  1. APR9600 Voice Recording and Playback System with JRC286D Chip ICStation Mega 2560 Compatible Arduino
  2.  
  3. ICStation team(www.ICStation.com) introduce you this APR9600 voice recording and playback system used in elevator based on the ICStation Mega2560 compatible with Arduino. It uses DC5V voltage to work. When you press the different keys, the loudspeaker will sound that which floor you arrive. This design uses a APR9600 voice chip as the core of the circuit and realizes the function of auto recording and playback. It uses power amplifier chip JRC286D to amplify the audio and enhance the volume. The voice recording and playback circuit is widely used in everyday life. For example, the leaving message and response of the telephone, game machine, and toy voice recording and playback, telling time of the clock or alarm, selling products and control of the household appliance, etc. The designed circuit control is easy ,high-quality sound and big volume. It can be recorded and played for many times and has strong ability of portability. It can be used in other ares for a little modification.The voice recording and playback using the APR9600 chip as the core has the advantage on the price.It is worth of promoting.
