Abstract

The utility model relates to a spoon, in particular to a multifunctional speech spoon with auto induction of human body. The spoon of the utility model comprises a plastic main body, an induction chip, a soft-touch switch and a PCB board, a battery, a loudspeaker, a microphone, etc. The induction chip of human body is arranged at the front end of the spoon and is metallic. When the plastic bowl of the spoon is molded, the induction chip is deeply embedded and the induction chip can also be made by all-metallic bowl of the spoon. The induction chip is welded on the PCB board in the middle part by conducting wires. The middle part of a spoon handle is provided with the PCB board, namely, a detection processing circuit of human induction, a central control circuit, a speech processing circuit, a sound recording circuit, a loudspeaker driving circuit and a key control circuit. The spoon of the utility model has the advantage that the spoon can pronounce and has the double functions of entertainment and practicality.

Description

Band is the multifunction speech spoon of induction automatically

Technical field

The utility model relates to a kind of spoon, especially a kind of multifunction speech spoon with the automatic induction of human body.

Background technology

Present existing spoon, great majority are metal, plastic cement, the spoon that variable color etc. are traditional, it is simple in structure, function singleness, the utility model main characteristics is: go to detect by certain electronic circuit when child has a meal, trigger and the control voice, allow it have amusement, practical dual-use function simultaneously, and can encourage, cultivate the initiative that child has a meal.

Summary of the invention:

The utility model purpose provide a kind of can amusement and practical spoon, it has the automatic inducing function of human body, and the contacting of words and spoon when having a meal by detecting child play voice, conversion by button simultaneously can be by by key control speech play and recording playing function.

The utility model is realized like this:

The utility model comprises sheet metal, touch-switch and pcb board, battery, loudspeaker and the miaow head of plastic cement main body, human body sensing, the front end of spoon is a plastic cement spoon bowl part, it is inner that the sheet metal of human body sensing is embedded in spoon bowl, sensing chip by wire bonds on the pcb board of kettleholder inside.There is pcb board the inside of kettleholder, and pcb board comprises: human body sensing detects treatment circuit, central control circuit, speech processing circuit, recording circuit, drive circuit of loudspeaker and key control circuit.Also have waterproof speaker, waterproof miaow head in the middle of the kettleholder.The end of kettleholder is battery, battery sheet and battery door water proof ring and fixed screw.

The utility model can switch three kinds of mode producing voice by button:

Key control circuit comprises following three kinds of button switch modes:

A, automatic induction make spoon produce voice;

B, make spoon produce voice by key control;

C, play voice by key control recording back.

Band described in the utility model its inductive mode of multifunction speech spoon of induction automatically has: a, noncontact induction; B, contact inductive mode.

Speech processing circuit of the present utility model is the CPU of band phonetic function, its work is as follows: the human body sensing sheet that touches the spoon bowl when human body just has an induced signal, this signal removes to control voice after handling through CPU, realizes recording, playback automatically, responds to the switching of playback automatically with button simultaneously.

The utility model has the advantages that spoon induction human body and automatic pronunciation, have amusement, practical dual-use function, and can encourage, cultivate the initiative that child has a meal.

Description of drawings:

1, Fig. 1 is a front view of the present utility model.

2, Fig. 2 is a profile of the present utility model.

3, Fig. 3 is a circuit diagram of the present utility model.

Among the figure, 1, plastic cement spoon bowl; 2, sensing chip; 3, waterproof soft plastic; 4, touch-switch and pcb board; 5, loudspeaker and miaow head; 6, main body upper casing; 7, main body lower casing; 8, battery cover; 9, battery; 10, collision mat.

The specific embodiment:

As shown in Figure 2, present embodiment comprises plastic cement main body, sensing chip 2, touch-switch and pcb board 4, battery 9, loudspeaker and the miaow head of being made up of plastic cement spoon bowl 1, main body upper casing 6, main body lower casing 75 etc.

The front end of spoon is the human body sensing chip, and this sensing chip is a metal, and is in the moulding of plastic cement spoon bowl that it is inside buried.Sensing chip by wire bonds on the pcb board of middle part.The centre position of kettleholder be pcb board promptly: human body sensing detects treatment circuit, central control circuit, speech processing circuit, recording circuit, drive circuit of loudspeaker and key control circuit.Also have waterproof speaker, waterproof miaow head in the middle of the kettleholder.Pcb board is fixed by the plastic cement post, and loudspeaker and miaow head bonding wire back to the pcb board is played glue and fixed, touch button touch function and water-proof function is to accomplish by the post forming of soft plastic.The end of kettleholder is three button cells, battery sheet and battery door water proof ring and fixed screw.Battery is withheld in battery case the inside, and wire bonds battery sheet adds a water proof ring in order to the power supply pcb board around battery case, and the gland battery door screws, and is mainly used in that battery is fixed and waterproof.

The 2nd pin of the circuit theory of the utility model specific embodiment: CPU connects a touch-switch and is used for the function selection to power supply, after start powers on, circuit is in resting state, when pressing touch-switch, circuit enters duty, and trigger and to have cured the voice that are pre-stored in the CPU, voice amplify the back by the CPU internal power and drive the loudspeaker pronunciation from 20,23 pin, and whenever can circulate successively to trigger by touch-switch CPU has cured the voice that are pre-stored in the CPU and makes it pronunciation.

Press touch-switch after 2 seconds when long, circuit enters human body and responds to the phonological working state that triggers automatically, this moment is after human body touches plastic cement spoon bowl or metal spoon bowl, the electric capacity that a contact will be arranged on sensing chip, this electric capacity is added to the 11 and 12 pin two ends of CPU through R1, C1, R2, this moment, CPU just can calculate the changes in capacitance value, after CPU calculates capacitance variations, just trigger to have cured being pre-stored in voice in the CPU, voice amplify the back by the CPU internal power and go to drive the loudspeaker pronunciation from 20,23 pin.

When vice-minister again by touch-switch after 2 seconds circuit enter the recording duty, circuit is enrolled needed voice by the loudspeaker of 20,23 pin, is stored in CPU inside, touches by touch-switch and plays the voice of being recorded.

Each length is pressed touch-switch after 2 seconds, and circuit will carry out work and switch under above three kinds of patterns.More than three kinds of patterns as long as do not do any triggering in this at five minutes, circuit just enters the auto sleep state this moment.Available touch-switch wake-up circuit work.
