Sounder the simplest telegraph apparatus for the audible reception of Morse code. It is an electromagnet with two coils and an armature, which is restrained by a coil spring. The range of deflection of the armature lever is limited by screws. The telegraph operator hears the knocking of the lever against the screws. To amplify the sound, the sounder is placed in an acoustic resonator. Sounders were used with Morse apparatus in the late 1920’s and early 1930’s; however, they did not become widespread, since they do not provide a record of the signals. sounder Related to sounder: depth sounderWords related to soundernoun a device for making soundingsRelated Words |
