Speaker is a form that can produce sound. In general, speakers use a room system to produce sound. The speakers that I made are flexible and coupled with the bluetooth feature to support mobility, it's just that with the battery power I installed, a minimum charge of 45 minutes can be used for approximately 2-3 days. Why do I make speakers? because it supports when homeowners do an activity, don't forget the inner melody that can be quickly brought to the world through speakers to carry out activities with the desired mood.
