摘要： The present invention relates to a multi-function actuator, in which a voice coil vibrates a sound-generating diaphragm in response to an audio signal. A vibration coil is placed on a central axis coaxial with the voice coil for generating vibration in response to the audio signal or a vibration signal. A vibration unit includes a magnet for generating a magnetic field to both of the voice coil and the vibration coil and a yoke having a predetermined mass. The vibration unit is vertically vibrated by an electromagnetic force produced from at least one of the voice coil and the vibration coil. A switch selectively applies the audio signal to the vibration coil. The multi-function actuator can prevent the vibration of the vibration unit during sound generation in response to user's switch selection.

摘要： A wafer level fan out semiconductor device and a manufacturing method thereof are provided. A first sealing part is formed on lateral surfaces of a semiconductor die. A plurality of redistribution layers are formed on surfaces of the semiconductor die and the first sealing part, and solder balls are attached to the redistribution layers. The solder balls are arrayed on the semiconductor die and the first sealing part. In addition, a second sealing part is formed on the semiconductor die, the first sealing part and lower portions of the solder balls. The solder balls are exposed to the outside through the second sealing part. Since the first sealing part and the second sealing part are formed of materials having thermal expansion coefficients which are the same as or similar to each other, warpage occurring to the wafer level fan out semiconductor device can be suppressed.
