Q: Were loudspeakers invented during the development of telephone systems in the late 1800s? ¶
A: Yes, and but electronic amplification by vacuum tube beginning around 1912 made loudspeakers truly practical.
Q: Is a loudspeaker radiating into an infinitely large space and mounted on an infinite baffle? ¶
Q: Are loudspeakers the oldest form of loudspeaker system? ¶
Q: Are loudspeakers separated by a quarter wavelength or less? ¶
A: Yes, low frequencies are affected the most.
Q: Is a loudspeaker known as an active loudspeaker? ¶
Q: Is a loudspeaker transparent? ¶
A: Yes, and stretchable and flexible.
Q: Are loudspeakers said to be "out of phase" or more properly "out of polarity"? ¶
A: Yes, Given identical signals, motion in one cone is in the opposite direction of the other.
Q: Are loudspeakers perceived? ¶
Q: Are loudspeakers large by nature? ¶
A: Yes, and the bass rolls off at a frequency corresponding to a quarter wavelength of the narrowest panel dimension.
Q: Were loudspeakers manufactured by Danish engineer Peter L? ¶
A: Yes, Jensen and Edwin Pridham in 1915, in Napa, California.
Q: Was a loudspeaker invented by Oliver Lodge in 1898? ¶
Q: Are loudspeakers often very fragile—some can be torn by a strong gust of air? ¶
Q: Is a loudspeaker driven by modulated electric current that pass through a "speaker coil" which then magnetizes the coil? ¶
A: Yes, and creating a magnetic field.
Q: Are loudspeakers found in devices such as radios, televisions, portable audio players, computers, and electronic musical instruments? ¶
A: Yes, Larger loudspeaker systems are used for music, sound reinforcement in theatres and concerts, and in public address systems.
Q: Is a loudspeaker subjected to rough handling? ¶
Q: Are loudspeakers inefficient transducers? ¶
A: Yes, only about 1% of the electrical energy sent by an amplifier to a typical home loudspeaker is converted to acoustic energy.
Q: Was a loudspeaker connected to? ¶
