ABSTRACT:
A new and improved automatically actuated music apparatus includes an infrared wave transmitter unit mounted on a door and also includes a music generating unit placed in a room which automatically receives infrared waves transmitted from the door-mounted wave transmitter unit when the door is opened. The door-mounted wave transmitter unit transmits waves in a predetermined wave pattern as the door is opened, and the wave receiver assembly of the music generating unit is positioned in the room so that the wave receiver assembly automatically receives activating wave energy from the door-mounted wave transmitter unit when the door is opened. The door-mounted wave transmitter unit is switched on when a door lock assembly is unlocked in an authorized manner, such as by a key. The door lock assembly is mounted on the door, and a transmitter actuator assembly, attached to a portion of the door lock assembly, actuates the door-mounted wave transmitter unit. The door lock assembly may be mounted in a first housing portion. The door-mounted wave transmitter unit is mounted in a second housing portion. The transmitter actuator assembly projects from the first housing portion through a slot into the second housing portion for actuating the door-mounted wave transmitter unit. The transmitter actuator assembly is operated by a spring bolt in the door lock assembly.
