Abstract
A sound generating toy capable of generating sound without any power supply and while being simplified in structure, as well as exhibiting more reality. The toy includes a toy body including a head, in which a mouth (4), a door member (5) pivotally moved when the mouth is charged with a toy food (3), a spiral spring wind-up mechanism (6) actuated in association with the door member, a spiral spring unit (7) and a sound output unit (A) are arranged. When an eccentric rotating member (15) mounted on an output shaft (14) of the spiral spring unit is rotated to engage with a sound generating means (8), the sound generating means cyclically generates sound.

A sound generating toy including a toy body provided with a head (1) and a mouth (4) arranged in said head, wherein
- sound is generated when a toy food is put in said mouth, the sound generating toy comprises:
- a door member (5) arranged in said head so as to be moved when a toy food (3) made in imitation of food is put in said mouth;
- a spiral spring unit (7) including a spiral spring, an input shaft and an output shaft (14) and arranged in said head;
- a wind-up mechanism (6) arranged in said head and actuated in association with said door member to wind up said spiral spring of said spiral spring unit;
- and
- a sound generating means (8) arranged in said head for generating sound, wherein
- said output shaft of said spiral spring unit is mounted thereon with an eccentric rotation member (15), so that rotation of said output shaft causes said eccentric rotation member to engage with said sound generating means to permit said sound generating means to mechanically and cyclically generate a sound.
A sound generating unit that can be incorporated in a toy to generate the simulated sound of eating food comprising:
- a housing member;
- a movable member connected to the housing member that can be positioned in a toy to be activated when the toy receives simulated food;
- a mechanical spring storage mechanism connected to the movable member for storing energy when the movable member is activated and for releasing the energy over a predetermined time period;
- a rotatable member operatively connected to the spring storage mechanism and rotatable when energy is released, the rotatable member including a serrated surface;
- a coil spring;
- a speaker, operatively connected to the coil spring for receiving mechanical vibrations from the coil spring to produce sound, the coil spring mounted in the housing member to contact the serrated surface of the rotatable member.
