Title:
SPEAKER SYSTEM, AND SPEAKER CLUSTER SYSTEM
Document Type and Number:
WIPO Patent Application WO/2005/117484
Kind Code:
A1
Abstract:
A speaker system may be desired to acquire a fixed directivity over a frequency range as wide as possible. However, a speaker system using a horn of a fixed directivity is frequently used in combination with a box speaker having a built-in woofer unit. This system is large-sized. Another desire is to acquire the fixed directivity in a lower frequency. The speaker system (10) is provided with an enclosure (20), a first speaker unit (30) for a low range, and a plurality of second speaker units (31, 32 and 33) for a high range. The enclosure (20) has a front plate unit (21) as a baffle plate and a rear plate unit (22). The length of the rear plate unit (22) along a first direction perpendicular to the longitudinal direction is shorter than that of the front plate unit (21) along the first direction. The first speaker unit (30) and the second speaker units (31, 32 and 33) are mounted on the front plate unit (21). The second speaker units (31, 32 and 33) are juxtaposed along the first direction. The second speaker units (31, 32 and 33) have their diaphragms positioned near the front plate unit (21) in the longitudinal direction.
