APPARATUS AND METHOD FOR TRANSMITTING ACOUSTIC SIGNAL

摘要

A sound signal transmitting device outputs a signal of a hypersonic band, which is not less than a set band, by processing an inputted sound signal and converts the signal of the hypersonic band into a hypersonic signal by using multiple hypersonic converters. At this point, as a phase delay is generated in the hypersonic signal outputted from each hypersonic converter by a phase delay layer formed in an output terminal of the hypersonic converters, while hypersonic signals are being transmitted into the air, a sound filed space is formed in a predetermined position.
