DETAILED DESCRIPTION

Referring to FIG. 1, an activity toy 100 includes a base 110 having an upper surface 112 with hemispherical dimples 114 and balls 116 that can be positioned in the dimples 114. The dimples 114 include dimple switches 118 that cause the toy to produce sounds when they are actuated. A dimple switch 118 can be actuated by placing a ball 116 in the dimple 114 or by pressing the dimple switch 118 with a finger (not shown). Actuating more than one dimple switch 118 at a time can produce a variety of sounds or a combination of sounds. In one implementation, the balls are made from translucent plastic in a variety of colors including red, yellow, green, orange, blue, and teal.

The upper surface 112 of the base 110 includes a sound port 120 and a sound switch 122. The sound port 120 is a series of cut-outs that allows a speaker in the base (not shown) to transmit sound. The sound switch 122 may be shaped as a musical note, such as, for example, a clef. Pressing the sound switch 122 produces a voice and also changes the sound mode between modes that produce music, phrases, and sounds.

The base also includes a mode switch (not shown). Actuating the mode switch changes modes between demonstration mode, play mode with loud volume, and play mode with soft volume. In play mode, the toy 100 is ready for play. In demonstration mode, the activity toy can simulate the sounds and melodies created by playing with the toy 100.

The upper surface 112 of the base 110 includes a ball tray 124. The ball tray is a recess in the base 110 that holds the balls. A slanted area 126 above the ball tray 124 guides balls into the ball tray 124.

Referring to FIG. 2, a sound processor circuit 128 located inside the base 110 produces sounds. The circuit 128 includes a battery 130, a power switch 132, dimple switches 118, a sound switch 122, a sound generator 134, a speaker 136, and a mode switch 138. The power switch 132, which is located on the base 110, provides power to the sound processor circuit 128. The dimple switches 118, sound switch 122, and mode switch 138 provide inputs to the sound generator 134.

Lights 140 are mounted inside the base 110 directly under each dimple switch 118. Each light 140 is electrically connected to a dimple switch 118 so that the light 140 is activated when the switch 118 is actuated. The light 140 illuminates a translucent ball 116 positioned in the dimple to make the ball appear to glow.

The sound generator 134 is a microprocessor that is programmed with a variety of sounds. The sounds can be phrases or music that are repeated in a sequence or in a random order. The sound generator 134 produces a combination of sounds when several of the dimple switches are actuated simultaneously.

The sound generator 134 changes sound modes between music, sounds, and phrases when the sound switch 122 is actuated. The output of the sound generator 134 is connected to the speaker 136. The sound generator 134 also may include an amplifier circuit (not shown) to increase the volume of the sound.

Referring to FIG. 3, the game is prepared for play according to a procedure 142. The player is provided with an activity toy that has the features described above (step 144). The player turns the game on by activating the power switch (step 146). The mode switch prepares the toy for play or for demonstration (step 148). If the player is not familiar with the game or would like to observe the game, the player can select the demonstration mode using the mode switch (step 150). In the demonstration mode, the activity toy may produce sounds and light and may provide the user with playing instructions.

To ready the game for play, the player selects a play mode (step 152). The player also may choose between play modes (step 154) with loud or soft volumes. In one implementation, the mode switch 138 may be a three position switch that allows the user to select between a demonstration mode, a play mode with loud volume, and a play mode with soft volume. In another implementation, the activity toy 100 has a separate volume switch that allows the player to select loud or soft volumes.

Next, the player presses the sound switch 122 to select from the desired sound modes of music, voice and sounds (step 156). In one implementation, the sound circuit 100 is programmed to begin in the music mode. Each time that the sound switch 122 is pressed, the sound circuit may advance to the next sound mode until the desired sound mode is selected. In another implementation, pressing the sound switch 122 without any balls 116 in the dimples 114 produces a few measures of music notes when the toy 100 is in music mode. In addition, a metronome sound may then play for about 15 seconds to indicate that the toy 100 is in music mode. In a further implementation, pressing the sound switch 122 while a song is playing changes the song to the next song in a sequence.

In yet another implementation, the toy 100 may have a sound effects mode. In this implementation, a specific sound effect may play each time a specific dimple switch 118 is actuated. Thus, a young player may learn to associate a specific sound to the action of pressing a specific dimple switch 118. A rhythmic xylophone may sound when the sound switch 122 is pressed to indicate that the toy 100 is in sound effects mode. In this implementation, the toy 100 may revert from sound effects mode to music mode after about a minute of inactivity. A few measures of a tune may then be produced to indicate that the toy 100 is back in music mode.

The balls are then placed in the ball tray (step 158) and the game is ready to start (160). The ball tray 124 may also be used for storage of the balls 116.

Referring to FIG. 4, the game is played according to a procedure 400. The player selects a ball from the ball tray (step 162). The player positions the ball over a dimple (step 164). Next, the player drops the ball with the goal of placing the ball in the dimple (step 166). If the ball misses the dimple, it may roll off the toy or into the ball tray. If the player is successful in dropping the ball into the dimple, the player selects another ball (step 168). As more balls are dropped into dimples, the activity toy produces a combination of sounds. Once the player position balls in all of the dimples (step 170), the game may be played again by placing the balls back into the ball tray (step 158). If no switch is activated within a period of time, the activity toy 100 goes into sleep mode. Once the toy 100 is reactivated, play resumes at the next song in the sequence.

Referring to FIG. 5, a player 172 is shown positioning a ball 116 over the upper surface 112. The player 172 must position the ball 116 directly over a dimple before the ball 116 is dropped. Otherwise, the ball 116 falls off of the toy 100 or back into the ball tray 124 and the player 172 starts again. Depending on the age and the physical coordination of the player 172, the balls 116 may be dropped from greater or lesser heights, tossed, or placed directly into the dimples 114.

The activity toy 100 is appropriate for a very young child. The sounds and light provide stimulation and amusement and assist a toddler in discovering music and other sounds. As the child learns more about music, the child can combine sound tracks by positioning balls 116 in several of the dimples 114. Game play also helps to develop coordination and motor skills. The base 110 of the activity toy 100 may have a relatively low height to allow a toddler that is still learning to walk to play from a seated position.

Referring to FIGS. 6 and 8A, an activity toy can be shaped as a vehicle, such as, for example, a farm tractor 174 or a rowboat 176. As shown in FIG. 6, the tractor 174 includes an upper surface 178 with recessed regions 180. The tractor has other features, such as wheels 182, an engine compartment 184, a front grill 186, a smoke stack 188, and side rails 190.

Referring to FIGS. 7A–7D, figures with a farm theme, such as, for example, a farmer 192, a pig 194, a cow 196, and a duck 198, are configured to be positioned in the recessed regions 180 of the tractor 174.

Referring to FIG. 8A, the rowboat 176 includes recessed regions 200, with each recessed region having a raised post 201 having a center contact 203 and an outer contact 205. Referring also to FIG. 8B, a FIG. 207 may be positioned in the recessed region 200. The bottom of the figure has a hole 209 with a center conductor 211 and an outer conductor 213. With the FIG. 207 positioned in the recessed region 200, the center contact 203 makes contact with the center conductor 211 and the outer contact 205 makes contact with the outer conductor 213.

Referring to FIGS. 9A–9D, figures with a sea-going theme, such as, for example, crew members including a captain 206, sailors 208, 210, and a mate 212, are configured to be positioned in the recessed regions 200 of the rowboat 176. Referring to FIG. 10, each of FIGS. 206, 208, 210, and 212 may be inserted into any of the recessed regions and may, but need not, face the bow 214 of the rowboat 176.

Referring to FIG. 8C, in another implementation, the recessed region 200 has contact posts 202 and a ridge 204. In the alternative implementation described with respect to FIG. 8C, each of FIGS. 206, 208, 210, 212 has a slot (not shown) that matches the ridge 204 such that the figures must face the bow 214 of the rowboat 176 in order to be properly positioned in the recessed regions 200.

Referring to FIG. 9E, each figure includes a resistor 216 that is connected between the center conductor 211 and the outer conductor 213. The resistor 216 in each figure may have a different resistance value. When a figure is positioned as shown in FIG. 10, an electrical circuit through the resistor 216 is completed by contact between the center contact 203 with the center conductor 211 and the outer contact 205 with the outer conductor 213.

The rowboat 176 has other sea-going features, such as, for example an anchor 218, oars 220, and a rudder 222. The rowboat also has wheels 224 for motion on flat surfaces.

Referring to FIG. 11, the tractor 174 and the rowboat 176 each have a sound circuit 226 that can be actuated by positioning the toy's respective figures in the recessed regions 180, 200. The sound circuit 226 includes a power supply 228, an integrated circuit 230, and a speaker 232. In one implementation, the integrated circuit 230 is a Sonix SNC582 dual-channel directive drive speech controller. Other implementations may use other integrated circuits with similar features.

A resistor 234 is connected between the power supply 228 and the integrated circuit 230 to establish an oscillation frequency. A capacitor 236 is also connected to the power supply 236 to reduce voltage fluctuations. A power switch 238 and a mode switch 240 are ganged together to provide power to the circuit 226 and to program the circuit for either demonstration or play mode.

A switch 242 is incorporated into the tractor 174 or the rowboat 176 to allow a user to actuate the sound circuit without insertion of a figure in the recessed regions. For example, the switch 242 may be positioned in the smokestack 188 of the tractor 174 or behind the anchor 218 of the rowboat 176. When the smokestack 188 or the anchor 218 is pressed, the switch 242 actuates the sound circuit 226.

Each pair of contact posts 202 includes one post connected to a terminal of the integrated circuit 230 and one post connected a supply voltage such that a circuit including a resistor 216 is established between the supply voltage and the terminal of the integrated circuit when a figure is positioned in a recessed region. Capacitors 299 are connected between these terminals of the integrated circuit and electrical ground.

Depending on the resistance of the resistor 216, the capacitor 244 charges from ground potential to a threshold voltage in a set period of time. The integrated circuit 226 measures and stores the capacitor charging time period. Thus, figures can be differentiated by the sound circuit 226 based on unique resistance values of the resistors 216 located in each figure. Typical values for the timing components of the sound circuit 226 are between 15K–100K ohms for the resistor 216 and 1 microfarad for the capacitor 244.

In operation, the toy 174 or 176 plays different sounds and music depending on the position of the figures. For example, when the farmer is placed in the forward recessed region of the tractor (driver position), the toy determines if the other farm animals are present. If no other farm animal is in the tractor, the farmer stops to ask: “Hey, where is everyone?” If farm animals are positioned in the tractor, the farmer states, “here we go,” and the song “Old MacDonald” along with accompanying instrumental music begins to play.

Different verses of the song will play depending on which farm animal is present. For example, the song may begin: “Old MacDonald (that's me!) giggle has a tractor, ee i ee i oh!” If the pig is in the tractor, the farmer voice sings, “And on my tractor I have a pig, ee i ee i oh! With an oink-oink here, and an oink—oink there, here oink—oink there oink—oink, everywhere oink—oink.” If the cow is in the tractor, the song continues, “and on my tractor I have a cow, ee i ee i oh! With a moo—moo here, and a moo—moo there, here a moo—moo, there a moo—moo, everywhere a moo—moo.” And if the duck is present, the song continues, “And on my tractor I have a duck, ee i ee i oh! With a quack—quack here, and a quack—quack there, here a quack—quack, there a quack—quack, everywhere quack—quack.”

If any character is removed during the song, the toy utters “uh-oh”, then continues the song. If the pig, cow or duck are placed in the driver position, the animal states: “Uh-oh . . . I can't drive . . . ” and sound effects made by that animal begin playing, such as, for example, oink, moo or quack sounds. If all characters are removed, the toy plays an instrumental version of “Old MacDonald.”

The rowboat sounds are based on a sea-going theme and the song “Row Your Boat.” Various scripts also are played depending on the character positioned in the rowboat. If the captain is in the captain's position closest to the bow, the captain states “Hey?! Where is everyone?” if other characters are not present, or “Here we go . . . ” if other characters are present. If a sailor is placed in the rowboat without the captain, the sailor exclaims, “Uh-oh?! I can't sail by myself! (giggle)” The toy then begins playing: “Row, row, row your boat, gently down the stream, merrily, merrily, merrily . . . life is but a dream.” Various instrumentals also play along with the song depending on the characters positioned in the rowboat.

A number of implementations have been described. Nevertheless, it will be understood that various modifications may be made. For example, a ball tray may be configured to extend around the entire perimeter of the base to keep dropped balls on the base. In another implementation, a switch may be located in the ball tray to produce a sound when a dropped ball actuates the switch. In a further implementation, the toy may be another type of vehicle, such as, for example, a train or an airplane. Accordingly, other implementations are within the scope of the following claims.
