Description

[Detailed explanation of the invention] (Field of industrial application) This invention generates vibration force in response to a low-frequency audio signal, and uses this vibration force to vibrate a diaphragm that is a part of the floorboard. , relates to a floor vibrating panel.

(Prior Art) To listen to music, speakers or headphones are commonly used. It is common to listen to music using speakers or headphones that rely solely on the sense of hearing, and it can serve its purpose well. It is still not perfect, and this requirement becomes even greater when the volume is lowered.

Therefore, a device was devised that extracts a low-frequency signal of about 150 Hz or less from the output component of an amplifier, applies it to a vibration unit that converts it into mechanical vibration, and uses this vibration unit to vibrate an object placed on the human body, such as a chair. Patent applications or utility model registration applications have been filed for various parts. However, even with such a device, there were still unavoidable problems. In other words, the question is whether multiple people can experience vibrations at the same time, even while walking. Therefore, it was devised to vibrate the entire floor of the room using an acoustic signal, and a patent application has already been filed (see Japanese Patent Laid-Open No. 122097/1983).

(Purpose of the invention) Although all conceivable technical problems were solved by the invention of the above patent application, when it came to the stage of actually manufacturing it, more detailed problems arose that needed to be solved. For example, when a plurality of diaphragms are bonded together and spread throughout a room, abnormal noises may occur due to friction at the edges of adjacent diaphragms. Therefore, in this invention, the main purpose is to suppress the generation of this abnormal noise,
It is an object of the present invention to provide a vibrating panel for floors that solves these problems as well as other problems.

(Structure of the invention) In order to achieve the above object, the present invention has a structure of a floor vibrating panel that has a fixed shape, and when a plurality of panels are lined up and joined together, one unit of panel that forms a floor plate is at least a diaphragm. and a leg part that lifts the diaphragm above the floor surface, and the length of the leg part is such that when the vibration unit is attached to the diaphragm, the lower surface of the vibration unit does not come into contact with the floor surface, at least a portion of the panel that is indistinguishable from adjacent panels;
A cushioning material such as a rubber plate is attached.

(Function) With this configuration, when the panels are joined, the friction caused by rubbing between adjacent panels is attenuated by the cushioning material (or does not occur in the first place), and no abnormal noise is generated. . In addition, there are other effects such as reducing the overall height (thickness) or not transmitting vibrations to other rooms below the floor.
effect can be obtained.

(Embodiment) Next, an embodiment of the present invention will be explained with reference to the drawings. In Fig. 1, 1 is a panel, and a plurality of panels are laid on a concrete floor of a building to form a floorboard. It is one unit of something.
As is clear from FIG. 2 showing the cross section and FIG. 3 showing the back surface (floor surface), this panel 1 has square timbers 3, 4, and
are pasted to form a framework.

The lengths of the square members 3 and 4 are shorter than the width of the diaphragm 2, and therefore, in the spaces created at the corners of the diaphragm 2, there are legs that lift the diaphragm 2 above the floor (not shown). The section 6 is provided with its head slightly retracted and its lower part protruded slightly. The head portions of the legs 6 are slightly retracted in order to place a connecting plate 15, which will be described later, and the lower portions are slightly protruded to raise the entire panel 1 above the floor.

As shown in Figures 2 and 4, the diaphragm 2 is made of a relatively thin plate material (veneer board), and a plurality of vibration units 7 (see Figure 3) are installed at regular intervals on the back side of the diaphragm 2. It is being The vibration unit 7 has a permanent magnet in a fixed part and a coil in a movable part close to the permanent magnet, and the magnetic force of the coil that emits a magnetic force changed by the sound current and the magnetic force of the permanent magnet are combined. This structure generates vibrations due to the magnetic interference between the dampers and the spring action of the damper.

As shown in FIGS. 3 and 4, the structure for attaching the vibration unit 7 to the diaphragm 2 includes holes 10 and 1 in the plate materials 8 and 9 where the vibration unit 7 is attached.
1 is provided and buried in the holes 10 and 11.
This increases the transmission efficiency to the diaphragm 2 and prevents the overall height from increasing due to the attachment of the oscillating unit 7. Note that instead of doing this, it is also possible to provide only a mounting seat for the vibration unit 7 without providing the plates 8 and 9 at the bottom of the diaphragm 2, and to attach this mounting seat to the back surface of the diaphragm 2. However, in this case, the load capacity value will decrease.

Next, a structure for laying a plurality of panels 1 configured in this way on a floorboard will be explained. When a plurality of panels 1 are joined together and an audio current is passed through the vibration unit 7, the part of the diaphragm 2 where the vibration unit 7 is attached may be in an opposite phase state, and therefore the adjacent panel 1 may rub against each other, causing abnormal noise. So leg 6
A cushioning material 12 such as a rubber plate is attached to the outer periphery (see FIGS. 6 and 7). If this is done, a gap equal to the thickness of two cushioning materials 12 will be created at the outer periphery of the panel 1, but since a carpet is laid on the top surface of the panel 1, there is no practical problem. Note that the cushioning material 12 may be attached to a portion other than the leg portions 6, that is, to the entire outer periphery of the panel 1.

As shown in FIG. 5, male and female connectors 14 and 15 are protruded from both sides of the panel 1 by means of cords 13, so that adjacent panels 1 can be connected to each other. In this way, the vibration units 7 of each panel 1 are connected and simultaneously receive output signals from an amplifier (not shown). The vibration units 7 are connected to each other as shown in FIG. In FIG. 6, the reference numeral 16 indicates a back plate. The cord 14 is appropriately stored in the lower part of the panel 1.

What is shown in FIGS. 8 to 10 is the connection plate 17.
The hole 18 in Fig. 8 is for the corner, the one in Fig. 9 is for connecting two panels 1, and the hole 18 in Fig. 10 is for connecting four panels 1. It is for connection. These are appropriately selected and used, and a plurality of panels 1 are joined together as shown in FIG. 11. The thickness of the connecting plate 17 is made equal to the amount by which the head of the leg part 6 is slightly retracted. This will result in an overall flat surface.

(Effects of the Invention) Since the present invention uses the structure described above to join a plurality of panels, no abnormal noise is generated between adjacent panels. Furthermore, since the structure is simple and the overall thickness can be made small, installation on the floor of a building is easy, and a floor vibration panel with high practical value can be obtained.
