摘要： A speaker device for use in a mobile terminal includes a speaker frame with a speaker unit mounted therein, and a frame cover provided at the rear side of the speaker frame to form a resonance space between the speaker frame and the frame cover. Sound that is output in a forward direction of the speaker unit is emitted to a front space of the speaker frame, and sound that is output to the rear of the speaker unit is emitted through the resonance space. The speaker device provides the resonance space at the rear side of the speaker frame to reinforce the output of midrange and bass tones, thereby reproducing the original sound as accurately as possible. The speaker device enables a user to enjoy vivid sound when reproducing a multimedia file or viewing a digital multimedia broadcast (DMB) program on a small-sized device, such as a mobile terminal.

摘要： To make it possible to improve a low-tone reproducing ability with a simple structure in an acoustic device including speakers in a headrest. The acoustic device includes a core material of a closed structure functioning as a core of a headrest main body, acoustic speakers 50, 50 disposed in the core material, and hollow headrest stays 15, 15 that pierce through the core material. The headrest stays 15, 15 circulate the air on the inside of the core material to the outer side via hollow sections.
