Apple is researching methods to make audio system that embrace hinges, can bend round corners, cram give large sound into small enclosures which are at present tough to handle.
The present HomePod is cylindrical and at current the HomePod mini is nearer to a sphere. However actually these shapes are simply the housings that go round a collection of normal audio system contained in the machine, and that is not what Apple needs.
As an alternative, in a newly-revealed patent utility referred to as “Versatile Audio system,” Apple describes audio audio system that may be bent, and are literally cylinders, spheres, or different non-flat surfaces.
In a patent utility that runs for simply over 10,000 phrases, Apple offers surprisingly few examples of what such versatile audio system may very well be used for. However it drills down deep into the main points of why it wants this to occur.
“Audio system with versatile elements can assist ease of integration and improved conformability in quite a lot of digital units comparable to head-mounted shows, laptops, good telephones, or wearable units,” says Apple. “In some examples, elements comparable to magnets, diaphragms, and partitions of a housing of a speaker will be versatile and operable in varied folded, bent, or curved configurations.”
“In different examples, partitions of a speaker can embrace sections coupled by hinges that enable flexibility or deformation of parts of the speaker,” it continues. “The versatile audio system described herein will be carried out in quite a lot of client units to reap the benefits of restricted packaging area and obtain improved deformability of the buyer machine.”
The “restricted packing area” right here is just not how large a cardboard field the machine is shipped in, however slightly the general quantity of the machine itself. It would small as a headset speaker, it is perhaps giant as in a wall, or it may very well be excellent in a HomePod mini.
“Shopper electronics are designed in quite a lot of styles and sizes with versatility turning into more and more vital in an ever-connected setting,” says the patent utility. “Audio system are sometimes included with client electronics comparable to head-mounted shows, headphones, good telephones, good watches, laptops, or different wearable units.”
“Packaging such audio system will be tough and is pushed by the scale, form, and audio capabilities of each the speaker and the digital machine inside which the speaker is built-in,” it continues.
In each case, a speaker has to incorporate “a housing having partitions that outline a cavity, an electromagnet disposed within the cavity,” says Apple, which is “configured to selectively generate a primary magnetic discipline, a everlasting magnet disposed within the cavity and configured to generate a second magnetic discipline, and a diaphragm configured to vibrate throughout interplay of the primary and second magnetic fields to provide sound waves.”
That is an outline of nearly each speaker ever made, however Apple can be now suggesting that a technique elevated flexibility may come is by way of hinges and ribs.
“The speaker might embrace ribs disposed at spaced places within the again quantity,” it says, “[with] every rib extending from one wall towards one other wall in an alternating method, and the ribs forming a circuitous movement path for air generated throughout vibration of the diaphragm.”
This is able to produce audio system that wrap round a tool with a collection of probably inflexible speaker parts, which is not the identical as having a very versatile speaker.

“[However, in another example, a] versatile layer could also be a part of a show shaped from a number of of glass, polymer, or liquid crystal,” says Apple. “The versatile layer, the transducer, or each might deform below bending stress such that the speaker is configured to provide the sound waves each in an undeformed state and in a deformed state.”
That is what would enable some type of Apple-produced speaker panel to wrap round a pole on the person’s whim. And, the sound may range, based mostly on the form that the person has made with the meeting.
“A sample of vibrations produced by the transducer could also be modified based mostly on the curvature detected with the sensor,” it concludes.
This patent utility is credited to Chanjuan Feng and the prolific Paul X. Wang. Each of them previously worked on the speaker design for the newest 24-inch iMac.
