Abstract
A mobile device including a source for emitting electromagnetic radiation, an enclosure having a side wall, and a detector for detecting electromagnetic radiation emitted by the source is described. At least a portion of the sidewall is adapted to transmit electromagnetic radiation from the source. The source and detector are positioned inside the enclosure. The detector is spaced from the source, and is arranged to detect electromagnetic radiation from the source that is reflected from an object outside the enclosure and passes through the portion of the side wall.
Claims20
A mobile device comprising:
- a source for emitting electromagnetic radiation;
- a transducer;
- an enclosure having a side wall, at least a portion of the side wall being both sound permeable and adapted to transmit electromagnetic radiation from the source;
- and
- a detector for detecting electromagnetic radiation emitted by the source in use, the source, detector and transducer being positioned inside the enclosure, wherein the transducer is positioned between the source and the detector;
- wherein the detector is spaced from the source, and is arranged to detect electromagnetic radiation from the source that is reflected from an object outside the enclosure and passes through the portion of the side wall.
A mobile device comprising:
- an acoustic enclosure having a wall portion that is both sound permeable and adapted to transmit electromagnetic radiation,
- a proximity sensor, and an acoustic transducer positioned within the acoustic enclosure between a source for emitting electromagnetic radiation and a detector for detecting electromagnetic radiation emitted by the source, the proximity sensor being arranged to detect electromagnetic radiation that passes through the wall portion.
