Description

  The present invention relates to a sound generator that is operated by pressing a switch button.

  The conventional sound generator has an operation button and a speaker unit on the same surface, as shown by, for example, the name of the device and the onomatopoeia generator.

Reality 7-8613

  Since the operation button and the speaker portion are on the same surface, an area for arranging both of them is necessary, and in some cases, the size of the device has to be doubled.

  Position the operation button and the speaker unit on different surfaces, the operation button is provided on the front plate, the speaker unit is provided on the back plate, and the speaker unit is on the back, so the installation wall can also be used as an echo plate .

  The operation button is provided on the front panel, making it easy to turn on and off, and since there is no speaker on the front, there is less risk of the speaker getting wet even if water drops are applied. By installing it on the back plate, it can face the installation wall, and the sound emitted from the speaker part can be reflected on the installation wall to increase the sound. In the experimental results showing the difference, the installation wall material is P tile As a result of measuring from a position 1 meter away from the installation wall, the direct sound measured from the back direction showed 70.2 decibels, but measured from the front direction with the leg projections in contact with the installation wall. The reverberation sound shows 72.2 decibels, and as can be seen from the difference between the decibels of 2.0 decibels, the installation wall can sufficiently serve as a reverberation plate.

  FIG. 3 is a rear perspective view before installation of the fixture, and the sound generator 4 is installed inside the box body 2, and the installation structure is not limited, and may be installed on the back plate 6. The sound generation direction may be the back plate 6 and a plurality of lattice grooves 16 may be formed in a partial region of the back plate 6 located in the sound generation direction. 16 is rubbed out and leaked to the outside, and the lattice groove 16 may be formed at the center of the back plate 6 but preferably at the corner, and the lattice groove 16 is recessed to the corner. A plurality of parts can be provided on the same surface, and the volume of the generated sound is hardly changed by moving to the corner, and the holding part for installing the fixture 17 beside the lattice groove 16 18, a battery chamber 19 is provided at the bottom of the box 2, and the battery chamber 19 is attached to a chamber lid 20 provided at the bottom of the back plate 6. The finger lid 21 is provided at the center of the upper portion of the chamber lid 20 so that the chamber lid 20 can be easily opened / closed or detached. The detailed structure of the battery chamber 19 is omitted because it uses conventional technology. The positional relationship among the lattice grooves 16, the pressing portions 18 and the chamber lid 20 provided on the back plate 6 is preferably the above-mentioned state, but is not limited and may be replaced.

  In the fixture 17 attached to the back plate 6 of the box 2, only the fixture 17 in FIG. 3 is a front perspective view. The protrusion width is the same size as the protrusion of the leg protrusion 8 or a size including play, the hem weir portion 22 is provided as a pair of surface objects, and the basic shape is an L shape bent at a right angle inside The shape is formed, and the L-shape makes it possible to follow the lower end and the inner surface of the leg protrusion 8 located at the lower part, and the guide is appropriately raised inward and upward from the top of the L-shape. It is desirable to extend the region 26, and in the upper region of the fixture 17, one corner region is removed to form a window region 23, and the other corner region moves in parallel to the front via the stepped portion 24. By extending the extended side area 25 and making the protruding width of the stepped portion 24 the same as the protruding width of the hem weir 22, The area 25 can run along the back plate 6, and the back plate 6 and the area 25 are aligned with each other so that the sliding groove 27 provided in the cut shape in the area 25 is slid in the front direction of the presser portion 18. Since the window area 23 is provided in a positional relationship overlapping with the area of the grating groove 16, it prevents the sound that is scraped off from the grating groove 16 from being blocked. The area is defined as a holding area 28, and the front surface of the raising area 28 may be flat, but it is desirable to provide a reinforcing plate 29 that is appropriately projected in a plate shape. The shape of the reinforcing plate 29 is not limited, and is a straight plate. However, an inverted T-shape is desirable because it can reinforce the vertical direction at the same time, and it is desirable to open a mounting hole 30 for fixing by inserting a screw nail, a nail or the like in the brazing area 28. .

  FIG. 4 is a rear perspective view of the mounting state of the fixture. When the box 2 of the apparatus 1 is placed on the floor and the table, there is no need to install the tool, but it is shown in FIG. When installing on the installation wall 7, a dedicated tool is required. If the installation method on the installation wall 7 is described, the through holes 10 are opened in the upper and left two leg protrusions 8. It is desirable to pass a string having an appropriate thickness and strength to the loop, and the threaded string is preferably a loop. The looped string is hooked on a hook-shaped protrusion protruding from the installation wall 7 and suspended to install the device 1. There is a problem that the suspension by the string is shaken or tilted. In the installation method using the fixture 17 as a method for solving the above-described problem, the sliding groove 27 provided on the upper portion of the fixture 17 is provided. Is slid into the front of the presser portion 18 and pressed down, and the lower corner areas of the fixture 17 are Since the letter-shaped hem weir 22 is in contact with the leg protrusion 8, the lateral displacement is suppressed, and the installation structure of the fixture 17 itself is attached by attaching an adhesive to the back of the warming area 28. It may be fixed, and the sticking method is not limited. Adhesion with adhesive glue, sticking with adhesive glue, glue may be used, and double-sided adhesive tape may be used. A nail may be inserted and fixed in place, or it may be installed using both sticking and fixed in place. If the fixture 17 is firmly fixed, the installation state of the apparatus 1 is also good. Since it is stable and only fits by its own weight, the device 1 can be easily attached and detached.

  In the installation structure using the fixture 17, the region of the fixture 17 that overlaps with the lattice groove 16 is removed as a window region 23, and by having the window region 23, the progress of the sound that rubs out of the lattice groove 16 is blocked. In addition, the moat area 28 forms a gap 9 in addition to the role of being installed on the installation wall 7, so that the sound echo effect can be maintained.

  FIG. 5 is a right side view of the partial peeling of the reverberation measurement state, in which the measuring instrument 31 is installed at a position away from the surface of the installation wall 7 by an arbitrary distance L, and the length of the distance L is Although it is not limited, it is set to 1 meter as an arbitrary numerical value, and the installation wall 7 is shown as being vertical, but it may be horizontal. In the reverberation measurement of this figure, the front plate 5 of the box 2 of the apparatus 1 is measured. It is desirable to have a gap 9 between the back plate 6 of the box 2 and the installation wall 7, and to adjust the gap 9 as the gap width S. The change of the sound that the sound generated from the sound generation unit 4 reverberates on the installation wall 7 due to the adjustment of the gap width S is measured, and the original volume emitted from the sound generation unit 4 can be adjusted, but is arbitrarily constant. The leg protrusion 8 is removed from the necessity of measuring the state in which the gap width S where the back plate 6 is in contact with the installation wall 7 is zero. Except for are shown.

  FIG. 6 is a left side view of the direct sound measurement state partial peeling, and the numerical value of the distance L is set to 1 meter of the same size, and in the direct sound measurement of FIG. The gap width S is 0 because the entrance / exit 3 that slightly protrudes in front of the apparatus 1 is in contact with the installation wall 7, and the sound generated from the sound generator 4 is not measured. The measuring instrument 31 is located in the traveling direction.

  FIG. 7 is a measurement result table in which the gap width is adjusted. The reverberation sound is measured with the structure shown in FIG. 5, and the measured sound volume changes due to the adjustment of the gap width S, and the gap width S is too wide. However, the volume is reduced even if it is too narrow, and the maximum value is that the gap width S is 4 mm. Therefore, the length of the leg protrusion 8 that defines the width of the gap 9 is best 4 mm.

  FIG. 8 is a measurement result table of the volume change due to the difference in the installation wall material, the reverberation sound is the measurement from the front direction shown in FIG. 5, and the direct sound is the measurement from the back direction shown in FIG. In the steel and P tiles, which are highly reverberant, the reverberant sound has a larger value, and in the napped mat, which is a sound absorbing material, the sound has a greater value than the low reverberant material. As long as the sound absorbing material is not used as the installation wall 7, the installation wall 7 can enhance the echo effect.

  Although not shown, if other measurement results are described, the measurement direction of the apparatus 1 is the reverse of 180 degrees in FIG. 6 with respect to FIG. Shows a value lower than the reverberation sound and direct sound because it is 66.6 decibels, and the measurement distance L is set to 1 in a state where the installation wall 7 is 1 meter away from the installation wall 7 and the reverberation effect of the installation wall 7 is eliminated. If we describe the result of the measurement with a meter (2 meters from the installation wall 7), the measured value from the front direction is 63.6 decibels, and the measured value from the back direction which is a direct sound is 66.4 decibels. there were.

  The purpose of the present invention is to generate an artificial sound of the drainage sound of a flush toilet and make it difficult to hear the falling sound or the discharged sound of urine etc. In addition to the generation of comfort sounds such as singing and waving, it can also be applied to a ringing tone generator.
