Vibration (n.) A limited reciprocating motion of a particle of an elastic body or medium in alternately opposite directions from its position of equilibrium, when that equilibrium has been disturbed, as when a stretched cord or other body produces musical notes, or particles of air transmit sounds to the ear. The path of the particle may be in a straight line, in a circular arc, or in any curve whatever..

Reed :: Reed (n.) One of the thin pieces of metal, the vibration of which produce the tones of a melodeon, accordeon, harmonium, or seraphine; also attached to certain sets or registers of pipes in an organ..
Shake :: Shake (v.) To cause to move with quick or violent vibrations; to move rapidly one way and the other; to make to tremble or shiver; to agitate.
Escapement :: Escapement (n.) The contrivance in a timepiece which connects the train of wheel work with the pendulum or balance, giving to the latter the impulse by which it is kept in vibration; -- so called because it allows a tooth to escape from a pallet at each vibration..
Harmonicon :: Harmonicon (n.) A small, flat, wind instrument of music, in which the notes are produced by the vibration of free metallic reeds..
Resonance :: Resonance (n.) A prolongation or increase of any sound, either by reflection, as in a cavern or apartment the walls of which are not distant enough to return a distinct echo, or by the production of vibrations in other bodies, as a sounding-board, or the bodies of musical instruments..
Pitch :: Pitch (n.) The relative acuteness or gravity of a tone, determined by the number of vibrations which produce it; the place of any tone upon a scale of high and low..
Sonometer :: Sonometer (n.) An instrument for exhibiting the transverse vibrations of cords, and ascertaining the relations between musical notes. It consists of a cord stretched by weight along a box, and divided into different lengths at pleasure by a bridge, the place of which is determined by a scale on the face of the box..
Sound :: Sound (n.) The occasion of sound; the impulse or vibration which would occasion sound to a percipient if present with unimpaired; hence, the theory of vibrations in elastic media such cause sound; as, a treatise on sound..
Agraffe :: Agraffe (n.) A hook, eyelet, or other device by which a piano wire is so held as to limit the vibration..
Larynx :: Larynx (n.) The expanded upper end of the windpipe or trachea, connected with the hyoid bone or cartilage. It contains the vocal cords, which produce the voice by their vibrations, when they are stretched and a current of air passes between them. The larynx is connected with the pharynx by an opening, the glottis, which, in mammals, is protected by a lidlike epiglottis..
Phonograph :: Phonograph (n.) An instrument for the mechanical registration and reproduction of audible sounds, as articulate speech, etc. It consists of a rotating cylinder or disk covered with some material easily indented, as tinfoil, wax, paraffin, etc., above which is a thin plate carrying a stylus. As the plate vibrates under the influence of a sound, the stylus makes minute indentations or undulations in the soft material, and these, when the cylinder or disk is again turned, set the plate in vibration
Zoospore :: Zoospore (n.) A spore provided with one or more slender cilia, by the vibration of which it swims in the water. Zoospores are produced by many green, and by some olive-brown, algae. In certain species they are divided into the larger macrozoospores and the smaller microzoospores. Called also sporozoid, and swarmspore..
Undulation :: Undulation (n.) The act of undulating; a waving motion or vibration; as, the undulations of a fluid, of water, or of air; the undulations of sound..
Wave :: Wave (v. i.) A vibration propagated from particle to particle through a body or elastic medium, as in the transmission of sound; an assemblage of vibrating molecules in all phases of a vibration, with no phase repeated; a wave of vibration; an undulation. See Undulation..
Voiced :: Voiced (a.) Uttered with voice; pronounced with vibrations of the vocal cords; sonant; -- said of a sound uttered with the glottis narrowed.
Phonoscope :: Phonoscope (n.) An instrument for producing luminous figures by the vibrations of sounding bodies.
Stylus :: Stylus (n.) That needle-shaped part at the tip of the playing arm of phonograph which sits in the groove of a phonograph record while it is turning, to detect the undulations in the phonograph groove and convert them into vibrations which are transmitted to a system (since 1920 electronic) which converts the signal into sound; also called needle. The stylus is frequently composed of metal or diamond..
Damper :: Damper (n.) That which damps or checks; as: (a) A valve or movable plate in the flue or other part of a stove, furnace, etc., used to check or regulate the draught of air. (b) A contrivance, as in a pianoforte, to deaden vibrations; or, as in other pieces of mechanism, to check some action at a particular time..
Nonconductor :: Nonconductor (n.) A substance which does not conduct, that is, convey or transmit, heat, electricity, sound, vibration, or the like, or which transmits them with difficulty; an insulator; as, wool is a nonconductor of heat; glass and dry wood are nonconductors of electricity..
Phase :: Phase (n.) Any one point or portion in a recurring series of changes, as in the changes of motion of one of the particles constituting a wave or vibration; one portion of a series of such changes, in distinction from a contrasted portion, as the portion on one side of a position of equilibrium, in contrast with that on the opposite side..
