Purpose
A digital voice recorder is a multi-purpose device which can be used to record anything that releases sound waves. For example, a radio or even your own voice. The main purpose of a digital voice recorder is to allow you to record something and play it back another time. It also makes it possible to transfer the sound that you record onto your computer, rather than just listening to it out of the hand-held devices speakers.

Energy
A digital voice recorder uses 2 "AAA" batteries and transfers them into electrical energy. Once the energy is produced it moves tiny crystals around inside of the LCD Screen. Those crystals then become images on the screen and allow you to see the number of messages recorded, recording length, date, time, and the remaining battery power.

Controls
As seen on the device below a Digital Voice Recorder uses labeled buttons as its controls.
 * The Play/Enter Button allows you to play back and listen to each of your recordings.
 * The Record/Pause Button allows you to begin and stop each of your recordings, also to pause them while playing it back.
 * The Stop Button allows you to stop listening to recordings, and also to delete recordings.
 * The Fast-Forward and Rewind Buttons to the left and the right of the Stop Button allow you to skip forward in the next recording, or to go backwards into a previous recording.

Materials
For the usage of a digital voice recorder it is crucial to have an IC Chip. An IC Chip works as a storage device. It saves all of the recorded memory and organizes the multiple folders that you are able to set up. You also need batteries. 2 "AAA" batteries allow the recorder to power on and off, and complete each of its operations.

Science
A Digital Voice Recorder transfers batteries into electrical energy. This allows the LCD Screen to project images, also the device to complete all of its simple functions.

Design
A digital voice recorder is a very simple looking machine. It is small enough to fit in your pocket and has a large LCD Screen which covers about half of the device, the other half is home to the speakers. They are most commonly found in gray or black, but they are also available in a variety of colors.



Evolution
Over time the digital voice recorder has evolved from simple machines used for the same purpose, recording sound. In 1877 Thomas Edison invented the phonograph, which was a device invented to record speeches for business purposes. But, in the 1990's company's started using computer memory devices to make the machine more affordable and electronically up to date. The digital voice recorder takes the simple principal of a Flash Memory Drive and updates it using an IC (Integrated Circuit) Chip. IC Chips can also be found in cell phones, computers, and most, if not all modern electronic equipment. The high quality IC Chip allows the device to record over itself to reach its maximum storage space.
