| description | A musical electronic lock 10 is provided to unlock a locking means 12. The musical electronic lock 10 comprises a digital tone generation circuit 20 and memory 18 for electronically producing a musical melody while an electronic logic circuit 16 decodes responses from a user. Responses are compared by the electronic logic circuit 16 with an electronically stored combination and timing information in the memory 18. When successfully operated, the user will activate a switch or switches 24 in a key input unit 14 to input a confidential alphameric code when prompted by particular notes of an electronically synthesized musical melody or other sequenc of audible tones generated by a speaker 22. The necessary information to operate the musical electronic lock 10 is significantly more difficult to disseminate than conventional combinations yet it is is far simpler to operate, due to the easy to remember musical melody. |
