You can change the duty cycle of the speaker in order to conserve power. By default, the duty cycle is 01/04 which means the
speaker is active 25% of the time when on, yielding a 75% reduction in speaker power use. Because a duty cycle is a timed
period, changing the duty cycle will have an effect on the audio frequency of the speaker. We recommend leaving this value at
it's default.
