When a user plays a video game or enjoys video content, the user sits in a chair, looks at a display placed on a desk in front of the chair, and listens to the video displayed on the display. Sometimes I hear the sound of flowing water. Some of the sounds that accompany the images are compatible with surround sound. In order for a user to hear sound compatible with surround sound while sitting in front of a desk (facing the desk), the sound must not only come from in front of the user sitting in the chair (on the desk side). Instead, it is necessary to radiate sound toward the user from the sides and rear.

Patent Document 1 discloses a desk in which a speaker unit is disposed at the end of the top plate facing the user's seating position. Further, Patent Document 2 discloses a configuration in which speakers are provided on both sides of a chair using arms. For example, by combining the configurations of Patent Documents 1 and 2 and using speakers installed on both sides of the chair as rear speakers that radiate sound toward the user from the sides or rear, the user can enjoy surround sound. You can hear the corresponding sound.

(First embodiment)
A first embodiment of the present disclosure will be described below with reference to FIGS. 1 to 4.
As shown in FIGS. 1 and 2, the speaker-equipped desk 1 of the first embodiment includes a desk 2, two arms 3, and two rear speakers 4 (speakers). Further, the speaker-equipped desk 1 includes a front speaker 5 and a display 6.

The desk 2 includes a top plate 11 and legs 12. The top plate portion 11 is formed into a flat plate shape with the thickness direction facing in the vertical direction, and has a top plate surface 11a facing upward. The legs 12 are attached to the lower side of the top plate part 11 and support the top plate part 11 from below. The top plate part 11 is positioned above an installation surface (not shown) on which the desk 2 is installed with a space provided therebetween by legs 12 .

In the drawings, the vertical direction (thickness direction of the top plate portion 11) is shown as the Z-axis direction. The Z-axis positive direction indicates the upper side or the upper side, and the Z-axis negative direction indicates the lower side or the lower side. Further, in the drawings, the direction perpendicular to the Z-axis direction (the direction along the top plate surface 11a) is shown as the X-axis direction and the Y-axis direction.
In the speaker-equipped desk 1 of this embodiment, it is assumed that the user is located on the Y-axis positive direction side of the desk 2. Therefore, in the following description, the X-axis direction is taken as the width direction of the desk 2, and the Y-axis direction is taken as the front-rear direction of the desk 2, with the position of the user facing the desk 2 as a reference. Furthermore, the positive direction of the Y-axis is defined as the front or front side, and the negative direction of the Y-axis is defined as the rear or rear side.

Two arms 3 are attached to the desk 2. The two arms 3 are movable between a storage position P1 and a use position P2, respectively. The storage position P1 is a position where the entire arm 3 is placed below the top plate portion. The use position P2 is a position where the arm 3 protrudes from the edge of the top plate surface 11a when viewed from a direction (Z-axis direction) perpendicular to the top plate surface 11a of the top plate portion 11. In this embodiment, when the arm 3 is placed at the use position P2, the arm 3 protrudes from the edge of the top plate surface 11a in a direction along the top plate surface 11a.
The two arms 3 disposed at the use position P2 are spaced apart from each other and extend parallel to each other from the edge of the top plate surface 11a. Specifically, the two arms 3 disposed at the use position P2 are located at both ends of the top plate portion 11 in the width direction. Further, these two arms 3 each extend forward (in the front direction) from the front edge of the top plate surface 11a. The two arms 3 arranged at the use position P2 are arranged so as to form a space sandwiched between these two arms 3.

In this embodiment, each arm 3 is attached to the desk 2 so as to be linearly movable between a storage position P1 and a use position P2. Specifically, each arm 3 is constituted by one rod-shaped member extending linearly. Each arm 3 is movable in the front-back direction (Y-axis direction) with respect to the desk 2 between the storage position P1 and the use position P2 by means of a rail 9 attached to the lower surface 11b side of the top plate part 11. There is. Therefore, in this embodiment, the arm 3 disposed at the storage position P1 is located below the top plate portion 11 so that its longitudinal direction follows the front-rear direction of the desk 2.
The arm 3 and rail 9 of this embodiment described above are each formed into a cylindrical shape having a cavity inside.

The two rear speakers 4 are provided at the tips of the two arms 3, respectively. The distal end portion of the arm 3 is a portion located at the distal end in the protruding direction of the arm 3 when the arm 3 is placed at the use position P2. Each rear speaker 4 is located below the top plate portion 11 together with the arm 3, with the arm 3 disposed at the storage position P1.
The two rear speakers 4 are preferably arranged so that the sound of the rear speakers 4 is radiated toward the space between the two arms 3 with the two arms 3 disposed at the use position P2. In other words, the two rear speakers 4 may be arranged so that sound is radiated toward the user located between the two arms 3 arranged at the use position P2. In FIG. 1, a radiation surface 4a from which sound is mainly radiated among the surfaces of the rear speaker 4 is directed toward the space between the two arms 3 disposed at the use position P2.

As shown in FIG. 3, the rear speaker 4 is rotatably attached to the tip of the arm 3. In this embodiment, the rear speaker 4 is arranged around the arm 3 around a first axis R1 extending in the front-rear direction (Y-axis direction), around a second axis R2 extending in the up-down direction (Z-axis direction), and in the width direction. It is rotatable around a third axis R3 extending in the X-axis direction. By rotating the rear speaker 4 about the first axis R1 with respect to the arm 3, the direction of sound emitted from the rear speaker 4 can be changed in the vertical direction. Further, by rotating the rear speaker 4 about the second axis R2 with respect to the arm 3, the direction of sound emitted from the rear speaker 4 can be changed in the front-rear direction. The rear speaker 4 may be attached to the tip of the arm 3 by, for example, a ball joint.
For example, the rear speaker 4 may be rotatable with respect to the arm 3 about any one or two of the first axis R1, the second axis R2, and the third axis R3. For example, a structure such as a ball joint that rotatably attaches the rear speaker to the arm 3 may be configured so that the orientation of the rear speaker 4 with respect to the arm 3 is maintained unless an external force is applied to the rear speaker 4.

As shown in FIG. 4, electric wiring 7 extending from the rear speaker 4 is inserted into the inside of each arm 3 formed in a cylindrical shape. The electrical wiring 7 is a wiring for transmitting an electrical signal for generating sound at the rear speaker 4 from an amplifier (not shown) or the like to the rear speaker 4. In this embodiment, the electric wiring 7 is also inserted through a rail 9 formed in a cylindrical shape.

As shown in FIGS. 1 and 2, the front speaker 5 is provided on the top plate surface 11a. A radiation surface 5a of the front speaker 5, from which sound is mainly radiated, is directed forward. In this embodiment, the front speakers 5 are arranged at both ends and at the center of the top plate surface 11a in the width direction. The front speaker 5 located at the center functions as a center speaker. The front speaker 5 may be detachably attached to the top plate 11 or may be fixed to the top plate 11.

The display 6, like the front speaker 5, is provided on the top plate surface 11a. A display surface 6a of the display 6 that displays images and videos is directed forward. The display 6 may be detachably attached to the top plate 11 or may be fixed to the top plate 11.

In the speaker-equipped desk 1 configured as described above, the user faces the front speaker 5 in the front-rear direction while being located between the two arms 3 arranged at the use position P2. In this state, the front speaker 5 is located in front of the user, and the two rear speakers 4 are located on the sides or behind the user. Thereby, the user can hear sound corresponding to the surround sound by the sound radiated from the two rear speakers 4 and the front speaker 5.
In addition, in the speaker-equipped desk 1, the rear speaker 4 and the front speaker 5 can output sound that matches the image displayed on the display surface 6a of the display 6. Therefore, with the speaker-equipped desk 1, it is possible to enjoy, for example, video games and various video contents.

As explained above, in the desk with speakers 1 of this embodiment, the rear speakers 4 are provided at the tips of the two arms 3 that extend parallel to each other from the edge of the top plate portion 11 along the top plate surface 11a. There is. As a result, the user of the speaker-equipped desk 1 faces the desk 2 so as to be positioned between the two arms 3, so that the two rear speakers 4 can be positioned on the left and right sides of the user. That is, sound can be radiated from these two rear speakers 4 toward both left and right sides of the user or toward the rear side of the user.
In the speaker-equipped desk 1, two arms 3, each having a rear speaker 4 at its tip, are movable between a storage position P1 and a use position P2. Thereby, the rear speaker 4 can be installed and cleaned up easily.

Furthermore, in the speaker-equipped desk 1 of this embodiment, the arm 3 is linearly movable in the longitudinal direction of the arm 3 with respect to the desk 2 between the storage position P1 and the use position P2. As a result, the locus that the arm 3 moves between the storage position P1 and the use position P2 is limited to the longitudinal direction of the arm 3, so the space required for moving the arm 3 in and out of the desk 2 can be minimized. can.

In addition, in the speaker-equipped desk 1 of this embodiment, the rear speaker 4 is rotatably attached to the tip of the arm 3. Therefore, the direction of sound emitted from the rear speaker 4 can be adjusted. As a result, the direction of the sound emitted from the rear speaker 4 can be adjusted appropriately according to the position of the user (especially the position of the user's head and ears) between the two arms 3 placed at the usage position P2. Can be adjusted.

Furthermore, in the speaker-equipped desk 1 of this embodiment, the electrical wiring 7 extending from the rear speaker 4 is inserted into the arm 3. Therefore, when the arm 3 is moved in and out of the desk 2, it is possible to suppress or prevent the electrical wiring 7 from becoming entangled with or caught on the arm 3 or the user's limbs. Therefore, the arm 3 and the rear speaker 4 attached to the arm 3 can be easily taken in and out of the desk 2.
Furthermore, since the electrical wiring 7 is not exposed to the outside, the external design of the speaker-equipped desk 1 can be improved.

In the first embodiment, for example, as shown in FIGS. 5 to 7, the arms 3C and 3D that are attached to the desk 2 so as to be linearly movable are extendable and retractable in the longitudinal direction (Y-axis direction) of the arms 3C and 3D. There may be. In such a configuration, the arms 3C and 3D are arranged at the use position P2 by extending, and are arranged at the storage position P1 by contracting. Since the arms 3C and 3D placed in the storage position P1 are retracted, the arms 3C and 3D can be stored compactly below the top plate portion 11.

The arm 3C illustrated in FIGS. 5 and 6 has a plurality of arm elements 31. The plurality of arm elements 31 are arranged in the longitudinal direction (Y-axis direction) of the arm 3C in a state where the arm 3C is placed at the use position P2. Adjacent arm elements 31 are relatively movable along the longitudinal direction of arm 3C. In the arm 3C, the arm 3C can be expanded and contracted by relatively moving the adjacent arm elements 31.

The arm 3D illustrated in FIG. 7 is configured by a telescopic link mechanism 34 like a magic hand, which is configured by connecting a plurality of cross links 33, which are formed by connecting two links 32 rotatably to each other in the middle. There is. In the arm 3D, the arm 3D can be expanded and contracted by relatively rotating the connected links 32.

(Second embodiment)
Next, a second embodiment of the present disclosure will be described with reference to FIG. 8. In the following description, components that are common to those already described will be given the same reference numerals and redundant description will be omitted.

As shown in FIG. 8, in the speaker-equipped desk 1E of the second embodiment, two arms 3E are located at the storage position P1 on the lower side of the top plate part 11 and at the top of the top plate part 11, as in the first embodiment. It is movable between a use position P2 protruding from the edge of the plate surface 11a in a direction along the top plate surface 11a. In addition, the two arms 3E are located at both ends of the top plate portion 11 in the width direction when placed in the use position P2, and extend forward from the front edge of the top plate surface 11a. Moreover, each arm 3E is constituted by one rod-shaped member extending linearly.

In the second embodiment, each arm 3E is rotatably attached to the desk 2 around the base end of the arm 3E, which is located on the desk 2 side when placed at the use position P2. Specifically, the rotation shaft 35 of each arm 3E located at the base end of each arm 3E extends in the vertical direction. Therefore, the arm 3E rotates relative to the desk 2 within a plane along the top plate surface 11a.

The arm 3E rotates from a use position P2, where the tip thereof is located at the end of the top plate 11 in the width direction, to a storage position P1 so as to move inward of the top plate 11 in the width direction. Thereby, the locus of the arm 3E that rotates between the use position P2 and the storage position P1 can be prevented from protruding to the outside of the top plate portion 11 in the width direction. Note that the arm 3E may be rotated to the storage position P1, for example, so that the tip of the arm 3E moves from the use position P2 to the outside of the top plate portion 11 in the width direction.
The arm 3E disposed at the storage position P1 may extend in the width direction of the top plate portion 11 as illustrated in FIG. 8, but the present disclosure is not limited to such an example. The arm 3E disposed at the storage position P1 may extend, for example, in the front-back direction.

According to the speaker-equipped desk 1E of the second embodiment, the same effects as the first embodiment are achieved.
Further, in the speaker-equipped desk 1E of the second embodiment, the arm 3E is rotatably attached to the desk 2 between the storage position P1 and the use position P2. As a result, compared to the speaker-equipped desk 1 of the first embodiment in which the arm 3 moves linearly with respect to the desk 2, it can be manufactured at low cost with fewer parts. To explain this point, in order to move the arm 3 in a straight line, a plurality of bearings, rollers, attachments, etc. are required. On the other hand, in order to rotationally move the arm 3E, only the rotation hinge (rotation shaft 35) needs to be provided. Thereby, the speaker-equipped desk 1E can be manufactured at low cost with a small number of parts.
Further, since the arm 3E rotates between the storage position P1 and the use position P2, the arm 3E can be easily moved with a smaller force than when moving in a straight line.

Furthermore, in the speaker-equipped desk 1E of the second embodiment, the arm 3E disposed at the storage position P1 extends in the width direction of the top plate portion 11. Therefore, a space can be secured below the desk 2 (top plate portion 11) to accommodate the feet of the user of the speaker-equipped desk 1E. To explain this point, in the speaker-equipped desk 1 of the first embodiment, the arm 3 disposed at the storage position P1 (lower side of the top plate 11) is moved forward and backward at both ends of the top plate 11 in the width direction. extending in the direction. Therefore, the space for accommodating the user's feet on the lower side of the top plate 11 is narrow in the width direction of the top plate 11. In contrast, in the speaker-equipped desk 1E of the second embodiment, the arm 3 disposed at the storage position P1 (below the top plate 11) extends in the width direction of the top plate 11. Therefore, the space for accommodating the user's feet on the lower side of the top plate portion 11 can be prevented from becoming narrow in the width direction of the top plate portion 11. Therefore, a space can be secured below the desk 2 (top plate portion 11) to accommodate the feet of the user of the speaker-equipped desk 1E.

In the second embodiment, for example, as shown in FIG. 9, the arm 3F may include a plurality of arm elements 36 rotatably connected to each other. The plurality of arm elements 36 are arranged in the longitudinal direction (Y-axis direction) of the arm 3F in a state where the arm 3F is placed at the use position P2. Adjacent arm elements 36 are rotatably connected to each other. The rotation shaft 37 connecting adjacent arm elements 36 may extend in the same direction as the rotation shaft 35 located at the base end of the arm 3F, as illustrated in FIG. It may extend in different directions. In the desk with speaker 1E illustrated in FIG. 9, the number of arm elements 36 is two, but the number may be three or more.
Since the adjacent arm elements 36 are rotatably connected, the arm 3F can be folded when the arm 3F is placed in the storage position P1. Therefore, the arm 3F can be stored compactly below the top plate portion 11.

In the second embodiment, the direction in which the rotation shafts 35 of the arms 3E, 3F extend may be arbitrary. For example, as shown in FIG. 10, the rotation shaft 35 of the arm 3E may extend in the width direction (X-axis direction). In this case, the arm 3E disposed at the storage position P1 may extend, for example, in a direction along the top plate surface 11a, but may also extend in the vertical direction, as shown in FIG. 10, for example. That is, the arm 3E may extend downward from the top plate portion 11 while being placed in the storage position P1.

(Third embodiment)
Next, a third embodiment of the present disclosure will be described with reference to FIG. 11. In the following description, components that are common to those already described will be given the same reference numerals and redundant description will be omitted.

As shown in FIG. 11, in the speaker-equipped desk of the third embodiment, a rear speaker 4 is provided at the tip of each arm 3H, similar to the first embodiment.
However, in the third embodiment, the rear speaker 4 is formed into a cylindrical shape having a cavity inside. The rear speaker 4 is arranged inside the arm 3H. An opening 38 is formed at the tip of the arm 3H to allow sound emitted from the rear speaker 4 to propagate to the outside of the arm 3H. A protective sheet 39 such as a mesh sheet or nonwoven fabric is provided in the opening 38 to prevent dust from entering the inside of the arm 3H. Note that the protective sheet 39 does not need to be provided in the opening 38 of the arm 3H.
In FIG. 11, the opening 38 is oriented toward the inside of the desk 2 in the width direction, similar to the radiation surface 4a of the rear speaker 4 of the first embodiment (see FIG. 1).

According to the desk with a speaker of the third embodiment, the same effects as the first embodiment are achieved.
Furthermore, in the desk with speakers of the third embodiment, since the rear speakers 4 are hidden inside the arm 3H, the rear speakers 4 appear to be integrated into the arm 3H, so that the external design can be improved. .

In the third embodiment, the rear speaker 4 may be rotatably attached to the tip of the arm 3H, for example, similarly to the first embodiment. In this case, the opening 38 of the arm 3H may be directed not only to the inside of the desk 2 in the width direction, but also to the upper side or lower side of the arm 3H, or to the front side of the arm 3H.

(Fourth embodiment)
Next, a fourth embodiment of the present disclosure will be described with reference to FIG. 12. In the following description, components that are common to those already described will be given the same reference numerals and redundant description will be omitted.

As shown in FIG. 12, in the speaker-equipped desk of the fourth embodiment, a rear speaker 4I is provided at the tip of each arm 3I, similar to the first embodiment.
However, in the fourth embodiment, the rear speaker 4I includes a box body 41 and a sound emitting section 42. The sound emitting part 42 is attached to the box body 41 and emits sound to the outside and inside of the box body 41. Such a structure of the rear speaker 4I may also be applied to the rear speaker 4 of the first to third embodiments.
The arm 3I is formed into a cylindrical shape with a cavity inside. The cavity of the arm 3I communicates with the internal space of the box 41 of the rear speaker 4I. In FIG. 12, the arm 3I is formed integrally with the box 41 of the rear speaker 4I.

According to the speaker-equipped desk of the fourth embodiment, the same effects as the first embodiment are achieved.
Furthermore, in the desk with speakers of the fourth embodiment, the cavity of the arm 3I communicates with the internal space of the box 41 of the rear speaker 4I. Therefore, the arm 3I can be used as a port (enclosure) for the rear speaker 4I. Thereby, the volume of the box 41 of the rear speaker 4I can be substantially increased. Therefore, it becomes possible to radiate sound with acoustic characteristics with enhanced bass range from the rear speaker 4I.

In the fourth embodiment, for example, the arm 3I and the box body 41 of the rear speaker 4I are formed separately, and the arm 3I and the box body 41 are arranged so that the cavity of the arm 3I and the internal space of the box body 41 communicate with each other. The body 41 may be connected. In this case, the rear speaker 4I (particularly the box body 41) may be rotatably attached to the arm 3I, for example, similarly to the first embodiment.

(Fifth embodiment)
Next, a fifth embodiment of the present disclosure will be described with reference to FIG. 13. In the following description, components that are common to those already described will be given the same reference numerals and redundant description will be omitted.

In the desk with speaker 1G of the fifth embodiment, the arm 3G (arm with speaker, speaker) is attachable to and detachable from the top plate portion (desk) 11. In the example of FIG. 13, only one arm 3G is shown, but the number of arms 3G is not limited to one. The number of arms 3G may be two or more.

The arm 3G includes a plurality of arm elements rotatably connected to each other, that is, an arm element 36a and an arm element 36b. The arm element 36a and the arm element 36b are connected to each other by a rotating shaft 60. The arm element 36a and the arm element 36b are mutually rotatable about the rotation axis 60. The arm 3G further includes a rear speaker (speaker) 4 fixed to the arm element 36b.

The arm 3G further includes a U-shaped attachment portion 50 for removably attaching the arm 3G to the top plate portion 11. The mounting portion 50 and the arm element 36a are connected to each other by a rotating shaft 61. The rotation axis 61 is orthogonal to the rotation axis 60. The arm 3G is attached to the top plate part 11 by pushing the attachment part 50 into the top plate part 11. More specifically, the top plate part 11 is inserted into the internal space formed by the U-shaped attachment part 50. The arm 3G is removed from the top plate part 11 by pulling out the attachment part 50 with respect to the top plate part 11.

When the arm 3G ( arm elements 36a, 36b) is located at the use position P2, the arm element 36a and the arm element 36b are mutually rotatable around a rotation axis 60 extending in the vertical direction (Z-axis direction). . In addition, when the arm 3G ( arm elements 36a and 36b) is located at the use position P2, the arm element 36a rotates around the rotation axis 61 extending in the width direction (X-axis direction) of the desk 2 with respect to the mounting portion 50. It is said to be rotatable.

When the attachment part 50 is attached to the top plate part 11 and the arm 3G ( arm elements 36a, 36b) is placed in the storage position P1, the entire arm elements 36a, 36b are located below the top plate part 11. When the attachment part 50 is attached to the top plate part 11 and the arm 3G ( arm elements 36a, 36b) is arranged at the use position P2, the arm elements 36a, 36b are arranged in a direction perpendicular to the top plate surface 11a of the top plate part 11. It protrudes from the edge of the top plate surface 11a when viewed from the Z-axis direction.

According to the desk with a speaker of the fifth embodiment, the same effects as the first embodiment are achieved. Further, since the arm 3G can be attached to and detached from the desk, it can be applied to a general desk that is not provided with rear speakers in advance.

In the fifth embodiment of the present disclosure, the configuration of the attachment portion is not limited to the example in FIG. 13. For example, as shown in FIG. 14, the arm 3G may include a clip-shaped attachment portion 51 instead of the attachment portion 50. The attachment portion 51 includes a pair of sandwich portions 51A, 51B and a spring 51C. The sandwich parts 51A and 51B are rotatably connected to each other by a rotating shaft 63. Furthermore, the sandwich parts 51A and 51B are connected to each other by a spring 51C. The attachment part 51 is attached to the top plate part 11 by inserting the top plate part 11 into the internal space formed by the sandwich parts 51A and 51B.
