    • A multi-tone sounder system including the sounder and a method of controlling the sounder in which at least a pair of chime bars (3, 5), bells or gongs are spaced apart and arranged to be struck by a solenoid operated striker (26) positioned between the chime bars; the solenoid (24) is powered by a controller (FIG. 2) in one of several ways so that in one way by sudden application of power to the solenoid the striker strikes one bar but then the power is reduced gradually preventing the striker by means of a spring (28) hitting the other bar; in a second way by gradual application of power to the solenoid and sudden reduction the other bar only is struck; in a third way by sudden application and a sudden reduction of power to the solenoid both bars may be struck; by using a predetermined combination of strikes a particular push button in a house can easily be identified.

    • The present invention relates to an electromechanical wind chime. The chime includes a disk from which a hammer assembly is suspended. Additionally, a plurality of tubular chimes are suspended from the disk and surround the hammer assembly. The hammer assembly houses an internal electric motor, and an associated eccentric rotor. The motor serves to move the assembly about a central axis. In this manner, the hammer assembly comes into contact with the chimes to produce a pleasing sound. A control unit is coupled to the hammer assembly by way of an electric cord. The control unit includes means to control the current being delivered to the electric motor. Through the control unit the current can be shut off after a predetermined amount of time has elapsed. Additionally, the unit can alternate the frequency with which the current is delivered to produce a more random motion. An embodiment employing a solenoid in place of an electric motor is also disclosed.
    • 本发明涉及机电风铃。 钟声包括一个盘,锤子组件从该盘悬挂起来。 此外,多个管状气泡从盘悬挂并围绕锤组件。 锤组件容纳内部电动机和相关联的偏心转子。 电动机用于围绕中心轴线移动组件。 以这种方式,锤组件与钟声接触以产生令人愉快的声音。 控制单元通过电线连接到锤组件。 控制单元包括用于控制被传送到电动机的电流的装置。 通过控制单元,可以在经过预定的时间后关闭电流。 另外,该单元可以交替传送电流的频率以产生更随机的运动。 还公开了采用螺线管代替电动机的实施例。

    • An electromechanical chaotic chiming mechanism, analogous to the classical wind or water powered chime, includes a body or framework suspending a series of chimes with a pendulum suspended centrally among the chimes. A drive mechanism for the pendulum includes a permanent magnet on the pendulum and a drive electromagnet in a base positioned just below a centered rest position of the pendulum. With the electromagnet switched on and off, in a regular linear pattern, the electromagnetic drive causes a chime hammer on the pendulum to behave in a chaotic manner, sounding the chimes in a fashion virtually indistinguishable from natural meteorological forces acting on conventional windchimes. Variations can be made to the pattern or period of the drive electromagnet to vary the pattern of sound produced by the chimes.
    • 类似于经典风或水动力钟的机电混沌搅拌机构包括悬挂一系列钟形的身体或框架,其中钟摆悬挂在钟声之间的中心。 用于摆锤的驱动机构包括摆锤上的永磁体和位于摆锤中心静止位置正下方的基座中的驱动电磁体。 随着电磁铁开启和关闭,电磁驱动器使摆锤上的钟声锤子以混沌的方式发挥作用,使得气球以与常规风力发电机上的自然气象力几乎无法区分的方式发声。 可以对驱动电磁体的图案或周期进行变化,以改变由钟声产生的声音的图案。
