Abstract
An electric musical instrument includes a body having a front side and a rear side, a plurality of strings extending across at least a portion of the front side of the body, and at least one electric pickup to detect vibrations of the strings and generate a pickup signal. The instrument includes at least one speaker mounted at the rear side of the body, in which the speaker includes an acoustic driver and an acoustic deflector. The acoustic deflector is configured to receive acoustic energy propagating from the acoustic driver and deflect at least a portion of the acoustic energy. The instrument includes an amplifier to amplify the pickup signal to generate an amplified pickup signal, and drive the at least one speaker based on the amplified pickup signal.
