Background The loudspeaker diaphragm is a core component for converting an electric signal into mechanical vibration and pushing air to generate sound waves, and is usually made of a light and high-rigidity material (such as paper pulp compound, polypropylene, carbon fiber, titanium alloy or silk membrane), one end of the loudspeaker diaphragm is rigidly connected with a voice coil, the other end of the loudspeaker diaphragm is fixed on a frame through a folding ring and elastic waves, lorentz force is generated in a magnetic field of a permanent magnet when audio current passes through the voice coil, and the diaphragm is driven to reciprocate back and forth, so that the surrounding air is periodically compressed and thinned, and sound wave radiation is formed. The rigidity of the vibrating diaphragm determines the stability of high-frequency response, the damping characteristic influences the attenuation speed of medium-low frequency, the light weight promotes transient response and detail restoring capability, and the material and structural design directly determine the definition, dynamic range and distortion level of sound quality, thus being the only terminal element for realizing the electro-magnetic-force-acoustic energy conversion in the whole electroacoustic system.
