Description

[Detailed explanation of the idea] This invention relates to improvements in implantable signaling devices.

Recessed signaling devices are traditionally well known;
For example, there is something like the one shown in Figure 1. In this conventional example, exposed portion _A1 and switch box D
Part A to be embedded in A container with approximately the same size as ₂
At A ₀ , the exposed portion was configured to cover the cutout F of the wall surface E with the plate frame B and the decorative plate C. G is a mounting bracket. Therefore, the exposed and embedded cross-sectional areas of container A are the same, and the size of the sound generating means is 1
The drawback was that it was too large to fit into a personal switch box. However, in the market, switchboxes for 1 unit are easier to obtain than switchboxes for 2 units, and the price is lower, and the size of the cut hole in the wall is smaller, making it easier to obtain 1 unit switchboxes during construction. It is easier to work on a switch box.

The present invention aims to improve the above-mentioned drawbacks, and provides an empty space for mounting an electroacoustic transducer and a printed board on which electronic components constituting an electronic circuit for driving the electroacoustic transducer are mounted. and a downward protrusion for receiving a voltage drop transformer, the positions of the electroacoustic transducer and the voltage drop transformer are offset in a plane so that they do not overlap, and the height of the exposed portion is Reduce the dimensions,
Moreover, it provides an embedded signal device that can be attached to a small switchbox.

A detailed explanation will be given below based on examples.

In FIGS. 3 to 5, reference numeral 1 denotes an exposed portion, and a cavity 4 is formed by the body 2 and the upper flat plate 5 of the base 3. The base 3 has a downward protrusion 7 which receives a voltage drop transformer 6 and has wire connection means 8, 8, . . . mounted thereon. Note that the body 2 may be composed of a body frame 9 and a decorative plate 10 that covers a part of the body frame 9. The body frame 9 is provided with holes 12 for mounting an electroacoustic transducer 11, such as a speaker, and holes 14, 14 through which screws 13 for attaching the device to a switch box pass. 9a is a hole that exposes the test push button 9b. A printed board 17 on which electronic components 16, 16 constituting an electronic circuit 15 for driving the electroacoustic transducer 11 are mounted has a hole 18 through which the back surface 11b of the electroacoustic transducer 11 passes, and a hole 18 through which the back surface 11b of the electroacoustic transducer 11 passes.
It has a notch 20 for attaching a slide volume 19 for adjusting the sound volume generated by 1, and holes 21, 21 through which screws 13 pass.

The base 3 has a flat top surface and a voltage drop transformer 6
In addition to the downward protruding part 7 which is a receiving part, there are holes 5a, 5a through which the screws 13 pass, holes 5c through which the screws 25, 25, . . ., which connect the body 2 and the base 3 pass,
5c..., engaging pieces 5d, 5 that engage with the body 2
d.

Thus, the electroacoustic converting means 11 is attached to the body frame 9.
It is installed through the hole 12 provided in the body frame 9 and fixed to the body frame 9 with screws 29, 29. Next, printed board 1
A vacant room 5 consisting of a body frame 9 and a base 3.
Attach to. At this time, a hole 18 is formed at a position such that the back surface 11b of the electroacoustic transducer 11 passes through the hole 18 in the center of the printed board 17. As shown in FIG. 3, the center line α of the electroacoustic transducer 11 and the center line β of the voltage drop transformer 6 are offset in a plane and are arranged in a positional relationship such that they do not come into contact with each other. Then, the body 2 and the base 3 are connected using screws 25, 25. When installing the device by embedding it, the screw 13 is installed through the screw through hole 14 in a switch box installed deep into a hole cut in the wall surface. If the device is equipped with a decorative plate, it is attached with screws 13 and then the decorative plate 10 is installed so as to cover the screw through holes 14, 14 and the electroacoustic transducer 11.

As described above, according to the invention of the present application, there is an exposed portion provided with a cavity for mounting an electroacoustic transducer and a printed board on which electronic components constituting an electronic circuit for driving the electroacoustic transducer are mounted, and a voltage drop A container is formed having a downwardly protruding portion that receives the transformer and is equipped with a wire connecting means, and when this container is attached to a switchbox embedded in a wall surface, the downwardly protruding portion is embedded in the switchbox and the above-mentioned In the implantable signal device in which the exposed portion covers the wall cutout, the positions of the electroacoustic transducer 11 and the voltage drop transformer 6 are shifted in plane so that they do not overlap. Therefore, the electroacoustic transducer and the voltage drop transformer, which are the parts that make up the signal equipment and have a large internal height dimension, are placed flatly at the position L ₀ , which has the large height dimension of the equipment. Since they are arranged offset and the height dimensions overlap, it is possible to reduce the exposed dimension _L1 of the instrument, and the only part that enters the switchbox is the downward protrusion 7 of the base, making it small. It can also be attached to a switch box (for example, a single switch box).
