A speaker having a hole, a first long hole and a second long hole that communicate with the circular hole and through which the shaft portion of the screw passes, and a mounting surface including the circular hole, the first long hole, and the second long hole The first long hole edge of the mounting surface that defines the first long hole and the first long hole corresponding to the vertical arrangement of the cabinet and the second long hole corresponding to the horizontal arrangement are provided so as to be substantially orthogonal to each other. And the second long hole edge of the mounting surface that defines the second long hole, the separation distance D1 to D2 from the back surface is larger on the top surface side than the bottom surface side of the speaker cabinet in the vertical or horizontal arrangement, respectively. Tilt to do.

  In the speaker cabinet of the present invention, the first long hole edge and the second long hole edge have a separation distance D0 from the back surface of the first direction in which the first long hole extends and the second direction in which the second long hole extends. It is formed in the attachment surface which forms the recessed part which inclines so that it may change along the 45 degree direction which is an intermediate direction of this, and was depressed from the back surface.

  Preferably, in the speaker cabinet of the present invention, a plurality of wall surface mounting mechanisms are provided on the back surface, and any one of the long holes provided in each wall surface mounting mechanism is arranged in parallel to each other.

  A speaker system of the present invention includes the above speaker cabinet and a speaker attached to the speaker cabinet.

  Hereinafter, the operation of the present invention will be described.

  The speaker cabinet of the present invention includes a wall surface attachment mechanism that is attached with the back surface closely attached to the wall surface. The wall surface mounting mechanism includes a circular hole through which a screw head of a screw that projects by screwing into a wall surface passes, a long hole that communicates with the circular hole and engages a shaft portion of the screw, and a circular hole and a long hole. Including a mounting surface. Alternatively, the wall surface mounting mechanism includes a circular hole through which a screw head of a screw that is screwed into the wall surface passes, and a first long hole and a second long hole that are in communication with the circular hole and through which the shaft portion of the screw passes. A mounting surface including a circular hole, a first long hole, and a second long hole. The first long hole is a long hole corresponding to the vertical arrangement of the speaker cabinet, and the second long hole is a long hole corresponding to the horizontal arrangement, and these are provided so as to be substantially orthogonal.

  Preferably, the speaker cabinet is provided with a plurality of wall surface mounting mechanisms on the back surface, and constitutes a speaker system that is mounted with the back surface in close contact with the wall surface together with the speaker mounted on the speaker cabinet. Therefore, the speaker system of the present invention is designed so that the screw to be screwed into the wall surface enters the circular hole and the long hole of the mounting surface provided on the back surface of the speaker cabinet, so that no special bracket or the like is required. The back surface can be attached to the wall surface.

  Specifically, in the wall surface mounting mechanism of the present invention, the long hole edge portion of the mounting surface that defines the long hole is inclined so that the separation distance D from the back surface is larger on the top surface side than the bottom surface side of the speaker cabinet. To do. Alternatively, the first long hole edge portion of the mounting surface that defines the first long hole and the second long hole edge portion of the mounting surface that defines the second long hole respectively have a separation distance D1 to D2 from the back surface. Inclined so as to be larger on the top side than the bottom side of the speaker cabinet in the vertical or horizontal arrangement.

You may form in the attachment surface which forms the recessed part which inclines so that it may change along a degree direction and was depressed from the back surface.

  That is, in the wall surface mounting mechanism of the present invention, the long hole that communicates with the circular hole and through which the shaft portion of the screw passes is inclined so that the separation distance from the back surface is larger on the top surface side than the bottom surface side of the speaker cabinet. Therefore, when mounting the back of the speaker cabinet in close contact with the wall surface using screws that are screwed so as to protrude on the wall surface, the screw head and shaft section should be within a certain range. Can be engaged with any part of the inclined long hole edge to absorb the variation in the protruding dimensions of the screw. When the speaker system is installed on a vertical wall, gravity acts on the speaker cabinet, so the screw head and shaft are relatively close to each other so that there is no gap between the back and the wall.

  Hereinafter, a speaker cabinet and a speaker system using the same according to preferred embodiments of the present invention will be described, but the present invention is not limited to these embodiments.

  FIG. 1 is a diagram illustrating a speaker system 1 according to a preferred embodiment of the present invention. Specifically, FIG. 1A is a perspective view of the speaker system 1 attached to the wall surface 4 as viewed from the front side, and FIG. 1B is a perspective view of the speaker system 1 as viewed from the back side. is there. In FIG. 1, a part of the configuration of the speaker system 1 that is not necessary for the description is omitted.

  The speaker system 1 according to this embodiment includes a speaker unit 2 and a cabinet 3 to which the speaker unit 2 is attached. In this embodiment, the speaker unit 2 is attached to the front surface 3f of the cabinet 3, and when an audio signal current is supplied, the speaker diaphragm oscillates in the front-rear direction to emit sound waves. The substantially rectangular parallelepiped cabinet 3 separates the front and rear spaces of the speaker diaphragm and defines the acoustic capacity therein. For example, the cabinet 3 formed of resin is configured by connecting a front portion including a front surface 3f and a rear portion including a back surface 3r.

  In addition, the cabinet 3 can be attached to the vertical flat wall surface 4 with the flat back surface 3r using an inexpensive screw 5 (not shown in FIG. 1) without requiring a special bracket or the like. In addition, the rear surface 3r has a wall surface mounting mechanism. In the wall surface mounting mechanism of the cabinet 3 of the present embodiment, the mounting surface 6 that forms a concave portion recessed from the back surface 3r is provided on the upper side of the center of the back surface 3r, and the rectangular parallelepiped speaker system 1 is vertically long. In the vertically arranged state, the back surface 3r of the cabinet 3 can be attached to the wall surface 4 in close contact.

  FIG. 2 is a cross-sectional view for explaining a wall surface mounting mechanism of the cabinet 3 of the present embodiment constituting the speaker system 1. FIG. 2A and FIG. 2B are explanatory views in the case where the lengths of the screws 5 screwed into the wall surface 4 are almost different from each other. The wall surface mounting mechanism provided in the cabinet 3 includes a circular hole 7 through which the screw head 5a of the screw 5 protruding by screwing into the wall surface 4 passes, and a length through which the shaft portion 5b of the screw 5 passes through the circular hole 7. It has a hole 8 and a mounting surface 6 including a circular hole 7 and a long hole 8. The long hole 8 is formed in the mounting surface 6 so as to extend from the circular hole 7 in the upward direction in the vertical arrangement corresponding to the speaker system 1 in the vertical arrangement. And the long hole edge part of the attachment surface 6 which prescribes | regulates the long hole 8 inclines so that the separation distance D with the back surface 3r may become large in the top | upper surface side rather than the bottom face side of the speaker cabinet 1. FIG.

  Accordingly, as shown in FIGS. 2A and 2B, the screw head 5a of the screw 5 enters the inside of the cabinet 3 through the circular hole 7, and the screw head of the screw 5 is shown. Since the 5a and the shaft portion 5b engage with any part of the edge of the long hole of the mounting surface 6 that defines the long hole 8, the variation in the protruding dimension of the screw 5 can be absorbed. In the wall surface mounting mechanism, the long hole 8 communicating with the circular hole 7 and through which the shaft portion 5b of the screw 5 passes is inclined so that the separation distance D from the back surface is larger on the top surface side than the bottom surface side of the cabinet 3. Therefore, when the back surface 3r of the cabinet 3 is attached in close contact with the wall surface 4 using the screws 5 that are screwed so as to protrude to the wall surface 4, if the projecting dimensions of the screws 5 are within a certain range, the screws The head portion 5a and the shaft portion 5b can be engaged with any one of the inclined long hole edges, and variations in the protruding dimensions of the screw 5 can be absorbed. When the speaker system 1 is installed on a vertical wall, gravity acts on the cabinet 3, so that the head 5 a and the shaft 5 b of the screw 5 are in close contact with each other so that there is no gap between the back 3 r and the wall 4. It moves relative to the fixed position and is fixed. As a result, the speaker system 1 including the wall surface mounting mechanism of the present embodiment has a good appearance and can be stably fixed to the wall surface 4.

  FIG. 3 is a cross-sectional view illustrating a wall surface mounting mechanism of a cabinet 30 of a comparative example that constitutes the speaker system 1 in place of the cabinet 3. FIG. 3A and FIG. 3B are explanatory diagrams in the case where the lengths of the screws 5 screwed into the wall surface 4 are substantially different from each other. The wall surface mounting mechanism provided in the cabinet 30 of the comparative example includes a circular hole 37 through which the screw head 5a of the screw 5 protruding by screwing into the wall surface 4 passes, and a shaft portion 5b of the screw 5 communicating with the circular hole 37. It is common to the cabinet 3 of the previous embodiment in that it has a long hole 38 that passes therethrough. However, in the cabinet 30 of the comparative example, the circular hole 37 and the long hole 38 are provided in the back surface 30r, and a recess recessed from the back surface 3r as in the previous embodiment is formed and provided to be inclined. Does not have a mounting surface. The long hole 38 is formed in the back surface 30r so as to extend from the circular hole 37 in the upward direction in the vertical arrangement corresponding to the speaker system 1 in the vertical arrangement.

  Therefore, when the length of the screw 5 screwed so as to protrude to the wall surface 4 is appropriately adjusted as shown in FIG. 3A, the screw head 5a of the screw 5 is a circular hole. 37, the shaft portion 5b of the screw 5 engages with the end portion of the long hole edge defining the long hole 38, so that the cabinet 30 of the comparative example has the rear surface 30r on the wall surface 4. Can be attached in close contact. However, when the length of the screw 5 screwed so as to protrude to the wall surface 4 is adjusted to be longer than an appropriate state as shown in FIG. The speaker system 1 attached to the wall surface 4 does not look good and becomes unstable as shown in the case of FIG. 3B because it does not have a function of absorbing the variation in the protruding dimension of the screw 5.

  In the wall surface mounting mechanism of the cabinet 3 of the present embodiment, the circular hole 7 and the long hole 8 are formed by providing a keyhole-shaped through hole in the mounting surface 6 having a substantially constant inclined thickness. Thus, when the attachment surface 6 is inclined so that the separation distance D from the back surface 3r is larger on the top surface side than the bottom surface side of the speaker cabinet, the attachment that defines the long hole 8 is provided. The thickness of the long hole edge of the surface may be constant. In the case of the present embodiment, the separation distance D between the long hole edge of the mounting surface 6 and the back surface 3r is a dimension including the step between the back surface 3r and the mounting surface 6 and the thickness of the mounting surface 6.

  On the other hand, for example, even if the mounting surface 6 constituting the wall surface mounting mechanism is formed as a surface substantially parallel to the back surface 3r of the cabinet 3, the long hole edge portion of the mounting surface 6 defining the long hole 8 has a long hole. A rib having a convex shape may be provided inside the cabinet 3 corresponding to the shape, and the thickness thereof may gradually change along the long hole 8. That is, the separation distance D between the long hole edge portion of the mounting surface 6 and the back surface 3r is such that the thickness of the mounting surface 6 or the long hole 8 is determined even when there is almost no step between the back surface 3r and the mounting surface 6. What is necessary is just a dimension including the height of the rib provided in the slot hole edge to prescribe | regulate. In the case of the embodiment, the long hole edge portion of the mounting surface 6 that defines the long hole 8 is inclined so that the separation distance D from the back surface 3r is larger on the top surface side than the bottom surface side of the speaker cabinet 3. Thus, the screw head 5a and the shaft portion 5b can be engaged with any one of the inclined long hole edges, and the variation in the projecting dimension of the screw 5 can be absorbed. The speaker system 1 including the wall surface mounting mechanism has a good appearance and can be stably fixed to the wall surface 4.

  FIG. 4 is a diagram illustrating a cabinet 13 constituting a speaker system 1 according to another preferred embodiment of the present invention. Specifically, FIG. 4A is a perspective view of the cabinet 13 viewed from the front side, and FIG. 4B is a perspective view of the cabinet 13 viewed from the back side. In FIG. 4, a part of the configuration of the cabinet 13 that is not necessary for description is omitted. The cabinet 13 of this embodiment constitutes the speaker system 1 in place of the cabinet 3 of the previous embodiment. Accordingly, parts and members that are common to those in the previous embodiment are assigned common numbers, and descriptions thereof are omitted.

  The cabinet 13 according to the present embodiment can be mounted on the plane rear wall 13r on the vertical plane wall 4 using an inexpensive screw 5 (not shown in FIG. 4) without requiring a special bracket or the like. The rear surface 13r has a wall surface mounting mechanism so that it can be made. In the wall surface mounting mechanism of the cabinet 13 of the present embodiment, the mounting surface 16 that forms a recess recessed from the back surface 13r is provided at the substantially center of the back surface 13r, and the rectangular parallelepiped speaker system 1 is vertically arranged. The rear surface 13r of the cabinet 13 can be attached to the wall surface 4 in close contact with the wall surface 4 either in a state or in a horizontally disposed state that is rotated approximately 90 degrees from the vertically disposed.

  The wall surface mounting mechanism provided in the cabinet 13 includes a circular hole 17 through which the screw head 5a of the screw 5 protruding by screwing into the wall surface 4 passes, and a shaft portion 5b through which the shaft 5b of the screw 5 passes through the circular hole 17. The first long hole 18 and the second long hole 19, and the mounting surface 16 including the circular hole 17, the first long hole 18, and the second long hole 19. The first long hole 17 provided in the x-axis direction illustrated corresponding to the vertical arrangement of the cabinet 3 and the second long hole 18 provided in the y-axis direction illustrated corresponding to the horizontal arrangement are the circular holes 17. And is provided as a through hole in the mounting surface 16 inclined so as to be substantially orthogonal.

  The mounting surface 16 has a distance D0 from the back surface 13r along the z-axis direction shown in the figure, which is an intermediate direction between the first long hole 17 and the second long hole 18, and the bottom surface of the speaker cabinet 1. It inclines so that it may become larger on the top side than the side. That is, the mounting surface 16 is inclined with respect to the back surface 13r along a 45-degree direction that substantially coincides with one of the diagonal lines of the mounting surface 16. Accordingly, the first long hole edge portion of the mounting surface 16 that defines the first long hole 18 and the second long hole edge portion of the mounting surface that defines the second long hole 19 are each separated from the back surface 13. It inclines so that D1 thru | or D2 may be enlarged in the top | upper surface side rather than the bottom face side of the cabinet 3 in vertical arrangement | positioning or horizontal arrangement | positioning. The separation distances D0, D1, and D2 defined by the mounting surface 16 are dimensions corresponding to the separation distance D in the previous embodiment.

  Therefore, as in the case of the previous embodiment, when the rectangular parallelepiped speaker system 1 is attached to the wall surface 4 in a vertically arranged state, the screw head 5a of the screw 5 is placed inside the cabinet 13 through the circular hole 17. The screw head 5a and the shaft portion 5b of the screw 5 are engaged with any one of the long hole edges of the mounting surface 16 that defines the first long hole 18 corresponding to the vertical position. The speaker system 1 can be fixed in a vertical arrangement after absorbing the variation in the protruding dimensions. Further, when the rectangular parallelepiped speaker system 1 is attached to the wall surface 4 in a lateral arrangement, the screw head 5a of the screw 5 enters the inside of the cabinet 13 through the circular hole 17, and the screw head 5a of the screw 5 and Since the shaft portion 5b engages with any part of the long hole edge portion of the mounting surface 16 that defines the second long hole 19 corresponding to the lateral position, the variation in the protruding dimension of the screw 5 is absorbed, The speaker system 1 can be fixed horizontally.

  When the speaker system 1 is installed on a vertical wall surface, gravity acts on the cabinet 13, so that the head portion 5 a and the shaft portion 5 b of the screw 5 are in close contact so that there is no gap between the back surface 13 r and the wall surface 4. It moves relative to the fixed position and is fixed. In this wall surface mounting mechanism, the mounting surface 16 provided with the first long hole 18 or the second long hole 19 that communicates with the circular hole 17 and through which the shaft portion 5 b of the screw 5 passes is provided in a vertical or horizontal arrangement of the cabinet 13. In any case, since it is inclined so that the separation distance D0 from the back surface 13r is larger on the top surface side than on the bottom surface side, the cabinet using screws 5 that are screwed so as to protrude to the wall surface 4 is used. When the back surface 13r of 13 is attached in close contact with the wall surface 4 and the protruding dimension of the screw 5 is within a certain range, the first long hole 18 or the second long hole in which the screw head portion 5a and the shaft portion 5b are inclined. It is possible to engage with any one of the 19 long hole edges to absorb the variation in the protruding size of the screw 5. As a result, the speaker system 1 including the wall surface mounting mechanism of the present embodiment has a good appearance and can be stably fixed to the wall surface 4.

  In the wall surface mounting mechanism of the cabinet 13 of the present embodiment, the long hole edge of the circular hole 7 and the first long hole 18 and the long hole edge of the second long hole 19 are arranged along the z direction shown in the drawing on the back surface 13r. Is formed by providing a through hole having a keyhole shape on the mounting surface 16 having a substantially constant thickness so as to change the separation distance D0. In this way, the mounting surface 16 is inclined so that the separation distance D0 from the back surface 13r is larger on the top surface side than on the bottom surface side of the cabinet 13 regardless of whether the mounting surface 16 is vertically disposed or horizontally disposed. In this case, the thickness of the long hole edge of the attachment surface that defines the long hole edge of the first long hole 18 and the long hole edge of the second long hole 19 may be constant.

  Of course, the long hole edge portion of the first long hole 18 and the long hole edge portion of the second long hole 19 correspond to the long hole edge portion of the mounting surface 16 that defines the respective long holes, and the cabinet 13 corresponds to the shape of the long hole. A rib that has a convex shape may be provided on the inside, and the thickness thereof may gradually change along the long hole. The screw head portion 5a and the shaft portion 5b can be engaged with any of the inclined long hole edges to absorb the variation in the protruding size of the screw 5. As a result, the wall surface mounting mechanism of this embodiment can be The provided speaker system 1 is good-looking and can be fixed to the wall surface 4 stably.
