Wireless Speakers

In today’s modern world wireless speakers are becoming ever so popular. There are two types of wireless speakers; infra red and radio frequency. Whenever purchasing wireless speakers make sure you test their range. As technology advances, wireless speakers are sure to replace traditional ones.

Speakers with Remote

Wireless speakers are like normal loudspeakers, but instead of using a cable to transmit the electronic signals carrying the sound information, the signals are transmitted by means of radio frequency (RF) waves. This is a great advancement in technology whereby the sound is transmitted from the system to the speaker through the air. In today’s modern world wireless speakers are becoming ever so popular.

Wire speakers cause a lot of entangled wires and are quite messy when setting up, especially when dealing with multiple speaker systems such as home theaters. You have to look for longer wires when you need to increase the distance between the speaker and the system.

They are available in most electronic shops in home theater systems, radios and CD players. This is because they are easy to assemble and can be set up almost anywhere. Wireless speakers can be easily set up outdoors in the garden. This is quite convenient, especially when having garden parties and ceremonies where people will not trip on any wires lying on the ground, having to keep looking out for them.

Most of these wireless speakers are weather proof therefore you can place them outdoors without much worry, but it is not advisable to leave them there for too long in case of heavy rain. Using wireless speakers also enables them to be placed on the other side of walls, whereas before you would have had to drill through the wall to enable the wire to go through. As long as you have them tuned properly towards the system, you will be able to receive good quality sound.

There are two types of wireless speakers; infra red and radio frequency. Infra red works with the same technology as a remote control where signals are sent to the speakers. The major disadvantage of infrared wireless speakers is that they usually require a direct sight with the system for them to produce clear sound. This means that any object that may be blocking their path can prevent them from being able to receive the sound.

Radio frequency is much better than infrared as its signal can pass through various objects including walls, but has the disadvantage of having static interfering with the quality of the sound.

For Radio frequency, wireless speakers consist of a main unit which consists of the loudspeaker and an RF receiver and a secondary unit which contains the transmitter of the RF signals. The transmitter is connected to the audio output of any audio devices like hi-fi equipment, TV’s etc. An RCA plug is normally used to achieve this. The receiver is positioned where the listener wants the sound to be, giving the listener the freedom to move the wireless speakers around without the need of using cables. The receiver unit normally contains an amplifier to amplify the audio signal to the loudspeaker and it needs to be powered by batteries or an electrical outlet.

The frequency range that is used by wireless speakers is normally the same range that is used by cordless telephones which is about 900 MHz. The signal can travel through walls and some manufacturers claims that the range in which the signal is transmitted can be up to 300 feet in radius. Most wireless speakers have a tuning knob to change the frequency that is transmitted by the transmitter to overcome possible interference with other wireless devices like cordless telephones or baby monitors.

Whenever purchasing wireless speakers make sure you test their range. This is to ensure that it’s suitable for your use. Some may have a very small range that cannot allow you to use them outdoors, therefore limiting your usage. Also test them with different surrounding materials and electronic devices, as this may also contribute to a reduction in sound quality apart from interfering with the range.

Wireless technology is improving as days go by, and new advances in radio transmission are being set up where better transmitters and receptors are being used to decrease the interference. Infrared systems have increased the number of transmitters to help reduce drop outs in sound. Sound quality is expected to get better soon, as the transmitters are being improved to be able to send quality signals. As technology advances, wireless speakers are sure to replace traditional ones.

Wireless speakers receive a lot of critique, because of RF interferences with other equipment like cordless telephones and of the poor sound quality some of the models delivers. Despite of the critique, wireless speakers are still very popular amongst consumers and the number of models available on the market is still growing.
