Philips sound heritage
Defining sound since the 1920s
Philips has pioneered advancements in audio for almost a century. Its researchers and
engineers have been responsible for bringing to the world numerous innovations that have
transformed the way we enjoy sound today. We are the pioneers that introduced the cassette
tape and portable cassette players, the compact disc and the first DAB digital radio.
The quest for the most authentic sound reproduction is one which has driven Philips since the
early days of radio. It all started in 1923 when Philips produced the Miniwatt radio valve.
Not satisfied with the radio valves that were available at the time, Philips produced a smaller
and more powerful version that needed far less electrical energy than the previous types.
This meant that the headphones which had been used by radio listeners, could now be
replaced by a loudspeaker, allowing families to enjoy sound together as a shared experience.
This was the first in a long line of innovations which would cement Philips’ position as one of
the most important players in audio history.
On the packaging of the Miniwatt radio valves was the iconic Philips shield logo with its
familiar waves and stars. Reflecting the role of sound within the company, the waves
symbolized radio waves and the stars represented the evening sky because at the time,
families would gather around the radio set in the evening to listen to news and entertainment.
Chapel Radio, 1931. This iconic radio set was nicknamed ‘The Little Chapel’.
