Description

Combined musical instrument, consisting of a

Accordion and an electronic organ The invention relates on a combined trusical instrument, which consists of a keyboard equipped with a conventional accordion and an electronic one that can be activated with these buttons Organ consists, the organ with the keys of the accordion via microswitches and an electrical circuit can be actuated.

They are combined musical instruments, consisting of a harmonica and an electronic organ known in which the keys of the accordion part coupled with the corresponding inputs of the organ via electrical switching contacts are. With these instruiaents each time the assigned Button flexures actuated, which close a corresponding circuit and thus activate the electronic organ part. An arrangement of this type is for example from DE-PA 20 20 017 known.

Also known from U.S. Pat. No. 2,983,178 and U.S. Pat. No. 3,084,584 Arrangements of musical instruments known, in which especially the electric Switch consist of a package of leaf springs that are in their rest position without mutual Contact are aligned essentially parallel and when depressing each assigned button close a circuit via pins, which the electronic Organ part activated.

In these known arrangements in which an electrical contact is made using flexible links or leaf spring assemblies, but can only be chromatic Harmonica (accordions), that is, harmonicas, in which the operation of the bellows the same tone is produced both when pulling and when pushing.

Harmonicas that are released when the bellows are pulled or pushed Generating different tones, i.e. diatonic harmonicas, can be used in the so far known way cannot be converted into combined musical instruments.

The object of the invention is to provide a combined musical instrument of the to create the aforementioned type, which makes it possible to create a diatonic harmonica for the combination with an electric organ to equip so that both the same tones are obtained when pulling as well as when pushing the bellows will.

This object is achieved according to the invention by a combined musical instrument, Consists of a harmonica with keys and one with these keys activatable electronic organ, which with the keys of the accordion via microswitches and an electrical circuit can be actuated, achieved in that the Harmonica is at least one diatonic harmonica, and that to convert the different generated when compressing or pulling apart the air bellows Tones of the harmonica in any keys at least one diaton converter (diaton converter) is provided on the harmonica.

For the first time, this opens up the possibility of a combined Musical instrument, consisting of an organ and a diatonic harmonica, too create. By installing a diatonic converter in a conventional diatonic Harmonica can activate an electronic organ in such a way that the when pressed together or pulling apart the air bellows differently generated tones of the diatonic Harmonica can also be triggered synchronously on the electric organ. The im further shown simple structure of the converter and the other actuating elements it is possible to retrofit existing diatonic harmonicas and at any time using suitable connection systems as a combined musical instrument or to be used as a single device in its original state. It can therefore for the first time be a electronic organ with a diatonic drawbar monika combined without changing the shape of the original instrument with timbres, rhythm and automatic bass of the electronic organ optionally can be fully used.

It is particularly advantageous that a mechanical one, if desired or automatic sound switching can be provided.

For purely mechanical sound switching, according to the invention, preferably mechanical tone switching buttons can be arranged on the left bass side of the harmonica. A movable actuating plate is used for joint actuation of the switching keys Arranged above the buttons in such a way that they are for example by means of pressure The ball of the hand can be operated in such a way that all microswitches are pressed at the same time and the sound switching goes smoothly. Preferably the Guide the connecting line between the keyboard on the right side of the diatonic Harmonica and the mechanical switching device via the actuating plate arranged through the bellows interior. A particular advantage is achieved when between the actuator plate and tone switch button or bearing block made of elastic material molded plugs or bands are arranged. This creates a distance and pressure compensation between the interacting parts achieved.

For automatic (electronic) sound switching is in the circuit one cooperating with a light emitting diode and a phototransistor and with air Light barrier that can be actuated from the bellows of the harmonica is provided. Depending on, whether the bellows is compressed or pulled apart, depending on whether overpressure or underpressure occurs, the light barrier moves between the photoelectric elements or withdraws so that a rest position or activation of a circuit is achieved.

According to a further development of the inventive concept, the light barrier is a piston, or an element connected to the piston, for example a piston rod, wherein the piston is slidably arranged in a cylinder. The cylinder is in turn connected to the bellows space via a hose. When actuated of the bellows is.

consequently the resulting overpressure or underpressure via the hose continue into the cylinder, whereby the piston up to a limiting element (bracket) slides forward or moves up to the stop on a limiting element (limiting pin) withdraws.

In order to avoid premature wear, the piston is advantageously made of known wear-resistant materials such as sustamide, whereby good sliding properties are also obtained at the same time.

For example, when a sound button is pressed in the state of the train of the bellows (negative pressure) via IC modules and a circuit via contacts in such a way that the tone «ft is activated from it. This means that in the electronic organ triggered the selected tone n ft. On the other hand, it is the same Key in the state of pressing the air bellows (overpressure) via the automatic switchover On the printed circuit board the IC module is activated so that contacts form a circuit close, which triggers the selected note e "in the electronic organ and synchronously reproduces with the diatonic harmonica.

In the case of overpressure, which is in the range of a few millimeters moved, the control piston arranged on the circuit board will snap forward and thereby interrupt the light beam of the light emitting diode, which is directed to the phototransistor. aby activates the IC driver stage assigned to the individual tone keys and the necessary switching, which is necessary to close the circuit for the tone "e" necessary is made.

Then it becomes the same, for example if the actuation remains the same If a vacuum is generated by pulling the sound button, this pulls the piston back and the light beam to the phototransistor is released again. The IC driver stage now switches on the IC components in the opposite direction, whereby the original Starting position is restored.

Appropriately used for carrying out the invention The printed circuit board is therefore designed in such a way that the IC components can be used when the prevailing Negative pressure remain inactive as a result of pulling the air bellows, i.e. in the initial state (Idle state), but activated when pressure is present.

According to a further development of the inventive concept, between the circuit board of the Diaton converter and the air flaps connected to the sound buttons Contact buttons (microswitches) that can be operated via the air flaps are provided. Between the back of the air flaps and the circuit board or

the microswitches provided thereon are always a multiple angled spring clip arranged. This spring clip that works in an advantageous manner a spring steel bracket made of spring steel wire or spring steel tape is with one end attached to the circuit board and extends with its other end to the rear of the air flap. The spring steel clip grips around the microswitch partially in such a way that through the middle part of the spring steel bracket the microswitch can be activated.

The inventive arrangement of microswitches and the design of the spring steel bracket as power transmission elements allow production-related Tolerances resulting from the manufacture of the air flap for the sound generation Installation of the sound converter result in compensation. Through low to press the tone key is the force via a key lever, a key lever joint with return spring, transfer a tone key lever and the air key to the spring clamp. This activates the contact button (microswitch), which by the spring pressure that circuit includes, which is necessary for the electronic sound generation to the for this Key to generate associated tone.

This automatic switching, which the function of the Diaton switch characterizing, also enables the different tones of the diatonic harmonica (Bb, Eb, A-C, F, Bb, etc.) on standard basic electronics to encode. The printed circuit board, which is occupied on both sides, has a corresponding one depending on the keyboard Number of microswitches. With a standard diatonic harmonica you can for example 28 microswitches and complementary monolithic circuits used as electronic components for sound switching. This results in 28 microswitches and as many switchings as 56 tones.

According to the invention, it is particularly advantageous that with the Diaton converter a key coding can be made. There are those on both sides of the Circuit board existing conductor tracks arranged in the rail cross system. Through this lead, for example, the upper side conductor tracks from the electronic components of left to right, while the underside conductors from top to bottom to the organ electronics be directed. Via solder pin connections are after drilling through the circuit board Upper and underside of the conductor tracks connected to one another in such a way that each Key can be encoded. An economical implementation of this coding can take place in that the holes are made using templates. So are for example With the choice of 28 push buttons by assigning two tones to each push button 56 conductor tracks to call. A (push) tone wg «and a (pull) tone can be activated via a first push button nbw can be obtained while another push button, for example, the (pressure) sound wa # "and a (pull) tone zgt delivers. These designated conductor tracks are running on the electronics board top from left to right.

The automatic sound switching is understandably a mechanical one Switching sound is generally preferable because the player is fully focused on the interpretation of the game and not burdened by pressing the switch plate will. Due to the arrangement of the Leitarplatte by means of spacer brackets directly over the Air flaps and the arrangement of the spring steel brackets between air flaps and Microswitches also provide distance compensation, i.e. safe actuation the air flaps allows. By pretensioning the spring steel bracket, this can be done Pressure torque can be varied so that the finger load of the player as desired is optimized.

According to another development of the inventive concept, can two harmonicas can be connected to an electronic organ at the same time.

To make the joint connection of two harmonicas is It is advantageous to provide an adapter, which at the same time to avoid a has mutual influencing of the two harmonicas blocking diodes. The adapter is conveniently designed such that it has two 'sockets for the Connection with the two accordions and a pin plug for connection to the organ having. This enables quick connection by coupling. In the same way, it is easy to quickly separate the parallel recording.

To the electronic organ in its mode of operation in the greatest possible way Use scope, additional switching elements, for example at the top of the diatonic converter. These can preferably be designed as a rocker switch. In the function of the switches, different derive known combinations through which timbres, background sounds, rhythms, Sound connections and sound effects (piano, spinet, wah-wah, etc.) can be achieved can.

According to the invention, there is also the possibility of installing a second diatonic converter on the bass side of the instrument also the bass side the electronic organ to play synchronously, with the original sound in the diatonic Harmonica is preserved. In this case, the connecting lines are through the bellows interior out.

According to the invention, the connection is made to the multi-pole socket of the first diaton converter (melody side), so only a single multi-pole Cable connects to the electronic organ.

By coupling several octaves together on a button system, the combined musical instrument according to the invention provides a multi-choral fullness of notes achieved that with the conventional piano keyboard of the chromatic accordion can hardly be reached, whereby the sophisticated handle system of the diatonic harmonica contributes decisively to the achievement of this fullness of tone. The original sound of the diatonic Harmonica persists using this invention, making this real Folk instructor in its effect despite the combination with an electronic organ is fully preserved.

Finally, according to the invention, the possibility is given by a simple, unusual coupling of the automatic bass (bass chord) to the melody keyboard (Choir switch) the automatic bass chord with the melody hand without a bass-diaton converter to play along. By switching the melody organ electronics on or off, you can to the original harmonica the automatic bass chord (organ) - with or without rhythm - can be used in full, which makes another variant of the Diaton playing style possible is. That means, with the melody, the bass chord becomes correct with or without rhythm carried along. As a result, only one man can go back to playing his harmonica Accompany your needs or preferences with a bass chord and rhythm (drums).

This automatic bass and rhythm coupling according to the invention is particularly beneficial for people with left-hand disabilities, i.e. for people which cannot operate the bass side of the instrument or only inadequately. This handicap can be physical in nature, with the hand absent or restricted from movement is. But it can also result from a lack of skill on the part of a layperson or a beginner exist. Nevertheless, these people can also use such an instrument produce the same effects as a professional player, for example.

In the case of this coupling according to the invention, there is then no need also equipping the diatonic harmonica with a bass-diatonic converter, so that an additional saving is made as a result.

The subject matter of the invention is described below with reference to the attached Exemplary embodiments illustrated in the drawing are explained in more detail. It shows: Fig. 1 a combined musical instrument according to the invention, FIG. 2 is a block diagram of the Combined musical instrument according to Fig. 1-, Fig. 3 is a partial section through an accordion retrofitted according to the invention with a tone in the rest position, Fig. 4 shows a section as in FIG. 3 with an actuated sound button, FIG. 5 shows a circuit diagram a single sound switch, for an electronic (automatic) sound switch, 6 shows a partially sectioned view of the control element for the automatic Sound switching, Fig. 7 a diagram as in Fig. 5, for a mechanical sound switching, 8 shows a section along line VIII-VIII from FIG. 9, FIG. 9 shows a view the actuating elements of a mechanical sound switch, Fig. 10 an adapter for connecting two harmonicas to organ electronics, Fig. 11 is a circuit diagram of an adapter according to FIG. 10.

As can be seen from Fig. 1, the inventive combined Musical instrument consisting of a sound key 11 and a bellows 12 having diatonic harmonica 1 and an electronic organ 6. On the melody side of the Harmonica 1, a diatonic converter 2 is arranged, which about a plug 3, and a connecting cable 4 with a socket 5 of the electronic Organ 6 is connectable. On the organ 6 there is also a sound swell via cables 9 and 10 7 and a stop switch 8 connected.

From the diagram in FIG. 2 it can be seen that the keys 11 the diaton converter 2 is actuated, which in turn activates the organ 6.

With the stop pedal 8, the organ can also be operated directly from a greater distance of the accordion player from the organ through this the organ zubzw. be switched off.

As can be seen from FIGS. 3 and 4, the diaton converter inter alia a circuit board 13, which is directly above the sound-generating Air flaps 14 of the harmonica is arranged.

The tone keys 14 are each via a tone key lever 15 Button lever joint'l6 with built-in return spring and a button lever 17 with the tone button 11 firmly connected. The assembly of sound button 11 - air flap 14 is Articulated via the button lever joint 16 on the wall 18 leading to the bellows space.

On the circuit board 13 are contact buttons 19, which are preferably Microswitches are attached in a known manner. Between circuit board 13 and air flap 14 a spring steel clip 20 is arranged.

This spring steel bracket 20 has a multiple angled shape, and is at its one end each next to a microswitch anchored in the circuit board. Its other end extends to the back of the air flap 14 approach. An essentially central step-shaped bend of the spring clip 20 engages around the top of microswitch 19 in such a way that, as can be seen from FIG is, upon actuation of the sound button 11, the air flap 14 the spring steel bracket (20) in such a way pushes back that this actuates the microswitch 19 via the middle stage. -The Automatic sound switching shown schematically in FIG. 5 consists in that The luminous flux is transmitted via a light barrier 21 actuated pneumatically via the bellows 12 between a light emitting diode 22 and a phototransistor 23 interrupted or again will be produced. This affects an IC driver stage 24, which in turn a different IC module was included. The IC module 25 in turn is on the one hand with plug connection 3 (with power supply from and to the organ electronics) the tone button 11, a choir switch 27, possibly a bass chord switch 52 and a blocking diode 26 and on the other hand preselected with coding points 28 (solder pins) Sound lines 29 (sound E) and 30 (sound G) and in sound lines 29 and 30, respectively provided blocking diodes 26 connected. When the bellows 12 is pulled (negative pressure) the light barrier 21 is withdrawn, whereby the light from the light-emitting diode 22 can impinge on the phototransistor 23. As a result, the IC driver stage 24 and through this the IC module 25 activated. At the same time Pressing the tone button 11 and the choir switch 27 closed becomes the IC module 25 establish the connection with audio line 30 (tone G). Is now by squeezing of the bellows 12 generates an overpressure in this, so the light barrier 21 closed, whereby the light beam is interrupted by the light emitting diode. Through this the IC driver stage 24 is influenced accordingly, whereby the necessary switching of the IC module 25 takes place, so that the sound line 29 (sound E) is now in the Circuit is included.

As can be seen from Fig. 6, the light barrier 21 consists of a Piston 31, which is arranged axially displaceably in a cylinder 32. Of the advantageously formed from a brass sleeve cylinder 32 is at its one End connected to a pressure hose 33, which in the bellows interior 34 reaches in. In the cylinder 32 there is a limiting pin (35) for limiting the travel of the piston 31 is provided so as to protrude into the interior of the cylinder. Like the cylinder 32, the phototransistor 23 and the light-emitting diode 22 are also on the circuit board 13 a limiting bracket 36 is provided to limit the extension path of the piston 31. When generating overpressure in the bellows interior 34, this overpressure is caused by the Transfer pressure hose 33 into the interior of the cylinder 32, whereby the piston 31 is pushed out of the inside of the cylinder until it hits the limit bracket 36 pending. On the other hand, if there is negative pressure in the Baig interior 34 by the simultaneously generated negative pressure in the cylinder 32 of the piston 31 into the The inside of the cylinder is drawn in until it strikes the limiting pin 35.

From the circuit diagram shown in Fig. 7 to a single mechanical Sound switching can be seen that for switching from the audio line 29 (Tone E) on 30 (tone G) an actuator plate 37, which with a mechanical Tonumschalttaste 39 cooperates, is provided. When pressing the flush plate 37 the mechanisce tone switch button 38 is actuated, whereby if present a negative pressure in the air bellows 12 and at the same time pressing the tone button 11 the Tonleituny 30 (tone G) is selected. When the actuating plate 37 is released accordingly tone line 29 (tone E) is selected.

The structure is shown in FIGS. 8 and 9. the mechanical sound switching visible. This consists of arranged on the side plate 39 (bass connection plate) (Micro) changeover switches 40, their connection line to the keyboard on the right-hand side the harmonica is guided through the bellows interior.-On the side plate 39 a bearing block 41 is attached, on which an elastic plate 42 a Actuating plate 43 is fastened by means of screws 44, for example. To one special To achieve good rigidity of the actuator plate 34, this is preferably off Plexiglas or similar, relatively inelastic material. Each- because at the level of the microswitch 40, the plate has elastic elements on the inside 45, which, for example, rubber buffers or other elastic material can be shaped buffers or elastic strips.

Fig. 10 shows an adapter 46 for connecting two diatonic ones Harmonica on an electronic organ. The adapter 46 consists essentially from a small housing 47, which on a two-lane motherboard 48 two Has sockets 49 and 50 for receiving the plugs of the two accordions. On the narrow side of the housing 47, a pin connector is provided as an organ connection. As can also be seen from FIG. 11, which shows a circuit diagram of the adapter is, the adapter has blocking diodes 26 which influence one another of the two harmonicas.
