Audio label

Abstract

The invention relates to radio-engineering. The invention increases the operational reliability and user convenience of the inventive label. In the first embodiment, the inventive audio label comprises a message reproducing block provided with a loud speaker and a switch. Said label is also provided with the second switch operative to lock upon an external activation. One end of the cord for attaching to an object is connected to the first switch, thereby allowing the first switch to lock, when the cord is drawn. In the second embodiment, the audio label comprises second and third switches and a control block.

We claim:  
     
         1 . A sound-reproducing label comprising a housing equipped with a cord for attaching to an object and displaced in said housing a message reproducing block with a loudspeaker, a first switch, a power supply, connected to said message reproducing block through said first switch, and a second switch, coupled to control input of said message reproducing block to start its work, wherein said first switch is made with a forced return into an unlocked position when there is no external activation of said switch and at least one of the ends of said cord is connected to said first switch so that the stretching of said cord locks said first switch and wherein said second switch is operative to be locked by an external activation.  
     
     
         2 . The sound-reproducing label of  claim 1 , further equipped by a capacitor attached between the supply inputs of said message reproducing block.  
     
     
         3 . The sound-reproducing label of  claim 1 , wherein said cord for attaching to an object is made out of an elastic material and has a length providing the fastening of said sound-reproducing label to an object with said cord being stretched.  
     
     
         4 . The sound-reproducing label of  claim 1 , wherein the first end of said cord is fastened to said housing, and its second end is fastened to said first switch and has a limiter of said cord extraction out of said housing.  
     
     
         5 . The sound-reproducing label of  claim 1 , wherein both ends of said cord are located on one of the housing sides so that said sound-reproducing label can be hung on said object.  
     
     
         6 . A sound-reproducing label comprising a housing equipped with a cord for attaching to an object and displaced in said housing a message reproducing block with a loudspeaker, a first, second and third switches, a control block, a power supply, connected to said message reproducing block and said control block through said first switch and said second switch which are serially connected, 
 wherein said first switch is made with a forced return into an unlocked position when there is no external activation of said first switch and at least one of the ends of said cord is connected to said first switch so that the stretching of said cord locks said first switch, said second switch is operative to be locked by an external activation, said third switch is attached in parallel to said second switch and its control input being connected to the output of said control block.    
     
     
         7 . The sound-reproducing label of  claim 6 , wherein said control block comprises serially connected a delay element, a threshold element, and a monostable multivibrator, an output of which is an output of said control block.  
     
     
         8 . The sound-reproducing label of  claim 6 , further equipped with a capacitor attached between the point of connection of said first and second switches an said power supply output not connected to said first switch.
