Audio Communication Cases

Project Overview

Many kids are unable to speak and use buttons to talk. When they click a button it vocalizes a pre recorded message. These buttons come in many forms with various different use cases (ie. many buttons for a person with more fine motor skills versus a single button for someone with less). One main problem with these buttons is that they don't come with a good way to secure them to a mount. Additionally, like many things, they break. To fix this, I designed and 3d printed cases for three different types of audio communication buttons that are easily mountable and keep the devices safe.

Case 1: Simple Individual Communicator

This communication device is used by one student to say one or two different things. It is activated by placing a finger in the indented rectangle.

Case 2: Complex Individual Communicator

This communication device is used by one student to say many different things. It is activated by clicking a button and each button says different things.

Case 3: Class Communicator

This communication device only says one thing. OUSD wants to be able to permanently attach it to the wall in classrooms to say various things. One thing it might say when attached near an exit door is "I'm going to the bathroom."

Case 1 Design Considerations

Mounting

I took a picture of the mount that I was given so that I could trace the holes in cad.

Opening

There is a cap to the case which slides in and out and locks in place as it gets pushed further in due to reduced tolerances.

Removal

There is a hole at the bottom of the case which allows someone to easily push the device out of its case.

Case 2 Design Considerations

Mounting

This is mounted the same as Case 1.

Opening

Like Case 1 there is a cap to the case which slides in and out and locks in place as it gets pushed further in due to reduced tolerances.

Removal

Again like Case1, the hole at the bottom allows someone to easily push the device out of its case.

Extra Plate

There is an extra plate which makes it harder to press multiple buttons at the same time.

Case 3 Design Considerations

Mounting

One way to mount this button to the wall is using the two countersunk holes on the cap. This method allows the button and main case to be removed from the wall while the cap remains on the wall. Removing the case allows a new message to be recorded.

Mounting

The other way to mount this to the wall is using the four holes on the main case. With this method the case cannot be easily removed from the wall which precludes tampering from kids.

Removal and Opening

The cap slides on and due to lower tolerances as it gets pushed further, it stays on. There are two indents in the cap which facilitate easy opening. The hole for the red button allows someone to easily push the device out of its case.

Charging

There is a hole in the case where the port of the audio device is which allows is to be charged while remaining on the wall.
