  • Speaker system, electronic apparatus using same, and mobile body device
    Patent number: 8818006
    Abstract: A loudspeaker system includes an enclosure surrounding a plurality of loudspeakers. The plurality of loudspeakers are disposed in series along a straight line in the enclosure. The enclosure includes a front panel, a back panel and side panels. The front panel, the side panels, and the back panel are disposed parallel to the straight line on which the loudspeakers are arranged. The side panels are provided with a front slit and a back slit. The back slit is disposed at an opposite side of the front slit in the enclosure. Sounds emitted to the upper and lower sides of diaphragms of the loudspeakers are separated from each other such that the sounds are prevented from mixing with each other. This provides a loudspeaker system capable of achieving desired sound pressure-frequency characteristics.
