Filed: 1986-12-10
Abstract: PURPOSE:To improve low-pitched sound frequency reproducing capability and to reduce cost by mixing a weight material to an adhesives for bonding a voice coil and a diaphragm so as to increase the total mass of the vibration system. CONSTITUTION:A rod shape metallic material 12 is inserted in the adhesives 8 bonding the voice coil 6 and the diaphragm 7 so as to attain the weight. As the shape of the metallic material 12, it is in matching with the outer shape of the rod shaped voice coil 6 and formed as a circulararc. Since the metallic material 12 is fixed by the adhesive 8, the shape of the metallic material 12 may be in matching with the vicinity of the bonded part of the diaphragm 7 and the voice coil 6 and the accuracy of the shape of a rubber ring in a conventional speaker is not required. Thus, an advantage of the same characteristic pattern as the characteristic of the original speaker before the addition of the weight such as a rubber ring is provided and then the basic speaker design is not changed to improve the low-pitched sound reproducing capability.

Abstract: PROBLEM TO BE SOLVED: To ensure good flexuosity while lighten a weight of a hose tip end part by changing a wall thickness along an axial direction so as to enlarge an outer diameter of the inlet part side of ready-mixed concrete, and to form the outer diameter shorter toward an outlet part side continuously and intermittently. SOLUTION: A cylindrical liner surface rubber 1 is formed on a taper shape outer peripheral surface, whose inner diameter d1 is constantly formed along the total length of an axial direction, an outer diameter d2-1 of a joining side of a hose adapter is formed in a largest size in the outer peripheral surface, and the outer diameter d2-2 of an outlet part side is formed in a smallest size. The wall thickness of the inner surface rubber 1 is continuously changed along the axial direction so that the wall thickness 11 of the inlet part side is formed in a largest size and the thickness 12 of the outlet side is formed in a smallest size. Since the wall thickness is changed in order along the axial direction according to abrasion degree of each region A to E, the weight of a tip end part is reduced without reducing abrasion resistance, and a good flexuosity is ensured.
