(Mi"cro*phone) n. [Micro- + Gr. sound, voice: cf. F. microphone.] (Physics) An instrument for intensifying and making audible very feeble sounds. It produces its effects by the changes of intensity in an electric current, occasioned by the variations in the contact resistance of conducting bodies, especially of imperfect conductors, under the action of acoustic vibrations.

(Mi`cro*phon"ics) n. [See Microphone.] The science which treats of the means of increasing the intensity of low or weak sounds, or of the microphone.

(Mi*croph"o*nous) a. Serving to augment the intensity of weak sounds; microcoustic.

(Mi`cro*pho"to*graph) n. [Micro- + photograph.]

1. A microscopically small photograph of a picture, writing, printed page, etc.

2. An enlarged representation of a microscopic object, produced by throwing upon a sensitive plate the magnified image of an object formed by a microscope or other suitable combination of lenses.

A picture of this kind is preferably called a photomicrograph.

(Mi`croph*thal"mi*a Mi`croph*thal"my) n. [Micro- + Gr. 'ofqalmo`s eye.] An unnatural smallness of the eyes, occurring as the result of disease or of imperfect development.

(Mi"cro*pyle) n. [Micro- + Gr. gate, orifice: cf. F. micropyle.] (Biol.) (a) An opening in the membranes surrounding the ovum, by which nutrition is assisted and the entrance of the spermatozoa permitted. (b) An opening in the outer coat of a seed, through which the fecundating pollen enters the ovule.Mi*crop"y*lar a.

(Mi*cros"co*pal) a. Pertaining to microscopy, or to the use of the microscope. Huxley.

(Mi"cro*scope) n. [Micro- + -scope.] An optical instrument, consisting of a lens, or combination of lenses, for making an enlarged image of an object which is too minute to be viewed by the naked eye.
