# Non-Powered Horn Speaker Noboru Denki's New High-End Speaker Does Not Require a Power Source By Francesca Mercurio | Published 2021-09-17 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/noboru-denki References: [designboom](https://www.designboom.com/design/noboru-denki-no-power-loudspeaker-nmp-001-09-16-2021/) The loudspeaker manufacturer, Noboru Denki, designed a [high-quality speaker](https://www.trendhunter.com/trends/hoan-desktop) that does not require any power source. The Sound Loudspeaker NMP-001 is a [non-powered speaker](https://www.trendhunter.com/trends/leapsonic-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](https://www.trendhunter.com/trends/gadol-vibration-speaker) 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.
