Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a speaker unit and a method for mounting the same, and particularly to a speaker unit that is embedded in a wall of a building such as a concrete wall, and a method for mounting the same. Regarding the method.

(Prior art and its problems) In order to install a speaker unit consisting of a speaker and a speaker box embedded in the wall surface of a building, such as a partition wall, ceiling, or floor, a speaker box It is necessary to form four parts.

In order to form the recess for the speaker box on the wall surface, the recess formation process must be scheduled as an intermediate step during the wall surface formation, which is carried out several months before the completion of the construction work. It won't happen.

However, during this intermediate stage of construction work, it is often difficult to determine the specifications of the speaker units to be installed, and special formwork must be prepared to create such recesses. This complicates the construction work and may lead to incorrect work. Further, depending on the user of the building, there are cases where the use of the speaker unit is not necessary, and in such a case, there is a problem that the four parts provided on the wall surface must be filled again.

For this reason, the speaker unit is usually fixed to the wall in a protruding state, or after the construction is completed, a recess is formed in the wall according to the request, and the speaker unit is embedded in the recess.

However, fixing the speaker unit in a state where it protrudes from the wall surface is not aesthetically pleasing and also impedes space utilization. Furthermore, forming recesses after the completion of wall construction is difficult and causes an increase in costs, and there is also the problem that burying wiring cords is difficult.

The present invention has been made in consideration of these points,
To provide a speaker unit that can be installed embedded in a wall surface with easy construction and no erroneous work, and a method for installing the same.

(Means for Solving the Problems) In order to achieve the above objects, the present invention provides a speaker box that is installed embedded in the wall of a building, a speaker that is installed inside the speaker box, and a speaker that is installed in the speaker box. The speaker unit includes a mounting plate for fixing the speaker unit, and is characterized in that the speaker box is formed by a standardized switch box.

Further, according to the present invention, the speaker unit is prepared by preparing a standardized switch box, and when forming the wall surface of a building, forming a recess for the standard switch box and burying a hollow tube for wiring in the recess. Insert and fix the standard switch box with the opening facing outward, introduce the wiring cord into the standard switch box using the hollow wiring tube, and install and fix the speaker into the standard switch box using the mounting plate. At the same time, it is installed through each step of connecting the wiring cord to the speaker.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 and 2 are an exploded perspective view and a sectional view showing an example of a speaker unit installed according to the present invention. In the figure, numeral 11 is a speaker box,
This speaker box is constituted by a standard switch box of a predetermined standard such as a JIS standard product. A mounting plate 12 is fixed to the standard switch box 11 using mounting screws 13, and a speaker 14 is further fixed to this mounting plate 12 using mounting screws 15.

The standard switch box 11 is embedded and fixed in a recess 22 formed in a concrete wall 21 using screws 23 or the like. Further, a wiring hollow tube 24 for introducing a wiring cord (not shown) is connected to the standard switch box 11, and this wiring hollow tube 24 is
Concrete g! It is buried in 21.

A cover 16 is attached to the speaker 14, and the hook-shaped protrusions 18 protruding from the back surface of the cover 16 are inserted into the plurality of attachment holes 17 drilled in the attachment plate 12. It is fixed by

Next, we will explain how to mount a speaker unit with such a structure on a wall, as shown in Figure 3 Ca) and Figure 3 (
This will be explained using b).

First, a switch box 11 that is standardized according to public standards such as JIS standards or private standards such as corporate product standards is prepared. This switch box 11 has the shape and dimensions determined by the standard, and the box is installed using the screw holes 11.
81 cover mounting is provided with a screw hole 11b for
Connection boss 11C of wiring hollow tube 24 for introducing wiring cord
is provided. Standard switch box 1 like this
1 can be easily obtained from general construction-related parts shelves, and can be prepared, for example, at the construction site during the construction work with simple instructions.

When forming the wall surface of the building, a recess 22 corresponding to the shape and size of the switch box 11 is formed in the wall 21.

The formation of the four parts 22 can be performed in the same manner as in the case of embedding a normal switch box, and is performed by embedding a standard formwork in the wall and pouring concrete or the like. In this case, similar to the case of installing a normal switch box, the work of burying the wiring hollow tube 24 is performed at the same time.

Once this step has been completed, the switch box installation work will be completed and the construction work will proceed to the final stage. Basic construction work on the building has been completed.

At this stage, the prepared standard switch box 11 is inserted into the recess 22 with the opening facing outward, and fixed to the wall using screws 23 or the like. At this time, the connection boss 11c of the switch box 11 and the hollow wiring pipe 24 are connected (FIG. 3(a)).

In order to simplify the process, the switch box 11 is buried directly without using formwork when pouring concrete, etc.
It may also be used as a formwork. In this case, the wiring hollow tube 24 and the switch box 11 are embedded in the wall in a combined state.

Next, the mounting plate 12 to which the speaker 14 is fixed in advance with the screws 15 is fixed to the switch box 11 using the screws 13 and the screw holes 11b. At this time, the wiring cord is connected to the speaker 14. As a result, the speaker 14 is fixedly installed within the switch box 11 (FIG. 3(b)).

Subsequently, the cover 16 of the speaker is attached by inserting and engaging the projecting piece 18 into the mounting hole 17 of the mounting plate 12.

As a result of the above, the speaker unit is connected to the concrete wall 2.
It is installed embedded in 1.

As described above, according to the present invention, a standard switch box that is installed embedded in a wall surface in an intermediate process of construction work can be used as a speaker box. Thereby, the speaker unit can be easily installed embedded in the wall surface with relatively simple construction work. In addition, standard switch boxes are easy to prepare, so
It is also possible to embed the switch box at the construction site during the construction process, and construction workers are usually accustomed to handling switch boxes, so there are fewer problems during construction.

The speaker unit mounted in this manner has excellent strength because the switch box has sufficient strength and durability as a construction member. Furthermore, the design of the mounting plate for mounting the speaker can be easily done in accordance with the standard specifications for switch box covers.

Furthermore, since the hollow tube for wiring is buried in advance, wiring with the speaker is easy, and wall construction etc. are not required when installing the speaker unit.

Furthermore, if circumstances change and the speaker unit is not used, the recess can be covered with a commercially available standard decorative board, or it can be used as a normal switch box. Furthermore, by devising the shape of the mounting plate 12, it is possible to use it as both a switch box and a speaker box.

FIG. 4 is an exploded perspective view showing another embodiment of the present invention.

In this embodiment, a Velcro tape 31 for attaching the speaker cover 16 is attached to the attachment plate 12. A similar Velcro tape (not shown) is attached to the back surface of the cover 16, and the cover can be attached by simply pressing the cover 16 against the attachment plate 12.

Further, according to this embodiment, even if the switch box 11 is embedded in a somewhat oblique state, the mounting plate 12
This error can be accommodated by horizontally mounting the cover 16 of larger dimensions.

FIGS. 5 and 6 are an exploded perspective view and a sectional view showing other examples of mounting a speaker unit using a switch box as a speaker box. In this example, a decorative board (plaster board) 14 is placed at a predetermined distance from the surface of the concrete wall 21, and a channel material 4
It is attached and fixed using 2 etc. In such a wall structure, the speaker unit is attached in the following manner.

First, prepare a standardized standard switch box 11,
When attaching and fixing the decorative board 41 to the concrete wall 21, it is fixed to the concrete wall 21 using screws 23.

A recess 43 is bored in the decorative board 41 as is done when installing a normal switch box. In this case, the connection work for the wiring hollow tube 24 is also performed at the same time.

When the construction work is almost completed, the mounting plate 12 on which the speaker 14 is mounted is pressed against the surface of the decorative board 41 and fixed to the switch box 11 using screws 44, as described above.

In this case, since the distance between the decorative board 41 and the concrete wall 21 is large, the screws 44 are long in accordance with the distance.

After the mounting plate 12 has been fixed, the speaker/car cover 16 is mounted using the mounting holes 17 and the protrusions 18 in the same manner as described above.

In this way, by using the switch box as a speaker box, as in the embodiment of the present invention described above, even in the case of a wall structure in which a decorative board is attached at a distance from a concrete wall, the speaker can be easily installed. The unit can be installed.

7 and 8 are exploded perspective views showing an example of a correction method when the switch box is installed diagonally in the speaker box mounting structure shown in FIGS. 5 and 6; FIG. 3 is a partially enlarged sectional view. That is, a through hole 51 having a larger diameter than the mounting screw 52 is formed in the mounting plate 12 of the speaker 14 that is mounted to the switch box 11, and a large diameter counterbore hole 51a is formed at the front end of the through hole 51. form.

A washer 53 having a diameter larger than the diameter of the through hole 51 and smaller than the counterbore hole 51a is prepared, and the washer 53 is assembled and the mounting plate 12 is mounted to the switch box 11 with the mounting screw 52. Even if the switch box 11 is tilted and fixed to the concrete wall 21, the mounting plate 12 can be installed with an appropriate shift due to the gap between the through hole 51 and the mounting screw 52 and the dimensional difference between the counterbore hole 51a and the washer 53. Therefore, the installation error of the switch box 11 can be adjusted.

(Effects of the Invention) As explained above, according to the present invention, by using a standardized switch box as a speaker box, the speaker unit can be easily and easily installed while being embedded in the wall surface. . Standard switch boxes are easy to obtain and are easy to handle, so they can be easily installed without causing any trouble during intermediate stages of construction work.
