Although they are connected by screws not shown in the figure, the screws cannot be connected easily because the screws are connected from the inside of each of the boxes 1 and 5.

An object of the present invention is to provide a music apparatus in which each box and diaphragm can be easily attached in view of the above-mentioned conventional problems.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention has a speaker box facing each other at a predetermined interval, a vibration plate to which a vibration device is attached and which is interposed between the speaker boxes, a speaker, and A music device having a drive control device for the vibration device and a control box interposed between the rear parts of the speaker boxes, wherein the box and the vibration plate are connected by a connection member, wherein the connection member is the A first member extending along an inner side surface of each speaker box and attached to the side surface.
A connecting plate, a second connecting plate extending from the rear end of each of the first connecting plates along the peripheral side surface of the control box and attached to the peripheral side surface, and installed between the first connecting plates. And a support rod for connecting and supporting the vibration plate.

(Operation) According to the present invention, each speaker box is attached to the first connecting plate of the connecting member, the control box is attached to the second connecting plate, and the vibrating plate is attached to the supporting rod. As a result, the music device is assembled.

(Embodiment) FIGS. 1 and 4 to 6 show an embodiment of the present invention, in which 10 is a speaker box facing each other at a predetermined interval, 20 is a diaphragm, 30 is a control box, and 40. Is a connecting member for connecting the respective boxes 10 and 30 and the vibration plate 20.

Each of the speaker boxes 10 is formed in an elongated shape in the front and rear, accommodates a speaker (not shown), and has a speaker grill 11 on the rear side.
Is installed. The diaphragm 20 is formed in a rectangular shape,
As shown in the figure, the vibrating device 21 is attached by screws 22 to the back surface of each corner side. The vibrating device 21 is well known, and its structure is, as shown in FIG. 6, mounted with a flat annular permanent magnet 212 and a sponge 213 in a case 211, and an exciting magnet facing the permanent magnet 212 at a predetermined interval. The coil 214 is internally provided. The leaf spring 21 is provided on the winding frame 215 of the exciting coil 214.
6 connects to allow the winding frame 215 to vibrate, and a lead wire 217 is connected to the exciting coil 214, and a current based on a music signal or the like is applied to the exciting coil 214. In addition, a hook hole 218 penetrating toward the sponge 213 is formed in the lower case 211a of the case 211, and a hook metal fitting 48 of the connecting member 40 described later is inserted into the hook hole 218. There is. The control box 30 is horizontally long and has a drive control device (not shown) for controlling the drive of each speaker and the vibration device 21.

The connecting member 40 includes a pair of first connecting plates 41, a pair of second connecting plates 42, and two supporting bars facing each other as shown in FIG.
It consists of 43. Each first connecting plate 41 extends along the inner plate 12 of each speaker box 10 and has a plurality of screw insertion holes 44. The inner plate 12 is provided with a plurality of screw holes 13 facing the screw insertion holes 44,
The speaker box 10 is attached to the first connecting plate 41 by inserting the screws 45 into the screw insertion holes 44 and fastening the screws 45 into the screw attachment holes 13.

The second connecting plate 42 extends from the rear end of the first connecting plate 41 to the longitudinal side plate 31 and the back plate 32 of the control box 30.
A screw insertion hole 46 is formed on the rear end side. Further, a screw hole (not shown) facing the screw insertion hole 46 is provided in the back plate 32, and the control box 30 is secured by inserting a screw 47 into the screw insertion hole 46 and tightening the screw. It is connected to the second connecting plate 42.

The support rods 43 are provided in front of and behind the respective first connecting plates 41, and are each slightly curved downward. Further, on both sides of the support rod 43 on the front side, hooking metal fittings 48 facing the hooking holes 218 of the vibration device 21 are provided upright.
The hook 48 is a vertical piece 48 extending vertically from the support rod 43.
1 and a hooking piece extending diagonally forward from the upper end of the vertical piece 481
482, the hooking piece 482 is inserted into the hooking hole 218 and hooked on the lower case 221a to attach the diaphragm 20 to the supporting rod.
It is placed on 43.

When assembling the music apparatus according to this embodiment, first, the control box 30 is positioned between the second connecting plates 42 of the connecting member 40, and the control box 30 is screwed into the control box 30.
30 is attached to the second connecting plate 42. Next, the screw holes 13 of the speaker boxes 10 and the screw insertion holes 44 of the first connecting plate 41 are opposed to each other, and the speaker boxes 10 are attached to the first connecting plates 41 with screws 45. And each hook metal fitting 48
The hooking piece 482 is inserted into the hooking hole 218 of the vibration device 21, and the diaphragm 20 is rotated about the hooking hole 218 as a fulcrum to rotate the diaphragm 2
0 is placed on each support rod 43. This completes the assembly of the music device.

As described above, since the speaker box 10, the diaphragm 20, and the control box 30 are connected by the single connecting member 40, the assembling work of the music apparatus is very simple.

Further, each support rod 43 is curved slightly downward, and a gap is formed between the axial center of each support rod 43 and the back surface of the diaphragm 20. Therefore, the center of the support rod 43 can be gripped, and the support rod 43 can be used as a handle for transportation.

As described above, according to the present invention, each speaker box is attached to the first connecting plate, the control box is attached to the second connecting plate, and the vibrating plate is attached to the supporting rod.
There is an advantage that the music apparatus can be assembled with one connecting member, and the assembling work is simplified.
