ABSTRACT:
A vibration isolating mounting arrangement for a sound accessory for a motion picture viewer is provided. The mounting arrangement includes an accessory mounting plate which precisely engages a portion of the viewer for locating the plate with respect to a film cassette receiving well in the top of the viewer. An audio component arrangement is provided which includes an audio transducer and means for advancing the audio tape past the transducer. These audio components are mounted to an audio component plate which is supported in overlying relationship with respect to the accessory mounting plate and the audio components carried thereby. The mounting between the two parallel plates is designed to effect vibration isolation between the plates, thus isolating the audio components carried by the upper plate from vibrations present in the viewer during its operational modes.
