Abstract
A speaker device includes a speaker that outputs sound, a horn that emits sound output from the speaker, and a slit opening that is formed on a front surface of the horn, a vertical side of the slit opening being longer than a horizontal side of the slit opening. It is possible to prevent reflection of unnecessary sound in a vertical direction and enhance sound reproduction performance in a horizontal direction.
