EnKlein Technology and Innovation

20th Century and the Rise of Amplified Sound

Historically, mechanical amplification's first use was the Edison phonograph in 1857-1877. Siemens, in 1877, was awarded the first loudspeaker patent; an argument for the telephone predating this is viable.  

The first public use of electrified loudspeakers was in 1912 at a Chicago water carnival, courtesy of the vacuum tube.   The Magnavox was born.  

In 1915, Bell Labs employees Harold Arnold & E.C. Wente were developing an amplified phonograph system with the following requirements:

  • Tube amplification.
  • Balanced armature speaker and driver
  • Microphone to match the first two requirements.

This Bell Labs creation fueled the flame for amplified sound and music, including tube amplifiers, preamplifiers, realistic-sounding speakers, and the condenser microphone.  

By the 1920s, the world was smitten with amplified sound and music. The global demand for amplification was enormous, spurring innovation with radio, public address, dance halls, and theaters. The quest for high fidelity was born. Scientists, engineers, and entrepreneurs around the globe leaped at the opportunity this emerging market created.

 With this public want, comes more technical issues, including viable transatlantic telephone lines. This is where amplified sound transmission science over cables started in earnest.

It is an easily demonstratable fact the distance between the sound source and speaker placement can result in distortion. 

Oliver Heaviside's mathematical work with Maxwell's equations proved this phenomenon mathematically and created the science of sound transmission. This paved the way for practical applications, creating viable long-distance speech over metal cables. However, analog transmission suffered from harmonic detail loss. As a result, even close family members had to identify themselves at the beginning of a conversation, creating telephone etiquette rules still used in the 21st century.

Telephony bandwidth, 300 – 3,300 Hz, is not conducive to music transport; However, Heaviside's work provides critical scientific insight into solutions for accurately transporting music over wires.

Problem Statement

Modern audio sources face a common challenge: delivering music to the listener in its purest form. The transmission lines, also known as cables or conductors, have limitations that can be easily described. For instance, copper conductors have a slower velocity than silver, and the diameter and surface area of the conductor can limit current. However, this only describes the capability of the bare wire. The dielectric, shielding, and bundling can negatively affect the music as readily as the noisy 21st-century environment. 

The question is:

How can we utilize the conductor to its fullest potential?  

The solution is discovered by examining behaviors and tendencies at the highest frequency down to the electron level as individual points and groups.

Ensure the electron flow pathway is free from coupling effects, velocity changes, “Speed Bumps” from material imperfections, and frequency-based impediments created by joins and dissimilar metals. 

Differentiating between free random electrons and "herding" anomalies along the signal path assists in detailing remedies based on material science and electromagnetic fields. 

This is where EnKlein excels in the industry. Our founder holds over 30 patents in transmission science, AI, and signal analytics, covering frequencies from human hearing to beyond visible light spectrum for commercial and government systems. 

EnKlein technology optimizes performance for each specific cabling task (AC/DC Power, analog or digital signal transport, and reference point grounding), providing the listener with a thoroughly immersive experience.
