Would be cool to have the same video made for another high end bud... just to see how different companies use different strategies to solve the same issue.
THANK YOU SO MUCH for using Wh and providing nominal voltages! Much better info than what the clueless tech youtubers do providing just Ah/mAh without understanding that many devices use different voltages.
This genuinely gave me a whole new appreciation to my AirPods Pros. Its unbelievable how they were able to engineer these components into such a tiny product.
4:56 Ericsson is AWESOME for their work in this, and for giving it to the world, but this video really needed a hat tip to Hedy Lamarr. She invented the base ideas that all modern wireless systems rely on.
the vent explanation part were incorrect. Its not for resonant purpose, its there for 2 other purpose:
1. Prevent pressure buildup on your ear canal, when u insert them into your ear, due to eartips seal, u are compressing the air in your canal. Vent is there to release that pressure buildup. Otherwise the pressure either will push on either your eardrum or the speaker membrane. This also apply to controlling the pressure rise, when the speaker is doing long stroke movement during high amplitude low frequency sound (bass), they leak some of that bass pressure through the same port so it wont be overwhelming.
2. Speaker always move forward and backward in a sine wave. The vent is there to tune the properties of air flowing at the back of speaker membrane when its is moving backward. Mostly related to bass & low frequency response, and a bit of mid frequency.
The mesh explaining high frequency damping were spot on
Some of my videos get view spikes at bed time. I think it's listening to my boring ass ramble on about science for 16-30 minutes would put anyone to sleep 🤣
