Description

Technical Field

[0001] This application relates to, but is not limited to, the field of headphone technology, and in particular to a headphone and headphone module for improving sound quality. Background Technology

[0002] In today's society, headphones have become an indispensable electronic product in people's daily lives.

[0003] In related technologies, the tuning hole of the earphone front cavity is located in the in-ear area. When some earphones are worn, the tuning hole will come into contact with the user's skin, causing the tuning hole to be blocked by the skin. This obstructs the release of pressure in the front cavity, producing abnormal noise and affecting the sound quality and user experience. Utility Model Content

[0004] The headphones with improved sound quality provided in this application can optimize the air pressure release path, reduce the impact of skin on the pressure release inside the headphones and the ear canal, reduce abnormal noise, and optimize sound quality.

[0005] On one hand, this application provides an earphone with improved sound quality, which includes an earphone shell and a speaker; the earphone shell has a receiving cavity, which includes a front earphone cavity and a rear earphone cavity; the speaker is installed in the receiving cavity, and the speaker includes a diaphragm and a base, with the diaphragm installed on the base, the front earphone cavity including a side of the diaphragm facing away from the base, and the rear earphone cavity including a side of the base facing away from the diaphragm; the earphone shell is provided with a sound outlet and a tuning hole, which are used to communicate with the outside world and the front earphone cavity; in the wearing state, the sound outlet corresponds to the user's ear canal, and there is a gap between the tuning hole and the user's skin.

[0006] The improved sound quality headphones provided in this application have a speaker enclosure divided into a front cavity and a rear cavity. The sound outlet is positioned corresponding to the front cavity, connecting the front cavity and the ear canal when the headphones are worn. Since the tuning hole connects the front cavity to the outside, this structure allows both the ear canal and the front cavity to communicate with the outside, thus releasing pressure within the ear canal and the front cavity. Because there is a gap between the tuning hole and the user's skin when worn, the tuning channel is not affected by the skin around the ear. The connection between the front cavity, ear canal, and outside via the tuning hole releases pressure within the ear canal and the enclosure. Furthermore, the gap between the tuning hole and the user's skin prevents sweat, dander, and other substances from clogging the tuning hole, reducing the likelihood of blockage. Compared to related technologies, this improves upon situations where skin blockage of the tuning hole hinders pressure release, reducing the impact of abnormal noise on sound quality and user experience. Therefore, the headphones provided in this application embodiment can optimize the air pressure release path, reduce the impact of skin on the pressure release inside the headphones and the ear canal, reduce abnormal noise, and optimize sound quality.

[0007] In one possible implementation of this application, the earphone shell is further provided with a pressure relief hole, which is used to connect the outside world and the rear cavity of the earphone; when worn, there is a gap between the pressure relief hole and the user's skin.

[0008] In one possible implementation of this application, the earphone shell is composed of a front half shell and a rear half shell, which together form a receiving cavity; the sound outlet is disposed in the front half shell; and the tuning hole is disposed in the rear half shell.

[0009] In one possible implementation of this application, the headphones with improved sound quality further include a mounting structure disposed within a receiving cavity, the mounting structure being used to mount a speaker; the mounting structure has a tuning channel that connects the front cavity and the rear cavity of the headphones; and a tuning hole that connects the outside world and the rear cavity of the headphones.

[0010] In one possible implementation of this application, the headphones that improve sound quality further include a pressure relief component, which is disposed in the tuning channel. The pressure relief component includes a pressure relief channel, the two ends of which are respectively connected to the front cavity of the headphones and the rear cavity of the headphones.

[0011] In one possible implementation of this application, the pressure relief channel includes a first opening and a second opening, the first opening being disposed toward the front cavity of the earphone and the second opening being disposed toward the rear cavity of the earphone, and there is an included angle between the axis of the first opening and the axis of the second opening.

[0012] In one possible implementation of this application, the mounting structure includes a first limiting surface that is in contact with the circumferential surface of the speaker, a tuning channel that passes through the first limiting surface radially along the speaker, and a pressure relief component whose surface facing the speaker is in contact with the circumferential surface of the speaker.

[0013] In one possible implementation of this application, the earphone housing has a receiving groove that communicates with the tuning channel. The receiving groove extends in a direction away from the rear cavity of the earphone. One end of the pressure relief member is disposed in the receiving groove, and the other end of the pressure relief member extends into the tuning channel.

[0014] In one possible implementation of this application, the headphones for improving sound quality further include a first tuning mesh disposed in the second opening of the pressure relief member.

[0015] On the other hand, this application provides an earphone module, which includes an earphone case and earphones with improved sound quality as described above, wherein the earphones with improved sound quality are housed inside the earphone case.

[0016] The headphone module provided in this application, since it includes any of the above-mentioned headphone features that improve sound quality, has the same technical effect, namely, it can optimize the air pressure release path, reduce the influence of skin on the pressure release inside the headphone and the ear canal, reduce abnormal noise, and optimize sound quality.

Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0031] In today's society, headphones have become an indispensable electronic product in people's daily lives. When wearing headphones, due to individual differences in the concha of the ear, the tuning hole used to balance the internal pressure of the headphones may come into contact with the auricle or inner ear skin, causing the skin to block the tuning hole. In related technologies, the tuning hole in the front cavity of the headphone is located in the in-ear area. When some users wear headphones, the tuning hole comes into contact with their skin, causing it to be blocked. This obstructs the release of pressure within the front cavity, producing abnormal noise and affecting sound quality and the user experience.

[0032] The sound-quality-improving headphones provided in this application embodiment may include open-back headphones, closed-back headphones, ear-hook headphones, clip-on headphones, in-ear headphones, wireless headphones, or wired headphones, etc. This application embodiment does not impose any limitations on this. In one possible implementation provided in this application embodiment, the sound-quality-improving headphones are semi-in-ear headphones.

[0033] This application provides an embodiment of headphones with improved sound quality, referring to... Figure 1 , Figure 2 and Figure 3 The improved sound quality headphones include an earphone shell 1 and a speaker 6; the earphone shell 1 has a receiving cavity 11, which includes a front earphone cavity 111 and a rear earphone cavity 112; the speaker 6 is mounted in the receiving cavity 11, and the speaker 6 includes a diaphragm and a base, with the diaphragm mounted on the base, the front earphone cavity 111 including a side of the diaphragm facing away from the base, and the rear earphone cavity 112 including a side of the base facing away from the diaphragm; the earphone shell 1 is provided with a sound outlet 12 and a tuning hole 13, which are used to connect the outside world and the front earphone cavity 111; in the wearing state, the sound outlet 12 corresponds to the user's ear canal, and there is a gap between the tuning hole 13 and the user's skin.

[0034] In this embodiment, the earphone shell 1 constitutes the main structure of the earphone. The earphone shell 1 can be made of plastic, metal or composite material, thereby taking into account both lightweight and strength.

[0035] In this embodiment, the receiving cavity 11 is a cavity formed inside the earphone shell 1, used to accommodate components such as the speaker 6 and the battery assembly.

[0036] In this embodiment, the loudspeaker 6 includes a diaphragm and a base. The diaphragm is a thin film component that can vibrate to produce sound and can be used to generate sound waves. The base is a fixed structure for supporting the diaphragm and typically includes driving components such as a magnetic circuit and a voice coil.

[0037] In this embodiment, the headphone front cavity 111 can be understood as being located on the side of the diaphragm away from the base (i.e., the side of the diaphragm facing the user's ear canal). The headphone front cavity 111 includes a space from the side of the diaphragm facing the user's ear canal to the sound outlet 12. Sound waves are transmitted into the ear canal through the headphone front cavity 111 and the sound outlet 12. The headphone rear cavity 112 is located on the side of the base away from the diaphragm (i.e., the space behind the diaphragm), which can also be understood as the space from the side of the base away from the diaphragm to the space away from the ear canal.

[0038] In this embodiment of the application, the sound outlet 12 is used for the headphone to emit sound. The correspondence between the sound outlet and the user's ear canal means that when wearing headphones, the sound outlet 12 is aligned with the ear canal, or the sound outlet 12 is located inside the ear canal.

[0039] In this embodiment, the tuning hole 13 connects the earphone front cavity 111 to the outside world and can adjust the acoustic characteristics inside the earphone. When worn, there is a gap between the tuning hole 13 and the user's skin, meaning the tuning hole 13 is not completely blocked by the ear skin or auricle, allowing for some airflow. When worn, the tuning hole 13 can be located outside the auricle (ear canal skin), thereby reducing contact between the tuning hole 13 and the skin; alternatively, when worn, the tuning hole 13 can be isolated from the skin by other structures, such as protrusions or airflow channels around the tuning hole 13, allowing it to communicate with the outside world.

[0040] In one embodiment of this application, the size of the tuning hole 13 is smaller than the size of the sound outlet 12. The size of the tuning hole 13 can be adjusted according to the headphone parameters. With a smaller size, even if the tuning hole 13 slightly contacts the skin when worn, it will not be completely blocked, and the tuning hole 13 can still maintain a certain amount of airflow exchange. At the same time, the smaller size of the tuning hole 13 can reduce the entry of larger dust, earwax, or hair, reducing the probability of blockage.

[0041] In one embodiment of this application, the front cavity 111 and the rear cavity 112 of the earphone may be connected, or they may not be connected; this application does not limit this.

[0042] In this embodiment of the improved sound quality headphones, the speaker 6 divides the receiving cavity 11 into a front cavity 111 and a rear cavity 112. The sound outlet 12 is provided corresponding to the front cavity 111. When the headphones are worn, the sound outlet 12 connects the front cavity 111 and the space inside the ear canal. Since the tuning hole 13 connects the front cavity 111 to the outside, in this structure, both the space inside the ear canal and the front cavity 111 are connected to the outside through the tuning hole 13, thereby releasing the pressure inside the ear canal and the front cavity 111. Since there is a gap between the tuning hole 13 and the user's skin when wearing the headphones, the tuning channel 21 is not affected by the skin around the ear. When the headphones are worn, the front cavity 111, the inside of the ear canal and the outside are connected through the tuning hole 13, which can release the pressure inside the ear canal and the receiving cavity 11. At the same time, the gap between the tuning hole 13 and the user's skin can prevent sweat, dander and other substances from clogging the tuning hole 13, reducing the possibility of the tuning hole 13 being blocked. Compared to related technologies, this invention improves upon the situation where skin blocking the tuning hole 13 obstructs pressure release, thereby reducing the impact of abnormal noise on sound quality and user experience. Therefore, the headphones provided in this embodiment optimize the air pressure release path, reduce the influence of skin on the pressure release inside the headphones and ear canal, reduce abnormal noise, and optimize sound quality.

[0043] In some possible embodiments of this application, the earphone housing 1 is also provided with a pressure relief hole, which is used to connect the outside world and the earphone rear cavity 112; when worn, there is a gap between the pressure relief hole and the user's skin.

[0044] In this embodiment, when the front cavity 111 and the rear cavity 112 of the earphone are not connected, the tuning hole 13 is used to connect the front cavity 111 of the earphone to the outside world to balance the air pressure between the front cavity 111 of the earphone and the outside world; the pressure relief hole is used to connect the rear cavity 112 of the earphone to the outside world, forming an airflow channel between the rear cavity 112 of the earphone and the outside world to balance the air pressure between the rear cavity 112 of the earphone and the outside world.

[0045] Since the front cavity 111 (sound output end) and the rear cavity 112 (back side of diaphragm) of the earphone are physically isolated (e.g., separated by the speaker 6 base), the pressure relief hole only acts on the rear cavity 112 of the earphone, which can reduce the tuning effect on the acoustics of the front cavity.

[0046] In this embodiment, the pressure relief hole is located on the shell wall of the earphone shell 1 in the area corresponding to the rear cavity 112 of the earphone. The size of the pressure relief hole can be adjusted according to the parameters of the earphone. By adjusting the size of the pressure relief hole, the low frequency leakage can be adjusted to reduce the situation of excessively strong (booming) or insufficient (thin) bass.

[0047] In this embodiment, when worn, there is a gap between the pressure relief hole and the user's skin. The pressure relief hole can be set on the side or top of the earphone housing 1, avoiding the area where the auricle is located, thereby reducing the risk of the skin around the auricle blocking the pressure relief hole.

[0048] It should be explained that the side of the earphone shell 1 refers to the side adjacent to or opposite to the ear canal when the earphone is being worn; the top of the earphone shell 1 refers to the surface of the earphone shell 1 visible from above the user's head when the earphone is being worn.

[0049] In some possible embodiments of this application, reference is made to Figure 1 and Figure 2 The earphone housing 1 is composed of a front half-shell 15 and a rear half-shell 16, which together form a receiving cavity 11; the sound outlet 12 is located in the front half-shell 15; and the tuning hole 13 is located in the rear half-shell 16.

[0050] In this embodiment, the front half-shell 15 and the rear half-shell 16 combine to form a receiving cavity 11. In one example, the earphone front cavity 111 can be formed by the front half-shell 15 and the speaker 6, and the earphone rear cavity 112 can be formed by the rear half-shell 16 and the speaker 6; in another example, the earphone front cavity 111 can be formed by the front half-shell 15, a portion of the rear half-shell 16 adjacent to the front half-shell 15, and the speaker 6, wherein a portion of the rear half-shell 16 participates in the formation of the earphone front cavity 111, and another portion of the rear half-shell 16 and the speaker 6 enclose to form the earphone rear cavity 112; in yet another example, the earphone front cavity 111 can be formed by a portion of the front half-shell 15 and the speaker 6, and the other portion of the front half-shell 15, the rear half-shell 16, and the speaker 6 enclose to form the earphone rear cavity 112.

[0051] In this embodiment of the application, when the front cavity 111 and the rear cavity 112 of the earphone are connected, the tuning hole 13 is disposed in the rear half shell 16. The rear half shell 16 can refer to the part used to enclose and form the rear cavity 112 of the earphone, or it can refer to the part used to enclose and form the front cavity 111 of the earphone. The tuning hole 13 can connect the outside world, the rear cavity 112 of the earphone and the front cavity 111 of the earphone, or it can connect the outside world and the front cavity 111 of the earphone.

[0052] In this embodiment of the application, when the front cavity 111 and the rear cavity 112 of the earphone are not connected, the tuning hole 13 is provided in the rear half shell 16, which refers to the part that is provided near the front half shell 15 and is used to form the front cavity 111 of the earphone. The tuning hole 13 connects the outside world with the front cavity 111 of the earphone.

[0053] In this embodiment, the sound outlet 12 is located on the front half shell 15. When the headphones are worn, the sound outlet 12 is aligned with the ear canal. The outer wall of the front half shell 15 is likely to come into contact with the ear canal or the skin around the ear. Since the tuning hole 13 is located on the rear half shell 16, there is a gap between the tuning hole 13 and the front half shell 15. When wearing headphones, the contact between the tuning hole 13 and the skin around the ear can be reduced, thereby reducing the possibility of the tuning hole 13 being blocked.

[0054] In another embodiment, the earphone housing 1 is composed of a front half-shell 15 and a rear half-shell 16, which together form a receiving cavity 11; the sound outlet 12 and the tuning hole 13 are both disposed on the front half-shell 15.

[0055] In this embodiment, both the sound outlet 12 and the tuning hole 13 are located on the front half of the shell 15. The tuning hole 13 and the sound outlet 12 can be arranged non-coplanarly in three-dimensional space. For example, there is an offset between the circumferential direction of the tuning hole 13 and the circumferential direction of the sound outlet 12; there is a depth difference between the tuning hole 13 and the sound outlet 12. Alternatively, a three-dimensional staggered layout can be used to position the tuning hole 13 in the non-contact area of ​​the auricle. This allows for a gap between the tuning hole 13 and the user's skin during wearing, reducing the possibility of the tuning hole 13 being blocked by the skin, reducing abnormal noise, and optimizing sound quality.

[0056] In some possible embodiments of this application, the sound-enhancing headphones further include a mounting structure 2, which is disposed within the receiving cavity 11 and is used to mount a speaker 6. The mounting structure 2 divides the receiving cavity 11 into a front cavity 111 and a rear cavity 112. The headphone housing 1 has a sound outlet 12, which is provided corresponding to the front cavity 111. The mounting structure 2 has a tuning channel 21 that connects the front cavity 111 and the rear cavity 112. The headphone housing 1 has a tuning hole 13 corresponding to the rear cavity 112, which is connected to the outside.

[0057] In this embodiment, the mounting structure 2 is located inside the receiving cavity 11. The mounting structure 2 is used to mount the speaker 6. The speaker 6 can be mounted to the mounting structure 2 by adhesive; the speaker 6 can also be mounted to the mounting structure 2 by snap-fit; or the speaker 6 can be mounted to the mounting structure 2 by screws.

[0058] In this embodiment of the application, the mounting structure 2 divides the receiving cavity 11 into the headphone front cavity 111 and the headphone rear cavity 112. It can be understood that the mounting structure 2 divides the headphone shell 1 into two parts. The inner wall of the first part of the headphone shell 1 and the mounting structure 2 enclose the headphone front cavity 111, and the inner wall of the second part and the mounting structure 2 enclose the headphone rear cavity 112.

[0059] In this embodiment, the mounting structure 2 can be a plate-like structure disposed within the receiving cavity 11, and the speaker 6 is disposed on the side of the mounting structure 2 facing the sound outlet 12; in another embodiment, the mounting structure 2 can be a structure on the earphone housing 1 for mounting the speaker 6, the speaker 6 is mounted on the mounting structure 2, and the speaker 6 divides the receiving cavity 11 into the earphone front cavity 111 and the earphone rear cavity 112.

[0060] In this embodiment of the application, the tuning channel 21 can also be understood as a channel opened on the mounting structure 2, used to connect the front cavity 111 of the earphone and the rear cavity 112 of the earphone.

[0061] In this embodiment, the sound outlet 12 is usually located in the ear canal. The sound outlet 12 allows the sound from the headphones to be transmitted into the ear better. The pressure relief channel 31 makes the air pressure in the front cavity 111 and the rear cavity 112 of the headphones quickly equalize, avoiding abnormal deformation of the speaker 6 diaphragm due to air pressure difference, reducing low frequency distortion and improving the accuracy of the sound.

[0062] The improved sound quality headphones of this embodiment have a mounting structure 2 that divides the receiving cavity 11 into a front cavity 111 and a rear cavity 112. A sound outlet 12 is provided corresponding to the front cavity 111. When the headphones are worn, the sound outlet 12 connects the front cavity 111 to the space inside the ear canal. Since the mounting structure 2 has a tuning channel 21, it connects the front cavity 111 and the rear cavity 112, thus connecting the space inside the ear canal with the rear cavity 112 and balancing the pressure between the space inside the ear canal, the front cavity 111, and the rear cavity 112. Because the headphone shell 1 has a tuning hole 13 corresponding to the rear cavity 112, and the tuning hole 13 is connected to the outside, that is, the rear cavity 112 is connected to the outside, this structure allows for better sound quality control within the ear canal. Both the ear canal space and the front cavity 111 of the earphone are connected to the outside through the tuning hole 13, releasing the pressure inside the ear canal space and the front cavity 111 of the earphone. Since the mounting structure 2 is located inside the receiving cavity 11, and the tuning channel 21 on the mounting structure 2 is also located inside the receiving cavity 11, the tuning channel 21 is not affected by the skin around the ear. When wearing the earphone, the skin will not come into contact with the tuning channel 21. At the same time, the tuning channel 21 connects the front cavity 111 of the earphone and the rear cavity 112 of the earphone, and the tuning hole 13 connects the rear cavity 112 of the earphone to the outside, which can release the pressure inside the ear canal space and the receiving cavity 11. Compared with related technologies, this improves the situation where the skin blocks the tuning hole 13, causing pressure release to be obstructed, resulting in abnormal noise and affecting the sound quality and experience. Therefore, the earphone provided in this application embodiment can optimize the air pressure release path and reduce abnormal noise caused by pressure release obstruction.

[0063] In some possible embodiments of this application, reference is made to Figure 1 , Figure 2 and Figure 4 The headphones that improve sound quality also include a pressure relief component 3, which is located in the tuning channel 21. The pressure relief component 3 includes a pressure relief channel 31, and the two ends of the pressure relief channel 31 are respectively connected to the front cavity 111 and the rear cavity 112 of the headphones.

[0064] In this embodiment, the pressure relief component 3 can be made of flexible materials or composite acoustic materials, such as silicone, foam, or microporous materials.

[0065] In this embodiment, the pressure relief channel 31 of the pressure relief component 3 can be a single through hole or a slit; the pressure relief channel 31 of the pressure relief component 3 can also be multiple through holes or slits. For example, multiple through holes in the pressure relief channel 31 can slow down the pressure release rate and reduce diaphragm overload.

[0066] In this embodiment, the pressure relief component 3 can be glued to the tuning channel 21; the pressure relief component 3 can also be snapped onto the tuning channel 21, and this application does not limit this.

[0067] In this embodiment, the size of the pressure relief component 3 can be adapted to the size of the tuning channel 21 so that the pressure relief component 3 can fit against the inner wall of the tuning channel 21, reducing airflow leakage from the gap between the tuning channel 21 and the pressure relief component 3.

[0068] In this embodiment, the pressure relief channel 31 can be a cylindrical channel, a spiral channel, a long channel, a labyrinth channel, etc., and this application does not limit the comparison.

[0069] The sound-quality-improving headphones of this embodiment include a pressure relief component 3 disposed in a tuning channel 21. The pressure relief channel 31 connects the front cavity 111 and the rear cavity 112 of the headphones. The pressure relief channel 31 can adjust the airflow path between the front cavity 111 and the rear cavity 112 of the headphones, guiding the airflow smoothly, reducing abnormal airflow noise, and improving sound purity. Simultaneously, low-frequency compensation is achieved by controlling the airflow rate, thereby optimizing sound quality.

[0070] In some possible embodiments of this application, reference is made to Figure 1 , Figure 2 and Figure 4 The pressure relief channel 31 includes a first opening 32 and a second opening 33. The first opening 32 is disposed toward the front cavity 111 of the earphone, and the second opening 33 is disposed toward the rear cavity 112 of the earphone. There is an angle between the axis of the first opening 32 and the axis of the second opening 33.

[0071] In this embodiment of the application, the first opening 32 refers to the opening end of the pressure relief channel 31 near the front cavity 111 of the earphone, and the second opening 33 refers to the opening end of the pressure relief channel 31 near the rear cavity 112 of the earphone.

[0072] In this embodiment, the shapes of the first opening 32 and the second opening 33 can be the same or different. The shapes of the first opening 32 and the second opening 33 can be consistent with the cross-sectional shape of the pressure relief channel 31. The shapes of the first opening 32 and the second opening 33 can be circular, elliptical, or rectangular, etc. This application does not limit them.

[0073] In this embodiment of the application, the axis of the first opening 32 refers to the axis passing through the geometric center of the first opening 32; the axis of the second opening 33 refers to the axis passing through the geometric center of the second opening 33.

[0074] In this embodiment of the application, the included angle between the axis of the first opening 32 and the axis of the second opening 33 can be adjusted as needed. For example, the included angle between the axis of the first opening 32 and the axis of the second opening 33 can be between 30° and 150°.

[0075] In this embodiment of the application, the middle part of the pressure relief channel 31 can form a structure that can change the airflow direction, such as an arc transition path, a broken line path, a spiral path, etc., through the included angle between the axis of the first opening 32 and the axis of the second opening 33.

[0076] In this embodiment of the application, the first opening 32 is disposed toward the front cavity 111 of the earphone, which means that the first opening 32 is disposed on one side of the front cavity 111 of the earphone, or the first opening 32 is located inside the front cavity 111 of the earphone; the second opening 33 is disposed toward the rear cavity 112 of the earphone, which means that the second opening 33 is disposed on one side of the rear cavity 112 of the earphone, or the second opening 33 is located inside the rear cavity 112 of the earphone.

[0077] The improved sound quality headphones of this application embodiment have an angle between the axis of the first opening 32 and the axis of the second opening 33. Therefore, the connection line between the pressure relief channel 31 and the second opening 33 is not a straight line, meaning the pressure relief channel 31 has an internal angle. Since the first opening 32 is positioned towards the front cavity 111 of the headphones and the second opening 33 is positioned towards the rear cavity 112 of the headphones, the direction of airflow between the front cavity 111 and the rear cavity 112 of the headphones changes. This slows down the airflow speed through the pressure relief channel 31, resulting in smoother pressure relief, reduced airflow noise, and improved user comfort. Simultaneously, the angled pressure relief channel 31 can diffract and absorb high-frequency sound waves, optimizing sound quality.

[0078] In some possible embodiments of this application, reference is made to Figure 4 , Figure 5 and Figure 6 The mounting structure 2 includes a first limiting surface 22, which is in contact with the circumferential surface of the speaker 6. The tuning channel 21 passes through the first limiting surface 22 along the radial direction of the speaker 6. The surface of the pressure relief component 3 facing the speaker 6 is in contact with the circumferential surface of the speaker 6.

[0079] In this embodiment, the first limiting surface 22 is used to limit the position of the speaker 6 within the receiving cavity 11, and can also be used to mount the speaker 6. For example, the peripheral surface of the speaker 6 and the first limiting surface 22 can be connected by adhesive.

[0080] In this embodiment, the first limiting surface 22 is attached to the circumferential surface of the speaker 6, and a transition fit (such as a gap between 0 and 0.1 mm) can be formed between the first limiting surface 22 and the circumferential surface of the speaker 6; a micro interference fit (such as an interference amount less than or equal to 0.05 mm) can also be formed between the first limiting surface 22 and the circumferential surface of the speaker 6.

[0081] In this embodiment, the tuning channel 21 passes through the first limiting surface 22 along the radial direction of the speaker 6, which can be understood as the axis of the tuning channel 21 in the radial direction of the speaker 6 being parallel to the radial direction of the speaker 6.

[0082] In this embodiment, when the first limiting surface 22 is in contact with the circumferential surface of the speaker 6, the shape of the first limiting surface 22 is adapted to the circumferential surface of the speaker 6. The radial direction of the speaker 6 can be understood as the radial direction of the first limiting surface 22 having a circular outline. For example, the speaker 6 has a circular structure, and the first limiting surface 22 has an annular structure.

[0083] The improved sound quality headphones of this application embodiment have a first limiting surface 22 annularly arranged inside the mounting structure 2. The peripheral surface of the first limiting surface is in contact with the peripheral outer surface of the speaker 6, thereby forming a surface-to-surface contact between the mounting structure 2 and the speaker 6, allowing the speaker 6 to be mounted on the mounting structure 2 and limiting its position. The surface of the pressure relief component 3 facing the speaker 6 is in contact with the circumferential surface of the speaker 6, that is, the pressure relief component 3 and the speaker 6 are arranged adjacent to each other and in contact with each other. This optimizes space utilization and allows the mounting structure 2 and the speaker 6 to limit and position the pressure relief component 3, reducing costs.

[0084] In some possible embodiments of this application, reference is made to Figure 4 , Figure 5 and Figure 6 The earphone housing 1 has a receiving groove 14 that communicates with the tuning channel 21. The receiving groove 14 extends in a direction away from the earphone rear cavity 112. One end of the pressure relief member 3 is disposed in the receiving groove 14, and the other end of the pressure relief member 3 extends into the tuning channel 21.

[0085] In this embodiment of the application, the receiving groove 14 can be used to install the pressure relief component 3. The receiving groove 14 is formed by extending from the tuning channel 21 in a direction away from the rear cavity 112 of the headphone. It can also be understood that the receiving groove 14 is located on the headphone shell 1 on the side of the front cavity 111 of the headphone, corresponding to the position of the tuning channel 21.

[0086] In this embodiment, a portion of the pressure relief component 3 is disposed within the receiving groove 14, and another portion is disposed within the tuning channel 21. The portion of the pressure relief component 3 disposed within the receiving groove 14 can be fixedly connected to the receiving groove 14 by adhesive.

[0087] In this embodiment, the shape of the receiving groove 14 is adapted to the shape of the pressure relief member 3 disposed in the portion of the receiving groove 14, and the pressure relief member 3 and the receiving groove 14 can be sealed together.

[0088] In this embodiment of the application, the first opening 32 may be located in the receiving groove 14. When the first opening 32 is located in the receiving groove 14, the receiving groove 14 may communicate with the headphone front cavity 111. The first opening 32 is disposed on the side where the receiving groove 14 and the headphone front cavity 111 communicate, so that the first opening 32 and the headphone front cavity 111 communicate.

[0089] The improved sound quality headphones of this application embodiment have a receiving groove 14 formed by extending from the tuning channel 21 away from the rear cavity 112 of the headphones, and one end of the pressure relief member 3 is disposed in the receiving groove 14, while the other end of the pressure relief member 3 extends into the tuning channel 21. This increases the size of the pressure relief member 3 in the direction of the arrangement of the tuning channel 21 and the receiving groove 14, that is, the cross-sectional size of the pressure relief member 3 in the direction extending from the tuning channel 21 to the receiving groove 14 is increased. This lengthens the propagation path of sound waves and airflow in the pressure relief channel 31, effectively canceling the sound wave interference between the front cavity 111 and the rear cavity 112 of the headphones, thus improving sound quality.

[0090] In some possible embodiments of this application, reference is made to Figure 4 , Figure 5 and Figure 6 The mounting structure 2 also includes a second limiting surface 23, which is used to limit the movement of the speaker 6 along the first limiting surface 22; the first limiting surface 22 and the first opening 32 are located on both sides of the extension surface of the second limiting surface 23.

[0091] In this embodiment, the second limiting surface 23 is used to restrict the movement of the speaker 6 along the first limiting surface 22. The second limiting surface 23 and the first limiting surface 22 have an included angle, which can also be understood as forming an orthogonal constraint between them. For example, the included angle between the second limiting surface 23 and the first limiting surface 22 can be between 80° and 100°, and this application does not limit this angle.

[0092] In this embodiment, the extended surface of the second limiting surface 23 refers to a virtual plane that extends infinitely from the second limiting surface 23, with the first limiting surface 22 and the first opening 32 located on opposite sides of this virtual plane. Alternatively, the first limiting surface 22 can be understood as having a circular outline, with the projections of the first limiting surface 22 and the first opening 32 along the radial direction of this circular outline located on opposite sides of the projection of the second limiting surface 23, meaning the projections of the first limiting surface 22 and the first opening 32 do not overlap.

[0093] The improved sound quality headphones of this application embodiment have the following features: the first limiting surface 22 and the peripheral surface of the speaker 6 are in close contact, and the first limiting surface 22 and the first opening 32 are located on both sides of the extension surface of the second limiting surface 23. This can be understood as the peripheral surface of the speaker 6 and the first opening 32 being located on both sides of the extension surface of the second limiting surface 23. Since the second limiting surface 23 is used to restrict the movement of the speaker 6 along the first limiting surface 22, the speaker 6 cannot move to the other side of the second limiting surface 23, that is, the side where the first opening 32 is located. Thus, the speaker 6 and the first opening 32 will not interfere with each other, improving the stability of the first opening 32 connecting to the front cavity 111 of the headphones.

[0094] In some possible embodiments of this application, reference is made to Figure 4 The headphones that improve sound quality also include a first tuning mesh 4, which is disposed in the second opening 33 of the pressure relief component 3.

[0095] In this embodiment, the first tuning mesh 4 can be made of materials such as nickel-titanium alloy, gold-plated copper, nylon, or polyester fiber. This application does not limit the materials used.

[0096] In this embodiment, the first tuning mesh 4 includes multiple mesh openings. The density of the mesh openings can be adjusted according to the material of the first tuning mesh 4 or as needed. This application does not limit this.

[0097] In this embodiment of the application, a slot can be provided at the second opening 33 of the pressure relief component 3, and the edge of the first tuning mesh 4 is pressed into the slot by an interference fit.

[0098] In another embodiment, the first tuning mesh 4 can be attached to the second opening 33 by adhesive.

[0099] In this embodiment of the sound-quality-improving headphones, a first tuning mesh 4 is disposed at the second opening 33 of the pressure relief component 3. After sound waves and airflow pass through the pressure relief channel 31, they can be buffered by the first tuning mesh 4 before entering the rear cavity 112 of the headphones. The first tuning mesh 4 can smooth the airflow, significantly reducing abnormal noise and airflow noise generated when wearing or removing the headphones, thus improving the user experience. At the same time, the first tuning mesh 4 can buffer changes in air pressure, helping the diaphragm of the speaker 6 to work stably and improving the dynamic range and transient performance of the music.

[0100] It should be added that, in this embodiment of the application, a second tuning mesh 5 is also included. The second tuning mesh 5 covers the tuning hole 13. The second tuning mesh 5 can be used to block external debris from entering the earphone rear cavity 112 through the tuning hole 13. The second tuning mesh 5 can also buffer the air exchange between the earphone rear cavity 112 and the outside world, reduce pressure release, and improve the stability of the earphone rear cavity 112.

[0101] In some possible embodiments of this application, reference is made to Figure 4 , Figure 5 and Figure 6 The mounting structure 2 has a first side close to the sound outlet 12, and the tuning channel 21 is positioned opposite the first side.

[0102] In this embodiment, the first side refers to the area on the mounting structure 2 near the headphone outlet, which is usually directly facing the ear canal; the tuning channel 21 is located on the other side of the mounting structure 2 opposite to the first side (i.e., facing away from the ear canal).

[0103] The improved sound quality headphones of this application embodiment have a mounting structure 2 with a first side close to the sound outlet 12, and a tuning channel 21 is disposed opposite to the first side. It can be understood that the tuning channel 21 and the sound outlet 12 are disposed on opposite sides of the mounting structure 2. This can increase the distance between the tuning channel 21 and the sound outlet 12, which can extend the propagation path of sound waves in the front cavity 111 of the headphones, form a more complete acoustic phase adjustment, and optimize the sound quality.

[0104] In some possible embodiments of this application, the outer wall of the pressure relief component 3 is sealed to the inner wall of the tuning channel 21.

[0105] In this embodiment, the outer wall of the pressure relief component 3 and the inner wall of the tuning channel 21 can be sealed together by means of interference fit, adhesive sealing or ultrasonic welding.

[0106] In the improved sound quality headphones of this application embodiment, since the outer wall of the pressure relief component 3 is sealed to the inner wall of the tuning channel 21, the sound waves and airflow between the front cavity 111 and the rear cavity 112 of the headphones can only flow through the pressure relief channel 31 of the pressure relief component 3, reducing bypass leakage interference with the tuning effect.

[0107] This application provides an earphone module, which includes an earphone case and earphones with improved sound quality as described above, wherein the earphones with improved sound quality are housed inside the earphone case.

[0108] In this embodiment, the sound-enhancing headphones are housed within a headphone case. Here, the headphone case may simply function as a container for the sound-enhancing headphones; alternatively, it may also include charging the headphones in addition to accommodating them. This embodiment does not impose any limitations on this. In one possible implementation provided by this embodiment, the headphone case, besides accommodating the sound-enhancing headphones, also includes charging them.

[0109] The headphone module of this application embodiment, since it includes the headphone with improved sound quality provided in this application embodiment, has the same technical effect. That is, it can optimize the air pressure release path and reduce abnormal noise caused by pressure release obstruction.

[0110] The sequence numbers of the embodiments in this application are for descriptive purposes only and do not represent the superiority or inferiority of the embodiments. The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made based on the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
