Design of Unconventional Speakers

February 23rd, 2009

Design of Unconventional Speakers

Horn loudspeaker:

This is the oldest type of speaker used and was first incorporated with cylinder recording players. They used a waveguide to increase the directivity of the speaker and propagate the high pressure at one end of the speaker to a larger area at the other end of the speaker; this increases the speaker sensitivity. The design of the speaker like the throat size, mouth diameter and the horn length must be carefully chosen to get maximum frequency response.

Piezoelectric speakers:

These speakers are usually incorporated in the watches as beepers and also as tweeters in cheap systems like radio and computer speakers. Some of the advantages the Piezoelectric speakers have over conventional horn loudspeaker are: they can withstand high frequencies, and their electrical property permits them to work without crossover. Some of the disadvantages of Piezoelectric speakers are: there is a possibility of amplifiers to oscillate and damage itself when capacitive loads like Piezoelectric speakers are present, and their frequency response is much less when compared to other speakers.

Electrostatic speakers:

These speakers are driven by high voltage electric field. It consists of a thin, charged membrane and the electric field drives the membrane. They have few disadvantages like low efficiency, and it attracts dust particles as its membrane holds static charges.

Ribbon and Planar Magnetic speakers:

The ribbon magnetic speaker consists of a thin ribbon made of metal which is suspended in a magnetic field. When an electrical signal is made to pass through the ribbon the ribbon moves to make sound. They have the advantage of giving good frequency response for high frequencies, but they are extremely fragile and they are costly to construct as it requires a very powerful magnet.

Planar magnetic speakers are speakers made up of a coil and a stretchy membrane. When current is passed through the coil the magnetic field of the coil interacts with the field of the magnets present around the membrane which will vibrate the membrane.

RING DESIGNS

February 23rd, 2009

RING DESIGNS

A ring is of many types, sizes, shapes and is used for different purposes. It may be for an engagement, wedding, as a gift to a loved one, or simply a means of pampering oneself. But in all these uses, there is one common factor that one always looks for, and that is the design of the ring. The choice of design and style may differ from person to person, but is very important choice.

Finding a perfect selection is not just about the setting or the cost of the ring, it also depends on the wearers’ personality and the individual style statement. The reference of a traditional design or modern one, whether it should be in gold or platinum, whether it should be an intricate design or a simple band, all this counts while choosing a ring design.

The most common and widely preferred categories of rings are solitaires (simple rings with a single gemstone in the centre), ethnic rings (designs in tribute to cultures), contemporary rings (sleek and modern rings made by famed jewellers), custom-made (a personalized ring designed by oneself), vintage (antique designs) and art deco rings (flashy and colour-filled styles with bold textures). The expensive rings out of these are the vintage and contemporary rings.

The design of a ring also takes into consideration the stone setting, metal setting, textures, weight and colours. The metal setting is the choice of metal to hold the precious stones to the band. This can be yellow-gold, white-gold, platinum, titanium, or multi-tone metals. The most liked stone choice that fits into any ring design is the colourless diamonds, though pearls, sapphires and rubies are also popular choices. The centre-stone shape is another important feature of the ring design. The widely used shapes are the square princess cut, a triangle trillium and the famed marquise cut.

Selecting the perfect ring design is based upon how one merges their preferences, the choices available and the range of budgetary and expensive rings.

WEDDING RINGS

February 23rd, 2009

WEDDING RINGS

A wedding ring is typically a metal band set with diamonds and other precious stones. It symbolises matrimony and commitment to one’s spouse. It is worn in some countries on the left ring finger and in others on the right ring finger. Wedding rings are made mainly out of a yellow gold-alloy, strengthened with tin, bismuth or copper. White gold and platinum are also components that are used for a wedding ring, and more recently titanium has also become popular.

People most often choose a simple gold-alloy band as their wedding ring as it is easy to keep clean, and lasts long. These rings are usually made in pairs, a narrow one for the wife and a broader one for the husband. In some customs, the wife wears both the engagement and the wedding rings together on the ring finger. Sometimes, the spouse’s name or the wedding date is engraved on the rings for an extra-special touch, bringing about a sentimental value to the ring.

There are many designs and styles of wedding rings that are widely used today. Some of the more exclusive fashions are two-tone interlocking rings, made of one strand of gold and one strand of platinum or titanium; a simple gold band with onyx mixtures running around it; a scroll kind of wedding band encrusted with diamonds; and a platinum band sporting round, pear-shaped or marquise coloured stones. The more work that goes into the designing of the ring, the more they become expensive rings.

Wedding rings are generally not as costly as the expensive rings given at engagements. They are preferred by most people to be simple and chic. The simple gold-band rings would cost you anywhere from £59 to £195. If one goes for a more stylish platinum or titanium ring with diamonds or other stones encrusted, they would cost about £295 to £400.

GOLD RINGS

A Gold Ring is undoubtedly the most popular among all kinds for any occasion. It is sleek, looks classy, and lasts very long. Also, Gold can be made into any shape and style, and size and can be worn anytime anywhere, with any outfit. It is the perfect gift for any occasion and symbolises a feeling of love.

There can be 3 types of gold rings – White gold, Rose gold, and the more common Yellow Gold. These rings are weighed in karats, which may be 9k, 14k, 18k, or 24k. The best gold quality is incurred with the 18k gold as it has unique characteristics, ideal for a ring. Although a gold ring may lose its brilliant shine after long years of use, it can always be polished by any jeweller to bring back its look.

The best gemstone to enhance a gold rings beauty is the diamond. It is the undisputed companion of a gold ring. This combination reflects a sense of power and a lasting commitment, along with a timeless commitment that appeals to every person. A diamond and gold ring can also be chosen in a diverse range of styles and designs. They are also extremely durable, withstanding any kind of usage. However, adding a diamond to the gold band would, needless to say, make it an expensive ring.

The most decisive factor while purchasing a gold ring is its size. However, other factors like style, cost and its durability must also be looked into. Also, the fact that gold can be mixed with other metal alloys is a very important consideration. Mixing gold with alloy makes it easier to shape into any design one wishes. White Gold is formed by alloying gold with platinum or nickel, and rose gold is obtained with a combination of gold and copper. The most popular among these however, is the yellow plain gold, which also makes for the most expensive rings.

Eternity rings

ETERNITY RINGS

Eternity rings symbolises forever love. There is no specific occasion when the ring is given to a loved one. It may be for an anniversary, the birth of a child, or just a means of proclaiming your love for someone. In short, it means just what its name suggests, an eternal promise of love towards a loved one.

The most popular choice of gemstones for an eternity ring is undoubtedly diamonds. Even though rubies, emeralds or sapphires are also used, diamonds to the chart of any list for an eternity ring. A diamond gives a sentimental, sophisticated and refined feeling to the purpose of the ring. The gemstones’ shape is equally important to the choice of the stone itself. A square or rhombus shape is preferred over a rounded structure as they are easier to cut and fit together.

The eternity rings come in different styles as well – the Full and Half eternity rings. The full eternity ring is one that has stones fitted all around the ring’s surface. The stones for this type need to be small enough to be fitted along the entire ring; else it gets unfeasible to wear. Also, they have to be custom-made as they would depend on the size and design of the individual. Half eternity rings are ones that have stones placed only on the face of the ring. This is better preferred as they are easier to make, to wear and all the stones are visible. Needless to say, the Full category is the more expensive rings.

Eternity rings are normally worn along with the wedding ring on the ring finger. They can also be worn in place of the wedding ring or along with the engagement ring alone or all three, i.e. the wedding ring, engagement ring and eternity ring, may be worn together on the same finger. All in all, regardless of the rings style, cost or reason, it is the emotional sentiment that carries the maximum weight.

Your guide to car leasing

February 23rd, 2009

Do you ever feel like you know just enough about car leasing to be dangerous? Let’s see if we can fill in some of the gaps with the latest info from car leasing experts. Car leasing has gained popularity because for some, it is a far better option than buying a car. Car leasing is paying for the cost of the vehicle that you plan to lease with the value by which it depreciates. A car manufacturing company which introduces new models every year would have a brand which depreciates more than another which only brings out new car models every couple of years. Choose the brand which depreciates less. If you lease a car, your lease contract may stipulate that the lease will last from two to four years. There are some things to remember when leasing a car. First, you need to have good credit. If you have a bad credit history or a low credit score, you will be quoted a higher monthly lease. Remember that your objective in leasing a car is to save some money when you compare it with buying a car. It would be better to buy a car if this is the case. The more authentic information about car leasing you know, the more likely people are to consider you a car leasing expert. Read on for even more car leasing facts that you can share. Take some time to compare prices. Visit your local car dealer and ask about a particular model that you are keeping an eye on. Ask about the rate if you will lease or buy a car. Comparing prices will give you an idea of the option that is more suitable for you. If you want to drive home the latest car models every time a new one comes out, then car leasing is the answer. It is not a good idea to buy a new model if you know that as soon as a newer model comes out, you would be changing vehicles anyway. Study your lease contract and take a look at the rates if you will lease the car for two, three or four years. A good rule to apply is that the shorter the period, the better the rates your Vehicle Finance will be. Also, if you will lease the car for more than two years, the vehicle might be susceptible to engine problems which you would want to avoid.
