The invention discloses a device capable of receiving and sending various alarming messages and conducting acoustic code word communication, which comprises a channel modulator/demodulator, a channel coding/decoding module, a data coding/decoding module, an LCD (liquid crystal display) module, a microprocessor control module, a panel operating and displaying interface module, an analog voice/data voice conversion module, a digital alarming signal generator, a transmitter interface and an audio output interface. When a radiofrequency antenna receives an alarm and an alarm message, the channel modulator/demodulator conducts radiofrequency demodulation to the received signal firstly, then the channel coding/decoding module decodes the channel signal, the data coding/decoding module decodes the transmission data, and the LCD module displays the alarm and the alarm message. The device not only can receive alarms or alarming messages, but also can give an alarm or an alarm message, can display the specific content of the alarms or alarming messages by audio or characters, and also can be used for acoustic code communication in need.
