Definitions

  • the invention relates to a pickup system for a musical instrument with an instrument body, with a bridge for supporting the strings of the musical instrument and with an acoustic transducer, for example a membrane microphone and one in front of the sound-absorbing one Side of the converter lying, airtight closed air chamber.
  • an acoustic transducer for example a membrane microphone and one in front of the sound-absorbing one Side of the converter lying, airtight closed air chamber.
  • Such bridges with an integrated pickup system are used in stringed instruments used, especially in guitars, electric guitars and basses, Mandolins and the like. These bridges are used for acoustic Stringed instruments without feedback problems, as is usually the case with microphones occur, amplify or z. B. with electric guitars and bass guitars to offer the magnetic pickups a second sound variant because of a pickup in the bridge also several vibrations of the instrument body are also transmitted.
  • AT-PS 388 071 should also be mentioned here, which has a bridge with a pickup shows and describes.
  • the pickup has a housing in which a membrane microphone is housed. In front of the sound absorbing side of the Membrane microphones lie in a closed, chamber-like air space or Air gap. This is at least partially elastic and essentially limited gas impermeable material.
  • the housing, which is open on one side is with the formation of the chamber-like air space or air space gap closed a closure which is formed from this elastic material.
  • This elastic material has a preferred density.
  • This pickup is arranged in a recess of the web.
  • the invention aims to achieve this known constructions to improve, mainly the frequency response and the dynamics of the vibrations or the conversion thereof into electrical Signals.
  • the invention proposes that the air space across the length of the strings and across from those next to each other strings occupied zone stretches and the strings carrying the strings Web forms a boundary wall of the air space chamber or on one Air chamber bounding wall is arranged.
  • Appropriate configurations the invention are set out in the subclaims.
  • Fig. 1 shows an oblique view of a guitar with an instrument body 1 and six strings 4 lying side by side, extending over zone 2 of the instrument extend. This zone 2 is the area of the instrument in which the mentioned Strings 4 lie. Near one anchoring point 3 of the strings 4 is the Web 5, to which the present invention relates and which is shown here in FIG. 1 is only shown schematically. This figure only serves to show which Field of a stringed instrument, the invention relates without the Invention to be limited to a specific stringed instrument.
  • the bridge 5 on which the strings 4 lie is parallel to the front side 6 of a bearing block 7, which here is a support part forms and which is fixed on the instrument body 1 and also for Anchoring one end of the strings 4 is used.
  • This web 5 is from the front side 6 of the bearing block 7 or support part somewhat distanced, so that here shallow air chamber 8 is recessed from the three narrow sides by one elastic material 9 are formed, which seals the air chamber 8 tightly.
  • This airspace chamber has the shape of a flat cuboid, the The longitudinal extent of this air space chamber is transverse to the strings 4 and extends over zone 2, in which the strings 4 of the instrument lie.
  • This Air chamber 8 is sealed airtight on all sides.
  • the airspace chamber 8 is designed here so that the pressure of the strings 4 is not on the elastic Material, but is derived via the web 5, which is a broad side of the here flat, cuboid air chamber 8 forms. Thanks to this construction low frequencies are transmitted very well, since at least one is the air chamber 8 final part vibrates slightly and thereby the resonance frequency comes to lie deep.
  • the tightly closed air chamber 8 is limited by the web 5 and the Face 6 of the support part or bearing block 7 as broad sides of this air space chamber, further from the contact surface 25 of the web 5 and a U-shaped frame-like part made of elastic material 9, the two parallel legs are parallel to the plane of the drawing in Fig. 2 and its legs connecting The middle part is perpendicular to the drawing plane in Fig. 2.
  • FIG. 3 Another embodiment of the invention is illustrated in FIG. 3 the air space chamber 8 through the instrument body 1 or its surface limited, which forms a boundary wall 13 of the air chamber 8.
  • the others Boundary walls of this air chamber 8 are by a on the instrument body 1 fixed support part 11 formed, which is also the anchor the strings 4 serves.
  • this support part 11 is also the membrane microphone 10 stored.
  • the bridge or comb 5, on which the strings rest, stands up the surface of the support member 11, above that area in the the air space chamber 8 extends. This formation of the web is suitable for a guitar or mandolin.
  • the air space chamber 8 is also tightly closed here, the membrane microphone is also used airtight and is for Air space chamber 8 open.
  • the electrical connections 12 are on the outside guided.
  • FIG. 4 and 5 illustrate a web according to the invention for an electrical Violin.
  • the web 5 carrying the strings 4 is on a recessed one Boundary surface 13 bridging and covering plate 15 is arranged. This plate 15 closes the air space chamber 8 tightly.
  • the membrane microphone 10 is defined here in the instrument body 1.
  • the air space chamber 8 with an additional microphone 10 damping material, such as a felt 16 filled to the strong proportions dampen high frequencies that predominate in string instruments.
  • the Bridge 5 is designed like a conventional violin, it can be on the plate 15 glued or, as usual with violins, held only by the string tension his. Plate 15 and web 5 can also form a one-piece component.
  • the membrane microphone is to achieve the design 10 arranged laterally of the air space chamber and with this via an inner Channel 17 connected.
  • the electrical connections 12 of the membrane microphone 10 are down into the instrument body and over corresponding Channels led to the designated contacts.
  • the Support part 11 which here contains the air space chamber 8 as a whole, are the Strings 4 anchored.
  • this spar 18 are the number of strings 4 corresponding to vertical grub screws 21 set.
  • a nut 22 is screwed onto each set screw 21, which here has two superimposed, circumferential grooves 23. These nuts are designed as knurled nuts.
  • the strings 4 lie in these grooves 23 and describe an acute angle between their anchoring points at the ends both down and to the side.
  • the spar 18 is on the Support part 11 pressed and fixed in position.
  • One side guide 20 serves as a stop.
  • This lateral guide 20 is advantageously by means of Screws 24 adjustable and thus allows adjustment of this spar 18 across the strings 4 to correct a possibly faulty or warped Instrument neck.
  • This construction makes the string height adjustment possible possible without tools, on the other hand, the transmission of the string vibrations on the web and thus on the air chamber 8 through the light vertical construction optimally guaranteed.
  • an airtight air chamber 8 is provided.
  • an airborne sound or Sound pressure which from the attached in the web, membrane side to the air space 8 open membrane microphone 5 (e.g. a miniature electret condenser microphone), designed as a pressure receiver, in an electrical signal is changed.
  • membrane microphone 5 e.g. a miniature electret condenser microphone
  • the airtight closed Air chamber 8 can not penetrate external noise from the outside. Thereby a high feedback distance is ensured.
  • the one ends of the strings are fixed on the support part 11 and anchored. It is within the scope of the invention to have these ends on the instrument body set.
