![]() Level-trigger Playback: A playback functioning commences whenever switch (SW3) PLAYL is activated and playback halts whenever switch is released. How to Play the recorded messageĮdge-trigger Playback: A playback functioning begins as soon as switch (SW2) PLAYE is clicked or PLAYE pin of IC finds a LOW going potential going above the selected debounced period The REC pin comes with an internal pull-up feature. In case REC is drawn LOW within a playback cycle, the playback right away puts a stop to and recording begins right from the start of the memory. REC normally takes priority over any playback functions. Therefore, the unit automatically makes its way into into standby setting. ![]() After that an End-of-Message (EOM) marker is composed at the finish of message, which allows a succeeding Playback cycle to generate effectively. A record cycle is carried out when REC is drawn to HIGH or complete memory is loaded up. The unit begins recording right from the start from the memory as soon as REC transits through HIGH to LOW and continues at LOW. Recording ceases as soon as the recording button removed or the signal on ICs pin comes back to HIGH. The unit starts off recording anytime REC switch is pressed or recording pin of IC drawn HIGH to LOW and continues at LOW. CN2 (AUD) is current drive output for connecting the circuit with additional audio amplifier. Hook up the 8 ohms 0.5W speaker to LS1 (SPK), implement 5V DC to CN1, and ensure polarity is proper or else it could destroy the IC. Number of Record cycles is around 1 lac times.Approximate massage retention time is 100 years.Low Noise excellent quality voice record/playback.Integrated preset for sampling rates settings.Integrated tact switches for Level trigger Play, Edge trigger Play, and Recording.Simple functions via microswitches switches.AUD current output for operating external power device.Is able to Drive a 8 Ohm speaker directly or even a buzzer.Microphone preamplifier with automatic gain control built in IC.IC normally gets into a standby mode right after a record playback cycle is accomplished.Standby current is around 1 uA and 10 uA maximum with no power LED.Power supply can be within 2.4 to 5.5 VDC. ![]() Specified Power supply input is 5 VDC 100 mA.The unit gets into into standby setting automatically as soon as a recording or a playback operation is accomplished for power saving reasons. It utilizes nominal current in standby function normally 1uA to 100ua (With no power LED). This design works extremely well in number of application like, Interactive Games and booths, Light and sound shows, video gaming devices, educational baby toys, robots, animatronics, lifts/escalators, warning devices, security alarm systems, audio guide, appliances for the home. Message recording and playback is not hard applying on board tact switches. Message length is consumer selectable in ranges from 10 to 20 Seconds based on the sampling rates from 4 KHz to 12 KHz variable through on board potentiometer (preset), presenting you increased versatility in timeframe versus recording quality. The circuit offers excellent audio recording using straightforward procedures. Pre-record recorder-means that the clients provide their sound files,then we programmed them into the recorder and playback them.ģ.Play Mode:Push Button,Light sensor,vibration sensor,motion sensor,PIR (Infrared sensor),shadow SensorĤ.Battery:AA, AAA, AG13, AG10, AG3 and so on environmentalĥ.Shape and Size:Customized (OEM or ODM) or our existed standard sizeħ.As a result, voice or audio data are saved straight to the memory space in their organic form with virtually no compressions as done in digital technique, offering top quality, solid-state audio duplication. Recordable Recorder means that we can record our own message and playback it,there are 6s-240s Recording time. Application :Voice Recorder is our main product,which mainly used by plush toy,stuffer toys,Children toys,Musical toys,Children book and so onĢ.Classification:Recordable voice recorder and Pre-record recorders we can assure you of competive price,high quality,prompt delivery and technology supporting.ġ. Ningbo AST Industry Co.,Ltd has 17 Years Experiences to produce the Voice Recorder,Recordable Sound Box,Plush Toy Voice Recorder,Talking Box,Sound Box,Music Box,Motion Sensors ,Message Box,Voice Cards,Voice Sticker,Squeezing Box,Easy Button,USB Voice Recorders ect.
