DESCRIPTION OF PREFERRED EMBODIMENT WITH REFERENCE TO DRAWINGS
A first embodiment of a crayon and sound emitting device assembly is generally indicated by reference numeral 20 in FIGS. 1(a) and 1(b). The assembly 20 consists of a crayon 22 and sound emitting device 24. The crayon 22 has a distal marking end 26 remote from the sound emitting device 24 which is adapted to mark paper (not shown) with a particular colour, for example, red. The crayon 22 has an identifying termination 28 at an end opposite from the distal marking end 26 consisting of a plurality of projecting knobs 30. The identifying termination 28 is adapted to be received inside a socket 32 forming part of the sound emitting device 24 where the knobs 30 trigger a corresponding array of built in switches (not shown) inside the sound emitting device.
The sound emitting device 24 has a speaker 34 operatively connected to a microprocessor and an integrated circuit (not shown) which are housed inside the sound emitting device. The array of switches triggered by the identifying termination 28 operates to produce an audible message associated with the colour red which is transmitted through the speaker 34.
The identifying termination 28 of the crayon 22 of FIG. 1 has a round base supporting a circular array of five knobs 30 also shown in FIG. 2(a).
In FIG. 2(b), a crayon 32 having a distal marking end 34 adapted to mark paper (not shown) with the colour blue has an identifying termination 36 with a square base supporting a square array of four knobs 38.
In FIG. 2(c), a crayon 40 having a distal marking end 42 adapted to mark paper (not shown) with the colour yellow has an identifying termination 44 with a triangular base supporting a triangular array consisting of three knobs 46.
It will be understood that a universal sound emitting device 24 is physically coupled to a selected crayon and that the nature of the audible message which is transmitted through the speaker 34 is determined by the array of switches inside the sound emitting device 24 which is triggered by the particular identifying termination (28, 36, 44) of the crayon (22, 32, 40) which is being coupled to the sound emitting device 24.
The universal sound-emitting device 24 may be moved from crayon to crayon or each crayon may be coupled to a respective sound emitting device. Optionally, the sound emitting device is integral with the crayon.
In a second embodiment of the invention shown in FIGS. 3(a) and (b), a crayon 48 having a distal marking end 50 has an identifying termination 52 consisting of an electric resistance element 54 of predefined resistance. The resistance of electric resistance elements will differ from crayon to crayon in a set of crayons. The electric resistance element 54 is embedded in a plastics cap 56 which is fused to the crayon 48 and has a pair of electrical contacts 58 which protrude through the cap 56.
The cap 56 is dimensioned to be received in a socket 60 formed at one end of a sound emitting device 62 which houses a speaker 64, a microprocessor and an integrated circuit (not shown). The electrical contacts 58 close an electrical circuit inside the sound emitting device 62 which will produce a predefined audible sound according to the resistance of the electric resistance element 54 inside a crayon.
In a third embodiment of the invention shown in FIGS. 4(a) and (b), a crayon 66 having a distal marking end 68 has an identifying termination 70 consisting of a microscopic wave generator which may be an electromagnetic coil or ultrasonic and which is unique to each crayon in a set. The microscopic wave generator is embedded in a plastics cap 72 which is fused to the crayon 66 and which communicates with a sound emitting device 74 which houses a speaker 76, a microprocessor and an integrated circuit (not shown).
Conveniently, the sound emitting device 74 has a socket termination 78 for receiving the identifying termination 70. However, the sound emitting device 74 may be activated without being physically coupled to the crayon 66.
In a fourth embodiment of the invention shown in FIGS. 5(a) and (b), a writing implement 80 comprises a writing portion 82 and a sound-producing portion 84. The writing portion 82 is preferably a wax crayon, but can also be a marker, pen or pencil, as other forms of writing implement are also within the scope of the invention.
Writing portion 82 has a marking end 86 and a connector 88 comprising an identifying termination 90 and a slot 96. Sound-producing portion 84 houses a sound-producing unit 100 and comprises another connector 98, for example a socket, adapted to receive connector 88. Writing portion 82 can be retained in socket 98 in a number of ways, including, but not limited to, by friction fit, clasp or snap.
Within connector 88 and socket 98 are corresponding electrical connectors to allow communication between writing portion 82 and sound-producing portion 84. Identifying termination 90 comprises a plurality of connection points 92, for example pins, projecting from the end opposite to marking end 86. In this embodiment, a four-pin connector is conductively attached by, for example, soldering, to circuit board 94, although other numbers of pins are clearly within the scope of the invention. A subset of pins 92, in this case the first and third, are connected on circuit board 94. This combination serves to identify a characteristic of writing portion 82 to sound-producing portion 84.
When combined, as shown in FIG. 1(b), pins 92 engage a mating header (not shown) attached to sound producing unit 100 within sound-producing portion 84. In order to properly align pins 92 and sound-producing unit 100, an inner rib (also not shown) is provided extending longitudinally along an inner surface of socket 98. This rib engages slot 96 so as to angularly align writing portion 82 and sound-producing portion 84 and ensure the proper electrical connection of pins 92 and the mating header.
With the two portions combined, sound-producing portion 84 is operable to identify writing portion 82 by identifying termination 90. With pins 92 in communicative engagement with sound-producing unit 100 via the header housed within portion 84, sound-producing unit 100 is operative to identify the characteristic of writing portion 82, for example the color of marking end 86, by recognising the combination of connected pins 92 on board 94.
With the recognition of writing portion 82, sound-producing unit 100 is enabled to play a sound recording stored inside unit 100. The sound recording can be played automatically upon connection of writing portion 82 and sound-producing portion 84, or in response to a user input, for example the push of a button. Alternatively, the sound recording could be stored on board 94 within writing portion 82 and sound-producing portion 84 is mainly an amplifier and speaker.
The sound recording can comprise music, words, a sound effect or any combination thereof. Preferably, the sound recording is associated with the characteristic of the writing portion detected by unit 100. For example, upon insertion of writing portion 82 into sound-producing portion 84, a sound recording comprising an identification of the color of portion 82 is played. In addition, that color can be spelled and the user instructed to use writing implement 80 in a specific manner.
When a number of writing portions 82 are provided with a sound-producing portion 84 that can recognise each one, a play pattern can be established. Upon assembly with a first writing portion 82, unit 100 plays a recording identifying the color of that portion 82, lists every-day objects associated with that color and instructs the user to draw. Subsequently, the user can be prompted to select another writing portion 82 having a different characteristic and the play pattern continues.
A coloring book can also be provided along with the set of writing portions 82 and sound-producing portion 84. This book can be tailored specifically for use with the sound-producing writing implement 80 and the plurality of colors provided by writing portions 82. The play pattern stored in sound-producing unit 100 can incorporate use of the provided coloring book.
The crayon assembly according to the invention is an educational fun toy which will teach young children how to spell and distinguish their colours. The talking “head” or sound emitting device responds when a crayon is inserted; its “brain” or microprocessor detects what colour it is, says and spells the name and gives an example of common objects normally of that colour. It then prompts the child to draw with that crayon. Preferably, each crayon set comes with one talking “head” and six colourful crayons (blue, green, orange, purple, red and yellow).
It will be understood that several variations may be made to the above-described embodiments of the invention as will be apparent to those skilled in the art.
