    • The stator of the sound generator in the siren of this invention is mounted on struts that diverge upwardly from the top of an upright post, with its axis coinciding with that of the post. The coaxial rotor of the sound generator is driven by a motor mounted on top of the stator. Sound from the generator is concentrated and directed by a horn that flares along its length from a closed end portion to a mouth. The closed end portion is dome-like and concentrically surrounds and covers the sound generator, opening unrestrictedly downwardly into a bottom portion of the horn that curves along its length so that the mouth, which is wholly spaced below the sound generator, opens to one side of the post. The post extends through a bottom wall portion of the horn. Rollers supported by the stator engage a downwardly facing annular track surface in the closed end portion of the horn to support the horn for rotation, one roller being rotatably driven from the siren motor to rotate the horn during siren operation.
    • 本发明的警报器中的发声器的定子安装在从立柱的顶部向上分开的支柱上,其轴线与柱的轴线重合。 发声器的同轴转子由安装在定子顶部的电机驱动。 来自发生器的声音集中并由一个喇叭指向,该喇叭沿着其长度从封闭的端部向嘴张开。 封闭的端部是圆顶状的并且同心地围绕和覆盖声发生器,不限制地向下打开喇叭的底部,使其沿其长度弯曲,使得完全间隔在声发生器下方的口向一侧开口 的帖子。 柱延伸穿过喇叭的底壁部分。 由定子支撑的滚子在喇叭的封闭端部接合面向下的环形轨道表面,以支撑喇叭旋转,一个滚轮从警笛马达可旋转地驱动以在警笛操作期间旋转喇叭。

    • A siren for an alarm adapted to be driven by a fractional horsepower motor and provided with a cup shaped rotor cooperating with a stator provided with perforations in the cylindrical flange thereof, and a drawn, cup-shaped screen or grille seated over the inlet to said stator and having a cylindrical flange extending over the perforations of the stator but spaced outwardly therefrom, the base of the screen being engaged on the stator rim. The intake air flow of the siren is restricted by the perforations of the screen which increases the velocity of the intake air, thereby increasing the efficiency of the siren which enables reduction of the current usage requirements. The harmonics of the output sound are increased by the perforated cylindrical flange of the screen thereby increasing the volume and pitch of the emitted sound.
    • 一种用于报警器的警报器,其适用于由马达的马力马达驱动并且设有与在其圆柱形凸缘中设有穿孔的定子配合的杯形转子,以及在所述入口上设置的拉制的杯状筛网或格栅 定子并且具有延伸在定子的穿孔上但与其间隔开的圆柱形凸缘,屏幕的底部接合在定子轮辋上。 警报器的进气流量受到屏幕穿孔的限制,从而提高了进气的速度,从而提高了能够降低当前使用要求的警笛效率。 输出声音的谐波通过屏幕的穿孔圆柱形凸缘增加,从而增加了发出的声音的音量和音高。
