Abstract

Razvoj zvučnika počeo je davnih 1860-ih godina, te do danas konstantno napreduje. Pojavljuju se novi materijali (karbonske membrane, neodimijski magneti), tehnologije izrade (aluminijske košare i promjene u dizajnu) koji uvelike pridonose kvaliteti reprodukcije, ali bez paralelnog razvoja zvučničkih kutija bi taj razvoj bio znatno usporen i ne bi lučio tako dobre rezultate. Zvučničke kutije (pasivne ili aktivne) predstavljaju ključni dio zvučnog sustava. Zvuk u akustički lošoj prostoriji zvuči loše neovisno o zvučnom sustavu, ali zvuči loše samo u toj prostoriji dok zvuk koji izlazi iz loše konstruirane zvučničke jedinice zvuči loše gdje god se nalazili. Postoji nekoliko osnovnih tipova zvučničkih kutija, različitih po kompleksnosti, kvaliteti i utjecaju na signal, ali sve one moraju zadovoljavati neke osnovne parametre uvjetovane zvučničkom jedinicom koja se ugrađuje Thielle-Smallovi parametri koji ocjenjivanjuju zvučničke jedinice preko nekoliko desetaka parametara nam pomažu prilikom odabira tipa zvučničke kutije i njezinog dizajna.

Abstract (english)

Development of speakers has started in the late 1860s and has continued till today. There have been new material advancements (carbon membranes, and neodymium magnets), technologies of production (aluminum baskets and changes in design) which have influenced quality of reproduction, but that advancement would be much slower without parallel development of speaker enclosures and wouldn't yield such great results. Speaker enclosures (passive or active) are key component of every speaker system. Sound in acoustically untreated room sounds bad regardless of the system, but it sounds bad only in that room whilst sound from bad enclosure sounds bad wherever we are. There are few basic types of speaker enclosures, different by complexity, quality and influence on signal, but all of them have to comply to basic parameters set by the speaker unit which is being embedded into it. Thielle-Small parameters which grade speaker units over couple dozen parameter help us in choosing the right type of enclosure and it's design.
