headphones invention

Headphones were originated from a
telephone receiver earpiece, and were the only way to listen to electrical
audio before amplifiers were developed. The first truly successful set was
developed in 1910 by Nathaniel Baldwin, who made them by hand in his kitchen and sold them
to the United States Navy.

What is interesting
about this is what this man could do with so little technology on his side, how
much ambition and creativeness you must have in order to accomplish so much to
the birth of the headphones which nowadays are so irreplaceable in our lives.

In 1958, John C. Koss, an audiophile and jazz musician from Milwaukee, produced the first stereo headphones. When previously,
headphones were used only by the US navy, telephone and radio operators, and
individuals in similar industries.

This allowed smaller ear
bud type earpieces, which plugged into the user’s ear canal, were first
developed for hearing aids. They became widely used with transistor radios, which commercially appeared in 1954 with the
introduction of the Regency TR-1. The most popular audio device in history, the
transistor radio changed listening habits, allowing people to listen to radio
anywhere.  (wikipedia.org, 2018)

The ear bud uses
either a moving iron driver or a piezoelectric crystal to produce sound. The 3.5 mm radio
and phone connector, which is the most commonly used in portable
application today, has been used at least since the Sony EFM-117J transistor
radio, which was released in 1964.Its popularity was reinforced with its use on
the Walkman portable tape player in 1979.

All of these is
important for us to know because only in this way we can understand how this
complex devices work and were developed through time, it surely wasn’t easy for
the ones that developed this device in the early days so it is important to
acknowledge them and recognize their work.

I choose this topic
because without this headphones personally my life would be different and I
think most of people’s lives would be different as well, it helps me relax to
be able to listen to music whenever I want and overall helps me hear any type
of information I would like to on a daily basis and I’m sure this is the case
of most of us.
