Method to determine loudspeaker change of placement

A loudspeaker, comprising:

• a cabinet forming a structure of the loudspeaker;
• one or more transducers integrated within the cabinet;
• one or more sensors to produce sensor signals corresponding to detected physical quantities associated with the loudspeaker;
• and
• an orientation and positioning device to determine movement or change to an environment of the loudspeaker based on the sensor signals and generate new drive parameters used to drive the one or more transducers in response to detected movement of the loudspeaker,
• if a level of movement of the one loudspeaker is below a threshold level, the generation of the new drive parameters by the orientation and positioning unit is based on adjustment of old drive parameters,
• if the level of movement of the loudspeaker is above the threshold level, the generation of the new drive parameters by the orientation and positioning unit is based on a full recalibration of the loudspeaker that includes determining the environment of the loudspeaker which includes determining a position of the one or more loudspeakers relative to objects and structures in the listening area,
• wherein the new drive parameters comprise a change in delays and gain values as compared to the old drive parameters.

An article of manufacture for adjusting drive parameters for one or more loudspeakers, comprising:

• a non-transitory machine-readable storage medium that stores instructions which, when executed by a processor in a computer,
• drive, by an audio source, the one or more loudspeakers to output sound based on a first set of drive parameters;
• detect a change to one loudspeaker of one or more loudspeakers based on one or more sensors integrated within the one loudspeaker;
• adjust, in response to the detected change, the first set of drive parameters used to drive the one or more loudspeakers to account for the change of the one loudspeaker, wherein the adjustment produces a second set of drive parameters having a change in delays and gain values as compared to the first set of drive parameters of the one or more loudspeakers;
• and
• if the detected change is a level of movement,
• perform the adjustment in response to the level of movement of the one loudspeaker being below a threshold level, and
• perform a full recalibration of the one or more loudspeakers in response to the level of movement of the one loudspeaker not being below the threshold level, to produce the second set of drive parameters, the full recalibration including determining an environment of the one or more loudspeakers in a listening area wherein determining the environment includes determining a position of the one or more loudspeakers relative to objects and structures in the listening area;
• and
• driving, by the audio source, the one or more loud speakers to output sound based on the second set of drive parameters.
