As you can see there are several ways to do what you are looking to achieve. Here is a breakdown of what I have used in the past and what I would recommend, in the end you will need to decide what you want to do. Most of the options may require so soldering knowledge to make connectors and some level of programming.
Brightsign players: They are reliable and to do what you want possibly the easiest solution, but to just play audio they are too expensive. Also you will need to learn BrightAuthor, its not hard but there is still a learning curve.
Windows PC (Intel NUC, Compute Stick or other types of mini computers): These types of computers can be cheaper, but unlike the Brightsign players they have more flexibility which makes them a better option (in my opinion). Both a PC and Brightsigns can play interactive audio & videos but where the PC will outperform a Brightsign player is in interactive Multimedia, it is far easier to program multimedia an a PC then on a Brightsign; is it far easier to integrate other devices with a PC then a Brightsign, e.g. I use a Micro Arduino to detect motion so I can raise and lower the volume of a video and for about $300 less then an equivalent Brightsign setup which I could not get to work correctly. As you get more complex with BrightAuthor the harder it is to program.
To do an Audio Button push on a PC you can get a USB button interface for about $40.00. This will give you 20 buttons and there are mapped using the keyboard numbers 1-20. There are several ways to program this, you can use a program like Flash or even HTML to play the sounds or you can use a Windows Macro utility that allows you to program any keyboard button to do a task in this case play audio.
Android Mini PC: By far the cheapest option are the Android Mini PCs, I use them as a cheap audio/video players (they cost about $60) I have had one unit playing a video loop for over 3 years without issue and another running a Flash App for about 3 months. There are a bunch of free apps to do the audio and video loops. As for push button, I have not tried it but the USB button interface should work because it is technically a joystick with a lot of buttons. You can also use Flash with AIR to create native Apps or HTML to program these features.
All of the unites have pros and cons but I find that using a PC gives you the most flexibility for future use and access to other technologies that are not available on a Brightsign.
Good luck with your decision

Subject: Push button mechanism to play short audio clips
Hello folks,
Has anyone used a push button mechanism to play short audio clips in a museum exhibit?
We are envisioning the museum viewer seeing images of people and then hearing short audio clips when a button below or next to the image is pushed.
If you use such a mechanism, was it designed in house, or was it outsourced to an exhibition designer.
Thanks,
Daniel
