A method of molding a toner bottle including separating polyethylene terephthalate (PET) bottles that have not accommodated oily or colored materials from retrieved PET bottles grinding the separated PET bottles to obtain a flake PET material of which not less than 80% has a form from a triangle to an octagon with a size not greater than 8 mm 8 mm, washing and drying the flake PET material to obtain a flake PET molding material and molding the flake PET molding material to make a toner bottles.

Method of molding a toner bottle using up to 8-sided recycled flake

Speaker box

A speaker system has a first baffle (2) supporting a first speaker unit for producing sounds in a first frequency range (low frequencies), at least one second baffle (27L), (27R) supporting a second speaker unit for producing sounds in a second frequency range which is higher than the first frequency range (middle and/or high frequencies), the second baffles (27L), (27R) being smaller than the first baffles (2). The second baffle (27L), (27R) are spaced a predetermined distance from the first baffle (2). The speaker system has a reduced baffle effect, and increases direct sounds radiated directly from the speaker units, as compared with indirect sounds radiated backwards from a baffle, thereby improving frequency characteristics in the middle frequencies and providing excellent sound image localization.
