Abstract:
A noise cancellation device includes a voice receiving module, a distance measuring module, a noise cancellation module and a speaker module. The voice receiving module is configured to receive a noise. The distance measuring module is configured to send a distance measuring signal to an object, and calculate distance information of the object according to a reflected distance measuring signal reflected by the object. The noise cancellation module is connected to the voice receiving module and the distance measuring module, and is configured to generate a reverse phase signal of the noise according to the noise. The speaker module is connected to the noise cancellation module, and is configured to generate an anti-noise according the reverse phase signal, and sound the anti-noise according to the distance information.

Claim (Index 5):
The noise cancellation device of  claim 1 , wherein the first distance, the second distance, the third distance, the fourth distance, the fifth distance, the first included angle and the second included angle satisfy following equations:\n D 2 2 =D 1 2 +D 4 2 \u22122\u00d7 D 1\u00d7 D 4\u00d7cos(\u03b1) D 3 2 =D 1 2 +D 5 2 \u22122\u00d7 D 1\u00d7 D 5\u00d7cos(\u03b2) wherein D 1  represents the first distance, D 2  represents the second distance, D 3  represents the third distance, D 4  represents the fourth distance, D 5  represents the fifth distance, \u03b1 represents the first included angle, and \u03b2 represents the second included angle.
