Abstract: A conductive wire, coil, and device, wherein in the conductive wire, an aluminum oxide-coated graphene is added to a first paint layer, and a silver-coated graphene is added to a second paint layer. By means of such an arrangement, the coefficient of thermal conductivity of the first paint layer and the second paint layer reaches 2 to 10 W/(m·K), and therefore, the thermal conduction performance of the conductive wire can be remarkably improved, and the thermal conduction wire has an advantage of a good thermal conduction effect, with timely heat dissipation.

Abstract: The present disclosure provides a diaphragm and a sound generating device using the diaphragm. The diaphragm comprises a diaphragm body part, and a composite layer bonded to the center of the diaphragm body part. The composite layer comprises: a porous material layer; and a first metal layer and a second metal layer respectively disposed on two sides of the porous material layer. Compared with the prior art, the composite layer of the diaphragm adopts a composite structure composed of a porous material layer and metal layers, which can reduce the mass of the diaphragm and improve the modulus density ratio of the diaphragm while ensuring the rigidity of vibration. The porous structural material can increase the damping of the diaphragm, absorb the vibration energy under the specific resonant frequency, and thus effectively improve the high-frequency split vibration, reduce the distortion and improve the high pitched sound quality.
