E11, a new start of FiiO's portable amp ( added some real photo ) - Page 8

If the stated 10 hours is really true, I can see it being a big deal breaker especially since this is targeted as a portable device.

 

I know the Arrow uses a 1200mAh battery.

 

 

Also, please give the mp3 player you're developing at least 16 GB of internal storage plus a microSD card slot. That way people don't have to bring around multiple microSD cards which they will probably lose.


The way Robert is able to make Arrow run for so long is because he implements an auto voltage/current limiting circuit that keep the opamp running on lower voltage and consume less current when extra output power is not needed. I would imagine putting such an extra circuit will only add complexity to the design as well as parts and manufacturing cost. If it runs on high current mode all the time, then Arrow will still have a short battery life. As James already pointed out, E11 is going to be cheaper than E7, so you can really pick one way or the other using a fixed voltage/current supply. Although a manual switch would probably be more feasible, sort of like those on 3MOVE / StepDance.

ClieOS, I never cease to be amazed at the depth of your knowledge for all things audio. wink_face.gif

Yeah, it is nice having someone here that knows what they are talking about.

Pardon me if I just missed this anywhere in the thread, but I certainly hope the DAP has the same height and width as the E11, if not the same chassis altogether. That way even if it's thicker it's still a match for stacking on each other.

Thanks for the kind words, mates. I doubt I know more about stuff than many around.

Anyway, a quick search over eBay reveal quite a few aftermarket BL-5B batteries that have much higher capacity (>1000mAh). I don't know how good are those rating or whether they will still fit the E11 battery compartment, but I think these are still worth a trial. AT the least, I think FiiO can test a few of them and see if they can be used or not. If yes, that will be great.

X2. Bigger battery better.

Don't be so modest. ;) You are like an encyclopedia of headphone audio knowledge. And you have the ability to convey complex concepts in easy to understand terms.

X3, even if the price needed to be increased slightly.

X2. I hate to make this into a CliOS appreciation thread, but your IEM mega comparo is brilliant.

 

Getting back the E11, approximately how long is it until it is released?

post #115 of 1326

March - it's been mentioned already.

post #116 of 1326

I usually work 10-12 hours days and am listening to music almost the entire time.  I'll be very unhappy if i cant get through an entire day, but not enough to sway me from not getting it.  :)

We will design a small switcher which can change the supply voltage , them it can make the playtime longer!

 

Also you can carry an extra battery and change the battery , so you get double playtime!
