Definitions

  • the present invention relates to a chromatic tuner for musical instruments, measuring the sound frequency produced by the instrument to be tuned, and displaying on a watch magnitudes characterizing the accuracy of the tuning, for example a wristwatch.
  • tuners In order to guarantee the correctness of the accuracy of the note independently of parameters altering the characteristics of a tuning fork, such as humidity and temperature, there are now electronic tuners, whose precision is finer to determine the frequency to associate with a note. These tuners contain on the one hand a microphone, converting the acoustic signal into an electrical signal, and a digital display device indicating the closest note and the accuracy of this note according to the detected acoustic signal and the signal. electric obtained.
  • tuners are calibrated on a fixed reference frequency, typically 440Hz; others can however be set to a neighboring frequency in order to adapt the sound of the instrument to particular acoustic conditions, such as the resonance properties of a building or a concert hall.
  • a disadvantage of portable electronic color tuners is that they are often relatively bulky, and the musician may forget them or lose them. Moreover, the digital display does not allow an intuitive reading of the indications provided, especially with respect to the accuracy of the note and the settings, both during the calibration operation and during the tuning itself. There is therefore a need for a chromatic tuner free of these limitations of the prior art.
  • An object of the present invention is to provide a chromatic tuner built into a portable device regularly available to musicians.
  • Another object of the present invention is to provide a chromatic tuner that allows easier reading and tuning of the frequencies obtained during tuning and the calibration frequency.
  • An advantage of the proposed solution is to allow the integration of a chromatic tuner in a watch, which allows musicians who need a tuner not to require instruments apart, and to have moreover this tool at hand almost continuously, as often as the watch that contains it is worn.
  • Another advantage of the proposed solution is to allow an easier reading of the results of the tuning with the needles of the watch on which the tuner is integrated.
  • the invention relates to a portable timepiece, typically a wristwatch, but for example also a pendant, a pocket watch, or any other portable time display device, with an integrated chromatic tuner that uses one or more several hands of the watch, usually dedicated to the display of the current time.
  • a timepiece therefore implicitly comprises a tuning mode distinct from the usual display mode hours, and wherein at least one of the needles is no longer used for this purpose.
  • the tuner comprises an electronic module for calculating the value of the sound frequencies emitted by the instrument to be tuned, and this value and the accuracy of this frequency with respect to notes of a range, for example the temperate range (do, do #, re, re #, mi, fa, fa #, sol, sol #, la, the #, if, for which the reference frequency is that of the at 440Hz) is displayed on the timepiece.
  • a range for example the temperate range (do, do #, re, re #, mi, fa, fa #, sol, sol #, la, the #, if, for which the reference frequency is that of the at 440Hz) is displayed on the timepiece.
  • the Anglo-Saxon notation for the temperate range corresponds to the notes “la” the value A, “if” the value B, “do” the value C, “re” the value D, “mi” the value E, “fa “the value F and” ground “the value G, as will be seen later on the display devices according to preferred embodiments of the invention.
  • Those skilled in the art will understand that it is conceivable to adapt the integrated tuner according to the invention to any type of range (natural, Pythagorean) and any tonic system.
  • the figure 1 illustrates the logical and functional elements of the electronic device 100 used in the context of a preferred embodiment of the invention.
  • the electronic device 100 firstly comprises an acoustic signal sensor 101, that is to say a microphone, which thus captures the acoustic waves of the external medium.
  • the received electroacoustic signal 10 is then transmitted to signal processing means 102, which transforms the electroacoustic signal 10 of the microphone into a pulse train 108, whose changes of state are caused by sign changes of the electroacoustic signal 10. microphone.
  • the pulse train 108 is therefore a binary signal, as opposed to the electroacoustic signal 10 which is an analog signal.
  • the signal processing means 102 consist of a filter 1021, which eliminates frequency components outside a determined signal bandwidth.
  • the signal 10 is then transmitted to an amplifier 1022 and a comparator 1023, such as for example a hysteresis comparator of the Schmitt Trigger type.
  • the pulse train 108 is transmitted to one of the input / output interfaces of a microcontroller 103, the whole of which is referenced by the number 115 for the sake of simplification.
  • the microcontroller 103 also has at least one output for delivering a supply current 106 of the signal processing means 102, a battery 107, a crystal oscillator 104, typically 32KHz and whose frequency is temperature compensated and periodically corrected by inhibition.
  • the microcontroller 103 also incorporates an RC oscillator 105 preferably of 4 MHz, which makes it possible to switch the clock of the processor 113 of the microcontroller 103 to a faster frequency when long calculations or rapid measurements have to be made, mainly during the activation of the tuner function.
  • the electronic device 100 further comprises user interface means 112, consisting for example of the preferred embodiments of the invention illustrated in particular by the Figures 3 and 4 , push buttons (referenced 16, 17, 18 in these figures).
  • user interface means 112 may however also consist of a crown rod (referenced for example on the Figures 5 to 7 by the number 9), or a touch screen, the latter variant is however not illustrated.
  • These user interface means 112 make it possible to interact with the user in particular to request a change of mode, to make adjustments and to validate these adjustments, as will be seen later. They interact on an input / output interface 115 of the microcontroller 103.
  • the electronic device 100 furthermore comprises, according to the preferred embodiment illustrated by the figure 1 , a motor module 114 composed of at least one bi-directional motor, associated with analog display means 111.
  • the analog display means 111 comprise at least one independent needle for displaying information on the received signal, the needle being either hours 3 or minutes 2, as will be seen on the Figures 3 to 7 which illustrate different display devices according to various embodiments of the invention.
  • Timepiece 1 with integrated chromatic tuner includes fully analog display systems, or hybrid with partially digital display. These embodiments are illustrated respectively by the Figures 3 and 4 which will be described later in this document.
  • the motor module 114 of the electronic device 100 acts independently on the two hands of the hours 3 and minutes 2 of the timepiece 1 to respectively give information on the note identified for the electroacoustic signal 10, and information on the accuracy with respect to this note.
  • the partially digital display system the note itself is displayed numerically, and not with a needle, for example on a liquid crystal display (LCD), which is a digital display means preferred.
  • LCD liquid crystal display
  • These digital display means are illustrated by reference 116 on the figure 4 in particular, which illustrates a preferred embodiment of the invention using this type of hybrid display.
  • These digital display means 116 can, however, also provide other information, such as the accuracy with respect to the note identified, and this information can also be corroborated by the presence of one or more hands on the dial 4 of the watch for a more intuitive reading.
  • the figure 2 illustrates the process of identifying notes and their correctness according to a preferred variant of the chromatic tuner of the invention.
  • the RC oscillator 105 is first calibrated in a step 201, because the frequency thereof varies over time as a function of the supply voltage and the temperature.
  • the calibration consists in counting the number of clock strokes of the oscillator RC 105 in a time window set by the period of a signal derived from the base clock 104 compensated in temperature. Calibration is carried out periodically, for example at seconds 3 and 33, in order to ensure stability of the frequency measurement of the acoustic signal. Oscillator calibration results in the correction factor to compensate for the frequencies determined during the note identification process.
  • Step 202 consists of the execution, by the microcontroller 103, not represented on the figure 2 of a process for measuring the binary signal 108 obtained at the output of the electroacoustic signal processing means 102, by counting the time between each rising edge of this signal 102 and successively memorizing each period of the signal 22 in the data memory 109
  • the periods acquired by the microcontroller form the series 231, which is then compared with a threshold, initially defined for example by the maximum value of the series 231, during step 2031.
  • the indices of the samples whose value is greater than threshold then form the reduced series 232, between which the duration between each element is calculated during step 2032.
  • These durations form the series 233, which is sorted during step 2033 in ascending order to form the series 234 .
  • the identification step 204 of the fundamental period of the electroacoustic signal 10 is then determined by searching for a periodic relation between the elements of the series 234.
  • the process starts from the smallest element of the series and then searches for multiples of this element while traversing the series in ascending order.
  • Each element of the series is divided by increasing whole numbers until approaching the smallest element. As soon as an element of the series approaches a multiple of this smallest element, then this element is considered to be the fundamental period of the signal; if on the other hand no multiple is found the process is reiterated with the next element of the series until finding a periodic relation in the series.
  • Step 2041 is to verify that a fundamental period has been identified, if so the result 24 is subject to the correction factor 25 to deliver the measured period 26, otherwise the threshold used in step 2031 is compared at half the value of the initial threshold, during step 2034 and then decremented by a predefined value, for example 10, at step 2035 to determine the new threshold to be used during a new iteration of the process of extraction of the fundamental frequency 203, which will thus repeat all the previous steps from 2031 with the new threshold.
  • the threshold should be less than half the initial threshold after step 2034, the process of identifying the fundamental frequency 203 is completed in step 206, and no frequency has been identified. The process of extracting the fundamental frequency 203 is therefore failing at step 206.
  • the measured period 26 is compared, at the step 207, with values of periods corresponding to musical notes, which are saved in the memory 109.
  • This table 21 values of musical notes makes it possible to determine, by comparison, the nearest note 11 in a discrete manner.
  • the display of the analysis results of the frequency of the acoustic signal is done at least partially in a discrete manner, since the displayed result must correspond to one of the periods saved in the table of the periods corresponding to musical notes .
  • the precision is indicated with respect to the frequency difference of one semitone, since the difference between the different identifiable notes is always a semitone. It therefore extends from a quarter of a ton to a quarter of a ton higher. This accuracy is preferably indicated by a percentage between -50 and + 50%.
  • the figure 3 illustrates a preferred embodiment of a timepiece 1 according to the invention, provided with only analog means for displaying information on the electroacoustic signal 10 received by the microphone of the integrated chromatic tuner.
  • the timepiece is here a wristwatch provided with a minute hand 2 and hours 3, which constitute the analog display means 111 mentioned above and illustrated on the figure 1 .
  • the watch is also provided with a bezel 5 and a dial 4, at the edge of which is a scale of notes 6, consisting of the notes Ab, A, Bb, B, C, Db, D, Eb, E, F, Gb and G which make up the 12 notes of the temperate scale, one for each semitone.
  • the display mode chosen according to this variant is chosen in flat, it is possible however also to consider the display of all the notes in hash (#), in which case the scale 6 would read G #, A, A #, B, C, C #, D, D #, E, F, F #, G. It can be seen that the scale of the notes 6 includes a blank flag 61, which indicates that no notes could be identified. This indicator 61 will thus be used when step 206, illustrated in FIG. figure 2 , will have been done; it can also be on a position of the dial 4, or the telescope 5, independent of the one used for the scale of the notes 6.
  • the scale of the notes 6 is arranged opposite the minute hand 2, at the periphery of the dial 4, on the lower half-dial corresponding to the hours 3 to 9.
  • the fact of using the largest needles 2 to determine the closest note 11 allows a quick and intuitive reading of the result, while the hour hand 3 is used here to give the frequency differential 12 between the note and the received electroacoustic signal.
  • the display device comprises an indicator of the correctness of the notes 7, constituted here by the graduations opposite which the hour hand 3 is positioned in the tuning mode of the watch.
  • the indicator makes it possible to display a tone ranging from a quarter-tone lower to a quarter-tone higher than the nearest note 11, and also allows an intuitive reading of this accuracy by matching the size of the hour hand.
  • the indication of the accuracy by the hour hand is preferably done on an arc whose angular value is preferably slightly less than 180 degrees, preferably around 120 degrees as illustrated in FIG. figure 3 .
  • the values of the percentages of maximum deviation at plus or minus 50% are indicated inside the arc of circle formed by the graduations which form the indicator 7. It is also possible to realize the indicator 7 in the form of a color scale varying around the green corresponding to a right note, and whose edges are red to indicate that the sound is false. It is also possible to realize this gradual indicator of color in the form of a circular arc whose one end is fine, and the other thick, in the manner of an eyebrow. In this case, the pointed end would correspond to a note too low, and the thick end of the eyebrow would correspond to a note too acute.
  • the embodiment of the figure 3 further illustrates a target zone 8 with respect to the frequency of the nearest note 11.
  • This target zone 8 indicated for example by a very thick graduation of a different color, for example green to indicate intuitively the accuracy, is preferably centered with respect to the dial 4 and indicates that the frequency of the acoustic signal is in a range values sufficiently close to the desired note, for example less than 3%, to no longer justify an additional agreement.
  • This target zone is preferably in the middle of the graduations of the indicator 7 of the accuracy of the note, but could also be outside the arc formed by the graduations.
  • the embodiment of the figure 3 also shows three push buttons: the first 16 being used to increment values and the second to decrement values, such as for example calibration values 14, as will be seen in more detail using the figure 6 .
  • the last push button 18 shown on the figure 3 is preferably used for the change of mode, in particular for entering the tuning mode which can for example be activated by a prolonged pressure of more than two seconds, in order to avoid any untimely tripping of the calibration mode, of a part because it uses the needles and therefore does not allow to view the time simultaneously, and secondly because this mode is energy-hungry because it must feed the microphone and the microcontroller 103 must perform many calculations It makes a lot of use of its basic clock or central processing unit (CPU) 104.
  • This button can also be used preferably to validate settings, such as the values used for calibration. We can imagine that the entry in the tuning mode can be validated by the positioning of the two hands minutes and hours, superimposed at noon on the dial 4 of the watch.
  • the figure 4 illustrates a dial of a timepiece 1 according to the invention, for example a wristwatch, which is provided with hybrid display means, that is to say both digital and analog.
  • the analog display means 111 are always constituted by the hands of the hours 2 and minutes 3, but this time these analog means 111 are only used to indicate the accuracy of the notes, it is that is to say, the frequency difference 12 relative to the nearest note, while the height of the nearest note 11 is displayed numerically on an LCD screen, which constitutes the digital display means 116.
  • These means digital display 116 indicate, according to the figure 4 , that the note Eb has been identified; the needles 2 and 3 are superimposed and point to the value -44% of the graduations of an indicator 7 located in the upper half of the dial 4.

  • the additional information indicated by the digital display means 116 could be the pitch, that is to say the reference frequency used for the frequency measurement of the notes, when this can be set on a frequency other than the usual LA frequency at 440Hz.
