Definitions

  • the invention relates to acoustic devices and more particularly, but not exclusively, to loudspeakers incorporating resonant multi-mode panel acoustic radiators, e.g. of the kind described in our International application O97/09842. Loudspeakers as described in O97/09842 have become known as distributed mode (DM) loudspeakers.
  • DM distributed mode
  • the panel is placed in coupled contact with this active wave surface and the surface wave excitation of the panel excites the fluid. Conversely the natural wave properties of the fluid interact with the panel, so modifying its behaviour. This is a complex coupled system with new acoustic properties in the field.
  • Figure 8 shows a DML panel system
  • Figure 21 shows a microphone set up for measuring the internal pressure in the enclosure
  • a panel in this form of deployment can provide a very useful bandwidth with quite a small enclosure volume with respect to the diaphragm size, as compared with piston speakers.
  • the mechanisms responsible for the minimal interaction of this boundary with the distributed mode action are examined and it is further shown that in general a simple passive equalisation network may be all that is required to produce a flat power response. It is also demonstrated that in such a manifestation, a DML can produce a near-ideal hemispherical directivity pattern over its working frequency range into a 2Pi space.
  • FIG. 7 The system under analysis is shown schematically in Figure 7.
  • the front side of the panel radiates into free space, whilst the other side is loaded with an enclosure.
  • This coupled system may be treated as a network of velocities and pressures are shown in the block diagram of Figure 8.
  • the components are, from left to right; the electromechanical driving section, the modal system of the panel, and the acoustical systems.
  • the normal velocity of the bending-wave field across a vibrating panel is responsible for its acoustic radiation.
  • This radiation leads to a reacting force which modifies the panel vibration.
  • the radiation impedance which is the reacting element, is normally insignificant as compared with the mechanical impedance of the panel.
  • the effect of acoustic impedance due to its rear radiation is no longer small, and in fact it will modify and add to the scale of the modality of the panel.
  • ⁇ P ⁇ ( X , y ) is the value of the i th plate eigen-function at the position where the velocity is observed.
  • ⁇ p ⁇ ( XO ,yo) is the eigen-function at the position where the driving force F p ⁇ ⁇ J(a) is applied to the panel.
  • the driving force includes the transfer functions of the electromechanical components associated with the driving actuator at (x 0 ,y 0 ), as for example exciters, suspensions, etc. Since the driving force depends on the panel velocity at the driving point, a similar feedback situation as with the mechanoacoustical coupling exists at the drive point (s), albeit the effect is quite small in practice. 13
  • the indices, k and 1 are the enclosure cross-mode numbers in x and y direction, where Ldx and Ld y are enclosure dimensions in this plane.
  • Ao is the area of the panel and
  • Panels were mounted onto a back enclosure with adjustable depth using a soft polyurethane foam for suspension and acoustic seal.
  • the enclosure depth was made adjustable on 16,28,40 and 53mm for set 'A' and on 20,50,95 and 130mm for set 'B' panels.
  • Various measurements were carried out at different enclosure depths for every test case and result documented.
  • Figure 25b shows the same panel as in Figure 25a but this time loaded with two identical enclosures, one on each side of the panel, with the same cross-section as the panel and a depth of 24mm.
  • a double enclosure was designed and used in order to exclude the radiation impedance of free field on one side of the panel and make the experiment independent of the free field radiation impedance. It is important to note that this laboratory set-up was used for theory verification only.

Abstract

Selon un aspect, l'invention concerne un dispositif acoustique, notamment une enceinte, comportant un panneau de rayonnement acoustique multimode résonant actif sur des faces opposées, un excitateur de vibrations disposé de façon à appliquer une vibration d'onde de flexion au panneau résonant de façon à produire une sortie acoustique, un organe définissant une cavité qui renferme au moins une partie d'une face du panneau et qui est disposé de façon à recevoir le rayonnement acoustique de ladite partie d'une face du panneau. Cette cavité modifie le comportement modal du panneau. Selon un autre aspect, l'invention concerne un procédé permettant de modifier le comportement modal d'un dispositif acoustique à panneau résonant. Ce procédé consiste à amener le panneau résonant à proximité immédiate d'une surface limite, de façon à définir une cavité de résonance entre le panneau et la surface.
