Sound From Substance; Acoustic Design Reconsidered, by R.J. Wakeman
This new work covers diaphragm design (including the various materials from which they were/are manufactured), sound box/reproducer design, horn design, and even diaphragm-only machines such as the Lumiere and Pathé Actuelle. Even the Stroh violin and various radio drivers and radio speakers are included. Finally, this article includes the original illustrated 1914 Victor instructions on:
Repairing The Victor Exhibition Sound Box
No matter how long or how seriously you've been studying the design of antique phonographs, you'll learn something from this landmark work. Once again, we thank Mr. Wakeman for his exhaustive research and for allowing the APS to freely share it online.
