Acoustic compressor driven by horn loudspeaker
Result description
The work is concerned with experimental study of a simple acoustic compressor driven by horn loudspeaker. Firstly, it is shown that geometry of resonator cavity together with complicated internal geometry of a horn driver can result in detuning of highermodes of the resonating acoustic system. Such a configuration enables excitation of high-amplitude shock-free standing waves. Secondly, the resonant system is supplemented with reed-type valve and a suction port in order to demonstrate possibility of simple acoustic compressor construction.
