Gadgets and just Gadgets

JVC launched a “revolutionary” speaker. It looks like a sphere with angles.
It is supposed that this gadget it is able to give birth of a sound more natural.

JVC Pulsating Sphere Speaker

I said this JVC Pulsating Sphere Speaker is “revolutionary” because JVC’s first sphere speaker was from 1967.

Main Features

1. Natural, ideal sound-field reproduction from 12-sided ball-shaped compact speaker
With a diameter of 10 cm, about 4″, the speaker is divided into twelve 5-sided sections. Excluding the bottom, each are driven dynamically by 11 drivers, realizing high-power for the speaker’s compact size. Sound coverage is uniform in every direction in range up to 10 kHz, varying by less than +/-1 dB. This results in an unprecedented natural sound field.

2. Linked diaphragms permit entire speaker surface to act as emitter
The JVC developed linked diaphragm construction utilizes the entire surface of the speaker as an emitter, with eleven 5-sided segments linked only at their edges. This eliminates effects from a frame or cabinet, and results in a clear sound without distortion.

3. Wide, flat frequency range thanks to Weibull-curve diaphragm
The diaphragms have a ‘Weibull curve’ shape optimized using computer analysis. Plastic reinforced with stiffening fibers, flat frequency characteristics and low distortion result in a clear presence without hotspots. This also results in a wide frequency range.

4. Double neodymium magnets give high magnetic-flux density of one Tesla
With two high energy density neodymium magnets, the equal-diameter speakers produce a high magnetic-flux density of one tesla. Thus, thanks to the magnetically held and driven linked-together diaphragms, the speakers reproduce clear sound across a wide range.

5. Orthogonal double-suspension construction stably supports edge-linked diaphragms
The new two layer right-angled orthogonal suspension has good hardness but avoids fixed resonances, leading to highly accurate drives. Using this technology, JVC succeeded in driving the linked diaphragm precisely, as if it were breathing.
