Toy

Abstract

A toy comprising a transducer to produce an output signal in response to variations in barometric pressure, a filter to filter said output signal to select a component of the output signal relating to air movement at the transducer and response means to cause said toy to create an effect in response to receipt of the filtered output signal.

1 . A toy comprising:
 a transducer to produce an output signal in response to a person blowing at the transducer, a filter to filter the output signal, and response means to cause said toy to create an effect in response to receipt of the filtered output signal.   
   
   
       2 . A toy comprising:
 a transducer to produce an output signal in response to a change of barometric pressure, a filter to filter the output signal, and response means to cause said toy to create an effect in response to receipt of the filtered output signal.   
   
   
       3 . A toy comprising:
 a transducer to produce an output signal in response to variations in barometric pressure, a filter to filter said output signal to select a component of the output signal relating to air movement at the transducer and response means to cause said toy to create an effect in response to receipt of the filtered output signal.   
   
   
       4 . A plush toy comprising:
 a transducer to produce an output signal in response to variations in barometric pressure, a filter to filter said output signal to select a component of the output signal relating to air movement at the transducer and response means to cause said toy to create an effect in response to receipt of the filtered output signal.   
   
   
       5 . A plush toy, as claimed in  claim 4 , comprising:
 a teddy bear.   
   
   
       6 . A plush toy, as claimed in  claim 4 , wherein:
 the plush toy further comprises limbs, the toy comprising means to move one or more said limbs in response to receipt of the filtered output signal.   
   
   
       7 . A plush toy, as claimed in  claim 5 , wherein:
 the plush toy further comprises eyes, the toy comprising means to move one or more said eyes in response to receipt of the filtered output signal   
   
   
       8 . A plush toy, as claimed in  claim 5 , wherein:
 the plush toy further comprises at least one sound producing apparatus, the sound producing apparatus being adapted to produce a sound effect in response to receipt of the filtered output signal   
   
   
       9 . A toy, as claimed in  claim 3 , wherein:
 the transducer is selected from a group consisting of a piezo electric device, a microphone, an electret microphone.   
   
   
       10 . A toy, as claimed in  claim 3 , wherein:
 the filter further comprises:   a filter to remove output signals relating to sound.   
   
   
       11 . A toy, as claimed in  claim 10 , wherein:
 the filter means further comprises:   a filter to remove all oscillating signals from the transducer greater than a particular frequency.   
   
   
       12 . A toy, as claimed in  claim 11 , wherein:
 the particular frequency is selected from up to 10 Hz and up to 50 Hz.   
   
   
       13 . A toy, as claimed in  claim 3 , wherein:
 the toy further comprises:   at least one motor driven part, the movement of the motor driven part being controlled by receipt of the filtered output signal.   
   
   
       14 . A toy, as claimed in  claim 13 , wherein:
 the motor driven part comprises a windmill.   
   
   
       15 . A toy, as claimed in  claim 13 , wherein:
 the motor driven part further comprises:   means for producing soap bubbles.   
   
   
       16 . A toy, as claimed in  claim 3 , further comprising:
 a light device; and   means to vary the light produced by the light device in response to receipt of the filtered output signal.   
   
   
       17 . A toy, as claimed in  claim 3 , comprising:
 a snow globe, including a motor means to agitate the snow, the motor means being controlled by means of the filtered output signal.   
   
   
       18 . A toy, as claimed in  claim 3 , wherein:
 the transducer is visible to an external toy user and forms a target, and there is also provided a manually operable air flow producing means enabling manual positioning to direct the air movement at the transducer.   
   
   
       19 . A toy, as claimed in  claim 18 , wherein:
 the effect created is at least one of a sound effect, a lighting effect, and a movement.
