Definitions

  • the present invention relates to a device for automatic Voices of a stringed instrument after the generic term of claim 1. It also relates to a method for automatic tuning of a stringed instrument after the The preamble of claim 8.
  • the tuning of instruments generally requires in addition to one a lot of time, especially from untrained, For example, hobby instrumentalists, must be applied.
  • the classical method of tuning "by hand” works the musician with a tuning fork, who by hitting sets the desired tone and adjusts by changing the String length or string tension the pitch of the respective String. By repeatedly striking the string and the tuning fork the result is adjusted until the desired one Mood of the string is reached. Based on this mood then the other strings are tuned.
  • the system is very welcome insofar as it is a swift one and allows automatic tuning and so in particular untrained musicians, but also the professionals a high degree decreases in effort.
  • the system has a not insignificant Disadvantage. It's overall big and chunky and requires significant changes to the body of the guitar, the on the one hand an influence on their acoustics (sound) and on the other hand on their handling (because of the changed weight) to have. Aside from that, the look of the guitar will also be in not insignificantly changed.
  • the invention proceeds. It has for its object to provide an improved device so far, which can be integrated into an instrument, in particular a guitar, with minimal influence on the sound properties and with as few and small elements. Furthermore, a method for automatic tuning of a stringed instrument is to be specified, which meets these requirements.
  • Claims 2 to 9 and 11 to 13 contain advantageous Further developments of the device or the method.
  • the core idea of the invention is the components of the device (which in this sense are also called system can) distribute on the instrument.
  • a guitar For example, not the entire device is placed in the body. So the head or neck also offers, albeit little, Room, for the (subtle) attachment of other components.
  • it can be arranged on guitars on the head anyway Means for adjusting the string length or voltage, which is the use of special parts reduced.
  • the guitar introduced fewer additional components become.
  • the signal transmission via the bus line can, for example, via a conventional bus cable, but also wireless, eg. About Radio or infrared, done.
  • control signals between the on an instrument part seated control and the at least one drive preferably guided over the strings serving as bus lines (Claim 2).
  • the strings of stringed instruments are made in many cases of a conductive material (metal) or are wrapped in a thread of one. alternative They can, if the sound permits, with a conductive Be coated material. This solution saves the use other lines laid in the instrument body would have to be. Besides the sound characteristics remains therefore not least the optics of the instrument.
  • strings are to be used as conductors, these are not electrically shorted together, have elements over which the strings are led together (for example, the bridge on a guitar) be designed so that they isolate the strings from each other.
  • elements made of a non-conductive material (eg ceramic) manufactured or coated with such, or other precautions of isolation must be made be (for example, interposed insulating discs, etc.).
  • the drive can be a motor, for example. Electric motor, he but can also work pneumatically or hydraulically.
  • an amplifier connected instrument eg an electric guitar
  • an amplifier connected instrument eg an electric guitar
  • Control can do this in a simple way by hitting one Page to be addressed.
  • An interface as provided according to claim 5 can, gives the possibility, from the outside - also afterwards - to feed software into the device. Furthermore, can via the interface different reference moods in the storage device can be entered to the instrument to be able to vote according to different schemes.
  • An as proposed in claim 6 embodiment of the device allows a stringwise tuning of the instrument. It can just as well be used as a drive by appropriate gear or similar devices for Adjusting each one string is switchable.
  • a development of the device according to claim 8 results a redundant system.
  • the device can also malfunction a string even further to tuning the instrument operated become.
  • the method according to claim 10 provides, as already stated above a solution to the above problem with regard to a It may be preferred with a device are operated according to one of claims 1 to 9, however not limited to such a device.
  • Claim 11 describes how preferred the strings of the instrument can be used as bus lines. Thereby do not need separate cables or other means of transmission (Radio, infrared) are installed.
  • a as in a development of the method according to claim 12 required processing of the first digital signal can be useful to reliably from this signal a pitch to be able to determine.
  • a determination of the fundamental frequency (pitch) of the first digital Signal is preferably carried out with the aid of a mathematical frequency filter (claim 13). This allows in contrast to the otherwise common method of Fast Fourier Transformation (FFT) a faster and more accurate Frequency determination from only one stop of the string.
  • FFT Fast Fourier Transformation
  • FIGs 1 to 4 is in different, partially enlarged Views an electric guitar 1 shown with a Device according to the invention is provided.
  • the electric guitar 1 can be roughly divided into the body 2, the bridge 3 and the head 4.

  • the Whirls 7 are mechanically connected to wings 8, so that by turning the wing 8 the end of the string on the vortex 7th or can be handled by this. This will the tension or length of the string changed and the guitar voted.
  • pick-guard 9 is a kind of cover plate and under the body 2 a space is created in which the electronics of Electric guitar 1 is arranged.
  • control chip associated with the device according to the invention arranged, which is indicated schematically in Fig. 2 with 10 is.
  • Fig. 2 it can also be seen that the head 4 of the electric guitar 1 on the mechanics of the wings 8, for example. Via a transmission, attacking servomotors 11 are arranged.
  • the Actuators belong to the device according to the invention and are in later to be described manner with the Control chip 10 connected for control. With the engines can alternatively to the manual over the wing 8 the vortex 7 is rotated and thus the tension of the strings 6a be adjusted to 6f.

Of the in Fig. 5 (d) enlarged illustrated rider insert is in the tab shown in Fig. 5 (a) into that shown in Fig. 5 (a). used recess shown right. Since the riders 15 and the riding inserts 16 in an electric guitar 1 regularly made of metal and thus made of a conductive material, need to make a short circuit between over the wires 14 electrically contacted strings to avoid the rider inserts 16, over which the strings 6a to 6f run against each other be isolated. For this purpose, those shown in Fig. 5 (a) Isolated with 21 designated areas.

It can be seen that all these units sit on a common board 22, the Further controls for controlling the servomotors 11 contains. About the metallic and thus conductive vertebrae 7 the strings are electric with corresponding tracks connected to the board 22.
