Abstract

Music, one of the methods for people to enjoy and relax on many occasions. People often use music as a form of therapy. Different songs can be utilised to help those who are struggling with emotional, social, spiritual, and cognitive issues. Nowadays, many people play music through Bluetooth speakers / headphones due to its ease of use, convenience and many more features. However, many Bluetooth speakers on the market lack multi-function features and are primarily designed for music playback. This situation has made the objective for this project, develop a portable Bluetooth speaker with a few extra add-on features to attract users’ interest. This portable Bluetooth speaker is equipped with digital indicators, RF remote control, signalresponding LEDs, flash light and solar panel charging. This project makes use of multiple prebuilt PCBs and components for the circuit and creates a 3D- printed enclosure using 3D design and printing software. The project was categorized into three stages to complete, which were circuit design, circuit testing, and enclosure design. A Wide range of data and results were obtained to determine the performance of the speaker, and various functions of the speaker were proved to be working as expected
