[0001] This utility model relates to the technical field of wearable devices, and in particular to an ear clip-on earphone. Background Technology

[0002] Clip-on headphones are an innovative headphone design that differs from traditional in-ear or over-ear headphones. They securely fasten to the ears using a clip, and are commonly found in sports headphones and other devices that require prolonged wear. Due to their excellent comfort and stability, they have a wide range of applications.

[0003] Typically, clip-on headphones include a speaker, an ear clip, and an ear bridge. The speaker and ear clip are located at both ends of the ear bridge, and the ear bridge can apply a clamping force to the speaker and ear clip so that the speaker and ear clip can be clamped and fixed on opposite sides of the ear.

[0004] However, current clip-on headphones still have many shortcomings. For example, when actually worn, the sound emitted by the speaker may be blocked and cannot be fully transmitted into the ear canal, affecting the user experience. Therefore, existing technology needs to be improved.

[0005] The above information is provided as background information only to aid in understanding this disclosure and does not constitute an assertion or admission that any of the above content can be used as prior art relative to this disclosure. Utility Model Content

[0048] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0049] In the description of this utility model, it should be understood that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component that is centrally positioned therein. When a component is considered to be "set" on another component, it can be directly set on the other component or there may be a component that is centrally positioned therein.

[0050] Furthermore, terms such as "long," "short," "inner," and "outer" indicate orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings. They are used only for the convenience of describing this utility model and do not indicate or imply that the device or component referred to must have this specific orientation or operate in a specific orientational configuration. Therefore, they should not be construed as limitations of this utility model.

[0051] It should be explained that, in order to more clearly illustrate the use effect and functional application of the technical solution described in this utility model, this embodiment uses an ear simulator 9 (model GRASRA0045) as the wearing carrier. It can be understood that the ear simulator 9 usually refers to a tool that simulates the function of the human auditory system. Its core purpose is to reproduce the human ear's ability to receive, process, and locate sound. It can be used as an ear testing model. Although there are individual differences among different users, the ear simulator 9 can represent the application scenarios of most users. Therefore, it is beneficial for the solution provided by this utility model to achieve functional reproduction on most users. The solution mentioned in this embodiment is mainly described in the wearing state.

[0052] Furthermore, referring to Figure 1 The user's ear mainly includes physiological parts such as the ear canal 1001, helix 1002, crus of the helix 1003, antihelix 1004, tragus 1005, antitragus 1006, and concha 1007. The side of the ear furthest from the head is defined as the front of the ear, and the side closest to the head is defined as the back of the ear. Physiological parts such as the helix 1002, antihelix 1004, crus of the helix 1003, tragus 1005, and antitragus 1006 all protrude towards the front of the ear. The concha 1007 is surrounded by the crus of the helix 1003, tragus 1005, antihelix 1004, and antitragus 1006, creating a concave state. At this time, the opening of the ear canal 1001 ( Figure 1 The unmarked part (hereinafter referred to as the ear canal opening 1008) is located at the bottom of the concha cavity 1007. When wearing headphones, users usually insert the speaker into the concha cavity 1007. With the support of physiological parts such as the helix 1002, antihelix 1004, helix crus 1003, and tragus 1005, it can be stably worn in the user's ear.

[0053] However, currently, for clip-on headphones, the headphones need to be clipped to the front and back of the ear to achieve a more stable wearing effect. However, conventional clip-on headphones still have the problem of incomplete sound transmission, making it difficult to achieve a good user experience. Therefore, this embodiment provides a clip-on headphone to overcome this problem.

[0054] The following is in conjunction with the appendix Figures 2-9 The technical solution of this utility model will be further illustrated through specific implementation methods.

[0055] Please refer to Figure 2 This utility model provides an earphone, which includes a semi-in-ear speaker 2, an ear clip 3, and an ear bridge 4. The semi-in-ear speaker 2 and the ear clip 3 are respectively disposed at both ends of the ear bridge 4.

[0056] Among them, the ear bridge 4 is usually formed by wrapping steel wire and wire with plastic layer. The steel wire can provide elastic clamping force, while the wire plays a transmission role.

[0057] Furthermore, the ear clip 3 typically includes components such as a housing, a main board 6, an antenna bracket, a battery, and a main control chip (not shown in the figure). The main board 6 is connected to the cable and installed inside the housing, which is fixedly connected to one end of the ear clip 4 for protection. The antenna bracket, battery, and main control chip are integrated on the main board 6 and perform communication and control functions respectively.

[0058] The semi-in-ear speaker 2 includes a housing and a speaker. The housing is fixedly connected to the other end of the ear bridge 4. The housing extends from the side closer to the ear bridge 4 to the side farther away from the ear bridge 4, forming a relatively long and narrow extension profile. This allows the semi-in-ear speaker 2 to penetrate deep into the ear canal 1001 when worn, achieving the purpose of semi-in-ear function, improving the airtightness of the structure, and reducing the occurrence of sound leakage. It can be understood that the extension direction of the housing can be regarded as its length direction, and the housing has a width direction perpendicular to the length direction. At the same time, the speaker is installed inside the housing. At this time, the speaker is connected to the main board 6 through a wire and emits sound under the control of the main control chip.

[0059] Typically, clip-on headphones are worn horizontally, clamping onto the user's ear; see reference. Figure 3 Using the horizontal plane as a reference, Figure 3 The viewpoint shown is the horizontal projection viewpoint of the headphones when they are worn; therefore, Figure 3 The headphones are projected onto a horizontal plane in the wearing state, making it easier to visually check their wearing status.

[0060] Meanwhile, the semi-in-ear speaker 2 is provided with a sound outlet 21, which is installed through the outer shell and located at the end of the outer shell away from the ear bridge 4. At this time, the outer shell is long and narrow, which allows the sound outlet 21 to be close to the ear canal opening 1008. At this time, the speaker is installed inside the outer shell opposite to the sound outlet 21. The sound emitted by the speaker is transmitted to the outside through the sound outlet 21, thereby realizing sound transmission. It can be seen that the orientation angle of the sound outlet 21 is equivalent to the direction of sound transmission.

[0061] To ensure that sound can be transmitted completely to the ear canal opening at 1008, specifically, based on Figure 3From the perspective shown, a distance is selected between the semi-in-ear speaker 2 and the ear clip 3, and this distance is defined as L1, which is equivalent to obtaining the shortest distance between the two. At the same time, a center of the distance is selected at the middle position of L1, and a vertical center line is drawn at the center of the distance, which is defined as I. Furthermore, a sound output axis is selected on the semi-in-ear speaker 2, and the sound output axis is defined as Q. The sound output axis Q is consistent with the orientation of the sound outlet 21, that is, the sound output axis Q is equivalent to the direction of sound transmission.

[0062] At this time, under the horizontal projection view when the headphones are in the wearing state, an angle is formed between the vertical center line I and the sound output axis Q. This angle is defined as α. Furthermore, the value range of the angle α formed by the vertical center line and the sound output direction of the sound output hole 21 is 10°-40° to solve the problem of incomplete sound output.

[0063] Based on the above settings, it is understandable that, through actual wearing tests, when the value of α is less than 10°, the sound outlet 21 is closer to the concha 1007 and is blocked by the cavity wall of the concha 1007, which hinders sound transmission and thus affects the headphone's sound transmission effect. Conversely, when the value of α is greater than 40°, the sound outlet 21 is closer to the tragus 1005 and is blocked by the inner wall of the tragus 1005, which also hinders sound transmission. Therefore, by controlling the included angle α between 10° and 40°, the sound outlet 21 can be precisely aligned with the ear canal opening 1008, achieving directional sound transmission and optimizing the headphone's sound quality experience.

[0064] For example, the angle α formed by the vertical centerline and the sound output direction of the sound outlet 21 can specifically be 10°, 11°, 12°, 13°, 14°, 15°, 16°, 17°, 18°, 19°, 20°, 21°, 22°, 23°, 24°, 25°, 26°, 27°, 28°, 29°, 30°, 31°, 32°, 33°, 34°, 35°, 36°, 37°, 38°, 39°, 40°, etc. In another embodiment, the angle α can also be selected between any two of the above-mentioned numerical ranges.

[0065] Based on the above settings, by adopting a semi-in-ear speaker 2, the sound outlet 21 can be closer to the ear canal opening 1008. Combined with the sound outlet angle setting of the sound outlet 21, a directional sound transmission effect can be formed, so that the sound can be transmitted more completely into the ear canal 1001, and the user experience is optimized and improved.

[0066] Furthermore, in this embodiment, the angle formed by the vertical centerline and the sound output direction of the sound outlet 21 is in the range of 23°-25°. However, in actual wear, due to differences in individual wearing habits and ear structure, there may be a certain deviation between the actual and ideal wearing state of the semi-in-ear speaker 2, leading to improper or misaligned placement. Therefore, by further narrowing the range of the angle α, when the angle α is within the aforementioned range, the sound transmission direction can accurately point towards the ear canal opening 1008 even when improperly placed, which is closer to the human physiological environment and results in the best sound transmission effect.

[0067] For example, the included angle α can be 23°, 23.1°, 23.2°, 23.3°, 23.4°, 23.5°, 23.6°, 23.7°, 23.8°, 23.9°, 24°, 24.1°, 24.2°, 24.3°, 24.4°, 24.5°, 24.6°, 24.7°, 24.8°, 24.9°, 25°, etc. In another embodiment, the included angle α can also be selected between any two of the above-mentioned numerical ranges, without specific limitations.

[0068] Furthermore, referring to Figure 4 In this embodiment, the opening outline of the sound outlet 21 is elliptical. Normally, the opening outline of the human ear canal 1008 is similar to that of an ellipse. By setting the sound outlet 21 to an elliptical shape, the sound outlet 21 can be made to fit better with the opening outline shape of the ear canal 1008, thereby optimizing the sound transmission effect.

[0069] Based on this, the elliptical sound outlet 21 has a major axis and a minor axis. The extension direction of the major axis is consistent with the length direction of the sound outlet 21, and the extension direction of the minor axis is consistent with the width direction of the sound outlet 21. Here, the major axis distance is defined as L2, and the minor axis distance is defined as L3. The major axis distance L2 of the sound outlet 21 is greater than the minor axis distance L3 of the sound outlet 21. Optionally, the major axis distance L2 of the sound outlet 21 is 6mm-9mm, and the minor axis distance L3 of the sound outlet 21 is 4mm-7mm.

[0070] Understandably, when the long axis distance L2 is greater than 9mm, the length of the sound outlet 21 will be greater than the opening length of the ear canal 1008, resulting in a partial blockage of the sound outlet 21 in the length direction, affecting the integrity of sound transmission. Conversely, when L2 is less than 6mm, the length of the sound outlet 21 will be too short, preventing sound from being transmitted from inside the shell to the outside, which will also affect the integrity of sound transmission. Furthermore, when the short axis distance L3 is greater than 7mm, the width of the sound outlet 21 may be greater than the opening width of the ear canal 1008, resulting in a partial blockage of the sound outlet 21 in the width direction, affecting the integrity of sound transmission. Conversely, when L2 is less than 4mm, the opening width of the sound outlet 21 will be too small, preventing sound transmission and affecting the integrity of sound transmission.

[0071] Therefore, by setting the long axis distance L2 to 6mm-9mm and the short axis distance L3 of the sound outlet 21 to 4mm-7mm, this embodiment can make the sound outlet 21 have a suitable area size, thereby maintaining the integrity of sound transmission and optimizing the user experience.

[0072] For example, the specific parameters of the long wheelbase L2 can be 6mm, 7mm, 8mm, or 9mm. In another embodiment, the value of the long wheelbase L2 can also be selected between any two of the above-mentioned numerical ranges. In addition, the specific parameters of the short wheelbase L3 can be 4mm, 5mm, 6mm, or 7mm. In another embodiment, the value of the short wheelbase L3 can also be selected between any two of the above-mentioned numerical ranges.

[0073] Based on the above example, in one of the combinations provided in this embodiment, the long axis distance L2 is 8mm and the short axis distance L3 is 6mm. This results in a sound outlet 21 with a moderate area, which, while satisfying the function of directional sound transmission, can maximize the sound output range of the sound outlet 21, thereby optimizing and improving the overall listening experience. It is understood that the specific parameter combination between L2 and L3 can be adjusted according to the actual design requirements of the sound outlet 21, and there is no restriction on the combination of long axis distance L2 and short axis distance L3.

[0074] Further reference Figure 4A front mouth tuning mesh 11 is provided inside the sound outlet 21, and the porosity of the front mouth tuning mesh 11 is 20%-40%. Specifically, when the porosity of the front mouth tuning mesh 11 is less than 20%, it will cause severe attenuation of high frequencies, resulting in a lack of transparency and airiness in the listening experience. Furthermore, prolonged wear can easily lead to ear fullness, fatigue, and ear discomfort. On the other hand, when the porosity of the front mouth tuning mesh 11 is greater than 40%, it may lead to excessive release of high-frequency energy, such as sharp sibilance, cymbal sounds, or electronic sound effects, which can be harsh and may also reduce sound density and blur the imaging (such as fluctuating vocal positions and inaccurate instrument positioning), resulting in a lack of solidity and immersion in the listening experience. It may also lead to poor passive sound insulation, allowing external noise (such as traffic noise and human voices) to easily enter the ear, requiring the volume to be increased in noisy environments and increasing the risk of hearing damage. Therefore, this embodiment sets the porosity of the front mouth tuning mesh 11 to 20%-40%, which can achieve a more balanced sound, enhance low-frequency response, ensure high-frequency clarity, and maintain adequate airflow to improve comfort.

[0075] Furthermore, referring to Figure 5 and Figure 6 The semi-in-ear speaker 2 also has a pickup hole 22. Specifically, the pickup hole 22 is disposed through the outer shell of the semi-in-ear speaker 2 to collect sound, making the call clearer. In addition, the pickup hole 22 also participates in sound adjustment to improve the listening experience. Based on this, the pickup hole 22 has a rear cavity tuning mesh 12. The rear cavity tuning mesh 12 is used to adjust the external sound passing through the pickup hole 22, achieving the effect of noise reduction. Specifically, the porosity of the rear cavity tuning mesh 12 provided in this embodiment is 10%-30%.

[0076] It is understandable that when the porosity of the rear cavity tuning mesh 12 is less than 10%, it may cause the sound pickup hole 22 to be too isolated from external sounds, making it difficult to collect external sounds (such as not being able to hear traffic alarms), which may pose a safety hazard to users. On the other hand, when the porosity of the rear cavity tuning mesh 12 is greater than 30%, it will cause too much external noise to enter the headphones, making tuning more difficult. In this embodiment, by setting the porosity of the rear cavity tuning mesh 12 to 10%-30%, the impact of noise can be reduced, and the noise isolation effect can also be optimized.

[0077] For example, the porosity of the back cavity tuning mesh 12 can be 10%, 15%, 20%, 25% or 30%, etc. The porosity of the back cavity tuning mesh 12 can be adjusted according to the actual design requirements, and no specific limitation is made here. In another embodiment, the porosity of the back cavity tuning mesh 12 can also be selected between any two of the above-mentioned numerical ranges.

[0078] Furthermore, continue to refer to Figure 5The semi-in-ear speaker 2 has two pickup holes 22 on opposite sides. Specifically, the two pickup holes 22 are located on opposite sides in the width direction of the semi-in-ear speaker 2. Based on this arrangement, when the semi-in-ear speaker 2 is inserted into the concha cavity 1007, the width side of the semi-in-ear speaker 2 will abut against the inner edge of the antitragus 1006, which may cover the pickup hole 22. The pickup hole 22 is mainly used to collect sound to make the call clearer. In addition, the pickup hole 22 also participates in the sound adjustment. With the cooperation of the tuning mesh and tuning cotton, it helps to adjust the sound more accurately and avoid the sound becoming muddy.

[0079] Therefore, when the microphone 22 is blocked, it may affect the sound quality of the headphones. Here, by placing the microphone 22 on opposite sides of the semi-in-ear speaker 2, it can be ensured that when the headphones are worn, one of the two microphones 22 faces away from the ear. This is beneficial for adjusting the sound and ensuring good sound quality. More importantly, by setting two microphones 22 and making the headphones symmetrical, the left and right ear wearing functions of a single headphone can be realized, and the wearing experience of the headphones is further optimized and improved.

[0080] Furthermore, to ensure that the pickup hole 22 can pick up user or environmental sounds more clearly, its size and outline can be reasonably controlled to obtain a larger pickup area. In one embodiment, the pickup hole 22 has an elongated hole-shaped outline. In this case, the length of the pickup hole 22 can be changed separately to obtain a suitable pickup area. For ease of description, the length of the pickup hole 22 is defined as L4, and the length L4 of the pickup hole 22 is controlled between 2.5mm and 4.5mm.

[0081] If the length of the pickup hole 22 is less than 2.5mm, it may be too short, making it easy to be blocked when wearing the earphone, and it may also be blocked by dust and impurities over long-term use. On the other hand, if the length of the pickup hole 22 is greater than 4.5mm, it will be too long and may affect the shape and size of the semi-in-ear speaker 2. For example, the length of the pickup hole 22 can be controlled to 2.5mm, 2.6mm, 2.7mm, 2.8mm, 2.9mm, 3.0mm, 3.1mm, 3.2mm, 3.3mm, 3.4mm, 3.5mm, 3.6mm, 3.7mm, 3.8mm, 3.9mm, 4mm, 4.1mm, 4.2mm, 4.3mm, 4.4mm or 4.5mm, or the length of the pickup hole 22 can be controlled between any of the above two parameters, without specific restrictions.

[0082] Furthermore, the sound pickup effect can be altered by controlling the width of the pickup hole 22. For ease of description, the width of the pickup hole 22 is L5, specifically, L5 is 0.5mm-1.5mm. If the width of the pickup hole 22 is less than 0.5mm, it may be easily blocked. If the width of the pickup hole 22 is greater than 1.5mm, it may affect the shape and size of the semi-in-ear speaker 2. For example, the width of the pickup hole 22 can be 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, or 1.5mm. In another embodiment, the width of the pickup hole 22 can be controlled between any of the above parameters, without specific limitations.

[0083] In addition, in another embodiment, the length of the pickup hole 22 can be controlled between 2.5mm and 4.5mm and the width of the pickup hole 22 can be controlled between 0.5mm and 1.5mm. The specific parameter values ​​will not be listed here. By adopting the above technical solution, a larger pickup area can be obtained without affecting the shape and size of the semi-in-ear speaker 2, which is conducive to capturing external sounds more clearly.

[0084] Furthermore, continue to refer to Figure 6 To improve wearing comfort, based on the horizontal projection view and the vertical midline I, the ear bridge 4 is divided into two parts by the vertical midline I. One part is close to the semi-in-ear speaker part 2, while the other part is close to the ear clip part 3. At this time, the curvature of the ear bridge 4 located on one side of the vertical midline and close to the semi-in-ear speaker part 2 is less than the curvature of the ear bridge 4 located on the other side of the vertical midline and close to the ear clip part 3.

[0085] Based on the above structural design, the ear bridge 4 can form an asymmetrical structure. The curvature of the ear bridge 4 near the semi-in-ear speaker 2 is relatively straighter than that near the ear clip 3. This allows for a greater elastic swing amplitude between the ear bridge 4 and the semi-in-ear speaker 2 side when worn, thus providing a larger ear clip space. Comfortable clipping can be achieved from ear-to-ear (ear close to the head) to protruding ear (ear relatively far from the head), and from small ear (relatively narrow antihelix 1004) to large ear (relatively wide antihelix 1004). This reduces the contact between the inner contour of the earphone and the side of the antihelix 1002, which can cause compression or even tangling of the antihelix 1004. This satisfies the clip-on earphone's ability to clip and wear various ear shapes and sizes, improving the comfort of wearing the earphone.

[0086] Furthermore, the distance L1 between the semi-in-ear speaker 2 and the ear clip 3 ranges from 2.5mm to 4mm. If the distance between the semi-in-ear speaker 2 and the ear clip 3 is less than 2.5mm when worn, the gap is too small, meaning the ear bridge 4 applies too much clamping force, which can easily cause discomfort during long-term wear. Conversely, if the distance is greater than 4mm, the earphone will be too loose and may fall out due to insufficient clamping force. Therefore, by controlling the distance L1 between the semi-in-ear speaker 2 and the ear clip 3 to 2.5mm-4mm, a comfortable experience can be achieved even under long-term wear conditions.

[0087] For example, the distance between the semi-in-ear speaker 2 and the ear clip 3 can be 2.5mm, 3mm, 3.5mm or 4mm, etc., or the distance between the semi-in-ear speaker 2 and the ear clip 3 can be controlled between any two of the above parameter values, without specific restrictions.

[0088] Furthermore, continue to refer to Figure 6 An arc-shaped groove 23 is provided on the inner contour of the connection between the ear bridge 4 and the ear clip 3. At this time, the helix 1002 usually protrudes towards the back of the ear. The contour of the arc-shaped groove 23 is set to conform to the contour of the back of the ear. The arc-shaped groove 23 is used to fit the back of the helix 1002. If the inner contours of the ear bridge 4 and the ear clip 3 are flat, the ear bridge 4 will press on the back of the helix 1002 when the headphones are worn, causing discomfort. Based on the above structural design, the arc-shaped groove 23 can accommodate the back of the helix 1002 and, by fitting it, avoid and support the back of the helix 1002, thus effectively improving the comfort when wearing it.

[0089] Reference Figure 7 and Figure 8 To optimize the earphone's functional experience, the ear clip 3 has a protruding detection mirror 5 for heart rate monitoring on the side facing the semi-in-ear speaker 2. The detection mirror 5 is attached to the ear skin. At this time, the ear clip 3 is equipped with a photoelectric sensor (not shown in the figure) and an LED light (not shown in the figure). The LED light and the photoelectric sensor are connected to the main control chip. When working, the LED light emits detection green or red light through the detection mirror 5. When the light shines on the skin, some of the light is scattered and reflected by the blood. When the heart beats, the blood volume will cause a slight change. This change will cause a slight change in the emitted light, which will be captured by the photoelectric sensor and analyzed to calculate the heart rate. Therefore, in this embodiment, in order to ensure the accuracy of the heart rate monitoring function, the detection mirror 5 is set to protrude outward, which can improve the tightness of the contact between the detection mirror 5 and the skin and ensure unobstructed light path interaction.

[0090] Furthermore, referring to Figure 7 The thickness of the detection lens 5 is 0.5mm-2.0mm. For ease of explanation, the thickness of the detection lens 5 is defined as h1. It can be understood that if the thickness of the detection lens 5 is less than 0.5mm, the protrusion of the detection lens 5 may be insufficient, affecting the tightness of the fit and the heart rate monitoring effect. If the thickness of the detection lens 5 is greater than 2.0mm, the protrusion of the detection lens 5 may be too large, easily causing discomfort or leaving marks on the skin under prolonged wear, affecting the user experience. When the thickness of the detection lens 5 is 0.5mm-2.0mm, it ensures good contact between the heart rate monitoring sensor and the skin, improving the accuracy of heart rate monitoring, while also optimizing wearing comfort.

[0091] For example, the thickness of the detection mirror 5 can be 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm or 2.0mm, or the thickness of the detection mirror 5 can be controlled between any two of the above parameter values, without any specific limitation.

[0092] Furthermore, the size of the contact area of ​​the detection mirror 5 is also an important factor affecting the accuracy of heart rate monitoring. When the size of the detection mirror 5 is too small, the area illuminated by light may be too small, affecting the light intensity required for normal light judgment. When the area of ​​the detection mirror 5 is too large, light leakage may occur, which will also affect the effect of mirror detection.

[0093] The detection mirror 5 typically has an elongated shape, therefore it has both width and length. Figure 8 At this point, the width of the detection mirror 5 is defined as h2 and the length is defined as h3. The value range of h2 is controlled between 4.0mm and 7.0mm, and the value range of the length h3 of the detection mirror 5 is controlled between 6mm and 11mm, so as to obtain a suitable contact area.

[0094] If the width of the detection mirror 5 is less than 4mm and the length of the detection mirror 5 is less than 6mm, the size of the detection mirror 5 is too small; while if the length of the detection mirror 5 is greater than 7mm and the length of the detection mirror 5 is greater than 11mm, the area of ​​the detection mirror 5 will be too large. Both of these situations will affect the effect of mirror detection.

[0095] For example, the width of the detection mirror 5 can be 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm or 7mm, or the width of the detection mirror 5 can be between any two of the above parameter values; in addition, the length of the detection mirror 5 can be 6mm, 6.5mm, 7mm, 7.5mm, 8mm, 8.5mm, 9mm, 9.5mm, 10mm, 10.5mm or 11mm, or the length of the detection mirror 5 can be between any two of the above parameter values, without specific limitations.

[0096] In addition, as users' functional demands for headphones increase, more functional modules are incorporated into the headphones themselves. However, the size of the ear clip 3 has specific size requirements; based on this, referring to... Figure 9 To further optimize the structural layout and enable more functional components to be set within a limited space, this embodiment provides a connecting line 10 inside the ear bridge 4, a main board 6 inside the ear clip 3, and a connector 7 on the main board 6. Preferably, the connector 7 is a BTB connector 7. It can be understood that the BTB (Board-to-Board) connector 7 refers to a connector 7 used to connect two or more circuit boards (PCBs).

[0097] Based on this, an FPC line 8 is provided between the connector 7 and the connecting line 10. FPC is short for Flexible Printed Circuit, also known as a flexible printed circuit board. Specifically, multiple solder points can be added to the FPC to connect the connection in the ear beam 4 to the solder points on the FPC. Then, the FPC line 8 is stacked with the motherboard 6. This can increase the vertical space utilization of the motherboard 6, freeing up more space for the motherboard 6 so that more components can be added on the motherboard 6. The compactness of the structure is improved and the component layout is optimized.

[0098] Therefore, the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
