By removing the cap from the receiver the shell is screwed into a receptacle on the end of the loud speaker and the instrument is ready for use. A Super Loud Speaker. This loud speaker, which is known as the Magnavox Telemegafone, was the instrument used by Lt.
World's Largest Loud Speaker ever made. Either kind may be used with a one- or two-step amplifier or with a cascade of half a dozen amplifiers, according to the degree of loudness desired. The Telemegafone itself is not an amplifier in the true sense inasmuch as it contains no elements which will locally increase the incoming current.
It does, however, transform the variable electric currents of the wireless receiving set into sound vibrations in a most wonderful manner. A telemegafone of either kind is formed of: a telephone receiver of large proportions, a step-down induction coil, and a 6 volt storage battery that energizes a powerful electromagnet which works the diaphragm.
In this way then are the faint incoming signals, speech and music which are received by the amplifying receiving set reproduced and magnified enormously. The Telemegafone is shown complete at B. From the foregoing chapters you have seen that the vacuum tube can be used either as a detector or an amplifier or as a generator of electric oscillations, as in the case of the heterodyne receiving set.
