Current, first sound box of countrywide that 3 Nuo hold rub machine contest is in of like a raging fire in undertaking becoming. Among them, more ace thering is no lack of is participated in. Compare with them, small make up this to start work ability, but was differred old far. But, doing a miscellaneous work still is possible. So, we will be done to yuan of parts of an apparatus of sound box interior in succession a few explain smally. Today, we first from result unlock only then!

The AV result that day dragon rolls out is put

Result put, its real formal name should be power amplifier, english name: PowerAmplifier. The electricity that it uses dynatron controls function or the voltage of field effect canal controls action to be the power changeover of power source the electric current that changes according to input signal. Because, sound is the wave of different amplitude and different frequency, communicate signal electric current namely. And the β that the collector electric current of dynatron is base electric current forever times (the communication enlarge that β is dynatron is diploid) . Apply this, be like base of infuse of will small signal, criterion the β that the electric current that collector has shed can be equal to base electric current times. Next, use this signal again lie between straight capacitance segregation to come out, got electricity (or voltage) it is former β the big signal of times, this phenomenon makes the enlarge action of dynatron. Through constant electric current and voltage enlarge, finished power enlarge.

And fall as a result of a lot of circumstances, the rated output power of lead plane is insufficient the task that drives whole sound system. At this moment, be about to be mixed in lead plane broadcast outfit power amplifier is added to complement between equipment requires power separation, and power amplifier rose in whole sound system " organization, harmonious " hub action, going up somehow dictate is worn whole system whether offer good acoustic quality output.

Note: Usually, we put result discharge way in the sound box of casing interior to call multimedia sound box. In the meantime, also can call active sound box.

Press result the electric way that the result in putting puts a valve is different, can divide for armour kind result put (weigh A again kind) , second kind result put (weigh B again kind) , Jia Yi kind result put (weigh AB again kind) with man kind result put (weigh D again kind) .

Armour kind result putting is to point to the whole cycle in signal inside (of sine wave losing two half weeks) , any power output component of amplifier won't appear electric current ends (stop to output namely) a kind of amplifier. Armour kind the meeting when amplifier works produces high fever, efficiency is very low, but inherent virtue is nonexistent hand in more lack fidelity. Chanduan amplifier is armour kind working way, push-pull amplifier can be armour kind, also can be second kind or Jia Yi kind.
