摘要： This invention involves the integration of piezoelectric speaker panels (66, 67) and microphones (68) into a personal computer (65) with a sound card to form a novel multimedia computer. In addition noise cancellation electronics and algorithms are also applied to enhance performance of a voice recognition system included in the computer.
