Sounding music board

The invention relates to a sounding note board with the note lines or? -Contacts assigned between spaces and arranged under the surface of the notepad-

seemed to be the tone generators associated with the tone levels are connected, the generator assigned to a desired tone level by a Switching pin can be switched on, which can be inserted into a hole in the note board.

In sounding touch panels of this type, it has been known to act out by a single contact pin a predetermined perforation by a corresponding map melody characterized in that the contact pin of the given melody is inserted into the card perforated holes successively in the successive, accordingly. This has the disadvantage that a separate punch card must be used for each tone sequence. In addition, only a single note can be played at a time because only a single contact pin is available. This disadvantage can be eliminated if, according to the invention, the music board, especially provided with a metal coating, is provided along the note lines or spaces with through-holes for switch pins provided in any arrangement, preferably with the same pitch, which can be inserted resiliently into the through-holes and which represent the note image of the desired tone sequence. The design of the note board according to the invention makes it possible, using one and the same board, to produce different tone sequences as desired, and even to set polyphonic tone sequences.

The music board according to the invention is suitable for basic musical lessons because it allows to produce any sequence of notes in a simple way and at the same time, which is particularly important is to also represent the score, with which the

Pupils are given the opportunity not only to have the notes and, above all, the sequence of notes presented in front of them in terms of presentation, but also to receive an auditory impression at the same time.

The note board designed according to the invention enables as many notes as possible to be accommodated in a small space, because when playing the notes as opposed to making contact with a stick or with a single bolt no special accuracy is required, but only the individual notes need to be triggered in order to make the assigned note sound. It is also possible To produce three and multiple sounds by pressing the appropriate bolts at the same time. The note board designed according to the invention can be used for singing and meeting exercises without the aid of a Instrument in seconds, thirds, fourths, etc. and subsequent checking with the help of the sounding note board, simple rhythmic exercises (time signature) can be used, but dotted and show syncopated phythms vividly. Major and minor scales, triads and musical forms (Motif, repetition, sequence, shortening, cadence, variation and inversion) can be clearly displayed.

A further development of the invention is the resilient contact pin with a cover disk in the form of a note head Mistake. This makes it possible to depict the note values graphically.

The attachment of the contact pin can be done in a simple manner that below the note head an adhesive disk is provided for attaching the contact pin to the note board or that

To ensure good contact between the switch pins and their proper guidance In a further development of the invention, guide bushes are used in the bore of the music board.

In order to ensure good insulation, a further embodiment of the subject matter of the invention is provided the note board through an insulating layer, especially made of foam, at a distance from the contact rails held.

The invention is described below using an exemplary embodiment shown in the drawing explained in more detail. Show it,

The device according to the invention comprises a rear plate 5 and one covered by an insulating layer 7, e.g. made of foam therefrom held at a distance from the front panel 1, the front side of which is made of metal, so is conductive. The surface of the board 1 can be covered with white-gray cloth material 4 on which Staff lines are drawn in black and on the

all necessary peguisites (treble clef, time signatures, Accident marks, whole notes, half notes, quarter notes, note stems, flags or bars, rest marks, Barlines, etc.) stick. On the rear plate 5 run parallel to the No part lines, the intermediate lines (Gaps j and the auxiliary lines thin contact * - 6 rails made of metal. All Kontäktschieneri 6 of the rear Plate 5, which belong to the same tone level, are connected to each other and to those of the respective tone level associated tone generator C (Fig. 4) connected..For the system shown in the drawing only requires generators for 14 tone levels (tones), namely for (g2) (a2) h el dl el fl gl al hl c2 d2 f2 g2 a2. the Increments from: (g sharp2) (a sharp2) to dsl disT eist f sharp1 g sharp1 ai3i his1 cis2 dis2 eis2 fis2 gis2 ais2 and the humiliations from: (ges2) (as2) b ces1 des1 es1 fesi gesi as1 b1 ces2 des2 es2 fes2 ges2 as2 of the specific Notes are each generated with the aid of a rotary knob 8 by tuning the respective generator up or down brought to the desired pitch.

Through-holes 2 for switch pins 10 are introduced into panel 1 along the staff lines or the spaces in any arrangement, but preferably with the same pitch If a pressure is exerted in a through-hole 2, its free end comes to rest on the contact rail 6 opposite the through-hole 2, whereby a conductive connection is established between the panel 1 and the contact rail 6 and the tone generator assigned to this rail is made to sound, as _r 2 to 4 it can be seen from FIGS.. With a dimension of the Ta—, fei! Of 900 mm 1900 mm, about 1848 passage

Turn holes 2. So that the switch pins 10 have good guidance and contact is always guaranteed, are in the holes 2 of the Table 1 short guide bushes 3 inserted.

The resilient contact pin 10 is provided with a cover disk B i * in the form of a note head 9, which does not necessarily have to be made of metal and can be covered with adhesive cloth. The contact pin 10 can be screwed into the note head 9, so that the spring 11, which is arranged between the cover disk B and an adhesive disk 12 provided below the note head 9, can be re-tensioned at any time. which is used to attach the contact pin 10 to the note board 1. The adhesive disk 12 can be designed as a magnet. Genriß Fig. 4, the adhesive disk 12 is designed as a ring magnet and connected to the contact pin 10 by means of a transverse pin 13 which engages in a guide slot ausjesparten in the contact pin 10, so that a relative movement between tween the ring magnet and the contact pin is possible. Parts 10 to 14 are not visible to the viewer when the device is put into operation.

The tone generator can be operated with a battery. The respective tone can also be in vibrato sound.

If one musical note board is not sufficient, a second one can easily be used Panel can be connected, sneeze does not need a separate one Power source and not to contain a separate tone generator.
