Abstract
A sounding mechanism for a toy animal for producing a continuous animal sound of varying tonal quality such as the whinny of a horse. The sounding mechanism comprises a sound housing having an air inlet chamber, an air outlet resonator chamber and an air passage interconnecting the two chambers. A pair of primary and secondary vibratory reeds are coupled together and mounted in the inlet chamber. The primary reed cooperates with one end of the air passage. Apparatus is provided connected to the air outlet chamber for sucking air through the air inlet chamber, air passage and air outlet chamber in succession for initiating vibration of the primary reed. Vibration of the secondary reed by any known mechanism while the primary reed is vibrating alternately varies the effective length of the primary reed for producing a continuous animal sound of varying tonal quality.
