Abstract

The utility model relates to a tenant room-leaving reminder, which comprises a touch switch circuit, a sound source generating circuit and an audio power amplifying circuit, wherein the touch switch circuit, the sound source generating circuit and the audio power amplifying circuit are connected in turn, and the touch switch circuit and a metal door handle are connected. When a tenant leaves a room and touches the metal door handle, a heavy load is given to the touch switch circuit, and the touch switch circuit triggers the sound source generating circuit to emit voice prompt audio frequency, and the voice prompt audio frequency reminds a tenant after being magnified by the audio power amplifying circuit.

Description

The dweller is from the room reminiscences

Technical field

The utility model relates to a kind of electronic reminding device, and especially the dweller is from the room reminiscences.

Background technology

The passenger often forgets the thing of oneself easily when leaving the hotel, the passenger is brought inconvenience or loses.If make suitable voice reminder then can effectively improve this situation when the passenger leaves the hotel, but the hotel does not generally have the alarm set of this hommization at present.

Summary of the invention

Do not provide the dweller prompting means easily from the room in order to overcome existing hotel, the utility model provides a kind of dweller speech prompting device from the room, makes suitable prompting when the dweller withdraws from a room, and allows the dweller be not easy to forget thing in the hotel.

The technical scheme that its technical matters that solves the utility model adopts is: the dweller is from the room reminiscences, comprise touch switch circuit, source of sound generation circuit, audio power amplifying circuit, it is characterized in that: touch switch circuit, source of sound generation circuit, audio power amplifying circuit connect successively, and touch switch circuit is connected with the metallic door handle.Touch metallic door when handle when the dweller withdraws from a room, be equivalent to heavy duty of touch switch circuit, touch switch circuit then triggers source of sound generation circuit and sends the voice suggestion audio frequency, and the voice suggestion audio frequency amplifies the back by audio power amplifying circuit and reminds the dweller.

The beneficial effects of the utility model are, can be simple in structure, and with low cost, remind automatically, easy to use, higher utility is arranged.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a theory diagram of the present utility model;

Fig. 2 is an electric structural drawing of the present utility model;

Among the figure, touch switch circuit 1, source of sound generation circuit 2, audio power amplifying circuit 3, metallic door handle 4.

Embodiment

In Fig. 1, the dweller is from the room reminiscences, comprise touch switch circuit 1, source of sound generation circuit 2, audio power amplifying circuit 3, it is characterized in that: touch switch circuit 1, source of sound generation circuit 2, audio power amplifying circuit 3 connect successively, and touch switch circuit 1 is connected with metallic door handle 4.Touch metallic door and shake hands 4 the time when the dweller withdraws from a room, be equivalent to 1 one heavy dutys of touch switch circuit, 1 of touch switch circuit triggers source of sound generation circuit 2 and sends the voice suggestion audio frequency, and the voice suggestion audio frequency amplifies the back by audio power amplifying circuit 3 and reminds the dweller.

In Fig. 2, at ordinary times, work by the transformer feedback formula oscillator that transistor VT1, oscillator coil T etc. forms, bias voltage＜0.65V that trimmer potentiometer RP provides to the VT2 emitter junction, VT2 is in cut-off state, and speech IC A does not have high trigger signal and do not work, and loudspeaker B is noiseless.

When in case staff is run into the metallic door handle, human body connects the collector of VT1 by catch, be equivalent to add a very heavy load that so the VT1 failure of oscillation causes its emitter current to increase, the bias voltage that RP provides to the VT2 emitter junction is thereupon greater than 0.65V to oscillator, VT2 obtains bias current and conducting, A works because of the TG pin obtains high trigger signal, and storage voice telecommunication number in its OUT pin output is after the VT3 power amplification, promote B send loud " please shut the door with your article well! " mezzo-soprano prompting language.After staff left the metallic door handle, VT1 recovered vibration, VT2 ends again, and B only sends a voice sound promptly to be stopped.

Claims

1. the dweller is from the room reminiscences, comprise touch switch circuit (1), source of sound generation circuit (2), audio power amplifying circuit (3), it is characterized in that: touch switch circuit (1), source of sound generation circuit (2), audio power amplifying circuit (3) connect successively, and touch switch circuit (1) is connected with metallic door handle (4).
