The DED-60TX is a musical instrument that combines a Bluetooth speaker with a pad. Following the idea of enabling “mobile and easy learning”, it includes a drum pad, two 10-W stereo speakers, two drumsticks and bass drums in one device, and it can be used as a music player and editor. Its understated body in the shape of a triangular prism serves for stability during utilisation. The flexible percussion pad is integrated into the body. The DED-60TX is equipped with a lithium battery and supports 5V USB power supply.
