Experimental investigation of structural vibrations inside a balanced armature receiver

Research output: Contribution to conferencePaperResearchpeer-review


We will present experimental characterization of receiver vibrations, based on bidirectional exterior and interior laser vibrometer measurements. The receiver is placed in mechanically well-defined boundary conditions, and measurement points are precisely focused on the external surface of the receiver housing, as well as internally on the moving armature tip and sound producing diaphragm. The results are validated against fitted and simplified mechanical lumped element models. We discuss how well these different lumped element models can predict the external and internal receiver vibrations, and outline which modifications are useful to accurately capture the physical behavior of the devices.
