摘要： The present invention relates to a hybrid magnet engine valve actuator. Especially, the hybrid magnet engine valve actuator drives a valve bar of a non-magnet material for opening an intake and exhaust valve. The hybrid magnet engine valve actuator comprises an upper yoke installed above a lower yoke; a coil which is wrapped over the outer surface of the upper yoke to generate a variable magnet field with certain intensity and direction according to the supply direction and voltage supplied from outside; and a shorted turn which is installed between the upper yoke and the coil to reduce time for generating the variable magnet field by promoting the increase of the voltage when the voltage is applied to the coil. As the shorted turn is added between the upper yoke and the coil, the effective inductance generating at the beginning of applying the voltage to the coil is reduced so that time for opening and closing an engine valve is reduce by slowing down the speed of increasing current. The hybrid magnet engine valve actuator is capable of maximizing the speed of an engine by obtaining variable valve timing in the faster rotary speed of the engine.

摘要： The present invention relates to a horizontal-type linear vibration motor. More specifically, in the disclosed horizontal-type linear vibration motor for a mobile phone, an elastic member includes: a rectangular horizontal plate which has a certain volume; a pair of flat springs which are curved in one body at a certain angle in the opposite directions to each other at the front and the rear ends of both lateral surfaces of the horizontal plate and are elastically deformed in the horizontal direction in a cantilever form individually; and a pair of horizontal welding fixing plates which are curved in one body towards the horizontal plate on the top and the bottom surface of each end of the flat springs to fix the ends of the flat springs onto the ceiling surface of a case and onto the top surface of a bracket individually through welding. Therefore, the elastic member itself can maintain the state of being fixed in one body between the ceiling surface of the case and the top surface of the bracket. At the same time, the repetitive vibration force from a vibrator can be prevented from being directly delivered to the welding part and accordingly cracks or damage to the welding part of the flat springs due to the repetitive vibration force from the vibrator can be completely prevented. Also, since the vibrator vibrates while being stably supported, the vibration performance can be improved. Furthermore, by using the elastic member in which the inclined or V-shaped flat springs are curved in one body on the both surfaces of the horizontal plate, processing and manufacturing becomes easy.
摘要翻译：本发明涉及水平式线性振动电动机。更具体地，在所公开的用于移动电话的卧式线性振动电动机中，弹性构件包括：具有一定体积的矩形水平板; 一对扁平弹簧，其在水平板的两个侧表面的前端和后端以相反方向以一定角度弯曲成一体，并且在水平方向上以单独的悬臂形式弹性变形 ; 以及一对水平焊接固定板，它们在板簧的每一端的顶表面和底表面上朝着水平板弯曲成一体，以将平板弹簧的端部固定在壳体的天花板表面上支架的上表面通过焊接单独进行。因此，弹性构件本身可以将壳体的顶板表面和支架的顶面之间的一体固定的状态保持在一起。同时，可以防止来自振动器的重复振动力直接传递到焊接部分，从而可以完全防止由于来自振动器的重复振动力而导致的板簧的焊接部分的裂纹或损坏。此外，由于振动器在稳定地被支撑的同时振动，因此可以提高振动性能。此外，通过使用在水平板的两个表面上的倾斜或V形扁平弹簧在一个主体中弯曲的弹性构件，加工和制造变得容易。
