Abstract

Przedmiotem zgłoszenia jest wzmacniacz akustyczny według wynalazku, zawierający podest oraz rezonatory Helmholtza, który charakteryzuje się tym, że pod podestem (1) znajdują się co najmniej cztery rezonatory Helmholtza (2, 3, 4, 5). Każdy rezonator Helmholtza (2, 3, 4, 5) ma taką objętość komory rezonansowej, długość szyjki wylotowej (6, 7, 8, 9) oraz pole przekroju otworu, by każdy stanowił oddzielny rezonator wzmacniający dźwięk generowany przez jedną ze strun instrumentu.The subject of the application is an acoustic amplifier according to the invention, containing a platform and Helmholtz resonators, which is characterized by the fact that under the platform (1) there are at least four Helmholtz resonators (2, 3, 4, 5). Each Helmholtz resonator (2, 3, 4, 5) has such a volume of the resonance chamber, the length of the outlet neck (6, 7, 8, 9) and the cross-sectional area of the hole that each constitutes a separate resonator amplifying the sound generated by one of the strings of the instrument.
