Rocking on Eggshells
Scrambled, poached, or sunny side up? How about
in stereo? Michihiko Goto (who goes by Gomhi)
of Hamamatsu City in Shizuoka, Japan, carved
these mini speakers from the classic breakfast

Vol. 1, showing what appeared to be an electronic
egg sounding off, Goto, 33, decided to make a set
of his very own.
First, he emptied store-bought hen eggs by drilling a small hole in the shells and letting the goo
pour out. Next, he cut the shells with a mini router
and chiseled the speaker drivers’ plastic frames
with a nipper before nestling one driver — a HiVi
B1S transducer that converts an electrical signal
to sound — into each egg.
To ensure the driver arms didn’t break their housings, he lined the back of each shell with cotton and
used acrylic foam tape on the front. Each speaker
rests atop an air-dry clay foot.
“Eggshell is harder than I expected,” Goto says.
“For me, to mark the cutting line precisely on the
eggshell is the most difficult thing. I heard there is
a good tool known as Egg Marker.”
He wasn’t in it for the chicks. Although Goto
describes the sound that comes from the speakers
as “narrow,” he says, “Surprisingly, my wife almost
took the sound from eggshell speakers for our
favorite in everyday use.”
The music that sounds best through the eggs?
According to Goto, it’s Water Strings by Masako
Toda, because of the female vocal and acoustic
Since he made the eggshell model, Goto has
considered turning his wife’s pottery, pieces of
bamboo, even calabash gourds into speakers. But
his wife specializes in urushi, Japanese lacquer
used for traditional arts and crafts, and Goto says
that’ll definitely be his next medium.
