Abstract

A sound adjustment method is disclosed. The sound adjustment method includes the following the steps: receiving a sound adjustment command; receiving a right channel sound signal and a left channel sound signal; selecting a corresponding adjustment mode according to the sound adjustment command and processing the right channel sound signal and the left channel sound signal based on the adjustment mode to generate a right channel first sound signal and a left channel first sound signal, wherein different adjustment modes have different intensity adjustment levels; shifting the frequency of the right channel first sound signal by X Hz to generate a right channel second sound signal and shifting the frequency of the left channel first sound signal by Y Hz to generate a left channel second sound signal, wherein 0.5≤|X−Y|≤100; outputting the right channel second sound signal and the left channel second sound signal.

Claims (21)

1. A sound adjustment method, comprising the following steps:

receiving a sound adjustment command;

receiving a right channel sound signal and a left channel sound signal which is different from the right channel sound signal;

selecting a corresponding adjustment mode according to the sound adjustment command and processing the right channel sound signal and the left channel sound signal based on the adjustment mode to generate a right channel first sound signal and a left channel first sound signal, wherein different adjustment modes have different intensity adjustment levels; when the adjustment mode has a greater intensity adjustment level, the right channel first sound signal is more similar to the left channel first sound signal; when the adjustment mode has a smaller intensity adjustment level, the right channel first sound signal is less similar to the left channel first sound signal;

when the adjustment mode has the largest intensity adjustment level, the right channel first sound signal is an equal mixture of the right channel sound signal and the left channel sound signal and the left channel first sound signal is also an equal mixture of the right channel sound signal and the left channel sound signal;

shifting the frequency of the right channel first sound signal by X Hz to generate a right channel second sound signal and shifting the frequency of the left channel first sound signal by Y Hz to generate a left channel second sound signal, wherein 0.5≤|X−Y|≤100; and

outputting the right channel second sound signal and the left channel second sound signal.

2. The sound adjustment method as claimed in claim 1 , wherein when the adjustment mode has the smallest intensity adjustment level, the right channel first sound signal is equal to the right channel sound signal and the left channel first sound signal is equal to the left channel sound signal.

3. The sound adjustment method as claimed in claim 1 , wherein |X|=|Y|.

4. The sound adjustment method as claimed in claim 1 , wherein X=0 and Y≠0.

5. The sound adjustment method as claimed in claim 1 , wherein X≠0 and Y=0.

6. A sound adjustment device, comprising:

a command receiving end, which receives a sound adjustment command;

a sound signal input end, which receives a right channel sound signal and a left channel sound signal which is different from the right channel sound signal;

a signal processing module, which is electrically connected to the command receiving end and the sound signal input end and selects a corresponding adjustment mode according to the sound adjustment command and processes the right channel sound signal and the left channel sound signal based on the adjustment mode to generate a right channel first sound signal and a left channel first sound signal, wherein different adjustment modes have different intensity adjustment levels; when the adjustment mode has a greater intensity adjustment level, the right channel first sound signal is more similar to the left channel first sound signal; when the adjustment mode has a smaller intensity adjustment level, the right channel first sound signal is less similar to the left channel first sound signal; when the adjustment mode has the largest intensity adjustment level, the right channel first sound signal is an equal mixture of the right channel sound signal and the left channel sound signal and the left channel first sound signal is also an equal mixture of the right channel sound signal and the left channel sound signal;

a frequency adjustment module, which shifts the frequency of the right channel first sound signal by X Hz to generate a right channel second sound signal and shifts the frequency of the left channel first sound signal by Y Hz to generate a left channel second sound signal, wherein 0.5≤|X−Y|≤100; and

a sound signal output end, which is electrically connected to the frequency adjustment module and outputs the right channel second sound signal and the left channel second sound signal.

7. The sound adjustment device as claimed in claim 6 , wherein when the adjustment mode has the smallest intensity adjustment level, the right channel first sound signal is equal to the right channel sound signal and the left channel first sound signal is equal to the left channel sound signal.

8. The sound adjustment device as claimed in claim 6 , wherein |X|=|Y|.

9. The sound adjustment device as claimed in claim 6 , wherein X=0 and Y≠0.

10. The sound adjustment device as claimed in claim 6 , wherein X≠0 and Y=0.
