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 15):
A location identification method for determining a location of an audio output device outputting an audio signal, wherein a waveform of the audio signal is a superposition result of a high frequency signal and an envelope of a characteristic value, comprising:\n receiving the audio signal and sampling the audio signal to generate a plurality of first sampling points by a first audio receiving device with a sampling frequency; receiving the audio signal and sampling the audio signal to generate a plurality of wherein the second audio receiving device is away from the first audio receiving device at a predetermined distance; obtaining a first envelope according to the plurality of first sampling points, wherein the first envelope comprises a first characteristic value; obtaining a second envelope according to the plurality of second sampling points, wherein the second envelope comprises a second characteristic value; and determining the location of the audio output device according to the first envelope of the first characteristic value and the second envelope of the second characteristic value, wherein the envelope, the first envelope, and the second envelope are different from one another.
