightly bonded to the outer wall of the speaker chamber inner shell 11, which not only ensures the aesthetics of the earphone but also achieves a secondary seal on the speaker chamber airbag 10, effectively preventing air leakage and improving durability.
[0070] This utility model provides open-back magnetic clip-on earphones. By incorporating a functional compartment magnet 6 and a speaker compartment magnet 13, the magnetic attraction increases the clamping force of the open-back magnetic clip-on earphones, reducing the risk of the earphones falling out and improving wearing stability. Airbags are respectively placed in the functional compartment housing 100 and the speaker compartment housing 200, reducing pressure on the wearer's ear and preventing pressure concentration. Since the two airbags are located between the two magnets, the cooperation between the magnets and the airbags achieves an effective balance between wearing stability and wearing comfort, ensuring sufficient wearing comfort while maintaining stability, effectively improving the user experience. Furthermore, using airbags as cushioning components solves the problem of ear pain caused by prolonged wear of ear-clip earphones with conventional cushioning materials, and also solves the problem of hardening of conventional cushioning materials after long-term use, making it highly valuable for widespread application.
[0071] In an optional implementation, refer to Figures 1-3 As shown, the open-back magnetic ear clip headphones also include a PCBA board 4 and a speaker 14. The PCBA board 4 is located inside the functional compartment housing 100, and the speaker 14 is located inside the speaker compartment housing 200. The sound outlet of the speaker 14 faces the sound outlet steel mesh 20. Electrical connectors are connected to the PCBA board 4 and the speaker 14 respectively, so that the signal can be transmitted to the speaker. The speaker 14 converts the electrical signal into sound and outputs it.
[0072] In an optional implementation, refer to Figures 1-3 As shown, tuning holes 112 are symmetrically arranged on both sides of the speaker cavity inner shell 11, and the speaker cavity airbag 10 is correspondingly provided with through holes 101, with the through holes 101 of the speaker cavity airbag 10 being sealed and bonded to the speaker cavity inner shell 11. The speaker cavity magnet 13 is located between the two tuning holes 112 and is provided with a clearance notch corresponding to the shape of the tuning holes 112, thereby ensuring that the speaker cavity magnet 13 can fit tightly against the inner wall of the speaker cavity inner shell 11. When the speaker vibrates and drives the air flow, it will cause the air pressure inside the speaker cavity shell 200 to increase, increasing the resistance of the diaphragm vibration, making the headphone sound muffled and not clear enough. The tuning holes 112 allow the air to flow freely, which can prevent pressure buildup and make the sound quality clearer and more transparent. Furthermore, a tuning mesh 12 can be attached to the inside of the tuning holes 112. The tuning mesh 12 can absorb or reflect some sound waves to improve the sound quality and timbre, and at the same time, it can also play a role in dust prevention.
[0073] In an optional implementation, refer to Figures 1-3 As shown, the open-back magnetic earbuds also include a battery 5 and a charging copper post 18. The battery 5 and the charging copper post 18 are disposed within the functional compartment housing 100 and are electrically connected to the PCBA board 4. The battery 5 supplies power to other electronic components through the circuitry on the PCBA board 4. After the charging copper post 18 is connected to a charging device such as the earbud charging case, it can transfer power to the battery 5 through the circuitry on the PCBA board 4. The functional compartment housing 100 is provided with a charging post receiving hole, and the end of the charging copper post 18 is located within the charging post receiving hole, allowing it to contact the charging device such as the earbud charging case.
[0074] In an optional implementation, a noise-canceling microphone module (not shown in the figure) is integrated on the PCBA board 4 to improve voice clarity and suppress background noise. Furthermore, the functional compartment housing 1 is provided with a microphone hole communicating with the noise-canceling microphone module, and a microphone mesh 3 is provided inside the first microphone hole to prevent dust from entering the functional compartment housing 100.
[0075] In an optional implementation, refer to Figure 3 As shown, the open-back magnetic earcup headphones also include a touch FPC2. The touch FPC2 is housed in the function compartment housing 100 and is tightly attached to the inner wall of the function compartment housing 1. It is electrically connected to the PCBA board 4 by means of soldering or crimping. When the corresponding position of the function compartment housing 1 is touched, the circuit of the touch FPC2 is triggered and transmitted to the corresponding circuit point on the PCBA board 4. After the circuit system on the PCBA board 4 detects this change, it will perform the corresponding operation, such as playing / pausing music, answering / hanging up a call, etc.
[0076] In an optional implementation, refer to Figure 3As shown, the open-back magnetic earcup headset also includes a microphone (not shown) and a call FPC15. The call FPC15 connects the microphone and the electrical connector, thereby connecting the microphone to the PCBA board 4 for signal transmission.
[0077] In an optional implementation, refer to Figure 3 As shown, the open-back magnetic earbuds also include an earbud magnet 17, which is used to magnetically engage with the magnet inside the charging case for precise positioning and placement. The earbud magnet 17 is located inside the functional compartment housing 100 on the side away from the flexible housing 91 and is in close contact with the inner wall of the functional compartment housing 1, facilitating magnetic attachment to the charging case.
[0078] In an optional implementation, the inflation volume of the functional compartment airbag 8 is 90%-95% of its internal volume, and the inflation volume of the speaker compartment airbag 10 is 90%-95% of its internal volume. This avoids insufficient inflation leading to cushioning failure, while allowing sufficient compression. Furthermore, both the functional compartment airbag 8 and the speaker compartment airbag 10 are made of elastomers with a hardness of 30HA-60HA, thereby controlling the compression distance between the two airbags to approximately 1.5mm. This ensures a large contact area between the airbags and the auricle under compression, preventing pressure concentration and achieving an effective balance between wearing stability and wearing comfort. Under the premise of ensuring wearing stability, sufficient wearing comfort is guaranteed, effectively improving the user experience.
[0079] In one specific embodiment, the memory elastic element 92 can be made of nickel-titanium memory steel wire, which has good elasticity and thermal stability, ensuring that the memory elastic element 92 can provide sufficient elastic force.
