Abstract: A greeting card having a first card panel, a door connected to the first card panel and movable between a closed position where the door substantially covers a section of the first card panel and an open position where the door uncovers the section of the first card panel. A trigger is provided which is movable between a first position wherein the door is prevented from moving, and a second position wherein the door is allowed to move between the closed and open positions. A member which is movable by a user controls operation of the trigger to move the trigger to the second position to allow the door to move to the open position.

Abstract: An electronic engine for generating acoustic musical notes for simulating a music box. The engine includes a memory for storing data, and an electronic controller connected to the memory for producing a control signal in accordance with said data. A plurality of tone generating members, such as tines from a comb are provided, with each tine generating a corresponding musical note when the tine is placed in motion. One or more actuators in communication with the controller generate a temporary magnetic field in response to the control signal for resonantly adding energy to the tines without requiring physical contact between the tines and the actuators to produce the corresponding musical notes.
