Sound circuit plate 4 rounded plate bodys, bearing is in bearing hole seat 33, board body part has three inserting hole ditches 41, cooperate the end pin 52 of shell fragment 5 to peg graft, the one side is provided with two contacts 42,43, and central authorities hold and are provided with an electronic speech device 44, be coated with metallic(return) circuit 45 in circumference, be provided with the contact portion 46 of relative shell fragment 5 in the central authorities of opposite side;

Shell fragment 5 triangular shape that slightly assumes diamond in shape, central portion is depression and tool protrusion contact 51 slightly, and its three limits end pin 52 plugs together the hole ditch 41 that is fixed in sound circuit plate 4, after wherein this shell fragment 5 is fixed, central portion protrudes contact 51 and is suitable spacing with the sound circuit plate, must contact with contact portion 46 after waiting to push.Another embodiment of above-mentioned shell fragment 5 structures changes shell fragment 5 into coniform spiral spring 5A, be fixedly arranged in the perforate pad 5A1, pad 5A1 and sound circuit plate 4A establish an insulation spacer 5A2 who has a circular hole at interval, and the seat hole 41A of sound circuit plate 4A is located in the leg 51A weldering of helical spring 5A;

The bottom of the anode contact flat spring 5 of two circular batteries 6 is combined in the bearing hole seat 33 of noumenal seat 3;

Insulation paper gasket 7 be rounded ducted body, and cover is organized in 3 of two circular batteries 6 and noumenal seats, insulate in order to generation;

One end of screw compression leg 8 is bigger flat termination 81, and the head bottom part cylinder is provided with and screws togather thread 82, screws togather the screw 921 that protrudes in body flap 9, and the outstanding trunk portion of the other end also has through hole 83;

The opening ora terminalis of body flap 9 is provided with thread 91, screw togather lid and organize in the internal screw thread 331 of the bearing hole of noumenal seat 3 seat 33 ends, body has groove 93, is sheathed with an on-slip elastic tape 931, central rounded protrusion seat 92 at the bottom of the flap, its one has the screw 921 that cooperates screw compression leg 8;

Annulus 10 covers are organized the through hole 83 in screw compression leg 8, and ring portion can be colluded in addition and be hung necklace 11;
