Definitions

  • the invention relates to a device for converting the sound generated by a string of an instrument into an electrical signal, which will also be called a sound pick-up device for stringed instruments.
  • the sound of a stringed instrument is transmitted through a support, commonly called an eyelet, bridge or bone depending on the instrument, to the resonance body, ie. the table, the instrument to be amplified.
  • the vibration of the string passing through the table of the instrument can also be amplified using a transducer which transforms the generated sound into an electrical signal.
  • a sound pick-up device for stringed instruments and in particular for a gayageum.
  • the device is positioned under each string between the latter and the body of the instrument.
  • the device accommodates the string in a groove made in its upper part and converts the pressure due to the oscillation of the string into a vertical vibration. This vibration exerts a force on a piezoelectric element which generates an electrical signal corresponding to the vertical vibration.
  • a piezoelectric device is known for a stringed instrument and in particular for a guitar. It shows a saddle with, on the one hand, a grooved support for the maintenance of the rope and with, on the other hand, the piezoelectric, both arranged within a cavity of the instrument chassis.
  • the sound pick-up devices must integrate harmoniously and discreetly into the instrument.
  • the device is visible and unsuitable for other stringed instruments such as a harp.
  • the sound pickup devices must also be able to adapt to an existing instrument.
  • the positioning of the transducer and of its support element must ensure optimum transmission of the vibration of the instrument to the transducer as well as optimum transmission of the electrical signal to the amplifier.
  • the object of the present invention is thus to propose a sound pick-up device for stringed instruments meeting the aforementioned criteria.
  • the invention relates to a sound pick-up device for a stringed instrument
  • a part also called bridge
  • a transducer arranged within the part
  • said part being formed of a first face opposite to a second face, said first and second faces being connected by a wall, said wall having on a portion a cutout intended to form a support zone for the rope, said second face comprising a lug intended to be housed in a frame of the stringed instrument to keep it in position.
  • the invention also relates to the stringed instrument comprising this sound pick-up device which is positioned at the base of each string, preferably in a housing made in the chassis of the instrument.
  • the device can be adapted to different types of stringed instruments, even not designed for microphones at the base, by simple drilling made in the instrument.
  • the design of the device allows a natural positioning of the string between the walls of the housing and the cutout of the saddle with an optimal transmission of the vibration of the instrument as well as of the electrical signal to the amplifier. It also allows discrete positioning of conductors within the instrument.
  • the invention relates to a device for converting a sound generated by a string of an instrument into an electrical signal, said device will also be referred to below as a sound pick-up device.
  • the device according to the invention is applicable for any type of stringed instrument such as a harp, a kora, a zither, etc. and will be more specifically illustrated, by way of example, for a harp.
  • the stringed instrument 1 is provided with said device 2 at the base of each string 5, or at least on a majority of the strings, and said device 2 is accommodated within a housing 7 formed in the chassis of the instrument . It may thus be in the case of a harp housings provided in the soundboard.
  • the sound recording device visible from different angles at the figure 4 and cut to the picture 2 comprises a part 2 provided with a transducer 6 inserted within said part.
  • the transducer is embedded within the material constituting the part.
  • This material can be a polymer, a composite with a polymer matrix, a cermet, a metal or a metal alloy.
  • the transducer can be embedded in an ABS matrix (acrylonitrile butadiene styrene).
  • Part 2 has a first face 2a connected to a second face 2b by a wall 2c. The latter has on a portion a 2d cutout on which the string 5 rests when the part 2 is mounted in the housing 7 provided in the frame of the stringed instrument ( picture 3 ).
  • this cutout is in the shape of an arc of a circle but any shape allowing the support and the centering of the rope can be envisaged. It could also be a curvilinear or rectilinear notch cut into the wall.
  • the cutout and the periphery of the housing facing each other delimit a space in which the rope 5 passes under tension through a first orifice 8 placed at the bottom of the housing 7 formed in the frame.
  • the transducer is positioned next to this support zone of the string so as to optimally transmit the vibration of the string to the transducer.
  • the term "next to" means at a distance of between 0.1 mm and 5 mm, preferably between 0.1 mm and 2 mm with respect to the zone where the cord rests at the level of the cutout.
  • the second face 2b of part 2 has a lug 3 ( figure 5 ).
  • the latter stands perpendicular to the plane of the second face.
  • lug 3 When mounting part 2 in housing 7, lug 3 is inserted into a second orifice 9 provided in the bottom of housing 7, said second orifice 9 having dimensions substantially equivalent to those of the lug 3 so as to ensure that the part is held in position after assembly in the chassis ( picture 3 ).
  • this lug 3 also forms an output channel for the conductors 4 carrying the electrical signal from the transducer 6 to an amplifier (not shown).
  • the sound pickup device may be devoid of conductors physically connecting the transducer to the amplifier.
  • the sound pickup device is then provided with a transmitter, e.g. an induction coil, ensuring the wireless transmission of the electrical signal to the amplifier.
