Product Description

Sound film material

The sound is converted from electricity, displacement, pressure and other signals into vibration signals, which must be realized through the diaphragm. A good diaphragm material should have comprehensive properties such as low density, high strength, high stiffness, high vibration transmission speed and suitable vibration internal loss. Magnesium alloy diaphragm material has low density, good rigidity, moderate damping, and its density and specific modulus are obviously better than that of aluminum, stainless steel, titanium and other metal materials.

The thickness of our ultra-light magnesium-lithium alloy foil coil is only 0.014mm. The coil method is adopted to optimize the composition design of magnesium-lithium alloy to control the density of magnesium-lithium alloy and improve its processing performance. Magnesium-lithium alloy specific damping coefficient and internal friction The coefficient is higher, which is beneficial to the energy dissipation in the sound vibration process, improves the stability of the equipment, and can achieve high fidelity in the application of audio.

On January 8-11, 2019, the company's new magnesium-lithium alloy foils were used by customers. The new audio products processed by the company were unveiled at the International Consumer Electronics Show in Las Vegas, USA, and the weight was reduced by about half. , The overall sensitivity has increased by 1.5 to 2db, which was praised by participants and experts unanimously, and demonstrated the superiority of magnesium-lithium alloy audio diaphragm to customers around the world.
