The driving system of the speaker is constructed by a circular PZT bimorph, which is clamped on its boundary, An elastical coupling element is utilized between the bimorph and the speaker cone.
The use of the second collection optic 406 to reduce the cone Angle of the light that passes through the wavelength converting element 110 improves the performance of the second dichroic filter 408.
