Abstract: Disclosed is a block toy for music education which recognizes combined melody blocks so as to replay sounds in order having the same pitch as the melody blocks, thereby playing a melody. The corresponding melody block is lit up to display a playing melody block while playing a melody. It is possible to differentiate each melody block by detecting, with a mechanical switch, uneven patterns formed at the lower sides of melody blocks. Since music can be visually understood, the block toy can help the emotion and music education of children.

Abstract: Pieces of a conventional jigsaw picture puzzle are cut to fit within a frame and over a base. Each piece has a suitable actuator (e.g., a magnet) embedded therein. The base has a switch (e.g., a magnetic switch) located below the location of the magnet of a particular piece when that piece is properly positioned within the frame to "solve" the puzzle. The switches are wired in series with a source of power, a melody generator and an amplifier. When the puzzle pieces are in proper position, the melody generator produces a tune appropriate for the picture of the puzzle. Several different puzzles may be provided fitting within the same frame. For each puzzle there is a key piece. For different puzzles the switch actuator of the key piece of located in a different location. A separate switch is located on the base below each actuator of the key piece and is wired to generate a different tune by being in series with a different melody generator. Instead of generating tunes, the device may actuate lights or speech.

Abstract: The present invention relates to a game including a set of pieces having different outlines or otherwise differently configured whereby each is engageable into an individual location on a playing surface e.g. by insertion therein. A set of display elements each associated with one of the locations may be activated to indicate visibly when a piece is to be engaged with its associated location. A switch associated with each location is so arranged as to be operable when, and only when, the piece of the correct configuration is engaged in the location. An electrical operating circuit activates the display elements successively in an initial period and then activates only one display element. When the correct piece is engaged with the location corresponding to the activated display element the control circuit responds by deactivating the display element or by adjusting the sound from a sound source.
