The Diaphragm is the thin larger diameter piece which is used to listen to high frequency sounds such as crackles or wheezing in the lungs.
The Bell is the smaller diameter piece that usually has a bowl shape. The bell is used to listen to low frequency sounds such as turbulent blood flood which could indicate bruits or blood swirling through blood vessels which are partially occluded due to plaque build up.

Who made the first stethoscope and when Was it at all similar to the type of stethoscope we see today?
The origins of the stethoscope date back to 1816 in France. French doctor Rene Laennic invented the first device for listening to a subject's chest. His first stethoscope was little more than a tube created out of rolled paper. The first stethoscope was made by Rene’ Laennec in 1816. It was different to todays models as it was monoaural or one earpiece. His discover was actually made of stacked paper rolled into a cylinder shape, but he soon began to manufacture them made from wood. Binaural stethoscopes first appeared in the 1850's or 1860's and eventually developed into what we see today.
What are major parts or components of a stethoscope?
The parts of a stethoscope(distal to proximal) are:1. Chest piece2. Tubing3. Ear tubes(binaural)4. Ear pieces5. (The most important part)1. Chest piece:Is applied to the chest. It consists of a diaphragm(for high pitched sounds) and a bell(for low pitched sounds) OR a just a diaphragm. The diaphragm is flat, about 5 cm(2 inches) in diameter. The other side has a bell, which is conical in shape, about 2.5cm(1 inch) in diameter. [can be compared to a microphone which receives sounds!!]2. Tubing:Is usually made of PVC, is about 45cm long and splits to attach to the two ear-tubes.3. Ear tubes:Two in number, usually made of steel, conduct and amplify the sounds transmitted by the tubing. sometimes has a spring in between to maintain shape and fit snugly over the ears.4. Ear pieces:Two in number, each attached to the ear tube on either side. Fits snugly in the ear. Can be hard or soft type.(These must face forwards and medially - the direction of the external ear canal)5. The Most Important Part! :You might be wondering what else is left in the stethoscope, that too MOST IMPORTANT???It's the part between the ears!!!!Yes, the brain of the examiner. Without it having proper knowledge, a keen sense of observation, and the ability to deduce, it's impossible to assess what's happening beyond the chest-piece!!

What is the history of the Stethoscope?
For decades, physicians relied almost solely on the stethoscopeFrom the time it was invented in 1816 until early this century, the stethoscope was the most reliable and informative tool available for diagnosing cardiovascular disease. Although other, more sophisticated diagnostic methods have come into use since then, the stethoscope has never been discarded."At the turn of the century...diagnosis relied on taking a history and examining the heart with a stethoscope, and treatment consisted mainly of rest and a few standard oral medications." said W. Bruce Fye, a University of Wisconsin cardiologist and historian.The stethoscope battles embarrassmentSince the time of Hippocrates, physicians listened directly to patients' chests as they tried to assess cardiac health. The inventor of the stethoscope, Rene Theophile-Hyacinthe Laennec, relied on this method, too.One day, when he needed to examine an obese young woman, Laennec hesitated to put his head to her chest. Remembering that you can hear a pin scraping one end of a plank by putting your ear to the other end, he came up with the idea for a stethoscope prototype. He rolled a stack of paper into a cylinder, pressed one end to the patient's chest, and held his ear to the other end."I was surprised and pleased to hear the beating of the heart much more clearly than if I had applied my ear directly to the chest," Laennec said in 1816.Laennec's first manufactured stethoscope was a simple wooden tube. A succession of different designs followed his, including, eventually, a "binaural" type with two ear pieces. In 1850, George Camman substituted rubber for stiffer materials and made a more comfortable model-the forerunner of today's stethoscopes.

How can I listen to my heartbeat without using a stethoscope or any type of microphone?
If you literally mean can you listen to your own heartbeat then maybe not. But, if you mean can a person's heartbeat be heard without an instrument, then the answer is yes. In the early days doctors rested their ear against the patient's chest to hear the heartbeat. A doctor in those puritanical times, realizing ladies did not like him to press his ear to their bosoms, rolled up a tube of paper, pressed it to their bosom and put his ear to the other end. This was the origin of the stethoscope.
