Besides detailed build
instructions and videos of
audio tests, Matthew’s also
shared details about the
physics of the sound domesSOUND DOME
atthew is fascinated by umbrellas.
On the lookout for ways to use them
to their full creative potential, he came
across the umbrelAudio unidirectional
speaker, and decided to create one
of his own using an umbrella. Instead of a plastic
bowl, Matthew uses a dome umbrella as a parabolic
unidirectional speaker that’s able to direct audio,
such as music, to one
specific location. You’ll
need several bits and
bobs to replicate his
build. The laborious
process involves creating
and attaching a mount
for a battery-powered
speaker, and running wires from the speaker to your
audio source. Matthew used a couple of hooks
to hang his umbrella speaker on
his dorm’s light bowl fixture to get
the true Cone of Silence feel. He
suggests you place the speaker
at least 5” from the top of the
umbrella to maximise the sound
space. The original hack is
almost a decade old, and
Matthew suggests using
Bluetooth speakers now
to save a lot of hassles
soldering wires and keep
the build clean, adding that
he’ll now “probably go with a
programmable field sound array
to disperse the sound across the
entire umbrella, as opposed to just
one location.”LENSM
