<p>A vibratory compressor-actuator is disclosed for generating a high pressure acoustic waveform within a chamber (14) containing a working medium (15). The compressor-actuator comprises an actuator body (H1) solidly mounted to the chamber (14) with a vibrating armature (C2) spring-mounted within. The chamber (14) and actuator body (H1) are resiliently mounted so as to be vibratable. Owing to reaction forces, vibration of the armature (C2) causes vibration of the chamber (14) which generates an acoustic waveform in the medium (15). By matching the resonant frequency of the armature (C2) to the acoustic resonant frequency of the chamber (14) and driving the armature (C2) at that frequency, extremely high pressure within the chamber (14) may be obtained.</p> |
