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 17):
The location identification method of  claim 16 , wherein the step of determining the location of the audio output device relative to the first audio receiving device and the second audio receiving device according to the time difference and the amplitude difference between the first characteristic value and the second characteristic value further comprises:\n determining a distance R from the audio output device to a middle point between the first receiving audio device and the second receiving audio device by using the time difference, the amplitude difference, and the predetermined distance; and determining an angle \u03b8 an included angle between a line of the distance and a line of the predetermined distance by using the time difference, the amplitude difference, and the predetermined distance, wherein the distance R and the angle \u03b8 are determined according to the following equation: R = 0.5 \ue89e 2 \ue89e R R 2 + 2 \ue89e R L 2 - D 2 \u03b8 = COS - 1 \ue8a0 ( R R 2 - R L 2 2 \ue89e R \u00d7 D ) .
