Beschreibung des Patentanspruchs Description of the claim
Titel: Fallrgeräuschsimulator anwendungsgebiet: Die Erfindung stellt einen Simulator dar, der auf elektronischgr Basis akustisch verschiedene Fahrgeräusche erzeugt und in Tonstudios und/oder im Modellbau Verwendung finden kann.Title: Fall noise simulator area of application: The invention represents a simulator that electronically generates acoustically different driving noises generated and can be used in recording studios and / or in model making.
Zweck: Im Modellbau und im Unterhaltungssektor besteht die berechtigte Forderung, diverse Fahrgeräusche möglichst naturgetreu nachzuahmen. Um diese Forderung erfüllen zu können, wurde von mir der Fahrgeräuschsimulator entwickelt. illit ihm kann auf einfache Weise das naturgetreue Falirgeräusch, z.B.Purpose: In model making and in the entertainment sector, the legitimate one exists Demand to imitate various driving noises as faithfully as possible. To this requirement To be able to meet, the driving noise simulator was developed by me. illit him the lifelike fallout noise, e.g.
von Verbrennungsmotoren in Kfz. und Schiffen, simuliert werden. of internal combustion engines in motor vehicles. and ships, can be simulated.
Stand der Technik: Bisher war eine fahrgeräuschähnliche Simulation nur mit sehr aufwendigen Synthesizerbaugruppen möglich.State of the art: So far there was a simulation similar to driving noise only possible with very complex synthesizer assemblies.
Aufgabe: Der Erfindung liegt die Aufgabe zugrunde, die lvlöglichkeit zu schaffen, in der Unterhaltungselektronik sowie im iWlodellbau das charakteristische Geräusch von j'jotoren mit geringem Aufwand nachzuahmen.Task: The invention is based on the task of the possibility to create the characteristic in entertainment electronics as well as in iWlodellbau Imitate the sound of j'jotoren with little effort.
Lösung: Die Aufgabe wird mit dimer Erfindung dahingehend gelöst, daß ein elektromechanischer Generator als Grundtonerzeuger Verwendung findet. Dieser aussteuerungsabhängige Grundton wird mittels spezieller Filter in die gewünschten motorengeräuschsimulierenden Töne umgewandelt. Sollte eine mehrkanalige synchrone Tonerzeugung notwendig sein, so sind alle Grundton- und Filterbaugruppen mittels Entkopplern zusammenzuschalten und den Zwischen- oder Endverstärkern bzw. einem Nischpult zuzuschalten.Solution: The object is achieved with dimer invention to the effect that an electromechanical generator is used as a fundamental tone generator. This The level-dependent fundamental tone is converted into the desired tone using a special filter engine noise-simulating tones converted. Should a multi-channel synchronous If tone generation is necessary, all fundamental tone and filter assemblies are by means of To interconnect decouplers and the intermediate or power amplifier or a Switch on the niche desk.
Erzielbare Vorteile: Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, daß statt eines technisch sehr aufwendigen Gerätes ein Gerät produziert werden kann, das in seiner Funktion und Bauweiße keinen großen technischen Aufwand erfordert und auch sehr einfach und schnell an Ort und Stelle gewartet werden kann. Außerdem ist dieser von mir entwickelte Fahrgeräuschsimulator auf Grund seines geringen Platzbedarfs in allen Toneffektgeräten als Baugruppe oder Steckeinheit zu integrieren.Achievable Advantages: The advantages that can be achieved with the invention exist especially in the fact that instead of a technically very complex device, a device can be produced, which in its function and construction does not have any major technical features Requires effort and can also be serviced very easily and quickly on the spot can. In addition, this driving noise simulator developed by me is due to his little space required in all sound effect devices as a module or plug-in unit to integrate.
Dieser Fahrgeräuschsimulator kann auch als Sologerät eingesetzt werden.This driving noise simulator can also be used as a standalone device.
Beschreibung eines Ausführungsbeispiels: Ein Ausftilirungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben; Der Fahrgeräuschsimulator besteht grundsätzlich aus drei Hauptteilen: Aus dem regelbaren Grundtonerzeuger mit Endkoppler (Zeichnung Fig. 1) Aus dem regelbaren aktiven Doppel-T-Filter (Zeichnung Fig 2) Aus dem abschließenden Verstärkerteil (Zeichnung Fig. 3) Fig. 1 - Erläuterung: Durch anlegen einer Gleichspannung an die Pole +/-von UE und schließen des Schalters S1, sowie betätigen des Potis P1, kann der elektromechanische Grundtonerzeuger (permanentmagnetischer Gleichstrommotor) den brfordernissen entsprechend in der Drehzahl geregelt werden. Ist eine bestimmte Grunddrehzahl erwünscht, kann diese durch schließen des Schalters S2 und einstellen mit Poti P2 realisiert werden. Durch die Umdrehung des otorläufers entstehen an den Polen drehzahlabhängige Induktionsspannungs spitzen, welche durch die beiden Kondensatoren in lftchtung Doppel-T-Filter ausgekoppelt werden.Description of an exemplary embodiment: An exemplary embodiment the invention is illustrated in the drawing and will be described in more detail below; The driving noise simulator basically consists of three main parts: The controllable one Basic tone generator with end coupler (drawing Fig. 1) From the adjustable active double-T filter (Drawing Fig. 2) From the final amplifier part (Drawing Fig. 3) Fig. 1 - Explanation: By applying a direct voltage to the poles +/- of UE and close of the switch S1, as well as actuating the potentiometer P1, the electromechanical fundamental tone generator (permanent magnetic direct current motor) according to the requirements in the Speed can be controlled. If a certain basic speed is required, this can by closing switch S2 and setting with potentiometer P2. By The rotation of the rotor results in a speed-dependent induction voltage at the poles spikes, which are decoupled by the two capacitors in the ventilation double-T filter will.
lig. 2 - Erläuterung: Die sc erzeugten Spannungsspitzen gelangen über ein ;iC-Glied zum regelbaren Doppel-T-Filter. Nach Ihrer Verstärkung, die mit dem Trimmer P4 eingestellt wird, werden sie frequenzabhängig über die beiden parallel geschalteten itoch- und Tiefpaßfilter zur Basis des Transistors rückgekoppelt. Durch verstellen des Potis P3 wird der rückzukoppelnde Frequenzbereich eigestellt.lig. 2 - Explanation: The voltage peaks generated sc get over a; iC element for the adjustable double-T filter. After your reinforcement with the Trimmer P4 is set, they are frequency dependent on the two in parallel switched itoch- and low-pass filter fed back to the base of the transistor. By Adjusting the potentiometer P3 sets the frequency range to be fed back.
Dadurch ist es möglich, den Induktionsspannungsspitzen, frequenz- und drellzahlabhängig sind, eine den Lauf,,erauschen von Verbrennungsmotoren charakteristischen Klang zu verleihen. Die Dimensionierung der Bauteile für die frequenzbestimmenden Filterteile kann den individuellen Gegebenheiten angepaßt werden.This makes it possible to reduce the induction voltage peaks, frequency- and are dependent on the double digit, a characteristic of internal combustion engines To give sound. The dimensioning of the components for the frequency-determining Filter parts can be adapted to the individual conditions.
ig. 3 - Erläuterung: Die vom Doppel-T-Filter an sLolektor des Transistors abgenommene Frequenz wird über das Poti P5, welches die Lautstärkeregelung ermöglicht, einem Verstärker zugeführt. Dieser Verstärker dient zur Erhöhung der Ausgangswechselspannung und bei mehrkanaligern betrieb als regelbarer Entkoppler.ig. 3 - Explanation: The one from the double T filter to sLolektor of the transistor The frequency picked up is controlled via the potentiometer P5, which enables the volume to be adjusted. fed to an amplifier. This amplifier is used to increase the output AC voltage and with multi-channel operation as an adjustable decoupler.
