FR2880978A1 - Whistle for imitating bird song, has spacer folded into two parts along axis constituted by its diameter for providing rigidity to whistle after pressing and for assembling spacer with whistle body and membrane - Google Patents

Abstract

The whistle has a membrane (3) and a whistle body (1) made of flexible material for permitting the whistle to be plated against palate without letting air flow between the palate and the body. A spacer (2) is folded into two parts along an axis constituted by a diameter of the spacer for providing rigidity to the whistle after pressing and for assembling the spacer with the body and membrane.

Description

2880978 -l-

  The present invention relates to a device which, being placed in the mouth, produces by expiration a whistling sound characteristics of which are controllable by the user.

  Whistling devices are generally becoming more and more cumbersome as they are perfected and offer qualities of acoustic variation.

  In addition, the alteration of the pitch of notes (treble / bass) for traditional piping devices requires manual intervention by plugging holes (flutes, happeaux) or by sliding pistons (paper clips) to reduce the volume of resonance .

  Finally, only three organs (lungs-diaphragm, throat and tongue) produce sound effects (fluctuations of intensity, saccades, gargles and others).

  The device according to the invention overcomes these disadvantages. Being small, it is applied on the tongue without even having an external part and does not enlarge the mouth. With the help of the tongue and exhaling air, the whistle is registered at the front of the palate (behind the teeth). The ducted air stream passes only between the tongue and the membrane. The latter vibrates and produces whistling.

  Being totally internal, the pitch of the notes is given by the oral volume depending on the throat and the tongue. There is no use of hands.

  In addition to other techniques, the lips can be used in the full extent of their deformation and flexibility to add effects to harmonious and varied modulations.

  The device according to the invention is particularly intended for the imitation of birdsong.

  According to particular embodiments; - The outline of the whistle body can be smooth, sawtooth or crenellated to ensure a better whistle on the palate.

  the washer, allowing the assembly and rigidity of the device, can be serrated to ensure a better holding of the membrane.

  the washer may also be of different diameters and of different shapes giving different ranges of sound. The accompanying drawings illustrate the language invention).

  Figure 5 shows the whistle (face sticking to the palate). Figure 6 shows the whistle in its environment.

  Referring to these drawings, the device comprises the whistle body (1) of flexible material which allows the whistle to be pressed against the palate without allowing air to pass between them.

  The side of the whistle body (1) where the membrane (3) is located will be placed on the tongue.

  A washer (2) folded in two (along an axis given by its diameter) makes it possible, after pressing, to obtain the rigidity of the device and the assembly with the two other parts which are the body of the whistle (1) and the membrane (3 ).

  A membrane (3) in the form of a ribbon can be envisaged for industrial application which is only cut after assembly of the devices along the chain.
