Abstract

U ovom radu proučavat ćemo princip rada električne gitare. Promotrit ćemo samu konstrukciju i građu gitare te opisati kako svaki dio utječe na zvuk koji nastaje u konačnici. Proučit ćemo titranje žice i stojne valove koji su nastali trzanjem žice. Potom promatramo u kojem su odnosu titranje žice i pickup zavojnica električne gitare. Usporedit ćemo spektre i zvučne valove nastale trzanjem žica akustične gitare i električne gitare. Također ćemo uspoređivati zvučne valove kada gitaru direktno spojimo u osciloskop i kada koristimo distorziju na pojačalu. Opisat ćemo rad pojačala i zvučnika, te utjecaj ton blende i trzalice na zvuk.

Abstract (english)

In this paper, we will study the principle of operation of the electric guitar. We will look at the structure of the guitar and describe how each part affects the resulting sound. The most important elements for us are the vibration of the string and resulting standing waves.. We will observe the relationship between the vibration of the string and the pickup magnet of the electric guitar. The emphasis will be on comparing the spectra and the sound wave created by plucking the strings of an acoustic guitar and an electric guitar. Comparison between the sound waves when we connect the guitar directly to the oscilloscope and when we use distortion on the amplifier will also be made. We will describe the operation of amplifiers and speakers, and how the tone knob and the guitar pick affect the sound.
