Abstract
An electro-acoustic transducer assembly includes a permanent magnet and a diaphragm having a voice coil bonded thereto. The assembly comprises a hollow casing having an opening formed in one surface thereof; a closure for covering the opening and comprising an aperture therein in which the diaphragm is mounted, and a cover mounted on one side of the closure for protecting the diaphragm, wherein the magnet is positioned on the opposite side of the closure in proximity to the voice coil on the diaphragm. The assembly also includes a latching assembly for releasably securing the closure across the opening in the casing in a latched position with the cover being positioned to the exterior of the assembly and the magnet being positioned in the casing, the latching assembly being operable by application of pressure at preselected locations on the periphery of said casing to release the closure from the latched position. The closure is elastically biased away from the opening of the casing upon release of the closure from the latched position, upon application of the pressure.
