If you love the sound and music, then you know that the quality of the speakers of the major factors that determine the quality of sound. Speakers not seem to have as much as other things in our lives, how to change computers and mobile phones, but they are fixed? To find out, you can browse the latest patents in the important area of the speakers sound excellent. Foreigners and foreign inventors are the most frequent winners of patients, especially from Asian countries. Thiswas not only for utility patents covering improvements of speakers, but also for the design which is to cover the artistic designs of speakers.
A brief overview of the structure speakerphone helps you see where the latest innovations are made. The mechanism of sound generation of the speaker is held in place by a frame. The panel is composed of a basket, a soft seal and two donut-shaped plates that carry the load of the magnet. There are seven components of this mechanism. ThisElements are: the magnet, the metal core, a coil wound around a reel light, the cone or diaphragm. The coil / diaphragm is a common agreement and held in place surrounded by a speaker and a spider (also known as a shock absorber). Flow of current through the coil is pushed us with the electromagnetic force.
Of the 27 samples used in the past 18 months, the largest number in the coil, which belong to '8 The component with the nextInnovation is the cone (also called membrane), which is the sixth The third is the spider (also known as a shock absorber) with 4 innovation. Following this, the basket (2), Magnet (2), seal (1), horn (1) and surround (1). A patent was also for a new type of cap (1), the pressure waves spread out with less interference. The voice coil domain of patents could only prove that this is the critical point, because this is where the electricity is converted into mechanical energyfor air pressure.
In addition to innovation, which focuses on components, there were 10 utility models, which involved restructuring of the speaker. Examples include the use of bar magnet or coil incorporated into the cone. In fact, most of the innovations for the global structure of speaker flat speaker. A massive research and engineering to create flat speakers issued a clear different trend in the last 18 months. All this indicatesone: the speaker of the future will be flat. At least that's what the producers think. This is probably due to market research, customers are racing to get to flat speakers, with their flat-screen TV programs are based.
An example of innovation in flat speaker comes from a patent by Sony. This project provides a speaker, 5 meters high, 3 feet wide, and where the sound of vibrating motors that a non-porous material is generated can go. There is no reel cone.The patent covers the use of Sony rack and pinion, to adjust the position of the vibrations to the fabric for optimal sound. We all want our flat screen televisions, and in the future, we all want our speakers even flat screen.
Freelance is not to invent died. The two speakers are the clear leader in innovation and independent inventors Pioneer Company (Table 1). Together, these two up to 41% of all new utility patents in the last 18 months. Following these two leaders are Sony,Matsushita, Pioneer and Co. Co. Co. and Honda, in order of number of patents. These two companies represent 26% of all new utility models. All patents were awarded to nonprofit organizations with the exception of a lone patent from National Taiwan University.
Design patents are primarily looks for speakers so that the rights of the inventor of a particular type of speaker presentations. Standard design speakers had a clear advantage over other types with aFrequency of 9 patents in the last 12 months. Other types of designs are for home theater cabinets, speakers, remote from the acoustic devices, docking stations for iPods and computer speakers, of course. Other types are: microphone shields, portable speakers, subwoofers, tweeters and also accommodation speaker stand. The first five types above represent 59% of the speakers listed styles.
Out of the patents, the patents had been just design, only 57% forone speaker only, 57.1%. Designs with two speakers were 26.5% of patents, with far fewer patents, which involved more than two speakers. The design with the largest number of speakers had 8 The speaker comes from Moog Inc. for an audio device at a distance. These military devices for providing acoustic signals of potential threats in stand-off distances.
The leader in the design of loudspeakers Sony patents in the top slot, followed by Samsung SDI Technologies Inc.Moog Inc., Hosiden and Panasonic. These six companies accounted for 69% of all patents speakers over the past 12 months. Although the two leaders are foreigners, there were three national companies in the first six for speaker design, which is nice for American engineers to be seen.
A discouraging aspect of recent U.S. patents for loudspeaker engineers is the domain of patents by foreign inventors inventors home. The share of pension benefits in private homesPatents speaker was a meager 11%. Of a total of 27 patents that have been checked 24 of them were foreigners, while only 3of were home.
In terms of design patents microphone, which is situated on speakers, similar to the story, go with 43% of speaker design to domestic inventors. Although it is not the American inventor for most of the patents in speaker design, it is clear that they are more interested in the design of the speakers as speakerFunction.
The speaker is now electromagnetic largely the same structure, since it was patented in 1875 by Alexander Graham Bell. The spokesman for the faithful can not be the target of radical technological inventions for some time, but the most recent patents show that the radical design and performance can be improved in our future.
