Thanks also to my loving parents, who have always been there for me. The Early Years of the Acoustic Phonograph Its developmental origins and fall from favor 1877-1929 "Mary had a little lamb, its fleece was white as snov^. And everywhere that Mary went, the lamb was sure to go." With the recitation of a child's nursery rhyme, thirty-year- old Thomas Alva Edison ushered in a bright new age--the age of recorded sound. Edison's successful reproduction and recording of the human voice was the end result of countless hours of work on his part and represented the culmination of mankind's attempts, over thousands of years, to capture and reproduce the sounds and rhythms of his own vocal utterances as well as those of his environment. Although the industry that Edison spawned continues to this day, the phonograph is much changed, and little resembles the simple acoustical marvel that Edison created.

  • The Lab Notebook
    Thomas Edison National Historical Park National Park Service U.S. Department of the Interior The Lab Notebook Upcoming Exhibits Will Focus on the Origins of Recorded Sound A new exhibit is coming soon to Building 5 that highlights the work of Thomas Edison’s predecessors in the effort to record sound. The exhibit, accompanied by a detailed web presentation, will explore the work of two French scientists who were pioneers in the field of acoustics. In 1857 Edouard-Léon Scott de Martinville invented what he called the phonautograph, a device that traced an image of speech on a glass coated with lampblack, producing a phonautogram. He later changed the recording apparatus to a rotating cylinder and joined with instrument makers to com- mercialize the device. A second Frenchman, Charles Cros, drew inspiration from the telephone and its pair of diaphragms—one that received the speaker’s voice and the second that reconstituted it for the listener. Cros suggested a means of driving a second diaphragm from the tracings of a phonauto- gram, thereby reproducing previously-recorded sound waves. In other words, he conceived of playing back recorded sound. His device was called a paléophone, although he never built one. Despite that, today the French celebrate Cros as the inventor of sound reproduction. Three replicas that will be on display. From left: Scott’s phonautograph, an Edison disc phonograph, and Edison’s 1877 phonograph.

  • ACP+: DIY Preamp and Headphone Amplifier Project
    ACP+: DIY Preamp and Headphone Amplifier Project At the first Burning Amp Festival in 2007, a young attendee, Nelson Brock and his parents Dana and Liz, displayed a nice pair of loudspeakers using the Pioneer Bofu full range drivers in Voigt enclosures. They were so well received that subsequently the Brock family hosted a DIY audio event called “Speaker Camp”, where a group of enthusiasts showed up on a weekend day and assembled a bunch of them to take home. The success of this inspired the later effort called “Amp Camp”, and I had the opportunity to design the amplifier, referred to as the Amp Camp Amp (ACA), a small single-ended Class A amplifier powered by a desktop switching supply and delivering about 5 watts. This effort was also a success, and years later the ACA kit is still popular at the diyAudio website and has also enjoyed a small upgrade in power and performance. So here we are in 2019, and the people organizing the Burning Amp Festival had the idea of joining an “audio camp” type of event to BAF, and asked me to design a preamp that would also serve to drive headphones. The result is this circuit: The gain stage for each channel resembles a miniature version of the First Watt J2 amplifier, with an input circuit using a differential pair of P channel Jfets Q1 and Q2 biased by a constant current source Jfet Q3, and driving a Common Source Mosfet Q6 which in turn is biased by Mu-Follower Q5. Q5 is controlled by opto-isolator Q4, which sets a DC voltage based on the sum of the currents through Q5 and Q6, keeping that sum constant.
