By installing the wireless speakers and RX boxes in different rooms and building a stable wireless network using the Wi-Fi, each of these wireless speakers enables users to listen to the audio sound from one or multiple sources so that users can have a multi-room wireless speaker system. The design of the wireless speakers stresses the product’s functionality by using wire mesh inside the metallic frame. Also, by using angular shapes in the external design, we tried to visualize the image of the sound waves spreading in the multi-directions inside the room. Lastly, at the lower part of the product, some space is left to make the product look simple and light. In conclusion, the design of the wireless speakers stresses the product’s functionality and distinctiveness.
