What is a loudspeaker and what is its purpose?
loudspeaker, also called speaker, in sound reproduction, device for converting electrical energy into acoustical signal energy that is radiated into a room or open air.
What is the difference between a speaker and a loudspeaker?
Senior Member. Loudspeaker is any device that magnifies sound so it can be heard (it can even refer to a megaphone, you know, that cone-shaped hand-held device people address crowds with). Speaker is usually what the sound actually comes out of (these are often covered with cloth-like or metal mesh).
What are the features of a loudspeaker?
Loudspeaker specifications have traditionally described the physical properties and characteristics of loudspeakers: frequency response, dimensions and volume of the cabinet, diameter of drivers, impedance, total harmonic distortion, sensitivity, etc.
What are the requirements of an ideal loudspeaker?
IDEAL LOUDSPEAKER
- would have an electroacoustic efficiency approaching 100 per cent.
- would have an acoustic output response that is independent of frequency over the entire audible range.
- would introduce neither harmonic nor intermodulation distortion into its output.
Can you use speakers as monitors?
You could use regular speakers as studio monitors but the sound will be biased. Studio monitors recreate the recorded sound as closely as they can, adding close to nothing to the original signal. You should not use regular speakers in your studio, but dedicated ones called studio monitors.
Why are loudspeakers used?
The purpose of a loudspeaker is to convert an electrical signal into sound waves providing the most faithful reproduction that is feasible for its design.
What happens when sound travels through air?
Sound is all about vibrations. The source of a sound vibrates, bumping into nearby air molecules which in turn bump into their neighbours, and so forth. This results in a wave of vibrations travelling through the air to the eardrum, which in turn also vibrates.
What is the most common type of loudspeaker?
By definition, a loudspeaker is an electroacoustic transducer that converts an electrical audio signal into a corresponding sound. The most common type of loudspeaker today is the dynamic speaker.
