Abstract: The invention discloses an oscillating lens module and a projector. The oscillating lens module includes a frame, a first coil, a lens, and a second coil. The first coil and the second coil are connected to the frame and located in a magnetic field, wherein the first coil and the second coil are adapted to be electrified and to oscillate about a first axis and a second axis respectively via the magnetic field. The lens is connected to the first coil, wherein the lens is adapted to oscillate along with the first coil. An oscillation phase of the second coil is opposite to an oscillation phase of the first coil, such that forces applied on the frame by the first coil and the second coil are counterbalanced, so as to prevent the oscillating lens module from over vibrating which makes projection images shake and makes noise.

Abstract translation: 本发明公开了一种振荡透镜模块和投影仪。 振荡透镜模块包括框架，第一线圈，透镜和第二线圈。 第一线圈和第二线圈连接到框架并且位于磁场中，其中第一线圈和第二线圈适于通电并且经由磁场分别围绕第一轴线和第二轴线摆动。 透镜连接到第一线圈，其中透镜适于与第一线圈一起振荡。 第二线圈的振荡相位与第一线圈的振荡相位相反，使得由第一线圈和第二线圈施加在框架上的力被抵消，以防止振动透镜模块过度振动，从而使投影 图像抖动并产生噪音。

Abstract: A wavelength conversion module and a projection device are provided. The wavelength conversion module includes a rotating member and a light sensing element. The rotating member includes a shaft and a positioning structure. An excitation beam forms a first spot on the rotating member. The shaft is located at the center of the rotating member. The positioning structure is located on the rotating member. The light sensing element is disposed adjacent to the rotating member for emitting a sensing beam toward a first surface of the rotating member, wherein the sensing beam forms a second spot on the rotating member. A first connecting line is formed by connecting the first spot and the shaft, a second connecting line is formed by connecting the second spot and the shaft, and an angle between the first connecting line and the second connecting line is greater than 30 degrees.

Abstract: A noise-reducing fan system, comprising a motor, a fan body, a plurality of magnetic-inducing elements, a magnetic field generator and a noise-reducing sound source device, is provided. Here, the fan body is mounted on the motor. The fan body comprises a plurality of blades, on which the plurality of magnetic-inducing elements are disposed, respectively. The magnetic field generator, which may generate a magnetic field, is employed for driving the plurality of magnetic-inducing elements to vibrate the plurality of blades and generate a vibration sound, so that at least one portion of the noise emitted from the fan body as rotating may be counterbalanced. The noise-reducing sound source device is disposed on a predetermined position and may send out a noise-reducing sound, so that the noise-reducing sound may counterbalance at least the other portion of the noise emitted from the fan body as rotating.
