Abstract

The utility model relates to an automatic voice calling-for-help device. The utility model is composed of a box body, a universal mercury switch, a horn, a double-pole power switch, a timing circuit, an alarm circuit, a power amplification circuit, a solid recording circuit, etc. The utility model does not produce sound when the utility model is vertically placed, and the utility model automatically produces sonorous alarm sound firstly when an inclination angle to any direction exceeds 45 DEG and then automatically transfers into voice playing so that the pre-recorded calling-for-help voice is clearly and completely played. The utility model is especially suitable for the alone outgoing of old and weak people who can use the utility model to attract calling-for-help people in case of burst disease symptoms.

Description

The automatic speech two's complementer

The utility model belongs to a kind of warning device, relates to a kind of automatic speech two's complementer.

At present, the use of these devices some portable emergency treatment alarms appearred, on the market.Can reduce particularly coronary heart disease patient's sudden death rate of some high risk patients relatively.But the shortcoming of these devices is: the warning purpose is unclear, and specific aim is poor, and in the face of the burst patient, which kind of disease the passerby people that do not know to fall ill suffers from, and how to assist to rescue, thereby has delayed the time in vain, has caused lifelong sorry.

The purpose of this utility model provides a kind of audio alert that passes through can know narration warning purpose automatic speech two's complementer.

For achieving the above object, the utility model is taked following design proposal: the automatic speech two's complementer is by box body, universal mercury cut-off, loudspeaker, double-pole power switch, compositions such as timing circuit, warning circuit, power amplifier and solid recording circuit.Energized when described universal mercury cut-off surpasses 45 ° at the angle of inclination, wherein the output terminal of timing circuit connects warning circuit, and the output of warning circuit connects power amplifier, and the output of power amplifier connects double-pole power switch and loudspeaker; The output terminal of timing circuit also connects a transistor simultaneously, and the transistorized playback end of penetrating level output connection solid recording circuit, the audio signal output end of solid recording circuit is connected with the input end of power amplifier by an electric capacity.

Sounding not when this voice help device is vertically placed; When surpassing 45 ° as the pitch angle to either party, two's complementer sends loud and clear chimes of doom earlier automatically, changes playback afterwards automatically over to, the voice of seeking help of typing is in advance known intactly play back.Use when the people that this device is specially adapted to get old and weak goes out separately, when contingency burst illness, can attract the seeking help person by this two's complementer, and can tell realizingly how others should succour patient.As having this device at one's side, may save life crucial moment.

Fig. 1 is an electrical schematic diagram of the present utility model

Below in conjunction with accompanying drawing the utility model is further elaborated.

In Fig. 1, the automatic speech two's complementer is made up of box body, universal taps, loudspeaker, double-pole power switch, timing circuit, warning circuit, power amplifier and solid recording circuit etc.When described universal mercury cut-off 1 surpasses 45 ° at the pitch angle, connect double-pole power switch 2.The output terminal (three-prong of NE555) of the timing circuit of being made up of R1, R2, W1, D1, D2, C1 and integrated circuit (IC) 1 (NE555) connects warning circuit IC2, and the IC2 output terminal connects capacitor C 2 back connection power amplifier IC3 (LM386), and the output terminal of power amplifier connects double-pole power switch 2 and loudspeaker 3 by capacitor C 4; The output terminal of integrated circuit (IC) 1 also is connected with a transistor G1 simultaneously, its emitter-base bandgap grading output connects the playback end (24 pin of ISD1420) that capacitor C 11 backs connect solid recording circuit IC4 (ISD1420), and the audio signal output end of IC4 (the 15 pin of ISD1420) connection capacitor C 3 backs are connected with the input end of power amplifier IC3.

This circuit working principle is summarized as follows:

Universal mercury cut-off 1 is vertically fixed in the box body, in case surpass 45 ° to the angle of inclination of any direction, mercury cut-off 1 is energized switch 2 and power supply, makes circuit enter duty.At this moment the output of NE555 (three-prong) is for just in the timing circuit, and after this signal entered warning circuit IC2, its output signal entered power amplifier IC3 through capacitor C 2, and the signal after being amplified by IC3 enters loudspeaker 3 through capacitor C 4, thereby sends loud and clear chimes of doom.After several seconds, the three-prong of IC1 loses noble potential (voltage is O), transistor G1 conducting, and emitter-base bandgap grading is high electronegative potential, and enters the playback end (24 pin) of IC4 by capacitor C 11.And the audio signal output end of IC4 (15 pin) enters the input end (two pin) of power amplifier IC3 by capacitor C 3, and the sound signal that is exaggerated is emitted by loudspeaker.At this moment passerby can hear clear complete emergency voice, is convenient to sue and labour to patient.

Above-mentioned IC4 is a solid recording circuit, and its 24 pin is the playback end, and 27 pin are the recording end, and a button 5,4 respectively is equipped with at two ends.As long as this circuit has powered battery, can record at any time, playback, therefore also can do study, device is used with reading, leaving a message.When preparing to go out with it as the voice help device, should push button 4, the complete clearly typing of the voice of will seeking help in advance pushes button 5 again, checks recording effect by playback, can carry.

From the chimes of doom of original state to the switching time of sending audio alert, the time constant decision of forming by R1, R2, W1, D1, D2, C1.
