Advantages of Loudspeaker | disadvantages of Loudspeaker
This page covers advantages and disadvantages of Loudspeaker and its basics. It mentions benefits or advantages of Loudspeaker and drawbacks or disadvantages of Loudspeaker.
What is Loudspeaker?
Introduction:
The device which converts electrical signal input to physical vibrations in the form of sound
waves is known as loudspeaker. It is an electromechanical device which
is used in various applications right from hearing aids to air raid sirens.
Loudspeaker will produce more audible output compare to other identical speaker devices. The output depends on its construction and usage of applications.
There are two main types of speakers viz. wired one and wireless (bluetooth, wifi) based on its interface with transmission medium. Loudspeakers may be divided into two main groups viz. cone type and horn type.
Loudspeaker may also be categoried into diaphragm based and without it. Diaphragm based speakers include moving-iron, piezoelectric, magnetostatic, magnetostrictive, electrostatic, ribbon, bending, flat panel etc. The speakers without diaphragm include plasma arc, thermoacoustic and rotary woofers. There are speakers available based on digital technologies such as bluetooth, wifi etc.
Based on input form, speaker can either be analog speaker or digital speaker. Analog speaker amplifies analog EM waves to sound waves. Digital speaker first convert digital input to analog input and then generates sound waves.
The sound produced by louspeaker depends on two parameters viz. amplitude (i.e. loudness) and frequency. Loudspeakers are used in outdoor places to address larger audience during public meetings and presentations. Speakers are used in indoor places to addres few number of people.
Benefits or advantages of Loudspeaker
Following are the benefits or advantages of Loudspeaker:
➨They are available in different sizes based on installation
locations and applications.
➨They are very easy to separate out from main unit where microphone is also connected.
➨Loudspeakers are used to produce high amplitude sound waves to cover larger audience in vast region.
➨It is very easy to install, use and maintain without any training.
➨Wireless speakers are much more comfortable to install without any hassles of wiring.
Drawbacks or disadvantages of Loudspeaker
Following are the drawbacks or disadvantages of Loudspeaker:
➨They are bulky in size compare to normal indoor speakers.
➨They need large space.
➨They are prone to interference from nearby radio equipments or other radio microphones.
➨They consume large power due to its technical specifications.
➨Wireless speakers have range limitations.
➨They produce very large amplitude sound levels which are annoying for people in the closer vicinity.
Conclusion: There are different types of loudspeakers or speakers with each having their respective advantages and disadvantages. The above mentioned are generic advantages of loudspeaker or speaker and generic disadvantages of loudspeaker or speaker.
