[0049] 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.

[0050] 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.

[0051] 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.

[0052] The inventors discovered that existing open-back clip-on headphones have a problem in balancing clamping force and wearing comfort. Although flexible materials such as silicone or memory foam can be used to cushion the clipping part, the softness of silicone or memory foam will decrease under compression if worn for a long time at one time, thus reducing wearing comfort. Furthermore, silicone and memory foam and similar materials will undergo certain plastic deformation after long-term use, eventually causing the materials to harden and lose their cushioning effect.

[0053] Based on this, this utility model embodiment provides an ear clip-on open-back headphone with an airbag, see reference. Figure 1 and Figure 2 As shown, it includes a functional compartment housing 100, a functional compartment airbag 8, a horn compartment housing 200, a horn compartment airbag 10, and an arc-shaped connector 9;

[0054] The arc-shaped connector 9 connects the functional housing 100 and the speaker housing 200 respectively, and the functional housing 100 and the speaker housing 200 can be clamped in the auricle under the elastic force of the arc-shaped connector 9.

[0055] 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 in the auricle, 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.

[0056] The inflation volume of the functional compartment airbag 8 is 90% to 95% of its internal volume.

[0057] The inflation volume of the horn compartment airbag 10 is 90% to 95% of the internal volume of the horn compartment airbag 10;

[0058] The functional compartment airbag 8 and the horn compartment airbag 10 are made of elastic material with a hardness of 30HA-60HA.

[0059] In this embodiment, refer to Figure 1 and Figure 2 As shown, the arc-shaped connector 9 connects the functional housing 100 and the speaker housing 200 respectively, so that the earphone is in the shape of an ear clip. Both the functional housing 100 and the speaker housing 200 are equipped with airbags for cushioning. When worn, the arc-shaped connector 9 provides clamping force, and the auricle is clamped between the functional housing 100 and the speaker housing 200. Furthermore, the functional housing 100 is located behind the ear, and the functional housing airbag 8 is close to the back of the ear. The speaker housing 200 is located in the concha cavity, and the speaker housing airbag 10 is close to the concha cavity, thereby reducing the pressure on the auricle. Moreover, the airbag will not gradually harden with the increase of wearing time, ensuring comfort for long-term wear.

[0060] In this embodiment, the inflation volume of the functional compartment airbag 8 is designed to be 90% to 95% of its internal volume, and the inflation volume of the speaker compartment airbag 10 is designed to be 90% to 95% of its internal volume. This avoids insufficient inflation volume leading to cushioning failure, while allowing sufficient compression. Combined with an elastic material with a hardness of 30HA-60HA, the compression distance between the two airbags is controlled at about 1.5mm. This ensures that the airbags have a large contact surface with the auricle under compression, avoiding 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.

[0061] The ear clip-on open-back headphones with airbags provided by this utility model reduce the pressure on the wearer's auricle by setting airbags on the inner sides of the functional housing 100 and the speaker housing 200, solving the problem of ear pain caused by wearing ear clip-on headphones with conventional cushioning materials for a long time, and solving the problem of hardening of conventional cushioning materials after long-term use. While improving wearing comfort, it is also conducive to improving economic efficiency and has high promotion and application value.

[0062] In an optional embodiment, the functional compartment housing 100 is used to accommodate components such as the PCBA board 4, as shown in the reference. Figure 1 and Figure 2As 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 covers 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 on the functional compartment airbag 8 and ensuring that the functional compartment airbag 8 can maintain its inflated state.

[0063] In an optional embodiment, the speaker housing 200 is used to accommodate components such as the speaker 14, see reference. Figure 1 and Figure 2 As shown, the device includes a speaker compartment outer shell 16 and a speaker compartment inner shell 11 that are fastened together. The speaker compartment airbag 10 is also an open airbag. The speaker compartment inner shell 11 is at least partially located inside the speaker compartment airbag 10, so that the speaker compartment airbag 10 at least partially covers the speaker compartment inner shell 11. Furthermore, the inner wall of the open end of the speaker compartment airbag 10 is sealed to the outer wall of the speaker compartment inner shell 11, thereby achieving a seal on the speaker compartment airbag 10 and ensuring that the speaker compartment airbag 10 can maintain its inflated state.

[0064] In an optional implementation, refer to Figure 1 and Figure 2 As shown, the sealing connection between the functional chamber airbag 8 and the functional chamber inner shell 7 can be achieved by: a first sealing groove 71 being provided on the outer wall of the functional chamber inner shell 7, and a raised first 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 first sealing ring is engaged in the first 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.

[0065] In an optional implementation, refer to Figure 1 and Figure 2 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 second sealing groove 111, and the inner wall of the speaker chamber airbag 10 is provided with a raised second sealing ring (not shown in the figure). When the speaker chamber airbag 10 covers the speaker chamber inner shell 11, the second sealing ring is engaged in the second 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.

[0066] In an optional implementation, refer to Figure 1 and Figure 2 As shown, the arc-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 arc-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 arc-shaped connector 9 from separating from the functional compartment housing 1 and the speaker housing housing 16.

[0067] In an optional embodiment, the arc-shaped connector 9 includes a flexible shell 91, a shape memory element (not shown), and an electrical connector (not shown). The flexible shell 91 is fitted onto the shape memory element and the electrical connector. The flexible shell 91 connects the functional housing 100 and the speaker housing 200, respectively. The shape memory element is curved and has shape memory function to provide clamping force. The shape memory element undergoes elastic deformation under external force, giving the arc-shaped connector 9 an elastic clamping force, which can stably clamp the ear when the earphone is worn. Furthermore, the inclusion of the functional housing airbag 8 and the speaker housing airbag 10 improves comfort, preventing pain even during prolonged wear. The two ends of the electrical connector extend from the flexible shell 91 into the functional housing 100 and the speaker housing 200, respectively, for connecting electronic components within the two housings.

[0068] In one specific embodiment, the memory elastic element can be made of nickel-titanium memory steel wire, which has good elasticity and thermal stability, ensuring that the memory elastic element can provide sufficient elastic force.

[0069] In an optional implementation, refer to Figure 2 As shown, the ear-clip open-back headphones with airbags also include a PCBA board 4 and a speaker 14. The PCBA board 4 is disposed inside the functional compartment housing 100, and the speaker 14 is disposed inside the speaker compartment housing 200. Electrical connectors are respectively connected to the PCBA board 4 and the speaker 14, thereby enabling signal transmission to the speaker 14, which converts the electrical signal into sound and outputs it.

[0070] In an optional implementation, refer to Figure 2 As shown, the speaker housing 200 is provided with a sound outlet mesh 20. Specifically, the speaker housing 16 is provided with a sound outlet mesh 20. When the headphones are worn, the speaker housing airbag 10 fits tightly against the concha cavity, and the sound outlet mesh 20 faces the ear canal, with a certain distance between it and the ear canal entrance to avoid completely blocking the ear canal. The sound outlet of the speaker 14 is aligned with the sound outlet mesh 20, allowing sound to naturally enter the ear canal. Furthermore, the inner side of the sound outlet mesh 20 is provided with a sound outlet mesh fabric 19, which is used to absorb or reflect some sound waves to improve the sound quality and timbre, while also serving a dustproof function.

[0071] In an optional implementation, refer to Figure 2 As shown, tuning holes 112 are respectively provided on both sides of the speaker cavity inner shell 11, and the speaker cavity airbag 10 is provided with a corresponding through hole 101, and the through hole 101 of the speaker cavity airbag 10 is sealed and bonded to the speaker cavity inner shell 11. When the speaker 14 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.

[0072] In an optional implementation, refer to Figure 2 As shown, the ear-clip open-back earphone with airbag also includes 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 earphone 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 earphone charging case.

[0073] In an optional implementation, a noise-canceling microphone module (not shown) is integrated on the PCBA board 4 to improve speech clarity and suppress background noise. Furthermore, the functional compartment housing 1 is provided with a microphone hole (not shown) communicating with the noise-canceling microphone module, and a microphone mesh 3 is provided inside the microphone hole to prevent dust from entering the functional compartment housing 100.

[0074] In an optional implementation, refer to Figure 2 As shown, the air-cushioned open-back earbuds also include a touch FPC2. The touch FPC2 is housed in the functional housing 100 and is tightly attached to the inner wall of the functional housing 1, and is electrically connected to the PCBA board 4 by means of soldering or crimping. When the corresponding position of the functional 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.

[0075] In an optional implementation, refer to Figure 2As shown, the air-cushioned open-back earbuds also include 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.

[0076] In an optional implementation, refer to Figure 2 As shown, the airbag-equipped earbuds also include a first magnet 17, which is used to magnetically engage with the magnet inside the charging case to achieve precise positioning and placement. The first 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 of the charging case.

[0077] In an optional implementation, refer to Figure 2 As shown, the air-cushioned open-back earphone also includes a second magnet 6 and a third magnet 13. The second magnet 6 is disposed within the functional housing 100, and the third housing is disposed within the speaker housing 200, to increase the clamping force. Specifically, both the second magnet 6 and the third magnet 13 are disc-shaped. The second magnet 6 is in close contact with the side of the functional housing 7 near the speaker housing 200, and the third magnet 13 is in close contact with the side of the speaker housing 11 near the functional housing 100. When the earphone is clamped to the ear, it not only has the clamping force provided by the memory elastic element, but also the clamping force generated by the magnetic attraction between the second magnet 6 and the third magnet 13, thereby increasing the clamping force and improving wearing stability. Combined with the cushioning effect of the functional housing airbag 8 and the speaker housing airbag 10, it also ensures sufficient wearing comfort, making it highly valuable for widespread application.

[0078] In an optional implementation, refer to Figure 1 and Figure 2 As shown, the arc-shaped connector 9 has an arc-shaped section in the middle and straight sections at both ends. The straight section connecting the speaker housing 200 can be slightly longer than the straight section connecting the functional housing 100, so that the functional housing 100 and the speaker housing 200 are partially offset. When the headphones are worn, they can better adapt to the shape of the auricle with a narrower space behind the ear and a wider space in the ear clip cavity. The functional housing 100 does not contact the skull, and the speaker housing 200 can be closer to the entrance of the ear canal, so that the sound emitted by the headphone speaker can enter the ear canal more concentratedly, reducing sound leakage and improving the sound transmission quality.

[0079] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. This disclosure is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this disclosure is limited only by the appended claims. Thus, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model is also intended to include these modifications and variations.
