Idejna zasnova in optimizacija kakovostnih zvočnikov za reprodukcijo glasbe

Meža, Matej (author), Lavrič, Henrik (mentor)

V diplomskem delu so predstavljeni zasnova, optimizacija in izdelava para zvočnikov, namenjenih reprodukciji glasbenih vsebin. Na podlagi začetne ideje in določenih izhodiščnih zahtev so bile izbrane ustrezne zvočniške enote. Podrobno je opisan postopek simulacije treh različnih iteracij, ki se med seboj razlikujejo po naboru karakteristik. Vsaka iteracija vključuje nizkofrekvenčno simulacijo, postavitev enot na sprednjo ploščo zvočnika ter simulacijo pripadajoče kretnice. Izvedena je bila tehnična in stroškovna primerjava vseh treh iteracij, na podlagi katere je sledila izdelava ohišja in montaža izbranih zvočniških enot. Po vtekanju nizkotonskih enot so bile opravljene meritve, katerih rezultati so služili za načrtovanje in izdelavo končne kretnice. Temu so sledile ponovne meritve in testiranje. Rezultati so potrdili izpolnitev vseh zastavljenih zahtev, z izjemo manjšega odstopanja frekvenčnega odziva na osi v območju med 100 Hz in 200 Hz. V zaključku so predstavljeni še končni stroškovni izračun ter pregled uporabljene programske opreme.

• Title: Conceptual design and optimization of high-quality speakers for music reproduction

Abstract

This thesis presents the design, optimization, and construction of a pair of loudspeakers intended for music playback. Based on the initial concept and defined design requirements, suitable speaker drivers were selected. The process of simulating three different design iterations is described in detail, with each iteration differing in a range of characteristics. Each iteration includes low-frequency simulation, driver placement on the speaker's front panel, and simulation of the corresponding crossover network. A technical and cost comparison of the three iterations was conducted, followed by the construction of the enclosure and installation of the selected drivers. After the proper break-in of the woofers, measurements were carried out, and the results were used to design and implement the final crossover network. Further measurements and system testing followed. The results confirmed that all design objectives were met, with the exception of a slight deviation in the on-axis frequency response in the 100 Hz to 200 Hz range. The thesis concludes with a final cost analysis of the build and a review of the software tools used.
