Abstract
(EN)
An electronic apparatus may include a loudspeaker that includes an enclosure; a first driver disposed in the enclosure and configured to output a sound based on an input audio signal; a unit accommodator having a hole in which the first driver is disposed, and extending toward an inside of the enclosure; a space forming portion extended from an outer edge of the unit accommodator, surrounding a back of the first driver to form a space with the unit accommodator, and spaced apart from an inner edge of the unit accommodator; a slot forming portion extending from the space forming portion, and having an inner surface spaced apart from an outer surface of the unit accommodator to form a first sound output passage; and a sound absorber disposed at at least one of the outer surface of the unit accommodator and the inner surface of the slot forming portion.
