1. An apparatus, comprising:
- a medicament delivery device including a housing, a medicament container, and a medicament delivery member, the medicament container disposed within the housing, at least a portion of the medicament delivery member disposed within the housing; and
an electronic circuit system coupled to the housing, the electronic circuit system including an audible output device and a cover, a first portion of the audible output device configured to produce a first plurality of sound waves, a second portion of the audible output device configured to produce a second plurality of sound waves having a phase difference with the first plurality of sound waves, the housing and the cover collectively defining an acoustic enclosure, at least one of the housing or the cover defining a first opening, at least one of the housing or the cover defining a second opening,the audible output device configured to be disposed within the acoustic enclosure such that the first plurality of sound waves travels from the first portion of the audible output device to a region outside of the housing via the first opening and the second plurality of sound waves travels from the second portion of the audible output device to the region outside of the housing via the second opening,the second opening spaced apart from the first opening such that the phase difference between the first plurality of sound waves and the second plurality of sound waves is shifted when the first plurality of sound waves exits the first opening and the second plurality of sound waves exits the second opening.
