Synopsis

Explore the core ideas behind how vibrating mechanical systems relate to electrical circuits. This practical text shows how an alternating-current receiver converts power to motion and sound, using clear diagrams and approachable math to connect theory with real devices.

Designed for students and practicing engineers, the book covers telephone receivers, oscillographs, and vibration galvanometers. It emphasizes hands-on methods, test procedures, and the way motional-impedance diagrams reveal an instrument’s behavior across frequencies.

• Foundational concepts linking mechanics and electromagnetism, with accessible explanations


• Techniques for measuring impedance, resonance, and key constants of receivers and vibrators


• Illustrative discussions of oscillographs, oscillographmeters, and related testing methods


• Appendices that gather further results and theoretical tools for advanced study

Ideal for readers of engineering history and practitioners seeking a solid, hands-on primer on electrical vibration instruments.

A propos du livre

Présentation de l'éditeur

The Bell telephone receiver is a marvelous instrument. It has undergone remarkably little change in structure since the first manufacturing model was produced by the inventor. It is reported that there were over 12,500,000 telephone receivers in public service at the end of 1920 in connection with the Bell system of the United States alone, or about one to every nine individuals in the then existing population. Nevertheless, there has been singularly little available information concerning the nature and properties of the telephone receiver as a machine. In order to understand quantitatively the delivery of speech by a receiver, its behavior as a machine must first be clearly understood. It is the object of this book to present, from an electrical engineering standpoint, the characteristics of telephone receivers (and of other vibrational instruments) as reciprocating electric motors, based on researches which have been carried on in the electrical engineering laboratories at the Massachusetts Institute of Technology and at Harvard University during the past fourteen years. The central idea in the preparation of the material for this book has been the wonderful and fascinating analogy between the laws of mechanics for a simple vibrational system, and the laws of electromagnetics for a simple alternating-current or oscillating-current system. An insight into one of these two systems provides a vision of the other. If electrical engineers received their fundamental training in the dynamics of mechanical vibrating systems, their conceptions of alternating-current circuits would doubtless be speedily grafted thereon. A ctually, they almost always receive their fundamental training on these matters in the study of the electromagnetics of alternatingcurrent circuits, so that their views of vibrating mechanical systems are most readily received through electric ana
