My patented Planot® speaker design has no box, no tweeter, no crossover and no narrow sound. It has none of the drawbacks of old fashioned cones-in-a-box speakers. My educated guess is that 99% of all speakers in the world are wooden boxes with 2 paper cones and a crossover. At one time a necessity and always a disaster but now a solution.
The Planot speaker eliminates the need for a box and a tweeter and a crossover. Those things all add well known and extensively documented distortion to the sound. All of these were necessary requirements in the past; now they're made unnecessary by the Planot patent.
The Planot diaphragm is a rigid, long/thin rod. It is square or triangular in cross section. The rod, driven by a motor, moves back and forth around its axis. Held in place by bearings, it generates sound. Using bearings instead of traditional rubber rings, the Planot speaker motor is always perfectly aligned.
The Planot diaphragm is motor agnostic; any number of different motor technologies can power the diaphragm to create sound. Most speakers can use my dual voice coil rotary motor. For small consumer devices I suggest a rotary magnet motor where space is critical.
The Planot diaphragm can be scaled to fit smart phones, tablets, and auditoriums. A perfect fit for cars, TV's, and laptops. Just about any consumer electronics device you can think of. Long and thin fits in.
Listeners are amazed at the compactness and high fidelity of Planot speaker prototypes. They have a unique ability to decode information from recordings. Sound information that is literally lost when played over traditional speakers surrounds the listener. The Planot technology has been verified and certified by NCEE, Labs.
Speaker designers know a perfect speaker would have: minimal box diffraction (e.g., smallest box), rigid box that does not add sound, sophisticated crossovers, wide frequency response and light but rigid diaphragms. Planot eliminates the box, crossover and tweeter. Planot has wide frequency response. The diaphragm is light/ rigid; because the motor drives it at the end of its axis there isn't the diaphragm flexing of cones based speakers. Planot does not minimize but eliminates.
Planot eliminates the distortion the box adds. It has perfect phase response and wide smooth frequency response. By its nature (and by design) it produces the purest sound and is the closest analogue of the source material. It is self-evident that eliminating those things that were added to the original sound then leaves the original sound.
1) No Box. No box distortion and cost.
2) It is an omnidirectional speaker because of its shape and movement,.
3) It can be a implemented as a full range speaker.
4) It’s shape and size is unobtrusive.
5) It scales, from large to small.
6) Always centered, Planot moves on bearings, not flexible rubber hinges.
7) Planot sound does not follow the same inverse square law as cone/dome drivers, improving efficiency.
8) Unprecedented "natural" imaging.

While nature has been an excellent source of creative inspiration in the past, nature's solutions are expeditious and can't reach beyond the immediate; our curiosity must probe beyond natural models to solve humanities's problems which are quickly evolving beyond nature's narrow reach.
