Wireless Speaker System – Details

Consumer electronics especially in the music realm has come a long way. Only 25 years ago, music was store in vinyl 12 inch records which although had relatively good sound, were subject to rpid wear and tear caused by scratching. Then we the consumer electronics giant Phillips with some help from Sony invented the compact disc. The compact disc or CD took the world by storm with its studio-style digital sound quality and durability. The CD was also smaller than the vinyl and therefore easy to store and transport. In the same manner that music storage evolved and developed, so did the musical players. To play the CD the industry came up with CD players and Discman’s which were the CD Player equivalent of the Sony Walkman. This meant that people could actually carry CD-quality music with them wherever they went and this was a great advantage especially to people who were given to the outdoors. As music moved outdoors, so did the speakers. More consumer electronics manufacturers jumped into the idea of producing speakers that could be used outdoors.
Speaking of speakers being outdoors, electronic manufactures realized that more and more people need to listen and enjoy their music outdoors, hence wireless outdoor speakers. Wireless speakers can also be used indoors and have become popular due to their convenience. Wireless speakers work on the same premise as a radio. The tuner, player or music receiver plays the music and a device inside the player converts the music signals into analog signals. Then a decoder inbuilt into the speaker converts the signal back into digital and into sound. This is done instantaneously to where the listener does not notice the conversion.
Wireless speakers as we mentioned have gained their popularity from the fact they are very convenience. Coming in smaller size than conventional speakers, wireless speakers can be placed inconspicuously under the couch and other places where they are not so obvious and where their appearance does not influence the interior decor of a room. This results to less clatter. They can also be positioned strategically where the sound will be best. Because of their smaller size wireless speakers can also be easily transported.
While they do have obvious advantages, wireless speakers are not without critics. One of them is that although they are referred to as wireless, they do indeed have a connecting cable running from the speakers themselves and into the electrical outlet. This is because they need power. IPod wireless outdoor speakers use batteries and can be a cure for this although the music will last as long as there are batteries (if you are outdoors)
Wireless speakers also work the same way a radio works; by receiving signals from a sending device. While this is common technology, it is not perfect because it is subject to interference. If there are other wireless devices in close proximity with the wireless speakers then this can ultimately affect the quality of the sound.

Wireless Speaker System – How It Works
Author: Theodore Cartman
More and more music lovers are transitioning from the regular conventional speakers to wireless speakers. Regular speakers are still popular and there are people who invested a lot of money in conventional speaker boxes and these are still as great as ever But those in tune with music have began to see a limitation with regular speakers. One of them is the unsightly wires that run from the music receiver or tuner to the speakers. If you have a lot of speakers then the wires can form a tangled mess behind the unit and when it comes time to untangle them the whole exercise can become a major headache. Then there is the risk of someone tripping on the wires and hurting themselves not to mention that if there are little children within the vicinity of the wires they can pull them out and interfere with the sound. In some cases, these cables have started fires in houses and apartments. Thus the strong case to transition to wireless speakers.
Wireless speakers are just normal speakers in appearance but rather than use a transmitter cable from the tuner to the speakers, they rely on radio frequency waves in much the same way a radio or a cell phone works. It is not uncommon to see the speakers, the tuner and a third device whose sole purpose is to transmit the signal. This device, called the transmitter, is connected to the tuner via a cable. An amplifier is also used and this is to magnify the signal and boost its quality. The signal transmitter also has a cable running from it to the electrical outlet on the wall. The frequency range for wireless speakers is the same as that of wireless or cordless phones, about 900MHz. The sound can even travel through walls for a distance of up to 300 feet.
One advantage with wireless speakers is that the sound can actually be transmitted through walls. This means that the speakers need not be in the same room as the tuner. For some, this is especially workable in the event that they want speakers in the bathroom or kitchen or even outdoors. Wireless speakers are also ideal in an zone that has small children or animals in that they can be placed out of range where they cannot access them or interfere with the sound.
Wireless speakers are definitely going to be the way people listen to music in the future even though conventional speakers with their wires are still in use in a lot of homes. One downside of wireless speakers is that they are limited in the distance where the frequency signal can reach. Wired speakers can function regardless of their distance from the tuner as long as the cable can reach them. Also, wireless speakers are subject to sound distortion because the signal is transmitted in the air much in the same way that a radio transmits. This means that if there are other wireless devices within the same vicinity the sound quality may suffer.
