Compact Resonance Speaker

The Yosoo Health Gear Resonance Speaker Model A is a 50 mm vibration driver that delivers 25 watts of total power through a 4 ohm load. Its round, silver enclosure measures 50 by 50 by 30 mm and weighs 268 grams. The unit connects by wire and is controlled via an application remote. It is built for multimedia sound playback and expansion across computers, laptops and portable players.

For portable audio upgrades.

Buyers who want a tiny driver that can replace a much larger traditional loudspeaker will appreciate the strong bass effect and full-range clarity. The 360 degree frequency transmission and high sound penetration suit close-range listening on desks or small surfaces. Builders who need a second channel for stereo separation, a built-in amplifier, or wireless streaming should look at something else.

4 ohm impedance at 25 watts

The single specification that decides fit is the 4 ohm, 25 watt rating, which also has an optional 8 ohm, 20 watt variant. Match your amplifier or device output to this impedance and power level to avoid damage or weak output. The 90 decibel signal-to-noise ratio and 95 dB/W sensitivity support clean output at the rated power.

Questions about this item

Will this 4 ohm, 25 W resonance speaker work with my older laptop’s audio output?

The speaker presents a 4 ohm load and draws up to 25 W, so it needs an amplifier or powered output that can drive that impedance; a standard laptop headphone jack will not provide sufficient power.

How can I verify the speaker is performing correctly after connecting it?

Play a full‑range test track and listen for clear output from 20 Hz to 20 kHz with strong bass comparable to an 8‑inch traditional driver and a signal‑to‑noise ratio around 90 dB.

What comes in the box and what must I supply myself?

The package includes only the 50 mm vibration speaker; you must provide your own amplifier or powered audio source and the connecting cable.
