application of power amplifier is often confused
The speaker talked about efficiency and power amplifier output power matching problem, I once cite an example, a pair of speakers, 92dB as needed to kw (just can achieve beautiful sound, why? This relationship to the speaker and amplifier design orientation. First sound design makes a speaker why high efficiency but big eat Aaron. Modern loudspeaker, horn units are more than two decades, some even use only the combination of unit level admiral. Due to the use of units of numerous, partials design is more complex, each unit to indulge the working characteristic, efficiency and correction of the work unit, sound suppressor shao phase of capacitance, use, and the resistance and coil consumes power of many parts of the unit, although the sensitivity and the efficiency is very high, with little power can promote it, but in many unit work together, promote current, such as amplifier output current, light cause distortion, if forced the volume increased, and had no power itself when unloading protection design, will burn with the sound of the power amplifier, or units are burned.
Have a fever, think big misunderstanding of the amplifier must have good wattage, actually wattage size just one amplifier, the most important is the index of the electricity output at its feet of size is the key to flow. Have you noticed that a few kilograms on market of portable audio combination of travel by your power to also have hundreds of tile? Would you believe that only a few large battery power amplifier has the ability? As long as you think, hundreds of power of electric meal, you can cook at has several battery can try? These even manufacturers see also the Numbers, but some blushing head just to merchants hiss. Current, power amplifier must have strong power supplies, with powerful output level can do, when the current can cope with speakers, when many units to achieve beautiful sound effect, this is the flagship level or the modem top-grade amplifiers, only three hundreds of watts output, and the weight of the astonishing. Speakers and amplifier, the principle of cooperation is not only see the efficiency of the speakers, still need to see it on the current demands. Just to watch it with the efficiency and power amplifier, often made me said the example of error.
Talking about here, you might think, if I have a large wattage and current strong after class, can cooperate with the world any speakers, and??? You are wrong! A lot of people ever had tried some large current amplifier to push some efficient speakers, but rather than some fine effect and fine current wattage amplifier, why? This involves loudspeaker design problem of unit, especially those in the former design 7O speakers, and the horn of speakers. The general factory produces only a few of the amplifier to dozens of varieties of tile clay. When the speaker unit design efficiency and high sensitivity, the current needs only a few small, the amplifier can push to ring, but there are a lot of manufacturers still in producing such a loudspeaker JBL, KLipsh, Lowther Altec, q), etc. This kind of product, continuous-improving, some can not only, more efficient characteristics can be under a lot of power, but some products with low power amplifier can only beautiful sound, such as Lowther products, if you use some older power (such as more than 10 watts) completely lose its power that unique flavor and aesthetic Klipsh (from) speakers also engaged only suitable for some lower wattage and to promote sound beauty only beautiful sound power amplifier, if you use some strong currents and high wattage amplifier to push it is hard, only, croak completely lost its own timbre and temperament.
In addition to the above phenomenon, more interesting is that some of the low efficiency of the speakers, with some fine power amplifier to push it, also push, which paved and how explanation? In addition, some people use a 100 to push the machine part it to dozens of water and power amplifier, connect lose, this is why? In addition, a few of bravery, sounds, its force than some dozens of water of stone machine, nor how much difference in where? Why a dozens of the speakers will burn unit power amplifier and a hundred tile with volume and does not burn unit? I believe, it was perplexed. Fever
