Abstract
An apparatus includes an acoustic chamber, an agglomeration of acoustically adsorbing members in the acoustic chamber and suitably located substantially on or in a non-conductive support that comprises a substantially acoustically transparent material, and a transducer configured to generate acoustic waves which enter the acoustic chamber. Each acoustically adsorbing member is separated from neighboring members.
Claims17
An apparatus comprising:
- an acoustic chamber configured to be shared by at least an antenna portion and an audio transducer in an attempt to meet both acoustic requirements and radio frequency requirements;
- an agglomeration of acoustically adsorbing members in the acoustic chamber arranged to enable an antenna functionality by the antenna portion, the audio transducer being operably connected to the acoustic chamber, the agglomeration of acoustically adsorbing members being suitably located substantially on or in a substrate such that at least one acoustically adsorbing member is affixed at least to one surface of the substrate, wherein each acoustically adsorbing member is separated from neighbouring acoustically adsorbing members by an air gap or a non-conductive support material;
- and
- wherein the audio transducer is acoustically connected to the acoustic chamber and configured to generate acoustic waves which enter the acoustic chamber upon driving the audio transducer;
- wherein each acoustically adsorbing member has at least one dimension less than associated radio frequency wavelength of a radio frequency signal to be transmitted and/or received by the antenna portion.

A method comprising:
- outputting an audio signal from a processor to which a memory is connected;
- and
- receiving the audio signal in an audio transducer acoustically connected to an acoustic chamber and configured to generate acoustic waves which enter the acoustic chamber upon driving the audio transducer, the acoustic chamber being configured to be shared by at least an antenna portion and the audio transducer in an attempt to meet both acoustic requirements and radio frequency requirements and having an agglomeration of acoustically adsorbing members arranged to enable an antenna functionality by the antenna portion, the audio transducer being operably connected to the acoustic chamber, the agglomeration of acoustically adsorbing members being suitably located substantially on or in a substrate such that at least one acoustically adsorbing member is affixed to one surface of the substrate, wherein each acoustically adsorbing member is separated from neighbouring acoustically adsorbing members by an air gap or a non-conductive support material;
- wherein each acoustically adsorbing member in an acoustic transducer system has dimensions less than an associated radio frequency wavelength of a radio frequency signal to be transmitted and/or received by the antenna portion.
