A study is made of the sound field created by a loudspeaker cone, with or without a rigid planar baffle and radiating from one or two faces.

Using Helmholtz-Huygens's integral equation, a point-value of radiation impedance enables the sound pressure to be approximately deduced from the supposedly known value of the speed of the vibrating surface.

Theoretical and experimental results are compared when the speed of the diaphragm is approximately constant.

Sommaire

On calcule le champ sonore crée par un haut-parleur à diaphragme conique, placé ou non dans un écran rigide de dimensions finies et rayonnant par ses deux faces ou par une seule d'entre elles.

L'introduction d'une impédance ponctuelle de rayonnement permet d'exprimer de manièrc approchée, à partir de l'équation intégrale d'Helmholtz-Huygens, la pression sonore en fonction de la vitesse ponctuelle supposée connue de la surface vibrante.

Résultats théoriques et expérimentaux sont comparés dans le cas où le diaphragme vibre approximativement en piston.

Zusammenfassung

Es wird das von einem Lautsprecher mit konischer Membran erzeugte Schallfeld berechnet, der frei ist oder in einem schallharten Schirm mit endlichen Abmessungen eingesetzt ist und der entweder von beiden Seiten oder nur von einer Seite strahlt.

Ausgehend von der Helmholtz-Huygens'schen Integralgleichung, kann man durch Einführung einer punktuellen Strahlungsimpedanz näherungsweise den Schalldruck als Funktion der als bekannt angenommenen Schnelle der schwingenden Fläche ausdrücken.

Theoretische und experimentelle Ergebnisse werden miteinander verglichen für den Fall einer etwa kolbenartig schwingenden Membran.
