Active speakers are equipped with a special circuit inside the speaker. This group of circuits has the same power amplifier function as the power amplifier, which is the built-in amplifier amplifier. The active speaker can be better without any external power amplifier. The sound playback effect. Passive speakers are just the opposite of active speakers. There is no special amplifier inside the passive speakers.
What is a passive speaker? Passive speaker: There is no power amplifier circuit inside, and an external power amplifier is required to work. Passive Speakers are also known as Passive Speakers. Passive speakers are the household speakers that we usually use. The home theater speakers used in ordinary homes are basically passive speakers that require external amplifiers.
Passive speakers do not have an amplifier, but often have a crossover network and impedance compensation circuit. If you can configure the amplifier that is connected to the amplifier, the sound from the passive speaker is definitely better than the active speaker. You can also think of him as a "wooden box plus a horn". The benefit is that the sound will reach its optimum state without being disturbed.
How to connect a passive speaker to a computer? Because the sound card of a computer and a laptop does not have the function of a power amplifier, and the passive speaker itself does not have the function of power amplification, so if the passive speaker is directly connected through the socket of the sound card, the computer is only Can release the original analog signal, can not release the original sound quality effect.
How to make the passive speaker connected to the computer? In fact, it is very simple. If the friend wants to connect the passive speaker to the computer, it needs to be equipped with a dedicated power amplifier, connected to the computer and passive speaker through a dedicated power amplifier. Between, this is the computer case that we often see is a very large box.
Passive speakers and active speakers have their own advantages and disadvantages. Passive speakers have less built-in power amplifiers, so the sound of the playback is less affected by the circuit. The reproduced sound is better than the active speakers in sound quality. To be good, the disadvantage is of course that it is not directly used to listen to music. It needs to be connected to the power amplifier at any time. It is not easy to carry and is suitable for home use. The advantages and disadvantages of active speakers can be found here.
Through the introduction of the knowledge of active audio and passive speakers, I believe that friends should have a certain understanding of what is the passive speaker and passive speaker how to connect the computer and passive speaker power.
