Description

Headset with display unit

[0001] The disclosure below relates to a headset device having a display unit.

[0002]

[0003] Historically, devices that provide users with images have taken a variety of forms, including those that transmit sound. Previous devices have focused on the design and form of video equipment capable of implementing visual images in emerging VR, AR, and XR environments. These devices often began with a display in the form of glasses or goggles, then incorporated speakers into the device. Despite this, for various reasons, a unified form factor has yet to be established.

[0004] The two representative approaches to solving this problem are the glass method and the goggle method.

[0005] Research on smart glasses has been active from the past to the present, with numerous inventions incorporating speakers into smart glass devices equipped with displays. However, these approaches have revealed various limitations, such as durability and the weight of the device on the bridge of the nose. To this day, global giants like Google are conducting commercial research to create more user-friendly devices using this smart glass method.

[0006] Meanwhile, headgear and goggle-style devices that cover the field of vision stemming from VR are also being actively developed. However, these devices also present challenges, such as weight, fatigue from prolonged use in visually isolated environments, and the tight pressure of the band-like structure worn around the face. Nevertheless, research continues worldwide to establish a universal form factor using this method, including from Meta, which concluded that this approach is desirable for implementing increasingly advanced visuals, and Sony, which manufactures gaming devices.

[0007] In this rapidly developing competition among form factors, the market's desire for new types of devices that can deliver vivid sound while incorporating rapidly developing video technology is growing louder.

[0008]

[0009] An object of one embodiment is to provide a new concept headset device capable of simultaneously providing a user with images reproduced on a display while providing high quality sound.

[0010] The purpose of one embodiment is to propose a headset device that can be worn by a user for a long period of time and can effectively transmit sound and images without causing discomfort during use.

[0011] In addition, the purpose of one embodiment is to propose a new structural form factor that can be commercialized and can be used for a long time without any problems, overcoming the problems of conventional smart glass or goggle-type devices that have not been commercialized.

[0012] A headset including a rotatable display unit according to one embodiment of the present invention comprises: a headband and ear caps connected to both ends of the headband through connecting portions; a display unit mounted on a display band connected from the connecting portions; and the display band may be rotatable from a first position where the display unit overlaps the headband to a second position where the display unit is positioned in front of the user's eyes, with the connecting portion as an axis.

[0013] In one embodiment, the connecting portion may include a click module, and the rotation may be performed semi-automatically by pressing a button of the click module located at the connecting portion.

[0014] According to one embodiment, the connecting portion further includes a mainspring, and the semi-automatically performed rotation may utilize a rotational force generated by the release of the mainspring.

[0015] In one embodiment, the manner in which the display band returns from the second position to the first position may be manually driven.

[0016] In one embodiment, the connecting portion may include at least one: an axis extending from the center of the button in a third direction perpendicular to the button; a pinion gear mounted on one end of the extended axis; a mainspring mounted on the extended axis adjacent to the pinion gear; and a spring compressibly provided in the third direction along the axis between the button and the pinion gear.

[0017] In one embodiment, the connecting portion may further include a reduction portion that reduces the speed when the display band approaches the second position after the rotation is initiated, and the reduction portion may be meshed with the pinion gear.

[0018] In one embodiment, the rotation may be performed after the display band is extended away from the user's head.

[0019] According to one embodiment, the display band may be a structure extending from a shaft mounted on the connecting portion, and the extension may be achieved by the shaft vertically rising from the connecting portion when the button is pressed.

[0020] According to one embodiment, the connecting portion may have a spring provided at the other end of the shaft where the display band is located, and when the button is pressed, the shaft may rise vertically by the elastic force of the spring.

[0021] According to one embodiment, the connecting portion further includes a vertical gear fixed to the shaft; a pinion gear having one side meshed with the vertical gear and rotating; and a mainspring having the same rotational axis as the pinion gear; and when the shaft rises vertically, the mainspring is released, thereby increasing the rotational force of the pinion gear.

[0022] According to one embodiment, the connecting portion further includes a reduction portion engaged with the other side of the pinion gear; and the reduction portion may control a descending speed during the rotational movement of the display band.

[0023]

[0024] According to another embodiment of the present invention, a headset including a rotatable display unit includes: a headband; ear caps connected to both ends of the headband; a rotation module located on a surface of the ear caps; and a display unit mounted on a display band connected to the rotation module; wherein the display band is rotatable from a first position where the display unit overlaps the headband to a second position where the display unit is located in front of the user's eyes when the rotation module is rotated.

[0025] In one embodiment, the rotation module may include a gear structure for rotational motion and a stopper for limiting the rotational radius.

[0026] According to one embodiment, the rotation module may include a length adjustment portion of the display band having a bar structure extending in one direction.

[0027] According to one embodiment, when the display band rotates, the length adjustment part of the display band of the bar structure also rotates, and the rotation radius of the display band may be limited when the bar structure is caught by the stopper.

[0028] In one embodiment, a touch pad may be positioned on the outer surface of the rotating module.

[0029]

[0030] According to another embodiment of the present invention, a method of using a headset including a rotatable display unit is provided, wherein the headset includes a headband and ear caps connected to both ends of the headband through connecting portions; and a display unit mounted on a display band connected to the connecting portion; and when a user wishes to watch an image through the display unit, when a button located at the connecting portion is pressed, the display band may rotate from a first position where the display unit overlaps the headband to a second position where the display unit is located in front of the user's eyes, with the connecting portion as an axis.

[0031] According to one embodiment, a headset including a rotatable display unit is worn by overlapping a headband with ear cups and a display band on the upper part of the head, and when the display unit is used, the display band with the display unit is rotated to position the display in front of the user's eyes. Through this, the user can enjoy images through the display unit and sounds through the ear cups.

[0032] In one embodiment, the headset can be driven in such a way that when a button is pressed by introducing a click module, the display portion that was overlapped with the headband is semi-automatically positioned in front of the user's eyes.

[0033] The embodiments proposed in the present invention are more user-friendly than other form factors introduced to date for enjoying images and sounds simultaneously, and can solve the problem of the display lens part being touched by hand, causing the field of vision to become contaminated, or the ear cap or headband part coming off from the original wearing position when the user lowers the display part fixed to the head with his hand.

[0034] By introducing the concept proposed in the present invention, it is possible to solve problems of various form factors that have previously limited commercialization at once using a simple and uncomplicated method.

Unless otherwise stated, the descriptions given in one embodiment may also apply to other embodiments, and detailed descriptions will be omitted to the extent of overlap.

[0058]

[0059] FIG. 1 is a drawing illustrating a first use state of a headset including a rotatable display unit according to one embodiment. FIG. 2 is a drawing illustrating a second use state of a headset including a rotatable display unit according to one embodiment.

[0060] Hereinafter, the structure of a headset including a rotatable display unit proposed in the present invention, the driving method of each component, and the method of use thereof will be described in detail with reference to FIGS. 1 and 2.

[0061] A headset including a rotatable display unit according to one embodiment of the present invention comprises: a headband and ear caps connected to both ends of the headband through connecting portions; a display unit mounted on a display band connected from the connecting portions; and the display band may be rotatable from a first position where the display unit overlaps the headband to a second position where the display unit is positioned in front of the user's eyes, with the connecting portion as an axis.

[0062] Referring to FIG. 1, the headset has a headband (130) including ear caps (140) at both ends, and a display band (110) having a display unit (120) mounted thereon may be positioned on the outer side of the headband (the side located farther from the user's head) so as to overlap the headband in a first use state. In this way, when the display unit is not in use, the display unit may overlap the headband.

[0063] For the convenience of the user, the above-mentioned ear cap may not be fixed to the headband, but may include a rotating part at the part connected to the headband, so that the angle at which the ear cap is connected to the headband may change. The above-mentioned ear cap may include a touch sensor or button on the outer surface of the ear cap or the inner side of the outer cover, as needed, to enhance the user interface convenience. The touch sensor or button may transmit a signal according to the user's intention when the headset operates in conjunction with an external electronic device.

[0064] The earcups may include a charging port or battery compartment. The display band of the headset rotates mechanically, but power may be required to operate the display of the display unit. In this case, a battery may be installed within the earcups, or an external power supply terminal may be provided on the earcups to supply electricity.

[0065] The above headband may include a length adjustment part that can adjust the length according to the user's head size.

[0066] Referring to FIG. 2, in the second use state, the display band rotates toward the user's front and is positioned in front of the user's eyes. In the second use state, the user can view images through the display unit.

[0067] In FIGS. 1 and 2, the display band is shown as being positioned on the outside of the head band, but it is also within the technical concept of the present invention that the display band is positioned on the inside of the head band.

[0068] At this time, it may be more preferable that the display band be positioned on the outside of the head band. This is because, when the head band is positioned on the inside, it can be positioned stably despite the rotation of the display band by being in close contact with the user's head. In addition, when the display band is positioned on the inside of the head band, the user's hair may contaminate the inner lens of the display band or the user's hair may be continuously rubbed when the display band rotates. To solve this problem, it may be more preferable that the display band be positioned on the outside of the head band.

[0069] The display portion of the above display band may be formed with a structure that is somewhat spaced apart from the outer side of the headband. This allows for protection of the lens of the display portion and smooth rotational movement, and also ensures that the lens of the display portion is appropriately positioned in front of the user's eyes when rotating.

[0070]

[0071] FIG. 3 is a drawing showing one form of a connection part (200) of a headset including a rotatable display part according to one embodiment.

[0072] Fig. 4 is a drawing showing the internal structure of a connecting part according to the form illustrated in Fig. 3 by projection, and Fig. 5 is a drawing showing the connection relationship of each part from the side to show the joint structure between parts of the connecting part according to the form illustrated in Fig. 3.

[0073] Figures 3 to 5 are examples of a design in which the display band can rotate due to the elasticity of the spring when the button of the click module located at the connection part is pressed.

[0074] In one embodiment, the connecting portion may include a click module, and the rotation may be performed semi-automatically by pressing a button of the click module located at the connecting portion.

[0075] In one embodiment, the connecting portion may include at least one: an axis extending from the center of the button in a third direction perpendicular to the button; a pinion gear mounted on one end of the extended axis; a mainspring mounted on the extended axis adjacent to the pinion gear; and a spring compressibly provided in the third direction along the axis between the button and the pinion gear.

[0076] The click module may include a button that can be retracted inwardly and is located at the center of the connecting portion. The button of the click module may be vertically arranged at one end of a shaft on which a first spring (222) and a second spring (224) are mounted, as illustrated in FIG. 5. A pinion gear (230) that assists rotational motion may be mounted at the other end of the shaft. In one example, the button of the click module may be arranged parallel to the pinion gear.

[0077] The mainspring may be positioned adjacent to the pinion gear and on the same axis. The pinion gear may rotate together by utilizing the force of the mainspring being released, thereby causing the display band to rotate.

[0078] The semi-automatic rotational motion described above may be a rotational motion utilizing the physical structure of a mechanical device without the introduction of electronic means. The headset connection part proposed in the above embodiment is designed to enable a semi-automatic rotational motion by designing a simple mechanical device without the introduction of complex means such as using a separate internal or external power source. Here, semi-automatic means a motion in which the display band rotates on its own when the user presses the button on the click module. In this case, the semi-automatic rotation may utilize the rotational force generated by the release of the mainspring as the downward force of the display band. Of course, if the user lowers the display band while standing, gravity may additionally affect the rotation.

[0079]

[0080] While the rotation from the first position to the second position is implemented semi-automatically, the manner in which the display band returns from the second position to the first position may be manually driven.

[0081] According to one embodiment, the connecting portion further includes a reduction portion (270) that reduces the speed when the display band approaches the second position after the rotation is initiated, and the reduction portion may be meshed with the pinion gear.

[0082] The display unit, which has weight during the rotational motion, may be driven through the above-mentioned reduction unit so as not to shock the user. The above-mentioned reduction unit may also be provided using only the simple physical structure of a gear, without the introduction of any electromagnetic means.

[0083]

[0084] FIGS. 6 to 10 disclose a headset according to another embodiment that rotates in another manner. The structures disclosed in FIGS. 6 to 10 do not operate in a manner in which the display portion immediately rotates when the button on the click module is simply pressed. In the headset of the structure disclosed in FIGS. 6 to 10, when the button on the click module is pressed, the display band first extends away from the user's head (in an example, a vertically upward direction), and then, after being sufficiently extended, rotates toward the user's eyes by releasing the mainspring.

[0085] In one embodiment, even in this manner of rotating after extension, the headset can be presented as a headset that does not include any electromagnetic means and is driven only by the introduction of physical, mechanical components.

[0086] FIG. 6 is a drawing showing another form of a connection part (200) of a headset including a rotatable display part according to one embodiment.

[0087] FIGS. 7 and 8 disclose the connection relationship between the components of the headset connection unit that can be driven to rotate after the above-described extension. FIG. 7 is a drawing showing the connection relationship of each component as viewed from one side to illustrate the joint structure between the components of the connection unit according to another embodiment illustrated in FIG. 6, and FIG. 8 is a drawing showing the connection relationship of each component as viewed from the other side to illustrate the joint structure between the components of the connection unit according to another embodiment illustrated in FIG. 6.

[0088] FIGS. 9 and 10 disclose the positions and movements of each component of the headset connection unit that can be driven to rotate after the extension and each stage of the display band. FIG. 9 is a drawing showing a form in which each component operates sequentially when the button of the click module is pressed in the connection unit according to another form shown in FIG. 6, and FIG. 10 is a drawing showing a form in which the display band is driven in a manner of rising and then falling when the button of the click module is pressed in the connection unit according to another form shown in FIG. 6.

[0089]

[0090] In one embodiment, the rotation may be performed after the display band is extended away from the user's head.

[0091] To enable this extension, the display band may introduce a shaft (240) into the connection portion.

[0092] According to one embodiment, the display band may be structured to extend from a shaft (240) mounted on the connecting portion, and the extension may be achieved by the shaft vertically rising from the connecting portion (220) when the button is pressed.

[0093] Additionally, according to one embodiment, the connecting portion may have a spring (third spring, 226) provided at the other end of the shaft where the display band is located, and when the button is pressed, the shaft may rise vertically by the elastic force of the spring.

[0094] In order for the shaft to vertically rise, in one example, the display band and the shaft may be coupled, and the shaft may be raised when the button of the click module is pressed, by introducing a rack gear, a vertical gear, and a pinion gear meshing with the vertical gear. In addition, in one embodiment, a mainspring having the same rotational axis as the pinion gear may be further included. By introducing the mainspring, when the shaft vertically rises, the rotational force of the pinion gear may be increased as the mainspring is released.

[0095] As shown in the left picture of Fig. 9, when the button of the click module is pressed, the shaft fixed to the shaft groove is removed, and the display band rises vertically by the force of the third spring. As shown in the middle picture of Fig. 9, it can be confirmed that the vertical gear fixed to the shaft is rising by the elasticity of the spring. At this time, the pinion gear connected to the vertical gear rotates, and the rotational force of the pinion gear increases by the release of the mainspring having the same axis as the pinion gear.

[0096] According to one embodiment, the connecting portion further includes a reduction portion (270) that is engaged with the other side of the pinion gear (230), and the reduction portion may control the descending speed during the rotational movement of the display band. This is also to prevent the user's headband wearing state from being affected despite the rotation due to the weight of the display portion, as in the previous embodiment.

[0097] Looking at the right picture of Fig. 9, one can see that after the vertical gear has fully ascended, the display band and shaft rotate 90 degrees due to the release of the mainspring. During this rotational movement, the reduction gear in contact with the other side of the pinion gear serves to reduce the descending speed of the display band.

[0098]

[0099] Hereinafter, the structure of a headset including a rotatable display unit according to another embodiment will be described in detail with reference to FIGS. 11 to 14.

[0100] FIG. 11 is a drawing showing the structure of a rotation module of a headset including a rotatable display unit according to another embodiment, and FIG. 12 is a drawing showing the internal structure of a rotation module of a headset including a rotatable display unit according to another embodiment and an assembly step thereof.

[0101] A headset according to another embodiment of the present invention may include a rotating module formed and attached to an outer surface of an ear cap of the headset.

[0102] According to another embodiment of the present invention, a headset including a rotatable display unit includes: a headband; ear caps connected to both ends of the headband; a rotation module located on a surface of the ear caps; and a display unit mounted on a display band connected to the rotation module; wherein the display band is rotatable from a first position where the display unit overlaps the headband to a second position where the display unit is located in front of the user's eyes when the rotation module is rotated.

[0103]

[0104] In one embodiment, the rotation module may include a gear structure for rotational motion and a stopper for limiting the rotational radius.

[0105] According to one embodiment, the rotation module may include a length adjustment portion of the display band having a bar structure extending in one direction.

[0106] According to one embodiment, when the display band rotates, the length adjustment part of the display band of the bar structure also rotates, and the rotation radius of the display band may be limited when the bar structure is caught by the stopper.

[0107] Figure 13 illustrates a situation in which the length-adjusting portion of the display band of a headset including a rotatable display portion according to the embodiment described above is caught by a stopper, thereby limiting the rotation radius. In this case, the stopper may be formed as a protruding convex structure, and may be physically caught when the bar structure rotates, thereby limiting the rotation radius.

[0108] The above-described rotation module may be formed by assembling a rotation module housing, a hinge mounted inside the housing, an external gear for rotation, a housing cover including an internal gear for rotation and a protruding stopper, and a rotation driving operation unit thereon. In one example, the rotation module housing may be designed to have a structure that rotates together when the rotation module rotates, and in another example, the rotation module housing may be designed to have a structure that is fixed to the display band and only the cover and the rotation driving operation unit rotate.

[0109] FIG. 14 is a drawing showing a second use state of a headset including a rotatable display unit according to another embodiment.

[0110]

[0111] According to another embodiment of the present invention, a method of using a headset including a rotatable display unit is provided, wherein the headset includes a headband and ear caps connected to both ends of the headband through connecting portions; and a display unit mounted on a display band connected to the connecting portion; and when a user wishes to watch an image through the display unit, when a button of a click module located at the connecting portion is pressed, the display band may rotate from a first position where the display unit overlaps the headband to a second position where the display unit is located in front of the user's eyes, with the connecting portion as an axis.

[0112] A headset including the above-described rotatable display unit may be a headset according to one embodiment of the present invention.

[0113] According to the method of using the above headset, when rotating the headset from the second position to the first position, the user may move the display band to the first position by hand.

[0114] The rotational motion of the above headset does not utilize any electromagnetic means and is operated solely by the actuation of physical or mechanical components.

[0115]

[0116] Although the embodiments described above have been described with limited drawings, those skilled in the art will appreciate that various technical modifications and variations can be applied based on the above. For example, appropriate results can still be achieved even if the described techniques are performed in a different order than described, and / or components of the described systems, structures, devices, circuits, etc. are combined or combined in a different manner than described, or are replaced or substituted with other components or equivalents.

[0117] Therefore, other implementations, other embodiments, and equivalents to the claims also fall within the scope of the claims described below.
