Claim:
1. A wearable communication device, communicates with an electronic device, and the electronic device provides communication data, the wearable communication device comprising: an annular shell including an inner loop, an outer loop and a cavity between the inner loop and the outer loop; a processing module for processing the communication data; a first piezoelectric unit disposed in the cavity; a second piezoelectric unit disposed in the cavity; a driving unit receiving the communication data to trigger the first piezoelectric unit vibrate and generate a corresponding audio signal; and a fixing member disposed in the cavity and connected the first piezoelectric unit and the annular shell, wherein the fixing member disposes in a film-shape, two ends of the piezoelectric unit are connected to the outer loop via the fixing member, respectively, to form an enclosed space; wherein when the second piezoelectric unit receives a sound, the second piezoelectric unit detects a vibration of the sound to generate a corresponding first voltage to form an audio data, and when the second piezoelectric unit is not receiving the sound, the second piezoelectric unit detects a physiological signal of a user, and generates a corresponding second voltage and transmits the second voltage to the processing module.
