As the material for conventional speaker cones, various materials have been used, such as natural wood pulp, synthetic pulp comprised of synthetic fibers or plastic, natural fibers, synthetic fibers, carbon fibers, glass fibers, or films of plastic. Speaker cones are manufactured utilizing the characteristics of these materials. Loudspeaker cones can be manufactured from various materials depending on driver implementaion, desired frequency response for each driver. Although the speaker cone is technically the cone shaped part, a cone is many times also referred to as the cone/surround assembly to include the outer suspension called the surround. Quality midrange and bass drivers are usually made from paper, paper composites and laminates, or plastic materials such as polypropylene or mineral/fiber filled polypropylene. Such materials have very high strength/weight ratios (paper being even higher than metals) and tend to be relatively immune from flexing during large excursions. This allows the driver to react quickly during transitions in music and minimizes acoustical output distortion. If properly designed in terms of mass, stiffness, and damping, paper woofer/midrange cones can outperform many exotic drivers made from fancier more expensive materials



A speaker spider which has a central opening defining an inner rim, a periphery outer rim, and a spring effect portion provided at a portion located between said inner rim and said outer rim to enable said inner rim to be moved axially up and down with respect to said outer rim when a driving force is applied to said inner rim and be retained to an original position after said driving force is released at least a pair of lead wires each having a length longer than a distance between said inner rim and said outer rim of said speaker spider, wherein

each of said lead wires has an inner end portion, an outer end portion and an attachment portion extended between said inner and outer end portions, wherein said two attachment portions of said two lead wires are spaced extended between said inner rim to said outer rim of said speaker spider while said inner end portion and said outer end portion of each of said lead wires are outwardly extended from said inner rim and said outer rim

of said speaker spider respectively, and means for attaching said attachment portions of said lead wires on one side surface of said speaker spider so as to ensure said attachment portions of said lead wires being spaced extended between said inner rim and said outer rim of said speaker spider and to integrate with said speaker spider to move simultaneously; wherein said attachment means comprises at least a piece of attachment member, made of a sheet like material, having a length at least equal to a width of said attachment portion of said speaker spider and a width larger than a spaced interval between said pair of lead wires to be attached on said speaker spider, wherein an adhesive layer is applied between said attachment member and said side surface of said speaker spider so as to adhere said two lead wires on said side surface of

said speaker spider. Company works on paper cones, speaker component, Electronic components.

We are in the business of wining trust, offering commitment and creating long-term relationship. We conclude, with fond hope of getting an early response to vouch our worth. He resulting fabric increases the speaker cone's rigidity and strength while keeping weight low. Speaker engineers are extremely passionate in their quest to build speakers that reproduce the highest sound quality possible. They are constantly looking at different materials that can be used to make a more efficient speaker with a stronger more rigid cone. They are constantly looking at different materials that can be used to make a more efficient speaker with a stronger more rigid cone. The new cones are matched with an ultra light weight soft dome tweeters in both the coaxial and component versions. The large soft dome tweeters, made of high quality laminated polyester, use a finite element method .In the coaxial version, the tweeter is placed in a waveguide chamber to control and direct the sound to the listener's ears.

Standard speakers use cones made of paper or some other material (many use different fabric, rubber, polymer, or metal cone construction) combined with a magnet to move air and produce sound. Metal cones will generally only be found on tweeters , which are small speakers, typically no more than 1" or so in diameter. The magnets move the cones, and the cones push air to create the sound. Many speakers are two-way or three-way .This refers to the number of speakers in the cabinet and how the input signal is divided among them. A two-way speaker will have at least two speakers in the cabinet, along with crossover circuits to divide the incoming signal so that one speaker handles the higher frequency sound while the other speaker handles the lower frequency. A three-way speaker is similar, but divides the input into low frequency , mid-band frequency , and high frequency These allow the designer to design the speakers and enclosure to provide maximum performance in each region
