An improved fire-blocking gasket profile for a fire-rated joint, such as a head-of-wall assembly. Fire-rated joints are aimed at inhibiting or preventing fire, heat, or smoke from leaving one portion of a building and entering another portion of a building. Fire-rated joints can also accommodate movement between adjacent building structures, such as between a ceiling and the top of a wall. The improved fire-blocking gasket profile includes a first layer formed of an intumescent material, a second layer formed of a foil lining and a third layer formed of the vinyl profile. The vinyl profile includes an air gap with the intumescent material positioned therein. A vertical portion of the vinyl profile is positioned between a header track and a wallboard in the fire-rated joint. A horizontal portion of the vinyl profile is positioned at least partially within a deflection gap and sealingly engages with the ceiling.

Disclosed are a vibrating diaphragm for a sound generating device, a method for preparing the vibrating diaphragm, and a sound generating device. The vibrating diaphragm comprises at least one modified thermoplastic polyester elastomer layer, wherein a modifier is involved which is at least one of a temperature: resistant resin, an inorganic filler and an anti-aging agent, and the modifier is added to a themoplastic polyester elastomer material. In an embodiment of the present invention, by adding the modifier to the themoplastic polyester elastomer material and sufficiently mixing the modifier when making a film layer, the aim of improving the temperature resistance of a moulded vibrating diaphragm is achieved.

A profile element is useful for sealing building-structure joints, especially for sealing against sound and smoke and optionally against fire. An apparatus is useful for manufacturing such profile element and to the use of the profile element manufactured according to the invention for the acoustic, smokeproof and/or fireproof sealing of connecting joints in drywalls, especially of expansion joints.
