Description

Technical Field

[0001] This application relates to the technical field of electronic devices, and in particular to headphones. Background Technology

[0002] With the increasing popularity of electronic devices, they have become indispensable social and entertainment tools in people's daily lives, and people's demands for electronic devices are also getting higher and higher. Electronic devices such as headphones and smart glasses are also widely used in people's daily lives. They can be used in conjunction with terminal devices such as mobile phones and computers to provide users with an auditory feast.

[0003] Modern headphones typically include touch circuitry or modules to detect whether they are being worn in the ear. However, the current headphone wear detection function is not very sensitive. Users often accidentally touch the headphones when removing or touching them, causing the headphones to misjudge the wear and affecting the user's experience. Summary of the Invention

[0004] To solve the above-mentioned technical problems, one technical solution adopted in this application is to provide an earphone, which includes an ear hook and a sound-emitting part connected to each other. In the wearing state, the ear hook is hung between the user's auricle and head, and the sound-emitting part is located on the front side of the auricle. The sound-emitting part includes a core housing and a first capacitor plate. The core housing has a connecting end connected to the ear hook and a free end away from the connecting end. At least a portion of the free end extends into the concha cavity or abuts against the auricle. The first capacitor plate is disposed inside the core housing and is at least partially located at the free end. The first capacitor plate is used to detect whether the earphone is being worn. The core housing has a length direction, a width direction and a thickness direction that are orthogonal to each other. The thickness direction is the direction in which the core housing faces or away from the auricle in the wearing state, and the length direction is the direction in which the core housing is close to or away from the back of the head in the wearing state. The first capacitor plate forms a first projection in a first reference plane perpendicular to the thickness direction. The first projection is located in a 5-equal region along the length direction of the core housing closest to the free end.

[0005] In some embodiments, the first projection is located in a 7-division area of ​​the movement housing closest to the free end along the length direction.

[0006] In some embodiments, when worn, at least a portion of the free end abuts against the helix or antihelix of the auricle.

[0007] In some embodiments, the first capacitor plate has a maximum distance from the outermost end of the free end along the length direction, and the ratio of the maximum distance to the overall length of the movement housing along the length direction is less than or equal to 0.2, wherein the overall length is the distance from the free end to the connection end of the movement housing.

[0008] In some embodiments, the mechanism housing includes a first sidewall and a second sidewall spaced apart along the thickness direction. The first sidewall is closer to the auricle than the second sidewall when worn. The first capacitor plate includes a first main body, a second main body, and a connecting portion. The second main body is spaced apart from the first main body along the thickness direction and is closer to the first sidewall. The connecting portion connects the first main body and the second main body and is bent such that the first main body and the second main body are not coplanar.

[0009] In some embodiments, the first capacitor plate forms a second projection in a second reference plane perpendicular to the length direction. The first projection includes a first sub-projection area formed by the first main body and a second sub-projection area formed by the second main body. The second projection includes a third sub-projection area formed by the first main body and a fourth sub-projection area formed by the second main body. The area of ​​the first sub-projection area is smaller than the area of ​​the third sub-projection area, and the area of ​​the second sub-projection area is smaller than the area of ​​the fourth sub-projection area.

[0010] In some embodiments, an annular flange is provided on the side wall of the first sidewall near the first capacitor plate. The earphone further includes a speaker and a sound cavity support disposed in the core housing. The annular flange cooperates with the speaker to form an acoustic front cavity, and the sound cavity support cooperates with the speaker to form an acoustic rear cavity. The first main body is fixed to the outer peripheral surface of the sound cavity support, and the second main body is fixed to the outer peripheral surface of the annular flange.

[0011] In some embodiments, the first main body includes at least two first sub-main bodies that are circumferentially bent and connected along the acoustic cavity support, and / or the second main body includes at least two second sub-main bodies that are circumferentially bent and connected along an annular flange.

[0012] In some embodiments, when the first reference plane is translated along the thickness direction, the first reference plane and the first main body form a first intersection line, and the length of the first intersection line increases along the direction from the second sidewall toward the first sidewall.

[0013] In some embodiments, when the first reference plane is translated along the thickness direction, the first reference plane and the second main body form a second intersection line, and the minimum length of the second intersection line is not less than the minimum length of the first intersection line.

[0014] In some embodiments, the minimum length of the second intersection line is not less than the maximum length of the first intersection line.

[0015] In some embodiments, the earphone further includes a second capacitor plate disposed on the second sidewall. The second capacitor plate is used to generate a touch signal in response to the user's touch action. In the length direction, the distance between the first capacitor plate and the second capacitor plate is not less than 4 mm.

[0016] The beneficial effects of this application are as follows: A first capacitor plate is provided in the earphone's core housing. The core housing has a free end and a connecting end arranged along its length. The free end extends into the concha or abuts against the auricle. The first capacitor plate is located in a 5-part region along the length of the core housing closest to the free end. This allows the first capacitor plate to be closer to the wall of the concha or the auricle, enabling it to more accurately determine whether the free end extends into the concha or abuts the user's auricle. This minimizes the chance of accidental triggering when the user picks up the earphone, reducing the probability of accidental touches. Furthermore, the first capacitor plate can more accurately determine whether the earphone is being worn, thus improving the user's wearing experience. Attached Figure Description

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0031] The reference to "embodiment" in this application means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0032] The following is an exemplary description of the headphones in the example embodiment.

[0033] Combination Figure 1 The user's ear 100 may include an external auditory canal 101 and an auricle 102. The auricle 102 may include physiological parts such as the antihelix 1024, helix 1026, and antitragus 1027. The auricle 102 may form a concha 1021, a cymba concha 1022, a triangular fossa 1023, and a scaphoid fossa 1025. Although the external auditory canal 101 has a certain depth and extends to the tympanic membrane of the ear 100, for ease of description, unless otherwise specified, the external auditory canal 101 specifically refers to its entrance (i.e., ear canal) away from the tympanic membrane. In addition, the concha 1021, cymba concha 1022, and triangular fossa 1023 have a certain volume and depth, and the concha 1021 is directly connected to the external auditory canal 101, that is, the aforementioned ear canal can be simply regarded as being located at the bottom of the concha 1021.

[0034] Headphone 1 is an audio converter capable of receiving electrical signals from a media player or receiver and converting them into sound waves that can be heard by the user. In some embodiments, headphone 1 can be an open-back headphone, such as an ear-hook headphone, a behind-the-ear headphone, or a clip-on headphone.

[0035] like Figure 2 and Figure 3 As shown, the earphone 1 can be an ear-hook type earphone. In some embodiments, when worn, at least a portion of the earphone 1 can be inserted into the concha 1021 of the user to improve wearing stability. In some embodiments, at least a portion of the sound-emitting part 20 of the earphone 1 can cover the auricle 102 of the user's ear 100, such as the antihelix 1024, cymba concha 1022, or triangular fossa 1023, but does not block the external auditory canal 101 of the user's ear 100 or visually obstruct the external auditory canal 101 of the user's ear 100. In some embodiments, the sound-emitting part 20 of the earphone 1 can also abut against the position of the helix 1026. In some embodiments, the sound-emitting part 20 of the earphone 1 can also fit against or rest against the facial area in front of the user's ear, with the side of the sound-emitting part 20 facing the user's ear or the user's external auditory canal 101.

[0036] Furthermore, individual differences may exist among different users, resulting in variations in the shape, size, and other dimensions of the earpiece 100. To facilitate description and reduce (or even eliminate) these individual differences, a simulator containing a head and its (left and right) earpieces 100 can be manufactured based on ANSI:S3.36, S3.25 and IEC:60318-7 standards. Examples include GRAS 45BC KEMAR, HEAD Acoustics, B&K 4128 series, or B&K 5128 series, to represent the scenario of most users wearing headphones 1. Taking GRAS KEMAR as an example, the simulator for earpiece 100 can be any one of GRAS 45AC, GRAS45BC, GRAS45CC, or GRAS 43AG; taking HEAD Acoustics as an example, the simulator for earpiece 100 can be any one of HMS II.3, HMS II.3LN, or HMS II.3LN HEC. Therefore, in this application, descriptions such as "the user is wearing earphone 1," "earphone 1 is in a wearing state," and "in a wearing state" can refer to the earphone 1 being worn on the ear 100 of the aforementioned simulator. Of course, due to individual differences among users, the earphone 1 worn by different users may differ from the earphone 1 being worn on the ear 100 of the aforementioned simulator, but such differences should be tolerable.

[0037] It should be noted that in fields such as medicine and anatomy, three basic planes—the sagittal plane, the coronal plane, and the horizontal plane—and three basic axes—the sagittal axis, the coronal axis, and the vertical axis—can be defined for the human body or human simulator. The sagittal plane is a plane perpendicular to the ground along the anteroposterior direction of the body, dividing the human body or human simulator into left and right parts. The coronal plane is a plane perpendicular to the ground along the left and right direction of the body, dividing the human body or human simulator into anterior and posterior parts. The horizontal plane is a plane parallel to the ground along the vertical direction of the body, dividing the human body or human simulator into superior and inferior parts. Correspondingly, the sagittal axis is the axis along the anteroposterior direction of the body and perpendicular to the coronal plane; the coronal axis is the axis along the left and right direction of the body and perpendicular to the sagittal plane; and the vertical axis is the axis along the vertical direction of the body and perpendicular to the horizontal plane. Furthermore, the "front side of the ear" mentioned in this application is a concept relative to "back side of the ear." The former refers to the side of the ear away from the head, while the latter refers to the side of the ear facing the head. Both refer to the ear 100 of the user or simulator. Specifically, when viewing the ear 100 of the human body or human simulator along the coronal axis, it can be as follows... Figure 1 As shown.

[0038] As an example, combined Figure 2 as well as Figure 3 The earphone 1 may include ear hooks 10 and a sound-emitting part 20 connected to each other. In the wearing state, the ear hooks 10 can be positioned between the user's auricle 102 and head, meaning at least a portion of the ear hooks 10 of the earphone 1 can be located behind the ear 100, so that the earphone 1 is attached to the ear 100. The sound-emitting part 20 can be located in front of the auricle 102. The sound-emitting part 20 can be a sound playback device, used to convert electrical signals into sound signals (also referred to as "sound waves" or "sound signals") and transmit them to the wearer's ear 100.

[0039] In some embodiments, the ear hook 10 may contain a battery or a circuit board, or the ear hook 10 may contain both a battery and a circuit board. Of course, the ear hook 10 may also omit the battery and circuit board, and instead install the battery and circuit board into the sound-generating part 20.

[0040] In some embodiments, such as Figures 2 to 6 As shown, the sound-generating part 20 may include a mechanism housing 210 and a first capacitor plate 220.

[0041] The housing 210 may have a connecting end 211 connected to the ear hook 10 and a free end 212 away from the connecting end 211. At least a portion of the free end 212 may extend into the concha 1021 or abut against the user's auricle 102. A first capacitor plate 220 may be disposed inside the housing 210 and at least partially located at the free end 212 of the housing 210. The first capacitor plate 220 is used to detect whether the earphone 1 is being worn.

[0042] In some embodiments, when worn, at least a portion of the free end 212 can extend into the concha cavity 1021. The first capacitor plate 220 disposed at the free end 212 can detect whether the earphone 1 is in a wearing state by detecting whether the free end 212 is in contact with the inner wall of the concha cavity 1021 or by detecting whether the portion of the free end 212 that accommodates the first capacitor plate 220 is close to a certain threshold with the inner wall of the concha cavity 1021.

[0043] In other embodiments, when worn, at least a portion of the free end 212 may abut against the user's auricle 102, for example, at least a portion of the free end 212 may abut against the helix 1026 or the antihelix 1024 of the auricle 102. The first capacitor plate 220 disposed at the free end 212 can detect whether the earphone 1 is in a wearing state by detecting whether the free end 212 is in contact with the user's auricle 102 (e.g., the helix 1026 or the antihelix 1024), or by detecting whether the portion of the free end 212 that houses the first capacitor plate 220 is close to the user's auricle 102 (e.g., the helix 1026 or the antihelix 1024) to a certain threshold.

[0044] The certain threshold can refer to the shortest distance between the portion of the free end 212 that houses the first capacitor plate 220 and the inner wall of the concha 1021 or the user's auricle 102 (e.g., the helix 1026 or the antihelix 1024). As an example, the certain threshold can be between 0 mm and 1 mm, that is, when the distance between the first capacitor plate 220 and the inner wall of the concha 1021 or the user's auricle 102 (e.g., the helix 1026 or the antihelix 1024) is close to 1 mm or less, the first capacitor plate 220 in the free end 212 can detect that the earphone 1 is in a wearing state.

[0045] In some embodiments, a certain threshold can be 0mm to 0.5mm, 0mm to 0.7mm, or 0mm to 2mm. That is, when the distance between the part of the free end 212 that houses the first capacitor plate 220 and the inner wall of the concha cavity 1021 or the user's auricle 102 (e.g., helix 1026 or antihelix 1024) is less than or equal to 2mm, 0.7mm, or 0.5mm, the first capacitor plate 220 in the free end 212 can detect that the earphone 1 is in a wearing state.

[0046] In some embodiments, the first capacitor plate 220 can be a plate capacitor plate, which is a conversion element that can convert mechanical quantities such as changes in resistance or pressure when in contact with the human body into changes in capacitance, thereby determining whether the earphone 1 is being worn. In some embodiments, the first capacitor plate 220 can be a conversion element that can convert changes in the distance between the first capacitor plate 220 and the target (the inner wall of the concha 1021 or the user's auricle 102) into changes in capacitance, thereby determining whether the earphone 1 is being worn based on the changes in capacitance of the first capacitor plate 220.

[0047] In some embodiments, such as Figure 5 as well as Figure 6 As shown, the earphone 1 may include a main control circuit board 201, which may be disposed inside the mechanism housing 210. The first capacitor plate 220 may be electrically connected to the main control circuit board 201. The electrical signal generated by the first capacitor plate 220 may be transmitted to the main control circuit board 201, and the main control circuit board 201 may further regulate the earphone 1 according to the electrical signal of the first capacitor plate 220.

[0048] In some embodiments, such as Figure 6 As shown, the first capacitor plate 220 can be entirely located inside the housing 210. When the free end 212 of the housing 210 contacts or approaches the concha 1021 or the user's auricle 102, it triggers a change in the capacitance value of the first capacitor plate 220 inside the housing 210, thus allowing the first capacitor plate 220 to detect that the earphone 1 is being worn. This design protects the first capacitor plate 220 from friction damage by the housing 210, facilitates the formation of the housing 210, reduces manufacturing complexity, and lowers the possibility of false triggering of the first capacitor plate 220.

[0049] Of course, in other embodiments, the first capacitor plate 220 may be partially located inside the mechanism housing 210, and the other part may be located outside the mechanism housing 210, or the first capacitor plate 220 may be entirely located outside the mechanism housing 210. The first capacitor plate 220 exposed outside the mechanism housing 210 may be only covered by a flexible coating, so as to contact or approach the concha 1021 or the user's auricle 102 to detect whether the earphone 1 is being worn. This arrangement can improve the detection sensitivity of the first capacitor plate 220 and ensure the accuracy of wear detection.

[0050] In some embodiments, the movement housing 210 has a length direction, a width direction, and a thickness direction that are orthogonal to each other.

[0051] The length direction can be the spacing direction between the connecting end 211 and the free end 212. The spacing direction between the connecting end 211 and the free end 212 refers to the extension direction of the line connecting the connecting end 211 and the free end 212. In some embodiments, the connecting end 211 and the free end 212 can be irregular or regular arc-shaped, and the extension direction of the line connecting the connecting end 211 and the free end 212 can be defined by a straight line perpendicular to the parallel tangent plane of the two reference points furthest apart on the connecting end 211 and the free end 212. The length direction can also be defined as the direction in which the movement housing 210 approaches or moves away from the back of the head when worn. As an example, the length direction can be as follows: Figures 2 to 7 The direction indicated by the middle arrow X.

[0052] The width direction can be defined as the direction in which the movement housing 210 approaches or moves away from the top of the head when worn. As an example, the width direction can be as follows: Figures 2 to 7 The direction indicated by the middle arrow Y.

[0053] The thickness direction can be the direction in which the movement housing 210 faces or moves away from the auricle 102 when worn. As an example, the thickness direction can be as follows: Figures 2 to 7 The direction indicated by the middle arrow Z. The thickness direction Z can be substantially parallel to the vibration direction of the speaker assembly in the sound-generating section 20, where substantially parallel means the spatial angle between the two directions is less than 5°.

[0054] In some embodiments, such as Figure 7 As shown, the first capacitor plate 220 can form a first projection 221 in a first reference plane perpendicular to the thickness direction Z. The first projection 221 is located in a 5-part region of the movement housing 210 along the length direction X, closest to the free end 212. In other words, the movement housing 210 can be divided into 5 equal parts along the length direction X, and the first capacitor plate 220 is disposed in one 1 / 5 region of the movement housing 210 closest to the free end 212. This arrangement makes the first capacitor plate 220 closer to the free end 212, improving the accuracy of wear detection, and does not occupy too much space in the movement housing 210 along the length direction X.

[0055] If the first capacitor plate 220 extends excessively along the length direction X into the area between the free end 212 and the connecting end 211, especially near the middle of the housing 210, it is prone to false triggering of the wearing detection when the user picks up the earphone 1. For example, if the first capacitor plate 220 extends excessively along the length direction X into the middle area of ​​the housing 210, when the user pinches the area between the free end 212 and the connecting end 211 with their fingers to wear the earphone, it is easy to trigger the first capacitor plate 220, causing the first capacitor plate 220 to erroneously detect that the earphone 1 is in a wearing state, affecting the user's wearing experience.

[0056] Therefore, by placing the first capacitor plate 220 in the five-part region along the length X of the housing 210 closest to the free end 212, the user can avoid accidental triggering when picking up the earphone 1. This allows the first capacitor plate 220 to more accurately determine whether the free end 212 has entered the concha 1021 or is against the user's auricle 102, thus enabling the first capacitor plate 220 to more accurately determine whether the earphone 1 is being worn, thereby improving the user's wearing experience.

[0057] In some embodiments, the first projection 221 may be located in a seven-part region along the length X of the movement housing 210 closest to the free end 212. In other words, the movement housing 210 may be divided into seven equal parts along the length X, and the first capacitor plate 220 may be disposed in one-seventh of the movement housing 210 closest to the free end 212. This arrangement allows the detection area corresponding to the first capacitor plate 220 to be more concentrated at the free end 212, thereby further reducing the possibility of the user accidentally touching the first capacitor plate 220 when touching other parts of the non-free end 212. This results in more accurate detection by the first capacitor plate 220, thus improving the user's wearing experience.

[0058] In other embodiments, in order to further improve the detection accuracy of the first capacitor plate 220, the first projection 221 may also be located in the 8- or 9-division area of ​​the mechanism housing 210 along the length direction X closest to the free end 212.

[0059] In some embodiments, such as Figure 6 As shown, the first capacitor plate 220 can have a maximum distance from the outermost end of the free end 212 along the length direction X, and the ratio of the maximum distance to the overall length of the mechanism housing 210 along the length direction X is less than or equal to 0.2.

[0060] The overall length can be the farthest distance between the free end 212 and the connecting end 211 of the movement housing 210 along the length direction X, or the overall length can be the length of the straight line segment between the parallel tangent planes perpendicular to the two reference points that are furthest apart on the connecting end 211 and the free end 212. The outermost end of the free end 212 refers to the point in the free end 212 that is farthest from the connecting end 211 along the length direction X, or when the free end 212 is a regular arc shape, the outermost end of the free end 212 can refer to the midpoint of the projection of the arc-shaped free end onto a plane perpendicular to the thickness direction Z.

[0061] As an example, the outermost end of the free end 212 can be as follows: Figure 6 As shown at midpoint B, the maximum distance from the outermost end of the free end 212 along the length direction X of the first capacitor plate 220 can be as follows: Figure 6 As shown at mid-distance L1, the overall length of the movement housing 210 is as follows: Figure 6 The mid-distance L2 is shown, where L1:L2≤0.2.

[0062] As an example, the overall length L2 of the movement housing 210 can be between 25mm and 35mm, and the maximum distance L1 can be between 4mm and 7mm. For example, the overall length of the movement housing 210 can be 26mm, 28mm, or 30mm, and the maximum distance L1 can be 4mm, 5mm, or 6mm, etc. The ratio of the maximum distance L1 to the overall length L2 of the movement housing 210 along the length direction X can be 0.15, 0.17, or 0.2, etc.

[0063] If the ratio of the maximum distance to the overall length of the housing 210 along the length direction X is greater than 0.2, it indicates that the first capacitor plate 220 occupies a significant amount of space on the housing 210 along the length direction X. The detection area corresponding to the first capacitor plate 220 is spread out to the area between the free end 212 and the connecting end 211, increasing the likelihood of false triggering of the first capacitor plate 220 and reducing its detection accuracy and sensitivity. Conversely, setting the ratio of the maximum distance to the overall length of the housing 210 along the length direction X to less than or equal to 0.2 allows the detection area corresponding to the first capacitor plate 220 to be more concentrated at the free end 212, further reducing false triggering and improving its detection accuracy.

[0064] In some embodiments, such as Figure 5 as well as Figure 6 As shown, the movement housing 210 may include a first sidewall 213 and a second sidewall 214 spaced apart along the thickness direction Z. In the wearing state, the first sidewall 213 is closer to the auricle 102 than the second sidewall 214. The first capacitor plate 220 may include a first main body portion 222, a second main body portion 223, and a connecting portion 224. The second main body portion 223 may be spaced apart from the first main body portion 222 along the thickness direction Z, and the second main body portion 223 may be closer to the first sidewall 213. The connecting portion 224 connects the first main body portion 222 and the second main body portion 223, and may be bent such that the first main body portion 222 and the second main body portion 223 are not coplanar.

[0065] Specifically, since the first sidewall 213 is closer to the auricle 102 than the second sidewall 214 when worn, the second main body 223 is positioned closer to the first sidewall 213 to facilitate the first capacitor plate 220 in detecting whether the free end 212 is in contact with or close to the inner wall of the concha 1021 or the user's auricle 102, thereby making it easier to determine whether the earphone 1 is being worn.

[0066] Furthermore, under the connecting action of the connecting part 224, the first main body part 222 and the second main body part 223 are configured to be non-coplanar, which can increase the setting area of ​​the first capacitor plate 220 within the limited internal space of the core housing 210, thereby improving the detection accuracy and detection sensitivity of the earphone 1 in terms of wearing status.

[0067] In some embodiments, such as Figure 6 As shown, the first main body portion 222 and the second main body portion 223 can be arranged to adapt to the shape of the free end 212 of the movement housing 210, thus exhibiting a non-coplanar configuration. For example, the free end 212 can be arc-shaped or rounded rectangular, and the first main body portion 222 and the second main body portion 223 can be bent to correspond to the arc-shaped free end 212, so that the first main body portion 222 and the second main body portion 223 can be positioned as close as possible to the free end 212 of the movement housing 210, thereby improving the detection sensitivity and accuracy of the first main body portion 222 and the second main body portion 223.

[0068] In some embodiments, such as Figure 5 as well as Figure 6 As shown, an annular flange 2131 may be provided on the side wall of the first sidewall 213 near the first capacitor plate 220. The earphone 1 may further include a speaker 30 and a sound cavity support 40 disposed in the core housing 210. As an example, the speaker 30 may be an air-conducting speaker 30, and the sound cavity support 40 may support and fix the speaker 30 in the core housing 210.

[0069] The annular flange 2131 can cooperate with the speaker 30 to form an acoustic front cavity 301, and the acoustic cavity support 40 cooperates with the speaker 30 to form an acoustic rear cavity 302. The sound waves generated by the speaker 30 can propagate to the outside through the acoustic front cavity 301 and the sound outlet 215 on the housing 210. For example... Figure 5 As shown, a pressure relief hole 216 can also be provided on the housing 210 of the mechanism. The acoustic rear cavity 302 is connected to the outside through the pressure relief hole 216. This arrangement allows the air pushed by the rear side of the diaphragm 321 to flow from the acoustic rear cavity 302 to the outside of the housing 210 of the mechanism, thereby preventing the pressure buildup in the acoustic rear cavity 302 from affecting the sound quality of the speaker 30 assembly.

[0070] Specifically, the first main body 222 can be fixed to the outer peripheral surface of the acoustic cavity support 40, and the second main body 223 can be fixed to the outer peripheral surface of the annular flange 2131. By using the acoustic cavity support 40 and the annular flange 2131 to fix the first capacitor plate 220, not only can the structure supporting the first capacitor plate 220 be saved, but the acoustic cavity support 40 and the annular flange 2131 can also achieve functional reuse, thereby improving the space utilization rate inside the mechanism housing 210, thus reducing the size of the earphone 1, while also improving the structural compactness and stability inside the mechanism housing 210.

[0071] In some embodiments, such as Figure 5 , Figures 7 to 9 As shown, the first main body 222 may include at least two first sub-main bodies 2221 that are bent and connected along the circumference of the acoustic cavity support 40. This arrangement allows the overall shape of the first main body 222 to match the circumferential shape of the acoustic cavity support 40. On the one hand, it can improve the strength of the fit between the first main body 222 and the acoustic cavity support 40, so that the first main body 222 occupies less space in the core housing 210, thereby reducing the overall size of the earphone 1. On the other hand, it can further increase the area of ​​the first capacitor plate 220, increase the detection area of ​​the first capacitor plate 220, and improve the detection sensitivity of the first capacitor plate 220.

[0072] As an example, such as Figure 5 , Figures 7 to 9 As shown, there can be two first sub-body portions 2221, which can be spaced apart along the width direction Y. The two first sub-body portions 2221 can be bent circumferentially along the acoustic cavity support 40, and the relatively far ends of the two first sub-body portions 2221 can abut against the acoustic cavity support 40. This ensures the detection sensitivity of the first capacitor plate 220 while also reducing the processing difficulty of the first capacitor plate 220. In other embodiments, to further improve the detection sensitivity of the first capacitor plate 220, the number of first sub-body portions 2221 can be three, four, or five, etc. The more first sub-body portions 2221 there are, the better the fit with the acoustic cavity support 40, and the larger the area of ​​the first capacitor plate 220.

[0073] In some embodiments, the acoustic cavity support 40 may also be provided with a fixing mechanism (not shown) corresponding to at least two first sub-body parts 2221. The fixing mechanism fixes at least two first sub-body parts 2221 respectively, so that the connection between the first body part 222 and the acoustic cavity support 40 is more stable, thereby improving the structural stability of the mechanism housing 210.

[0074] In some embodiments, such as Figure 5 , Figures 7 to 9As shown, the second main body 223 may include at least two second sub-main bodies 2231 that are circumferentially bent and connected along the annular flange 2131.

[0075] This configuration allows the overall shape of the second main body 223 to match the shape of the annular flange 2131. On the one hand, it can improve the strength of the fit between the second main body 223 and the annular flange 2131, so that the second main body 223 occupies less space in the mechanism housing 210, thereby reducing the size of the mechanism housing 210. On the other hand, it can further increase the area of ​​the first capacitor plate 220, increase the detection area of ​​the first capacitor plate 220, and improve the detection sensitivity of the first capacitor plate 220.

[0076] As an example, such as Figure 5 , Figures 7 to 9 As shown, there can be two second sub-body portions 2231, which can be spaced apart along the width direction Y. The two second sub-body portions 2231 can be bent circumferentially along the annular flange 2131, and the relatively far ends of the two second sub-body portions 2231 can abut against the annular flange 2131. This ensures the detection sensitivity of the first capacitor plate 220 while also reducing the processing difficulty of the first capacitor plate 220. In other embodiments, to further improve the detection sensitivity of the first capacitor plate 220, the number of second sub-body portions 2231 can be three, four, or five, etc. The more second sub-body portions 2231 there are, the better the fit with the annular flange 2131, and the larger the area of ​​the first capacitor plate 220.

[0077] In some embodiments, the annular flange 2131 may be provided with a fixing mechanism (not shown) corresponding to at least two second sub-body portions 2231. The fixing mechanism fixes at least two second sub-body portions 2231 to make the connection between the second body portion 223 and the annular flange 2131 more stable, thereby improving the structural stability of the movement housing 210.

[0078] In some embodiments, such as Figure 9 As shown, the first capacitor plate 220 can form a second projection 225 in a second reference plane perpendicular to the length direction X.

[0079] like Figure 8 as well as Figure 9As shown, the first projection 221 may include a first sub-projection area 2211 formed by the first main body 222 and a second sub-projection area 2212 formed by the second main body 223. The second projection 225 may include a third sub-projection area 2251 formed by the first main body 222 and a fourth sub-projection area 2252 formed by the second main body 223. The area of ​​the first sub-projection area 2211 may be smaller than the area of ​​the third sub-projection area 2251, and the area of ​​the second sub-projection area 2212 may be smaller than the area of ​​the fourth sub-projection area 2252.

[0080] When worn, the free end 212 is closer to the auricle 102 on one side along the thickness direction Z. Therefore, by setting the area of ​​the first sub-projection area 2211 to be smaller than the area of ​​the third sub-projection area 2251, and the area of ​​the second sub-projection area 2212 to be smaller than the area of ​​the fourth sub-projection area 2252, the overall size of the first projection 221 is smaller than the overall size of the second projection 225. This allows the first capacitor plate 220 to have a larger area extending along the thickness direction Z and a smaller area extending along the length direction X. This facilitates the first capacitor plate 220 in detecting whether the free end 212 is in contact with or close to the auricle 102 or the inner wall of the concha 1021, thereby improving the detection sensitivity of the first capacitor plate 220, reducing false triggering, and improving the detection accuracy of the first capacitor plate 220.

[0081] In some embodiments, such as Figure 6 , Figure 8 and Figure 9 As shown, when the first reference plane is translated along the thickness direction Z, the first reference plane can form a first intersection line with the first main body 222. The length of the first intersection line can gradually increase along the direction from the second sidewall 214 toward the first sidewall 213.

[0082] As an example, when the first reference plane is translated to a certain position along the thickness direction Z, the first intersection line can be as follows: Figure 8 and Figure 9 The line segment LH is shown in the figure. The shape of the first intersection line corresponding to the shape of the first main body 222 can take many forms. If the first main body 222 is arc-shaped, then the first intersection line is also an arc segment. If the first main body 222 is bent, then the first intersection line can also be a series of bent segments.

[0083] Specifically, if the first main body portion 222 is configured such that the first intersection line gradually lengthens along the direction from the second side wall 214 toward the first side wall 213, it means that the first main body portion 222 gradually widens in the direction from the second side wall 214 toward the first side wall 213. That is, the closer the first main body portion 222 is to the first side wall 213, the longer the first intersection line and the wider the first main body portion 222.

[0084] When a user picks up the earphone 1, they typically use two fingers to pinch the housing 210 along the width Y direction. Since the first sidewall 213 is closer to the auricle 102 than the second sidewall 214 when worn, the user's fingers will be closer to the second sidewall 214. By arranging the first main body 222 such that the first intersection line gradually lengthens along the direction from the second sidewall 214 towards the first sidewall 213, the width of the first main body 222 closer to the second sidewall 214 is slightly narrower than the width closer to the first sidewall 213. This ensures that the first main body 222 maintains detection sensitivity while minimizing accidental touches when the user pinches the earphone 1, thereby improving the detection accuracy of the first capacitor plate 220.

[0085] In some embodiments, such as Figure 9 As shown, when the first reference plane is translated along the thickness direction Z, the first reference plane and the second main body 223 form a second intersection line, and the minimum length of the second intersection line is not less than the minimum length of the first intersection line. The second intersection line can take on various shapes corresponding to the shape of the second main body 223. If the second main body 223 is arc-shaped, the second intersection line is also an arc segment; if the second main body 223 is bent, the second intersection line can also be multiple bent segments.

[0086] As an example, the second intersection line can be as follows: Figure 9 As shown in line segment LF, the minimum length of the second intersection line can be as follows: Figure 9 As shown in the midpoint L3, the minimum length of the first intersection line can be as follows: Figure 9 As shown in the mid-range L4 diagram.

[0087] Specifically, since the second main body 223 is closer to the first sidewall 213 than the first main body 222, it is closer to the auricle 102 when worn, making it easier for the user to contact the first main body 222 when picking up the earphone 1. Setting the minimum length of the second intersection line to be no less than the minimum length of the first intersection line results in a narrower minimum length of the first intersection line closer to the second sidewall 214, meaning the overall size of the first main body 222 is smaller. This further reduces the chance of accidental contact when the user pinches the earphone 1. Simultaneously, a longer minimum length of the second intersection line indicates a larger overall size of the second main body 223, ensuring the overall size of the first capacitor plate 220 and thus guaranteeing its detection sensitivity.

[0088] In some embodiments, the minimum length of the second intersection line may not be less than the maximum length of the first intersection line.

[0089] As an example, the minimum length of the second intersection line can be as follows: Figure 9 As shown in distance L3, the maximum length of the first intersection line can be as follows: Figure 9 The midpoint distance L5 is shown. Where L3 is greater than L5.

[0090] This configuration allows the width of the second main body 223, which is closer to the first sidewall 213, to be greater than the width of the first main body 222 in the width direction Y. When worn, the second main body 223 will be closer to the auricle 102. Therefore, setting the second main body 223 to be wider allows the second main body 223 to have a larger area to realize the detection function, which is convenient for wearing detection and thus improves the detection sensitivity of the second main body 223.

[0091] In some embodiments, such as Figure 5 and Figure 10 As shown, the earphone 1 may further include a second capacitor plate 50 disposed on the second sidewall 214, which can be used to generate a touch signal in response to a user's touch action. As an example, the second capacitor plate 50 may be located on the side of the second sidewall 214 facing away from the inside of the housing 210.

[0092] The second capacitor plate 50 can be a surface-mount capacitor plate, a device that converts mechanical quantities such as changes in resistance or pressure when in contact with the human body into changes in capacitance, and can generate touch signals. These touch signals can be control signals such as song switching signals, volume control signals, and power on / off signals, allowing users to control the headphones 1 to perform functions such as song switching, volume control, or power on / off by touching the second capacitor plate 50.

[0093] In some embodiments, the distance between the first capacitor plate 220 and the second capacitor plate 50 in the length direction X is not less than 4 mm. This distance can refer to the distance between the side of the first capacitor plate 220 closest to the connection end 211 and the side of the second capacitor plate 50 closest to the free end 212 in the length direction X; that is, the minimum relative distance between the first capacitor plate 220 and the second capacitor plate 50.

[0094] As an example, the spacing between the first capacitor plate 220 and the second capacitor plate 50 can be as follows: Figure 10 The intermediate distance L6 is shown. For example, the distance L6 between the first capacitor plate 220 and the second capacitor plate 50 can be 4mm, 4.25mm, 5mm or 5.5mm, etc.

[0095] If the distance between the first capacitor plate 220 and the second capacitor plate 50 is less than 5mm, the user may accidentally touch the first capacitor plate 220 when touching the second capacitor plate 50, resulting in a false touch. Therefore, setting the distance between the first capacitor plate 220 and the second capacitor plate 50 to be no less than 5mm can reduce false touches, making the detection of the first capacitor plate 220 and the touch control of the second capacitor plate 50 more accurate, thereby improving the user experience.

[0096] In some embodiments, such as Figure 11 As shown, the earphone 1 may include an antenna 60, which may include a radiator 610 arranged in a ring and a feed point 620 disposed on the radiator 610. The feed point 620 may receive the feed current. The feed current may form a first transmission current and a second transmission current that are transmitted in opposite directions along the circumference of the radiator 610 on both sides of the feed point 620. The first transmission current and the second transmission current may converge in the radiator 610.

[0097] Feed point 620 refers to the input interface of the feed current input to the radiator 610. It can transmit the feed current inside the earphone 1 to the radiator 610, and can also efficiently convert the received electromagnetic wave signal into a radio frequency signal for transmission into the control circuit inside the earphone 1. The feed current refers to the modulated high-frequency current in the earphone 1, which can enter the radiator 610 for transmission through feed point 620. The radiator 610 can undergo changes in electric and magnetic fields under the action of the feed current, and the electric and magnetic fields interact to generate electromagnetic waves. The feed current can carry electrical signals representing the communication information of the earphone 1. The earphone 1 can generate corresponding electromagnetic waves by controlling the feed current, and then communicate with other electronic devices such as mobile phones or computers through the corresponding electromagnetic waves.

[0098] Specifically, by arranging the radiator 610 in a ring shape, and by forming a first transmission current and a second transmission current that travel in opposite directions along the circumference of the radiator 610 on both sides of the feed point 620, the feed current can be dispersed after entering the radiator 610. This dispersed current distribution reduces the strong points of the electric field in the radiator 610, thereby reducing the amount of radiation absorbed by human tissue and thus decreasing the strength of the electric field inside the human body. Furthermore, the arrangement of the first and second transmission currents being opposite in direction and converging within the radiator 610 allows the electric fields generated by the first and second transmission currents to partially cancel each other out, further reducing the electric field in the radiator 610 and consequently reducing the amount of radiation energy absorbed by the human tissue. In other words, the arrangement of forming a first transmission current and a second transmission current traveling in opposite directions on both sides of the feed point 620 and allowing the two currents to converge within the radiator 610 reduces the SAR value of the antenna 60 and decreases the impact of electromagnetic waves from the earphone 1 on the human body. The SAR value represents the electromagnetic power absorbed or consumed per unit mass of human tissue.

[0099] In some embodiments, the convergence region of the first transmission current and the second transmission current may coincide with the 1 / 4 target wavelength transmission path starting from the feed point 620.

[0100] As an example, the confluence region of the first transmission current and the second transmission current can be as follows: Figure 11 As shown in region C.

[0101] Specifically, after the first and second transmitted currents enter the radiator 610 from the feed point 620, they will cause changes in the electric and magnetic fields of the radiator 610, thereby generating electromagnetic waves. Since the feed point 620 is usually a point of strong current, but the target wavelength of the electromagnetic waves generated by the first and second transmitted currents originating from the feed point 620 is a current weakness point after traveling 1 / 4 of the path, setting the confluence region of the reverse-transmitting first and second transmitted currents to coincide with the 1 / 4 target wavelength transmission path allows the electric fields of the first and second transmitted currents to balance the current weakness at the 1 / 4 target wavelength transmission path. Furthermore, the opposite transmission directions of the first and second transmitted currents allow the electric fields in the confluence region to cancel each other out, thus reducing the overall SAR value.

[0102] In some embodiments, the radiator 610 may include an inner ring edge 611 and an outer ring edge 612, and the radiator 610 may have a hollow area 630 connected to the inner ring edge 611 and the outer ring edge 612. Having a hollow area 630 connected to the inner ring edge 611 and the outer ring edge 612 on the radiator 610 can reduce the width of the radiator 610, thereby extending the transmission path of the feed current, dispersing the current distribution, and further reducing the radiated energy in the radiator 610, thus reducing the SAR value, i.e., reducing the impact of electromagnetic waves from the earphone 1 on the human body. In some embodiments, to better adapt the antenna 60 to the shape of the housing 210 and simultaneously reduce the SAR value of the antenna 60, the hollow area 630 on the radiator 610 may be connected only to the inner ring edge 611 or only to the outer ring edge 612. For example, as... Figure 11 As shown, the radiator 610 may be provided with a hollow area 630 that is connected to the inner ring edge 611 and the outer ring edge 612 of the radiator 610.

[0103] In some embodiments, the cutout area 630 may include a first cutout area 631 connected to the inner ring edge 611 of the radiator 610 and a second cutout area 632 connected to the outer ring edge 612. For example... Figure 11 As shown, the first cutout area 631 and the second cutout area 632 can be alternately arranged along the circumference of the radiator 610. This arrangement not only extends the transmission path of the feed current and further disperses the current distribution to reduce the SAR value of the antenna 60, but also balances the stress distribution on the surface of the antenna 60, minimizing the risk of antenna breakage during processing or mounting.

[0104] In some embodiments, such as Figure 11 As shown, the ratio of the width of the hollow area 630 along the width direction of the radiator 610 to the width of the radiator 610 can be no greater than 1 / 2. For example, the ratio of the width of the hollow area 630 along the width direction of the radiator 610 to the width of the radiator 610 can be 2 / 5, 1 / 4, 1 / 3, or 1 / 2, etc. The width direction of the radiator 610 can refer to the direction perpendicular to the extension direction of the radiator 610, or the straight line direction containing the shortest line segment between the inner ring edge 611 and the outer ring edge 612 of the radiator 610.

[0105] As an example, the direction of extension of the radiator 610 at a certain point can be as follows: Figure 11 As shown in the center direction O, the width direction of the radiator 610 can be as follows: Figure 11 As shown in the center direction P, the width of the radiator 610 can be as follows: Figure 11 As shown in the figure, the width of the hollow area 630 along the width direction P of the radiating body 610 can be as follows: Figure 11 The width E is shown in the figure.

[0106] If the ratio of the width of the cutout area 630 along the width direction of the radiator 610 to the width of the radiator 610 is set to be greater than 1 / 2, the radiating aperture of the antenna 60 will decrease, and the bandwidth will also narrow, affecting the radiated communication of the antenna 60. Therefore, setting the ratio of the width of the cutout area 630 along the width direction of the radiator 610 to the width of the radiator 610 to be no greater than 1 / 2 can extend the transmission path of the feed current, reduce the SAR value, and at the same time ensure the radiating aperture of the antenna 60, minimizing the impact on the radiation bandwidth.

[0107] In some embodiments, the radiator 610 may include a hollowed-out segment 613 and a strip segment 614 connected to each other circumferentially. The degree of bending of the strip segment 614 may be greater than that of the hollowed-out segment 613. A hollowed-out area 630 may be provided on the hollowed-out segment 613, while the strip segment 614 may not have a hollowed-out area 630. A greater degree of bending of the strip segment 614 can be understood as a greater number of corners on the inner ring edge 611 or the outer ring edge 612 of the strip segment 614, resulting in multiple bends or even folds in the strip segment 614. Alternatively, a greater degree of bending of the strip segment 614 refers to a greater abrupt change in the curvature of the corners on the inner ring edge 611 or the outer ring edge 612 of the strip segment 614.

[0108] This design allows for the extension of the length of the strip segment 614 within a limited space, extending the current path of the feed current in the radiator 610. At the same time, by not setting a cutout area 630 on the strip segment 614, the strip segment 614 is less prone to breakage, thereby enhancing the robustness and reliability of the strip segment 614. This reduces the processing or mounting difficulty of the antenna 60 and improves the overall reliability of the antenna 60.

[0109] In some embodiments, such as Figure 11 as well as Figure 12 As shown, the earphone 1 may include a rigid shell 70 and a flexible cover 80. An antenna 60 may be disposed on the outer surface of the rigid shell 70. The flexible cover 80 may cover the antenna 60 and the rigid shell 70. The flexible cover 80 may be connected to the rigid shell 70 through a cutout area 630 on the radiator 610. The outer surface of the rigid shell 70 refers to the surface that is away from the user's auricle 102 when worn.

[0110] In some embodiments, the rigid housing 70 may form part of the core housing 210; for example, the rigid housing 70 may be the housing on the side of the core housing 210 away from the user's auricle 102 when worn. Alternatively, in some embodiments, the rigid housing 70 may form the entire core housing 210. For example, the rigid housing 70 may form the entire core housing 210, in which case the antenna 60 may be disposed on the side of the second sidewall 214 facing away from the interior of the core housing 210.

[0111] Specifically, mounting the antenna 60 on the rigid housing 70 facilitates its processing and installation, and also prevents it from shifting. Using a flexible covering 80 to enclose both the antenna 60 and the rigid housing 70 further prevents moisture, dust, or metal particles from contacting the antenna 60, thus ensuring its communication performance. The flexible covering 80 can be a soft layer such as silicone.

[0112] Typically, if the antenna 60 is positioned between the rigid housing 70 and the flexible cladding 80, it will affect the connection between the rigid housing 70 and the flexible cladding 80 to some extent, which can easily lead to problems such as bulging of the flexible cladding 80. Therefore, the hollow area 630 in the antenna 60 allows part of the outer surface of the rigid housing 70 to be exposed, and the flexible cladding 80 can be connected to the rigid housing 70 through the exposed outer surface at the hollow area 630. This improves the connection strength between the rigid housing 70 and the flexible cladding 80 when the antenna 60 is positioned between the rigid housing 70 and the flexible cladding 80, and reduces problems such as bulging of the earphone 1.

[0113] In some embodiments, the rigid housing 70 and the flexible covering 80 can be bonded together using adhesives such as glue. Of course, in other embodiments, the rigid housing 70 and the flexible covering 80 can also be connected together by screws or clips, etc., which will not be specifically listed here.

[0114] In some embodiments, such as Figure 11 as well as Figure 12 As shown, the second capacitor plate 50 can be disposed on the outer surface of the rigid housing 70, and the second capacitor plate 50 can also be disposed in the middle position surrounded by the annular radiator 610. Furthermore, the flexible covering layer 80 can also cover the second capacitor plate 50. The bonding position between the rigid housing 70 and the flexible covering layer 80 can be staggered from the position of the second capacitor plate 50. This arrangement fully utilizes the space on the outer surface of the rigid housing 70 to improve the space utilization rate of the earphone 1. It also allows the flexible covering layer 80 to cover and protect the second capacitor plate 50, further preventing moisture, dust, or metal particles from contacting the antenna 60, thus reducing the possibility of external impurities affecting the touch function of the second capacitor plate 50.

[0115] In some embodiments, the area of ​​each cutout region 630 can be between 1.5 mm. 2 ~4.5mm 2 For example, the area of ​​each cutout zone 630 can be 1.5mm. 2 1.8mm 2 1.9mm 2 2mm2 2.5mm 2 3mm 2 4.2mm 2 Or 4.5mm 2 wait.

[0116] If the area of ​​each cutout zone 630 is less than 1.5mm 2 If the area where the antenna 60 is located on the rigid housing 70 is not strongly connected to the flexible cladding 80, the connection between the rigid housing 70 and the flexible cladding 80 will be insufficient, leading to bulging of the flexible cladding 80. If the area of ​​each cutout region 630 is greater than 4.55 mm², further issues may arise. 2 If the radiator 610 has poor overall strength, the stress is concentrated in the hollow area 630 of the radiator 610, and the radiator 610 is prone to breakage after the hollow area 630 is formed.

[0117] Therefore, the area of ​​each hollowed-out area 630 is between 1.5mm. 2 ~4.5mm 2 This not only enables a strong connection between the rigid shell 70 and the flexible cladding 80, but also ensures the communication performance of the antenna 60 and makes the antenna 60 more robust.

[0118] In some embodiments, along the width direction Y of the rigid housing 70, the size of the area on the rigid housing 70 that carries the strip segment 614 may be smaller than the size of the area that carries the hollow segment 613, and the width direction Y is the direction in which the earphone 1 is close to or away from the top of the head when worn.

[0119] Because the bending degree of the strip segment 614 is greater than that of the hollow segment 613, the length of the strip segment 614 can be extended within a limited space, thus extending the current path of the feed current in the radiator 610. Compared to the size of the area of ​​the rigid housing 70 that carries the hollow segment 613, the size of the area of ​​the rigid housing 70 that carries the strip segment 614 can be set smaller. This allows other electronic components to be placed near the area of ​​the strip segment 614 on the rigid housing 70 where the radiator 610 is located, increasing the space utilization rate of the mechanism housing 210. For example, the strip segment 614 can be disposed on the side of the rigid housing 70 near the free end 212, and the first capacitor plate 220 can be disposed on the outer surface of the rigid housing 70 and partially surround the strip segment 614.

[0120] In some embodiments, such as Figure 11 as well as Figure 12As shown, the earphone 1 may include a flexible insert 90, and the rigid housing 70 may form at least a part of the core housing 210. In other words, the connecting end 211 of the rigid housing 70 may be the connecting end 211 of the core housing 210, and the free end 212 of the rigid housing 70 may be the free end 212 of the core housing 210. The area where the antenna 60 is disposed on the rigid housing 70 may be located between the connecting end 211 and the free end 212, and the flexible insert 90 may be embedded in the free end 212 of the rigid housing 70.

[0121] The flexible insert 90 is disposed on the free end 212 of the rigid shell 70, which allows the user's ear to contact the area where the flexible insert 90 is disposed in the earphone 1 when the free end 212 extends into the concha 1021 or abuts against the user's auricle 102 (e.g., against the antihelix 1024 or against the helix 1026) while the earphone 1 is being worn, thereby improving the user's experience.

[0122] In some embodiments, the flexible insert 90 may also be wrapped by the flexible cover 80. The flexible insert 90 abuts against the user's ear through the flexible cover 80. Under the action of the flexible insert 90 and the flexible cover 80, the human body can contact the soft part of the earphone 1 to improve the user experience.

[0123] In some embodiments, the flexible insert 90 may be made of a flexible material such as silicone or TPE (thermoplastic elastomer).

[0124] In some embodiments, the rigid housing 70 may include a peninsula-shaped protrusion 810 near the free end 212, a base portion 820 connected to the protrusion 810 and near the connection end 211, and a mounting portion 830 located around the protrusion 810. The flexible insert 90 may be disposed on the mounting portion 830. This arrangement of the flexible insert 90 and the rigid housing 70 to fit together makes the connection between the flexible insert 90 and the rigid housing 70 more stable, thereby improving the structural stability of the earphone 1.

[0125] In the case of the protrusion 810, the size of the protrusion 810 may be smaller than the size of the base portion 820 along the width direction Y of the rigid shell 70. The strip-shaped segment 614 may be located at least partially on the protrusion 810, and the hollowed-out segment 613 may be located on the base portion 820.

[0126] For example, such as Figure 11 as well as Figure 12 As shown, at least a portion of the strip segment 614 is located on the protrusion 810. This portion can be shaped to extend at both ends and protrude in the middle to fit the shape of the protrusion 810, and the two ends of the strip segment 614 are respectively connected to the hollowed-out segment 613 and the power supply point 620. The dimensions of the protrusion 810 can be as follows: Figure 11As shown in the medium length F, the dimensions of the base portion 820 can be as follows: Figure 11 The intermediate length G is shown, where G is greater than F.

[0127] At least a portion of the strip segment 614 is disposed on the smaller protrusion 810, while the hollow segment 613 with the hollow area 630 is disposed on the larger base portion 820. This arrangement can make full use of the bending characteristics of the strip segment 614 and the hollow characteristics of the hollow segment 613. Not only can the position of the flexible insert 90 be avoided on the outer surface of the rigid housing 70, but the current path can also be extended as much as possible, thereby improving space utilization.

[0128] Of course, in other embodiments, the flexible insert 90 and the rigid housing 70 can be fitted together in other ways. For example, the flexible insert 90 may have a protruding portion, and the rigid housing 70 may have a recessed portion in the middle. The protruding portion and the recessed portion fit together to connect the flexible insert 90 and the rigid housing 70. The strip segment 614 can be bent and extended to both sides of the recessed portion to avoid the position of the flexible insert 90, and can also increase the current path and improve space utilization. Of course, the flexible insert 90 and the rigid housing 70 can also have other connection methods, which will not be specifically listed here in this embodiment.

[0129] In some embodiments, the width of the cutout segment 613 may be greater than the width of the strip segment 614.

[0130] The width direction of the hollowed-out segment 613 is perpendicular to its extension direction, and the width direction of the strip-shaped segment 614 is perpendicular to its extension direction. The width of the hollowed-out segment 613 can be the same as the width of the radiator 610 portion having the hollowed-out area 630. As an example, the width of a certain point in the hollowed-out segment 613 can be as follows: Figure 11 As shown in the figure, the width of a certain point in the strip segment 614 can be as follows: Figure 11 The width H is shown in the figure.

[0131] Setting the width of the hollow segment 613 to be greater than the width of the strip segment 614 allows full utilization of the bending characteristics of the strip segment 614 and the hollow characteristics of the hollow segment 613, facilitating the creation of the hollow area 630 within the hollow segment 613 and increasing the current path of the hollow segment 613. Conversely, setting the width of the strip segment 614 to be smaller allows for full bending of the strip segment 614, resulting in a longer current extension path, thereby reducing the SAR value and improving the space utilization near the area where the strip segment 614 is located.

[0132] In some embodiments, such as Figure 11 as well as Figure 13As shown, the hollow area 630 may include a main body area 633 and a connecting area 634. The main body area 633 may be located inside the radiator 610, and the connecting area 634 may connect the main body area 633 to the inner ring edge 611 or the outer ring edge 612, and the area of ​​the connecting area 634 is smaller than the area of ​​the main body area 633. This design can minimize the processing difficulty of the hollow area 630 while ensuring the overall strength of the radiator 610.

[0133] In some embodiments, the connecting area 634 of the first hollow area 631 can connect the main body area 633 of the first hollow area 631 with the inner ring edge 611, and the connecting area 634 of the second hollow area 632 can connect the main body area 633 of the second hollow area 632 with the outer ring edge 612. In this way, the first hollow area 631 and the second hollow area 632 can be alternately arranged, allowing the current path of the radiator 610 to exhibit an "S" shape, thereby extending the current path in the radiator 610.

[0134] In some embodiments, the circumferential dimension of the main body region 633 along the radiator 610 may be larger than the circumferential dimension of the connecting region 634 along the radiator 610.

[0135] In some embodiments, the main body area 633 and the connecting area 634 can make the cutout area 630 present a T-shaped or T-shaped configuration.

[0136] The circumferential direction of the radiator 610 is the same as the extension direction of the radiator 610 described above. As an example, the circumferential direction of the radiator 610 at a certain location can be as follows: Figure 13 Shown in the middle direction Q.

[0137] The connecting area 634 can be located at the center of the main body area 633 along the circumference of the radiator 610, so that the cutout area 630 is T-shaped. As an example, the width of the main body area 633 along the circumference can be as follows: Figure 13 As shown in Figure I, the width of the connecting region 634 along the circumferential direction can be as follows: Figure 13 As shown in J.

[0138] In other embodiments, the connecting area 634 may be located on the left or right side of the central axis corresponding to the main body area 633 along the circumference of the radiator 610, so that the hollow area 630 is arranged in a T-shape.

[0139] This design allows for a longer path for the feed current to be transmitted in the radiator 610, facilitates the fabrication and shaping of the antenna 60, and makes the radiator 610 less prone to breakage at the cutouts, thereby improving the reliability of the antenna 60.

[0140] Of course, in other embodiments, the cutout area 630 can also be other shapes, such as circular, triangular, trapezoidal or irregular shapes, etc., which will not be specifically listed here.

[0141] In summary, this application provides a first capacitor plate 220 in the core housing 210 of the earphone 1. The core housing 210 has a free end 212 and a connecting end 211 arranged along the length direction X. The free end 212 extends into the concha 1021 or abuts against the auricle 102. The first capacitor plate 220 is located in a 5-divided area of ​​the core housing 210 along the length direction X closest to the free end 212. This allows the first capacitor plate 220 to be closer to the concha 1021 or the user's auricle 102, enabling the first capacitor plate 220 to more accurately determine whether the free end 212 extends into the concha 1021 or abuts against the user's auricle 102. This can minimize the chance of accidental triggering when the user picks up the earphone 1, thereby reducing the probability of accidental touch. The first capacitor plate 220 can more accurately determine whether the earphone 1 is being worn, thus improving the user's wearing experience.

Any equivalent structural or procedural transformations made using 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.
