Description

TECHNICAL FIELD

[0001] The utility model relates to acoustics technical field, concretely relates to an ear-hanging earphone. BACKGROUND

[0002] An earphone is a transducer unit that accepts electrical signals from a media player or receiver and uses a speaker close to the ear to convert them into audible sound waves. In order to improve the wearing reliability of the earphone, an ear-hanging earphone is designed. However, when wearing such an ear-hanging earphone, since the back of each wearer's ear is different, it will cause the ear-hanging part of the ear-hanging earphone to be unable to fit the back of the wearer's ear according to the shape of the back of the wearer's ear, thereby greatly reducing the experience of the wearer.

[0003] The patent document with the authorized announcement number CN218830542U discloses an ear-hanging earphone, which specifically discloses: including a hook-shaped part, a connecting part and a retaining part, the connecting part connects the hook-shaped part and the retaining part, wherein in the wearing state, the hook-shaped part is used to hang between the back of the user's ear and the head, the retaining part is used to contact the front side of the ear, and then the retaining part and the hook-shaped part are allowed to cooperate to clamp the ear; the connecting part is provided with a rotating shaft mechanism to allow the user to adjust the relative positions of the retaining part, the connecting part and the hook-shaped part in the three-dimensional space through the rotating shaft mechanism. The free end of the hook-shaped part 11 is provided with a hole 111, which is in a hollow structure to increase the deformation ability of the free end. Among them, the hole 111 can be a through hole and / or a blind hole, the number thereof can be one or more, and the axis direction thereof can be perpendicular to the contact surface between the free end of the hook-shaped part 11 and the user's head.

[0004] The above patent document can make the hook-shaped part and the retaining part rotate relative to the rotating shaft mechanism, and the hole for increasing the deformation ability of the hook-shaped part is arranged on the hook-shaped part. When such a hole structure is subjected to an external force, the stress is greater than that of other positions of the hook-shaped part, resulting in insufficient strain force generated at other positions. Moreover, the hook-shaped part cannot adapt to the shape of the wearer's ear, so as to effectively fit the wearer's ear, and therefore improvement is needed. UTILITY MODEL CONTENT

It can also be a mechanical connection; it can be directly connected, or it can be connected through an intermediate medium, or it can be connected between two elements. For those skilled in the art, the specific meaning of the above-mentioned terms in the utility model can be understood according to the specific circumstances.

[0063] The utility model will be further described below in combination with the drawings and specific embodiments, and the following description is only exemplary and does not limit the protection scope of the utility model.

[0064] Please refer to Figure 1 , the back of the wearer's ear 100 (i.e. the back of the ear) includes physiological sites such as the posterosuperior scaphal prominence 101, the antihelical sulcus 102, the antitragal sulcus 103, the triangular fossa prominence 104, the concha prominence 105, and the ear base 106. Further, the posterosuperior scaphal prominence 101, the triangular fossa prominence 104, and the concha prominence 105 have a certain volume and a certain degree of protrusion in the direction of the head.

[0065] Please refer to Figure 2 , the front of the wearer's ear 200 can include physiological sites such as the external auditory canal 201, the concha 202, the cymba concha 203, and the triangular fossa 204.

[0066] It needs to be further explained that the ear-hanging earphone includes left and right earphones designed in symmetry, and only the left earphone is described in detail in the utility model.

[0067] Please refer to Figures 3-13 , the utility model provides an ear-hanging earphone, which comprises a sound generating part 1, a connecting part 2 and an ear hook 3, the ear hook 3 further comprises a hook part 31 and a hook tail part 32, one end of the connecting part 2 is connected with the hook part 31, and the other end of the connecting part 2 is movably connected with the sound generating part 1.

[0068] In the wearing state, the tail part 32 is located between the back of the user's ear and the head, specifically: the tail part 32 is basically attached to the user's ear root 106. The first area (not marked in the figure) on the first surface 321 of the tail part 32 close to the back of the ear (i.e. the back of the ear 100) is recessed in the direction away from the back of the ear, and the first area and the surrounding area form a first recessed part 3211. The second area (not marked in the figure) on the second surface 322 of the tail part 32 close to the head is recessed in the direction away from the head, and the second area and the surrounding area form a second recessed part 3221.

[0069] Further comprising at least one first hole-like structure 33, the first recessed part 3211 is communicated with the second recessed part 3221 through the first hole-like structure 33, one end of the first hole-like structure 33 is located on the bottom surface of the first recessed part 3211, the other end of the first hole-like structure 33 is located on the bottom surface of the second recessed part 3221, and the central axis a of the first hole-like structure 33 is parallel to the thickness direction of the sound production part 1. On the one hand, the concha bulge 105 can be attached to the first recessed part 3211, and on the other hand, the first hole-like structure 33 breaks the integrity of the tail part 32, and the hollow part formed by the first recessed part 3211, the second recessed part 3221 and the first hole-like structure 33 can be deformed more easily under stress, thereby better dispersing the pressure in different areas. Thus, the tail part 32 is more stably attached to the ear, reducing the possibility of shaking or falling off.

[0070] Please refer to Figures 3-8 In the present embodiment, a first reference plane p1 is provided, which passes through the sound production part 1 and is perpendicular to the thickness direction of the sound production part 1. The projection of the first hole-like structure 33 on the first reference plane p1 can be a regular geometric shape or an irregular geometric shape. Preferably, in the present embodiment, the projection of the first hole-like structure 33 on the first reference plane p1 is an irregular geometric shape (similar to a water droplet shape) with a narrow top and a wide bottom. Further, along the extension direction of the tail part 32, the width of the projection of the first hole-like structure 33 gradually increases from the top end to the end, where the top end refers to the end of the first hole-like structure 33 close to the hook part 31, and correspondingly, the end refers to the end of the first hole-like structure 33 away from the hook part 31. Further, the number of first hole-like structures 33 is two or more, which can be two, three or four, and is not limited here.

[0071] In the present embodiment, the number of the first hole-like structures 33 is preferably two, for the convenience of description, one of the first hole-like structures 33 is marked as the first through-hole 331, and the other of the first hole-like structures 33 is marked as the second through-hole 332. The first through-hole 331 and the second through-hole 332 are arranged in a spaced manner along the extension direction of the ear hook 32, and the end of the first through-hole 331 is opposite to the top end of the second through-hole 332. In the present embodiment, the width d1 of the projection of the first through-hole 331 on the first reference plane p1 is in the range of 0.5mm-1.2mm, and the width d2 of the projection of the second through-hole 332 on the first reference plane p1 is in the range of 1.7mm-2.8mm, and the distance d3 between the end of the first through-hole 331 and the top end of the second through-hole 332 is at least 3.7mm. Thus, the overall width of the projection of the first through-hole 331 on the first reference plane p1 is less than the overall width of the projection of the second through-hole 332 on the first reference plane p1. Therefore, in the wearing state, the first through-hole 331 provides a certain flexibility, but still maintains a good supporting force, ensuring the overall stability of the ear hook 32. The second through-hole 332 provides more elasticity and adaptability, so that the area of the ear hook 3 in contact with the concha ridge 105 can be flexibly adjusted, improving the fit feeling.

[0072] In the present embodiment, a partition 34 is arranged between the first through-hole 331 and the second through-hole 332, one surface of the partition 34 is located at the bottom surface of the first recess 3211, and the other surface of the partition 34 is located at the bottom surface of the second recess 3221. For better description of the partition 34, one surface of the partition 34 is marked as the first partition surface 341, and the other surface of the partition 34 is marked as the second partition surface 342. The first partition surface 341 of the partition 34 can be a plane or a curved surface, and the second partition surface 342 of the partition 34 can also be a plane or a curved surface. In the present embodiment, the first partition surface 341 and the second partition surface 342 are preferably curved surfaces. Specifically, the width of the projection of the first partition surface 341 on the first reference plane p1 gradually increases from the middle to the side of the first recess 3211, and the width of the projection of the second partition surface 342 on the first reference plane p1 gradually increases from the middle to the side of the second recess 3221. Compared with a plane, designing the first partition surface 341 and the second partition surface 342 as curved surfaces can not only make the appearance of the partition 34 more smooth and fluent, but also effectively disperse the load and increase the overall anti-deformation ability due to the arc design of the curved surface, which can generally provide better structural strength, especially when subjected to forces in multiple directions.

[0073] Furthermore, the curvature of the first separating surface 341 may be greater than, equal to, or less than the curvature of the second separating surface 342. Preferably, in this embodiment, the curvature of the first separating surface 341 is equal to the curvature of the second separating surface 342, making the stress distribution on the entire surface of the separator 34 more uniform, avoiding stress concentration caused by abrupt changes in local curvature, thereby reducing the risk of local fatigue or damage to the separator 34.

[0074] Furthermore, the cross-sectional area of ​​the partition 34 on the side near the first through hole 331 is smaller than the cross-sectional area of ​​the partition 34 on the side near the second through hole 332. This is equivalent to the cross-sectional area of ​​the partition 34 gradually increasing along the extension direction of the hanging tail portion 32, so that the width of the projection of the end of the first through hole 331 onto the first reference surface p1 is smaller than the width of the projection of the top of the second through hole 332 onto the first reference surface p1.

[0075] In this embodiment, the portion of the first recess 3211 located on the first surface 321 is defined as the first opening 32111, and the portion of the second recess 3221 located on the second surface 322 is defined as the second opening 32211.

[0076] like Figures 8-9 As shown, in the cross-section of the ear loop 3 at A-A', the first separating surface 341 and the first opening 32111 have a first distance L1, and the second separating surface 342 and the second opening 32211 have a second distance L2. Combined with the aforementioned: the width of the projection of the first separating surface 341 onto the first reference surface p1 gradually increases from the middle towards the first recess 3211, and the width of the projection of the second separating surface 342 onto the first reference surface p1 gradually increases from the middle towards the second recess 3221. Therefore, the first through hole 331 can communicate with the second through hole 332. Of course, even if the values ​​of the first distance L1 and the second distance L2 are 0 (equivalent to the first separating surface 341 coinciding with the first opening 32111, and the second separating surface 342 coinciding with the second opening 32211), based on the characteristic that the first separating surface 341 and the second separating surface 342 are arc surfaces that are narrow in the middle and wide at both sides, the first through hole 331 can still communicate with the second through hole 332. The design of connecting the first through hole 331 and the second through hole 332 can improve the deformation resistance of the tail section 32 without sacrificing the overall structural strength of the tail section 32 by reasonably distributing the pressure, thereby enhancing its durability.

[0077] On a cross-section parallel to the thickness direction of the tail section 32 and the sound-emitting section 1, the depth of the first recess 3211 can be greater than, equal to, or less than the depth of the second recess 3221. Preferably, in this embodiment, the depth of the first recess 3211 is equal to the depth of the second recess 3221. Specifically, please refer to... Figure 9, along the extension direction of the tail part 32, the straight-line distance from the reference plane P2 to the first opening 32111 is defined as L3, and the straight-line distance from the reference plane P2 to the second opening 32211 is defined as L4. When L3 and L4 are equal, the depth of the first recessed part 3211 is equal to the depth of the second recessed part 3221. This design, by setting the depth of the first recessed part 3211 and the depth of the second recessed part 3221 to the same value, makes the first recessed part 3211 and the second recessed part 3221 symmetrically arranged, the first partition surface 341 and the second partition surface 342 symmetrically arranged, and the two parts of the first hole-like structure 33 in the thickness direction and centered on the reference plane P2 also symmetrically arranged. This symmetrical design can balance / strengthen the force in each direction of the tail part 32, forming a stable mechanical system, which helps to reduce stress concentration caused by external force, so that the tail part 32 can effectively resist external load and impact, and maintain the integrity of the structure of the entire tail part 32.

[0078] Please refer to Figure 4 In this embodiment, the projected area of the first recessed part 3211 on the reference plane P1 gradually decreases in the direction away from the rear side of the ear part, and the projected area of the second recessed part 3221 on the reference plane P1 gradually decreases in the direction away from the head part. Specifically, taking the first recessed part 3211 as an example: a first reference line s1, a second reference line s2, a third reference line s3, and a fourth reference line s4 parallel to the length direction of the sound generating part 1 are provided, wherein the first reference line s1 passes through one end of the bottom surface of the first recessed part 3211 close to the hook part 31, the second reference line s2 passes through one end of the bottom surface of the first recessed part 3211 away from the hook part 31, the third reference line s3 passes through one end of the first opening 32111 close to the hook part 31, and the fourth reference line s4 passes through one end of the first opening 32111 away from the hook part 31. On the one hand, as viewed from the rear side of the ear part to the head part, the first reference line s1 is below the third reference line s3, and the second reference line s2 is above the fourth reference line s4. On the other hand, the cross-sectional area of the first opening 32111 is greater than the cross-sectional area of the bottom surface of the first recessed part 3211. Therefore, the area of the first opening 32111 is greater than the area of the bottom surface of the first recessed part 3211.

[0079] And the first opening 32111 and the bottom surface of the first recess 3211 are connected by an arc-shaped transition surface 35, which makes the larger area first opening 32111 smoothly extend to the bottom surface of the smaller area first recess 3211 in the thickness direction of the sound generating part 1. This smooth transition design of gradually decreasing area from outside to inside can increase the contact area between the wearer's concha cavity bulge 105 and the first recess 3211 (more precisely, the arc-shaped transition surface 35), so that the tail part 32 fits the wearer's ear back 100, improves the wearing stability of the utility model, and avoids slipping.

[0080] Since the first recess 3211 and the second recess 3221 are symmetrically arranged, the projection area of the second recess 3221 on the reference surface P1 gradually decreases in the direction away from the head, and the specific structure corresponds to the first recess 3211, which will not be repeated here.

[0081] Please refer to Figure 3 In the embodiment, the first sound pickup hole 36 is included, and the opening of the first sound pickup hole 36 can be arranged on the side surface of the first through hole 331, or on the side surface of the second through hole 332. Preferably, the first sound pickup hole 36 of the embodiment is arranged on the side surface of the second through hole 332, the central axis b of the first sound pickup hole 36 intersects the end surface of the tail end of the tail part 32, and part of the opening of the first sound pickup hole 36 is located on the side surface of the first recess 3211, and the other part of the opening of the first sound pickup hole 36 is located on the side surface of the second recess 3221. Further, in the embodiment, the area of the opening of the first sound pickup hole 36 located on the side surface of the first recess 3211 is equal to the area of the opening of the first sound pickup hole 36 located on the side surface of the second recess 3221.

[0082] Specifically, since the two parts of the aforementioned first hole structure 33 in the thickness direction and centered on the reference surface P2 are symmetrically arranged, the first sound pickup hole 36 always intersects the second reference surface p2. This design makes the first sound pickup hole 36 have a certain distance from the external environment on both sides of the tail part 32 in the thickness direction, which can avoid the first sound pickup hole 36 being directly exposed in the touchable area and generating noise by being rubbed by hair, hands, etc. collected by the feed-forward microphone. On the other hand, it can avoid the opening of the first sound pickup hole 36 being blocked, so that it cannot collect external noise.

[0083] Please refer to Figure 4 and Figure 7In the present embodiment, the cross-sectional area of the ear hook 3 gradually increases along the extension direction of the tail 32, and therefore, the inner end of the tail 32 is provided with a noise reduction signal processing unit (not shown in the figure), and the central axis b of the first sound pickup hole 36 intersects the noise reduction signal processing unit. The microphone (not shown in the figure) of the feed-forward microphone of the noise reduction signal processing unit is arranged in the first sound pickup hole 36, and a wire 37 is arranged along the length direction of the ear hook 3, and the noise reduction signal processing unit is electrically connected to the circuit board (not shown in the figure) arranged in the sound production part 1 through the wire 37. The design of arranging the noise reduction signal processing unit at the inner end of the tail 32 can make the weight of the ear hook type earphone more uniform, avoid the excessive concentration of the center of gravity on the sound production part 1, and improve the wearing comfort. The surface of the wire 37 is provided with an elastic wire 39, which can play a buffering / protection role on the wire 37, prolong the service life of the wire 37, and on the other hand, provide a certain flexibility for the ear hook 3, allowing the ear hook 3 to be bent to a certain extent during wearing.

[0084] Further, in the wearing state, the first surface 321 and the second surface 322 intersect in the direction close to the ear root 106, and the first surface 321 and the second surface 322 intersect with the third surface 323 in the direction away from the ear root 106. Specifically, the first surface 321 and the second surface 322 are symmetrically arranged with the reference plane P2 as the center, and one side of the first surface 321 and one side of the second surface 322 gradually extend in the direction close to the reference plane P2 until they intersect (i.e., one side of the first surface 321 and one side of the second surface 322 are connected to each other), the other side of the first surface 321 and the other side of the second surface 322 extend in the direction away from the reference plane P2 until the other side of the first surface 321 intersects with one side of the third surface 323 and is connected to each other, and the other side of the second surface 322 intersects with the other side of the third surface 323 and is connected to each other. At this time, the first surface 321, the second surface 322 and the third surface 323 form a three-dimensional triangular shape. In general, the cross-sectional area of the tail 32 gradually decreases from the direction away from the ear root 106 to the direction close to the ear root 106. This design can better adapt to the angle between the wearer's ear and head, so that the tail 32 can better fit the natural angle and shape of the ear back 100, and increase the stability of the earphone when worn.

[0085] Further, please refer to Figure 13, a third reference plane p3 is provided, the third reference plane p3 passes through the end of the tail part 32 and is perpendicular to a plane in the length direction of the sound production part 1. At least part of the end of the sound production part 1 close to the tail part 32 is located on the third reference plane p3, that is, the tail part 32 bends and extends towards the sound production part 1, and the end of the tail part 32 is located below the end of the sound production part 1 close to the tail part 32. Specifically, in the wearing state, taking the third surface 323 of the tail part 32 as an example, the third surface 323 of the tail part 32 extends towards and below the sound production part 1. At this time, the third reference plane p3 is located at least at 1 / 3 of the length of the sound production part 1.

[0086] In the present embodiment, please refer to Figure 4 , Figure 10 and Figure 11 , a fourth reference plane p4 is provided, the fourth reference plane p4 passes through the end of the tail part 32 and is parallel to the thickness direction of the sound production part 1. A second hole structure 38 is provided on the tail part 32. Further, the projection of the second hole structure 38 on the fourth reference plane p4 can be a regular geometric shape or an irregular geometric shape. Preferably, in the present embodiment, the second hole structure 38 is an irregular geometric shape. Specifically, from the direction opposite to the third surface 323 of the tail part 32, the width of the second hole structure 38 gradually increases along the direction in which the tail part 32 extends. This irregular geometric shape can to some extent disperse the stress received by the tail part 32 in the wearing state, reduce the risk of damage caused by stress concentration, and thus improve the durability of the earphone.

[0087] In the present embodiment, one end of the second hole structure 38 is arranged on the third surface 323 and forms an outer contour 381, the other end of the second hole structure 38 is arranged in the first hole structure 33 and forms an inner contour 382, and the projection area of the second hole structure 38 on the fourth reference plane p4 gradually decreases from the third surface 323 to the direction close to the ear root 106, so the cross-sectional area of the outer contour 381 is larger than that of the inner contour 382. The advantage of this structure is that when the environmental noise from the outside world passes through the outer contour 381 with a larger cross-sectional area, the inner contour 382 with a smaller cross-sectional area, and finally enters the first hole structure 33, the environmental noise is equivalent to a focusing effect, so that the feed-forward microphone can effectively capture the environmental noise from the outside world.

[0088] Specifically, in the present embodiment, the number of second hole structures 38 can be one, two or three, etc. Preferably, in the present embodiment, the number of second hole structures 38 is two. In order to better illustrate the two second hole structures 38, one of the second hole structures 38 is marked as a third through hole 383, and the other second hole structure 38 is marked as a fourth through hole 384. The arrangement of the third through hole 383 and the fourth through hole 384 can make the sound pickup hole pick up noise in multiple directions.

[0089] One end of the third through hole 383 is arranged on the third surface 323 of the ear hook 32, and the other end of the third through hole 383 is arranged in the first through hole 331, i.e. the third through hole 383 communicates with the first through hole 331. One end of the fourth through hole 384 is arranged on the third surface 323 of the ear hook 32, and the other end of the fourth through hole 384 is arranged in the second through hole 332, i.e. the fourth through hole 384 communicates with the second through hole 332. From the direction opposite to the third surface 323 of the ear hook 32, the third through hole 383 and the fourth through hole 384 are arranged in the extension direction of the ear hook 32, and the end of the third through hole 383 is opposite to the top end of the fourth through hole 384.

[0090] Further, the projection area of the third through hole 383 on the fourth reference plane p4 gradually decreases from the third surface 323 to the first through hole 331, so that the third through hole 383 forms a first outer contour 3831 on the third surface 323 and a first inner contour 3832 in the first through hole 331, and the cross-sectional area of the first outer contour 3831 is greater than that of the first inner contour 3832. Similarly, the projection area of the fourth through hole 384 on the fourth reference plane p4 gradually decreases from the third surface 323 to the second through hole 332, so that the fourth through hole 384 forms a second outer contour 3841 on the third surface 323 and a second inner contour 3842 in the second through hole 332, and the cross-sectional area of the second outer contour 3841 is greater than that of the second inner contour 3842. Please refer to Figure 10 In the present embodiment, in the direction opposite to the third surface 323 of the ear hook 32, the width d4 of the first inner contour 3832 ranges between 0.8mm-1.1mm, the width d5 of the second inner contour 3842 ranges between 1.0mm-1.5mm, and the distance d6 between the first inner contour 3832 and the second inner contour 3842 is at least 6.6mm, and the distance d7 between the first outer contour 3831 and the second outer contour 3841 is at least 3.5mm. Thus, the overall width of the third through hole 383 is substantially greater than that of the fourth through hole 384, which can conform to the structural feature that the cross-sectional area of the ear hook 32 gradually increases in the extension direction, thereby improving the visual appeal of the ear hook earphone.

[0091] Please refer to Figure 7 , Figure 8 and Figure 12In the embodiment, one end of the hook portion 31 is fixedly connected with the top end of the hook tail portion 32, and the other end of the hook portion 31 is provided with a first plug 311. Correspondingly, the connecting portion 2 comprises a first sub-connecting portion 21 and a second sub-connecting portion 22 arranged at an angle. The first sub-connecting portion 21 is in a cylindrical shape, and the first sub-connecting portion 21 is matched with the first plug 311. The ear hook 3 and the connecting portion 2 are connected by inserting the first plug 311 into the first sub-connecting portion 21.

[0092] Further, the second sub-connecting portion 22 is provided with a second plug 221, and the sound production portion 1 is provided with a mounting hole 11 matched with the second plug 221. The second plug 221 is rotationally connected with the mounting hole 11, so that the ear hook 3 can swing around the second sub-connecting portion 22. Further, the second sub-connecting portion 22 is provided with a channel 222, and the sound production portion 1 is provided with a limiting piece 12 further provided with a plurality of protrusions 121. The sizes of the protrusions 121 are basically consistent with the size of the channel 222. When the ear hook 3 swings around the second sub-connecting portion 22, the channel 222 will abut against the protrusions 121 on the limiting piece 12 in sequence, so that the wearer stops rotating the ear hook 3 when the ear hook 3 is attached to the ear root 106. Correspondingly, the protrusions 121 will block the channel 222, so that the ear hook 3 is kept in a stationary state to avoid moving away from the ear root 106.

[0093] The working principle of the utility model will be introduced below, so as to better understand the utility model:

[0094] First, the sound production portion 1 is attached to the concha cavity 202, and then the ear hook 3 is rotated to be attached to the ear root 106. At this time, the first recess 3211 on the hook tail portion 32 is attached to the concha cavity protrusion 105, and the second recess 3221 on the hook tail portion 32 is attached to the head, so that the hook tail portion 32 is more stably attached to the ear, reducing the possibility of shaking or falling off. Subsequently, since the second through hole 332 is a certain distance away from the first opening 32111 and the second opening 32211 respectively, the pickup hole arranged on the side of the second through hole 332 can effectively avoid touching the body and hair, and isolate the abnormal noise collected by the feed-forward microphone.
