Audio frequency generating device and audio frequency generating method

摘要

An audio frequency generating device includes a storage unit, a selecting unit, a processing unit, a first speaker and a second speaker. The storage unit stores at least one chord and each chord includes N fundamental frequencies. The selecting unit is electrically connected to the storage unit. The selecting unit selects M fundamental frequencies from the N fundamental frequencies of at least one of the at least one chord. The processing unit is electrically connected to the selecting unit. The processing unit uses the M fundamental frequencies to generate a first audio frequency. The processing unit uses a frequency difference to adjust each of the M fundamental frequencies to generate a second audio frequency. The first speaker is electrically connected to the processing unit and outputs the first audio frequency. The second speaker is electrically connected to the processing unit and outputs the second audio frequency.
