Description

Technical Field

[0001] The present application relates to the technical field of audio equipment, and in particular to an earplug and a headset. Background Art

[0002] As a necessity for users to listen to music and make calls, earphones are used frequently and for a long time. In-ear earphones usually include earplugs and earphone bodies. Among them, earplugs, as an important component of in-ear earphones, have an important impact on the wearing comfort and stability of the earphones.

[0003] However, the earplug structure currently available on the market cannot make the earphones meet the requirements of wearing comfort and wearing stability at the same time. Utility Model Content

[0004] The present application provides an earplug and an earphone. The earplug and the earphone including the earplug can take into account both wearing comfort and wearing stability.

[0005] In a first aspect, an embodiment of the present application provides an earplug. The earplug includes a base, a support member, and a contact member; the base has a first through hole; the support member is fixedly connected to the base, the support member has a second through hole, and the second through hole is connected to the first through hole; the contact member is sleeved on a side of the support member facing away from the base, the contact member has a third through hole, and the third through hole is connected to the second through hole; the hardness of the base and the support member is greater than the hardness of the contact member.

[0006] In an embodiment of the present application, the earplug may include a base, a support member, and a contact member connected in sequence. When the user uses the earplug, at least a portion of the earplug may enter the user's ear canal. The contact member is sleeved on a side of the support member facing away from the fixing seat, and the contact member may contact the user's ear canal. Both the support member and the contact member may be squeezed by the user's ear canal.

[0007] Since the hardness of the contact piece is relatively small, the contact piece is easily deformed after being squeezed by the user's ear canal, so that the contact piece can better adapt to the shape of the user's ear canal; and after being squeezed by the user's ear canal, the reaction force of the contact piece on the user's ear canal is relatively small, and it will not cause pressure on the user's ear canal, which is conducive to improving the user's wearing comfort. The hardness of the support piece is relatively large, and the deformation of the support piece after being squeezed by the user's ear canal is relatively small. Therefore, the support piece has a certain supporting effect on the contact piece, which can make the contact piece fit the user's ear canal more closely, so that the earplug is not easy to fall off from the user's ear canal, and the earplug has better wearing stability. It can be understood that the earplug provided in the embodiment of the present application can take into account both good wearing comfort and wearing stability.

[0008] In addition, the base has a relatively high hardness. The earplug can be installed on an electronic device such as an earphone through the base. For example, the base can be snap-connected with other structural parts on the earphone.

[0009] In some embodiments, the base has a harderness that is greater than the support.

[0010] In this embodiment, the base of the earplug can have a greater hardness, so that the base and other structural parts on the earphone are stably connected, and the earplug is not likely to fall off.

[0011] In some embodiments, the base, the support member, and the contact member are all flexible members; the hardness of the base is in the range of 60 to 80HA. It is understandable that "HA" means Shore A hardness, which refers to the hardness value of the material measured by using a Shore A durometer, in degrees. For example, if the hardness value of the material tested using a Shore A durometer is 70 degrees, it is marked as: 70HA. The hardness of the base is in the range of 60 to 80HA, so that the hardness of the base is relatively appropriate. On the one hand, the base can have a certain deformation ability, which is convenient for clamping with other structural parts on the earphone; on the other hand, the base can have a certain hardness, and the stability of the base clamping with other structural parts on the earphone is better, and the earplug is not easy to fall off.

[0012] In some embodiments, the hardness of the support member is in the range of 30 to 40HA. In this way, the hardness of the support member is relatively appropriate. On the one hand, the support member can support the contact member so that the contact member fits the user's ear canal more closely, thereby making the earplug have better wearing stability; on the other hand, after the support member is squeezed by the user's ear canal, the reaction force on the user's ear canal is relatively small, and will not cause strong pressure on the user's ear canal, thereby facilitating the wearing comfort of the earplug.

[0013] In some embodiments, the hardness of the contact piece is less than 30HA. In this way, the contact piece is relatively soft. The contact piece is easily deformed after being squeezed by the user's ear canal, and will not cause pressure on the user's ear canal, so that the earplug can have better wearing comfort.

[0014] In some embodiments, the material of the support member is a noise reduction material.

[0015] It is understandable that the material of the contact piece is usually sponge, and since the sponge has a loose and porous structure, it is easy to cause the earplug to leak sound. The earplug has a poor ability to isolate noise. In this embodiment, the support piece is made of noise reduction material, so that when the user wears the earplug, the support piece can better isolate noise, which is conducive to improving the noise reduction effect of the earplug, that is, improving the passive isolation performance of the earplug. In this way, the earplug can take into account good wearing comfort, wearing stability and noise reduction effect.

[0016] In some embodiments, the base is made of silicone. It is understandable that in this embodiment, the base can be made of hard silicone. The manufacturing process of the base is relatively simple and the cost is low.

[0017] In some embodiments, the material of the support member includes silicone and polyurethane. It is understandable that in this embodiment, the support member can be made of soft silicone or polyurethane. The support member can meet its hardness requirements and has a good noise reduction effect.

[0018] In some embodiments, the contact member is made of sponge. In this embodiment, the contact member made of sponge can better adapt to the shape of the user's ear canal, so that the earplug has better wearing comfort.

[0019] In some embodiments, the base, the support member and the contact member are an integrally formed structural member. In this way, the base, the support member and the contact member are tightly connected, and the sealing performance of the earplug is good, and sound leakage is not likely to occur.

[0020] In some embodiments, the support member includes a fixing portion and a supporting portion, the first through hole is provided in the fixing portion; the fixing portion is connected between the base and the contact member, the supporting portion is fixedly connected to the fixing portion, the supporting portion extends to the side of the base through the side of the fixing portion, and is spaced apart from the side of the fixing portion and the side of the base.

[0021] It can be understood that, in this embodiment, a partial structure of the support portion can surround the fixed portion, and be opposite to and spaced from the fixed portion, that is, an air gap can exist between the partial structure of the support portion and the fixed portion. A partial structure of the support portion can surround the base, and be spaced from the base, that is, an air gap can exist between the partial structure of the support portion and the base. In this way, there can be a buffer space between the support portion and the base and the fixed portion. When the user wears the earplug, the support portion of the support member is easily deformed under the squeeze of the user's ear canal, so that the earplug is not likely to cause pressure on the user's ear canal, which is conducive to improving the wearing comfort of the earplug.

[0022] In some embodiments, the fixing portion includes a top surface and a bottom surface disposed opposite to each other, the top surface of the fixing portion is fixedly connected to the contact piece, and the bottom surface of the fixing portion is fixedly connected to the base; in a direction perpendicular to the central axis of the first through hole, the distance between the central axis of the first through hole and the outer edge of the top surface of the fixing portion is S1, the distance between the central axis of the first through hole and the outer edge of the bottom surface of the fixing portion is S2, and S1 <S2。

[0023] In this embodiment, when cut along a direction parallel to the top of the earplug toward the bottom of the earplug, the cross-section of the fixing portion of the support member can be roughly a trapezoidal structure with a "small top and large bottom". In this way, the area of ​​the bottom surface of the fixing portion can be larger. Since the bottom surface of the fixing portion is connected to the first surface of the base, the area of ​​the first surface of the base can also be increased accordingly. On the one hand, the connection area between the fixing portion of the support member and the base is larger, and the connection firmness between the fixing portion and the base is better; on the other hand, the lateral dimension of the base (that is, the dimension in the direction perpendicular to the central axis of the first through hole) can also be increased accordingly, so that the space of the first through hole of the base can be increased accordingly, so that when the earplug is connected to other structural members on the earphone, the first through hole of the base can be used to accommodate more structures on the earphone.

[0024] In some embodiments, in a direction perpendicular to the central axis of the first through hole, the distance between the outer edge of the top surface of the fixing portion and the outer edge of the contact piece is S3, the distance between the outer edge of the bottom end surface of the supporting portion and the outer edge of the contact piece is S4, S3 <S4。

[0025] It is understandable that the material of the contact piece is usually sponge, which is a loose and porous structure, which can easily cause sound leakage in the earplug. In this embodiment, by reducing the thickness of the bottom of the contact piece to reduce the proportion of the porous structure on the bottom of the earplug, it is not easy for sound to leak at the bottom of the earplug when the user wears the earplug.

[0026] In some embodiments, the distance S4 between the outer edge of the bottom end surface of the support portion and the outer edge of the contact piece is in the range of 0.85 mm to 1.2 mm. In this way, the thickness of the bottom of the contact piece is appropriate, the contact piece is not likely to cause pressure on the user's ear canal, the wearing comfort requirement can be met, and the risk of sound leakage of the earplug can be reduced.

[0027] In some embodiments, in a direction perpendicular to a central axis of the first through hole, a thickness of the fixing portion is greater than a thickness of the supporting portion.

[0028] In this embodiment, on the one hand, in the direction perpendicular to the central axis of the first through hole, the thickness of the fixing portion is relatively large, so that the connection area between the fixing portion and the contact piece is relatively large, which can not only improve the connection firmness between the fixing portion and the contact piece, but also help to improve the sealing performance between the fixing portion and the contact piece, and reduce the risk of sound leakage in the earplug. On the other hand, in the direction perpendicular to the central axis of the first through hole, the thickness of the supporting portion is relatively small, so that the supporting portion is more likely to deform after being squeezed. When the user wears the earplug, the reaction force of the supporting portion on the user's ear canal is relatively small, so that the supporting portion and the earplug are not likely to cause pressure on the user's ear canal, which is conducive to improving the wearing comfort of the earplug.

[0029] In some embodiments, in a direction perpendicular to the central axis of the first through hole, the width of the top surface of the fixing portion is in a range of 0.8 mm to 1.0 mm. In this way, in a direction perpendicular to the central axis of the first through hole, the thickness of the fixing portion is appropriate, and the connection firmness and sealing between the fixing portion and the contact member are good.

[0030] In some embodiments, in a direction perpendicular to the central axis of the first through hole, the width of the support portion is in a range of 0.3 mm to 0.4 mm. In this way, in a direction perpendicular to the central axis of the first through hole, the width of the support portion of the support member is appropriate, and the support member is not likely to cause pressure on the user's ear canal, which can meet the wearing comfort requirements. It is understandable that in a direction perpendicular to the central axis of the first through hole, the width of the support portion of the support member at each location is in a range of 0.3 mm to 0.4 mm, and the widths at each location may be the same or different.

[0031] In some embodiments, in a direction perpendicular to the central axis of the first through hole, the distance between the central axis of the first through hole and the outer edge of the top end surface of the support portion is S5, the distance between the central axis of the first through hole and the outer edge of the bottom end surface of the support portion is S6, S5 <S6。

[0032] It can be understood that, in this embodiment, the support portion of the support member can be roughly umbrella-shaped. From the top of the support portion to the bottom of the support portion, the support portion can gradually move away from the central axis of the first through hole. In this way, when the user wears the earplug, the bottom of the support portion can fit the user's ear canal more closely, thereby reducing the risk of sound leakage from the earplug.

[0033] In some embodiments, the base includes a first surface and a second surface disposed opposite to each other, the first surface of the base is fixedly connected to the support member; in a direction perpendicular to the central axis of the first through hole, the distance between the central axis of the first through hole and the outer edge of the first surface of the base is S7, the distance between the central axis of the first through hole and the outer edge of the second surface of the base is S8, S7 <S8。

[0034] It can be understood that in this embodiment, when the base is cut along the direction parallel to the top of the earplug toward the bottom of the earplug, the cross section of the base can be roughly a "small top, large bottom" structure. The lateral dimension of the bottom of the base (i.e., the dimension in the direction perpendicular to the central axis of the first through hole) can be larger, so that the space of the first through hole of the base can be correspondingly increased, so that when the earplug is connected to other structural parts on the earphone, the first through hole of the base can be used to accommodate more structures on the earphone.

[0035] In some embodiments, the earplug further includes an anti-scale net, and the anti-scale net is disposed in the first through hole.

[0036] In this embodiment, when the earplug is connected to other structural parts on the earphone, the anti-scale net can prevent earwax, impurities, etc. on the outside of the earplug from entering the interior of the earphone and affecting the reliability of the earphone.

[0037] In some embodiments, the base and the anti-scaling net are integrally formed structural parts, so that the molding process of the base and the anti-scaling net can be simplified, which is conducive to reducing the cost of the base and the anti-scaling net.

[0038] In a second aspect, an embodiment of the present application provides an earphone, which includes an earphone body and the above-mentioned earplug, wherein the base of the earplug is mounted on the earphone body, and the first through hole of the base is connected to the sound outlet of the earphone body.

[0039] In the embodiment of the present application, the earplug is applied to the earphone, which can improve the wearing comfort and wearing stability of the earphone. The sound emitted by the sound-emitting element inside the earphone body can be transmitted through the sound outlet of the earphone body and the first through hole of the earplug.

[0040] In some embodiments, the earphone body includes an ear shell, the ear shell is provided with a sound outlet of the earphone body, and the base of the earplug is fixed to the ear shell; the earphone body also includes a first acoustic element and a second acoustic element, the first acoustic element and the second acoustic element are installed in the internal space of the ear shell, the first acoustic element and the second acoustic element are spaced apart, and the first acoustic element and the second acoustic element are both partially located in the first through hole of the base.

[0041] It is understandable that in this embodiment, the first acoustic element and the second acoustic element can be arranged close to the earplug. In this way, when the user wears the earphone, the first acoustic element and the second acoustic element can be closer to the user's ear canal, and the sound emitted by the first acoustic element and / or the second acoustic element can be better transmitted to the user's ear canal, thereby helping to improve the sound effect of the earphone.

[0042] In some embodiments, the arrangement direction of the first acoustic element and the second acoustic element is perpendicular to the central axis of the first through hole. In this way, the first acoustic element and the second acoustic element can reasonably utilize the internal space of the ear shell, which is conducive to reducing the size of the ear shell, thereby facilitating the miniaturization of the earphone.

[0043] In some embodiments, the first acoustic element is a microphone, and the second acoustic element is a high-frequency speaker. In this embodiment, the first acoustic element can be a microphone, which is used to convert sound signals into electrical signals so that the earphone can receive sound. The second acoustic element can be a high-frequency speaker, which is used to transmit high-frequency sound waves.

[0044] In some embodiments, the ear shell includes a main body and a mounting portion, the mounting portion is fixedly connected and protrudes from the main body, the mounting portion is at least partially located in the first through hole of the base, and is snap-connected with the base; the main body has a first sound outlet hole and a second sound outlet hole that are spaced apart, the first sound outlet hole and the second sound outlet hole are both located on the inner side of the mounting portion, the first sound outlet hole and the second sound outlet hole are both connected to the first through hole of the base and the internal space of the main body, and the first sound outlet hole and the second sound outlet hole are both part of the sound outlet of the earphone body; the first acoustic element is partially located in the first sound outlet hole, and the second acoustic element is partially located in the second sound outlet hole.

[0045] In this embodiment, the first sound outlet hole and the second sound outlet hole can be connected to the outside of the earphone through the first through hole of the earplug. In this way, the sound can be transmitted between the first acoustic element and the outside of the earphone through the first sound outlet hole. The sound can be transmitted between the second acoustic element and the outside of the earphone through the second sound outlet hole. For example, the sound emitted by the second acoustic element can be transmitted to the outside of the earphone through the second sound outlet hole.

[0046] In some embodiments, the main body has a first protrusion, the first protrusion is arranged around the first sound outlet hole, and a portion of the first protrusion is located between the first sound outlet hole and the second sound outlet hole.

[0047] In this embodiment, the first protrusion is provided to surround the first sound outlet hole, so that the first sound outlet hole is separated from the second sound outlet hole, thereby reducing the risk of interference between the first acoustic element and the second acoustic element.

[0048] In some embodiments, the main body has a second protrusion, and a portion of the second protrusion is located between the first sound outlet hole and the second sound outlet hole.

[0049] In this embodiment, the second protruding portion is located between the first sound outlet hole and the second sound outlet hole, which can separate the second sound outlet hole from the first sound outlet hole, thereby reducing the risk of interference between the first acoustic element and the second acoustic element.

[0050] In some embodiments, the second protrusion is arc-shaped, and the second protrusion partially surrounds the second sound outlet hole. It is understandable that the second protrusion can surround a part of the structure of the second sound outlet hole, but not another part of the structure of the second sound outlet hole. In this way, the second protrusion can avoid other structural parts on the earphone.

[0051] In some embodiments, the ear shell further includes a dustproof net, which is installed on the inner side of the mounting portion and covers the second sound outlet and the first sound outlet. In this way, the dustproof net can prevent earwax and impurities outside the earphone from entering the interior of the earphone body through the sound outlet of the earphone body, thereby affecting the normal operation of the earphone.

[0052] In some embodiments, the dustproof net surrounds the first sound outlet hole and the second sound outlet hole, and a portion of the dustproof net is disposed opposite to the second protrusion.

[0053] In this embodiment, the dustproof net and the second protrusion can surround the second sound outlet hole together, so that the second sound outlet hole is separated from the first sound outlet hole, thereby reducing the risk of interference between the first acoustic element and the second acoustic element.

[0054] In some embodiments, the earphone body also includes a third acoustic element, which is arranged in the internal space of the ear shell and is a low-frequency speaker; the main body also has a third sound hole that is spaced apart from the first sound hole and the second sound hole, and the sound emitted by the third acoustic element is transmitted through the third sound hole, and the third sound hole is a part of the sound outlet of the earphone body; the second raised portion is located between the second sound hole and the third sound hole.

[0055] It is understandable that the second acoustic element can be used to propagate high-frequency sound waves, and the third acoustic element can be used to propagate low-frequency sound waves. Among them, high-frequency sound waves can be transmitted through the second sound outlet hole, and low-frequency sound waves can be transmitted through the third sound outlet hole. In this embodiment, the second protrusion can separate the second sound outlet hole from the third sound outlet hole, so that the high-frequency sound waves passing through the second sound outlet hole can be separated from the low-frequency sound waves passing through the third sound outlet hole, reducing the risk of crosstalk between high-frequency sound waves and low-frequency sound waves.

[0056] In some embodiments, the main body further has a fourth sound hole, which is spaced apart from the first sound hole, the second sound hole, and the third sound hole, and the sound emitted by the third acoustic element is transmitted through the fourth sound hole, and the fourth sound hole is a part of the sound outlet of the earphone body; the second raised portion is located between the second sound hole and the fourth sound hole; the main body further has a third raised portion, which is connected between the first raised portion and the second raised portion, and the third sound hole and the fourth sound hole are located on both sides of the third raised portion.

[0057] In this embodiment, the second protrusion can separate the second sound outlet hole from the fourth sound outlet hole, so that the high-frequency sound waves passing through the second sound outlet hole can be separated from the low-frequency sound waves passing through the fourth sound outlet hole, reducing the risk of crosstalk between the high-frequency sound waves and the low-frequency sound waves. At the same time, by providing the third protrusion, on the one hand, the third protrusion is connected between the first protrusion and the second protrusion, which can enhance the overall structural strength of the ear shell; on the other hand, the third protrusion can separate the third sound outlet hole from the fourth sound outlet hole, so that the sound transmitted through the third sound outlet hole and the sound transmitted through the fourth sound outlet hole are not easily interfered.

[0085] In the embodiments of the present application, "and / or" is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0086] In the embodiments of the present application, the terms "parallel" and "perpendicular" are defined in terms of the current process level, rather than being absolutely strict definitions in a mathematical sense. A small amount of deviation is allowed, and approximately parallel, approximately perpendicular, etc. are all acceptable. For example, A and B are parallel, which means that A and B are parallel or approximately parallel, and the angle between A and B can be between 0° and 10°. For example, A and B are perpendicular, which means that A and B are perpendicular or approximately perpendicular, and the angle between A and B can be between 80° and 100°.

[0087] References to "some embodiments" and the like described in this specification mean that one or more embodiments of the present application include specific features, structures or characteristics described in conjunction with the embodiment. Thus, statements appearing in different places in this specification, such as "in some embodiments", "in some other embodiments", "in some other embodiments", etc., do not necessarily all refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in another way. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in another way.

[0088] It is to be understood that the specific embodiments described herein are only used to explain the relevant embodiments, rather than to limit the embodiments. It is also to be understood that, for ease of description, only the parts related to the embodiments are shown in the drawings.

[0089] It can be understood that the embodiments and features in the embodiments in this application can be combined with each other without conflict.

[0090] The present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0091] Please refer to Figure 1A and Figure 1B , Figure 1A is a schematic diagram of the structure of an earphone 100 provided in an embodiment of the present application. Figure 1B yes Figure 1A The structure diagram of the earphone 100 shown in FIG. 1 is another perspective view. It can be understood that Figure 1A The following figures and the related drawings only schematically illustrate some components of the headset 100, and the actual shapes, sizes, positions and structures of these components are not subject to the present invention. Figure 1A and the accompanying drawings below.

[0092] In the embodiment of the present application, the earphone 100 may include an earphone body 10 and an earplug 20. The earplug 20 may be installed in the earphone body 10. The earphone body 10 is the main structure of the earphone 100, and other components of the earphone 100 may be arranged in the earphone body 10. The earplug 20 is used to place at least part of the earplug 20 into the ear canal of the user when the user wears the earphone 100.

[0093] The earplug 20 may have a sound outlet channel 201. The sound outlet channel 201 may pass through the earplug 20 in the direction from the top to the bottom of the earplug 20. It is understood that when the earplug 20 is installed on the earphone body 10, the bottom of the earplug 20 is closer to the earphone body 10 than the top of the earplug 20. When the user wears the earphone 100, the top of the earplug 20 can go deeper into the user's ear canal than the bottom of the earplug 20.

[0094] In an embodiment of the present application, the earphone 100 may be an in-ear earphone or a semi-in-ear earphone. For example, the earphone 100 may be a true wireless stereo (TWS) earphone, or may be a wired earphone. Among them, the wireless earphone may be connected to the terminal device by electromagnetic waves. For example, a Bluetooth earphone, an infrared earphone, etc. Among them, the wired earphone may be connected to the terminal device by wire. The present application does not strictly limit the type of the earphone 100.

[0095] Please refer to Figure 1B and Figure 2 , Figure 2 for Figure 1B The headset 100 is shown in a partially exploded view in some embodiments.

[0096] In some embodiments, the earphone body 10 may include an ear shell 11. The earplug 20 may be fixed to the ear shell 11. Exemplarily, the ear shell 11 may have a main body 111 and a mounting portion 112. The mounting portion 112 is fixedly connected and protrudes from the main body 111. The mounting portion 112 may be snap-fitted with the earplug 20, so that the earplug 20 may be fixed to the ear shell 11. In some other embodiments, the ear shell 11 may not include the mounting portion 112, and the earplug 20 may be fixed to the ear shell 11 by bonding or other methods.

[0097] For example, the main body 111 and the mounting portion 112 may be an integrally formed structure, thereby simplifying the process. In other embodiments, the main body 111 and the mounting portion 112 may also be fixedly connected by bonding, clamping, etc. to form a whole.

[0098] Please refer to Figures 3 to 5 , Figure 3 yes Figure 1A The structure diagram of the earplug 20 in some embodiments is shown. Figure 4 yes Figure 3 The structure diagram of the earplug 20 shown in FIG. 2 is shown in FIG. 2 from another angle. Figure 5 yes Figure 3 The earplug 20 is shown in a partially exploded view in some embodiments.

[0099] In some embodiments, the earplug 20 may include a base 21, a support member 22, and a contact member 23. Exemplarily, the sound outlet channel 201 of the earplug 20 may pass through the base 21, the support member 22, and the contact member 23. Among them, the support member 22 is fixedly connected to the base 21. The contact member 23 may be sleeved on the side of the support member 22 facing away from the base 21. The contact member 23 may be fixedly connected to the side surface of the support member 22 facing away from the base 21. When the user wears the earphone 100, the earplug 20 may enter the user's ear canal, the contact member 23 at least partially contacts the user's ear canal, and the support member 22 and the contact member 23 are squeezed by the user's ear canal.

[0100] Please refer to Figures 5 to 6B , Fig. 6A yes Figure 5 The schematic structural diagram of the base 21 shown in FIG. Figure 6B yes Figure 5 The shown structure of the base 21 is shown at another angle.

[0101] In some embodiments, in the direction from the top of the earplug 20 to the bottom of the earplug 20, the base 21 may include a first surface 211 and a second surface 212 disposed opposite to each other. The first surface 211 of the base 21 is used to fix the support member 22. The base 21 may also include a side surface 214. The side surface 214 of the base 21 is connected between the first surface 211 of the base 21 and the second surface 212 of the base 21.

[0102] Exemplarily, the base 21 may have a first through hole 210. The first through hole 210 penetrates the base 21 in a direction from the top of the earplug 20 to the bottom of the earplug 20. For example, the first through hole 210 may penetrate the first surface 211 and the second surface 212 of the base 21. The side surface 214 of the base 21 may be arranged around the first through hole 210. It is understood that the central axis A1-A1 of the first through hole 210 may be parallel to the direction from the top of the earplug 20 to the bottom of the earplug 20.

[0103] For example, the base 21 may be annular. For example, when cut along a direction perpendicular to the central axis A1 - A1 of the first through hole 210 , the cross section of the base 21 may be substantially in the shape of a racetrack.

[0104] Exemplarily, the base 21 may have a slot 215. The opening of the slot 215 may be located on the inner surface of the base 21 (i.e., the hole wall of the first through hole 210 of the base 21). It is understood that the slot 215 may be recessed from the inner surface of the base 21 in a direction away from the central axis A1-A1 of the first through hole 210. The slot 215 may be in communication with the first through hole 210 of the base 21.

[0105] Exemplarily, the number of the card slots 215 may be two, and the two card slots 215 may be arranged opposite to each other.

[0106] In some embodiments, the earplug 20 may further include an anti-scaling net 213. The anti-scaling net 213 may be disposed in the first through hole 210 of the base 21. The anti-scaling net 213 may be fixedly connected to the hole wall of the first through hole 210 of the base 21 (ie, the inner surface of the base 21).

[0107] Exemplarily, one side surface of the anti-scale net 213 can be connected and flush with the first surface 211 of the base 21. The anti-scale net can have at least one sound outlet hole 2131. The sound outlet hole 2131 can penetrate the anti-scale net 213 and communicate with the first through hole 210 of the base 21. The sound emitted by the earphone body 10 can be transmitted through the sound outlet hole 2131 of the anti-scale net 213, and the anti-scale net 213 can prevent earwax, impurities, etc. outside the earphone 100 from entering the interior of the earphone body 10 and affecting the normal operation of the earphone 100, thereby helping to improve the reliability of the earphone 100.

[0108] In some embodiments, the base 21 and the anti-scaling net 213 may be integrally formed structural parts, thereby simplifying the molding process of the base 21 and the anti-scaling net 213, which is conducive to reducing the cost of the base 21 and the anti-scaling net 213. In other embodiments, the base 21 and the anti-scaling net 213 may also be fixedly connected by bonding, clamping, etc. to form a whole.

[0109] Please refer to Figure 5 and Figure 7 , Figure 7 yes Figure 3 The partial cross-sectional structure diagram of the earplug 20 shown is cut along the AA line. Figure 7 It mainly shows a schematic diagram of the assembly structure of the base 21 of the earplug 20 and the support member 22 of the earplug 20 .

[0110] In some embodiments, the support member 22 may include a fixing portion 221 and a supporting portion 222 . Figure 7 In the figure, dotted lines are used to exemplarily distinguish the fixed portion and the supporting portion 222 of the support member 22. The fixed portion 221 is fixedly connected to the base 21. Exemplarily, the fixed portion 221 of the support member 22 may include a top surface 2211 and a bottom surface 2212 that are arranged opposite to each other. The bottom surface 2212 of the fixed portion 221 is fixedly connected to the base 21, for example, the bottom surface 2212 of the fixed portion 221 may be fixed to the first surface 211 of the base 21. The fixed portion 221 of the support member 22 may also include a side surface 2213. The side surface 2213 of the fixed portion 221 is connected between the top surface 2211 of the fixed portion 221 and the bottom surface 2212 of the fixed portion 221.

[0111] The support portion 222 is fixedly connected to the fixing portion 221. For example, the support portion 222 may be connected to an end of the fixing portion 221 away from the base 21. The support portion 222 may extend to the side 214 of the base 21 through the side 2213 of the fixing portion 221, and may be spaced apart from the side 2213 of the fixing portion 221 and the side 214 of the base 21.

[0112] Exemplarily, the support portion 222 may have a top end 2221 and a bottom end 2222. The top end 2221 of the support portion 222 is fixedly connected to the fixed portion 221, and the bottom end 2222 of the support portion 222 surrounds the base 21 and is spaced apart from the base 21. It is understandable that in the embodiment of the present application, a partial structure of the support portion 222 may surround the fixed portion 221, and is opposite to and spaced apart from the fixed portion 221, that is, an air gap may exist between the partial structure of the support portion 222 and the fixed portion 221. A partial structure of the support portion 222 may surround the base 21, and is spaced apart from the base 21, that is, an air gap may exist between the partial structure of the support portion 222 and the base 21. Exemplarily, the support portion 222 of the support member 22, the fixed portion 221 of the support member 22, and the base 21 may jointly enclose a buffer space 223.

[0113] In the embodiment of the present application, the shape of the support member 22 is set so that the earplug 20 can have a buffer space 223. In this way, when the user wears the earphone 100, the support portion 222 of the support member 22 is easily deformed under the pressure of the user's ear canal, so that the earplug 20 and the earphone 100 are not likely to cause pressure on the user's ear canal, which is conducive to improving the wearing comfort of the earplug 20 and the earphone 100.

[0114] Exemplarily, the support member 22 may have a second through hole 220. The second through hole 220 penetrates the support member 22 in a direction from the top of the earplug 20 to the bottom of the earplug 20. The second through hole 220 of the support member 22 may be connected to the first through hole 210 of the base 21. Exemplarily, the second through hole 220 may be provided in the fixing portion 221. For example, the first through hole 210 may penetrate the top surface 2211 and the bottom surface 2212 of the base 21. The side surface 2213 of the fixing portion 221 of the support member 22 surrounds the second through hole 220 of the support member 22.

[0115] Please refer to Figure 5 , Fig. 8A and Figure 8B , Fig. 8A yes Figure 3 The earplug 20 shown is a partial cross-sectional structural diagram cut along AA. Figure 8B yes Figure 3 The earplug 20 shown is a partial cross-sectional front view taken along line AA.

[0116] In some embodiments, the contact member 23, the fixing portion 221 of the support member 22, and the base 21 are arranged in sequence from the top of the earplug 20 to the bottom of the earplug 20. The fixing portion 221 of the support member 22 can be connected between the base 21 and the contact member 23. For example, the top surface 2211 of the fixing portion 221 can be connected to the contact member 23. In this way, the fixing portion 221 of the support member 22 can support the contact member 23.

[0117] Exemplarily, the contact member 23 may include a first portion 231 and a second portion 232. The second portion 232 is fixedly connected to the first portion 231. The first portion 231 and the second portion 232 are arranged in sequence from the top of the earplug 20 to the bottom of the earplug 20. Fig. 8A and Figure 8B In the figure, a wider dotted line is used to exemplarily distinguish between the first portion 231 and the second portion 232 of the contact 23.

[0118] Exemplarily, the first portion 231 may be located on the top side of the support member 22. The first portion 231 is fixedly connected to the fixing portion 221 and the supporting portion 222 of the support member 22. The second portion 232 may be fixed to the outer surface of the supporting portion 222, that is, fixed to the side surface of the supporting portion 222 facing away from the fixing portion 221 and the base 21. In this way, the supporting portion 222 of the support member 22 may support the contact member 23. Exemplarily, the second portion 232 may be arranged around the fixing portion 221 of the support member 22 and the base 21. Among them, Fig. 8A and Figure 8B A narrower dotted line is used to exemplarily distinguish between the fixing portion 221 and the supporting portion 222 of the supporting member 22 .

[0119] Exemplarily, the contact member 23 may have a third through hole 230. In the direction from the top of the earplug 20 to the bottom of the earplug 20, the third through hole 230 may penetrate the contact member 23 and communicate with the first through hole 210 of the base 21. For example, the third through hole 230 of the contact member 23 may penetrate the first portion 231 of the contact member 23.

[0120] It can be understood that in the embodiment of the present application, the first through hole 210 of the base 21, the second through hole 220 of the support member 22, and the third through hole 230 of the contact member 23 are interconnected and together form the sound outlet channel 201 of the earplug 20. That is, the sound outlet channel 201 of the earplug 20 may include the first through hole 210 of the base 21, the second through hole 220 of the support member 22, and the third through hole 230 of the contact member 23.

[0121] In some embodiments, the base 21, the support member 22 and the contact member 23 are all flexible members. In the embodiment of the present application, the base 21, the support member 22 and the contact member 23 are all flexible members. When the user wears the earphone 100, the earplug 20 can enter the ear canal of the user, and the earplug 20 can be deformed by being squeezed by the ear canal of the user, so that the earplug 20 can adapt to the shape of the ear canal of the user.

[0122] The hardness of the base 21 is greater than the hardness of the support 22. In this way, the base 21 of the earplug 20 can have a greater hardness. When the earplug 20 is installed in the earphone body 10, the base 21 of the earplug 20 and the mounting portion 112 of the ear shell 11 are stably engaged, and the earplug 20 is not easy to fall off from the earphone body 10.

[0123] Among them, the hardness of the support member 22 is greater than the hardness of the contact member 23. It can be understood that in this embodiment, the hardness of the base 21 and the support member 22 is greater than the hardness of the contact member 23. On the one hand, due to the small hardness of the contact member 23, the contact member 23 is more likely to be deformed after being squeezed by the user's ear canal, so that the contact member 23 can better adapt to the shape of the user's ear canal; and after the contact member 23 is squeezed by the user's ear canal, the reaction force on the user's ear canal is small, and the user's ear canal will not be compressed, which is conducive to improving the user's wearing comfort. On the other hand, the hardness of the support member 22 is large, and the support member 22 is less deformed after being squeezed by the user's ear canal. The support member 22 has a certain supporting effect on the contact member 23, which can make the contact member 23 more fit the user's ear canal, so that the earplug 20 and the earphone 100 are not easy to fall off from the user's ear canal, and the earplug 20 and the earphone 100 have good wearing stability. It can be understood that the earplug 20 and the earphone 100 provided in the embodiment of the present application can take into account good wearing comfort and wearing stability.

[0124] Exemplarily, the hardness of the base 21 can be in the range of 60 to 80HA. For example, 60HA, 70HA, 80HA, etc. In this way, the hardness of the base 21 is relatively appropriate. On the one hand, the base 21 can have a certain deformation ability, which is convenient for snapping with the mounting portion 112 of the ear shell 11; on the other hand, the base 21 can have a certain hardness, and the stability of the snapping between the base 21 and the mounting portion 112 of the ear shell 11 is good, so that the earplug 20 is not easy to fall off the earphone body 10. Among them, "HA" represents Shore A hardness, which refers to the hardness value of the material measured by using a Shore A durometer, and the unit is degree. For example, if the hardness value of the material tested using a Shore A durometer is 70 degrees, it is marked as: 70HA.

[0125] Exemplarily, the hardness of the support member 22 can be in the range of 30 to 40HA. For example, 30HA, 35HA, 40HA, etc. In this way, the hardness of the support member 22 is relatively appropriate. On the one hand, the support member 22 can support the contact member 23, so that the contact member 23 fits the user's ear canal more closely, so that the earplug 20 can have better wearing stability; on the other hand, after the support member 22 is squeezed by the user's ear canal, the reaction force on the user's ear canal is small, and it will not cause strong pressure on the user's ear canal, which is conducive to improving the wearing comfort of the earplug 20.

[0126] For example, the hardness of the contact member 23 is less than 30HA. In this way, the contact member 23 is relatively soft. The contact member 23 is easily deformed after being squeezed by the user's ear canal, and will not cause pressure on the user's ear canal, so that the earplug 20 can have better wearing comfort.

[0127] In some embodiments, the material of the support member 22 may be a noise reduction material. The noise reduction material may reduce the noise decibel by absorbing, refracting and weakening sound waves. For example, the material of the support member 22 may be soft silicone, polyurethane (PU), etc. In this way, the support member 22 may meet its hardness requirements and have a good noise reduction effect. It is understandable that the material of the contact member 23 is usually sponge, and since the sponge is a loose and porous structure, it is easy to cause sound leakage in the earplug 20 and the earphone 100. The earplug 20 and the earphone 100 have poor noise isolation capabilities. In the embodiment of the present application, the support member 22 is made of noise reduction material, so that when the user wears the earphone 100, the support member 22 can better isolate the noise, which is conducive to improving the noise reduction effect of the earplug 20 and the earphone 100, that is, improving the passive isolation performance of the earplug 20 and the earphone 100. In this way, the earplug 20 and the earphone 100 can take into account good wearing comfort, wearing stability and noise reduction effect.

[0128] Exemplarily, the material of the contact member 23 may be sponge, such as foam sponge. The contact member 23 made of sponge can better adapt to the shape of the user's ear canal, so that the earplug 20 and the earphone 100 can have better wearing comfort.

[0129] For example, the base 21 may be made of hard silicone. Thus, the manufacturing process of the base 21 is relatively simple and the cost is relatively low.

[0130] In some embodiments, the base 21, the support member 22 and the contact member 23 are integrally formed structural members. That is, the earplug 20 can be an integrally formed structural member. In this way, the base 21, the support member 22 and the contact member 23 are tightly connected, and the sealing performance of the earplug 20 is good, and sound leakage is not likely to occur. The earplug 20 and the earphone 100 have a good sound insulation effect.

[0131] In some embodiments, the support member 22 can be fixed to the base 21 by an injection molding process. When the contact member 23 is a sponge, the contact member 23 can be fixed to the outer surface of the support member 22 by a foaming process. It can be understood that the base 21, the support member 22 and the contact member 23 form an integral structure by the above process, and the support member 22 is sealed and connected to the base 21 and the contact member 23.

[0132] Exemplarily, the fixing portion 221 of the support member 22 can be sealed and connected to the base 21. For example, the bottom surface 2212 of the fixing portion 221 of the support member 22 can be fitted and sealed to the first surface 211 of the fixing seat. Exemplarily, the fixing portion 221 of the support member 22 and the supporting portion 222 of the support member 22 are both sealed and connected to the contact member 23. For example, the bottom surface 2212 of the fixing portion 221 of the support member 22 and the outer surface of the supporting portion 222 of the support member 22 can be fitted and sealed to the contact member 23.

[0133] See also Figure 8B In some embodiments, in a direction perpendicular to the central axis A1-A1 of the first through hole 210, the distance between the central axis A1-A1 of the first through hole 210 and the outer edge of the first surface 211 of the base 21 is S7, and the distance between the central axis A1-A1 of the first through hole 210 and the outer edge of the second surface 212 of the base 21 is S8. <S8。

[0134] It can be understood that, when cut along the direction parallel to the top of the earplug 20 toward the bottom of the earplug 20, the cross section of the base 21 can be roughly a "small top, large bottom" structure. The lateral dimension of the bottom of the base 21 (i.e., the dimension in the direction perpendicular to the central axis A1-A1 of the first through hole 210) can be larger, so that the space of the first through hole 210 of the base 21 can be correspondingly increased, so that when the earplug 20 is installed on the earphone body 10, more structures on the earphone body 10 can be accommodated in the first through hole 210 of the base 21. In this way, it is conducive to better utilization of the space inside the earphone body 10, thereby facilitating the miniaturization of the earphone 100.

[0135] In some embodiments, in a direction perpendicular to the central axis A1-A1 of the first through hole 210, the distance between the central axis A1-A1 of the first through hole 210 and the outer edge of the top surface 2211 of the fixing portion 221 of the support member 22 is S1, and the distance between the central axis A1-A1 of the first through hole 210 and the outer edge of the bottom surface 2212 of the fixing portion 221 of the support member 22 is S2. <S2。

[0136] It can be understood that, when cut along the direction parallel to the top of the earplug 20 to the bottom of the earplug 20, the cross section of the fixing portion 221 of the support member 22 can be roughly a trapezoidal structure with a "small top and large bottom". In this way, the area of ​​the bottom surface 2212 of the fixing portion 221 can be relatively large. Since the bottom surface 2212 of the fixing portion 221 is connected to the first surface 211 of the base 21, the area of ​​the first surface 211 of the base 21 can also be increased accordingly. On the one hand, the connection area between the fixing portion 221 of the support member 22 and the base 21 is relatively large, and the connection firmness between the fixing portion 221 of the support member 22 and the base 21 is relatively good; on the other hand, the lateral dimension of the base 21 (that is, the dimension in the direction perpendicular to the central axis A1-A1 of the first through hole 210) can also be increased accordingly, so that the space of the first through hole 210 of the base 21 can be increased accordingly, so that when the earplug 20 is installed on the earphone body 10, more structures on the earphone body 10 can be accommodated in the first through hole 210 of the base 21.

[0137] In some embodiments, in the direction perpendicular to the central axis A1-A1 of the first through hole 210, the thickness of the fixing portion 221 is greater than the thickness of the supporting portion 222. On the one hand, in the direction perpendicular to the central axis A1-A1 of the first through hole 210, the thickness of the fixing portion 221 is larger, so that the connection area between the fixing portion 221 and the contact member 23 is larger, which can not only improve the connection firmness between the fixing portion 221 and the contact member 23, but also help to improve the sealing performance between the fixing portion 221 and the contact member 23, and reduce the risk of sound leakage between the earplug 20 and the earphone 100. On the other hand, in the direction perpendicular to the central axis A1-A1 of the first through hole 210, the thickness of the supporting portion 222 is smaller, and the supporting portion 222 is more likely to deform after being squeezed. When the user wears the earphone 100, the user's ear canal squeezes the supporting portion 222, and the reaction force of the supporting portion 222 on the user's ear canal is smaller, so that the supporting portion 222 and the earplug 20 are not likely to cause pressure on the user's ear canal, which is conducive to improving the wearing comfort of the earplug 20 and the earphone 100.

[0138] Exemplarily, in the direction perpendicular to the central axis A1-A1 of the first through hole 210, the width of the top surface 2211 of the fixing portion 221 of the support member 22 is in the range of 0.8 mm to 1.0 mm. In this way, in the direction perpendicular to the central axis A1-A1 of the first through hole 210, the thickness of the fixing portion 221 of the support member 22 is more appropriate, and the connection firmness and sealing between the fixing portion 221 and the contact member 23 are better.

[0139] Exemplarily, in the direction perpendicular to the central axis A1-A1 of the first through hole 210, the width of the support portion 222 of the support member 22 is in the range of 0.3mm to 0.4mm. In this way, in the direction perpendicular to the central axis A1-A1 of the first through hole 210, the width of the support portion 222 of the support member 22 is more appropriate, and the support member 22 is not easy to cause pressure on the user's ear canal, which can meet the wearing comfort requirements. It can be understood that in the direction perpendicular to the central axis A1-A1 of the first through hole 210, the width of the support portion 222 of the support member 22 at various locations is in the range of 0.3mm to 0.4mm, and the width at various locations may be the same or different. This embodiment does not strictly limit this.

[0140] In some embodiments, in a direction perpendicular to the central axis A1-A1 of the first through hole 210, the distance between the central axis A1-A1 of the first through hole 210 and the outer edge of the top end surface 2223 of the support portion 222 (i.e., the end surface of the top end 2221) is S5, and the distance between the central axis A1-A1 of the first through hole 210 and the outer edge of the bottom end surface 2224 of the support portion 222 (i.e., the end surface of the bottom end 2222) is S6. <S6。

[0141] It can be understood that the support portion 222 of the support member 22 can be roughly umbrella-shaped. From the top 2221 of the support portion 222 to the bottom 2222 of the support portion 222, the support portion 222 can gradually move away from the central axis A1-A1 of the first through hole 210. In this way, when the user wears the earphone 100, the bottom 2222 of the support portion 222 can fit the ear canal of the user more closely, thereby reducing the risk of sound leakage of the earplug 20 and the earphone 100, and the sound insulation effect of the earplug 20 and the earphone 100 is better.

[0142] In some embodiments, in a direction perpendicular to the central axis A1-A1 of the first through hole 210, the distance between the outer edge of the top surface 2211 of the fixing portion 221 and the outer edge of the contact member 23 is S3, and the distance between the outer edge of the bottom end surface 2224 of the supporting portion 222 and the outer edge of the contact member 23 is S4. <S4。

[0143] It is understandable that the material of the contact member 23 is usually sponge, and since the sponge has a loose and porous structure, it is easy to cause sound leakage from the earplug 20 and the earphone 100. The present application reduces the thickness of the bottom of the contact member 23 to reduce the proportion of the porous structure on the bottom of the earplug 20, so that when the user wears the earphone 100, it is not easy to leak sound at the bottom of the earplug 20. The earplug 20 and the earphone 100 have a good sound insulation effect.

[0144] Exemplarily, the distance S4 between the outer edge of the bottom end surface 2224 of the support portion 222 and the outer edge of the contact member 23 is in the range of 0.85 mm to 1.2 mm. In this way, the thickness of the bottom of the contact member 23 is relatively appropriate, and the contact member 23 is not likely to cause pressure on the user's ear canal, which can meet the wearing comfort requirements, and is conducive to reducing the risk of sound leakage of the earplug 20 and the earphone 100, and the earplug 20 and the earphone 100 have a better sound insulation effect.

[0145] The above mainly describes the structure and setting method of the earplug 20 of the earphone 100. The earphone body 10 of the earphone 100 will be introduced below in conjunction with relevant drawings.

[0146] Please refer to Fig. 9 and Fig.10 , Fig. 9 yes Figure 2 The structure diagram of the earphone body 10 in some embodiments is shown in FIG. Fig.10 yes Fig. 9 The structure diagram of the part of the earphone body 10 shown in some embodiments. Fig.10 FIG. 1 mainly shows a schematic structural diagram of a part of the ear shell 11 of the earphone body 10 in some embodiments.

[0147] In some embodiments, the earphone body 10 may further include an ear handle 12 (also referred to as an ear rod). The ear handle 12 may be fixed to the ear shell 11. For example, the ear handle 12 may be fixed to a side of the ear shell 11 that is away from the mounting portion 112, or the ear handle 12 may be fixed to a side of the ear shell 11.

[0148] Exemplarily, the ear handle 12 may include a handle portion 121 and a connecting portion 122. The connecting portion 122 may be fixedly connected to the ear shell 11 by means of snapping, bonding, etc. The handle portion 121 is located on the side of the connecting portion 122 facing away from the ear shell 11, and is fixedly connected to the connecting portion 122. It is understandable that the connecting portion 122 and the handle portion 121 may be an integrally formed structural member to facilitate the processing of the ear handle 12. In other embodiments, the connecting portion 122 and the handle portion 121 may also be formed as a whole by means of bonding or snapping.

[0149] Exemplarily, the main body 111 of the ear shell 11 may be roughly a partial elliptical shell. The mounting portion 112 of the ear shell 11 may be annular. For example, the mounting portion 112 may be roughly runway-shaped. It is understandable that the mounting portion 112 may have a first straight line segment 112a and a second straight line segment 112b that are relatively arranged, and a first arc segment 112c and a second arc segment 112d that are relatively arranged. The first straight line segment 112a and the second straight line segment 112b are respectively connected between the first arc segment 112c and the second arc segment 112d. The first straight line segment 112a may be parallel to the second straight line segment 112b. The inner normal directions of the first arc segment 112c and the second arc segment 112d are opposite. Among them, Fig.10 The first straight line segment 112a, the second straight line segment 112b, the first arc segment 112c and the second arc segment 112d are schematically distinguished by dotted lines.

[0150] In the embodiment of the present application, compared with the annular mounting portion 112, the mounting portion 112 is configured to be runway-shaped in the embodiment of the present application, so that the space on the main body 111 can be better utilized, making the space inside the mounting portion 112 larger.

[0151] Exemplarily, the ear shell 11 may be provided with a clamping portion 113. The clamping portion 113 may be connected to and protrude from the outer peripheral side wall of the mounting portion 112. In some exemplary embodiments, the mounting portion 112 and the clamping portion 113 may be an integrally formed structure, thereby simplifying the process. In other embodiments, the mounting portion 112 and the clamping portion 113 may also be fixedly connected by bonding, clamping, etc. to form a whole.

[0152] Exemplarily, the number of the clamping portions 113 may be two, and the two clamping portions 113 may be located on two symmetrical sides of the mounting portion 112. For example, the two clamping portions 113 may be connected to the first arc segment 112c and the second arc segment 112d of the mounting portion 112, respectively.

[0153] In some embodiments, the main body 111 of the ear shell 11 may have a first sound outlet hole 1111, a second sound outlet hole 1112, and a third sound outlet hole 1113a that are arranged at intervals. The first sound outlet hole 1111 and the second sound outlet hole 1112 are both located on the inner side of the mounting portion 112. The first sound outlet hole 1111, the second sound outlet hole 1112, and the third sound outlet hole 1113a are all connected to the internal space of the main body 111 and the outside of the main body 111.

[0154] Exemplarily, the first sound outlet hole 1111 and the second sound outlet hole 1112 are arranged opposite to each other and spaced apart. For example, the first sound outlet hole 1111 and the second sound outlet hole 1112 may be located on opposite sides of the mounting portion 112. From the first arc segment 112c of the mounting portion 112 to the direction of the second arc segment 112d, the second sound outlet hole 1112 and the first sound outlet hole 1111 are arranged in sequence. That is, the arrangement direction of the second sound outlet hole 1112 and the first sound outlet hole 1111 may be parallel to the extension direction of the first straight line segment 112a.

[0155] In some embodiments, the main body 111 of the ear shell 11 may further have a fourth sound outlet hole 1113b. The fourth sound outlet hole 1113b may be located between the first sound outlet hole 1111 and the second sound outlet hole 1112, and may be spaced apart from the first sound outlet hole 1111 and the second sound outlet hole 1112. The fourth sound outlet hole 1113b may also be spaced apart from the third sound outlet hole. Exemplarily, the arrangement direction of the third sound outlet hole 1113a and the fourth sound outlet hole 1113b may be perpendicular to the extension direction of the first straight line segment 112a of the mounting portion 112.

[0156] It can be understood that the first sound outlet 1111, the second sound outlet 1112, the third sound outlet 1113a and the fourth sound outlet 1113b of the ear shell 11 are all part of the sound outlet of the earphone body 10. That is, the sound outlet of the earphone body 10 may include the first sound outlet 1111, the second sound outlet 1112, the third sound outlet 1113a and the fourth sound outlet 1113b. At this time, the sound outlet of the earphone body 10 may be located at the ear shell 11. The sound outlet of the earphone body 10 may connect the inside of the earphone body 10 with the outside of the earphone body 10. When the earplug 20 is fixed to the earphone body 10, the sound outlet of the earphone body 10 is connected to the first through hole 210 of the earplug 20. At this time, the sound emitted by the sound-emitting element inside the earphone body 10 can be transmitted through the sound outlet of the earphone body 10 and the sound outlet channel 201 of the earplug 20 to be received by the user.

[0157] In some embodiments, the main body 111 of the ear shell 11 may also have a first protrusion 1114 and a second protrusion 1115. The first protrusion 1114 and the second protrusion 1115 are both located on the inner side of the mounting portion 112. Exemplarily, the first protrusion 1114 may be roughly annular. The first protrusion 1114 may be arranged around the first sound outlet hole 1111. The first protrusion 1114 may be at least partially located between the second sound outlet hole 1112 and the first sound outlet hole 1111. In this way, the first protrusion 1114 may separate the first sound outlet hole 1111 from the second sound outlet hole 1112, the third sound outlet hole 1113a, and the fourth sound outlet hole 1113b.

[0158] Exemplarily, the second protrusion 1115 may be arc-shaped. The second protrusion 1115 partially surrounds the second sound outlet hole 1112. It is understandable that the second protrusion 1115 may surround a portion of the structure of the second sound outlet hole 1112, but not another portion of the structure of the second sound outlet hole 1112. In this way, the second protrusion 1115 can avoid other structural parts (e.g., dust screen) on the earphone 100.

[0159] Exemplarily, the second protrusion 1115 is at least partially located between the second sound outlet hole 1112 and the first sound outlet hole 1111. In this way, the second protrusion 1115 can separate the second sound outlet hole 1112 from the first sound outlet hole 1111 and the third sound outlet hole 1113a.

[0160] In some embodiments, the main body 111 of the ear shell 11 may further include a third protrusion 1116. The third protrusion 1116 may be located between the second protrusion 1115 and the first protrusion 1114, and connect the second protrusion 1115 and the first protrusion 1114. The third protrusion 1116 may enhance the overall structural strength of the ear shell 11. Fig.10 The first protrusion 1114 , the second protrusion 1115 , and the third protrusion 1116 are schematically distinguished by dotted lines.

[0161] The exemplary third protrusion 1116 may be located between the third sound outlet hole 1113a and the fourth sound outlet hole 1113b. That is, the third sound outlet hole 1113a and the fourth sound outlet hole 1113b may be located on both sides of the third protrusion 1116. In this way, the third protrusion 1116 may separate the third sound outlet hole 1113a from the fourth sound outlet hole 1113b.

[0162] In some other embodiments, the ear shell 11 may not have the fourth sound outlet hole 1113 b and / or the third protrusion 1116 .

[0163] See also Fig.10 and Fig.11 , Fig.11 yes Figure 1AThe illustrated structure is a schematic diagram of a partial cross-section of the earphone 100 taken along line BB in some embodiments.

[0164] In some embodiments, the base 21 of the earplug 20 can be sleeved on the mounting portion 112 of the ear shell 11. The mounting portion 112 of the ear shell 11 can be located in the first through hole 210 of the base 21. Exemplarily, at least a portion of the snap-fitting portion 113 can be located in the snap-fitting slot 215 of the base 21, so that the mounting portion 112 of the ear shell 11 can be snap-fitted with the base 21 of the earplug 20. In this embodiment, the number of the snap-fitting portion 113 and the snap-fitting slot 215 are two, respectively, and they are symmetrically arranged relative to the central axis A1-A1 of the first through hole 210. By arranging two symmetrical snap-fitting portions 113 to snap-fit ​​with two snap-fitting slots 215, respectively, the connection firmness between the ear shell 11 and the earplug 20 can be improved.

[0165] Exemplarily, part of the first sound outlet hole 1111 and the second sound outlet hole 1112 of the auricle 11 are respectively connected to the first through hole 210 of the earplug 20 , so that the first through hole 210 of the base 21 can be connected to the internal space of the auricle 11 .

[0166] Exemplarily, the sound outlet of the earphone body 10 (including the first sound outlet hole 1111, the second sound outlet hole 1112, the third sound outlet hole 1113a and the fourth sound outlet hole 1113b) are respectively connected to the first through hole 210 of the base 21 and the internal space of the ear shell 11, so that the internal space of the ear shell 11 can be connected to the first through hole 210 of the base 21 through the sound outlet of the earphone body 10, that is, the internal space of the ear shell 11 is connected to the sound outlet channel 201 of the earplug 20. In this way, the sound emitted by the acoustic element installed in the internal space of the ear shell 11 can be transmitted out of the earphone 100 through the sound outlet of the earphone body 10 and the sound outlet channel 201 of the earplug 20, and then transmitted to the ear canal of the user.

[0167] It can be understood that in the embodiment of the present application, by setting the shape of the base 21, the first through hole 210 of the base 21 has a larger space, so that the first sound hole 1111, the second sound hole 1112, the third sound hole 1113a and the fourth sound hole 1113b can all be at least partially located in the first through hole 210.

[0168] Please refer to Fig.12 and Fig.13 , Fig.12 yes Figure 2 The schematic diagram of the structure of the part of the earphone body 10 in other embodiments is shown. Fig.13 yes Fig.12 The partial structural exploded view of the ear shell 11 is shown. Fig.12 It mainly shows the structural schematic diagram of part of the structure of the ear shell 11 in other embodiments.

[0169] In some embodiments, the ear shell 11 may further include a dustproof net 114. The dustproof net 114 may be installed on the inner side of the mounting portion 112. The dustproof net 114 may cover the sound outlet of the earphone body 10 (including the first sound outlet 1111, the second sound outlet 1112, the third sound outlet 1113a, and the fourth sound outlet 1113b). In this way, the dustproof net 114 may prevent earwax, impurities, etc. outside the earphone body 10 from entering the interior of the earphone body 10 through the sound outlet of the earphone body 10, thereby affecting the normal operation of the earphone 100.

[0170] Exemplarily, the dustproof net 114 may include a top wall 1141 and a peripheral side wall 1142. The peripheral side wall 1142 of the dustproof net 114 is connected to the periphery of the top wall 1141 of the dustproof net 114. The top wall 1141 of the dustproof net 114 may be provided with a plurality of through holes 1143. The sound emitted by the acoustic element inside the earphone body 10 may be transmitted through the through holes 1143.

[0171] Exemplarily, the top wall 1141 of the dustproof net 114 can be located on the side of the main body 111 of the mounting portion 112 facing away from the ear shell 11, and cover the sound outlet of the earphone body 10 (including the first sound outlet 1111, the second sound outlet 1112, the third sound outlet 1113a and the fourth sound outlet 1113b).

[0172] Please refer to Fig.14 and Fig.15 , Fig.14 yes Fig.12 The partial cross-sectional structure diagram of the ear shell 11 cut along CC is shown. Fig.15 yes Fig.12 The shown structure is a partial cross-sectional view of the ear shell 11 cut along DD.

[0173] In some embodiments, the dustproof net 114 may be disposed around the first sound outlet hole 1111, the second sound outlet hole 1112, the third sound outlet hole 1113a, and the fourth sound outlet hole 1113b. Exemplarily, the peripheral side wall 1142 of the dustproof net 114 may be disposed around the first sound outlet hole 1111, the second sound outlet hole 1112, the third sound outlet hole 1113a, and the fourth sound outlet hole 1113b. The peripheral side wall 1142 of the dustproof net 114 may be disposed opposite to the second protrusion 1115 of the ear shell 11.

[0174] It can be understood that in the embodiment of the present application, by setting the second protrusion 1115 to be arc-shaped, the second protrusion 1115 can avoid the dustproof net 114, and the peripheral side wall 1142 of the dustproof net 114 and the second protrusion 1115 can jointly surround the second sound outlet hole 1112, thereby separating the second sound outlet hole 1112 from the first sound outlet hole 1111, the third sound outlet hole 1113a and the fourth sound outlet hole 1113b.

[0175] See also Fig.16 , Fig.16 yes Figure 1A The illustrated structure is a partial cross-sectional schematic diagram of the earphone 100 taken along line BB in some other embodiments.

[0176] In some embodiments, when the earplug 20 is fixed to the auricle 11, the dustproof net 114 may be located in the first through hole 210 of the earplug 20. The top wall 1141 of the dustproof net 114 may be located between the anti-scaling net 213 of the earplug 20 and the main body 111 of the auricle 11. The sound emitted by the acoustic element inside the earphone body 10 may be transmitted out of the earphone 100 through the dustproof net 114 and the anti-scaling net 213, and the dustproof net 114 and the anti-scaling net 213 may prevent earwax, impurities, etc. outside the earphone 100 from entering the interior of the earphone body 10.

[0177] See also Fig.17 , Fig.17 yes Figure 1A The earphone body 10 shown is a partial cross-sectional front view taken along line BB in some other embodiments.

[0178] In some embodiments, the earphone body 10 may further include a first acoustic element 131, a second acoustic element 132 and a third acoustic element 133. Among them, the first acoustic element 131 may be a microphone. The microphone is used to convert the sound signal into an electrical signal so that the earphone 100 can receive sound. Exemplarily, the first acoustic element 131 may be housed in the main body 111 of the ear shell 11. For example, the first acoustic element 131 may be located in the main body 111 near the first sound outlet 1111. A portion of the structure of the first acoustic element 131 may be located in the first sound outlet 1111. It can be understood that in the embodiment of the present application, sound can be transmitted between the first acoustic element 131 and the outside of the earphone 100 through the first sound outlet 1111. The first protrusion 1114 is arranged to surround the first sound hole 1111 so as to separate the first sound hole 1111 from the second sound hole 1112 , the third sound hole 1113 a and the fourth sound hole 1113 b , thereby reducing the risk of interference between the first acoustic element 131 and the second acoustic element 132 and the third acoustic element 133 .

[0179] In other embodiments, the first acoustic element 131 may also be located in the ear handle 12 of the earphone body 10 or in other locations in the ear shell 11 .

[0180] Exemplarily, the number of the first acoustic element 131 may be one or more. When there are more than one first acoustic element 131 , the first acoustic elements 131 may be arranged at different positions of the earphone body 10 .

[0181] Among them, the second acoustic element 132 can be a high-frequency speaker. The third acoustic element 133 can be a low-frequency speaker. The low-frequency speaker and the high-frequency speaker are used to convert electrical signals into sound signals, and the sound signals can be transmitted to the outside of the earphone 100 through the earplug 20 to achieve sound playback. The sound wave frequency mainly transmitted by the low-frequency speaker is in the range of 30Hz to 3kHz. The sound wave frequency mainly transmitted by the high-frequency speaker is in the range of 5KHz-16KHz. In an embodiment of the present application, the earphone 100 may include a high-frequency speaker and a low-frequency speaker, so that the sound quality of the earphone 100 can be improved.

[0182] Exemplarily, the second acoustic element 132 may be housed in the main body 111 of the ear shell 11. For example, the second acoustic element 132 may be located in the main body 111 near the second sound outlet 1112, and a portion of the second acoustic element 132 may be located in the second sound outlet 1112. Sound may propagate between the second acoustic element 132 and the outside of the earphone 100 through the second sound outlet 1112. For example, the sound emitted by the second acoustic element 132 may propagate to the outside of the earphone 100 through the second sound outlet 1112.

[0183] In some embodiments, the first acoustic element 131 and the second acoustic element 132 are arranged at intervals. Exemplarily, the arrangement direction of the first acoustic element 131 and the second acoustic element 132 may be perpendicular to the central axis A1-A1 of the first through hole 210 of the earplug 20. It is understood that in the embodiment of the present application, by setting the shape of the base 21 so that the first through hole 210 of the base 21 has a larger space, the arrangement direction of the first acoustic element 131 and the second acoustic element 132 may be perpendicular to the direction of the central axis A1-A1 of the first through hole 210. In this way, the first acoustic element 131 and the second acoustic element 132 can reasonably utilize the internal space of the ear shell 11, which is conducive to reducing the size of the ear shell 11, thereby facilitating the miniaturization of the earphone 100. In other embodiments, the second acoustic element 132 and the third acoustic element 133 may also be located in the ear handle 12 or other positions in the ear shell 11.

[0184] Exemplarily, the third acoustic element 133 can be accommodated in the main body 111 of the ear shell 11. The sound emitted by the third acoustic element 133 can be transmitted through the third sound outlet 1113a and the fourth sound outlet 1113b. It can be understood that the number of the third acoustic element 133 can be one or more, and the present application does not strictly limit this. When the number of the third acoustic element 133 is multiple, the multiple third acoustic elements 133 can be arranged at different positions in the ear shell 11.

[0185] In the embodiment of the present application, the second acoustic element 132 can be used to propagate high-frequency sound waves, and the third acoustic element 133 can be used to propagate low-frequency sound waves. The high-frequency sound waves can be transmitted through the second sound outlet 1112, and the low-frequency sound waves can be transmitted through the third sound outlet 1113a and the fourth sound outlet 1113b. Fig.14 ) partially surrounds the second sound outlet 1112 and the dustproof net 114 (see Fig.14 ) can surround the second sound outlet hole 1112 together with the second protrusion 1115, so that the second sound outlet hole 1112 is separated from the first sound outlet hole 1111, the third sound outlet hole 1113a and the fourth sound outlet hole 1113b, thereby reducing the risk of interference between the second acoustic element 132 and the first acoustic element 131 and the third acoustic element 133. In addition, the high-frequency sound waves passing through the second sound outlet hole 1112 can be separated from the low-frequency sound waves passing through the third sound outlet hole 1113a and the fourth sound outlet hole 1113b, reducing the risk of crosstalk between the high-frequency sound waves and the low-frequency sound waves.

[0186] In addition, by providing the third protrusion 1116 (see Fig.14 ), the third protrusion 1116 can separate the third sound hole 1113a from the fourth sound hole 1113b, so that the sound transmitted through the third sound hole 1113a and the sound transmitted through the fourth sound hole 1113b are not easily interfered.

[0187] See also Fig.18 , Fig.18 yes Figure 1A The illustrated earphone 100 is a partial cross-sectional front view of the structure taken along line BB in some other embodiments.

[0188] In some embodiments, when the earplug 20 is installed in the ear shell 11, the first acoustic element 131 and the second acoustic element 132 of the earphone body 10 are both partially located in the first through hole 210 of the base 21. It can be understood that in the embodiment of the present application, the first acoustic element 131 and the second acoustic element 132 can be arranged close to the earplug 20. In this way, when the user wears the earphone 100, the first acoustic element 131 and the second acoustic element 132 can be closer to the user's ear canal, and the sound emitted by the second acoustic element 132 can be better transmitted to the user's ear canal, thereby facilitating the improvement of the sound effect of the earphone 100.

[0189] See also Fig.19 , Fig.19 yes Figure 1A The earphone 100 is shown in side view in some other embodiments.

[0190] In some embodiments, the earphone body 10 may further include a detection component 14. The detection component 14 may be disposed on the ear shell 11. The detection component 14 may include an infrared sensor, a capacitive sensor, etc., for detecting whether the earphone 100 is worn by the user and whether it is taken off.

[0191] Exemplarily, the earphone 100 may also have a tuning hole 15. The tuning hole 15 may be provided on the ear handle 12 and connect the inside and outside of the ear handle 12. The tuning hole 15 allows air to circulate inside and outside the earphone 100, which is beneficial to improving the sound quality of the earphone 100. In some examples, a tuning net, tuning cotton, etc. may be bonded inside the tuning hole 15.

[0192] In some embodiments, the earphone body 10 may further include a power supply 16 (i.e., a battery). The power supply 16 may be housed in the ear handle 12, and the power supply 16 is used to power the earphone 100. When the earphone 100 is a wireless earphone 100, the earphone 100 may be applied to an earphone 100 assembly. The earphone 100 assembly may include an earphone 100 box, and the earphone 100 can be detachably stored in the earphone 100 box. Exemplarily, the earphone 100 may also be provided with a charging contact 17, and the charging contact 17 may be provided at one end of the ear handle 12 away from the ear shell 11. When the earphone 100 is installed in the earphone 100 box of the earphone 100 assembly, the earphone 100 box can charge the earphone 100 through the charging contact 17.

[0193] Exemplarily, the earphone body 10 may further include a circuit board 181 and a micro controller unit 182 (MCU). The circuit board 181 and the micro controller unit 182 may be accommodated in the ear shell 11. The micro controller unit 182 may be fixed to the circuit board 181.

[0194] Exemplarily, the earphone body 10 may further include a button 19 (see Figure 1B ). The button 19 may be disposed on the ear handle 12. The button 19 may be connected to the microcontroller unit 182 in the earphone body 10 for communication. The user may adjust the volume of the earphone 100 or control the playback mode of the earphone 100 by pressing the button 19.

[0195] In some other embodiments, the earphone 100 may not include the ear handle 12, and the main components of the earphone 100 are accommodated in the ear shell 11, or partially accommodated in the ear shell 11 and partially accommodated in other parts of the earphone 100. The embodiment of the present application does not strictly limit the specific structure of the earphone 100 and the position arrangement of the components.

[0196] It is understandable that the above embodiment mainly introduces the earplug 20 applied to the earphone 100, which can make the earphone 100 take into account wearing comfort, wearing stability and good sound insulation effect. The earplug 20 of the above embodiment can also be applied to other electronic devices other than the earphone 100 that need to take into account wearing comfort, wearing stability and good sound insulation effect.

[0197] It is understood that all the above drawings are exemplary illustrations of the present application and do not represent the actual size of the product. Moreover, the size ratio relationship between the components in the drawings is not intended to limit the actual product of the present application.
