    • A lens module includes: a lens forming an image of an object; a lens holder to hold an outer peripheral side of the lens to allow reciprocal movement in an optical axis direction of the lens; a housing at least one end side of which is opened, which includes a cylindrical receiving part having an inner surface, one surface of which, at a lateral side, contacts one surface of the lens holder at the lateral side perpendicular to the optical axis direction, and which receives the lens holder in the receiving part to allow reciprocal movement in the optical axis direction of the lens and in a sliding state; and an actuator part including a movable part which is displaced by a displacement amount corresponding to a level of an applied drive voltage and reciprocates the lens holder received in the housing between a first position and a second position in the optical axis direction.

    • A horn speaker system includes a dome-shaped diaphragm, a coil bobbin, a phase equalizer, and a magnetic circuit. The coil bobbin is integral with the dome-shaped diaphragm, and a voice coil is wound on the coil bobbin near a free end thereof. The magnetic circuit coacts with the voice coil for producing forces to actuate the dome-shaped diaphragm. The magnetic circuit includes a cylindrical magnet, a first annular yoke attracted to one end of the cylindrical magnet and having a central opening, a plate cooperating with the first yoke in defining a gap in which the coil bobbin is inserted, and a second yoke attracted to an opposite end of the magnet. The magnet, the first yoke, the first plate, and the second yoke jointly make up a closed magnetic circuit. The phase equalizer serves to keep sounds outputted from the dome-shaped diaphragm in phase. The phase equalizer is mounted on the first yoke and has a plurality of slits defined therein. The magnet, the first yoke, the phase equalizer, and the dome-shaped diaphragm are stacked coaxially with each other.
    • 喇叭扬声器系统包括圆顶形隔膜,线圈架,相位均衡器和磁路。 线圈骨架与圆顶形隔膜成一体,并且音圈绕线机在其自由端附近缠绕在线圈架上。 磁路与音圈共同作用以产生穹顶形隔膜。 磁路包括圆柱形磁体,吸引到圆柱形磁体的一端并具有中心开口的第一环形磁轭,与第一磁轭配合以限定线圈架插入的间隙的板,以及第二磁轭 到磁铁的另一端。 磁体,第一磁轭,第一板和第二磁轭共同组成闭合磁路。 相位均衡器用于保持从圆顶形隔膜同时输出的声音。 相位均衡器安装在第一磁轭上,并且其中限定有多个狭缝。 磁体,第一磁轭,相位均衡器和圆顶形隔膜彼此同轴地堆叠。
