Definitions
- the invention relates to a device comprising a sound signal generator. comprising an input member and a sound reproduction member.
- the invention also relates to a method for forming a call signal.
- the invention finds important applications in particular as regards the case where the audible signal, replacing the traditional bell, is the call signal for mobile radiotelephones.
- the present invention provides a device of the kind mentioned in the preamble which gives a great initiative on the development of this call sign.
- such a device is remarkable in that it is provided with a member harmonization to transform into polyphonic melody formed by notes accompanying a monodic melody captured by means of said input member, and a connection member for applying said polyphonic melody to the reproduction device sound.
- the device of the invention bears the reference 1.
- This device in the part of the example described, is a mobile radiotelephone for a cellular network.
- These measures comprises a transmission-reception part 5 for transmitting and receiving waves by means of a antenna 7, a screen 11, a keyboard 10 and also an audio-frequency circuit 15 for processing the audio signals that come from a microphone 17 and the signals to apply to a speaker 20.
- All the treatments are implemented on this device under the control of a set with processor 30 cooperating with a memory assembly 35 containing, inter alia, the instructions for these treatments.
- the various information provided and accepted by these different elements pass through a common BUSAD data line.
- the loudspeaker 20 When the user receives an incoming call which concerns him, the loudspeaker 20 emits a call signal that the user would like as pleasant as possible or that seems to him the most reflect his personality.
- the invention proposes that the user determines the call melody himself. by singing or whistling into the microphone 17.
- the device includes means for forming an accompaniment to this melody.
- Figure 2 shows a so-called monodic melody that the user hummed on his microphone 20. From this monodic melody, accompaniment will be established in using the following operations carried out in particular by means of the cooperating processor 30 with memory set 35.
- FIG. 3 shows a flowchart for explaining the operation of the invention.
- the box K1 indicates the step of entering the melody, obtained by means, for example of the microphone 17.
- Each of the notes entered is analyzed and the frequency of each of these notes is determined (box K3).
- box K5 it is examined whether the spacing of the notes entered are multiples of the intervals of the temperate range ( 12 2 ) Notes close to these temperate degrees are assigned an accompaniment chord, those too far away are not. Close notes are assigned a Tp flag, this is indicated in box K5.
- Box K7 indicates the establishment of each of the chords for the notes "Tp" according to a process detailed in FIG. 4.
- box K10 which can be an optional step, notes of agreement are added between two successive chords.
- the step indicated in box K12 is a step of recording the melody rendered polyphonic in the memory assembly 35.
- chords For each of these degrees there are several possible predefined chords (box K22).
- two chords have been assigned corresponding to states S1 and S2.
- possible chords are do-mi-sol and sol-do-mi, in considering the tone of C major.
- coefficients "p" indicated in bold on the states involved in the example of melody monodic shown in figure 2.
- Figure 6 also gives "p" values of transitions between agreements. These values are also given for this same example of melody.
- Figure 7 shows the possible paths to develop the accompaniment in order to provide a polyphonic melody.
- Figure 8 shows the polyphonic melody thus obtained.
- the melody thus recorded is available to be applied to speaker 20.
- a connection between the memory 35 where it is recorded will be established with the audio circuit frequency 15, via the BUSAD line, so that the call signal can be heard.
- Figure 9 shows a flowchart defining a variant of box K20 for set the tone. It is based on the following considerations.
- a histogram of the melody notes is established (box K50). That is to say that we have a statistic of the number of do (nb (do)) of do # nb (do #) etc ... We can thus define a histogram vector of the notes of the melody for each degree.
- the final choice of the tone depends on the values of true () obtained. As an example, we can take the tone that maximizes true () (box K56).
- melody can also be entered using the keyboard 10 of the device, keys being assigned to musical notes.

Abstract
Description
- saisie d'une mélodie monodique formée de notes
- affectation d'un accord pour une grande partie de ces notes en vue de former une mélodie polyphonique,
- enregistrement de cette mélodie polyphonique,
- application de cette mélodie polyphonique à un organe de restitution sonore pour effectuer un appel.
où nb(x) désigne le nombre de notes "x" contenu dans la mélodie.
les notes "piliers" de la tonalité sont les degrés 1, 4 et 5 (tonique, sous-dominante, dominante). Les degrés 2, 3, 6 et 7 sont plutôt moins fréquents, surtout pour des mélodies simples, qu'un utilisateur courant pourra entrer.
De ce fait, on définit deux vecteurs "masques", un en Majeur et un en mineur. Ce masque pondère l'histogramme des notes de la mélodie.
Pour le masque majeur, on peut prendre le vecteur
Ensuite, on calcule un "score de vraisemblance" pour la tonalité Do Majeur et Do mineur par
Ensuite, le "score de vraisemblance" est calculé pour les 22 autres tonalités possibles (11 majeures de do#Majeur à si Majeur + 11 mineures de do#mineur à si mineur) par simple translation des valeurs de l'histogramme (case K(54).
Par exemple H(ré) = [ nb(re), nb(re#), nb(mi), nb(fa), nb(fa#), nb(sol), nb(sol#), nb(la), nb(la#), nb(si), nb(do), nb(do#),]
et
A titre d'exemple, on peut prendre la tonalité qui maximise vrais( ) (case K56).
