SIGNAL PROCESSING FOR ELIMINATING SPEAKER AND ENCLOSURE BUZZ |
| 摘要 |
An electronic device for buzz reduction is described. The electronic device is to be used with a speaker driver that is built onto an enclosure and is to be driven by an audio signal which could cause the enclosure to produce buzz. The electronic device includes a filter that is to attenuate a frequency component of the audio signal before driving the speaker driver. The electronic device also includes a controller that is to configure the filter to attenuate the frequency component of the audio signal in response to determining that strength of the audio signal at the frequency component exceeds a threshold. Other embodiments are also described and claimed. |
