The First Music
Playing Devices: Jan
1,1887
The original music playing device
was the Phonograph. It was created
by The phonograph was invented by
Thomas Edison. Original phonograph
what used mainly as a recording
device. Thomas Edison used for
showing it to people and how and
explained how it worked. This device
was originally made and many
modifications were made to the
cylinder which emits the sound. The
cylinder was switched between
different types of metals. Materials_
Iterchangeable needle stylus, wax
coated cylinder, tinfoil cylinder,
cardboard cylinder and a wooden
box. Improvments_ The stylus and
cylinder was changed to make a
better sound disk with music where
later added forming the gramophone
Gramophone
Jan1,1887
Although the phonograph was
accredited as the first music
playing device the
gramophone and the
phonograph were introduced
on the same date to the
public. The gramophone was
invented by Emile Berliner.
Who was the first inventor to
stop recording on cylinders
and recorded on disc. This
was a breakthrough
improvement because it make
the carrying of music easier.
The disk was made of many
materials such as rubber,
mineral filters(grinded up
rock), slate, and cotton
fibers. A gramophone is also
known as a turntable, record
player, and record table.
Cassette Player and
Cassette
Jan 1, 1965
The cassette player and tapes
was invented by Phillips
Cooperation in 1963. They
were made available to the
public in 1965. The original
materials used were metal
and plastic. The early cassette
player were built with and
external microphone. A flaw
of the device is that the speed
at which the tape played was
set at the factory. The user
could not adjust how fast or
slow the tape played so if it
went to fast you were out of
luck. An improvement was
that Sony tried to strengthen
the film inside of the tapes.
They tired to do this so that
they would last longer.
The Sony Walkman
Jan 1, 1978
The Sony walkman was
created by Masaru Ibuka
and Akio Morita in 1979.
This was a breakthrough in
the music business because
it allowed people to carry
there music in a light weight
and can be taken virtually
anywhere. One of the
interesting improvements
that were made was it had
two head phone jacks so
two people could listen to
the same thing at the same
time. Eventually the
Walkman was developed
intro one of the first CD
players known as the Disc
Man introduced in 1984.
MP3 Jan 1, 1998
In 1998 the first MP3
players were distributed to
the public. They where
initially invented by the
Fraunhofer-Gesellshaft
company in Germany. The
original materials were a
digital signal processer,
audio and data interface,
high resolution interface
cards, high frequency
resolution filter bank, nonuniform quantization, and
Huffman coding. They
improved it by adding a
Audio codec called a
adaptive spectral perceptual
entropy coding so that it
can hold more songs.
IPod music players
Introduced inNovember 20, 2001
The IPods were first
introduced on November
20, 2001. Invented by Steve
Jobs of Apple the original
IPods were unbelievably
bulky. But over the years
Apple has made vast
improvements to them. The
original materials were a
plastic case, various metals,
and large circuit board. The
Ipod touch however is
completely different form
the orignal ipods. They have
a protective plastic cover
with another metal cover so
it wont break easily.
