Because a designer of a Bluetooth earphone is faced with conflicting requirements arising from sensitivity, distortion, bandwidth, and miniaturization, a systematic way of meeting these requirements would be useful. Based on a lumped-parameter model, the design process uses a simulated annealing algorithm, which is essential to a random-search technique. For the microspeaker and associated enclosure, a lumped-parameter model predicts the frequency response. Experimental results of the approach are presented, illustrating that the 3GPP2 standards can be met.
