Musical electronic lock

DETAILED DESCRIPTION What is claimed is: 1.
An electronic locking system responsive in operation to manually generated input response signals prompted by audible musical tones comprising: means for initiating the production of a predetermined sequence of audible tones; means for manually generating input signals during the production of said predetermined sequence of audible tones; means for monitoring the time and duration of each of said audible musical tones and of each of said input signals; and means responsive to said monitoring means for operating said locking system upon the generation of at least one input signal during the production of one or more of said audible tones.
2.
an eletronic locking system as defined in claim 1 wherein said means for initiating the production of a predetermined sequence of audible tones includes a memory for storing any one of a plurality of predetermined sequences of audible tones.
3.
An electronic locking system as defined in claim 2 wherein said means for manually generating input signals comprises a plurality of switches each of which upon keying thereof is connected to generate a predetermined specific input signal.
4.
An electronic locking system as defined in claim 3 wherein said means for initiating the production of a predetermined sequence of audible tones includes a digital tone generation circuit for producing tone signals corresponding to said audible musical tones.
5.
An electronic locking system as defined in claim 4 wherein said monitoring means includes a programmable microcontroller responsive to said input signals to execute an interrupt procedure to determine which of said plurality of switches is actuated at any given time.
6.
An electronic locking system as defined in claim 5 including a speaker for converting said tone signals from said digital tone generation circuit into audible musical tones, said microcontroller being arranged to monitor and identify said tone signals as they are generated and to monitor and identify said specific input signals generated by keying of one or more of said switches and to produce an actuation signal for operating said locking system
