En bleu, les valeurs entrées en base de données. En blanc, les valeurs calculées avec les formule ci-dessous.
En rouge, une erreur pratiquement certaine, une confusion entre impédance et résistance au courant continu de la bobine du HP.

  • Qts=Qms*Qes/(Qms+Qes)
  • Mms=(C*Sd/(2*Pi*Fs))2*Ro/Vas
  • Rd=racine(Sd/pi)
  • Mmrf=(8*Ro*Rd3)/3
  • Mmd=Mms-Mmrf
  • Rms=2*Pi*Fs*Mms/Qms
  • B.L=(2*Pi*Fs*Mms*Re/Qes)1/2
  • Rend=(4*Pi2/C3)*(Fs3*Vas/Qes)*100
  • Sens=10*LOG(Rend/100)+112.1+10*LOG(8/Re) en dB/2.83V/m
  • Sens=10*LOG(Rend/100)+112.1 en dB/W/m
  • Xmax et Puissance sont liés : Si la puissance calculée est environ 4 fois plus grande que celle indiquée par le fabricant, c'est qu'il y a un Xmax 2 fois trop grand.

En cas de différence entre les données calculées et celles indiquées par le fabricant du HP, vérifiez si les valeurs en bleu sont identiques à celles du fabricant.
Si c'est le cas, dites vous bien qu'un calcul informatique ne peut pas être a la fois juste pour un HP et faux pour un autre.
Le calcul est soit juste pour tous, soit faux pour tous.
J'ai vérifié soigneusement...

Un grand-père facétieux disait à ses petits enfants que le grand truc blanc tout en haut du Puy-de-Dôme était un thermomètre géant : Quand il deviendra tout rouge il faudra vite se sauver, parce que le volcan va se réveiller !!!

Malgré les apparences, ce site internet n'est que celui d'un amateur passionné auvergnat.
"Amateur" doit être compris dans le sens "non professionnel", dans l'aspect financier de l'approche : Je ne vis pas des revenus de cette passion.
"Amateur" doit être compris dans le sens ou rien ne m'oblige à vous répondre, si vous êtes désagréable. C'est rare, mais le cas arrive de temps en temps.

Il y a un savoir-vivre élémentaire qui consiste à demander l'autorisation avant de reprendre tout ou partie de ce qui est écrit dans ce chapitre.
Je vous donnerai l'accord, demandez-le simplement pour être en règle. Sont exclues les demandes extravagantes, les demandes de copie de ma base de données haut-parleurs.
