We had a 1st gen Echo in our master bathroom for listening to music in the morning ru-vid.comUgkxABghAEkaIDGZfHRBH3D3rBrlraNmnC71 and while in the shower. I didn't realize how tinny and awful the sound output on the original Echo was until we replaced it with the Studio. It was a sonic upgrade far beyond what I was expecting. Just wow. I love it because it's like having speakers IN the shower. My friend likes it because the music is so loud that she can no longer hear me singing. So that's a win-win.
These videos are so much better than those on the "What's inside" channel. Yours are so meticulously disassembled, much much better filming, and more exiting to watch, instead of those brute force breaking stuff videos from the other channel.
"From chemistry course, of course we don't remember anything." So funny from a man who has so much curiosity and intelligence. Why don't they teach us in a way that is interesting? Why must school be so boring we only learn after we have walked out of the building?
Those aren't little batteries in a big battery. What you're looking at is the anode and cathode plates inside a lithium-ion battery. They are extremely dangerous to open... before being assembled the lithium on the anode plate will actually light on fire just by the moisture in your breath blowing on it. I work for the only manufacturer of 123A lithium batteries in the USA. If it says "Made in the USA", it was made in Columbus, GA, no matter what brand.
@@_ViPriN_ most of the smaller models would really benefit from like twice the battery size. That and really low power in the price category made me go for Xiaomi Mi speaker instead and I don't regret it.
The membranes with the jbl branding on both the ends are passive bass radiators. The passive radiator reacts to the vibrations of the air column (sound) created by the main speaker's driver. Now the material and size of the passive driver is set to resonate at the bass frequencies of the inside air column. So it vibrates at those frequencies and that vibration also disturbs the air column on the ouside twhich we hear as radiated bass.
@@ZAIDAAS99 the membranes are free to oscillate or move about a fixed point like a pendulum. A pendulum has a fixed time period (frequency). Now if you push the ball of the pendulum when the ball reaches you (at the same time period), the ball will go higher (the amplitude increases) but if you do the same but in a different time period it may not go that high or even reduce the amplitude ofnthe pendulum. The formula for the natural frequency of the jbl membrane is complicated and can't be discussed here but I guess you get the point.
i always thought the radiators on the side of jbl speakers could blow out but they can’t at all , i thought they were like subwoofers themselves that could blow if you played em too loud but damn they don’t
I have a JBL Charge that I use a lot and I love it! It's my go to Bluetooth speaker for watching videos or listening to music. I wondered how they packed so much great sound into something so small, now I know! Thanks a mill!!!
They move air without being a powered speaker. Essentially they're just frames with a cone & surround. They move when the powered speakers move. The air causes a push and pull force.
2:55 "its not dynamics at all!" sir, its a dynamic reflex device, a passive volumetric radiator... dynamic implies that something is ever moving or changing.
Bluetooth speakers with lights I recommend dindinmodern audio. And I've been using it for a year now and it still works great. The price is also very good.
Dont worry circuit blowing up or smoking is a mistake sometimes it happen to me yesterday but trying to power a cell phone by the battery connectors and it started to smoke because the power was either to powerful or the wires were touching together
