Description

Technical Field

[0001] The utility model relates to the technical field of earphones, in particular to a head-mounted earphone. Background Art

[0002] With the development of electronic technology, electronic products such as computers, mobile phones, and tablets have become part of daily life. Consequently, headphones have become a necessity. Headphones are popular because of their excellent auditory effects.

[0003] The earmuffs are designed to be rotatable, so that the earmuffs can better adapt to the ear shapes of different users. By rotating the earmuffs, the user can find the most suitable wearing angle and ensure the fit between the earmuffs and the earmuffs, thereby reducing the pressure on the earmuffs. However, in order to ensure the sound transmission efficiency and good sound insulation effect, the earmuffs are usually sealed. The earmuffs are directly attached to or in contact with the earmuffs. The shape of the earmuffs cannot fully adapt to the ear shapes of different users. In addition, the weight of the earmuffs and the earmuffs exerts pressure on the ears, which still causes great pressure on the ears. Wearing the earmuffs for a long time will cause ear discomfort or even pain. In addition, the sealing design of the earmuffs will lead to poor air permeability. Hot weather or long-term wearing will also cause the user to feel stuffy and uncomfortable. That is, in order to ensure the sound transmission efficiency and good sound insulation effect, the existing earmuffs cannot meet the needs of long-term wearing. Summary of the Invention

[0004] Based on this, the purpose of the present invention is to overcome the defects or shortcomings of the existing technology and provide a head-mounted headset that can improve wearing comfort while ensuring sound quality and meet the user's needs for long-term wearing.

[0005] The present invention is realized through the following technical solution: a headset, comprising a headband, two connecting arms, two ear shells, two earmuffs, two earmuff connectors, and a sound circuit assembly, wherein the two ends of the headband are respectively connected to the ear shells through the connecting arms, the earmuffs are connected to the ear shells through the earmuff connectors, the ear shells are provided with an inner cavity for accommodating the sound circuit assembly, the inner cavity is further provided with a rotating assembly, the side surfaces of the ear shells are provided with through holes, the connecting arms pass through the through holes to form a horizontal rotating shaft, the horizontal rotating shaft is rotatably connected to the rotating assembly, so that the ear shells rotate around the horizontal rotating shaft.

[0006] Compared to the prior art, the headphones provided by the present invention utilize earmuff connectors to suspend the earmuffs above the concha, allowing the earmuffs to better wrap around the ears, reducing sound leakage and ensuring sound quality. This also increases air circulation inside the headphones, reduces weight, and reduces pressure on the ears. Furthermore, a rotating assembly is provided within the inner cavity of the concha, and through-holes are provided on the sides of the concha. A horizontal axis formed by a connecting arm passing through the through-hole is rotatably connected to the rotating assembly, allowing the concha to rotate about the horizontal axis. This allows the concha to rotate vertically over a wide range, allowing the user to adjust the angle of the speaker as needed, thereby optimizing the sound transmission path, reducing sound loss during transmission, and ensuring sound quality. Furthermore, the user can adjust the fit of the headphones to their individual ear shape, facial shape, and wearing comfort, ensuring a close fit between the headphones and the ears and further reducing pressure on the ears. This arrangement significantly improves wearing comfort while ensuring sound quality, meeting the user's needs for long-term wear. Furthermore, the design of the earmuffs that can be rotated up and down allows the headphones to be rotated when not in use, reducing their footprint and making them easier to carry and store.

[0007] Furthermore, the connecting arm includes a connecting portion, an arcuate surrounding portion, and a rotating shaft portion. The connecting portion is connected to the headband, the arcuate surrounding portion connects the connecting portion and the rotating shaft portion, and the arcuate surrounding portion extends around the outer circumference of the ear shell. The rotating shaft portion is horizontally arranged and extends into the through hole to form the horizontal rotating shaft. Thus, by designing the connecting portion to connect to the headband, the horizontal rotating shaft formed by the horizontal rotating shaft portion extending into the through hole is rotationally connected to the rotating assembly, and the arcuate surrounding portion is further designed to achieve the connection between the vertically arranged connecting portion and the horizontally arranged rotating shaft portion.

[0008] Furthermore, the rotation assembly includes a detachably assembled fixing block and a shaft fixing plate. The fixing block is fixed to the inner cavity of the auricle. An axial hole is formed between the fixing block and the shaft fixing plate, and the horizontal shaft is rotatably disposed in the axial hole. Thus, the axial hole formed between the fixing block and the shaft fixing plate allows the horizontal shaft to freely rotate within the axial hole, achieving a rotational function. This detachable assembly design allows for precise control of the horizontal shaft's rotational motion, while also facilitating installation and maintenance.

[0009] Furthermore, the fixing block is provided with a first arc groove, and the rotating shaft fixing plate is provided with a second arc groove having the same radius as the first arc groove. The first arc groove and the second arc groove are arranged concentrically to form the shaft hole, and the shaft hole is arranged coaxially with the through hole. Thus, the first arc groove and the second arc groove cooperate to form the shaft hole, and the shaft hole and the through hole are arranged coaxially. The first arc groove and the through hole can achieve positioning of the horizontal rotating shaft, thereby ensuring positioning accuracy.

[0010] Furthermore, the first arc groove is provided with a plurality of open slots, extending along the width of the first arc groove and sequentially distributed along the length of the first arc groove. Thus, the design of the open slots reduces the contact area between the fixed block and the horizontal shaft, thereby reducing friction between the fixed block and the horizontal shaft, making it easier for the horizontal shaft to rotate.

[0011] Furthermore, the ear shell includes an ear shell body and an ear shell cover. The inner cavity is provided in the ear shell body. An opening is provided at one end of the ear shell body away from the earcup. The inner cavity communicates with the outside through the opening. The ear shell cover is used to cover the opening. A plurality of sound-transmitting holes are provided at the other end of the ear shell body. Thus, the above arrangement facilitates maintenance of the components inside the ear shell.

[0012] Furthermore, the earmuffs include an earmuff support and an earcup. The earcup is mounted on the earmuff support. The earmuff support has a first groove, and the ear shell has a second groove corresponding to the first groove. The ends of the earmuff connector respectively engage with the first groove and the second groove. Thus, the hollow and suspended earmuff design increases air circulation inside the headphones, improves wearing comfort and heat dissipation, and creates a light and transparent visual effect and user experience.

[0013] Furthermore, the horizontal rotating shaft is provided with a limiting groove, and the second arc groove is provided with a limiting protrusion corresponding to the limiting groove, and the limiting protrusion is arranged in the limiting groove to limit the horizontal rotating shaft. Thus, by designing the limiting groove and the limiting protrusion, the rotation range of the horizontal rotating shaft is limited, and the axial movement of the horizontal rotating shaft is also limited.

[0014] Furthermore, the headband includes a headband, two sliding brackets, and two arms. The ends of the headband are fixedly connected to the sliding brackets, and one end of the arm is slidably connected to the sliding brackets, and the other end is connected to the connecting arm. Thus, the sliding connection between the arm and the sliding bracket allows the headband to be stretched, so that the headset can adapt to different head circumferences.

[0015] Furthermore, the sound circuit assembly includes a speaker, a main control panel, a microphone stem, several buttons and a charging interface. The speaker, microphone stem, several buttons and charging interface are all electrically connected to the main control panel. The main control panel is arranged in the inner cavity of one of the ear shells, and the microphone stem, several buttons and charging interface are arranged on one of the ear shells.

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0026] See also Figure 1This embodiment provides a headset, including a headband 10, two connecting arms 20, two ear shells 30, two ear cups 40, two ear cup connectors 42, and a sound circuit assembly 50. The ends of the headband 10 are respectively connected to the ear shells 30 via the connecting arms 20, and the ear cups 40 are connected to the ear shells 30 via the ear cup connectors 42. The ear shells 30 have an inner cavity for accommodating the sound circuit assembly 50, and the inner cavity is also provided with a rotating assembly. The side of the ear shells 30 has a through hole 315, and the connecting arms 20 pass through the through hole 315 to form a horizontal rotation axis. The horizontal rotation axis is rotatably connected to the rotating assembly, so that the ear shells 30 rotate about the horizontal rotation axis.

[0027] Thus, the earmuff 40 is suspended above the concha 30 by the earmuff connector 42, so that the earmuff 40 better wraps the ear, reduces sound leakage, and ensures sound quality. At the same time, it can increase air circulation inside the earphone, reduce the weight of the earphone, and reduce the pressure of the earphone on the ear. Then, a rotating assembly is provided in the inner cavity of the concha 30, and a through hole 315 is provided on the side of the concha 30. Then, a horizontal rotation axis formed by the connecting arm 20 passing through the through hole 315 is rotatably connected to the rotating assembly, so that the concha 30 rotates about the horizontal rotation axis, thereby achieving a wide range of rotation in the vertical direction. The user can adjust the angle of the speaker as needed, thereby optimizing the sound transmission path, reducing sound loss during transmission, and ensuring sound quality. At the same time, the user can adjust the earphone according to the shape of the individual ear, face, and wearing comfort, ensuring a close fit between the ear and the ear, and further reducing the pressure of the earphone on the ear. Through the above arrangement, while ensuring sound quality, the user's wearing comfort can be significantly improved, meeting the user's needs for long-term wear. In addition, the ear shell can be rotated up and down so that the earphones can be rotated when not in use to reduce the space they occupy, making it easier for users to carry and store them.

[0028] Please also see Figure 2 and Figure 3 In this embodiment, the headband 10 includes a headband 11, two sliding brackets 12, and two arms 13. The ends of the headband 11 are fixedly connected to the sliding brackets 12, and one end of the arm 13 is slidably connected to the sliding bracket 12, and the other end is connected to the connecting arm 20. Thus, the sliding connection between the arm 13 and the sliding bracket 12 makes the headband 10 stretchable, so that the headset can adapt to different head circumferences.

[0029] Specifically, the sliding bracket 12 is provided with an open slide groove 121, and the open slide groove 121 extends along the length direction of the sliding bracket 12, and the side portion of the head beam 11 is used to be fixedly connected to the sliding bracket 12 to cover the open slide groove 121 to form a hollow slide groove, one end of the support arm 13 extends into the hollow slide groove and is slidably arranged in the hollow slide groove, and the other end of the support arm 13 is connected to the connecting arm 20, and the support arm 13 is provided with a spring piece 131 on one end of the hollow slide groove, and the spring piece 131 is provided with a cylindrical protrusion 1311, and the open slide groove 121 of the sliding bracket 12 is provided with a plurality of third grooves 1211 corresponding to the cylindrical protrusions, and the plurality of third grooves 1211 extend along the width direction of the open slide groove 121 and are sequentially distributed along the length direction of the open slide groove 121, and the cylindrical protrusion 1311 is engaged with one of the third grooves 1211. Thus, after being stretched to a predetermined position, the stretchable headband can be quickly locked by engaging the protrusions and grooves. Preferably, the headband 11 and the sliding bracket 12 are detachably connected by a snap-fit ​​screw lock. Of course, in other alternative embodiments, the headband 11 and the sliding fixed bracket 12 can be integrally formed. Preferably, the spring clip is fixed to the support arm by a snap-fit. Of course, in other alternative embodiments, the spring clip can be welded to the support arm.

[0030] Preferably, the headband 10 further includes a sheath 14 and a sliding bracket cover 15 , wherein the sheath 14 is used to cover the head beam 11 and the sliding bracket 12 , and the sliding bracket cover 15 is covered on the end of the sliding bracket 12 away from the head beam 11 to limit the sheath 14 .

[0031] Please also see Figure 4In this embodiment, the connecting arm 20 includes a connecting portion 21, an arc-shaped surrounding portion 22, and a rotating shaft portion 23. The connecting portion 21 is connected to the headband 10, and the arc-shaped surrounding portion 22 connects the connecting portion 21 and the rotating shaft portion 23. The arc-shaped surrounding portion 22 extends around the outer circumference of the ear shell 30. The rotating shaft portion 23 is horizontally arranged and extends into the through hole 315 to form the horizontal rotating shaft. Thus, by designing the connecting portion 21 to be connected to the headband 10, the horizontal rotating shaft formed by the horizontally arranged rotating shaft portion 23 extending into the through hole 315 is rotationally connected to the rotating assembly, and then by designing the arc-shaped surrounding portion 22, the connection between the vertically arranged connecting portion 21 and the horizontally arranged rotating shaft portion 23 is achieved. Preferably, the horizontal rotating shaft is a horizontal damping rotating shaft. Thus, the design of the damping rotating shaft can enable the ear shell 30 to hover at any angle within the rotation range. Of course, in other alternative embodiments, the contact area or friction coefficient between the horizontal rotating shaft and the shaft hole can be controlled by selecting the materials of the horizontal rotating shaft, the fixing block 314 and the rotating shaft fixing plate 33 or the surface quality requirements of the horizontal rotating shaft, the fixing block 314 and the rotating shaft fixing plate 33, so that the horizontal rotating shaft can rotate when driven by an external force. When there is no external force, the ear shell can be suspended by the friction between the horizontal rotating shaft and the shaft hole.

[0032] Please also see Figure 5 and Figure 6 In this embodiment, the ear shell 30 includes an ear shell body 31 and an ear shell cover 32. The inner cavity 311 is provided within the ear shell body 31. An opening is provided at one end of the ear shell body 31 away from the earcup 40. The inner cavity 311 communicates with the outside through the opening. The ear shell cover 32 is used to cover the opening. A plurality of sound-transmitting holes 312 are provided at the other end of the ear shell body 31. This arrangement facilitates maintenance of the internal components of the ear shell.

[0033] In this embodiment, the earmuff 40 includes an earmuff support 41 and an earcup 43. The earcup 43 is mounted on the earmuff support 41. The earmuff support 41 has a first groove 411, and the ear shell 30 has a second groove 313 corresponding to the first groove. The two ends of the earmuff connector 42 respectively engage with the first groove 411 and the second groove 313. Thus, the hollow and suspended earmuff design increases air circulation inside the earphones, improves wearing comfort and heat dissipation, and creates a light and transparent visual effect and user experience.

[0034] Specifically, the earmuff holder 41 is an annular holder. Its inner surface is recessed inwardly to form a first groove 411. The sidewall of the ear shell body 31 is recessed inwardly to form a second groove 313, corresponding to the first groove 411. The earmuff connector 42 is an arcuate strip, with one end fixedly mounted in the first groove 411 and the other end fixedly mounted in the second groove 313, thereby securing the earmuff holder 41 to the ear shell body 31. The earmuff 42 is sleeved onto the end of the annular holder away from the ear shell body 31. Preferably, one end of the earmuff connector 42 engages with the first groove 411, while the other end engages with the second groove 313 and is secured thereto via screws. This facilitates replacement of the earmuff holder or earmuff. Of course, in other alternative embodiments, the earmuff connector may be integrally formed with the earmuff holder.

[0035] Preferably, the earmuffs 43 are silicone earmuffs. Thus, the earmuffs 43 are made of silicone, which can disperse the pressure on the head, is durable and does not deform, and is soft, delicate and elastic when worn. It can provide a comfortable wearing experience while reducing lateral pressure on the ear, avoiding discomfort caused by long-term wearing of TWS and sound distortion of OWS. Of course, in other replaceable embodiments, the earmuffs 43 may be leather earmuffs or memory foam earmuffs. Preferably, the cross-sectional shape of the earmuff bracket 41 is elliptical, so that the elliptical earmuff contour better fits the shape of the ear. Of course, in other replaceable embodiments, the cross-sectional shape of the earmuff bracket 41 is not limited to elliptical, and may be circular.

[0036] Please also see Figure 7 In this embodiment, the rotating assembly includes a detachable fixed block 314 and a rotating shaft fixing plate 33. The fixed block 314 is fixed to the inner cavity of the ear shell 30. An axial hole is formed between the fixed block 314 and the rotating shaft fixing plate 33, and the horizontal rotating shaft is rotatably arranged in the axial hole. Thus, by forming an axial hole between the fixed block and the rotating shaft fixing plate, the horizontal rotating shaft can rotate freely in the axial hole to realize the rotation function. Through the detachable assembly design, the precise control of the rotational movement of the horizontal rotating shaft can be achieved, and it is convenient for installation and maintenance. Preferably, the fixed block is integrally formed with the ear shell body. Of course, in other alternative embodiments, the fixed block and the ear shell body can be designed as separate bodies, and the fixed block can be detachably installed in the ear shell body by means of screws or snaps.

[0037] Specifically, the fixing block 314 is provided with a first circular arc groove 3141, and the rotating shaft fixing plate 33 is provided with a second circular arc groove 331 having the same radius as the first circular arc groove 3141. The first circular arc groove 3141 and the second circular arc groove 331 are arranged concentrically and form the axial hole, and the axial hole is arranged coaxially with the through hole 315. Thus, the first circular arc groove 3141 and the second circular arc groove 331 cooperate to form the axial hole, and the axial hole is arranged coaxially with the through hole. The first circular arc groove 3141 and the through hole 315 can be used to position the horizontal rotating shaft, ensuring the accuracy of positioning. Preferably, the rotating shaft fixing plate 33 is mounted on the fixing block 314 by screws. Of course, in other alternative embodiments, the rotating shaft fixing plate 33 and the fixing block 314 are fixedly connected by a buckle. Preferably, the first circular arc groove 3141 and the second circular arc groove 331 are both semi-circular arc grooves. Of course, in other alternative embodiments, the first arc groove 3141 and the second arc groove 331 are not limited to semi-circular arc grooves, and the first arc groove and the second arc groove can form a circular shaft hole.

[0038] Preferably, the first arc groove 3141 is provided with a plurality of open grooves 31411, which extend along the width direction of the first arc groove 3141 and are sequentially distributed along the length direction of the first arc groove 3141. Thus, the design of the open grooves reduces the contact area between the fixed block 314 and the horizontal shaft, thereby reducing the friction between the fixed block 314 and the horizontal shaft, making it easier for the horizontal shaft to rotate.

[0039] In this embodiment, a limiting groove is provided on the horizontal rotating shaft, and a limiting protrusion corresponding to the limiting groove is provided on the second circular arc groove. The limiting protrusion is arranged in the limiting groove to limit the horizontal rotating shaft. Thus, by designing the limiting groove and the limiting protrusion, the rotation range of the horizontal rotating shaft is limited, and the axial movement of the horizontal rotating shaft is limited at the same time. Specifically, the cross-sectional shape of the limiting groove is a fan-shaped ring, and the limiting groove extends along the length direction of the horizontal rotating shaft; the cross-sectional shape of the limiting protrusion is a fan-shaped ring, and the limiting protrusion extends along the length direction of the second circular arc groove, and the central angle of the fan-shaped limiting groove is greater than the central angle of the fan-shaped limiting protrusion. Preferably, the angular difference between the central angle of the fan-shaped limiting groove and the central angle of the fan-shaped limiting protrusion is 45°. Thus, the ear shell can rotate up and down within a range of 45°. Of course, in other alternative embodiments, the angle difference between the central angle of the fan-shaped limiting groove and the central angle of the fan-shaped limiting protrusion is not limited to 45°, and can be any other angle such as 30°, 60° or 90°.

[0040] In this embodiment, the sound circuit assembly 50 includes a speaker 51, a main control board 52, a microphone stem 53, several buttons 54 and a charging interface 55. The speaker 51, microphone stem 53, several buttons 54 and charging interface 55 are all electrically connected to the main control board 52. The main control board 52 is arranged in the inner cavity of one of the ear shells, and the microphone stem 53, several buttons 54 and charging interface 55 are arranged on one of the ear shells. Preferably, the microphone stem is detachably arranged on the ear shell in a plug-in manner, thereby facilitating the storage of the earphones. It should be noted that the sound circuit assembly is used for sound playback and collection. Its specific structure and the specific connection relationship between the components are all existing technologies, so they will not be repeated here.

[0041] Preferably, the sound circuit assembly 50 further includes an LED light board, which is disposed in the inner cavities of both ear shells. The ear shells further include a light-transmitting ring that surrounds the ear shell cover and, together with the ear shell cover, covers the opening. Light generated by the LED light board is diffused through the light-transmitting ring, thereby providing a unique visual effect.

[0042] When wearing, the stretchable headband is adjusted to adapt to the user's head circumference, and the angle of the ear shells is adjusted up and down to adapt to the user's ear shape and face shape, thereby ensuring wearing comfort; when not wearing, the ear shells can be rotated to adapt to the state of hanging around the neck or storing.

[0043] Compared to the prior art, the headphones provided by the present invention utilize earmuff connectors to suspend the earmuffs above the concha, allowing the earmuffs to better wrap around the ears, reducing sound leakage and ensuring sound quality. This also increases air circulation inside the headphones, reduces weight, and reduces pressure on the ears. Furthermore, a rotating assembly is provided within the inner cavity of the concha, and through-holes are provided on the sides of the concha. A horizontal axis formed by a connecting arm passing through the through-hole is rotatably connected to the rotating assembly, allowing the concha to rotate about the horizontal axis. This allows the concha to rotate vertically over a wide range, allowing the user to adjust the angle of the speaker as needed, thereby optimizing the sound transmission path, reducing sound loss during transmission, and ensuring sound quality. Furthermore, the user can adjust the fit of the headphones to their individual ear shape, facial shape, and wearing comfort, ensuring a close fit between the headphones and the ears and further reducing pressure on the ears. This arrangement significantly improves wearing comfort while ensuring sound quality, meeting the user's needs for long-term wear. Furthermore, the design of the earmuffs that can be rotated up and down allows the headphones to be rotated when not in use, reducing their footprint and making them easier to carry and store.
