Miniature Loudspeaker

Introduction

CQRobot has carefully configured this passive miniature loudspeaker for makers and electronics enthusiasts, Compared with the previous generation, the volume level has been greatly improved. There are 3 different models of speakers: 3 watts 4 ohms, 3 watts 8 ohms and 5 watts 8 ohms; 2 types of JST PH2.0 and 2.54mm DuPont interfaces. long strip size, with mounting screw holes, suitable for all kinds of small DIY electronic projects, the sound is clear and pleasant without distortion.
