Loudspeaker diaphragm

A speaker diaphragm 10 is provided having an improved quality of radiation sounds and a good outer appearance. The speaker diaphragm has in its slanted area projections typically represented by a peak line 4 and recesses typically represented by a bottom line 5. The projection typically represented by the peak line extends radially from the central area to the edge portion, and curves along the circumferential direction as it comes near to the edge portion. While the speaker diaphragm 10 vibrates at a large amplitude and moves toward the bottom side thereof, a rotation force is applied to air which is likely to concentrate upon the central area to thereby lower the air pressure to the central area. The speaker diaphragm 10 has a three-dimensional structure like a screw propeller so that the mechanical strength of the speaker diaphragm 10 can be increased over the whole area thereof and division vibrations can be suppressed. The speaker diaphragm is manufactured by ejection molding of material containing polypropylene as it main composition so that a variety of colors can be easily used during manufacture processes. In cooperation with the unique structure like the screw propeller, a strong visual impression is given.

Provided is an infrared image ME noise removal method based on on-orbit classification statistics. An ME detection template traverses a whole-scene image to detect ME noise based on radiation information carried by a satellite image, and the detected ME noise is removed by an iterative method, which makes up for the drawback of a system impulse response function. Given that the forms of ME noise have different characteristics at different radiances of an infrared image, an idea of classification is introduced in the method, and ME noise at different radiances is removed by different approaches. Finally, residual stripe noise of the image after processing is removed by adaptive moment matching so as to further improve the quality of radiation of the infrared image.

The invention discloses a method for measuring relative radiance of large-scanning angle sliding spotlight SAR satellite systems. The method comprises the steps of: selecting a uniform scattering scene as an imaging area; carrying out imaging and range attenuation correction on echo data to obtain single-looking complex image data; getting rid of non-uniform scattering area in the image so as to eliminate adverse effect of subsequent relative radiance measurement; smoothing the image by utilizing a certain rectangular window so as to reduce the noise influence and obtain an amplitude image; averaging multiple images with same beam positions to further reduce the noise influence; determining an azimuth angle and a lower visual angle corresponding to each pixel of the smoothed amplitude image according to radar parameters such as an azimuth scanning range, a range beam width and the like of radar; and carrying out even-order tow-dimensional surface polynomial fitting on the smoothed amplitude image by taking the azimuth angle and the lower visual angle as variables, so as to obtain relative radiance of a system. By utilizing the method, high-precision measurement results for relativeradiance of large-scanning angle sliding spotlight SAR satellite systems can be effectively obtained, so that the method can be used for relative radiation correction of the systems so as to improvethe image quality.
