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 the moment troublesome 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 sequence of normal audio system contained in the system, and that is not what Apple desires.
As a substitute, in a newly-revealed patent utility known 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 provides surprisingly few examples of what such versatile audio system may very well be used for. But it surely drills down deep into the small print of why it wants this to occur.
“Audio system with versatile elements can help ease of integration and improved conformability in quite a lot of digital units similar to head-mounted shows, laptops, good telephones, or wearable units,” says Apple. “In some examples, elements similar to magnets, diaphragms, and partitions of a housing of a speaker could 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 could be applied in quite a lot of client units to benefit from restricted packaging area and obtain improved deformability of the buyer system.”
The “restricted packing area” right here isn’t how large a cardboard field the system is shipped in, however quite the general quantity of the system itself. It would small as a headset speaker, it may be massive as in a wall, or it may very well be good in a HomePod mini.
“Shopper electronics are designed in quite a lot of styles and sizes with versatility changing into more and more necessary in an ever-connected setting,” says the patent utility. “Audio system are usually included with client electronics similar to head-mounted shows, headphones, good telephones, good watches, laptops, or different wearable units.”
“Packaging such audio system could be troublesome and is pushed by the dimensions, form, and audio capabilities of each the speaker and the digital system 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 could 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 move path for air generated throughout vibration of the diaphragm.”
This may produce audio system that wrap round a tool with a sequence of probably inflexible speaker parts, which is not the identical as having a very versatile speaker.
Element from the patent displaying how a speaker may very well be deformed right into a curve
“[However, in another example, a] versatile layer could also be a part of a show fashioned from a number of of glass, polymer, or liquid crystal,” says Apple. “The versatile layer, the transducer, or each could deform underneath 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 form of Apple-produced speaker panel to wrap round a pole on the consumer’s whim. And, the sound may range, primarily based on the form that the consumer has made with the meeting.
“A sample of vibrations produced by the transducer could also be modified primarily based 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 beforehand labored on the speaker design for the newest 24-inch iMac.
