The apparatus of claim 1, wherein the audible output device is a speaker configured to output an audible output having a sound pressure level greater than about 61 decibels. 6. The apparatus of claim 1, wherein the audible output device is a speaker configured to output an audible output having a sound pressure level greater than about 61 decibels at a distance of about 6 inches from the speaker. 7. The apparatus of claim 1, wherein the audible output device is a speaker configured to output an audible output having a sound pressure level greater than about 61 decibels within a distance of about 20 feet from the speaker. 8. The apparatus of claim 1, wherein: the electronic circuit system is configured to output to the audible output device an electronic signal having a power of less than 100 milliwatts; and the audible output device is configured to output a recorded speech output in response to the electronic signal, the recorded speech output having a sound pressure level greater than about 61 decibels. 9. The apparatus of claim 1, wherein the audible output device is a speaker, the housing includes a spacer configured to be disposed adjacent the speaker such that a front portion of the speaker is in contact with a portion of the cover. 10. The apparatus of claim 1, wherein at least a portion of the housing that defines the acoustic enclosure includes a flexible wall. 11. An apparatus, comprising: a medicament delivery device including a housing and a medicament container, the medicament container disposed within the housing; and an electronic circuit system coupled to the housing, the electronic circuit system including a speaker and a cover, the speaker includes a front portion and a back portion, the front portion of the speaker configured to output a first audible output including a first plurality of sound waves, the back portion of the speaker configured to output a second audible output including a second plurality of sound waves, the cover defining a first exit path through which the first plurality of sound waves is configured to travel from the front portion of the speaker to a region outside of the housing, the housing defining at least a portion of a second exit path through which the second plurality of sound waves is configured to travel from the back portion of the speaker to the region outside of the housing, a length of the first exit path different from a length of the second exit path such that the first plurality of sound waves is substantially in phase with the second plurality of sound waves when the first plurality of sound waves exits the first exit path and the second plurality of sound waves exits the second exit path. 12.
