Active Leak Compensation in Small Sized Speakers Using Digital Signal Processing
The frequency response of a small sized speaker unit used in applications such as mobile phones changes substantially with changes in the acoustical load of the speaker. Presently, an acoustical solution is used for reducing the variations in the acoustical load of the speaker. The acoustical solution relies on certain space and volume considerations to function satisfactorily, which are difficult to attain in today’s compact mobile phones. An unconventional approach using digital signal processing to counter such degradation in frequency response is described here.
