Abstract
Disclosed herein are a speaker device having a built-in microphone and a noise cancellation method using the same. The speaker device having the built-in microphone includes a microphone module picking up sound from a medium to generate a sound pickup signal, a speaker driver transmitting vibration corresponding to a reverse-phase signal of the sound pickup signal to tire medium, and a controller receiving the sound pickup signal from the microphone module, generating the reverse-phase signal of the sound pickup signal, and transmitting the reverse-phase signal to the speaker driver.
Claims17
A speaker device having a built-in microphone comprising:
- a microphone module configured to pick up sound from a medium to generate a sound pickup signal;
- a speaker driver configured to transmit vibration corresponding to a reverse-phase signal of the sound pickup signal to the medium;
- and
- a controller configured to receive the sound pickup signal from the microphone module, generate the reverse-phase signal of the sound pickup signal, and transmit the reverse-phase signal to the speaker driver.
A noise cancellation method through a speaker device having a built-in microphone in which a speaker and a microphone are integrated with each other, the noise cancellation method comprising:
- receiving a sound pickup signal from a medium through the microphone;
- generating a reverse-phase signal of the sound pickup signal;
- and
- transmitting vibration corresponding to the reverse-phase signal to the medium through the speaker having a shape of accommodating the microphone.
