Abstract: Shock isolation mounts for miniature microphones, sound reproducers, and other fragile devices, in which the device is suspended between thin film support members mounted on a rigid frame in a configuration such that shock stresses of substantial magnitude occurring in either direction along a given path are absorbed almost entirely by tensional stress of one or more of the film support members. Vibration isolation is also provided, separately from the shock isolation, by means of one or more vibration absorption elements, formed of rubber or other material of high resilience and high compliance in compression, interposed between the fragile device and support members or between the support members and the frame or between the frame and an external support structure. The support members are usually made of plastic, such as a polyester film, and may be pre-formed to fit the external configuration of the transducer or other device or may be flat strips with no pre-forming required.
