Description

Technical Field

[0001] The invention belongs to the technical field of earphones, and in particular relates to a headset. Background Art

[0002] This section merely provides background information related to the present disclosure and is not necessarily prior art.

[0003] Currently, the ear shells of headphones cannot move on the headband or can only move up and down, and cannot be opened outward, resulting in the need to open the headband a large distance to bring it to the right position when worn. The headband will produce a large deformation during the opening process, which can easily cause stress concentration in the middle of the headband and cause breakage, affecting the service life. In addition, during use, the user's ears will have a strong sense of pressure after wearing them for a long time. If the ears need to rest and relax, the entire headset needs to be removed, and the headband needs to be opened again when used, which is inconvenient to use. Summary of the invention

[0004] The purpose of the present invention is to at least solve the problem of inconvenience in wearing headphones in the prior art. This purpose is achieved through the following technical solutions:

[0005] The present invention provides a headset, comprising:

[0006] Head wear;

[0007] two ear shells;

[0008] A connecting structure, wherein the two ear shells are movably connected to the two ends of the headband through the connecting structure respectively, and the connecting structure includes a limiting part and an operating part. The ear shells and the headband are limited by the limiting part, and the operating part locks and unlocks the limit of the ear shells and the headband under the action of an external force. In the locked state, the ear shells and the headband are limited by the limiting part to limit the movement of the ear shells relative to the headband; in the unlocked state, the operating part releases the limit of the ear shells and the headband, so that the ear shells can move in a direction away from the ears while remaining connected to the headband.

[0009] According to the headset of the embodiment of the present invention, the connection structure can only move the ear shell of the headset, thereby reducing the deformation of the middle part of the headset, reducing stress concentration, and extending the service life of the headset. In addition, during use, the user's ears will have a strong sense of pressure after wearing it for a long time. When the headset is always worn on the head, the ear shell and the headset can be unlocked through the operating part to move the ear shell away from the ear without taking off the entire headset, which is more convenient to use and allows the user's ears to rest and relax.

[0010] In some embodiments of the present invention, the connection structure further includes a rotating shaft, the rotating shaft is disposed at the earphone housing end, and the earphone housing is rotatably connected to the headband through the rotating shaft.

[0011] In some embodiments of the present invention, the operating part is sleeved outside the rotating shaft along the axial direction of the rotating shaft, and the limiting part is disposed on the operating part.

[0012] In some embodiments of the present invention, a limiting groove and a first limiting protrusion are provided on the rotating shaft;

[0013] The limiting part includes a first circumferential locking part and an axial locking part provided on the inner surface of the operating part. The axial locking part is in limiting cooperation with the first limiting protrusion to limit the axial movement of the earphone housing relative to the headband. In the locked state, the first circumferential locking part is in limiting cooperation with the limiting groove to limit the circumferential movement of the earphone housing relative to the headband. In the unlocked state, the operating part separates the first circumferential locking part from the limiting groove so that the earphone housing can rotate away from the ear.

[0014] In some embodiments of the present invention, a second limiting protrusion is provided on the side of the headband facing the operating part, and a second circumferential locking part in limiting cooperation with the second limiting protrusion is provided on the outer surface of the operating part.

[0015] In some embodiments of the present invention, the headset further includes a first elastic member, and the first elastic member is clamped between the operating part and the rotating shaft.

[0016] In some embodiments of the present invention, a receiving groove is provided on the end surface of the rotating shaft that cooperates with the operating part, and a part of the first elastic member is located in the receiving groove.

[0017] In some embodiments of the present invention, the headset further includes a second elastic member connected to the headband. Both ends of the second elastic member are connected to the headband, and the middle region of the second elastic member protrudes toward the rotating shaft and abuts against the rotating shaft. In the locked state, the second elastic member has a preset deformation amount.

[0018] In some embodiments of the present invention, at least one end of the rotating shaft is further provided with a first axial mounting groove and a second axial mounting groove. The first circumferential locking part slides along the first axial mounting groove to separate from it and then rotates so that the first circumferential locking part is in limiting cooperation with the limiting groove. The axial locking part slides along the second axial mounting groove to separate from it and then rotates so that the axial locking part is in limiting cooperation with the first limiting protrusion.

[0019] In some embodiments of the present invention, the first elastic member is a columnar spring and the second elastic member is a shrapnel. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be completely conveyed to those skilled in the art.

[0039] It should be understood that the terms used herein are for the purpose of describing specific example embodiments only and are not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" as used herein may also include the plural forms. The terms "include", "comprise", "contain" and "have" are inclusive and thus specify the presence of the stated features, steps, operations, elements and / or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof.

[0040] Although the terms first, second, third, etc. may be used in this document to describe multiple elements, components, regions, layers and / or segments, these elements, components, regions, layers and / or segments should not be limited by these terms. These terms may only be used to distinguish one element, component, region, layer or segment from another region, layer or segment. Unless the context clearly indicates otherwise, terms such as "first" and "second" and other numerical terms used herein do not imply an order or sequence. Therefore, the first element, component, region, layer or segment discussed below may be referred to as the second element, component, region, layer or segment without departing from the teachings of the example embodiments.

[0041] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature shown in the figure relative to another element or feature. These relative terms, such as "inner part", "outer part", "inner side", "outer side", "lower", "below", "upper", "above", etc., are intended to include different orientations of the device in use or operation other than the orientations depicted in the figure. For example, if the device in the figure is flipped, an element described as "below" or "beneath" another element or feature will then be oriented as "above" or "over" the other element or feature. Thus, the exemplary term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text are interpreted accordingly.

[0042] As Figures 1 to 11 shown, a headset according to an embodiment of the present invention includes a headband 1, two ear cups 2, and a connecting structure 3. The two ear cups 2 are respectively movably connected to the headband 1 through the connecting structure 3. The connecting structure 3 includes a limiting portion and an operating portion 32. The ear cup 2 and the headband 1 are in limiting cooperation through the limiting portion. The operating portion 32 locks and unlocks the limitation between the ear cup 2 and the headband 1 under an external force. In the locked state, the ear cup 2 and the headband 1 are in limiting cooperation through the limiting portion to limit the movement of the ear cup 2 relative to the headband 1. In the unlocked state, the operating portion 32 releases the limitation between the ear cup 2 and the headband 1, so that while the ear cup 2 remains connected to the headband 1, it can move away from the ear. Through the connecting structure 3, only the ear cup 2 part of the headset can move, thereby reducing the deformation of the middle position of the headband 1, reducing stress concentration, and extending the service life of the headset. In addition, during use, after the user wears the headset for a long time, there will be a strong sense of compression on the ears. While the headband 1 is always worn on the head, by operating the operating portion 32 to unlock the limitation between the ear cup 2 and the headband 1 and moving the ear cup 2 away from the ear part, there is no need to remove the entire headset, which is more convenient to use and enables the user's ears to rest and relax.

[0043] The headset includes two ear cups 2. Setting at least one of the two ear cups 2 to be movably connected to the headband 1 through the connecting structure 3 includes two cases: First, any one of the two ear cups 2 is set to be movably connected to the headband 1 through the connecting structure 3, which can be the ear cup 2 corresponding to the left ear or the ear cup 2 corresponding to the right ear. Second, both of the two ear cups 2 are set to be movably connected to the headband 1 through the connecting structure 3.

[0044] In some embodiments of the present invention, the switching of the connection structure 3 between the locked state and the unlocked state can be achieved by means of a button or a knob, etc., or by the user directly applying a force to the ear shell 2 and / or the headband 1. The ear shell 2 can move away from the ear in the unlocked state of the connection structure 3, which can be sliding away from the ear or rotating away from the ear. In one embodiment, the ear shell 2 can rotate away from the ear in the unlocked state of the connection structure 3. Specifically, as Figures 1 to 7 and Figure 9 shown, the connection structure 3 includes a rotating shaft 31, and the rotating shaft 31 is arranged at the end of the ear shell 2. The ear shell 2 is rotatably connected to the headband 1 through the rotating shaft 31. In the locked state, the relative positions among the headband 1, the rotating shaft 31, and the ear shell 2 are fixed, and the user can use it normally. In the unlocked state, since the operating part releases the limit between the ear shell and the headband, and the headband is rotatably connected to the rotating shaft 31, the user can apply a force to the ear shell 2 with the headband 1 as a reference point so that the ear shell 2 and the rotating shaft 31 can rotate away from the ear synchronously, and the user's ear can get rest and relaxation.

[0045] In other embodiments, the connection structure 3 includes a rotating shaft 31, and the rotating shaft 31 is arranged at the end of the headband 1. The ear shell 2 is rotatably connected to the headband 1 through the rotating shaft 31. In the locked state, the relative positions among the headband 1, the rotating shaft 31, and the ear shell 2 are fixed, and the user can use it normally. In the unlocked state, since the operating part releases the limit between the ear shell and the headband, and the rotating shaft 31 is rotatably connected to the ear shell 2, the user can apply a force to the ear shell 2 with the headband 1 and the rotating shaft 31 as a reference point so that the ear shell 2 can rotate away from the ear, and the user's ear can get rest and relaxation.

[0046] In some embodiments of the present invention, in one embodiment, the operating part 32 is sleeved outside the rotating shaft 31 along the axial direction of the rotating shaft 31, and a force is applied to the operating part 32 to make it move along the axial direction of the rotating shaft 31, and the limiting part is arranged on the operating part 32.

[0047] In some embodiments of the present invention, a limiting groove 311 and a first limiting protrusion 312 are provided on the rotating shaft 31, and a first circumferential locking portion 321 and an axial locking portion 322 are provided on the inner surface of the operating portion 32. The axial locking portion 322 is in limiting cooperation with the first limiting protrusion 312 to limit the axial movement of the ear shell 2 relative to the headband 1. In the locked state, the first circumferential locking portion 321 is in limiting cooperation with the limiting groove 311 to limit the circumferential movement of the ear shell 2 relative to the headband 1. In the unlocked state, the operating portion 32 separates the first circumferential locking portion 321 from the limiting groove 311, so that the ear shell 2 can rotate away from the ear. Through the limiting cooperation between the axial locking portion 322 and the first limiting protrusion 312 and the limiting cooperation between the first circumferential locking portion 321 and the limiting groove 311, the limiting of the inner surface of the ear shell 2 and the operating portion 32 is realized, so that the operating portion 32 cannot rotate relative to the rotating shaft 31, and the limiting between the outer surface of the operating portion 32 and the headband makes the operating portion 32 unable to rotate relative to the headband 1. Finally, the ear shell 2 is kept in a stable state where it cannot rotate relative to the headband 1, ensuring the reliability of the user during use.

[0048] In some embodiments of the present invention, the limiting cooperation between the operating portion 32 and the headband 1 can be that a protrusion is provided on the operating portion 32 and a groove is provided on the headband 1, or a groove is provided on the operating portion 32 and a protrusion is provided on the headband 1. In one embodiment, as Figures 6 to 8 and Figure 10 shown, a second limiting protrusion 11 is provided on the side of the headband 1 facing the operating portion 32, and a second circumferential locking portion 323 that is in limiting cooperation with the second limiting protrusion 11 is provided on the outer surface of the operating portion 32. Due to the limiting cooperation between the second limiting protrusion 11 of the headband 1 and the second circumferential locking portion 323 of the operating portion 32, and the operating portion 32 is movably connected to the ear shell 2, the user can apply a force to the ear shell 2 with the end point of the headband 1 as a reference point, so that the ear shell 2 can rotate away from the ear, and the user's ear can be rested and relaxed.

[0049] In some embodiments of the present invention, as Figures 2 to 9As shown, the head-mounted earphone further includes a first elastic member 33, and the first elastic member 33 is clamped between the operation portion 32 and the rotating shaft 31. When the user's ear needs to be relaxed, the user applies a force along the axial direction of the rotating shaft 31 to the operation portion 32, so that the operation portion 32 presses against the first elastic member 33, and further causes the first circumferential locking portion 321 to separate from the limiting groove 311. The rotating shaft 31 loses the circumferential restriction of the operation portion 32, and the ear shell 2 can rotate relative to the headband 1 to move away from the ear. After the first circumferential locking portion 321 separates from the limiting groove 311, the first elastic member 33 is in a deformed state, and the force generated by the deformation can cause the operation portion 32 to tend to move away from the first elastic member 33. The user applies a force to the ear shell 2 to rotate the ear shell 2 towards the ear. When the first circumferential locking portion 321 corresponds to the limiting groove 311, the force generated by the deformation of the first elastic member 33 drives the first circumferential locking portion 321 into the limiting groove 311 to form a circumferential limiting fit with the limiting groove 311 again, so that the ear shell 2 cannot rotate relative to the headband 1 towards the ear, that is, the ear shell 2 returns to the use state, and the ear shell 2 is kept in a stable state where it cannot rotate relative to the headband 1.

[0050] In some embodiments of the present invention, in order to reduce the overall size of the head-mounted earphone, a receiving groove 315 is provided on the end surface of the rotating shaft 31 that cooperates with the operation portion. A part of the first elastic member 33 is located in the receiving groove 315, and during the deformation process of the first elastic member 33, the receiving groove 315 can also play a guiding role to avoid the problem of the first elastic member 33 being deflected.

[0051] In some embodiments of the present invention, the first elastic member 33 can be a metal elastic sheet, a columnar spring or silica gel.

[0052] In some embodiments of the present invention, the head-mounted earphone further includes a second elastic member 4. The second elastic member 4 can be connected to the headband 1 through a plug-in structure or fixed to the headband 1 by screws 5. In one embodiment, such as Figures 2 to 7 and Figure 11As shown, one side of the headband 1 is provided with a socket groove 12 facing the auricle 2. One end of the two ends of the second elastic member 4 is connected to the headband 1 by a screw 5, and the other end is inserted into the socket groove 12. The middle area of the second elastic member 4 protrudes towards the rotating shaft 31 and abuts against the rotating shaft 31. And in the locked state, the second elastic member 4 has a preset deformation amount, and the acting force generated by the deformation can make the auricle 2 tend to move away from the ear. Due to the limiting cooperation among the operating part 32, the rotating shaft 31 and the headband 1, the auricle 2 cannot rotate relative to the headband 1 away from the ear. When the user applies a force to the operating part 32 towards the first elastic member 33 to press the first elastic member 33 so that the first circumferential locking part 321 is separated from the limiting groove 311, the rotating shaft 31 loses the circumferential restriction of the operating part 32. Under the action of the preset deformation amount of the second elastic member 4, the auricle 2 can automatically rotate relative to the headband 1 to move away from the ear. When the user applies a force to the auricle 2 to make the auricle 2 rotate towards the ear, the auricle 2 gradually presses against the second elastic member 4, making the second elastic member 4 return to the state with the preset deformation amount.

[0053] In some embodiments of the present invention, the second elastic member 4 can be a metal shrapnel, a torsion spring or silica gel.

[0054] In some embodiments of the present invention, the assembly between the operating part 32 and the rotating shaft 31 can be snap-fitted with the rotating shaft 31 through the deformation of the operating part 32 itself, or a structure for installing the operating part 32 can be provided on the rotating shaft 31. In one embodiment, as Figure 9 shown, in order to avoid excessive concentration of the deformation stress of the operating part 32, a first axial installation groove 313 and a second axial installation groove 314 are provided on the rotating shaft 31. The first circumferential locking part 321 slides along the first axial installation groove 313 and rotates after being separated from it, so that the first circumferential locking part 321 is in limiting cooperation with the limiting groove 311. The axial locking part 322 slides along the second axial installation groove and rotates after being separated from it, so that the axial locking part 322 is in limiting cooperation with the first limiting protrusion 312.

[0055] In some embodiments of the present invention, as Figures 2 to 5 and Figure 10As shown in the figure, two first buckles 13 rotatably connected to a rotating shaft 31 are spaced apart on one side of the headband 1 facing the ear cup 2. The opening of the first buckle 13 is smaller than the diameter of the rotating shaft 31. When assembling the ear cup 2 and the headband 1, when the rotating shaft 31 is pressed forcefully into the first buckle 13, the first buckle 13 deforms and the opening increases so that the rotating shaft 31 enters the inside of the first buckle 13 and is rotatably connected to the first buckle 13. On the side of the ear cup 2 facing the headband 1, a second buckle 211 fixedly connected to the rotating shaft 31 is provided. The fixed connection between the second buckle 211 and the rotating shaft 31 can be an integral structure or can be connected by screws, and the second buckle 211 is located between the two first buckles 13.

[0056] In some embodiments of the present invention, as Figure 1 shown, the headphone includes two ear cups 2. In one embodiment, both ear cups 2 are provided to be movably connected to the headband 1 through a connection structure 3. The connection structure 3 includes two groups of operating parts 32 and a limiting part. The two groups of operating parts 32 and the limiting part are respectively connected to both ends of the rotating shaft 31. When the user's ear needs to rest, the user needs to apply forces to the two operating parts 32 simultaneously, that is, apply opposite forces from both ends of the rotating shaft 31 to make the two operating parts 32 move relative to each other, which can prevent the headband 1 from displacing relative to the user's head and has a better use effect.

[0057] In some embodiments of the present invention, as Figure 1 shown, each ear cup 2 respectively includes a connection bracket 21 and an earphone cover 22 connected to the connection bracket 21. The rotating shaft 31 and the second buckle 211 are provided on the connection bracket 21. The connection bracket 21 is rotatably connected to the headband 1 through the rotating shaft 31. In the locked state, the connection bracket 21 is in limiting cooperation with the connection structure 3. In the unlocked state, the connection structure 3 is movably connected to the connection bracket 21 so that the connection bracket 21 can rotate away from the ear.

[0058] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
