Present embodiment has a housing 1 and ear-hang 2 as shown in Figure 1.Angular displacement touch switch 23 is equipped with in the bottom in the housing 1, and battery 3, contactor 4, printed circuit board (PCB) 16, speech chip able to programme 15, triode, resistance, electric capacity and acoustical generator 19 are equipped with in top.

As Fig. 5, shown in Figure 6, these speech chip 15 its English names able to programme are that POWERSPEECH is the W528XXX type that Hong Kong Hua Bang company produces, the main circuit of this reminiscences is the OSC end of this speech chip 15 able to programme connects battery 3 by contactor 4 by resistance R OSC a positive pole, the vdd terminal of speech chip 15 able to programme also connects the positive pole of battery 3 by contactor 4, the negative pole of its VSS termination battery 3, its input end can be any one (present embodiment is selected TG3 for use) joint angle displacement trigger switch 23 of TG port, the output terminal SPK of this speech chip 15 able to programme connects the base stage of switch triode 8050D, the collector of this switch triode 8050D is through the positive pole of acoustical generator 19 by contactor 4 connection batteries 3, and the emitter of this triode 8050D connects the negative pole of battery 3.

As Fig. 2, this angular displacement touch switch 23 shown in Figure 3 an angular displacement fixed support 10 and pendulum mass 8 are arranged.Replace the contact rod in 00215131.6 application, Spring Card electrode 9 is set on angular displacement fixed support 10, the latter has the big easier welding of bonding area.Pendulum mass 8 can rotate around balance staff 5, and it often will be in vertical state owing to gravitate.This balance staff 5 inserts on the angular displacement fixed support 10, and the angle of rotation can be controlled by the handle 6 that is fixed on the angular displacement fixed support 10.When assembling, one end of balance staff 5 is inserted angular displacement fixed support and pendulum mass 8, and an end of balance staff 5 is inserted on the axle bed 20 of housing 1, again the other end of balance staff 5 is inserted on housing 1 second half axle bed 20.Handle 6 stretches out outside the shell by the side mouth 7 of housing 1, and a plurality of grooves 11 are arranged on the inwall of this side mouth 7, and these grooves 11 are all on balance staff 5 on the arc in the center of circle.

As Fig. 1, the both sides at housing 1 lateral port 7 shown in Figure 4 scale 22 is arranged.Outside dust and foreign matter easily enter this reminiscences inside from side mouth 7, and it is ineffective or unstable that balance staff 5, pendulum mass 8 are worked, and for this reason at the position by proximal hole 7, are provided with retaining foreign matter arc 12 on angular displacement fixed support 10.One projection 17 is arranged on the relevant position of handle 6, and this projection 17 matches with the size and the shape of above-mentioned groove 11, and this projection 17 can buckle into this groove 11.Like this, handle 6 can drive angular displacement fixed support 10 and rotate, and the angle of rotation is determined by handle 6 and scale 22.Therefore pull handle 6 and can adjust relative position between charged pendulum mass 8 and the Spring Card electrode 9, to adjust the shake-up angle of warning.Scale 22 can make angular displacement fixed support 10 location more accurate.Because pendulum mass 8 can be done freely to rotate, easily bump, so that noise occurs with retaining foreign matter arc 12, for preventing collision, on described pendulum mass 8 or retaining foreign matter arc 12 both close positions, cushion 14 is set.As Fig. 1, be shown in present embodiment cushion 14 as 3 and be rubber bumper.

As Fig. 5, shown in, in order to make this reminiscences send the sound of different volumes, to adapt to the user of different places, different hearing, on housing 1, have and adjust volume hole 21, and on the correspondence position of adjustment volume hole, adjustment volume switch 13 is set, its switch connects with the resistance of different resistances by connecting different gears, and the resistance of different resistances connects reminiscences with acoustical generator 19 again and sends different volumes.

Switch 13 in the present embodiment also can be used variable resistor instead.Its circuit as shown in Figure 6, one of a variable resistor RP end that terminates at acoustical generator 19 wherein.
