  • Patent number: 5587545
    Abstract: A musical toy in which tappers on the ends of swinging bodies can be swung up and kept upswung without using any springs; space for spring mounting is thereby made unnecessary and the toy can be made small; the manufacturing process can be simplified and resulting mass production benefits and cost reductions can be achieved, and which can operate stably over a long period of time. There are provided a toy body 7, a sound producing body 5 and a control device 54, and the toy body 7 comprises first permanent magnets 23a and 23b and swinging bodies 9a and 9b mounted in the vicinity of the first permanent magnets 23a and 23b.

  • Patent number: 5452901
    Abstract: A remote controllable toy including a plurality of passive toy units, a plurality of transmitters for remotely controlling the passive toy units, and synchronizing signal transmitting means for transmitting a synchronizing signal to the passive toy units and the transmitters. Each of the transmitters of the passive toy units transmits a control signal for controlling the corresponding passive toy unit when identifying a transmission timing allocated thereto by referring to the synchronizing signal. Each of the passive toy units receives both the synchronizing signal and the control signal, and identifies the timing allocated thereto by referring to the received synchronizing signal, so that it is actuated in accordance with the control signal received within the timing allocated thereto.

  • Patent number: 5446236
    Abstract: A musical toy has a simple construction and can accurately produce melodies and rhythms without also producing extraneous mechanical noise. A generally doll-shaped body contains two permanent magnets and is fitted with a pair of swinging members each containing an electromagnetic coil disposed so that it faces the permanent magnets. A control device, containing a rhythm signal generator circuit and a control circuit which creates rhythm drive signals based on the signal from the rhythm signal generator circuit, supplies each of the coils with a separate and independent drive signal. A sound producing body is disposed in the swinging path of each swinging member so that when the swinging member is caused by the magnetic interaction between the coil and the permanent magnets to swing in response to the rhythm signal from the control device, the sound producing body is struck by the swinging member and a musical note is sounded.
