OW Microspeaker: Simulation and Correlation with Measurements

Application ID: 78121

This model analyzes the electromagnetic, mechanical, and acoustical characteristics of the OWS-1943T-8CP (discontinued) speaker. Beside certain details, the geometry, material properties, and measurements are copyright by Ole Wolff.

Starting from the geometry of the speaker, an axisymmetric electromagnetic model is used to characterize the frequency-dependent response of the voice coil and electromagnetic circuit. This response is included in a 3D model where the vibroacoustic response of the speaker is analyzed and compared with measurements.

Ole Wolff is recognized worldwide for high-quality transducers, as well as unique design capabilities, which are supplied to a broad range of first-tier companies within the consumer electronics industry.

This model example illustrates applications of this type that would nominally be built using the following products:
