Abstract
Official abstract text for this publication.
A loudspeaker, comprising an enclosure; at least one dynamic driver mounted in the enclosure; and a porous sound adsorber material disposed within the enclosure, the sound adsorber material at least comprising a Metallic Organic Framework material.
First claim
Opening claim text (preview).
What is claimed is: 1. A loudspeaker, comprising an enclosure; at least one dynamic driver mounted in the enclosure; and a porous sound adsorber material disposed within the enclosure, the sound adsorber material at least comprising a Metallic Organic Framework material, wherein the Metallic Organic Framework material comprises individual Metallic Organic Framework particles, the sound adsorber material comprises a binder adhering the individual Metallic Organic Framework particles together, the sound adsorber material constitutes a granulate comprising grains, each grain having a plurality of the Metallic Organic Framework particles adhered together with the binder. 2. The loudspeaker of claim 1 , the grains having a size between 50 μm-1.33 mm. 3. The loudspeaker of claim 1 , the adsorber material comprising pores having a diameter between 0.7 μm to 30 μm. 4. The loudspeaker of claim 1 , the particles of the Metallic Organic Framework material having diameters between 2 μm-10 μm. 5. The loudspeaker of claim 1 , wherein the porous sound adsorber material has a slit back volume, the porous sound adsorber material is filled directly into the slit back volume, wherein a size of slits is smaller than a diameter of the granulate.
