The second sound device 15 receives the sound signal of the second channel 112 through the output module 117 and plays an audio of the second channel 1105 according to the sound signal of a second channel 112. In the embodiment, the first channel is a right channel and the second channel is a left channel. In addition, it is to be noted that the first sound device 13 and the second sound device is located at the wrong position to play the audio of the right channel 1103 and the audio of the left channel 1105.

Referring to FIG. 3, a reference signal of the right channel 114 is transmitted to the output module 117 from the processor 111. The first sound device 13 receives the reference signal of the right channel 114 through the output module 117 and plays a reference audio of the right channel 1140 according to the reference signal of the right channel 114. The first sound-receiving module 113 receives the reference audio of the right channel 1140 and generates a first input signal 116a when the reference audio of the right channel 1140 is played by the first sound device 13. The second sound-receiving module 115 also receives the reference audio of the right channel 1140 and generates a second input signal 116b when the reference audio of the right channel 1140 is played by the first sound device 13. Then, the first input signal 116a is transmitted to the processor 111 by the first sound-receiving module 113 and the second input signal 116b is transmitted to the processor 111 by the second sound-receiving module 115.

A receiving time span of the first input signal 116a and the second input signal 116b is calculating by the processor 111 when the two signals are received.

A receiving time span of the third input signal 220a and the fourth input signal 220b is calculating by the processor 211 when the two signals are received. Referring to FIG. 8, the receiving time of the third input signal 220a is late than the receiving time of the fourth input signal 220b due to the second sound-receiving module 215 is located adjacent to the second sound device 15. Therefore, the processor 211 determines that the first sound device 13 and the second sound device 15 are located at the correct position to play the audio of the right channel and the left channel.

Then, an alert signal 222 is generated by the processor 211 due to the result of the receiving time span between first input signal 216a and the second input signal 216b and the receiving time span between third input signal 220a and the fourth input signal 220b is contradiction.

Finally, the display unit 219 receives the alert signal 222 from the processor 211. Alert information is displayed on the display unit 219 to notice the user that the first sound-receiving module 213 and the second sound-receiving module are located at the wrong position.

The processor 311 compares the input signal 314 with a predetermined signal after the input signal 314 is received. In the embodiment, the basis for comparison is the decibel (dB) of the sound (corresponding to the input signal 314 and the predetermined signal). The processor 311 determines that the headset is worn incorrectly when the input signal 314 is less than the predetermined signal.

Referring to FIG. 14, after the judgment of the processor 311, the sound signal of the right channel 310 and the sound signal of the left channel 312 are adjusted by the processor 311 so that the first sound device 33 receives the sound signal of the left channel 312 and plays the audio of the left channel 3105 and the second sound device 35 receives the sound signal of the right channel 310 and plays the audio of the right channel 3103.

An electronic apparatus is electrically connected to a first sound device and a second sound device, wherein the first sound device receives a sound signal of a first channel and plays an audio of the first channel according to the sound signal of the first channel, and the second sound device receives a sound signal of a second channel and plays an audio of the second channel according to the sound signal of the second channel, comprising: an output module that is electrically connected to the first sound device and the second sound device to transmit the sound signal of the first channel and the sound signal of the second channel;a processor that is electrically connected to the output module and outputs a reference signal of the first channel to the first sound device through the output module to plays a reference audio of the first channel;a first sound-receiving module that is electrically connected to the processor for receiving the reference audio of the first channel so as to generate a first input signal; anda second sound-receiving module that is electrically connected to the processor for receiving the reference audio of the first channel so as to generate a second input signal,wherein the processor receives the first input signal and the second input signal for calculating a receiving time span between the first input signal and the second input signal so as to control the first sound device to receive the sound signal of the second channel and control the second sound device to receive the sound signal of the first channel when the receiving time of the first input signal is late than the receiving time of the second input signal.
6. The electronic apparatus defined in claim 5, wherein the processor further generates a reference signal of the second channel for transmitting to the second sound device through the output module so that the second sound device plays a reference audio of the second channel according to the reference signal of the second channel, and the first sound-receiving module further receives the reference audio of the second channel to generate a third input signal, the second sound-receiving module further receives the reference audio of the second channel to generate a fourth input signal that the third input signal and the fourth input signal are transmitted to the processor for calculating a receiving time span between the third input signal and the fourth input signal so as to generate an alert signal when the receiving time of the third input signal is late than the receiving time of the fourth input signal.
7. The electronic apparatus defined in claim 6, further comprising a displaying unit that is electrically connected to the processor for receiving the alert signal so as to display alert information.
8. A sound signal adjustment method cooperating with an electronic apparatus, which is electrically connected to a first sound device and a second sound device, wherein the first sound device receives a sound signal of a first channel and plays an audio of the first channel according to the sound signal of the first channel, and the second sound device receives a sound signal of a second channel and plays an audio of the second channel according to the sound signal of the second channel, comprising the steps of: generating a reference signal of the first channel;transmitting the reference signal of the first channel to the first sound device so as to play a reference audio of the first channel according to the reference signal of the first channel;receiving the reference audio of the first channel by the first sound-receiving module so as to generate a first input signal;receiving the reference audio of the first channel by the second sound-receiving module so as to generate a second input signal;receiving the first input signal and the second input signal;calculating a receiving time span between the first input signal and the second input signal; andcontrolling the first sound device to receive the sound signal of the second channel and controlling the second sound device to receive the sound signal of the first channel when the receiving time of the first input signal late than the receiving time of the second input signal.
9. The electronic apparatus defined in claim 8, further comprising the steps of: generating a reference signal of a second channel;transmitting the reference signal of the second channel to the second sound device so as to play a reference audio of the second channel according to the reference signal of the second channel;receiving the reference audio of the second channel by the first sound-receiving module so as to generate a third input signal;receiving the reference audio of the second channel by the second sound-receiving module so as to generate a fourth input signal;receiving the third input signal and the fourth input signal;calculating a receiving time span between the third input signal and the fourth input signal; andgenerating an alert signal when the receiving time of the third input signal late than the receiving time of the fourth input signal.
10. The electronic apparatus defined in claim 9, further comprising the steps of: receiving the alert signal; anddisplaying an alert information according to the alert signal.
