Samsung patents headphones that fix noisy music using a server

Samsung describes a device that listens to the sounds around you and identifies specific noises, like a train or a fan. If the noise is too loud, it sends that sound to a server, which returns a clean version of the noise. The device then mixes this clean noise with an inverted version of the ambient sound to cancel it out.

Why it mattersThis approach could make noise cancellation more effective for complex or changing sounds by using cloud processing instead of relying only on the device's own chip.

In the filing’s own words

An electronic apparatus may include a memory, a communication interface configured to perform communication with an external server and at least one processor including processing circuitry, and the at least one processor may be configured to obtain audio data for ambient sound, obtain a target audio signal of a preset type from the audio data, obtain sound quality information of the target audio signal, based on the sound quality information being not equal to or greater than a threshold grade, transmit the target audio signal to the external server through the communication interface, receive a source audio signal corresponding to the target audio signal from the external server through the communication interface, identify a playback time of the source audio signal based on the target audio signal, and provide a synthesized audio signal in which an inversion signal corresponding to the audio data and the source audio signal are synthesized based on the playback time.

What exactly they claim (claim 1)

1. An electronic apparatus comprising: a memory; a communication interface, comprising communication circuitry, configured to perform communication with an external server; and at least one processor comprising processing circuitry, and configured to: obtain audio data for ambient sound; obtain a target audio signal of a preset type from the audio data; obtain sound quality information of the target audio signal; based on the sound quality information being not equal to or greater than a threshold grade, control to transmit the target audio signal to the external server via the communication interface; receive a source audio signal corresponding to the target audio signal from the external server via the communication interface; identify a playback time of the source audio signal based on the target audio signal; and provide a synthesized audio signal in which an inversion signal corresponding to the audio data and the source audio signal are synthesized based on the playback time.
