Please with reference to Fig. 1, the utility model is a kind of key reminiscences, has housing 1, key ring 2; Frizzen 3, the top of housing 1 are equipped with battery case 4, sound circuit plate 5, loudspeaker 6, and the middle part of housing 1 is equipped with spring base 7; Back-moving spring 8 is installed in the spring base 7, and the front end of the rear end of frizzen 3 and back-moving spring 8 is affixed, and the front end of frizzen 3 stretches out in housing 1; The front portion of frizzen 3 is provided with the galianconism 9 that stretches out obliquely, and the end of galianconism 9 is connected with metal contact 10, and conducting strip 11 is installed on the front side wall of housing 1; The aligned in position of the position of conducting strip 11 and metal contact 10, key ring 2 is made up of the tinsel bending, and its front portion is divided into straight bar part 12; The rear portion is divided into crotch part 13; Key ring 2 is hinged on through rotating shaft 14 on the rear wall of housing 1, and the crotch part 13 of key ring 2 is exposed to housing 1, and the end of the straight bar part 12 of key ring 2 is connected with conductive contact 15.

The connecting structure for electrical equipment of above-mentioned each parts is: battery case 4 is connected with sound circuit plate 5 through a lead 16; Sound circuit plate 5 is connected with loudspeaker 6 through No. two leads 17; Loudspeaker 6 is connected with the straight bar part 12 of key ring through No. three leads 18; No. three lead 18 is crooked, and flexible leeway is arranged, to adapt to the deflection of key ring 2.The conductive contact 15 of straight bar part 12 ends and the back end in contact of back-moving spring 8; Back-moving spring 8 is made up of metal spring; Can conduct electricity, the front end of back-moving spring 8 is connected with the metal contact 10 of galianconism 9 ends through No. four leads 19, and conducting strip 11 is connected with battery case 4 through No. five leads 20.Door key 21 hangs on the crotch part 13 of key ring 2, and when owner did not go out, door leaf 22 was in closed condition; The front end of frizzen 3 is replaced on door leaf 22; Receive the thrust of door leaf 22, frizzen 3 has overcome the elastic force of back-moving spring 8, backward withdrawal; The metal contact 10 of galianconism 9 ends does not contact with conducting strip 11, not conducting of electric loop.

Please with reference to Fig. 2, when owner leaves home to go out, if forget the door key 21 that takes off on the key ring 2; Then when opening the door, door leaf 22 is opened, frizzen 3 playback; Frizzen 3 stretches out forward under the elastic force effect of back-moving spring 8, and the metal contact 10 of galianconism 9 ends contacts with conducting strip 11, the electric loop conducting; Sound circuit plate 5 sends language or melody, is play by loudspeaker 6, reminds owner to carry key.

Please, when owner leaves home to go out,, carry if take off the door key 21 on the key ring earlier with reference to Fig. 3; Then when opening the door, door leaf 22 is opened, frizzen 3 playback, and frizzen 3 stretches out forward under the elastic force effect of back-moving spring 8; The metal contact 10 of galianconism 9 ends contacts with conducting strip 11, but this moment, because the door key 21 on the key ring 2 has been removed; Under the action of gravity of conductive contact 15, key ring 2 is that the center of circle deflects with rotating shaft 14, disengages between conductive contact 15 and the back-moving spring 8; Not conducting of electric loop, sound circuit plate 5 does not send voice or melody, shows that owner has carried key and gone out.
