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. The swinging bodies 9a and 9b comprise tappers 11a and 11b for striking the sound producing body 5 and acting parts for magnetically interacting with the first permanent magnets 23a and 23b and generating a swinging force; the acting part comprises second permanent magnets 31a and 31b for swinging the tappers up and coils 29a and 29b for swinging down the upswung tappers against the resistance of the second permanent magnets 31a and 31b.
