Definitions

  • the present invention relates to an electroacoustic pickup system for a stringed instrument having at least two arranged in the region of the strings, optionally connectable to a signal output pickup elements.
  • the invention further relates to a stringed instrument equipped with such a pickup system, in particular an electric guitar or an electric bass.
  • pickup systems In the case of stringed instruments, in order to pick up the acoustic sound produced by the vibrating strings and to convert it into amplifiable electrical signals, there are generally provided pickup systems there. These pickup systems generally have pickup elements as well as a circuit connecting them to a signal output, wherein at the signal output the electrical signal is tapped and further processed, e.g. can be amplified before it is then played back on speaker systems.
  • more than one pickup element in many cases at least two such pickup elements, are arranged in the area of the vibrating strings, which can be connected individually or else combined with the signal output via a simple switching element, for example a toggle switch.
  • a simple switching element for example a toggle switch.
  • the individual pickup generates one own sound and gives the instrument its own characteristic tonal touch. This effect is exploited in the playing of the instrument by selectively selecting the individual pickup elements for individual pieces of music, sometimes for individual passages within a piece of music, and interconnecting them with the signal output.
  • a simple selector switch which may be a toggle or rotary switch, allows selection of only a few combinations of existing pickup elements.
  • guitars of the well-known series Les Paul of the manufacturer Gibson in which usually two electromagnetic pickups with two offset in their spatial orientation arranged pickup coils, the so-called humbucker pickups are arranged, selector switch provided the selection respectively separate one of the two humbucker pickups and in a third selection position allow the selection of both humbucker pickups, in each position with both coils of the respective pickup.
  • each of the pickups is controlled individually via a selector switch, so as to select three different sound variations of the guitar can.
  • an electro-acoustic pickup system of the type mentioned above is to be improved so that it offers a greater degree of possibilities of setting different sounds or sounds of a stocked with this pickup sonic instrument.
  • the essential idea of the invention is to provide this interconnection via a relay connection instead of a direct interconnection of the pickup elements via a simple switching element such as a rotary or toggle switch.
  • a relay connection can then be addressed in particular by means of a control (cf., claim 8), which can be set and actuated in particular via an operating element (cf.
  • the controller is provided with a correspondingly menu-guided software, the advantageously provided operating element can be comparatively simple, e.g. a combined rotary switch and button to control and select individual menu items.
  • an operating element may e.g. be used instead of a conventional rotary switch, with the previous selection of a few possible alternatives Tonab chorusverscnies has been performed.
  • the Relaisverscnies can be carried out together with the possibly to be provided control in a very small size and accordingly accommodated in the stringed instrument easy.
  • the accommodation can be done in the body of the instrument, which often contains not yet fully utilized cavities for circuit elements anyway.
  • the pickup elements according to the invention may in particular contain electromagnetic pickups, piezoelectric pickups and MIDI pickups, in particular also combinations of these elements. But it is equally possible to use microphones as a pickup, especially for pure acoustic instruments, such as acoustic guitars. Here, too, there is basically the possibility of producing different sound effects by means of different mounting locations of the microphones on the instrument, which effects can be selected with a relay connection according to the invention having a high degree of freedom.
  • both those with one coil per pickup can be used as well as those with two or even more differently oriented coils.
  • each of the individual coils to evaluate their own pickup and thus can basically individually via a corresponding relay in the relay connection switched on and off and thus be given separately to the signal output.
  • the pickup system further comprises means for phase shifting individual pickup elements to be interconnected with each other.
  • the pickup system further comprises means for phase shifting individual pickup elements to be interconnected with each other.
  • two coil elements of a so-called humbucker can be connected in phase or in opposite phase to each other, which leads to clearly different sound results.
  • the electroacoustic pickup system is preferably provided with a controller, then this may in particular also have a data memory for storing configuration patterns of the pickup elements corresponding settings.
  • a musician who plays an instrument equipped with such a pickup system to store certain, from the variety of presets made possible by the system according to the invention selected sound settings or specifications, which then read out during the game by simply operating the control of this from the data memory and the relay interconnection and possibly also existing further means for attenuation or amplification the signals and for generating phase shifts can be adjusted.
  • the inventive system for musicians completely new ways to use their instrument with a variety of new and even during the game quickly adjustable and correspondingly changeable sound effects.
  • the relay in the Relaisverscnies are designed as a surge relay, on the one hand the energy consumption is kept low (with surge relay energy is only needed when switching the respective relay) and thus on the other hand in a possibly occurring failure of the supply energy during the game a defined setting of the electro-acoustic Pickup system is maintained and the system does not fall into an unwanted and undefined state.
  • relays in addition also arranged on the string instrument switching and / or control elements, such as. Volume control or the like, optionally to interconnect, e.g. Assign to different pickups via certain relay switch positions. As a result, further degrees of freedom are achieved.

  • rotary encoders 10, 11, 12 can be seen with which in conventionally wired guitars, for example, the amplitude of the output signal (thus the volume) can be adjusted as well as other parameters, in particular with one of the rotary control or Rotary switch a selection of the individual pickups 7, 8, 9 can be made for the provision of the output signal.
  • the pickups 7, 8, 9 shown here are electromagnetic pickups, each with a single coil (so-called single-coil pickup).
  • FIG. 3 is another form of electric guitar 1 'shown, here the well-known model Les Paul of the supplier Gibson. Again, only a section can be seen with the body completely shown 2 'and a portion of the web 3'. In this guitar type, the strings 6 also run from the body 2 'over the bridge 3' up to the head of the guitar, not shown here, where they accumulate comparable to other types of guitars in their tension adjustable to vertebrae.
  • the strings 6 are fixed here with their one end in a fastening 13 on the body 2 'and run from there via a guide 14 in the direction of the guitar head.
  • the embodiments according to the invention of the different types of guitars are similar to the hitherto customary.

  • the switch corresponding signals of the individual or a combination of the pickups were given to the output to an amplifier, with which the guitar sound was amplified and finally played through speakers.
  • the pickup system of the invention works differently here.
  • a relay connection is provided, with the individual of the pickups 7, 8, 9 and 15, 16, in the occupied with two coils pickups 15, 16 even the individual coils can be selectively switched on.
