Head-mounted electronic device

This application is a continuation application of PCT Patent Application No. PCT/CN2015/087564, entitled “HEAD-MOUNTED DISPLAY DEVICE” filed on Aug. 19, 2015, which is incorporated by reference in its entirety.

The present disclosure relates to head-mounted electronic devices, and more particularly relates to a head-mounted electronic device having a headphone and a display portion capable of rotating relative to each other.

As a near-eye display device, the head-mounted electronic device generates images and projects the images to eyes of a user, which enables the user to watch amplified virtual images, thus a greater display effect can be obtained accordingly. Currently, as for most of head-mounted electronic devices, audio is transmitted to the user by an earphone coupled thereto. However, sound effect obtained by the earphone is usually common. Thus, to overcome this disadvantage, some product is integrated with a headphone having a better sound effect. The angle between the headphone and a display portion is a predetermined angle, for example, 90 degrees, which facilitates the user to easily wear the headphone and also allows the user to watch images projected by the display portion. Although this design provides a better sound and video effect, the overall volume is too big to carry around.

Embodiments of the present application provide a head-mounted electronic device having a headphone and a display portion which are capable of rotating relative to each other, and it is convenient to carry around the head-mounted electronic device.

The head-mounted electronic device includes a headphone and a display portion. The headphone includes a C-shaped elastic belt and has two connection ends, and two sound generators connected to the connection ends respectively. The display portion includes a main body configured for generating and projecting images, and two connection members which are connected to opposite ends of the main body respectively and are rotatably connected to the sound generators respectively. A part of each connection member arranged between the corresponding sound generator and the main body defines a notch.

In the present application, when the display portion is rotated relative to the headphone, possible distortion of the display portion is limited to the connection member where the notch is defined, which may protect the main body and the sound generator from deformation, thus facilitating the display portion to rotate relative to the headphone.

Various embodiments of the present application will be specifically illustrated in combination with the detailed embodiments and the following accompanying drawings. It should be understood that each component in the accompanying drawings is not representative of the actual size and scale, which is a schematic just for illustration, and is not to be construed as a limitation of the present application.

It should be understood that the specific embodiments described herein are merely used to illustrate the present application, and are not a limitation of the present application. Moreover, the display does not represent the actual scale of each element of the present application, and are just schematic. It must be pointed out that the “connection” between two elements mentioned in the present application does not necessarily refer to direct connection between two elements, and can be indirect connection between the two elements which is realized by a third element.

FIG. 1 is a perspective view of a head-mounted electronic device 10 in a first embodiment of the present application. The head-mounted electronic device 10 may be a head-mounted video player, a head-mounted game device, a head-mounted navigator, or the like. The head-mounted electronic device 10 includes a headphone 20 and a display portion 40 . The display portion 40 can be rotatably connected to the headphone 20 . By doing so, referring to FIG. 1 , in a used state, the display portion 40 can be rotated to angle with the headphone 20 in 90 degrees. At this point, after a user wears the headphone 20 , the display portion 40 is located at the front of user's eyes and projects images to the user's eyes. Referring to FIG. 5 , when in an idle state, the display portion 40 can be rotated to overlap with the headphone 20 to facilitate storing the headphone 20 .

Referring to FIGS. 1-2 , the headphone 20 includes two sound generators 22 , an elastic belt 24 , and two movable members 26 for movably connecting the two sound generators 22 to the elastic belt 24 . The elastic belt 24 is substantially C-shaped, and has two connection ends 25 at the C-shaped open. The elasticity of the elastic belt 24 allows the two connection ends 25 to move close to each other or away from each other. In the embodiment, each connection end 25 includes a sleeve portion 25 a and a first sliding member 25 b slideably received in the sleeve portion 25 a . A first protruding post 25 c protrudes from a side of the first sliding member 25 b away from the sleeve portion 25 a . A portion of the first sliding member 25 b is capable of sliding out of the sleeve portion 25 a . The first protruding post 25 c defines a first axis 25 d . The configuration of the first sliding member 25 b allows the user to adjust the distance between the elastic belt 24 and the sound generators 22 . It should be understood that, the first sliding member 25 b is optional when the elastic belt 24 can be elongated or there is no need to adjust the distance between the elastic belt 24 and the sound generators 22 .

Each movable member 26 is rotatably connected to the corresponding connection end 25 about the first axis 25 d , which enables the movable member 26 to rotatable around the first axis 25 d relative to the connection end 25 . In the embodiment, the movable member 26 is substantially arc-shaped, and includes an arc-shaped base body 26 a , a first through hole 26 b recessing from an end of the base body 26 a adjacent to the connection end 25 , and a second protruding post 26 c extending from the other end of the base body 26 a in a direction toward the sound generator 22 . The first protruding post 25 c is inserted into and latched onto the first through hole 26 b , which enables the first protruding post 25 c to be able to rotate in the first through hole 26 b.

Each sound generator 22 is rotatably connected to the corresponding movable member 26 about a second axis 26 d , which enables the sound generator 22 to be able to rotate around the second axis 26 d on the movable member 26 . In the embodiment, each sound generator 22 includes an inner wall 22 a from which the voice emanating, an outer wall 22 b opposite to the inner wall 22 a , and a sidewall 22 c extending from a rim of the outer wall 22 b to the inner wall 22 a . The sidewall 22 c in the embodiment is a cylindrical wall. The outer wall 22 b cooperates with the sidewall 22 c to form a chamber (not shown). The loudspeaker (not shown) of the sound generator 22 is received in the chamber with a side from which the voice generate facing the inner wall 22 a . The sidewall 22 c defines a second through hole 22 d . The second protruding post 26 c is inserted into the second through hole 22 d , and is further latched onto the chamber, which enables the sound speaker 22 to rotate around the second protruding post 26 c , namely, the second protruding post 26 c defines the second axis 26 d . The second axis 26 d angles with the first axis 25 d in an angle α. Therefore, the sound generator 22 and the movable member 26 are rotatable around the first axis 25 d , and the sound generator 22 is also rotatable around the second axis 26 d , thereby enabling the sound generator 22 rotating in multiple dimensions. It is noted that, configurations of the mentioned protruding posts 25 c , 26 c and through hole 26 b , 22 d can be reversed, for example, the movable member includes the first protruding post 25 c , while the first through hole 26 b is defined on the connection end 25 .

The display portion 40 includes a main body 42 and two connection members 44 . The main body 42 is used for generating and projecting images. In detail, the main body 42 includes image generating devices and optical modules (not shown). Images generated by the image generating device pass through the optical module and is projected toward a scheduled direction. An adjustment structure (not shown) is arranged on the main body 42 . The adjustment structure is used for adjusting a distance between the image generating device and the optical module, so as to fit in with different eyesight of users. The adjustment structure is also used to adjust the distance between groups of the image generating device and the optical module, to fit in with different pupillometer.

The two connection members 44 are connected to opposite ends of the main body 42 , each connection member 44 is rotatably connected to a corresponding sound generator 22 around a third axis 22 e . The third axis 22 e extends from the outer wall 22 b toward the inner wall 22 a . Therefore, the display portion 40 is capable of rotating to a position separating from the headphone 20 , shown in FIG. 1 , and a position where the display portion 40 overlaps with the headphone 20 , shown in FIG. 5 . In the embodiment, each connection member 44 includes a rotating member 44 a and a connection sheet 44 b . The connection sheet 44 b defines a notch 44 c . For example, the notch 44 c is defined in the middle of the connection sheet 44 b . The configuration of the connection sheet 44 c lessens the width of the portion of the connection sheet 44 b where the notch 44 c is located, thereby enabling the connection sheet 44 b to be easily deformed during the sound generators 22 being unfolded when the user wears or takes off the head-mounted electronic device, to further lessen possibility of the main body 42 being deformed, and thus to protect the main body 42 . The rotating member 44 a is connected to an end of the connection sheet 44 b adjacent to the sound generator 22 . The rotating member 44 a in the embodiment is substantially annular, and includes a cylindrical wall. The rotating member 44 a engages the side wall 22 c of the sound generator 22 by a latching member 44 d , thereby enabling the rotating member 44 a being rotatable around a center axis of the sidewall 22 c . Therefore, the sidewall 22 c of the sound generator 22 defines the mentioned third axis 22 e . The third axis 22 e is substantially perpendicular to the first axis 25 d and/or the second axis 26 d.

Preferably, each connection member 44 further includes a rubber 44 e . The notch 44 c is filled with rubber 44 e . The configuration of the rubber 44 e is beneficial for the deformation of the connection sheet 44 b , and also protects the connection sheet 44 b from breaking apart at the same time.

When the head-mounted electronic device 10 is assembled and is in a use state, referring to FIG. 1 , the display portion 40 can be rotated to a position angling with the headphone 20 in 90 degrees, without external force. It should be noted that the recited 90 degrees is merely for illustration, various habits of users may result in different angles, for example, 70 degrees, 80 degrees, or 100 degrees. At this time, referring to FIG. 3 , ends of the sound generators 22 away from the elastic belt 24 slants toward each other, thus, a second angle β is formed between different third axis 22 e of the sound generator 22 . The configuration of the second angle β makes for the sound generator 22 to be further fit users' ears.

Referring to FIG. 1 and FIG. 3 , when the display portion 40 is rotated to overlap with the headphone 20 , the display portion 40 is rotated in an upward direction shown in FIG. 3 . Because the third axis 22 e is slant relative to the horizontal direction shown in FIG. 3 , and the main body 42 cannot be elongated, thus, when the display portion 40 is rotated upwardly, the right sound generator 22 in FIGS. 1 and 3 is driven to rotate around the second axis 26 d anticlockwise (see the arrow signed on the second axis 26 d in FIG. 1 ), namely, a side of the right sound generator 22 adjacent to the first through hole 26 b rotates in a direction adjacent to the other sound generator 22 , and the other sound generator 22 rotates in a reverse direction. At the same time, the upward rotation of the display portion 40 also drives the right sound generator 22 and the right movable member 26 in FIGS. 1 and 3 to rotate around the first axis 25 d in an arrow direction marked thereon, namely, a side of the right sound generator 22 adjacent to the second protruding post 26 c rotates in a direction away from to the other sound generator 22 .

Based on the above description, in the embodiment, because of the configuration of the second angle β, the sound generator 22 is well fit users' ears, which results in better audio effect. However, at this point, the third axis 22 e is not horizontally disposed, namely, the two third axises 22 e are not aligned with each other but angle with each other, thus the process of the display portion 40 rotating relative to the headphone 20 becomes more complex. In this situation, if the elastic belt 24 is fixed to the sound generator 22 directly, that is, the movable member 26 is omitted, the elastic belt 24 and the connection member 44 will deform during the display portion 40 rotating relative to the sound generator 22 . However, in the embodiment, after the movable member 26 is arranged to the headphone 20 , the sound generator 22 is rotatable around the above two-dimensional to allow the sound generator 22 is driven by the display portion 40 to rotate around the first axis 25 d and the second axis 26 d , thereby protecting the elastic belt 24 and the connection member 44 from distortion, and further enabling the display portion 40 can rotate to overlap with the headphone 20 .

In above embodiment, the base body 26 a of the movable member 26 extends for a quarter of a circle, that is, the first angle α is substantially 90 degrees. However, it should be understood that the sound generator 22 can also rotates in two-dimensional to achieve the above purpose. Therefore, the first angle α is not limited to 90 degrees. Preferably, the first angle α is greater than 30 degrees but is less than 150 degrees, or is greater than 210 degrees but is less than 330 degrees. At this time, the length of the main body 26 a is changed accordingly.

In the above embodiment, the second angle β is substantially 150 degrees when no external force is applied to the head-mounted electronic device 10 . However, it should be understood that for different persons, the second angle β may change, on condition that the head-mounted electronic device 10 can be well fit in with user's ears. Preferably, the second angle β is greater than 100 degrees but is less than 170 degrees.

Preferably, the movable member 44 is movably connected to the main body 42 or the sound generator 22 , thus the movable member 44 is movable to a first position adjacent to the main body 42 or the sound generator 22 and a second position away from the main body 42 or the sound generator 22 . As a result, the distance between the main body 42 and users' eyes can be adjusted. In detail, referring to FIG. 4 , take the movable member 44 being movably connected to the main body 42 as an example, the display portion 40 further includes two support members 46 extending outwardly from opposite ends of the main body 42 , and the connection member 44 slidably engages with the support members 46 , thereby enabling the main body 42 to be closed to or away from the sound generator 22 . Means of the connection member 44 being movably connected to the sound generator 22 is similar to that of the connection member 44 being movable connected to the main body 42 , which will not be repeated herein.

It is understood that, when the movable member 26 in the above embodiment is omitted and the connection member 44 retains the configuration of notch 44 c , referring to FIG. 6 , that is, the head-mounted electronic device 12 includes a headphone 20 ′ and the display portion 40 . The headphone 20 ′ includes a substantially C-shaped elastic belt 24 with two connection ends, and two sound generators 22 connected to the connection ends respectively. The display portion 40 includes a main body 42 for generating and projecting out images and two connection members 44 . The connection members 44 are coupled to opposite ends of the main body 42 and are rotatably connected to the sound generators 22 respectively. A portion of each connection member 44 between the corresponding sound generator 22 and the main body 42 defines a notch 44 c . Because the connection member 44 deforms easily at the notch 44 c , possible distortion of the display portion 40 is limited to the connection member 44 where the notch 44 c is defined, which may protect the main body 42 and the sound generator 22 from deformation, thus facilitating the display portion 40 to easily rotate relative to the headphone 20 .
