The rubber layer is prepared by crosslinking of a rubber material and a vulcanizing agent, and includes, by weight, 100 parts of ethylene-acrylate rubber, 0-100 parts of nano filler, 1-8 parts of the vulcanizing agent, 0.2-6 parts of an anti-aging agent and 1-10 parts of an internal releasing agent. A sound-generating device including the diaphragm is provided. Through the multi-layer composite structure, the loss factor peak of the composite diaphragm in the dynamic mechanical analysis is widened, and the loss factor is maintained at a higher level within a range from ?10° C. to high temperature, greatly improving the damping property. The use of the composite diaphragm in sound-generating devices can effectively improve the acoustic performance and reduce the total harmonic distortion, enabling better acoustic restoration effects.

Abstract: A firearm system includes a firearm and a user identification system built-in with the firearm. The user identification system includes a locking module that releasably locks up a trigger-actuated firing mechanism of the firearm from being actuated, a camera module being activated for generating tangible evidence of operation incidents, and an activation module operatively linked to the locking module. The activation module pre-stores authorized user data and continuously collects user operation data not only to activate the camera module for capturing image but also to actuate the locking module to unlock the trigger-actuated firing mechanism when the authorized user data is matched with the user operation data. Once the authorized user data is not match with the user operation data, the trigger-actuated firing mechanism is instantaneously locked to prevent an unauthorized usage of the firearm.
