loudspeakers and headphones use the variations in
alternating current
to produce
sound waves
as the
current
travels through the
coil
it experiences a
force
due to the
magnetic field
. this makes the
speaker cone
move
because the
current
is
alternating
the
direction
of the
force alternates
and the
speaker cone oscillates
increasing the electrical power will produce a
larger force
so the
cone
will
oscillate
with a
higher amplitude
and produce
louder sound waves
the
frequency
of the sound produced mathes the
freuquency
of the
alternating current
the size of the speaker affects how
quickly
or
slowly
it can
oscillate
and how
big
they will be
a
larger
cone is better for
low
pitched sounds and a
small
cone is better for
high
pitched sounds
the motor effect is used in
motors
and
speakr
to convert
electrical
energy into
kinetic
and
sound
energy
