Abstract
There is provided a loudspeaker apparatus having: a first unit arranged to propagate sound in a first frequency range; and a second unit arranged to propagate sound in a second frequency range that is higher than the first frequency range. The first unit includes a sound-radiating member and the second unit is mounted to the sound-radiating member of the first unit. The first unit and the second unit are driven by separate audio channels and/or the sound-radiating member of the first unit is planar.

A loudspeaker apparatus comprising:
- a first sound-radiating unit arranged to propagate sound in a first frequency range, the first sound-radiating unit comprising a sound-radiating member;
- and
- a plurality of second sound-radiating units arranged to propagate sound in a second frequency range that is higher than the first frequency range, each second sound-radiating unit comprising a sound-radiating member;
- wherein each second sound-radiating unit is mounted on the sound-radiating member of the first sound-radiating unit;
- wherein the sound-radiating members of the second units cover at least 80% of the sound-radiating member of the first unit;
- and
- wherein the first sound-radiating unit and the plurality of second sound-radiating units are driven by separate audio channels and/or the sound-radiating member of the first sound-radiating unit is planar.
A loudspeaker system comprising a plurality of loudspeaker apparatuses arranged in an array, each apparatus comprising:
- a first sound-radiating unit arranged to propagate sound in a first frequency range, the first sound-radiating unit comprising a sound-radiating member;
- and
- a plurality of second sound-radiating units arranged to propagate sound in a second frequency range that is higher than the first frequency range, each second sound-radiating unit comprising a sound-radiating member;
- wherein each second sound-radiating unit is mounted on the sound-radiating member of the first sound-radiating unit;
- and
- wherein the sound-radiating members of the second units cover at least 80% of the sound-radiating member of the first unit.
A kit of parts for a loudspeaker apparatus, comprising:
- a first sound-radiating unit arranged to propagate sound in a first frequency range, the first sound-radiating unit comprising a sound-radiating member;
- and
- a plurality of second sound-radiating units arranged to propagate sound in a second frequency range that is higher than the first frequency range, each second sound-radiating unit comprising a sound-radiating member;
- wherein each second sound-radiating unit is adapted to be mounted on the sound-radiating member of the first sound-radiating unit;
- wherein the sound-radiating members of the second units are arranged to cover at least 80% of the sound-radiating member of the first unit;
- and
- wherein the first sound-radiating unit and the second sound-radiating units are adapted to be driven by separate audio channels and/or the sound-radiating member of the first sound-radiating unit is planar.
