JP5887205B2 - Tilt system for audio equipment - Google Patents

Description

The present invention relates to a tilting system for audio equipment that is used indoors in order to improve sound quality as well as earthquake countermeasures for audio equipment .

  The earthquake-resistant band of Patent Document 1 has a hook 4 at both ends, and at least a part of each tensile portion following the hook is a single band (7, 26) of the elastic member 6, respectively. The elastic member 6 is formed of a single strip (8, 27) made of a flexible cloth having a length longer than that of the belt 7 and having a tensile strength greater than that of the elastic member. Even if a single band (7, 26) of the elastic member is broken due to shaking, the flexible band (7, 26) can be fixed (reference numeral is that of Patent Document 1).

  This earthquake-resistant band can fix a computer, a monitor or the like to an office desk, and even if a part of the elastic band 6 (7, 26) is cut due to an unexpected accident such as an earthquake, the flexible band (7 26) provide immediate support, and there is an advantage that computers and computer-related equipment do not easily fall over.

  However, since the earthquake-resistant band of Patent Document 1 has (a) the hooks 4 at both ends, the engagement holes for the hooks 4 are formed at the left and right ends of one computer support base member (receiving member). The point that must be. (B) Since the entire inner peripheral surface of the belt-like elastic member 6 is simply surrounded in a surface contact state with respect to the left and right side walls and the upper wall of the box computer, For example, the second support member is provided in two rows with respect to the first support band member so that the upper part does not swing from side to side, and the configuration becomes complicated. (C) Contact of the seismic band with the box computer Therefore, there is a problem that the seismic band cannot be used for preventing the tilting of the acoustic device because it is unsuitable for the acoustic device that generates sound. In Patent Document 1, there is no description that the earthquake-resistant band can be used for preventing the tilting of the audio equipment.

The intended purpose of the present invention is to improve the sound quality together with earthquake countermeasures for the acoustic equipment , and to easily apply the tension of the elastic fastening band from above to the upper surface (downward) of the flat portion of the receiving member. It can be multiplied. The second purpose is to be inexpensive.

Tilting system audio equipment of the present invention, the receiving member, a box-type audio equipment, a tilting system for acoustic devices, including acoustic clamping band and the resistor, the acoustic device that is mounted on the receiving member, wherein The elastic fastening band is attached to the left side wall, the upper wall, and the right side wall of the audio device so as to wind at least “one round”, and includes left and right side walls of the audio device. And a pair of left and right resistors respectively interposed at either the left or right central portion or the lower end portion of the elastic fastening band, and the left and right portions of the elastic fastening band are symmetrically removed against the elastic force. It is characterized by being expanded and displaced.

  In the above configuration, the left and right resistor pairs of the left and right resistors 6a are elastically displaced in a “U” shape when viewed from the front, while the right portion 6b is the left portion 6a. It is characterized in that it is elastically displaced in a “reverse, square shape” symmetrically.

(A) Since the invention according to claim 1 can easily apply the tension of the elastic tightening band from above to the upper surface of the flat portion of the receiving member together with its own weight, the invention according to claim 1 can be used together with earthquake countermeasures for the acoustic equipment. The sound quality can be improved. Also, each member can be easily mounted. Furthermore, it is inexpensive because it uses only an elastic fastening band and a plurality of resistors.
(B) Since the invention according to claim 2 can support the portions near the lower end portions of the left and right side walls of the acoustic device with good balance, the acoustic device does not easily tilt.

An embodiment in which the main part is included as it is and one resistor is added. An embodiment in which the main part is included as it is and two resistors are added.

  First, reference numeral 1 denotes a receiving member for audio equipment. The receiving member 1 includes, for example, a rectangular base plate 2 with or without casters (not shown) as shown in FIG. A plurality of or a single column (in this embodiment) of columns 3 fixed at the lower end thereof, and a rectangular flat portion 4 of which the center of the lower surface is fixed to the upper end of the column 3. The flat part 4 is formed smaller than the base plate 2.

  Next, 5 is a vertically long box-shaped acoustic device (speaker) described on the upper surface 4a of the flat portion 4 of the receiving member 1. As is well known, the acoustic device 5 has an unnumbered tweeter or woofer, so-called. It is a vibration generator that generates sound by driving a diaphragm by an input signal from an amplifier.

  Here, when reference numerals are given to the respective walls of the audio device 5 with reference to FIG. 1, 5a is a bottom wall, 5b is a left wall, 5c is a right wall, and 5d upper wall.

  Next, 6 is a string or belt-like elastic fastening band, and in this embodiment, it is formed in an endless and belt-like manner, for example, as a rubber band, as shown in FIG. A part or all of the belt-like elastic fastening band 6 is elastic. When a part of the belt-like elastic fastening band 6 is elastic, the other part is, for example, a non-stretchable cloth.

  When the elastic fastening band 6 is endless and band-shaped, it is necessary to apply tension so that the acoustic device 5 is always pressed against the upper surface 4a (downward) of the flat portion 4 of the receiving member 1 from above. In consideration of the size of the outer peripheral shape and the size / thickness of the flat portion 4 of the receiving member 1, the inner diameter (the size of the ring) is appropriately set including the material. As for the material, natural rubber, chloroprene acrylo rubber, nitrile butadiene rubber, silicon rubber and other rubber materials and polyethylene materials can be used.

  In the present embodiment, in consideration of sound quality, a polyethylene material, for example, an endless one having a width of about 9 mm to 15 mm is used.

  Thus, when used, the elastic fastening band 6 allows the box-shaped acoustic device 5 placed on the upper surface 4a of the flat portion 4 of the receiving plate member 1 to be attached to the receiving member 1 as shown in FIGS. The lower surface 4b of the flat part 4 is included, and the sound device 5 is mounted so as to be wound around the left wall 5b, the upper wall 5d, and the right wall 5c. Then, as described above, the acoustic device 5 is entirely surrounded by the elastic fastening band via the flat portion 4, and as a result, the elastic force (tension) of the elastic fastening band is the upper surface 4 a of the flat portion 4. It takes.

  By the way, the portion around which the acoustic device 5 is wound may be a substantially central portion as shown in FIG. 3, but may be either the front portion or the rear portion, or both. When both the front part and the rear part of the wall surface of the acoustic device 5 are tightened, as a matter of course, it is necessary to use “a total of two elastic tightening bands 6”.

  Next, 7 is a three-dimensional hard resistor, and the resistor 7 is formed in a rectangular parallelepiped shape like an eraser, for example, as shown in FIG. Of course, the form of the resistor 7 is not limited to this, and may be formed in a cylindrical body, a rectangular parallelepiped, a polygonal column, a base, a cylindrical body, or the like. The hard resistor 7 is made of metal, hard rubber, wood, hard synthetic resin, or the like, and is formed like a dice, for example.

  The resistor 7 of the present embodiment has a tip end surface 7a that is a vertical surface and is a member that stably comes into surface contact with the left and right side walls 5b (5c) of the acoustic device 5, and therefore desirably does not affect the sound quality. Thus, it is preferable to use a small one, that is, a width that is substantially the same as or smaller than the width of the elastic fastening band 6.

  Thus, when used, the pair of left and right resistors 7 and 7 are elastically tightened with a portion near the center or lower end of the left and right side walls 5b and 5c of the acoustic device 5 as shown in FIG. The left and right portions 6a and 6b are respectively sandwiched between the left and right portions 6a and 6b of the band 6, and the left and right portions 6a and 6b are separated from the left and right side walls 5b and 5c of the opposing acoustic device 5 as a whole. As shown in FIG. In the embodiment, the left portion 6a is elastically displaced in a “U” shape, while the right portion 6b is elastically displaced in a “reverse, U” shape symmetrically to the left portion 6a. . In other words, the left and right portions 6a and 6b of the elastic fastening band 6 are opened symmetrically from the left and right side walls 5b and 5c of the acoustic device 5 (non-contact state).

  Here, how the acoustic device 5 is supported on the flat portion 4 of the receiving member 1 through the elastic fastening band 6 will be described with reference to FIG. First, point A and point B are the lower end portions of the left and right portions 6a and 6b of the belt-like elastic fastening band 6 that are symmetrically supported by the engaging grooves 8 and 8 of the rear end surfaces 7b and 7b of the left and right resistors 7 and 7, respectively. It is a close part. Next, points C and D are the left and right lower corners of the flat portion 4 of the receiving member 1. Furthermore, points E and F are the left and right upper corners of the acoustic device 5. Accordingly, the acoustic device 5 is supported symmetrically at a total of six locations from above to below via the elastic fastening band 6.

  Therefore, when comparing the lengths of the left and right portions 6a and 6b of the elastic fastening band 6 supported in a total of six places in the embodiment, “left side L1 = right side L1” and “left side L2 = right side L2”. It is. In the embodiment, the left and right resistors 7 and 7 are disposed at portions near the lower end portions of the left and right side walls 5b and 5c of the acoustic device 5, and therefore both the left and right are "L1 <L2." Further, the flat portion 4 of the receiving member 1 is subjected to the tension of the elastic fastening band 6 and the gravity G of the acoustic device 5.

  Next, with reference to FIGS. 6 to 8, the tilt preventing action of the acoustic device 5 will be described. In an ordinary general use mode, the acoustic device 5 is supported symmetrically in a total of six places via the elastic fastening band 6, but in the embodiment, the left and right portions 6a of the elastic fastening band 6 are further provided. Since a pair of left and right piece-like resistors 7, 7 are interposed between 6b and the left and right side walls 5b, 5c of the acoustic device 5, as shown in FIG. A point and B point "and" C point and D point which are the left and right lower corners of the flat portion 4 of the receiving member 1 "are supported in an inverted trapezoidal shape in a total of four places.

  Therefore, the explanation will be made assuming that a large earthquake occurs. When the acoustic device 5 rolls to the left and right and tilts when a large earthquake occurs, when one of the left and right portions 6a and 6b of the elastic fastening band 6 extends, the other loosens. Although FIG. 8 illustrates exaggeratedly for convenience of explanation, for example, if the audio device 5 is tilted to the right side, the left side L1 of the left part 6a extends against the elastic force, whereas the right side L1 of the right part 6b is Shrink. At this time, the left portion 6a of the elastic tightening band 6 is partitioned by the point A of the resistor 7 from the tension applied to the upper E point and the lower C point. In other words, only L1 on the left side between the points A and C instantly expands and contracts.

  Therefore, the embodiment can far more effectively prevent tilting than the acoustic device 5 is surrounded by the four points of C point, E point, F point, and D point.

  By the way, the sound quality effect will be described. When the tension of the elastic tightening band 6 is applied to the acoustic device 5 through the elastic tightening band 6 from the upper side to the lower side along with its own weight as in the embodiment, it is a technical story. , "Jump up and down of the audio equipment" is reduced, and the sound quality is improved.

  In addition, when the elastic tightening band 6 is not present, “sound is heavy”, and when the elastic tightening band 6 is present as in the embodiment, “the sound is noise-removed, It feels like a crisp and clear sound. Therefore, in the embodiment, it is possible to simultaneously improve the sound quality as well as prevent the tilting.

  In the first embodiment, when the resistor 7 is mounted, the resistor 7 is simply mounted by fitting the left and right resistors 7 in a sandwich state after the endless elastic fastening band 6 is mounted. be able to.

  Next, another embodiment shown in FIGS. 9 to 13 will be described. Hereinafter, other embodiments are referred to as a second embodiment and a third embodiment for convenience. In the description of the second embodiment and the third embodiment, the same parts as those in the first embodiment are denoted by the same or similar reference numerals, and redundant descriptions are omitted.

  9 and 10 show a second embodiment using an endless elastic fastening band 6A. That is, the second embodiment is mainly different from the first embodiment in that an elastic fastening band 6A having both end portions is used. When the non-endless elastic fastening band 6A is used as described above, it is common to have a buckle 9 as a stopper at one end, but, of course, without providing the buckle 9 at one end, A belt-like elastic tightening band main body and a stopper separate from the elastic tightening band main body may be used. In short, as shown in FIG. 9, a pair of left and right ends using the endless elastic fastening band 6A and an integral or separate stopper, and between the elastic fastening band 6A and the left and right side walls of the acoustic device 5 are used. If the resistor 7 is interposed to prevent tilting and improve the sound quality at the same time, the range of the present invention is entered.

11 to 13 show a second embodiment in which another resistor 7A is used in order to improve sound quality. In the second embodiment, either the endless elastic fastening band 6 of the first embodiment or the endless elastic fastening band 6A of the second embodiment may be used.
This third embodiment is mainly different from the first embodiment in that the resistor 7A is an improved version of the “vibration prevention support device (Japanese Patent Application No. 2010-41641)” proposed by the applicant of the Japan Patent Office. It is used.

  In each figure, the resistor 7A is composed of two articles 11 and 12. One is a cylinder having a vertical rear end 7b pressed by the inner surface of the elastic fastening band 6 (6A), for example, a square cylinder 11, and the left and right side walls 5b of the acoustic apparatus 5 that are fitted inside the square cylinder 11 and inside. 5c, and a corner plate 12 abutting on the surface of the corner plate 12 in a surface contact state. A corner or cone-shaped projection portion 13 is formed continuously at a substantially central portion of the rear end surface of the corner plate 12, and the tip of the projection portion 13 is The rectangular tube 11 is supported by a recess 14 formed at the center of the inner wall surface of the vertical rear end 7b.

  By the way, about the form of the square cylinder 11 and the square board 12, for example, forming the square cylinder 11 in a cylindrical shape, forming the square board 12 in a disk shape, and the like are equivalent matters. Moreover, in each embodiment of this invention, you may provide the contact bonding layer which has a release paper in the front end surface 7a of a resistor (7, 7A). Furthermore, a total of four resistors 7A (including the vibration preventing support device described in Japanese Patent Application No. 2010-41641) are interposed between the bottom wall 5a of the acoustic device 5 and the upper surface 4a of the flat portion 4 of the receiving member 1. Is also good (use invention).

  Further, for example, as shown in FIGS. 14 and 15, one or two resistors (7, 7 A) are received in a state of being interposed in the lower surface of the flat portion 4 of the member 1 or the upper wall 5 d of the acoustic device 5. The receiving member 1 may include a lower surface 4b of the flat portion 4 and may be mounted so as to be wound at least “one round” around the left side wall 5b, the upper wall 5d, and the right side wall 5c of the acoustic device 5. In other words, the endless elastic fastening band 6A may be "two rounds" (utilization invention).
