Amplifier board Notes:
1. subwoofer box and subwoofer power should be large enough
2. subwoofer cabinets is recommended to install a suitable sound-absorbing cotton. So to get a better bass effect, but also with a good subwoofer oh.

ماژول تشخیص گفتار دارای چیپ LD3320 است این چیپ ترکیبی از یک پردازنده تشخیص گفتار به همراه چندین مدار خارجی است که از مبدلAD ، DA ، رابط میکروفون و خروجی صدا تشکیل شده است.

Overview:
Principle: KA-MT15 handsfree intercom module UTC34018 voice speakerphone ASIC production. Its working principle is based on the signal strength of the transmit and receive channels, automatically switches to send or receive job status, half-duplex mode.
Role: in hands-free intercom circuit can effectively suppress feedback caused by the sound of howling, enhance dialogue volume.

Bluetooth Audio Receiver and Playback Module (Bluetooth 4.0)

This MP3 shield board is designed based on VS1053B from VLSI. using this shiled you can plug in your arduino UNO/MEGA direcly as showing in pic, dont' need need to hook up with jumpers, it's becomes more easy to play music compared with the tiny mp3 breakout board. VS1053 is a versatile MP3 codec processor that is capable of decoding a variety of music formats,including Ogg Vorbis/MP3/AAC/WMA/MIDI audio. For the best headphone listening experience, the VS1053 includes EarSpeaker spatial processing which accurately simulates how a room with stereo loudspeakers would sound. In addition to being able to decode all major formats, VS1053 is capable of recording in Ogg Vobis file.
