Abstract
A sound outputting apparatus to correct sound quality and a method of correcting sound quality thereof includes a speaker to output a sound signal, a remaining vibration detector to detect a remaining vibration of the speaker, a signal processor to generate an offset signal for the detected remaining vibration and output a correction signal in which the input sound signal is mixed with the generated offset signal, and a power amplifier to amplify the correction signal and transmit the correction signal to the speaker. Accordingly, sound quality can be corrected without a mechanical damping device.
Claims22
A sound outputting apparatus to correct sound quality, comprising:
- a speaker to output a sound signal;
- a remaining vibration detector to detect a remaining vibration of the speaker;
- a signal processor to generate an offset signal for the detected remaining vibration and to output a correction signal in which the input sound signal is mixed with the generated offset signal;
- and
- a power amplifier to amplify the correction signal and to transmit the amplified correction signal to the speaker.
A method of correcting sound quality of a sound outputting apparatus having a speaker, the method comprising:
- outputting a sound signal through the speaker;
- detecting a remaining vibration of the speaker;
- generating an offset signal of the detected remaining vibration and outputting a correction signal in which the input sound signal is mixed with the generated offset signal;
- and
- amplifying the correction signal and transmitting the correction signal to the speaker.
A sound outputting apparatus to correct sound quality through a speaker, comprising:
- a remaining vibration detector to detect a remaining vibration of the speaker when the speaker is driven with a sound signal;
- and
- a signal processor to generate a correction signal using the detected remaining vibration and to output the correction signal to the speaker to correct the remaining vibration of the speaker.
A method of correcting sound quality in a sound outputting apparatus having a speaker, the method comprising:
- detecting a remaining vibration of the speaker when the speaker is driven with a sound signal;
- generating a correction signal using the detected remaining vibration;
- and
- outputting the correction signal to the speaker to correct the remaining vibration of the speaker.
A computer-readable medium having executable code stored thereon to perform a method of correcting sound quality in a sound outputting apparatus having a speaker, the method comprising:
- detecting a remaining vibration of the speaker when a sound signal is input to the speaker;
- generating a correction signal using the detected remaining vibration;
- and
- outputting the correction signal to the speaker to correct the remaining vibration of the speaker.
