From circuit the graph can see, sound gets stuck from sound or CD comes out to pass a little resistance to adjusted good volume to enter carry to put module, electronic scale down was passed after carry puts module to carry electricity of additional electricity is small enlarge implement. It is next result put, become sound wave to be passed finally. Friends may think, why sound does not pass enlarge directly, and should pass so much control?
It is carry puts module above all, want carry to put, because the voltage of the primitive news source of the input is too faint, it is millivolt is coming especially, so small frequency can't let driving result put identify and magnify effectively, produced such design hereby.

This is the commonnest thing in our life actually, when you hear sound, you should open CD opportunity above all, insert in next result put, box of that big iron, adjust volume, give voice with respect to the horn next. And box of that big iron, included volume adjustment, carry to put normally, electronic scale down, result puts these a few shares.
And traditional result is put won't include scale down implement part, scale down circuit includes sound box medium. And the optimal frequency that the advantage of scale down circuit matched a horn as far as possible namely answers limits, scale down implement compositive arrive result in putting, this also has the distinguishing feature that multimedia sound box just can have only. As a result of result put attribute the position that matchs one by one with loudhailer, signal is optimized in process of primitive before lean signal the more, the energy loss of its later period is smaller, the sound box scale down that compares a tradition in the utilization rate on energy changeover efficiency implement circuit efficiency wants tall, the waste of energy wants little.
Of this 3 Nuo dozen rub the key finds out comfortable scale down to nod namely, but the requirement that initial success improves acoustic quality! Now, attentive friend can ask, how does the function of scale down circuit come true, this piece of graph is the answer below:
Attenuation energy scale down implement tectonic, 3 Nuo N-35G is hit rub core skill
