Abstract
(EN)
The present invention relates to a method and apparatus for providing and/or receiving audible sound. In particular, the invention relates to apparatus, such as a micro speaker, which includes an active region which comprises a particulate adsorbent material comprising i) microporous organic polymer (MOP) material,and/or ii) metal organic framework (MOF) material treated with a hydrophobic coating or a membrane. The particulate adsorbent material is either in the form of loose or semi-loose granules, or it is supported by or impregnated into a woven, knitted or non-woven felt material. The apparatus of the present invention is suitable for use in an electronic device, for example a mobile or portable electronic device, to provide improved audible sound.

La présente invention concerne un procédé et un dispositif de fourniture et de réception de son audible. En particulier, l'invention concerne un appareil, tel qu'un micro-haut-parleur, qui comporte une région active qui comprend un matériau adsorbant particulaire constitué i) de matériau polymère organique microporeux (MOP), et/ou ii) d'un matériau de type réseau métallo-organique (MOF) traité avec une membrane ou un revêtement hydrophobe. Le matériau adsorbant particulaire se présente sous la forme de granulés libres ou semi-libres, ou est supporté par un matériau de feutre tissé, tricoté ou non tissé, ou imprègne ce matériau. L'appareil de la présente invention est apte à être utilisé dans un dispositif électronique, par exemple un dispositif électronique mobile ou portable, pour fournir un son audible amélioré.
