I’ve often heard about the old His Masters Voice record players, but this is the first time that I’ve seen one.
You may look scornfully at this primitive record player. When I was an electronic designer, I had a notice above my bench saying “All designers stand on the shoulders of those who have gone before.” iPods could not have been designed without all the sound players that had gone before.
You may think that iPods are all electronic, but they’re not. Speakers create sound by vibrating the air to make your ear drums vibrate for the right sounds. Earphones are just miniature speakers. They are a lot smaller than the trumpet used by HMV, but they still work the same way – making the air between the speaker and your ears vibrate the right way.
Designs become more robust as time passes. I hate to think what would happen if you dropped the HMV record player, but the iPod would probably keep on working after you dropped it.
You may dismiss the HMV record player as “primitive” but could you make one? And as for advertising – could you come up with a better idea than the picture of a dog listening to His Master’s Voice?
