Here is a diagram of an acoustic guitar. I built the guitar pictured in the diagram.
Below the diagram of an acoustic guitar you'll find explanations of the acoustic guitar's parts and their functions.
The guitar's parts labeled in red are must know and the parts named in black you should know.
Body: The body of an acoustic guitar is the large section of the guitar below the neck. The body amplifies the vibration of the strings when a note or chord is played. Different woods provide different tonal qualities to an acoustic guitar and affect the "voice" of the guitar. Plywood does not vibrate as freely as solid wood and makes the tone thinner sounding.
Bridge: The bridge attaches to the body and the strings get pinned into the bridge. The bridge is very important to the tone and plastic bridges are horrendous at transmitting sound. Once again the type of wood used here influences the voice of a guitar.
Bridge pins: Bridge pins are used to hold the strings in the acoustic guitar bridge.
Frets: The pitch of a note is created by the frequency of the strings vibration. When the string length is shortened by being pressed against a fret it vibrates faster and the pitch gets higher.
Headstock or Peg-head:
The part of the neck above the nut where the machine heads (tuners) are
attached. It usually has the guitar maker's logo.
Machine Heads or Tuners: Machine heads are sometimes called tuning knobs or tuning buttons. They tighten or loosen the strings. Cheap machine heads can be difficult to turn or loosen the string tension quickly, or worse yet, cause breaking of the strings because of sharp edges.
Neck: The neck is the long part of the guitar from the body up. The strings run along the neck.
Nut: The nut is the piece of material between the fretboard and the headstock which the strings rest upon.
Saddle: The saddle is the part that fits into the bridge which the strings cross. Cheap saddles may be plastic and do not transmit sound well. Replacing the saddle with a bone or tusqe saddle is the least expensive way to improve the sound of a guitar.
Soundboard: The soundboard, (also called a top), is the front of the body. This is where most of the guitar's tone is produced. A quality solid wood top is very important to the guitar's voice.
Sound hole: Contrary to popular belief the sound hole does not allow the sound to escape out of a guitar. It's size actually affects the balance of treble and bass tones.

Not all acoustic guitars are created equally. There are huge differences in prices and sound quality of acoustic guitars. Construction methods and the types of woods used affect the sound and playing ease.
