Last week , weexplained the differencebetween $ 100 and $ 100,000 speakers . But in the name of clarity , we focused on traditional speaker system , around longer than Keith Richards . Here are the newer disturbed types .

OK , so the way verbaliser render audio is by moving air . In your standard setup , an alternate current run through a voice , turn it into an electromagnet that is attracted to and repulse from the lasting magnet in the driver , which moves the diaphragm ( the cone cell ) back and off . Air is run , phone is emitted .
But magnets are n’t the only way to generate speech sound , plainly . Here are a few other way talker can get aura a - shakin ’ :
Electrostatic Speakers
static speakersare probably the most well - known choice to traditional loudspeaker invention . In some fashion , they ’re a fate like your standard speaker system — a diaphragm moves back and off . What ’s different is the flesh of the pessary and how the system makes it move .
The stop is a thin film with electrically conductive material that ’s elongate out between two conductive plate called “ stators”—perforated steel sheets in Martin Logan ’s speakers — coat with an dielectric . Just as the articulation coil in a regular loudspeaker system is turned into an electromagnet by a stream , the contraceptive diaphragm and stator coil here are charge , creating an static playing field . As thecharge alternates between positive and negativethe diaphragm moves back and away , generating sound . The strong the charge , the more dynamically the diaphragm moves , and the louder the sound .
The claimed advantage of electrostatic speaker is that the entire diaphragm is force , not just the apex , like with a stock voice coil / cone setup , so not only do you get improved frequency ambit , you wo n’t get distorted shape from the diaphragm flexing . The flip side is that bass can be kinda weakly — though size serve — and high volumes can present some issues , given that the hard charges require for gamey volumes increases the chance for “ pyrotechnical electrical discharge ” ( in other words , electrical fire ) . Oh , and they’renot cheap . But theycan vocalize fairly good !

Plasma Speakers
Plasma speakersaren’tnew , but they are badass , and you canbuild your own . Or you know , just pay a lot of moneyto get some . The basic principle is , same as always , moving strain . Except , instead of attracter or an electrical field , a small-scale electric electric arc is wangle , create different pitches and book as the intensity is shifted . Maybenot the future , but lay the word “ plasma ” into any tech just makes it sound future - y.

Distributed Mode Loudspeaker
parcel out mood loudspeaker system technical school wasdeveloped by NXT . It ’s different from your stock diaphragm tech because traditional speaker diaphragms have to continue rigid . They vibrate but they do n’t bend , because that get aberration . Distributed - mode pessary are supposed to bend . Basically , bend waving are produced in the venire by electrical energy , and those vibration create sound .
One self-aggrandizing advantage of distributed mode loudspeakers is thatthey can be really thin . You do n’t need a big boxwood . In fact , NXT ’s big pitch is that almost anything can be a diaphragm — in 2002 , somebody really tried to market inflatable speakers free-base on NXT ’s technical school . But like other speaker unit option , it can have difficulty with bass . A bigger panel help oneself it out there , however . Warwick Audio ’s suspiciously tin foil - likenew flavourless , flexible loudspeaker technology actuallysounds interchangeable in rationale to NXT ’s DML — a thin membrane is unrestrained and vibrates in sentence to the electrical sign .

Planar Magnetic
Hey reckon , it ’s another technology using a thin membrane to move air!Planar magnetized speakersuse a slight film with a articulation curlicue printed on it ( think back to traditional Speaker ) . The roll is suspended between a pair of attracter . As the current alternates , the membrane moves and back off . As with most of these flimsy - stop setup , you postulate to go bountiful to get a better bass response , or just go with a disjoined woofer for low frequency . Oh , and they alsocost fate type O ’ dollars .
Carbon Nanotubes
Carbon nanotubes , the trendiest near - future material around , can of course be used tomake speakerstoo . Really slight ones . They really work out very differently , too . Nanotube speakers make use of thermoacoustics , just like thunder . The nanotube are work into a pic with electrodes attach at the end . An electrical stream is beam through the film , and as it changes , the air around the subway heats up or cools down in answer , expanding and sign respectively . pressing waves are created , and microphone boom , sound . The fidelity supposedly “ oppose that of conventional loudspeakers . ” The nanotubes themselves do n’t move at all , think of that technically , if the technology were harnessed , it could be used to make high - precision , first-rate - small - twisting speakers .
But here ’s a really smart as a whip estimate for next verbalizer that ’ll blow you aside : Make ’em cheesy without getting crappier . Now there ’s innovation !
