摘要： A loudspeaker radiating diaphragm can be stiffened to help increase the breakup frequency to above the working frequency range of the driver concerned, by forming it of a moulded part and an attached formed part. The moulded part is a radiating surface with stiffening ribs. The formed part is a thin surface of high modulus material, attached to the rear of the ribs. The overall structure can have significantly higher stiffness than either of the two parts. This helps in designing a loudspeaker driver that does not breakup within its working frequency range.
摘要翻译：扬声器辐射隔膜可以被加强，以通过形成模制部件和附接的成形部件来帮助将分解频率提高到相关驾驶员的工作频率范围之上。模制部件是具有加强筋的辐射表面。形成的部分是高模量材料的薄表面，附着在肋的后部。总体结构可以具有比两个部分中的任一个显着更高的刚度。这有助于设计在其工作频率范围内不会分解的扬声器驱动器。

摘要： A phase plug comprises a body having an input side for receiving acoustic waves and an output side for transmitting acoustic waves, the body including a plurality of channels extending from the input side to the output side for propagating acoustic waves through the body. The input side comprises an input surface which includes a plurality of openings constituting entrances for the channels, the input surface being substantially part of a sphere or an ellipsoid in shape. The areas of the openings vary with radial position on the input surface, the radial position being measured in a direction extending perpendicularly from a central axis extending through the input surface. The variation in the areas is a function of the cosine of an angle subtended at the centre of the sphere or a focus of the ellipsoid between the central axis and the radial position.

摘要： A side shifting and fork positioning assembly for a lift truck is disclosed. The assembly includes a carriage (2) which moves in a lift truck mast. The carriage includes a pair of horizontally spaced apart vertical members (6) and a frame support member (4) secured transversely to the vertical members. A side shift frame (20) slides on the carriage. An upper cross member (22) of the side shift frame supports two forks (5) along their hook portion. Hydraulically actuated cylinders (12, 14) located in the frame support member move the side shift frame. The assembly also includes first and second fork shoes (40a, 40b) movably secured to the side shift frame. Each of the fork shoes define a contact surface to engage the forks. The contact surface of the fork shoes is located no further forward than a front face of the upper cross member. The assembly includes a fork positioner (3) which moves the first fork shoe relative to the second fork shoe, where the fork shoes are maintained at an equal distance from the center of the side shift frame.
