Abstract
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 an adsorbent element in the form of a self-supporting monolith-like element with a porous reticulated structure. The adsorbent element includes adsorbent material which comprises microporous organic polymer (MOP) 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.
Claims20
Apparatus for providing and/or receiving audible sound, comprising:
- a housing that provides at least one cavity region;
- a vibratable element in or proximate to the at least one cavity region;
- and
- an active region comprising an adsorbent element in the form of a self-supporting monolith-like element with a porous reticulated structure
- wherein the adsorbent element is confined from movement within the active region, wherein the adsorbent element comprises an adsorbent material comprising a microporous organic polymer (MOP) material.
A mobile electronic device, comprising:
- a case body;
- and
- at least one speaker unit or microphone unit in the case body;
- wherein
- each speaker unit or microphone unit comprises a housing defining at least one cavity region, a vibratable element in or proximate to the at least one cavity region and an active region that comprises an adsorbent element in the form of a self-supporting monolith-like element with a porous reticulated structure, wherein the adsorbent element is confined from movement within the active region, and wherein the adsorbent element includes an adsorbent material comprising a microporous organic polymer (MOP) material.
A speaker system, comprising:
- a speaker unit;
- and
- a cabinet forming a chamber at a back region or side region of the speaker unit largely filled with an adsorbent element in the form of a self-supporting monolith-like element with a porous reticulated structure, wherein the adsorbent element is confined from movement within the chamber, and wherein the adsorbent element includes adsorbent material which comprises microporous organic polymer (MOP) material.
A microphone system, comprising:
- at least one transducer element for converting sound to an electrical signal;
- optionally a preamplifier that receives an output from the at least one transducer element;
- a housing or cabinet at a back region or side region of the transducer element;
- and
- an active region comprising an adsorbent element in the form of a self-supporting monolith-like element with a porous reticulated structure, wherein the adsorbent element is confined from movement within the active region, and wherein the adsorbent element comprises an adsorbent material comprising a microporous organic polymer (MOP) material.
