Abstract
U ovom radu realiziran je sustav aktivnog dvostaznog zvučnika. Za konstrukciju zvučnika bilo je potrebno izraditi kutiju na niskotonski zvučnik i pomični sustav kutije visokotonskog zvučnika. Potrebne naponske razine dobivene su kupnjom gotovog ispravljača napona za najviši potrebni iznos, te uz korištenje linearnih regulatora napona dobivene su ostale potrebne razine. U sustavu skretnice signala implementirano je zbrajalo lijevog i desnog kanala ulaznog signala uz zaštitni pojasnopropusni filtar, regulator razine signala, niskopropusni filtar i visokopropusni filtar s atenuacijom razine visokotonskog signala, i sklop za generiranje diferencijalnog signala. Pločica sustava skretnice realizirana je metodom dead-bug. Za pojačalo korišten je gotov čip pojačala D klase na odgovarajućoj tiskanoj pločici za konfiguraciju s dva ulazna diferencijalna signala i izlaznom BTL aplikacijom. Na sustavu su napravljena osnovna elektronička i akustička mjerenja, kojima se poboljšala kvaliteta kompletnog sustava.
Abstract (english)
This graduation thesis is an implementation of an active two-way loudspeaker system. For the construction of the speaker, it was necessary to make a box for the subwoofer and a movable system for the tweeter box. The required voltage levels were obtained by purchasing a ready-made voltage rectifier for the highest required voltage, and with the use of linear voltage regulators, the other required levels were obtained. The signal crossover system is made with an adder of the left and right channels of the input signal with a protective bandpass filter, a signal level regulator, a low-pass filter and a high-pass filter with attenuation of the treble level, and a circuit for generating a differential signal. The circuit board for the crossover was implemented using the dead-bug method. For the amplifier, a ready-made D-class amplifier chip was used on a suitable configuration PCB with two input differential signals and an BTL output application. Basic electronic and acoustic measurements were made on the system, which improved the quality of the complete system.
