Abstract: A juice extracting cup used in a juice extractor comprises a cup body and a filter net. The cup body is hollow and has openings at two ends and several longitudinal ribs projected from inner wall. A supporting strip along the inner wall of the cup body is projected from the inner wall below the several ribs. The filter net is disposed inside the body cup, and several clip strips are projected at the bottom end of outer wall of the filter net. Several openings correspond to the several ribs between every two clip strips, and each of the several openings hosts the respective rib. The several clip strips are clipped between bottom ends of the several ribs and the supporting strip. The juice extracting cup used in the juice extractor according to the present invention can effectively prevent the filter net from falling off and thus the effect of juice extracting can be guaranteed.

Abstract: A sound effect sensing turntable for a digital music broadcaster includes a capacitive charge sensing plate able to independently detect the variation of charge. A signal transmission unit is disposed between the sensing plate and a control plate for transmitting signals and thus, on receiving a signal, the control plate will produce relative sound effect to be output.
