Full-duplex 2.4G walkie-talkie solution
In view of the problems of poor anti-interference and short transmission distance of RF intercom that are common in the market at present, Zochuang and Taiwan Songhan jointly developed and cooperated to develop a new 2.4G children's intercom solution. The current solution mainly uses Songix's new IC model SNC7648 JiaZuChuang exclusive research and development of 2.4G packaged IC.
SNC7648 is a 16-bit CMOS monolithic DSP with 12-bit SAR ADC, 12-bit push-pull DAC, built-in LDO voltage regulator and SPI flash controller. Its internal 48KW ROM contains Songix's application library or can develop custom DSP functions. The target application includes high-quality audio compression algorithm, long-time recording/playback, real-time sound changing effect and Sonix tone detection technical support for the transmitter and receiver.
advantage:
1. One-to-one transmission, 2.4g intercom, the sound quality is very clear, unlike RF intercom that interferes with the sound source.
2. BOM cost is competitive in the same industry market.
3. In addition to the original voice, it also supports 5 voice changing modes Echo, male voice, female voice, robot, Iron Man, real-time voice change transmission. The unique sound change function attracts children's attention and increases fun.
4. The 2.4g antenna can be made small and applied to various prototypes, such as children's walkie-talkies, watches, and some wearable devices.
