  The base 100 is formed of a metal such as aluminum, iron, magnesium, or titanium, a resin such as polypropylene or polyethylene, a fiber reinforced resin, or wood. The base 100 may be formed of a composite material in which different materials are combined.

  Since one or a plurality of microphones are arranged on the base 100, the base 100 is formed to have a strength capable of fixing a microphone holder that holds the one or more microphones.

  The base 100 is formed in a circular flat plate shape. The surface of the base 100 is a single color such as black or a predetermined pattern such as a wood grain pattern. For example, when used at a relatively high position from the floor, if the surface of the base 100 is matte black, the base 100 is less noticeable. Further, when used at a low position on the stage, if the surface of the base 100 is made of a wood grain pattern, the stage 100 is usually formed of a wooden plate, so that the base 100 is less noticeable.

  The circumference of the base 100 is equally divided into n (integers), and a fixed hole 101 having a circular shape is provided along the circumference of the base 100 on a line connecting the position where the circumference is divided and the center. For example, six fixing holes 101 are provided along the circumference of the base 100 on a line connecting the center and the position where the circumference of the base 100 is divided into six equal parts.

  The fixing hole 101 is a hole through which a male screw that penetrates from the top surface to the bottom surface of the base 100 and is screwed into a microphone holder that holds the microphone is passed. The fixing hole 101 is formed in a shape that allows a male screw of W3 / 8 inch to pass through. The fixing hole 101 may be formed in a shape that allows male screws to pass through other standards such as PF1 / 2, NS5 / 8 inch, or U5 / 16 inch of JIS / BTS (broadcast technical standard) standard. .

  The through hole 102 is a long hole provided along the circumference of the base 100 between the two fixing holes 101. The through hole 102 is a long hole that bends along the circumference of the base 100 with a curvature according to the curvature of the circumference of the base 100. When n fixing holes 101 are provided, the through holes 102 are provided between sets of two adjacent fixing holes 101 among the n fixing holes 101. When n fixing holes 101 are provided, n through holes 102 are provided.

  For example, when six fixing holes 101 are provided, the through holes 102 are respectively provided between the two fixing holes 101. That is, in this case, six through holes 102 are provided.

  The through hole 102 is a hole through which a male screw that penetrates from the top surface to the bottom surface of the base 100 and is screwed into a microphone holder that holds the microphone is passed. The through hole 102 is formed in a shape that allows a male screw of W3 / 8 inch to pass through. The fixing hole 101 may be formed in a shape that allows male screws to pass through other standards such as PF1 / 2, NS5 / 8 inch, or U5 / 16 inch of JIS / BTS (broadcast technical standard) standard. .

  The circumference of the base 100 is equally divided into n (integers), and a cable through hole 103 for passing a microphone cable is provided on the inner circumference side of the fixing hole 101 on a line connecting the position where the circumference is divided and the center. ing. The cable through hole 103 penetrates from the upper surface to the bottom surface of the base 100 and has a larger diameter than the fixing hole 101. For example, the diameter of the cable through hole 103 is set to ½ or more of the length of the microphone.

  By providing the cable through hole 103, the base 100 can be thinned, and the weight of the base 100 can be further reduced.

  For example, when six fixing holes 101 are provided, one cable through hole 103 is provided on the inner peripheral side of each fixing hole 101. In this case, six cable through holes 103 are provided.

  A support 104 is provided at the center of the bottom surface side of the base 100. The support 104 has a female screw that is screwed into a microphone stand or a tripod. For example, the female screw provided on the support 104 is a female screw that is screwed into a W3 / 8 inch male screw.

  For example, when six fixing holes 101 are provided, three cable through holes 201 are provided.

  Providing the cable through hole 201 can increase the degree of freedom of the posture of the microphone disposed on the base 100.

  FIG. 8 is a diagram showing a base according to still another embodiment of the present invention. As in the case shown in FIG. 6, the same reference numerals are given to the portions, and description thereof is omitted.

  The cable through hole 301 is formed in a keyhole shape, and is provided on a line that divides the circumference of the base 100 equally into n (integer) and connects the circumference and the center. The cable through hole 301 penetrates from the upper surface to the bottom surface of the base 100.

  That is, the peripheral side of the base 100 of the cable through hole 301 is a width through which a male screw that is screwed into a microphone holder that holds a microphone is passed, and a length from the circumference to the center on a line connecting the position where the circumference is divided and the center. The shape of the hole. For example, the peripheral side of the base 100 of the cable through hole 301 is formed in a shape that allows a male thread of W3 / 8 inch to pass through. The center side of the base 100 of the cable through hole 301 has a larger diameter than the peripheral side of the base 100 of the cable through hole 301, and is a portion for passing the microphone cable.

  That is, the cable passage hole 301 is a hole through which a male screw that is screwed into the microphone holder is passed, and is a long hole that goes from the circumference toward the center, and has a shape that is connected to the hole through which the cable of the microphone is passed.

  Providing the cable through hole 301 can increase the degree of freedom of the posture of the microphone disposed on the base 100.

  FIG. 9 is a diagram showing a base 100 on which a plurality of microphones are arranged. A male screw that is screwed into a microphone holder 402 that holds the microphone 401 is passed through the fixing hole 101 or the through hole 102 of the base 100, and this male screw and the microphone holder 402 (female screw) are screwed together, A microphone holder 402 is fixed to the base 100.

  A male screw that is screwed into a microphone holder 402 that holds the microphone 401 is passed through the fixing hole 101 of the base 100, and the male screw and the microphone holder 402 are screwed together to fix the microphone holder 402 to the base 100. In this case, since the microphone holder 402 is fixed to the base 100 so that it cannot be moved in the circumferential direction of the base 100, fine adjustment of the vertical and horizontal angles of the microphone 401 (fine adjustment of pan tilt) is easy. become.

  On the other hand, a male screw that is screwed into a microphone holder 402 that holds the microphone 401 is passed through the through hole 102 of the base 100, and the male screw and the microphone holder 402 are screwed together so that the microphone holder 402 is attached to the base 100. When fixed, the microphone holder 402 can be moved along the through hole 102 in the circumferential direction of the base 100. Accordingly, the position of the microphone 401 in the circumferential direction of the base 100 can be adjusted in addition to the adjustment of the vertical and horizontal angles of the microphone 401 while the posture of the base 100 is fixed.

  In this way, the position and posture of the microphone 401 can be adjusted while the posture of the base 100 is fixed, and the microphone 401 can take sounds from all directions.

  For example, six microphone holders 402 are fixed to the upper surface side of the base 100, and each microphone holder 402 holds the microphone 401.

  The microphone holder 402 can also be fixed to the bottom surface side of the base 100. In this case, the microphone 401 is held on the bottom surface side of the base 100. Therefore, since the microphones 401 can be disposed on the upper surface side of the base 100 and the bottom surface side of the base 100, more microphones 401 can be disposed and the orientation of the microphones 401 can be adjusted more widely.

  The cable 403 of the microphone 401 held by the microphone holder 402 is passed through the cable through hole 103. In this way, the entire center of gravity can be set closer to the center of the base 100. As a result, even if a large number of microphones 401 are arranged, it can be made more stable.

  When the base 100 is supported by the camera tripod 404, the male screw of the camera tripod 404 is screwed into the female screw of the support 104, and the base 100 is fixed to the camera tripod 404. When the base 100 is supported by the microphone stand 405, the male screw of the microphone stand 405 is screwed into the female screw of the support 104, and the base 100 is fixed to the microphone stand 405.

  Since the base 100 is fixed to the camera tripod 404 or the microphone stand 405 by the standardized screws, the base 100 and the camera tripod 404 or the microphone stand 405 can be easily attached and detached.

  Further, when the base 100 is supported by the camera tripod 404, the height of the base 100 can be adjusted, and the base 100 can be easily panned and tilted.

  As shown in FIG. 10, more microphones 401 can be arranged on one base 100. For example, as shown in FIG. 10, if 12 microphone holders 402 are fixed to the base 100, 12 microphones 401 can be arranged on one base 100.

  When more microphones 401 are arranged, the cable 403 can be easily handled by using the base 100 provided with the cable through hole 201.

  By providing the cable through hole 103, the cable through hole 201, and the cable through hole 301, the microphone 401 can be disposed on the base 100 with the elevation angle of the microphone 401 being increased.

  This will be described using the cable through hole 301 as an example.

  FIG. 11 is a diagram for explaining prevention of interference between the base 100 and the microphone 401 by the cable through hole 301.

  For example, if the elevation angle of the microphone 401 held by the microphone holder 402 is increased (when tilted greatly) from the downward direction to the horizontal direction and from the horizontal direction to the upward direction, the rear end of the microphone 401 (portion into which the cable 403 is inserted) is The position is lower than the upper surface of the base 100. If the cable through hole 301 is not provided, the rear end of the microphone 401 interferes with the upper surface of the base 100, and the adjustment range of the microphone 401 in the elevation angle direction becomes narrow.

  However, as shown in FIG. 11, by providing the cable through hole 301, interference between the rear end of the microphone 401 and the upper surface of the base 100 is prevented. As a result, the adjustment range in the elevation direction of the microphone 401 is widened, and the microphone 401 can be disposed on the base 100 in a state where the elevation angle of the microphone 401 is increased. That is, the degree of freedom of the posture of the microphone 401 increases.

  In particular, the cable through hole 301 has a width that allows a male screw to be screwed into a microphone holder that holds the microphone to pass through on the peripheral side of the base 100, has a shape of a long hole that extends from the periphery toward the center, and has a larger opening. Since it is connected to the portion, the microphone holder 402 can be slid to a position closer to the large opening portion and fixed to the position closer to the large opening portion. This further widens the adjustment range of the microphone 401 in the elevation direction. As shown in the lower side of FIG. 11, the elevation angle of the microphone 401 can be made substantially perpendicular to the upper surface of the base 100, and even when the base is arranged so that the upper surface of the base 100 is horizontal, the microphone 401. Can be directed straight up or straight down.

  In addition, an object other than the microphone holder 402 can be fixed to the fixing hole 101 or the through hole 102 as necessary.

  For example, conventionally, in order to place the microphone 401 at a low position, that is, at a position where the distance from the floor is short, the short camera tripod 404 or the short microphone stand 405 has to be used. However, most of the short camera tripod 404 or the microphone stand 405 is structurally weak, and the microphone 401 cannot be stably disposed.

  Therefore, for example, as shown in FIG. 12, the three legs 701 are fixed to the fixing hole 101 or the through hole 102. For example, the legs 701 are made of wood, resin, or metal. For example, the length of the leg 701 is shorter than the diameter of the base 100. More preferably, the length of the leg 701 is shorter than the radius of the base 100.

  When the leg 701 is fixed to the through hole 102, the position of the leg 701 with respect to the base 100 can be freely adjusted.

  By doing so, the base 100 on which a large number of microphones 401 are arranged can be stably and disposed at a low position. As a result, the sound from the low angle can be freely taken.

  The number of legs 701 may be four or more. When the number of legs 701 is three, rattling between the floor and the legs 701 can be prevented. When the number of legs 701 is four or more, a large number of microphones 401 can be arranged, and the base 100 can be stably arranged even when the total weight increases.

  Further, if a large number of microphones 401 are arranged on one side of the base 100, the position of the center of gravity is biased.

  Therefore, as shown in FIG. 13, when the microphone 401 is arranged on one side of the base 100, the weight 721 is fixed in the fixing hole 101 or the through hole 102 on the opposite side of the microphone 401. As a result, the position of the entire center of gravity can be adjusted to the center of the base 100, and the base 100 can be made to stand stably even if it is fixed to the microphone stand 405.

  The weight 721 may be a dedicated one, but the leg 701 may be used as the weight 721.

  Furthermore, the position where the microphone 401 is disposed can be outside the base 100 using a jig.

  FIG. 14 is a view showing the extension jig 741. The extension jig 741 is formed in a T shape with metal or the like. A fixing hole 742-1 to a fixing hole 742-3 are provided in a portion where the extension jig 741 is wide. For example, each of the fixing holes 742-1 to 742-3 is provided at a position where the wide portion of the extension jig 741 is divided into three in the width direction.

  The fixing holes 742-1 to 742-3 are arranged on a straight line or arranged according to the curvature of the through hole 102.

  A fixing hole 743 is provided at the tip of the narrow portion of the extension jig 741. A portion where the width of the extension jig 741 is narrow can be set to an arbitrary length.

  As shown in FIG. 15, the male screw is passed through the fixing hole 101 or the through hole 102 and each of the fixing holes 742-1 to 742-3, and the male screw is screwed into the male screw, thereby extending the male screw. A jig 741 is fixed to the base 100.

  For example, when the fixing holes 742-1 to 742-3 are arranged on a straight line, two of the fixing holes 742-1 to 742-3 and the fixing hole 101 or the through hole 102 are externally threaded. Then, the extension jig 741 is fixed to the base 100 by screwing the female screw into the male screw.

  For example, when the fixing holes 742-1 to 742-3 are arranged in accordance with the curvature of the through hole 102, the extension jig 741 is passed through the male screws through all the fixing holes 742-1 to 742-3. It can be fixed to the base 100.

  A male screw that is screwed into the microphone holder 402 that holds the microphone 401 is passed through the fixing hole 743 of the extension jig 741 fixed to the base 100 in this way, and the male screw and the microphone holder 402 are screwed together. Thus, the microphone holder 402 is fixed to the extension jig 741.

  Thus, by using the extension jig 741, the position where the microphone 401 is disposed can be outside the base 100. As a result, the microphone 401 disposed on the base 100 and the microphone 401 disposed on the extension jig 741 can be separated by an arbitrary distance.

  Further, as shown in FIG. 16, a plurality of bases 100 are coupled to each other in a multistage structure with legs 701, and microphones 401 are arranged on each base 100 so that the microphones 401 can be arranged vertically. Thus, the degree of freedom of arrangement of the microphone 401 can be increased. In this case, the leg 701 serves as a support for connecting the plurality of bases 100.

  In this case, the leg 701 can be shifted along the circumference of the base 100.

  Although the base has been described as a circular flat plate, the present invention is not limited to this, and the base may be formed into a polygonal flat plate having an arbitrary number of corners such as a triangle or a quadrangle.

  FIG. 17 is a diagram showing a base according to still another embodiment of the present invention. The base 801 is formed in a hexagonal flat plate shape. As in the case shown in FIG. 6, the same reference numerals are given to the portions, and description thereof is omitted.

  In the example shown in FIG. 17, each of the through holes 102 is provided along the circumference of the base 100 along one side. The cable through hole 802 penetrates from the upper surface to the bottom surface of the base 100. For example, each of the cable through holes 802 has a substantially triangular shape located inside a triangle formed by a line and a side connecting each vertex and the center of the hexagon.

  By providing the cable through hole 802, the base 801 can be thinned, the weight of the base 801 can be further reduced, and the degree of freedom of arrangement of the microphone 401 can be increased.

  Thus, a plurality of microphones can be arranged on one base. Conventionally, when a plurality of microphones are used, the number of microphone stands corresponding to the number of microphones is required. However, by using the base of the present invention, a large number of microphones can be arranged with a smaller number of microphone stands.

  Moreover, since it can be formed lightweight by removing the meat, it is convenient to carry.

  By using this base, the posture and position of the microphone can be freely determined. Specifically, not only can the microphone be placed at a high position or a low position, but the up / down / left / right angles (pan and tilt adjustment) of the microphone and the distance between the microphones can be freely determined. become.

  That is, the microphone can be arranged with many degrees of freedom.

  The center of gravity can be adjusted even when the microphones are intensively arranged on one side, such as when the sound from one direction is directed toward multiple microphones, so that the microphones can be stably placed. Can do.

  As described above, holes are formed along the circumference that are formed into a flat plate and threaded into the microphone holder that holds the microphone, so that a large number of microphones can be stably attached with many degrees of freedom. Can be placed.

  In addition, you may make it arrange | position other apparatuses, such as a video camera or a digital still camera, not only a microphone.
