The picture above is of a LG TV Model Number 32LN5100. So how does this small speaker produce so much sound considered to be noise? I investigated and these are the results.
By the way this same TV costs 38,500 in the supermarkets like Tuskys and Nakumatt. Funny thing is that it only costs Ksh23000 at the LG authorized dealers like Al-Yassin in Nairobi’s Luthuli Avenue.
The first reason is that the TV itself has a powerful inbuilt Amplifier on its Main board. The Amplifier is small thanks to advances in the Microelectronics industry.
The second reason is the type of enclosure the speaker in enclosed in. This model of TV uses an enclosed type plastic enclosure. The enclosed type enclosure makes sure that the bass sound is much deeper. The speaker is tightly secured to this enclosure with adhesive and screws to get rid of unwanted enclosure vibrations that distort the good sound quality that the speaker produces.
The speaker itself is not magnetically shielded like the speakers used in CRT Televisions because of the magnetic effect speakers have on Cathode Ray Tubes. This means that the speaker is larger in size than it would have been with a magnetic shield.
There you have it that’s why those tiny speakers are loud, the secret lies in the powerful amplifier and the tightly sealed speaker cabinet.
