Squeezable musical toy with looping and decaying score and variable capacitance stress sensor
First Claim
1. A musical toy, comprising:
- an elongated stuffed animal having a body, the body comprising a plurality of segments;
a plurality of stress sensors, wherein each of the stress sensors is within a corresponding segment,a microcontroller in communication with each of the stress sensors; and
a speaker;
wherein each of the sensors comprises any of a hemispherical, ellipsoidal, prismatic, or cylindrical shape;
wherein each of the segments comprises padding enclosing one of the sensors, wherein the padding is an outer portion of the body segments;
wherein the microcontroller is programmed to perform the steps of;
adding a musical note to a music loop comprising a repeating sequence of musical notes, wherein the musical note is based upon which of the plurality of sensors is activated, andoutputting the loop through the speaker; and
wherein the microcontroller is further programmed to perform the step of applying a decay function to the music loop.

Abstract
An enhanced toy produces repeating, decaying notes in response to applied pressure. The tone of each note is determined, based on the location at which a user applies pressure. The initial amplitude of each note is proportional to the intensity, as measured by a stress sensor. The toy periodically repeats each note, attenuating the amplitude of each successive repetition by a decay factor. The toy may alter the notes associated with each of a plurality of locations. For example, if all currently repeating notes have decayed below a predetermined threshold, the currently available set of notes may be exchanged for a new set of notes, e.g. with different tones or timbres. The stress sensors may comprise flexible capacitors within the toy. As the user applies pressure, the geometry of one or more capacitors deform, altering the measured capacitance, through which the intensity of the applied pressure is determined.
