Portable Sound and Video products are those that you can easily carry with you while you're on the go. Some examples include cell phones, portable computers, camcorders, DVD players and game consoles. There are many different kinds of these products available. For instance, there are walkie-talkies, earbuds, microphones and GPS/RFID tags to name a few. A few of them are built into cell phones while others can be attached to your computer with the help of a USB cable.The audio equipment used in these devices can be classified according to the component they use for. Stereo microphones are common as they reproduce sound very accurately and efficiently. Mono microphones are popular as they are cheap and easy to use. In addition to stereo microphones, there are two other types of microphones available - microphones that produce sound through more than one driver, called multiple driver microphones that are used for input and output purposes, i.e. they're used to send sound from audio sources to an audio device like speakers.One example of a digital audio recorder is the Bluetooth enabled cell phone. This small recording device has a microphone that can be used to capture sound and transmit it to a computer or other device for storage and playback. Some examples of Bluetooth enabled devices include walkie-talkies, portable tape recorders and laptop computers.Digital audio recorders can also be classified according to the source of the sound they capture. One example of this is the microphone known as an open box microphone. These microphones are mostly used by amateurs for home recordings. The microphone uses low power to capture audio and converts the signal into digital data that can then be stored or transmitted over a network such as the Internet.Next up are speaker systems. There are many varieties. Some are set up for listening to music while others are used to play audio while driving. Speakers that allow the user to plug in speakers and headphones are known as set up speakers. These may also include auxiliary input devices such as line out adapter and speaker adaptors.The next type is the video product. A video product typically produces video content such as stills or movies. A portable DVD player with built-in digital video recorder or DVR is one example of a video product. Other products such as digital cameras or camcorders may also capture video. The captured video is then displayed on a TV or computer monitor.Another type of product is the audio product. Audio products can either be used in conjunction with video or they can act as an independent unit. Some examples of audio products include mp3 players and personal digital audio workstations ( PDAs). Some audio products also include inputs for microphones and speakers. In the case of the PDA, some of the software programs can capture audio input and output into digital data that can then be sent to a computer.Other types of portable sound & video products include printers, projectors, televisions, DVD players and radios. Each of these products has their own unique features. Depending upon what the application is intended for, the different types of product may differ. As technology advances, new types of portable sound & video products are developed. Manufacturers are always looking for new ways to expand their product lines.One type of portable unit that has become popular is the hand held portable TV.

HDTV's offer twice the resolution of regular television sets and are now available in home formats as well as for use in the car. High definition technology offers a clearer picture than previous televisions and video games. Some companies are even using high definition cameras to create motion graphics for their products. The availability of HDTV programming and high quality audio products have made it possible for virtually anyone to enjoy high definition TV.It is important to understand the difference between portable and fixed products. Portable devices are lighter and more collapsible, and therefore take up less space in the vehicle. Fixed products cannot be transported from vehicle to vehicle. Fixed units also generally come with a limited warranty and usually need to be returned to the retailer if they are not satisfied.
