The essence of the voice of the essence of what can be the principle of the speaker

In the development of history, there have been many kinds of principle can change the speaker, so far still has a variety of energy conversion principle, although the most common to consumers is the loudspeakers in the high-end market, but often there are a lot of different energy transfer principle products, such as some attention to the audio industry or know the fancier moving iron type, electrostatic and so on. 

But for the audio system, the sound is actually the final speaker end, and the conversion compared to other do various front-end audio and digital signal, analog signal, the signal loss is the largest in the last step. Is the electronic signal through physical means to convert to sound, and as a speaker for long-term development, in history, there are a variety of different principles, but in fact, the core of these principles are relatively simple: the vibration of the film through the vibration of the sound. And just like before, in fact, the speaker itself is the entire audio system in the final sound performance accounted for the largest part of the. As the last step is the only one really can make people feel the sense of conversion, high efficiency and low loss requirements compared to before all the signal conversion requirements are high, and the electrical signal is directly converted into physical vibration and acoustic signal is not difficult, but for the user is also the most easy to find part of the problem.
