Application of Matrix Analysis to Identification of Mechanical and Acoustical Parameters of Compression Drivers

Document Thumbnail

In previous work of the author special measurement methods were used to obtain the transfer matrices of compression drivers. This data was coupled with the results of the FEA simulations of horns. It made it possible to simulate the frequency amplitude and directivity responses of horn drivers without building actual physical horns. In this work, a different set of measurements is used to obtain the transfer matrix of a vibrating diaphragm. This approach results in a more detailed and flexible method to analyze and design compression drivers. Other parameters used in the identification process are the electrical parameters of the motor and the acoustical parameters of compression chamber and phasing plug. The method was used in design and optimization of the new JBL dual-diaphragm compression driver to be used in a new JBL line array system.
