Detailed description of the invention

(embodiment 1)

See Fig. 1 and Fig. 2, a kind of voice cloth doll of the present embodiment, including power supply, microphone, speaker, APR9600 chip, Microswitch, oscillation resistance and double contact switch K1；Described APR9600 built-in chip type amplifying circuit, filtering circuit, sample circuit And flash memory；Described power supply, microphone, speaker, microswitch and oscillation resistance are all connected with APR9600 chip；Described Microswitch includes eight；The resistance of described oscillation resistance is 44K Europe or 24K Europe.Described double contact switch and microphone and micro- Dynamic switch connects.Described APR9600 chip 1-6 foot and 8-9 foot connect one end of microswitch M1～M8, microswitch M1 respectively ～the other end of M8 is with connecing power supply and one end of K1-2 contact of K1, microswitch M1 the most simultaneously；APR9600 chip 7 foot passes through Resistance R9 ground connection, APR9600 chip 12 foot, 13 feet and 26 feet connect power supply ground, also by resistance R4 while of APR9600 chip 9 foot Meeting power supply VCC, APR9600 chip 23 foot meets power supply VCC by R5, and APR9600 chip 24 foot meets power supply VCC by R2, APR9600 chip 25 foot meets power supply VCC by R3, and APR9600 chip 27 foot connects power supply VCC, simultaneously APR9600 chip by R1 27 feet connect the other end of the K1-2 contact of double contact switch K1, and APR9600 chip 28 foot, 16 feet and 11 feet meet power supply VCC, APR9600 chip 14 foot and 15 feet connect speaker, series capacitance C1 between APR9600 chip 20 foot and 21 feet, APR9600 chip 17 feet are connected with microphone MIC by electric capacity C3 by electric capacity C2,18 feet, and microphone MIC connects power supply VCC by resistance R6 simultaneously, One end of the K1-1 contact of double contact switch K1 is connected, another termination electricity of the K1-1 contact of double contact switch K1 by resistance R7 Seedbed, APR9600 chip 19 foot electric capacity C4 in parallel, disciple's anger R8 connect the K1-1 contact of double contact switch K1 and connect power supply ground One end.

The principle of the present embodiment is: APR9600 built-in chip type amplifying circuit, filter circuit, sample circuit and flash Device FLASHROM, during recording, external audio signal is entered by microphone MIC, and amplifying circuit carries automatic gain control, can be by outward Connecing resistor-capacitor unit and set response speed and gain ranging, filtered circuit, sample circuit are stored in special in analog quantity mode after processing In flash memory FLASHROM.The recording playback time of APR9600 chip is 32～60 seconds, and the oscillation resistance R9 that the 7th foot is external Size relevant.When R9 takes 44K, sample frequency is relatively low, and the frequency band of record/playback is 2.1KHz, up to 60 seconds recording playback time；When When taking 24K, sample frequency is higher, and the frequency band of record/playback is 4KHz, can match in excellence or beauty with the tonequality of phone, and the now recording playback time is only 32 seconds.Oscillation resistance R9 can time as required and acoustical quality step-less adjustment.APR9600 chip by arranging 24,25, The level of 9 feet can realize parallel two-stage nitration, four sections, eight sections of controls, has been connected into parallel eight sections as shown in Figure 1.As long as pressing fine motion Arbitrary key in switch M1～M8, APR9600 chip will the sound reproduction one time of this section typing, if during playback again By stopping the most immediately, do not put chip by this section of loop play if pressed & hold.The each period when parallel control state The most identical, thus in eight sections the time of each the most not can exceed that 7.5 seconds (oscillation resistance is 44K).Eight fine motions of M1～M8 are opened Close the diverse location being separately mounted to cloth doll, should be able to reliably connect when touching.As long as microphone MIC loop switches on power will disappear Consume certain electric current, survey about 0.3mA, the life-span of battery can be affected, so adding a double contact switch K1, as K1-1, K1- 2 disconnect, and microphone MIC loop disconnects and not working, and 27 pins connect high level by resistance and put 1, and APR9600 chip is playback pattern； When K1-1, K1-2 close, microphone loop works, 27 pins connect low level and set to 0, and APR9600 chip enters recording state, at this moment presses Live in M1 and i.e. hear that a sound of " ticking " represents the recording that can carry out first paragraph, when unclamping button, hear again that a sound of " ticking " represents record Sound terminates, and can carry out remaining recording of seven sections by same method.

Particular embodiments described above, has carried out entering one to the purpose of this utility model, technical scheme and beneficial effect Step describes in detail, be it should be understood that and the foregoing is only specific embodiment of the utility model, is not limited to this Utility model, all within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. done, all should wrap Within being contained in protection domain of the present utility model.
