    摘要: The invention relates to a thermotropic sound production device comprising a thermotropic sound production element which is laid and is electrically connected to at least one first electrode and at least one second electrode; a heat reflection element is arranged at one side of the thermotropic sound production element at interval, and the thermal emissivity of the heat reflection element is 30% more than the reflectivity of infrared light. The thermotropic sound production device provided by the invention is characterized in that one side of the thermotropic sound production element is provided with one heat reflection element to cause the heat irradiation of the thermotropic sound production element to emit directionally, so that heat reflection to the element arranged on one side of the heat reflection element which deviates from the thermotropic sound production element, is reduced.

    摘要: A method for making a carbon nanotube film is provided. In the method, a carbon nanotube array is grown on a substrate, and a rigid drawing device is provided. The carbon nanotube array is adhered to the rigid drawing device via an planar adhesive region of the rigid drawing device. The rigid drawing device is pulled at a speed along a direction away from the substrate, thereby pulling out a continuous carbon nanotube film. The carbon nanotube array includes a plurality of carbon nanotubes. The planar adhesive region have a linear border, wherein the linear border of the planar adhesive region is the closest border of the planar adhesive region to a surface of the substrate. The carbon nanotubes in the carbon nanotube array are adhered via the planar adhesive region.
