A type of instrument used in the 1900s to measure very low currents by sending beams of light to the mirror and reflecting this back onto a wall using the mirror as an amplifier. Small currents in V/A can display a displacement of a few inches on the wall. This instrument has to be balanced, hence the air bubble level and adjustable feet. The meter was scaled in degrees. Galvonometer with all brass body shell removable for initital adjustments. Two observation ports. Base with levelling feet.scientific instrument, galvonometer

The first electrical hearing aids were carbon and were made possible by the invention of the carbon microphone and were made between 1900 and 1939. Carbon, which can be made to amplify electrical current, was used to provide some amplification prior to the invention of vacuum tubes. Later models often came with mechanical (carbon) amplifiers to try to boost the amount of amplification. The carbon microphone was originally invented for use in the telephone and had the properties of being able to modulate current. It is this property that made it useful in the early electrical hearing aids. An example of a carbon hearing aid. This has an imitation tortoise shell casing. Round dark red and black imitation tortoise shell carbon hearing aid with clip for attaching to clothing, and a slide for adjusting the sound (?) a cord split between a plug and a speaker (?)."SONOTONE/REG U.S.P.A./292392/MADE IN U.S.A./ELMSFORD, N.Y." on bottom of unit.

Robin Boyd had the sound system put in by a friend who ran the iconic Thomas’ Music in the city of Melbourne. The Boyd family thinks that Robin designed the facade and logo for Thomas’ Music. Penleigh Boyd recalls "there was no 'hi-fi' record player in the living room until about 1963. Robin always had the speaker holes in the floating joinery unit but couldn’t afford the necessary equipment till years after we had moved into the house. Apparently one time some guest looked at the speaker holes (they had matchstick blind screening) and asked Robin what type of equipment he had. That was enough for Robin, and he immediately had a system installed - the one that is still there."

The Edison Fireside Phonograph Combination Type A model phonograph was an open horn model. This machine was produced around 1909, just after the introduction of 4-minute record cylinders in 1908.; the selection lever on the front was either 4 or 2-minute choice. This Fireside model has a fluted octagonal horn that attaches to the reproducer on the machine and is suspended by on ring by a horn crane attachment. The phonograph machine is powered purely by mechanical means, winding the crank handle on the side of the machine to start the belt-driven, spring-loaded motor inside. The sound comes from a pre-recorded, vertical cut record cylinder, which slides over the Mandle, a smooth rotating drum. The reproducer, an all-in-one needle, amplifier and speaker, is lowered onto the cylinder, the needle picks up the sound and plays it on the speaker and the attached horn amplifies the sound. The phonograph machine was invented by Thomas Alva Edison in the late 19th century. Edison adopted the idea from the technology of the telegraph machine. He patented the phonograph in early 1878. It was able to record sound and play it back. This amazing invention opened up a whole new world of entertainment, where wax cylinders of pre-recorded sound could be purchased with a wide variety of music and played over and over. The first wax cylinders were white and used a combination of bees' wax and animal fax or tallow. By 1892 Edison was using 'brown wax' cylinders that ranged from cream through to dark brown. The Edison Phonograph Company was formed in 1887 to produce these machines. He sold the company in 1855 to the North American Phonograph Company but bought that company in 1890. He then started the Edison Spring Motor factory in 1895, and the National Phonograph Company in 1896. In 1910 the company became Thomas A. Edison Inc. In 1898 Edison produced the Edison Standard Phonograph, the first phonograph to carry his own trade mark. He began mass producing duplicate copies of his wax cylinders in 1901 using moulds instead of engraving the cylinders. The wax was black and harder than the brown wax. The ends of the cylinders were bevelled so that the title's label could be added. The last phonograph machine to use an external open horn was produced in 1912 due to the much more robust round records being invented. In 1913 Edison started producing the Edison Disc Phonograph. The company stopped trading in 1929.This Edison Fireside Phonograph model is significant for being one of the last models to have an external horn. It is also significant for its connection with the invention of the phonograph, which made music and sound available for domestic enjoyment. It was used for entertainment and education, even teaching languages. It signalled a new era of music that could be reproduced and played anywhere. It is also significant for its short time span of popularity, just a few decades, due to the growing use of records, which gave a much higher quality sound and were more robust.Phonograph; Edison Fireside Phonograph, Combination Type, Model A. It is in a wooden case with a domed lid, metal catches on each side and a folding wooden handle. It has a metal drum and a reproducer mechanism. The metal and wood crank handle starts the machine’s motor. A sliding lever at the front selects the speed for four- or two-minute cylinders. The inscribed plate has the maker, serial number, patents and other information. The reproducer also has an inscription. It has a curved metal open horn attachment.

The phonograph is a mechanical device for the recording and reproduction of sound and originally used a tinfoil sheet wrapped around a rotating cylinder to produce the sound. It was invented by Thomas Edison of U.S.A. in 1877 and was the model for all phonographs or gramophones made and developed throughout the 20th century. This machine is of particular interest to the Warrnambool and District Historical Society as it is an Edison phonograph and an earlier model of this phonograph was used in Warrnambool late in the 19th century to make an important recording. In 1896 Thomas Rome, an employee in a Warrnambool boot and shoe shop, purchased an Edison phonograph that could both play and record sounds. At the Warrnambool Industrial and Art Exhibition of 1896-7 visitors to the Exhibition paid a fee to listen to music on this phonograph. But Rome also recorded some local Warrnambool people singing and speaking and these recordings survive today. They are regarded as the oldest surviving recordings made in Australia. Thomas Rome later became a shoe shop proprietor in Warrnambool and was a well-known person in the town/city for a great number of years. This is an Edison Gem Phonograph. It has a black-painted wooden base, now detached from the main mechanism. The phonograph is made of metal which is now heavily rusted. It has a cylindrical turntable for playing the Edison cylindrical records and a handle with a wooden knob. The turning mechanism and belt are now broken. The name of the manufacturer and details of the patents are on a metal plate attached to the side of the phonograph. The amplifier mechanism at the top of the machine is missing. The cover of the machine is made of wood and has a wooden handle attached with a piece of metal and two metal screws. There are also two metal screws on the side of the cover. The cover has a slot on the side to allow the turning handle to be accommodated outside of the cover. The cover is much stained and spotted. ‘Edison Gem Phonograph’ thomas edison, history of sound recordings, thomas rome (warrnambool)

This external horn is part of an Edison Fireside Phonograph made in c.1909. The horn was attached to the machine when in use. The rings on the side of the horn allowed the horn to be suspended above the machine. The narrow opening on the horn was attached to the sound outlet on the machine and the conical shape of the horn amplified the sound. The horn was suspended to allow a clear sound. This was done by attaching the ring fitted to the outside of the horn to a chain or chord, which in turn was attached to a curved wire fitted to the phonograph machine. The phonograph machine was invented by Thomas Alva Edison in the late 19th century. Edison adapted the idea used when sending messages over a telegraph machine. He patented the phonograph in early 1878. The phonograph was able to record sound and play it back sound.
