Abstract
A movable model of an animal is described in which a driving mechanism adapted to operate synchronously with generation of a sound by a control circuit is incorporated in a simulated animal-like body portion formed of a soft foamed urethane block which has been shaped to the external configuration of a human or animal, and an operating end of said driving mechanism is joined to a part of said soft foamed urethane block forming the body portion of the model so as to induce movement of the moving parts of said body portion.
Claims6
A movable sound-producing model comprising:
- (a) a body portion formed from a soft foamed urethane resin block contoured into the external shape of the desired model, and having formed therein a cavity for housing a link mechanism, driving means, and driving-power transmission means contained therein;
- (b) driving means for generating continuous and modulated driving-power to induce movement of said model;
- (c) a link mechanism having a working-end connected to a part of the soft foamed urethane resin block and another end connected to said driving means for inducing movement of the model;
- (d) sound generating means for generating an audio signal;
- (e) accoustic converting means connected to said sound generating means for producing a sound upon receiving an audio signal from said sound generating means;
- (f) level detecting means connected to said sound generating means for detecting an audio signal from said sound generating means when the generated signal is higher than a predetermined level;
- (g) driving power transmission means within said cavity for transmitting driving-power from said driving unit to said link mechanism in response to a driving control signal;
- and
- (h) control means connected to said driving-power transmission means and said level detecting means for controlling the operation of said power transmission means so as to synchronize the generation of the sound emitted by said sound generating means with the movement of the model in accordance with a detected output signal from said level detecting means to produce a driving control signal at a predetermined period of time to said power transmission means.
