hi all
attached is a new type of speaker design
walk around so can hang or go on a stand
stereo
and no moving coil no magnet and no cone
can be further split for quadro etc
and very high powered
needs a tweak or two to the design
but the basics is there
the iron rings are bonded to the hemespherical wood sound emitter

Always good to see new concepts. The Rice-Kellogg cone driver is as close to over-bloated obsolescence as the internal combustion engine in cars.
Is it a Magnepan with mag-lev suspension?*
Looks like there is a soft "surround" to support the diaphragm when the suspension power is off and to address front-to-back out of phase cancellation.

By function a cone is a large area that moves air in a speaker. This one has a hemispheric radiator and so is an equivalent 'cone'. There are several coils. One shown behind the apex of the hemisphere appears to drive it and isn't that a 'moving coil' ? So the description appears to be misleading ?
A speaker that really fits most of the description would be a plasma speaker ( usually tweeter!).

hi
there is no moving coils
the reflex dampen system isnt adjusted other than at power on
the DC levitation can be modulated
the hemespheres can be textured and the higher frequencies split off to drive the hemespere centers drive coil set
the drive coils are mounted on disks
the center of the hemesperes is a dual coil
right and left
there is no cone infact the exact opposite
the drive system can be set up to accept line input
and just one fet per coil on each ring
the fixed point is enough to hold the hemespheres fully
and the speaker will perform quite well
but with active setup
then it will sound much louder and clearer im sure
as i say it will need tweaks and design thinking
but i cant see anything like this anywhere anything similar
and the SST split sphere tech has other uses
forinstance it can be used as a very sensitive directional mic
or as a transducer if made smaller or perhaps made of quartz
self contained for cleaning pipes

no just at the drawing stage and iron out problems before having to make another one
saves a bit of time
ive done some spacial simulations seems to give a good projection of sound
the texture of rings i think
the problem i have is model software is rubbish at this kind of thing
speaker design software all runs around cones and woden boxes
if anyone has an idea of a good simulation tool
as for the electronics this part is easy and very easy to build
the iron ring can be replaced with iron slugs per coil step coupling core
so this will reduce the weight and aid in resosnace..
i see this place and im thinking this is a good place to fire it at..

I don't understand how sound is produced without any moving part. Sound requires air as a medium , for the ear to hear. Something needs to move that. If there is vibration of the hemisphere then that is the moving medium, an equivalent cone ! In a plasma speaker even that does not exist but it works in a different way altogether.
If the coils do not move what do they do ? Generate a magnetic field which does what ?
Can't figure out how this works !

on the first look, it reminds a MBL omnidirectional sphere like speakers
on closer look, as it states, there are no moving coils, so no MBL type coil in the magnet gap moving up and down squeezing the sphere...
on even closer look at the drawing provided, moving part is iron core inside the coil pushing to some spherical membrane from various materials
few issues I see...I do not know how the membrane will pulsate, as I do not know its rigidity, if it is very soft, it will be like finger pushing on balloon, nothing happens and no sound, if it is rigid, then two sides will be fighting each other, and no sound
the iron which moves is in "big small" drive coil, the name itself is oxymoron, but never mind
there are reflex balance coils, as the diagram shows, they somehow move back and forth, indicated by arrows, but description of this contraption has no moving coils, so a contradiction
not sure of the function reflex balance coils
anyway I do not know about this simeon w...you got a lot of explaining to do
I do not mean to criticize, I am scientist and it is imperative for me to understand stuff

its quite hard i suppose to get your head around the hemisphere
they produce the sound !!!! and are made of wood metal plastic etc or multiple materials
composite carbon etc
for instance
if i take a 50CM hollow sphere cut it in half
and bond the iron slugs or a ring to the hemisphere edge
this is the sound transmittion surface from the coils EMF coupling to the iron
you say use a magnet the plan is not too use a magnet or magnetic ring
then drill a hole in the center of the hemisphere
and place another set of slugs
behind the slugs or rings is a ring of coils
so the sound is transmitted By magnetics EMF to the hemisphere for radiation
of the sound
you can add rings on the outside of the hemisphere to give peeks at different frequencies
and flatten the response
i find most people dont understand how it works
not through lack of knowlage its just the crap cone fixed mag speakers have been around for over about 150year its fixed solid in their minds
so infact you dont even need a conventianal amplifier with its zobial network
and coupling capacitors and large transformers etc
this design will accept line level and a say 12v DC supply
as you can just mount 1 X fet per coil section of the rings of coils
if you think of a syncro motor drive coil
then use the unit as one coil
the design will need tweaked up and perhaps slits cut in the hemispheres
or material change
but there is no issues with using more coil rings
the power coupling is huge and this design will handle a kilowatt easy...
no more small wind moving coils
or large heavy fixed magnets
however i can see how it works and that to me is all that matters
ps i already know it works i built a small one from an hamster ball
and the sound appears so it does couple and work
just needs scalled and tweaked
afterall the speaker was made from carbon dust and didnt have a fixed magent
but still used a dodge cone and a small wind low power coil
as i say im finding it hard to model and im well used to simulation
best ive come up with is to use a heater simulation model
and treat the sound like IR

the reflex balance coils are only set when you power on the unit
they dont move about they are for a fixed tension
and are part of a high power setup
a small home SST prob wont need them
just a fixed point and some reflex springs could be enough
im sorry you just cant see how it works
but its very very easy and as a scientist you should be able to break it down
to audio in and how the audio comes out of the hemispheres
scalling up the SST you can use it split a bit as 3D radar 3D sonar
and as a 3D transducer .. many uses for SST
3D antenna {high gain } not a dipole a radiating sphere choose plane scan
also 5 point audio
you can use one hemesphere as a sub woofer then 4 channels to the SST
once you click to it im sure youll share the idea
sometimes science will tell you nothing becaouse your missing a few connections
to invisage the full idea

what ive done all my life is RF radio and electronics design
sometime software {vsmlibs}
and sometimes hardware
but SST is a brand new tech
i agree its hard to invisage
but it does work
and the actual power transfer is 10X a speaker
so 1 watt on a SST will give stereo and fill a room
directional speakers are exactly that
old tech and redundant
however progressed they are they pale into non reality
against the power and quality of an sst when fully developed
conventional speakers are 92% inefficient
and are directional
and are basicaly too load in some parts of the band
with sst you can simply hang it from the center of the room
and it auto tunes {progressed version with a year max of development }
even add a light bulb to it
so far ive just used some old coils from a video modded a bit
and iron rings i had to make with a saw and took hours
but it produced sound and quite load .. and stereo
its a progession of making
first plan the design then see whats wrong with it thats easily fixed
then build one
i dont have the cash for too many protos and dont have the time during the summer
so just now i have plenty of spare time
so next ill make a wood version
if anyone feels like making one i can help
the optimal size could be 1M dia hemisphere of something like
a hard wood with optimal softwood areas
the hard woods give a low frequency the soft the higher ones
im not so good at drawing stuff so youll need to get by
with the drawing i did
their is no patent for this design as i dont need one
copyright is plenty as it reuses already patented tech,,,

i still dont get it. whats the slug where is the coil ,is the ring the coil ? i am completly clueless in what i see here.
Whats the flap on top of the sphere ? coil ? or a metal ring ? could you explain the basics of operation because i notice you have an idea and are pretty stoked by it, and i tend to start rambling when i am. looks like you got this to and now i have no clue what you are talking about. i miss a link somewhere.

i feel the trick is to use non polerised iron or some laminated slugs
to avoid eddies and magnetising the slugs or rings
some degouse can also be added
perhaps using aluminium coil wire and
some iron core again perhaps laminated
the coils and rigs need to 'float' both for emf and drive force
to gain max volume the levitation system is a good addition
but not needed in a home or studio situation
headphones again are easy
and mics;;; well super sensative
from the hamster ball i could record sound 30 meters away
voice audio
and still get 30DB mic level

ok let me explain further
the hemespheres outer circle you mount the slugs or ring too
the slugs sit above the coils they dont move!!! just the iron rings or slugs move
i say slugs becouse it will help to use a non fixed ring as it will reduce the volume
each coil in its ring has a core
and the core has windings driven by a fet
so 20 coils and cores and 20 slugs
i used 4 on the hamster ball outer and 2 inner {apex} drivers
and a iron rings
then i came up with i need to use slugs
so the slug will vibrate with EMF from the coil it sits above
iron is best but any ferros metal will do....
two sets of driven coils one at the apex of the hemisphere one at its base
the coils are individual as a set but all driven at once per side {hemesphere } as a ring of coils
like a syncro motor has....
its a no brainer ...?? not sure why your having trouble
think about a hollow sphere
then cut it in half
mount rings of iron or individual driven slugs to each of the spheres cuts
then coils drive the ring !!!
and make the spherical unit bounce up and down and re radiate sound
if you cant see how it works there is something wrong with humanity...for sure
so simple ....
you can scratch your head
go back too the start and re read

why would you ad a heavy metal ring to the edge of the hemisphere. and not a light coil ?
you use it as an solonoide ?/electromagnet core into a coil ? if so is the core not a bit heavy to modulate ?
i will be going back to the start and reread, saying it is sooo easy wont help much i think. i dont see replies here where poeple say aaah yeah sure good idea thats easy.
last but not least since you made one already do you have a picture ? it might help understanding it. i love new ideas dont get me wrong!
Oh you say coils. are there more then one coils at the edge of where you cut the sphere ? or just one.
