Abstract

The system has a housing (10) has a resonance chamber (18) separated from the residual housing area by a tubular acoustic neck (19). The housing has two sections, connected esp. by ultrasonic welding or heated tool welding. Acoustic neck and/or resonance chamber are defined by peripheral surfaces of first and second sections. Both sections have similar surfaces, which define the resonance chamber. There are passages between acoustic neck and resonance chamber, or acoustic neck and housing volume.
