Abstract:
A location identification device, adopted in an audio output device outputting an audio signal, includes a first audio receiving device, a second audio receiving device, and a processor. The first audio receiving device samples the audio signal by a sampling frequency to generate first sample points. A waveform of the audio signal is a superposition result of a high frequency signal and an envelope. The second audio receiving device, which is away from the first audio receiving device at a predetermined distance, samples the audio signal by the sampling frequency to generate second sample points. The processor obtains the first envelope of a first characteristic value and the second envelope of a second characteristic value for identifying a location of the audio output device according to a time difference and an amplitude difference between the first characteristic value and the second characteristic value.

Claim (Index 12):
The location identification device of  claim 8 , wherein a ratio of a product of the sampling frequency by the predetermined distance to a sound speed is greater than 1.5.
