The electrical signal generated by the coil travels back along the speaker cable to the amplifier. Well-designed amplifiers have low output impedance so that this generated signal has minimal effect on the amplifier. Characteristically, solid state amplifiers have had much lower output impedances than tube amplifiers. So much so, that ...
An electrodynamic speaker driver, often called simply a speaker driver when the type is implicit, is an individual transducer that converts an electrical audio signal to sound waves. While the term is sometimes used interchangeably with the term speaker ( loudspeaker ), it is usually applied to specialized transducers which reproduce only a ...
The Air Motion Transformer ( AMT) is a type of electroacoustic transducer. Invented by Oskar Heil (1908–1994), it operates on a different transduction principle from other loudspeaker designs, such as moving coil, planar magnetic or electrostatically -driven loudspeakers, and should not be confused with planar or true ribbon loudspeakers.
The temperature was already above 80 degrees and rising. The work of maintaining the public water supply in a heat wave is crucial. But it needs to be done as safely as possible. That means ...
J.R. Reed’s three kids were scattered in different states across the country this week. They all had tickets to get home — on Delta.
When the decision to return to the office was made, shortly after Saxon’s arrival, Zoom employees wanted to know the “why,” he recalled. So the team told them. “We had a good, honest ...
Loudspeaker measurement. Loudspeaker measurement is the practice of determining the behaviour of loudspeakers by measuring various aspects of performance. This measurement is especially important because loudspeakers, being transducers, have a higher level of distortion than other audio system components used in playback or sound reinforcement.
The decision could strengthen the hand of businesses while reducing the sway of dozens of agencies, from the Environmental Protection Agency to the Food and Drug Administration and the National ...
