This gives me a great idea for an energy-saving air conditioner. It's just a white noise generator chip, a power amp, and a speaker. It'll be super lightweight

- m463 6y agoDon't make it super lightweight - people won't think they're getting a good value if they buy it. I know this because long ago when we retired our old cheapie house phone, I took it apart and it had two lead weights in the base and handset. To have a similar "heft" compared to the old "ma bell" phones - which are made of actual durable materials - they removed lightness.
- paulmooreparks 6y agoThere's a practical reason for this. If you're accustomed to quickly lifting a hefty handset to your ear, then the first time you lift one that's significantly lighter you might bash yourself in the temple with the handset.

- sokoloff 6y agoMany old Bell-provided phone models also had metal weights inside.
- colanderman 6y ago(Assuming you are talking about a corded desk phone.) This is not the reason for the weights. Remove them from the base, and the phone ceases to stay put when you pick up the receiver (which is attached by a springy cord). Remove them from the receiver, and it is not heavy enough to keep the buttons on the hook depressed when hung up. (Source: I did exactly this in college, with exactly these results.)
