Loudspeaker with a gas adsorbing material and mobile device comprising a loudspeaker
A loudspeaker comprises an enclosure, at least one dynamic driver mounted in the enclosure, and at least one porous monolithic block comprises of a gas adsorbing material and a binder. The at least one porous monolithic block comprises a plurality of pores and is mounted within the enclosure.
1. A loudspeaker, comprising
an enclosure;
a dynamic driver mounted in the enclosure; and
a gas adsorbing material comprising porous particles and a binder, the particles being embedded in the binder and the gas adsorbing material mounted in the enclosure,
wherein the binder has a solid content of at least 30 percent by weight with regard to the total weight of the binder, and
wherein the gas adsorbing material forms a porous monolithic block, wherein the enclosure comprises a sub-enclosure, and the sub-enclosure is tightly filled with the gas adsorbing material which forms the porous monolithic block.
2. The loudspeaker of claim 1 , wherein the porous particles comprise a zeolite material.
3. The loudspeaker of claim 1 , wherein the porous particles have diameters of between about 2 μm and about 10 μm.
4. The loudspeaker of claim 1 , wherein the binder comprises at least one of a sodium carboxymethyl cellulose (CMC), a poly carbon acid, a bentonite, a Glycerin, an Ethylene-glycol and a methacrylic ester-acrylic ester copolymer.
5. The loudspeaker of claim 1 , wherein the binder comprises color-pigments.
6. The loudspeaker of claim 1 , wherein the porous particles comprise activated carbon.
7. A mobile device, comprising a loudspeaker according to claim 1 .
8. The loudspeaker of claim 1 , wherein the porous monolithic block comprises a plurality of first pores, and the plurality of first pores is formed by at least partially burning away the binder.
