Portable Bluetooth Speaker design.

IMAGE: The two brothers Jayden and Daniel Bryant (left to right) from Huntly College (NZ). They completed the kit set bluetooth speaker in Feb 2020. 

'Two secondary school students assembled the bluetooth speaker (kit set) all by themselves today (25 Feb 2020). No guidance from the teacher. The two brothers, a 13-year old and 14-year-old boy, worked with only the instructions at their disposal. Within 45 minutes they were able to fully pre-assemble the bluetooth speaker (no glue to the box). This pre-assembly went very well. Once they had completed the speaker successfully, they had a sparkle in their eyes and said: "Sir, can we take it home we want to show it to our mum?" They further commented: "It really sounds good; the bass is excellent for such a small speaker!  The two proud brothers left with the bluetooth speaker carefully wrapped in their school bag. Success!'

In this video: 'Stefan shows us how to make the battery box from our SharperThinker kit ‘DIY Bluetooth Speaker’. You will need the kit, scissors, screwdriver and PVA glue. You can buy our kit online at: www.sharperthinker.co.nz. Our kits are wooden and as eco-friendly as possible. We design and make them to high quality standards.'  CREDIT:Text taken from the YouTube video.

DESIGN BRIEF (after the bluetooth kit set was completed by students).

Situation: Now that you have successfully assembled the bluetooth speaker from Sharper Thinker, explore different shapes and forms for a new speaker box. The focus is on the process of new ideas and concepts. Once you have explored the new ideas, choose one and develop it (modify, 'make it better,' make changes).

Brief: Design a portable bluetooth speaker (NCEA Level 1, 2 and 3). 

* RANGE: For 16-year-old students to 18-year-old students (NCEALEVEL 1, 2 & 3)


Consider all the electronic components of the kit set. Think about possible shapes and forms that could contain all the different electronic components (batteries, amplifier, bluetooth unit, inputs and outputs).
