Abstract

Wzmacniacz akustyczny, zawierający podest oraz rezonatory Helmholtza, 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. Ponadto, przez każdą z komór rezonatorów Helmholtza (2, 3, 4, 5) przechodzi ruchomy pionowy drąg (12).The acoustic amplifier, containing a platform and Helmholtz resonators, 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. Moreover, a movable vertical rod (12) passes through each of the Helmholtz resonator chambers (2, 3, 4, 5).
