摘要： A screen speaker system (10) includes a screen (12) for projecting a video by a projector and drives the screen (12) to emit audio from the screen (12). The screen speaker system (10) further includes a drive body (50) for driving the screen (12) and at least one piezoelectric element (70) for driving the screen (12) and performing reproduction at a high frequency band than a reproduction frequency band in the drive body (50). It is possible to increase the reproduction frequency band of the screen speaker system without significantly changing the structure.

摘要： A diaphragm of an optical-acoustic transducer, which improves placement and a shape of a suspension in a cantilever form, and is compact with high performance and suitable for mass production, is provided. In the optical-acoustic transducer in which a light emitter and a light receiver are placed to oppose to a reflecting portion formed on a vibrating section of a diaphragm constructed by connecting the vibrating section and a supporting portion with cantilevers, light is irradiated to the reflecting portion from the light emitter, and a reflected light from the reflecting portion is received with the light receiver to detect a position of the vibrating section, the cantilevers are formed by performing slit working for the diaphragm, portions between an outer circumference edge of the vibrating section and inner circumference edges of the cantilevers and portions between an inner circumference edge of a supporting portion and outer circumference edges of the cantilevers are partitioned by the slit working, and the cantilevers extend along an outer circumference of the vibrating section.

摘要： A displacement/quantity of light converter in which sensitivity to a micro displacement due to sound of a diaphragm, or the like, can be enhanced easily. In the displacement/quantity of light converter where a light emitting part (2) and a light receiving part (3) are disposed oppositely to a diaphragm (1), light emitted from the light emitting part (2) and reflected off the diaphragm (1) is received at the light receiving part (3), and a displacement of the diaphragm (1) is converted into an output from the light receiving part (3), a concave diaphragm is used and the concave face is directed toward the light emitting part (2) and the light receiving part (3). According to the arrangement, light emitted from the light emitting part (2) and reflected off the diaphragm (1) impinges efficiently on the light receiving part (3) in the form of focused light.
