PURPOSE:To provide a thin speaker by installing several pieces of sound elements on one side of a baffle board which has a common pivot and can be folded freely, and supplying input signals for the speaker to each of those sound elements. CONSTITUTION:The baffle board 1 is consists of metal, wood, plastic and other appropriate materials, and has a mounting plate and protective plate or carrying case of the speaker for common use. It constitutes a hollow plate on which speaker element slots 7 corresponding to the mounting positions of the sound elements 2 are formed. The sound elements 2 are the ones for a plate piezoelectric type micro speaker or magnet type micro speaker of about 5 to 10mm in diameter and 0.2 to 0.5mm in thickness. They are mounted to the positions corresponding to the speaker element slots 7 on hollow part of the baffle board 1, shown in the figure, by an existing gluing means usch as bonding material. |
