Abstract: The present invention relates to a textured yarn (ATY) with different shrinkage and excellent suede effect, wherein at least one or two kinds of two-component composite yarn (effect) yarn having a monofilament fineness are twined around a thermoplastic multifilament yarn (core yarn), forming loops on the surface of the textured yarn.

Abstract: The present invention relates to a textured yarn (ATY) with different shrinkage and excellent suede effect, wherein at least one or two kinds of two-component composite yarns (effect yarn) having a monofilament fineness of 0.001 to 0.3 denier after dividing or extracting an extraction component are twined around a thermoplastic multifilament yarn (core yarn), 2 to 350 loops per meter of the two-component composite yarn of at least 1.0§® in length are formed on the surface of the textured yarn, and more than 95% of the two-component composite yarn loops of at least 1.0§® in length has a length of 1.0 to 2.5§®. The present invention prepares the textured yarn with different shrinkage by air-texturing the two-component composite yarn (effect yarn) and the thermoplastic multifilament yarn (core yarn) in an air texturing nozzle under the condition that the overfeed ratio of effect yarn to core yarn is 1.2 to 4.0.

Abstract: A body speaker comprising a casing having an upper part and a lower part; the upper part has a central circular aperture closed by a cap, a thin magnetic disk with a small diameter centrally attached on the inside of the cap, a tubular member fixed around the central circular aperture of the upper part, a solenoid coil wound around the tubular member. An oscillation body is disposed between the upper and lower parts for oscillating in response to variation of the magnetic field of the solenoid coil. Gaps are provided in an assembled configuration of the upper and lower parts, between the upper and lower surfaces of the oscillation body and the inside surfaces of the upper and lower parts of the casing when the oscillation body is fixed on the inside wall of the casing by means of an oscillation ring, so that the oscillation body may freely oscillate upwards and downwards in response to variation of the magnetic field of the solenoid coil conducting current.
