Title:	Simulated medicament delivery device configured to produce an audible output
Abstract:	An apparatus includes a simulated medicament delivery device and an electronic circuit system. The simulated medicament delivery device includes a housing, and is devoid of a medicament delivery mechanism that causes a medicament to be delivered. The electronic circuit system is coupled to the housing and includes an audible output device and a cover. The housing of the medicament delivery device and the cover of the electronic circuit system collectively define an acoustic enclosure. The audible output device is configured to be disposed within the acoustic enclosure.
