A video display device includes a video display panel that displays video, a case that encloses an outer periphery of the video display panel, an audio device that is arranged in proximity to the outer periphery of the video display panel, the audio device being configured to linearly arrange a plurality of speakers, and a sound emitting hole that corresponds to an opening of the audio device, the sound emitting hole being provided to the case and emitting sound generated by the audio device.

Video display device

A loudspeaker includes a back panel and a plurality of thin loudspeakers mounted onto the back panel. The back panel has an aspect ratio of 6 or higher, and has a wiring unit formed thereon and wire-connecting the thin loudspeakers. The thin loudspeakers are arranged on the back panel in series in a straight line. Accordingly, a thin-type loudspeaker can be realized.

Loudspeaker, electronic apparatus using same, and mobile apparatus

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.
