<p>PROBLEM TO BE SOLVED: To provide a flat speaker good in design, high in sound quality, causing no blurs of a screen, and driven by a piston motion mode without affecting picture quality, in a flat speaker for a display such as a flat panel television set.SOLUTION: A diaphragm 1 and a fixing (adhesive) cushion 2 are fixed to a housing 5 of a television set (such as a display) with an adhesive. L-shaped (U-shaped) metal 3 is bonded to an edge of the diaphragm 1. The L-shaped (U-shaped) metal 3 is directly vibrated by a vibration vocalization unit (actuator) 4, thereby causing piston movements in the diaphragm 1.</p> |
