Abstract
The subject of the application is an acoustic amplifier according to the invention, comprising a platform and Helmholtz resonators, which is characterized in that at least four Helmholtz resonators (2, 3, 4, 5) are located under the platform (1). Each Helmholtz resonator (2, 3, 4, 5) has a resonance chamber volume, outlet neck length (6, 7, 8, 9) and bore cross-sectional area such that each constitutes a separate resonator amplifying the sound generated by one of the instrument's strings.
