Abstract: A speaker apparatus, method, and system with a user selectably expandable chamber is provided. The chamber in its expanded state enhances the speaker's acoustical properties using a relatively stiff back plate of the speaker apparatus. The chamber in its collapsed state provides a thin profile for increased portability or low profile mounted solutions. The speaker is compatible with current electronics and may magnetically attach to a target surface such as a surface of a handheld device. The target surface may effectively supplement the stiffness of the back plate.

Abstract: A loudspeaker includes a plurality of electro-acoustic drivers that are configured to be positioned so that an axis running through an acoustic center of the drivers is one of a substantially straight line, J-shape, reverse J-shape, and C-shape. The loudspeaker also includes at least one sensor to detect a configuration of the plurality of electro-acoustic drivers, and a processing device configured to automatically adjust one or more of an equalization and a gain applied to an audio signal output through the electro-acoustic drivers based on the detected configuration.

Abstract: Feedback is reduced by routing an input signal through a kick gate that opens for a predetermined time period then closes. The gate may be kept closed for a predetermined minimum time period before being allowed to open again. The gate is triggered open based on the input signal and may include a plurality of triggering conditions.

Abstract: An equalizer/mixer receives an input signal from a musical source and equalizes the input signal based on the musical source using equalization parameters associated with the musical source. User-adjustable equalization controls may be applied where the equalization parameters defining the controls are associated with the musical source.
