The future of audio speakers and sound
The speakers do not seem to change much as other things in our lives, such as computers and cell phones but does not change? To find out, you can browse the latest patents granted in the important field of speakers. Foreign inventors and countries foreigners are the most common winners of patients, especially in Asia countries. This was not only the case of utility patents covering improvements to the speakers but also for design patents, which cover the artistic designs of speakers.
A quick overview of the structure from the speakers help to see where the latest innovations are being made. The mechanism of sound from the speaker is supported by a frame. The frame consists of: a basket, a soft together in a ring, and two plates bearing the load of the magnet. There are seven components of this mechanism. These elements are: the magnet, the metal core, a voice coil coil wrapped around a light weight, cone or diaphragm. The coil and cone / diaphragm is a unitary and encompassing in its position by a speaker and spider (Also known as a shock.) When current flows through the voice coil, which is driven by the electromagnetic force.
Of the 27 patents useful in the past 18 months, as many members of the voice coil, which has 8. The component with the next innovation is the cone (also called diaphragm), which has 6. The third is the spider (also called a buffer) with 4 innovations. These are followed by shopping (2), the magnet (2), packaging (1), horn (1), and surround sound (1). A patent was issued even for a new type of cover (1) that spreads the pressure waves with less interference. The prevalence of patents voice coil could be evidence that this is the critical point because it is where the electrical energy is converted into mechanical energy to push the air.
In addition to the innovations that are focused on the components, there were 10 utility patents involving a major restructuring of speaker. Examples of this include the use of bar magnets and voice coils built into the cone. In fact, most innovations involving the overall structure of the speaker were flattest speakers. A massive research and engineering effort used to create flat speakers, there is a clear trend of others in the past 18 months. This all points to one thing: The speaker of the future will be flat. At least that's what the manufacturers think. It is likely that this is based on market research that shows customers competing for flat speakers to go along with flat screen televisions.
An example of an innovation in flat speakers from a patent Sony. This design produces a speaker that can be 5 feet tall, 3 feet wide, and where the sound is generated by vibration of the engines that propel a nonporous material. No coil voice and no cone. Sony's patent includes the use of rack and pinion gear to adjust the location of the vibration in the fabric for optimum sound. All we want our flat screen televisions, and in the future, may all our flat panel speakers, too.
Independent invention is not dead. The two clear leaders in the innovation of the speakers are independent inventors and the Pioneer Company (Table 1). Combined, these two are 41% of all patents new utility in the past 18 months. After these two leaders are Sony, Matsushita, Pioneer and collaboration Co. and Honda Co., in order of number of patents. These latter companies accounted for 26% of all new utility patents. All patents were awarded to organizations for profit, except for a single patent awarded National Taiwan University.
design patents are mostly for the look of the speakers, giving the rights to the inventor of a particular type of occurrences of the speakers. Standard designs cabinet had a clear advantage over other types, with a frequency of 9 patents in 12 months. The other types of design patents are home theater cabinets, car speakers, radio communication devices acoustic remote, iPod dock, and of course, computer speakers. Other types are: coats microphone, portable speakers, subwoofer boxes, enclosures tweeter, and even speaker stands. The five types of design above represent 59% of the designs of the speakers.
Out of the patents that are just design patents, 57% were for only one speaker, 57.1%. Designs with two speakers had 26.5% of patents, patents for a much smaller number involving more than two speakers. The design with the most speakers 8. This speaker is to Moog Inc. for a radio communication device for remote sound. These military devices to deliver messages of acoustic signals potential threats in the stand-off distances.
Leading companies in the design patents were speakers from Sony in the first place, followed by Samsung, IDE Technologies, Inc. Moog, Hosiden, and Panasonic. These six companies accounted for 69% of all patents of speakers in the past 12 months. Although the two leaders are foreigners, there were also three national companies in the top six speaker design patents, which is good for American engineers to see.
One disappointing aspect of recent speakers patents for engineers in America is the predominance of foreign inventors patent more than the national inventors. The percentage of domestic utility patents for speakers was a miserable 11%. Of the 27 total patents were reviewed, 24 of them were foreigners, while only 3of they were domestic.
With regard to patents for speaker design that focus on speaker cabinets, the story is similar, with 43% of design patents speaker will be national inventors. Although American inventors do not take into account for the majority of patents in the design of the speakers, they are obviously interested in speaker design in speakerphone function.
Electromagnetic He now has largely the same structure since it was patented in 1875 by Alexander Graham Bell. The confidence he could not have been the target of radical technical inventions for some time, but the most recent patents demonstrate that radical improvements in the design and performance may be in our future.

How I can leave my speakers make a high pitched noise while playing music?
I realize that certain songs I play have a strange effect on my speakers. While playing music, my speakers emit a high pitched hum, usually in the lower notes high. Other songs that I have, going to the same notes and beyond, do not have that effect on my speakers. Is it because the mp3 is bad? Or is it because of my speakers? I'd appreciate any help with this.
u should lower levels that can help and make sure that your iTunes songs that guarantees good sound quality ........... I hope that helped
