Description

Technical Field

[0001] This invention relates to the field of wearable device technology, and in particular to a headset. Background Technology

[0002] As people's living standards improve, headphones are becoming increasingly popular due to their comfortable fit and superior user experience.

[0003] However, since the earcups of over-ear headphones come into contact with the user's ears, after wearing them for a period of time, the ears may feel pressured or stuffy. The over-ear headphones in the relevant technology require the user to remove the headphones from their head to relieve the ear discomfort, and then put them back on after the discomfort is relieved, which is inconvenient and affects the user experience. Summary of the Invention

[0004] The main objective of this invention is to provide a type of over-ear headphone that can alleviate ear discomfort without requiring the user to remove the headphones, is easy to operate, and improves the user experience.

[0005] To achieve the above objectives, the present invention provides a headset comprising:

[0006] Headband;

[0007] Two earphone bodies are movably connected to both ends of the headband; and

[0008] Two adjustment mechanisms, each of which is connected to one end of the headband and one of the earphone bodies;

[0009] The earphone body can rotate relative to the headband under the action of an external force to switch between a first position and a second position:

[0010] When the earphone body is rotated to the first position, the earphone body and the headband are fixed relative to each other for fitting with the user's ear;

[0011] When the earphone body is rotated to the second position, the adjustment mechanism can drive the earphone body to move along its rotation axis away from the user's ear.

[0012] In one embodiment of this application, the earphone body is disposed inside the headband, and the earphone body is provided with an avoidance groove for avoiding the headband on the side near the headband.

[0013] When the headphone body is rotated to the first position, the clearance groove is misaligned with the headband, and the outer side wall of the headphone body abuts against and limits the headband.

[0014] When the earphone body is rotated to the second position, the clearance groove is aligned with the headband, and the adjustment mechanism can drive the earphone body to move away from the user's ear relative to the headband.

[0015] In one embodiment of this application, the earphone body is cylindrical, and the end of the headband is located at the axial outer end of the earphone body; the clearance groove is formed on the axial outer end face of the earphone body and extends radially outward from the rotation center of the earphone body to the outer peripheral wall of the earphone body.

[0016] In one embodiment of this application, the headband has a connecting shaft extending along the rotation axis of the headphone body. The headphone body includes a headphone shell and a guide sleeve disposed in the headphone shell. The connecting shaft is rotatably fitted into the guide sleeve.

[0017] When the earphone body is rotated to the second position, the adjustment mechanism can drive the guide sleeve and the connecting shaft to move relative to each other along the axial direction.

[0018] In one embodiment of this application, the adjustment mechanism is disposed inside the guide sleeve to connect the connecting shaft and the earphone shell respectively.

[0019] In one embodiment of this application, the adjustment mechanism includes:

[0020] A sliding block is rotatably disposed outside the connecting shaft and axially limited with the connecting shaft; the sliding block is circumferentially limited with the guide sleeve and can slide axially along the guide sleeve; and

[0021] An elastic element is disposed within the guide sleeve to connect the sliding block and the earphone shell.

[0022] In one embodiment of this application, the outer peripheral wall of the connecting shaft is provided with a limiting boss, and the sliding block is provided with an annular groove, wherein the limiting boss is limited and fitted within the annular groove.

[0023] In one embodiment of this application, the inner wall of the guide sleeve is provided with a first limiting rib, and the sliding block is provided with a first limiting groove extending along the axial direction. The first limiting rib is slidably engaged in the first limiting groove to limit the relative rotation between the sliding block and the guide sleeve.

[0024] In one embodiment of this application, the sliding block has a cylindrical structure, the inner wall of the guide sleeve is a cylindrical groove, and the outer peripheral wall of the sliding block slides in conjunction with the inner peripheral wall of the guide sleeve.

[0025] In one embodiment of this application, the earphone body is provided with two second limiting ribs for resisting and limiting the headband at a first position and a second position, respectively.

[0026] In this invention's over-ear headphones, the headphone body is movably connected to the end of the headband. An adjustment mechanism connects the headphone body and the headband, allowing the headphone body to rotate relative to the headband between a first and a second position under external force. When the headphone body rotates to the first position, it is relatively fixed to the headband to fit the user's ear. When the headphone body rotates to the second position, the adjustment mechanism drives the headphone body to move along its rotation axis away from the user's ear. This allows switching between a wearing position (fitting with the user's ear) and a released position (detached from the user's ear). During use, the user does not need to remove the headband; simply rotating the headphone body removes it from the ear to alleviate discomfort. This achieves simple operation and improves the user experience. Attached Figure Description

[0043] This invention proposes a type of over-ear headphone that aims to alleviate ear discomfort and enable long-term wear without removing the headphone structure, thereby improving the user experience.

[0044] In embodiments of the present invention, such as Figures 1 to 5 As shown, the headset includes a headband 100, two earphone bodies 200, and two adjustment mechanisms 300.

[0045] Two earphone bodies 200 are movably connected to both ends of the headband 100; each adjustment mechanism 300 is correspondingly connected to one earphone body 200 and one end of the headband 100.

[0046] The headphone body 200 can rotate relative to the headband 100 under external force to switch between a first position and a second position:

[0047] When the headphone body 200 is rotated to the first position, the headphone body 200 is fixed relative to the headband 100 for use with the user's ear;

[0048] When the headphone body 200 is rotated to the second position, the adjustment mechanism 300 can drive the headphone body 200 to move along its rotation axis away from the user's ear.

[0049] The headband 100 is worn on the user's head or neck. Two earphone bodies 200 are respectively located at both ends of the headband 100 to correspond to the user's ears. The earphone bodies 200 may contain built-in sound-producing components; their specific structure can refer to conventional earphone structures and will not be described in detail here. Correspondingly, the headband 100 may be a clamp structure, etc., and its specific structure can refer to conventional headband structures and will not be described in detail here. In application, since the two earphone bodies 200 are in direct contact with the user's ears, sometimes, to ensure sound sealing, the earphone bodies 200 exert a certain resistance on the user's ears. Therefore, after a period of use, the user's ears may experience discomfort. Based on this, in this embodiment, the earphone bodies 200 are movably connected to the ends of the headband 100. The earphone bodies 200 can rotate relative to the headband 100 under external force. An adjustment mechanism 300 connects the earphone bodies 200 and the headband 100. When the earphone bodies 200 rotate to the first position, the earphone bodies 200 and the headband 100 are relatively fixed, and the earphone bodies 200 are in a wearing position that aligns with the user's ears. When the earphone bodies 200 rotate to the second position, the adjustment mechanism 300 can drive the earphone bodies 200 to move along their rotation axis to a release position away from the user's ears. This allows switching between a wearing position that aligns with the user's ears and a release position that is not aligned with the user's ears, enabling the user to adjust the position of the earphone bodies 200 according to their needs.

[0050] When a user normally uses the headphones, the headband 100 is worn on the user's head, and the headphone body 200 is in the wearing position, contacting and abutting against the user's ears. At this time, the headphone body 200 is in the first position relative to the headband 100. Figures 1 to 3 ;

[0051] After a period of use, if the user experiences ear discomfort, the user can rotate the earphone body 200 to the second position. The adjustment mechanism 300 will then drive the earphone body 200 along its rotation axis in a direction away from the user's ear until it is disengaged from the user's ear, thus releasing the force applied to the user's ear and alleviating discomfort. Figures 4 to 6 ;

[0052] Once the discomfort subsides, the user can pull the earphone body 200 back and rotate it to the first position for wearing, thus fixing the earphone body 200 relative to the headband 100 for continued normal use. Figures 1 to 3 .

[0053] In this way, users can adjust the position of the headphone body 200 according to their actual usage needs. It should be noted that, in the use of the headphones provided in this embodiment, users do not need to remove the headband 100 when adjusting the position of the headphone body 200. They only need to adjust the distance between the headphone body 200 and the user's ear. The operation is simple and improves the convenience of use.

[0054] In practical applications, the pressure on the earphone body 200 can be relieved as long as it can detach from the user's ear. When the earphone body 200 rotates to the second position relative to the headband 100, the adjustment mechanism 300 can drive the earphone body 200 to move along the rotation axis of the earphone body 200 to detach from the user's ear. It can be understood that the rotation axis of the earphone body 200 forms an angle with the extension direction of the headband 100. This angle can be perpendicular to the extension direction of the headband 100 (equivalent to the left-right or front-back direction of the user's head), or it can be tilted to the extension direction of the headband 100 (equivalent to the upper left / lower left, upper right / lower right, etc. of the user's head). For ease of user operation, as an example, the earphone body 200 can rotate along its own central axis. In this case, the rotation axis of the earphone body 200 is perpendicular to the extension direction of the headband 100, and the earphone body 200 moves in the left-right direction of the user's head, which is more suitable for human usage habits and allows for faster wearing or removal from the user's ear.

[0055] It should be noted that in this embodiment, the earphone body 200 and the headband 100 can both rotate and slide relative to each other. It is understood that the adjustment mechanism 300 connects the ends of the earphone body 200 and the headband 100. When the earphone body 200 is in the first position, the earphone body 200 and the headband 100 are relatively fixed, meaning the connection between them is locked, and the adjustment mechanism 300 does not need to provide a driving function. When the earphone body 200 rotates to the second position, the connection between them is unlocked, allowing relative movement. At this point, the adjustment mechanism 300 can drive the earphone body 200 to move. The specific structure of the adjustment mechanism 300 in this embodiment can be determined according to actual conditions, such as an elastic structure, a lead screw-slider structure, a wedge block structure, or a threaded structure, etc. Its specific structure is not limited here, as long as it can drive the earphone body 200 away from the user's ear.

[0056] In the over-ear headphones of this invention, the headphone body 200 is movably connected to the end of the headband 100. An adjustment mechanism 300 connects the headphone body 200 and the headband 100, allowing the headphone body 200 to rotate relative to the headband 100 between a first position and a second position under external force. When the headphone body 200 rotates to the first position, it is relatively fixed to the headband 100 to fit the user's ear. When the headphone body 200 rotates to the second position, the adjustment mechanism 300 drives the headphone body 200 to move along its rotation axis away from the user's ear. This allows switching between a wearing position (fitting the user's ear) and a released position (detached from the user's ear). During use, the user does not need to remove the headband 100; simply rotating the headphone body 200 removes it from the user's ear to alleviate discomfort. This achieves the effects of simple operation and improved user experience.

[0057] In one embodiment of this application, please refer to Figures 1 to 6 The earphone body 200 is located inside the headband 100. The earphone body 200 has a clearance groove 201 on the side near the headband 100 to avoid the headband 100. When the earphone body 200 is rotated to the first position, the clearance groove 201 is misaligned with the headband 100, and the outer wall of the earphone body 200 abuts against and limits the headband 100. When the earphone body 200 is rotated to the second position, the clearance groove 201 is aligned with the headband 100, and the adjustment mechanism 300 can drive the earphone body 200 to move away from the user's ear relative to the headband 100.

[0058] In this embodiment, by placing the earphone body 200 inside the headband 100 and providing an abutment groove 201 on the outer wall of the earphone body 200, when the earphone body 200 rotates relative to the headband 100 under external force, the abutment groove 201 can rotate together. Thus, when the earphone body 200 rotates to the first position, the headband 100 and the abutment groove 201 are offset. At this time, the headband 100 is still located outside the earphone body 200, and the headband 100 and the outer wall of the earphone body 200 abut and limit each other, making the earphone body 200 and the headband 100 relatively fixed, and the earphone body 200 is positioned close to the user's ear. When the headphone body 200 rotates to the second position, it causes the clearance groove 201 to be aligned with the headband 100. At this time, the clearance groove 201 can provide space for the headband 100 to move, that is, the headband 100 and the headphone body 200 can move relative to each other. Under the driving action of the adjustment mechanism 300, the headphone body 200 and the headband 100 move towards each other, thereby realizing that the headphone body 200 moves away from the user's ear to the release position.

[0059] In practical applications, as an example, the adjustment mechanism 300 can always provide a driving force to the headphone body 200 toward the direction away from the user's ear. When the headphone body 200 is in the first position relative to the headband 100, due to the mutual abutment between the outer wall of the headphone body 200 and the headband 100, the adjustment mechanism 300 cannot drive the headphone body 200 to move relative to the headband 100. In this case, the adjustment mechanism 300 can strengthen the abutment between the headphone body 200 and the headband 100, making the relative fixation between the headphone body 200 and the headband 100 more reliable, thereby preventing the headphone body 200 from shaking and falling off during normal use, and ensuring the reliability of user use. When the headphone body 200 is rotated to the second position, since the clearance groove 201 of the headphone body 200 is aligned with the headband 100, the adjustment mechanism 300 can drive the headphone body 200 to move relative to the headband 100. At this time, the clearance groove 201 can accommodate and avoid the headband 100, and the headphone body 200 can move smoothly toward the outside of the headband 100 to remove itself from the user's ear and relieve discomfort.

[0060] Understandably, the shape and structure of the clearance groove 201 can be determined according to the actual situation. For example, it can be a regular strip groove, rectangular groove, or cylindrical groove, or it can be other irregularly shaped groove structures. The specific groove structure is not limited here, as long as it can allow the headband 100 to pass through smoothly.

[0061] In one embodiment of this application, please refer to Figures 1 to 6The headphone body 200 is cylindrical, and the end of the headband 100 is located at the axial outer end of the headphone body 200. The clearance groove 201 is opened on the axial outer end face of the headphone body 200 and extends radially outward from the rotation center of the headphone body 200 to the outer peripheral wall of the headphone body 200, so as to avoid the headband 100 in the second position.

[0062] This embodiment illustrates the structure of the clearance groove 201. As can be understood, the earphone body 200 has a cylindrical structure, and the axial outer end face of the earphone body 200 is connected to the end of the headband 100. The connection point between the earphone body 200 and the headband 100 is the rotation center position of the headband 100. By opening the clearance groove 201 on the axial outer end face of the earphone body 200, and extending the clearance groove 201 radially outward from the rotation center of the earphone body 200 to the outer peripheral wall of the earphone body 200, the clearance groove 201 can smoothly accommodate the headband 100 when the earphone body 200 rotates to the second position, thus playing a clearance role for the headband 100.

[0063] It should be noted that the clearance groove 201 in this embodiment has a certain depth in the axial direction of the earphone body 200, so that the earphone body 200 can have enough room to move relative to the headband 100, and can smoothly detach from the user's ear, thereby achieving a better effect of relieving discomfort.

[0064] As an example, the clearance groove 201 can be a rectangular groove. The width of the clearance groove 201 on the axial end face of the headphone body 200 can be slightly larger than the outer diameter of the headband 100, so that the headband 100 can smoothly enter the clearance groove 201. At the same time, the clearance groove 201 can play a certain limiting role for the headband 100.

[0065] Furthermore, the headphone body 200 is provided with two second limiting ribs 230 for resisting and limiting the headband 100 in the first position and the second position respectively.

[0066] In this embodiment, two second limiting ribs 230 are provided on the earphone body 200, and the two second limiting ribs 230 abut against the headband 100 respectively, thereby achieving the positioning of the relative position between the earphone body 200 and the headband 100. It can be understood that a second limiting rib 230 can be provided on one side of the clearance groove 201 to limit the headband 100, so that when the earphone body 200 rotates to the second position, the headband 100 can smoothly align with the clearance groove 201, improving adjustment efficiency.

[0067] Understandably, the placement of the two second limiting ribs 230 determines the rotation angle of the earphone body 200. In practical applications, the rotation angle of the earphone body 200 cannot be too large or too small. If it is too small, there is a risk of accidental touch (i.e., the user may accidentally rotate the earphone body 200, causing it to detach from the ear during normal use). If it is too large, it will cause inconvenience for the user. Based on this, as an example, the two second limiting ribs 230 can be set vertically, so that the rotation angle of the earphone body 200 between the first position and the second position is 90°. This can prevent the risk of accidental touch while facilitating user operation and further improving the user experience.

[0068] In one embodiment of this application, please refer to Figures 2 to 7 The headband 100 has a connecting shaft 110 extending along the rotation axis of the headphone body 200 at its end. The headphone body 200 includes a headphone shell 210 and a guide sleeve 220 disposed in the headphone shell 210. The connecting shaft 110 is rotatably fitted in the guide sleeve 220. When the headphone body 200 is rotated to the second position, the adjustment mechanism 300 can drive the guide sleeve 220 and the connecting shaft 110 to move relative to each other along the axial direction.

[0069] This embodiment illustrates the connection structure between the headband 100 and the earphone body 200. A connecting shaft 110 is provided at the end of the headband 100, and a guide sleeve 220 is provided on the earphone shell 210 of the earphone body 200. The guide sleeve 220 is fitted onto the connecting shaft 110, and the connecting shaft 110 and the guide sleeve 220 are rotatably engaged, realizing the rotatable connection function between the earphone body 200 and the headband 100. An adjustment mechanism 300 connects the connecting shaft 110 and the earphone shell 210, so that when the earphone body 200 rotates to the second position, the adjustment mechanism 300 can drive the connecting shaft 110 and the guide sleeve 220 to move relative to each other in the axial direction, realizing the function of the earphone body 200 moving outward relative to the headband 100.

[0070] Understandably, the earphone shell 210 serves to install and fix the sound-generating components. Earphone pads 240 can be provided on the opposite sidewalls of the two earphone shells 210 to increase user comfort. Optionally, the earphone shell 210 includes an earphone outer shell 211 and an earphone outer cover 212. The earphone outer cover 212 and the earphone pads 240 are respectively disposed on both sides of the earphone outer shell 211, and the clearance groove 201 extends from the earphone outer cover 212 into the interior of the earphone outer shell 211.

[0071] Furthermore, the adjustment mechanism 300 is located inside the guide sleeve 220 to connect the connecting shaft 110 and the earphone shell 210 respectively.

[0072] Understandably, the connecting shaft 110 and the guide sleeve 220 can rotate relative to each other in the circumferential direction and move relative to each other in the axial direction. As an example, the guide sleeve 220 has an axially extending cylindrical groove inside, and the connecting shaft 110 is located within the cylindrical groove. The adjusting mechanism 300 connects the connecting shaft 110 and the earphone shell 210, creating opposing tension between them, thereby preventing the connecting shaft 110 from detaching from the guide sleeve 220. Furthermore, by placing the adjusting mechanism 300 within the guide sleeve 220, no additional space is required, simplifying the structural layout.

[0073] In one embodiment of this application, please refer to Figures 2 to 7 The adjustment mechanism 300 includes a sliding block 310 and an elastic element 320. The sliding block 310 is rotatably disposed outside the connecting shaft 110 and is axially limited with the connecting shaft 110. The sliding block 310 is circumferentially limited with the guide sleeve 220 and can slide axially along the guide sleeve 220. The elastic element 320 is disposed inside the guide sleeve 220 and connects the sliding block 310 and the earphone shell 210 to provide an elastic force for the earphone body 200 to move away from the user's ear.

[0074] This embodiment illustrates the structure of the adjustment mechanism 300. The adjustment mechanism 300 includes a sliding block 310 and an elastic element 320 connected to each other. The sliding block 310 is connected to the connecting shaft 110, and the elastic element 320 is connected to the earphone shell 210. The elastic element 320 can generate opposing pulling forces on the sliding block 310 and the earphone shell 210. Specifically, the sliding block 310 is axially upper-limited connected to the connecting shaft 110, and the sliding block 310 and the guide sleeve 220 can slide relative to each other axially. Thus, when the earphone body 200 rotates to the second position, the elastic element 320 can drive the earphone shell 210 to move axially relative to the connecting shaft 110, thereby realizing the function of driving the earphone body 200 to move outward. Furthermore, the sliding block 310 and the guide sleeve 220 are circumferentially limited, and the sliding block 310 and the connecting shaft 110 can rotate circumferentially, thereby realizing the function of the headband 100 and the earphone body 200 being able to rotate relative to each other.

[0075] In addition, the sliding block 310 and the guide sleeve 220 are circumferentially limited, so when the guide sleeve 220 rotates, the sliding block 310 will rotate along with it. Then the elastic element 320 connecting the sliding block 310 and the earphone shell 210 will also rotate. At this time, the elastic element 320, the sliding block 310 and the earphone shell 210 will rotate synchronously, so the elastic element 320 will not be subjected to torsional force, ensuring the reliability of the elastic element 320 and extending its service life.

[0076] As an example, the elastic element 320 can be a tension spring.

[0077] In one embodiment of this application, please refer to Figures 2 to 7The outer peripheral wall of the connecting shaft 110 is provided with a limiting boss 111, and the sliding block 310 is provided with an annular groove 311. The limiting boss 111 is limited and fitted in the annular groove 311.

[0078] In this embodiment, by providing a limiting boss 111 on the outer peripheral wall of the connecting shaft 110 and an annular groove 311 in the sliding block 310, the limiting boss 111 is limited and fitted in the annular groove 311, thereby realizing the function of axially limiting the sliding block 310 and the connecting shaft 110 and being able to rotate circumferentially.

[0079] As an example, the limiting boss 111 can be an annular boss that is adapted to the annular slot 311.

[0080] In one embodiment of this application, please refer to Figures 2 to 7 The inner wall of the guide sleeve 220 is provided with a first limiting rib 221, and the sliding block 310 is provided with a first limiting groove 312 extending along the axial direction. The first limiting rib 221 is slidably engaged in the first limiting groove 312 to limit the relative rotation between the sliding block 310 and the guide sleeve 220.

[0081] In this embodiment, a first limiting rib 221 is provided on the inner wall of the guide sleeve 220, and a first limiting groove 312 is provided on the outer side of the sliding block 310. The first limiting rib 221 and the first limiting groove 312 are slidably engaged, realizing the function of circumferentially limiting the sliding block 310 and the guide sleeve 220 while allowing axial movement. In addition, the limiting engagement of the first limiting groove 312 and the first limiting rib 221 plays a guiding role in the relative movement of the sliding block 310 and the guide sleeve 220, improving the reliability of the relative movement between the earphone body 200 and the headband 100.

[0082] As an example, the sliding block 310 has a cylindrical structure, the inner wall of the guide sleeve 220 is a cylindrical groove, and the outer peripheral wall of the sliding block 310 slides in contact with the inner peripheral wall of the guide sleeve 220. This configuration makes the cooperation between the sliding block 310 and the guide sleeve 220 more reliable.

[0083] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
