Product concept: the product is a wireless audio device, which allows users to easily and conveniently enjoy a wide selection of music at home through mobile apps, as listening to music online has become the main trend. Design concept: as soon as people press the small triangle-shaped play button, the space around them gets filled with music and this changes the space, its atmosphere and their feeling. The starting point of these changes is the triangle-shaped play icon. Therefore, the triangle means the start of change and a new starting point. That is why we designed this new and fabulous triangle shaped audio device.
