Definitions
- This invention relates generally to dolls and toy figures and particularly to those utilizing sound producing apparatus.
- Dolls have been popular with young children throughout recorded history. Perhaps, the first dolls fabricated were crudely shaped by humans for personal use at a time when human civilization was relatively unsophisticated.

Notsurprisingly, practitioners in the art have responded to this long term popularity by providing a virtually endless variety of dolls. While such variety defies classification of different doll types, all may be generally described as either soft body or so-called "plush" dolls versus hard plastic dolls such as the ever popular fashion dolls. Dolls also may be generally classified as to size ranging from smaller dolls which tend to be hard plastic to large dolls often depicting human infants or other characters in a fanciful appearance. Dolls have also been provided which are animal like rather than human like and have been provided to mimic different ages ranging from infant to adult appearances.

In further accordance with the present invention, the sound output ofdoll 10 is converted to a babbling sound when the user places finger 23 overlyingmouth 21 and moves rapidly up and down in the region ofmouth 21 as indicated byarrows 24 and 25. In the preferred fabrication of the present invention, the sound produced bydoll 10 under such circumstances corresponds to the sound often made by young children as a single tone is audiblized and the child manipulates a finger back and forth across the lips and mouth opening. For lack of a better term, this sound is referred to herein as "babbling". - Figure 2 sets forth a partial section side view of the operative mechanism within

Arecess 46 receives aspring 47 which provides a force againstbrace 45 to maintain the position shown and captivatephototransistor 44.Phototransistor 44 is constructed in accordance with conventional fabrication techniques. - A
sound circuit 40 includes a printedcircuit board 41 supporting a plurality of conventional electronic components such as components such as components 43.Housing 30 forms a pair ofgrooves circuit board 41 to secure it in place. A pair of wires 60 are coupled betweencircuit 40 and phototransistor wires 52 and 53 to operatively coupledphototransistor 44 tocircuit 40. An additional pair of conductive wires 62couples circuit 40 tospeaker 64 and a pair of wires 61 couples arm switch 15 (seen in Figure 1) tocircuit 40. Finally, a pair ofwires 63 couples switch 67 tocircuit 40. -
Circuit 40 further includes an automatic gain control system 32 which is constructed in accordance with conventional fabrication techniques and which controls the trigger level ofphototransistor 44. - In operation, the user activates
doll 10 by turning on/offswitch 66 to the on position shown in Figure 2 which in turn couples the electrical energy of battery 65 tocircuit 40. Thereafter,circuit 40 may be energized by the user squeezing eitherswitch 67 intorso 12 orswitch 55 in arm 15 (seen in Figure 1). In either event,circuit 40 responds to the activation ofswitch 55 or switch 67 to audiblize a selected one of a plurality of sound messages stored withincircuit 40.Circuit 40 is a circuit of the type often referred to as speech circuit or sound circuit and is fabricated in accordance with conventional fabrication techniques and utilizes an internal memory having stored audio data thereon and a microprocessor having a stored instruction set and the stored memory data are utilized by the microprocessor to provide sound signal output. It will be well understood by those skilled in the art that virtually any standard speech circuit may be utilized in place ofcircuit 40 without departing from the spirit and scope of the present invention. The essential characteristic ofcircuit 40 is the provision of appropriate signals tospeaker 64 for audiblizing a predetermined speech message or sound combination each time a particular switch is pressed. For example, a combination of a microprocessor, read only memory, speech synthesizer and audio output amplifier suitable for the functioning ofcircuit 40 is formed as a single integrated circuit chip device manufactured by Texas Instruments, Inc. under the device name TMS50C44. However, it will be understood that a variety of standard integrated circuit devices may be utilized forcircuit 40. - Thus, with

circuit 40 has been triggered byswitch 55 orswitch 67, the user may modulate or superimpose a babbling sound fordoll 10 by placing the user's fingertip back and forth acrossmouth 21 as illustrated in Figure 1. The effect of this movement back and forth causes a relatively fast variation of the light applied tophototransistor 44 throughlight transmissive portion 22 which in turn modulates the audio signal output ofcircuit 40. In the preferred fabrication of the present invention, this modulation is a distortion of the speech or other audio output being produced bycircuit 40 such that the character of the sound is a combination of the original message and the modulation. - Figure 3 sets forth a block diagram of

Alight sensor 44, which in the preferred embodiment of the present invention includesphototransistor 44, is operatively coupled tomicroprocessor 70. Anautomatic gain control 42 is operative upon the output oflight sensor 44 to provide the above-described ambient light adjustment for the light sensor. Ahand switch 55 and atorso switch 67 are coupled to selection inputs ofmicroprocessor 70. An audio amplifier 72 couples the audio output ofmicroprocessor 70 to aspeaker 64. - Thus,
microprocessor 70 operates in accordance with conventional fabrication techniques in response to inputs fromswitch 55 or switch 67 to select a speech output or song output or other previously stored sound for playing through audio amplifier 72 andspeaker 64. In accordance with the present invention, the output oflight sensor 44 is operative uponmicroprocessor 70 to causemicroprocessor 70 to modulate or composite the selected audio signal with a babbling distortion. As a result and in accordance with an important aspect of the present invention, the initiation of the babbling sound by finger motion across the mouth of the doll as shown in Figure 1 results in a distorted babbling sound which is still recognizable as the originally selected sound message. This is accomplished by simple modulation withinmicroprocessor 70. - While particular embodiments of the invention have been shown and described, it will be obvious to those skilled in the art that changes and modifications may be made without departing from the invention in its broader aspects. Therefore, the aim in the appended claims is to cover all such changes and modifications as fall within the scope of the invention, as defined in the appended claims.
