Method and system of varying mechanical vibrations at a microphone

A system comprising:

• a microphone;
• a first speaker configured for receiving a first input signal and generating a first vibration force;
• a signal transformation unit receiving the first input signal and performing a signal transformation thereon to produce one or more transformed input signals for varying an amount of mechanical vibration at the microphone;
• and
• a second speaker configured for receiving one of the one or more transformed input signals and generating a second vibration force;
• wherein:
• a combination of the first vibration force and the second vibration force varies the amount of mechanical vibration at the microphone.

A method for varying an amount of mechanical coupling between at least one microphone and one or more speakers in a speakerphone comprising:

• receiving an input signal;
• sending a copy of the input signal to a first speaker;
• determining if a signal transformation is needed for the input signal to vary an amount of mechanical coupling;
• upon determining that the signal transformation is needed, performing the signal transformation on the input signal to produce a transformed input signal;
• and
• transmitting the transferred input signal to a second speaker;
• wherein the first speaker generates a first vibration force, the second speaker generates a second vibration force, and a combination of the first vibration force and the second vibration force varies the amount of mechanical coupling between the at least one microphone and the one or more speakers.
