A belt may not be used, and the versatility of the near-eye display device can be enhanced.

  Hereinafter, various embodiments of the near-eye display system according to the present invention will be described.

  First, a first embodiment of a near-eye display system according to the present invention will be described with reference to FIGS.

  As shown in FIGS. 1 and 2, the near-eye display system of the present embodiment includes a headphone 10 as a head-mounted device and a near-eye display device 20 that can be mounted on the headphone 10.

  The headphone 10 includes left and right speakers 11L and 11R, a headphone arm 12 that connects the left and right speakers 11L and 11R, and ear hooks 13L and 13R provided on the left and right speakers 11L and 11R. . The headphone 10 is a rear arm type headphone that turns the headphone arm 10 to the back of the user's head as shown in FIG.

  The near-eye display device 20 includes an image display unit 21 that displays an image in front of the user's eyes, a coupling unit 40 that is coupled to the headphone arm 12, and a support unit 30 that couples the image display unit 21 to the coupling unit 40. ing. The support portion 30 includes a bar-shaped display arm 31 having an elliptical cross section and an arm support portion 33 that supports the display arm 31. The coupling portion 40 is integrally formed with the arm support portion 33.

As shown in FIG. 3A, the coupling portion 40 is made of a material having elasticity, such as a resin, and has a C-shaped cross section. The interval d between the C-shaped open ends is slightly larger than the short diameter r ₂ of the headphone arm 12 whose section is elliptical, but is smaller than the long diameter r ₁ of the headphone arm 12. Therefore, with respect to the perspective direction A with respect to C-opening of the coupling portion 40, the closer the headphone arm 12 as minor r ₂ of the headphone arm 12 is perpendicular to the coupling portion 40, in the coupling portion 40, The headphone arm 12 can be easily inserted. Thereafter, when the headphone arm 12 is relatively rotated by 90 °, the headphone arm 12 is completely accommodated in the coupling portion 40 as shown in FIG. At this time, the coupling portion 40 is elastically deformed and slightly expands, and due to this elastic force, a sufficient frictional force acts between the coupling portion 40 and the display arm 12 to firmly hold the display arm 12. As a result, the near-eye display device 20 is coupled to the headphone arm 12.

  As described above, in the present embodiment, the near-eye display device 20 is attached to the headphone arm 12 simply by grasping the headphone arm 12, so that a dedicated head-mounted band is not used to attach the near-eye display. The versatility of the near-eye display device 20 can be enhanced. Further, in the present embodiment, since the headphone arm 12 is gripped by the elastic deformation of the coupling portion 40, even if the headphone arm 12 has a slightly different cross-sectional shape, it can be dealt with. Furthermore, since the headphone 10 does not have a special mounting structure for the near-eye display device, it is possible to improve the aesthetics when the headphone is used alone. Further, by coupling the near-eye display device 20 to either the left or right part of the headphone arm 12, the image display unit 21 can be positioned in front of the user's favorite eye. Since the coupling part 40 of the near-eye display device 20 can be slid, the image display part 21 can be positioned at an optimal position.

  As shown in FIG. 1, the arm support portion 33 that supports the display arm 31 is formed with an elliptical through hole 34 having the same cross-sectional shape as the display arm 31, and the display arm 31 is inserted into the through hole 34. ing. As shown in FIG. 5, the display arm 31 can slide with respect to the arm support portion 33, but the sliding amount is regulated by stoppers 32a and 32b provided on the display arm itself. As the stoppers 32a and 32b, the end portions (hereinafter referred to as rear end portions) opposite to the end portions (hereinafter referred to as front end portions) of the display arm 31 on the side where the image display portion is provided. And a retraction restricting stopper 32b provided between the front end portion and the rear end portion. As shown in FIG. 5, when the near-eye display device 20 is attached to the headphone arm 12 worn by the user, the display arm 31 is displayed on the display arm 31 more than the rearmost end He of the headphone arm 12 by the retraction restricting stopper 32b. The rear end portion Ae of the arm 31 is restricted so as not to go backward. The display arm 31 is curved corresponding to the face shape, and the image display unit 21 can be positioned at a distance of 20 mm or more between the user's eyes. The numerical value of 20 mm or more is a value that considers the use of the user by glasses.

  The display support unit 33 supports the display arm 31 and connects it to the coupling unit 40. In addition, when the coupling unit 40 is coupled to the headphone arm 12, the speaker 11L or 11R of the headphones 10 and the display arm 31 In order to avoid the mutual interference, the display arm 31 is also separated from the speaker 11L or 11R. Specifically, as shown in FIG. 2, the display support portion 33 has a relief portion 35 that extends in a direction away from the headphone arm 12 when the coupling portion 40 is coupled to the headphone arm 12. .

  As shown in FIG. 4, a signal line 28 and a power line 28 from the controller 29 extend to the image display unit 21 via a display arm 31 and an arm support unit 33. The image display unit 21 includes a display device 22, a display drive circuit 23 that drives the display device 22, an image processing circuit 24 that processes a signal from the controller 29 and controls the display drive circuit 23, and a vertical direction. It has a gravity sensor 26 that detects and notifies the image processing circuit 24 of the detection result, and a power supply circuit 25 that supplies power to them.

  The near-eye display device 20 of the present embodiment has symmetry in the vertical direction including the display screen of the image display unit 21 with respect to the vertical direction when the near-eye display device 20 is worn on the user's head. . For this reason, in FIG. 5, the near-eye display device 20 attached to the left side of the headphone arm 12 is attached to the right side of the headphone arm 12, so that the near-eye display device 20 can be used without a sense of incompatibility even when the near-eye display device 20 is turned upside down. it can. Further, even when the image display unit 21 is turned upside down due to a change in the left and right mounting position, this situation is detected by the gravity sensor 26 of the image display unit 21, and the display image is automatically turned upside down, and the upper side of the display image is displayed. Is displayed on the upper side, so that it is possible to eliminate the problem of the upside down image accompanying the change in the left and right mounting position of the near-eye display device 20.

  Next, the 1st and 2nd modification of the coupling | bond part 40 in this embodiment is demonstrated using FIG.6 and FIG.7, respectively.

  As shown in FIG. 6, the coupling portion 40a as a first modification includes a groove member 41 having a pair of side walls 42a and 42b facing each other, and one side wall (hereinafter referred to as a first side wall) of the groove member 41. A second grip portion 43 that grips the headphone arm 12 between the first grip portion 42a and a screw member 44 as a pressing member that pushes the second grip portion 43 toward the first grip portion 42a, have.

  The groove member 41 is formed integrally with the arm support portion 33. A side wall 42a on the arm support portion 33 side of the groove member 41 forms a first grip portion. A screw hole is formed in the other side wall 42b of the groove member 41, and a screw member 44 as a pressing member is screwed therein. The second grip 43 is attached to the tip of the screw member 44.

  When the coupling portion 40a is coupled to the headphone arm 12, a part of the headphone arm 12 is positioned between the first gripping portion 42a and the second gripping portion 43, and the screw member 44 is twisted. The distance between the first grip portion 42 a and the second grip portion 43 is narrowed, and the headphone arm 12 is gripped by the grip portions 42 a and 43.

  As shown in FIG. 7, the coupling portion 40 b as the second modification is obtained by replacing the screw member 44 as the pressing member in the first modification with a spring coil 44 b that is an elastic member.

  When the coupling portion 40b is coupled to the headphone arm 12, the space between the first gripping portion 42a and the second gripping portion 43 is widened and the spring coil 44b is contracted. When a part is positioned, the second grip 43 is pushed toward the first grip 42 b by the elastic force of the spring coil 44 b, and the headphone arm 12 is gripped between the grips 42 b and 43.

  As described above, also in the first and second modified examples, the near-eye display device 20 is attached to the headphone arm 12 simply by gripping the headphone arm 12, so that the near-eye display device 20 is the same as in the first embodiment. The versatility of can be improved. In these modified examples, since the headphone arm 12 is gripped by the deformation of the coupling portions 40a and 40b due to the movement of the second gripping portion 43, the headphone arm 12 may have a slightly different cross-sectional shape. can do.

  Next, first and second modifications of the headphone 10 according to the present embodiment will be described with reference to FIGS. 8 and 9, respectively.

  As shown in FIG. 8, the headphone 10a of the first modification is formed by forming a plurality of convex portions 14 having a large outer diameter at regular intervals in the vicinity of the left and right ends of the headphone arm 12a. The interval between the convex portions 14 and 14 is substantially the same as the width of the coupling portion 40 of the near-eye display device 20 in the above embodiment, and the projection portion 14 and 14 are coupled to each other to which the coupling portion 40 is coupled. A coupling portion 15 is formed.

  As described above, the position of the near-eye display device 20 with respect to the headphone arm 12a can be changed by forming a plurality of convex portions 14, 14,... And a plurality of coupled portions 15, 15,. Of course, the user can immediately attach the near-eye display device 20 to the user's favorite position by remembering the position of the coupled portion 15.

  In this modification, the portion between the coupled portions 15, 15 is projected from the coupled portion 15 over the entire circumference to form the convex portion 14, but this convex portion 14 is Since it is for regulating the slide of the near-eye display device 20, it is not necessary to project the part between the coupled parts 15 and 15 over the entire circumference, and project only a part of it. It is good also as a convex part.

  As shown in FIG. 9, the headphone 10b of the second modified example has a left and right end portions 15b of the headphone arm 12b that are larger in outer diameter than other portions of the headphone arm 12b and have increased rigidity. is there.

  In this way, by increasing the outer diameter of the coupled portion 15b of the headphone arm 12b, which is the coupling portion of the near-eye display device 20, and increasing the rigidity, the near-eye display device 20 displays an image on the headphone arm 12b. The relative position of the part 21 can be stabilized.

  In the second modified example, a plurality of engaged portions and a plurality of convex portions similar to those in the first modified example may be formed in a portion having a large outer diameter of the headphone arm 12b.

  Moreover, although each modification of these headphones 10a and 10b is a headphone which was aimed at to some extent with respect to the near eye display apparatus 20 of previous embodiment, it is different from the near eye display apparatus 20 of previous embodiment. This is a suitable headphone and does not reduce the versatility of the near-eye display device itself.

  Next, a second embodiment of the near-eye display system according to the present invention will be described with reference to FIGS.

  As shown in FIGS. 10 and 12, the near-eye display system of the present embodiment also includes a headphone 10 and a near-eye display device 20 a that can be attached to the headphone 10. The headphone 10 is the same as the headphone 10 of the first embodiment. The near-eye display device 20a is basically the same as that of the first embodiment, but the support portion 30a that supports the image display portion 21 is different from that of the first embodiment.

  The support portion 30a of the present embodiment has a display arm 31a to which the image display portion 21 is attached at one end portion, and a storage portion 33a for storing the display arm 31a.

  As shown in FIG. 12, the storage portion 33a includes a storage case 36 that stores the display arm 31a, and a plurality of bearings 37 that slidably support the display arm 31a. In the storage case 36, an opening 34a through which the display arm 31a enters is formed on one end side, and an escape portion 35 is formed on the other end side. Similar to the first embodiment, the display arm 31a is formed with a stopper stopper 32a at the rear end thereof, but is not formed with a backward restricting stopper. This is because the inner wall of the storage case 36 serves as a stopper that restricts the retreat of the display arm 31a.

  In the present embodiment, similar to the first embodiment, as shown in FIG. 13, the near-eye display device 20a can be attached to either the right side or the left side of the headphone arm 12. Further, the coupling unit 40 of the present embodiment may employ any one of the modifications of the coupling unit in the first embodiment. Also, the headphone arm 12 of the present embodiment may employ any one of the modifications of the headphone arm of the first embodiment.

  Next, a third embodiment of the near-eye display system according to the present invention will be described with reference to FIGS.

  As shown in FIG. 14, the near-eye display system of the present embodiment also includes a headphone 10c and a near-eye display device 20c that can be attached to the headphone 10c. The headphone 10c of this embodiment is basically the same as the headphone 10 of the first embodiment, but in the first embodiment, the ear hooks 13L and 13R provided on the left and right speakers 11L and 11R are the same. Instead, it differs from the first embodiment in that ear hooks 13c, 13c are formed at both ends of the headphone arm 12c. The near-eye display device 20c is basically the same as that of the first embodiment, but the support portion 30c that supports the image display portion 21 is different from that of the first embodiment.

  The support portion 30c of the present embodiment includes a display arm 31c to which the image display portion 21 is attached at one end, and a storage portion 33c that stores the display arm 31c.

  As in the second embodiment, the storage portion 33c includes a storage case 36c that stores the display arm 31c and a plurality of bearings 37 that slidably support the display arm 31c, as shown in FIG. Yes. In the storage case 36c, an opening 34c through which the display arm 31c enters is formed on one end side, and an escape portion 35c is formed on the other end side. A displacement mechanism 50 is provided in the escape portion 35c of the storage case 36c. The displacement mechanism 50 changes the relative position and orientation of the image display unit 21 with respect to the coupling unit 40, and is formed on the ball 51 provided on the coupling unit 40 and the other end side of the storage case 36c. And a ball receiving portion 52. A certain amount of frictional force acts between the ball 51 and the ball receiving portion 52. Unless a certain amount of rotational force acts on the ball receiving portion 52, Thus, the ball receiving portion 52 cannot be rotated relatively.

  Thus, by configuring the displacement mechanism 50 with the ball 51 and the ball receiving portion 52, as shown in FIGS. 15 and 16, around each of three independent axes in the three-dimensional space, The support part 31c and the image display part 21 supported by the support part 31c can be displaced. Specifically, the axis in the direction in which the portion of the headphone arm 12c coupled to the coupling unit 50 extends is the X axis, the direction perpendicular to the X axis and the ball 51 is formed with respect to the coupling unit 50 If the axis extending in the direction Y is the Y axis, and the axis perpendicular to the X axis and the Y axis is the Z axis, the support portion 31c and the image display portion 21 are rotated about the respective axes X, Y, and Z around the ball 51. be able to.

  In addition, the displacement mechanism 50 of this embodiment may be provided between the support part 30c and the image display part 21, or may be provided in the support part 30c. However, since the displacement mechanism 50 itself is heavy, a displacement mechanism may be provided between the coupling portion 40 and the support portion 30c as in the present embodiment in order to reduce the moment with respect to the coupling portion 40 as much as possible. preferable. In this embodiment, the ball 50 is formed on the coupling portion 40 side, but it goes without saying that the ball 50 may be formed on the storage case 36c side and the ball receiving portion 52 may be formed on the coupling portion 40 side.

  In addition, regarding the coupling portion 40 of the present embodiment, any one of the modifications of the coupling portion in the first embodiment may be employed. Furthermore, regarding the headphone arm 12c of this embodiment, any one of the modifications of the headphone arm in the first embodiment may be adopted.

  Next, a first modification and a second modification of the displacement mechanism in the third embodiment will be described with reference to FIGS.

  As shown in FIG. 17, the displacement mechanism of the first modified example uses a flexible wire 53 instead of the ball 51 in the third embodiment. The flexible wire 53 is formed by weaving a thin wire to form a wire having a constant thickness, filling a resin around the gap between the thin wires and a certain thickness, and deforming when a certain load is applied. If this happens, the deformed state is maintained unless a constant load is applied again.

  One end of the flexible wire 53 is fixed to a wire receiving portion 55 formed in the storage case 36 c, and the other end is fixed to a wire receiving portion 54 extending from the coupling portion 40. Thus, even if the flexible wire 53 is used in place of the ball 51 in the third embodiment, the flexible wire 53 is deformed in various directions, so that the independent in the three-dimensional space is obtained as in the third embodiment. The supporting portion 30c and the image display portion 21 supported by the supporting portion 30c can be displaced around each of the three axes.

  The displacement mechanism of the second modified example is a further modified example of the first modified example, as shown in FIGS. 18 and 19, in which only one end of the flexible wire 53 is fixed.

  One end portion of the flexible wire 53 is fixed to a wire receiving portion 55 formed in the storage case 36c, as in the first modification. The other end of the flexible wire 53 is supported so as to be slidable in a direction in which the flexible wire 53 extends with respect to a wire receiving portion 54 b extending from the coupling portion 40. Further, in the storage case 36c, the portion around the wire receiving portion 54b extending from the coupling portion 40 is the direction in which the portion of the headphone arm 12c coupled to the coupling portion 40 extends, that is, the direction parallel to the X axis. A notch 39 is formed in the notch.

  As described above, when the displacement mechanism 50b is configured, as in the first modification, the flexible wire 53 is deformed in various directions, so that each of the three independent axes X, Y, Z in the three-dimensional space. Around, the support part 31c and the image display part 21 supported by the support part 31c can be displaced. Further, by sliding the flexible wire 53 fixed to the storage case 36c with respect to the wire receiving portion 54b extending from the coupling portion 40, as shown in FIG. 19, the support portion 31c and the support portion 31c are supported. The image display unit 21 supported by the part 31c can be moved in the direction in which the flexible wire 53 extends.

  Here, as shown in FIG. 19, when the flexible wire 53 extends in the X-axis direction, the sliding of the flexible wire 53 with respect to the wire receiving portion 54 b extending from the coupling portion 40 causes the support portion 31 c and the image. The processing unit 21 moves in parallel with the X axis. However, when the flexible wire 53 is deformed and bent, for example, in the Y axis direction or the Z axis direction, naturally, the flexible wire 53 is bent. The support part 31c and the image processing part 21 move in the direction.

  In this modification, one end portion of the flexible wire 53 is fixed to the wire receiving portion 55 formed in the storage case 36c, and the other end portion is slidable by the wire receiving portion 54b extending from the coupling portion 40. In contrast, one end of the flexible wire 53 is slidably supported by a wire receiving portion extending from the coupling portion 40, and the other end is supported by a wire receiving portion formed in the storage case 36c. It may be fixed.

  Further, it goes without saying that each of the displacement mechanisms 50, 50a, 50b described above can be applied to the one having no storage portion, that is, the first embodiment. For example, when the displacement mechanism 50 of the third embodiment is applied to the first embodiment, a ball receiving portion is formed on the arm support portion 35 and a ball is formed on the coupling portion 40. In addition, when the displacement mechanism 50 a of the second modification is applied to the first embodiment, a wire receiving portion is formed in each of the arm support portion 35 and the coupling portion 40. In this case, in order to prevent the flexible wire from coming off from the wire receiving portion extending from the coupling portion 40, it is preferable to provide a stopper at the end of the flexible wire.

  The above embodiments are all directed to rear arm type headphones, but the present invention is not limited to this, and is applied to a head arm type that turns an arm around the user's head. Also good. Moreover, although the above embodiment is directed to headphones including a speaker, if the head mounting device includes an arm that is mounted on the head by sandwiching the user's head from the left and right, the speaker is used. Even if it is not provided, the present invention may be applied.
