I have designed a Bluetooth speaker based on the Makita brand. The user wants something practical that is of high quality. In order not to complicate the Bluetooth speaker, the functions and therefore the buttons are kept to a minimum. To make the speaker easy to use, it is the right size to be carried with one hand. It also has a device that allows the user to mount the speaker in the environment so that it is not in the way when working.
To turn it on and off, press the center button once. To connect to another device, press and hold the center button for 3 seconds. You will then hear a tone to let the user know that the speaker is ready to be paired. Use the minus and plus buttons to decrease and increase the volume respectively. However, if you hold them down for 3 seconds, you can also switch to the next song or play the previous one.
