how if the amplifier not even connected to the speaker (load)?? are the energy use be significant??

Yup, I'm talking about transmition power. But for N8, it lack in trasmition power so the loudness also decrease.

So.. Paladin.. where do you bought your Nokia N8..??
wtb for my cousin !

of course its not connected to the speaker but it sent signals to your player. like your device, why your 3G mode will consume higher current than GSM mode.

Aspire is joking with you la, the 2nd batch dont have any news yet

so here another weird question... do u think loudness will affected by transmition power??? if u play with fm transmition before u will know i can make a tiny fm transmitter where only transmit within a feet radius but the audio signal within are still in max loudness... so if i place it within a feet to the radio it will still play as loud as it can but if i move a way the radio receive no signal at all... so from here u can see my actual fm signal are weak but the content (audio signal) are strong... so do u still think it have relation between this 2 factors??

Added on November 26, 2010, 10:43 ambro... that's bcoz it's a band different lah... highier freq band require highier power...
get back to the original question... the fm using same freq range and mostly normal fm transmition modulate 15Hz~15kHz signal so nothing much can be talk here as if the nokia fm transmitter sound low pitch compare with original sound it's understandable as highier pitch will need highier freq which will direct increase the power usage (same story here as the 3g band require highier power) but still what I dont understand is what the loudness have to do with extra power usage??

of course, signal make the transmission. if u need higher volume, you need to amplify it and transmit stronger signal. once u transmit stronger signal, it will drain your battery faster.

if u want a clear and good explanation, you better use a spectrum analyzer see the waveform and use oscilloscope to capture in details. simply use your fm modulator will get u the answer. im not good in explain. i only do testing. not manager..

too much info is unnecessary

ok... maybe 1 simple answer can get me out of the confusion...

HOW FM transmission control the loudness??

1. through amplitute?
2. through freq?
3. others?

not control the loudness but its about signal.
one more easy way to make u understand, you try use your fm modulator and n8 to compare. you will see fm modulator sound is louder compare to n8.
then you should know why both also using fm transmit but fm modulator is louder.

If you still want to know more about RF, then you should find expert in google. im not that level..

maybe i found the answer...

http://en.wikipedia.org/wiki/Dynamic_range_compression

good then...

Aigooo why all those technical jargon..The truth is our human ear veli the sentitit wan..You hear something not clear not loud, hissing..That mean it is bad liao..full stop..haha

found nothing about power usage saving regarding the soft loudness modulation....
so can I say another kiam siap ness on hw is the rootcause here....

Sound wave very subjective topic.

Its like BH-505 vs BH-503

I hear i said BH-505 not so good but for alot it sounds good enough.

Yeah humjan ear & tongue also diff wan..I said this restaurant good but another said yuckss..

Anyway, fromn what I can see, there are mixed supporter of FM transmitter here..1/2 said the FM transmitter is a god & the sound is the best & better than CD quality..For me my ear teling me it's a rubbish interm of SQ..except the convenient thing-lah..haha

How can FM transmitter win CD quality not even close.

Radio quality is acceptable not never the best.

Do post your photos here if u have lets share with the world
