Key features

• •[Audio Visualization] The ferrofluid speaker music companion brings your music to life, and its charming ferrofluid display dances and rotates in sync with the rhythm of your tunes, creating a fascinating visual experience.
• •[Material] Note: This product does not contain a speaker and will not make any sound. Ferrofluid uses nano iron powder and pure water, which is environmentally friendly and non-toxic. The product has built-in MIC and white LED backlight, and can be used without connecting any lines. It has a built-in battery and can be used continuously for 8 hours when fully charged.
• •[Use Scenario] It can be used as a music companion/sound partner for HI-FI speakers and Bluetooth speakers, a creative desktop gift toy ornament, a tension-relieving toy, a ferrofluid dancing lamp, and can also be placed on the surface of a piano as a piano metronome.
• •[Relieve Tension] Put it next to the speaker and it will dance to the rhythm of the music. Just sit back, relax, and immerse yourself in the beautiful dance. This is an immersive journey into relaxation through visual harmony.
• •[Note] The original design of our product will retain bubbles of different sizes, which are used to buffer the pressure inside the glass bottle and prevent the glass bottle from breaking. Keep the instrument upright so that the bubbles will rise to the top of the glass bottle and you cannot see the bubbles. Please do not use it at high temperatures, otherwise it will easily cause the bottle containing ferrofluid to break.
