Abstract

Music instrument amplifier equipment for amplifying the musical instrument sound/tone and for reproducing this tone via loud speakers. The sound volume of this reproduced tone frequently does not correspond to the demands of musicians or engineers, resulting in effect devices being connected between the musical instrument and the amplifier which bestow on an electronic basis, an improved sound. An electret-microphone is placed a distance from the amplifier's loudspeaker and generates a feedback signal which is sent via a cable to the input of the amplifier.

Description

Es ist bekannt, dass das Klangvolumen von Musikinstrumentenverstärkern dadurch verbessert werden kann indem das Signal, welches vom Musikinstrument erzeugt und durch Tonabnehmer in elektrische Schwingungen umgewandelt in den Verstärkereingang gelangt mit für den Menschen nicht bemerkbaren zeitlichen Verzögerung erneut in den Verstärkereingang gelangt. Dazu ist es allerdings nötig, aufwendige Effektgeräte zwischen Musikinstrument und Verstärker zu schalten. Viele Musiker vor allem Gitarristen möchten auf solche Effektgeräte verzichten und nur mit zum Beispiel Gitarre und Verstärker kostengünstig ein gutes Klangvolumen erzeugen. It is known that the sound volume of musical instrument amplifiers can be improved as a result by the signal generated by the musical instrument and by pickups in electrical vibrations converted into the amplifier input arrives with a time delay that is not noticeable to humans reached the amplifier input again. However, this requires the use of elaborate effects devices Switch musical instrument and amplifier. Many musicians especially guitarists want to be on such No effects devices and only a good sound volume with, for example, guitar and amplifier produce.

Der im Patentanspruch 1 angegebenen Erfindung liegt das Problem zugrunde, dass eine Verbesserung des Klangvolumens von Musikinstrumentenverstärkeranlagen nur durch kostenungünstige Effektgeräte erzielt werden kann. Diese Effektgeräte möchten viele Musiker nicht einsetzen. The invention specified in claim 1 is based on the problem that an improvement in Sound volume of musical instrument amplifier systems achieved only by inexpensive effects devices can be. Many musicians do not want to use these effects devices.

Dieses Problem wird durch die im Patentanspruch 1 aufgeführten Merkmale: "dass ein Elektret-Mikrofon einige Meter vom Wiedergabelautsprecher entfernt den ankommenden Ton akustisch erfasst, ihn in elektrische Schwingungen umwandelt und dieses Signal erneut in den Eingang des Verstärkers über Kabel schickt", gelöst. Bei diesem System handelt es sich um die Ausnutzung der unterschiedlichen Geschwindigkeiten der Tonsignale. Das Signal von der Gitarre in den Eingang des Verstärkers bewegt sich mit annähernder Lichtgeschwindigkeit das aus dem Lautsprecher tretende Tonsignal bewegt sich hingegen mit Schallgeschwindigkeit zum Mikrofon, wo es wiederum "verdoppelt" in den Eingang des Verstärkers gelangt. Diese zeitliche Differenz wird von menschlichen Sinnen nicht wahrgenommen, nur das Klangvolumen wird als besser erkannt. Billige, einfache Gitarrenverstärker mit Wiedergabelautsprechern wurden von Gitarristen getestet und das Ergebnis war beim Hinzhuschalten des hier beschriebenen Systems - eine deutliche Verbesserung des Klangvolumens zur Zufriedenheit der Musiker. This problem is solved by the features listed in claim 1: "that some electret microphone Meters away from the playback speaker, the incoming sound is recorded acoustically, and it is converted into electrical Converts vibrations and sends this signal again to the input of the amplifier via cable ", solved. This system uses the different speeds of the Sound signals. The signal from the guitar to the input of the amplifier moves with approximations Speed of light, however, the sound signal emerging from the loudspeaker also moves Speed of sound to the microphone, where it in turn "doubles" into the input of the amplifier arrives. This time difference is not perceived by human senses, only the volume of sound is recognized as better. Cheap, simple guitar amps with playback speakers have been created by guitarists tested and the result was a clear one when the system described here was added Improvement of the sound volume to the satisfaction of the musicians.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, dass Kosten für Effektgeräte eingespart werden und der "natürliche" Klang des vom Musikinstrument erzeugten Tones erhalten bleibt und nicht elektronisch verfälscht wird. The advantages achieved with the invention are, in particular, that costs for effect devices are saved and the "natural" sound of the sound produced by the musical instrument is preserved and not is electronically falsified.

Eine vorteilhafte Ausgestaltung der Erfindung ist im Patentanspruch 2 angegeben. Dieses Mikrovon in einen Drehknopf eines Spezialdrehwiederstandes einzubauen welcher sich in dem entsprechenden Musikinstrument befindet (Elektrogitarre), Dieses macht besondere Vorteile, da dieses System nicht als solches erkennbar ist, leicht zu bedienen ist und geringen Aufwand zur Installation benötigt. Das benötigte Tonsignal erhält das Mikrofon bei Bühneneinsatz von den Monitorlautsprechern die direkt vor den Musikern zur Selbskontrolle positioniert sind. An advantageous embodiment of the invention is specified in claim 2. This microof into one Install rotary knob of a special rotary resistor which is in the corresponding musical instrument located (electric guitar), This has special advantages because this system is not recognizable as such is easy to use and requires little installation effort. The required sound signal receives that Microphone when used on stage by the monitor speakers directly in front of the musicians for self-control are positioned.

Auf Zeichnungen wird hier verzichtet, da die Beschreibung zum Verständnis der Probleme ausreicht. Drawings are omitted here because the description is sufficient to understand the problems.

Claims (2)

1. Musikinstrumentenverstärkeranlagen verstärken den von Musikinstrumenten erzeugten Ton und geben diesen Ton über Lautsprecher wieder. Das Klangvolumen dieser wiedergegebenen Töne entspricht häufig nicht den Ansprüchen der Musiker oder Technikern. Daher werden zwischen Musikinstrument und Verstärker sogenannte Effektgeräte geschaltet, die auf elektronischer Basis den Tönen einen besseren Klang verleien. Diese Geräte sind kostenaufwendig und beanspruchen eine eigene Stromversorgung (meist Batterien) dieses ist oft sehr hinderlich bei Transport und Arbeit auf der Bühne, dadurch gekennzeichnet, dass ein Elektret-Mikrofon einige Meter vom Wiedergabelautsprecher entfernt den ankommenden Ton akustisch erfasst, ihn in elektrische Schwingungen umwandelt und dieses Singnal erneut in den Eingang des Verstärkers über Kabel schickt. 1. Musical instrument amplifier systems amplify the sound produced by musical instruments and reproduce this sound via loudspeakers. The volume of these reproduced tones often does not meet the demands of musicians or technicians. Therefore, so-called effect devices are switched between the musical instrument and amplifier, which give the tones a better sound on an electronic basis. These devices are expensive and require their own power supply (usually batteries), which is often very cumbersome for transport and work on stage, characterized in that an electret microphone acoustically detects the incoming sound a few meters from the playback speaker and converts it into electrical vibrations and sends this signal back into the input of the amplifier via cable. 2. System nach Patentanspruch 1, dadurch gekennzeichnet, dass dieses Mikrofon in einen Drehknopf eines Drehwiederstandes eingebaut ist. Dieser Drehwiederstand ist wie gewöhnlich auch in einer Elektrogitarre eingebaut. Hierbei handelt es sich um einen Drehwiederstand der in der Achse eine Bohrung aufweist. Durch diese Bohrung werden zwei Kabel geführt, die an dem Zapfen der Achse an zwei Kontaktflächen von einander isoliert festgelötet sind. Die anderen Enden der Kabel sind einmal mit dem Schleifkontakt des Drehwiederstandes verbunden und das andere Ende des Kabels mit der Wiederstandsschicht.
In dem Drehknopf ist das Mikrofon fest eingebaut, die Anschlüsse des Mikrofons sind an zwei Kontaktflächen gelötet, die voneinander isoliert eine Haltebuchse bilden die auf den Zapfen des Drehwiederstandes samt Drehknopf gesteckt wird. Dabei wird durch entsprechende Führung der Kontakt zu den auf dem Zapfen des Drehwiederstandes befindlichen Kontaktflächen hergestellt.
Mittels diesen Drehwiederstandes wird dann die Empfindlichkeit des Mikrofons geregelt. Das durch das Mikrofon aufgenommene Singnal wird dann durch eine extra Leitung zum Eingang des Verstärker geschickt. 2. System according to claim 1, characterized in that this microphone is installed in a rotary knob of a rotary resistor. As usual, this rotary resistor is also built into an electric guitar. This is a rotational resistance that has a hole in the axis. Two cables are routed through this hole, which are soldered to the journal of the axle and insulated from one another on two contact surfaces. The other ends of the cable are connected once to the sliding contact of the rotating resistor and the other end of the cable to the resistance layer.
The microphone is permanently installed in the rotary knob, the connections of the microphone are soldered to two contact surfaces, which form a holding bush that is insulated from each other and which is plugged onto the pin of the rotary resistor together with the rotary knob. Appropriate guidance is used to establish contact with the contact surfaces located on the journal of the rotary resistor.
The sensitivity of the microphone is then regulated by means of this rotational resistance. The signal picked up by the microphone is then sent through an extra line to the input of the amplifier.
