The loudspeaker manufacturer, Noboru Denki, designed a high-quality speaker that does not require any power source. The Sound Loudspeaker NMP-001 is a non-powered speaker that easily connects to any smartphone and produces an unmatched sound.
The speaker is shaped like a horn and uses the reverberation of the three-layered shape to create a strong sound. As the sound travels through the tube, reflex, and horn - a high-quality tone is produced. Once connected to a smartphone, the speaker can play music from a user's music library or through a streaming radio.
Made with aluminum, this device is ideal for spaces where the power supply is remote. This highly thought-out design has been tested in an environment with no ambient noise or reverberation to ensure a quality sound.
