Abstract
The invention relates to a whistling device (1) comprising a rigid thin plate (2) folded to form two segments having an acute angle between them. Each of the segments has an aperture (3) located substantially opposite the other aperture. The whistling device is adapted to be placed in the mouth and produce a shrill sound when air is blown therethrough.
Description
- The present invention relates to a device for producing a shrill clear sound, in particular to a device adapted to be placed in the mouth and produce the shrill sound by blowing air, through the device.
- It is well known to whistle and produce a musical sound, without the use of the vocal cords, by blowing air through the pursed lips. The sound obtained is shrill and clear. However, the intensity of the sound thus obtained is limited and a great effort is required for producing the sound. It is also well known to whistle by utilizing a whistle, a small wind instrument in which sound is produced by the forcible passage of breath through a slit in a short pipe or tube. The sound thus obtained can be of higher intensity than the sound obtained by blowing air through the pursed lips without using any device. However, such sound usually has a different tone than the tone produced by whistling without the use of known whistles.
- It is the object of the present invention to provide a device which enables producing a shrill clear sound, imitating the tone of the sound produced by whistling without using any external device. It is a further object of the invention to provide a device which produces a sound of a much higher intensity than the intensity of the sound obtained by forcing air through the lips without the device of the invention.
The use of the device is simple and very little effort has to be devoted in order to produce the high intensity sound, as compared with producing the sound by blowing air through pursed lips. Therefore, the device of the invention can easily be used by any unskilled person including children and women, and not only by those skilled in whistling by forcing air through pursed lips. The device of the invention is small and simple and fits easily into the mouth. - In accordance with the invention there is provided a device for producing a shrill sound comprising a rigid thin plate folded to form two segments having an acute angle between them, wherein each segment has an aperture located substantially opposite the other aperture, adapted to be placed in the mouth and produce the shrill sound when air is blown therethrough.
The device of the invention can be made of any rigid thin material such as plastic or metal. The acute angle between the two segments of the device is such that the device can easily fit into the mouth. Thus, the acute angle can range between 5 degrees and 45 degrees. Preferably the acute angle ranges between 10 to 30 degrees.
The aperture can be of any shape, such as round or rectangle. Preferably the aperture is a round hole having a diameter ranging between 1.5 to 2.5mm. For an easy insertion of the device into the mouth, it is preferred that a handle extends from one of the segments of the device. The handle can be of any desired shape and since the device is quite small in its dimensions, the handle can serve as means for attaching the whistling device to other handy devices needed by the user. - The invention is illustrated by way of example with reference to the accompanying drawings in which:-
- Figure 1 is a perspective view of a device according to the invention.
- Figure 2 is a top view of the device shown in figure 1.
- Figure 3 is a top view of the plate used to produce the device shown in figure 1.
- Figure 4 is a perspective view of another embodiment of the invention.
- Figure 5 is a perspective view of yet another embodiment of the invention.
- Figure 6 is a perspective view of another embodiment of a device according to the invention.
- Figure 7 is a perspective view of the device shown in figures 1 and 2 when placed in the mouth of the whistler for producing a shrill sound.
- Figure 8 is another perspective view of the device shown in figures 1 and 2 when placed in the mouth of the whistler.
- Device 1 shown in figures 1 and 2 is made of a
rigid round plate 2, shown in figure 3, having tworound holes 3 and ahandle 4 which form an integral part of the plate. Whenplate 2 is folded alongline 5 to an angle of about 20 degrees, device 1 is produced.Handle 4 shown in figure 1 has a hole 6, centrally located therein. Hole 6 can be used in order to attach device 1 to other articles such as a chain (not shown in figure) holding keys, tokens or the like. In order to produce the shrill sound utilizing device 1, device 1 is placed in the mouth, as illustrated in figures 7 and 8, so that itsstraight edge 7 is pressed against the tongue 9 and itsround edges 8 are pressed against the lips, one round edge against the bottom lip and the other round edge against the upper lip. Such positioning of the device in the mouth forms a substantially sealedcavity 10 between the tongue 9, thelower palate 12 and the lower side of device 1. Cavity 11 is formed between the roof of the mouth (i.e. the upper palate) 13, the upper side of device 1, and the tongue 9. Cavity 11 is connected to the windpipe (not shown in figures) and has but one small opening i.e.hole 3 at the upper side of device 1. When air is forced from the lungs while device 1 is placed in the mouth as described above, the air passes from the lungs via the windpipe and the throat to cavity 11 where its only outlet ishole 3. Some of the air coming out ofhole 3 at the upper side of device 1 is forced intohole 3 of the lower side of device 1, and oscilates incavity 10. The flow of air coming out ofhole 3 at the lower side of device 1 as shown in figures 7 and 8 by arrows, makes the shrill sound. -
Devices rigid rectangle plates 32, each having tworound holes 33.Device 30 comprises two equal segments whiledevice 31 has two unequal segments. Thelong segment 34 ofdevice 31 serves as a handle.Devices -
Device 20 shown in figure 6 represents another embodiment of the invention.Device 20 has all the essential features of device 1, i.e. a plate of anoval shape 22 folded along itsmain axis 25 having twoholes 23, one on each side of the folded plate.Device 20 also has abox 24, sealingly attached to the outer side of one of the segments ofplate 22. In order to produce a shrill sound utilizing thedevice 20,device 20 is placed in the mouth so that thebox 24 is directed towards the bottom of the mouth and the tongue and lips are placed as with device 1 described above. Whendevice 20 is used for whistling it is not essential to form a sealed cavity between the tongue, the lower palate and the lower side of the device, becausebox 24 serves as a sound box. The dimensions ofbox 24 determines the tone of the sound produced by blowing air throughdevice 20.
Device 20 can also be used for whistling by forcing air through theopen hole 23 while the whole device or part thereof is placed out of the mouth.
