Mention of the clock,Christian Louboutin Pump With Studs Trim, we'll be thinking of vibration. Mechanical watches use mechanical vibration,sandals high heels shoes, electronic watch,christian louboutin babel suede boots, of course is the use of electrical oscillation. The first oscillator circuit is constituted by the inductors and capacitors,Christian Louboutin Delic Leather Pumps Black, called the LC circuit, but its frequency stability is not good,Christian Louboutin Claudia Ankle-Strap Sandals Red, and later,christian louboutin pointed pumps, scientists use LC instead of quartz crystal oscillator, frequency stability is greatly improved. Rules hexagonal quartz crystal. In a certain position on the quartz crystal cut is called under the thin quartz chip. Quartz has a nifty feature: If the chip to mechanical force,Christian Louboutin Black Patent Leather Simple Pumps, the corresponding direction in the electric field is generated. This physical phenomenon is called "piezoelectric effect." When the quartz plate connected to the AC field polar. When the external alternating voltage frequency equal to the natural frequency of quartz, it will have resonance. This phenomenon is called "piezoelectric resonance." Using this stable oscillation,christian louboutin pointed toe pump red, people created a very high precision electronic watches and quartz clocks.
Electronic watch is 50 years of the 20th century began to appear in the new timer. The earliest a spreadsheet called "balance spring electronic watch", which was born in 1955. The watch balance wheel instead of electromagnetic winding drive to balance spring as the oscillator,Christian Louboutin Discolilou 140 Sandals White, micro batteries for energy,christian louboutin glitter-covered leather peep-toe pumps, driven by electronic circuits work balance. Part of its travel time is identical with the mechanical watch,Christian Louboutin Privatita platform slingbacks Green, known as the first generation of electronic watches. In 1960, the United States Bulova Corporation began selling the first "electronic tuning fork watch." This watch as a metal tuning fork oscillator,Christian Louboutin No Barre Mary Jane Pumps Grey, electronic circuit output pulse current,Christian Louboutin Miss Clichy 140 boots, so that the mechanical tuning fork vibration. Electronic watch than the simple pendulum wheel,Christian Louboutin Straratata Platform Sandals Blue, travel time more accurately,christian louboutin pointed toe pink pumps, known as the second generation of electronic watches. In 1969, Seiko introduced the world's homes the first quartz digital watches. The emergence of quartz digital watches, watches and clocks immediately became a mainstream product, it goes accurate,Christian Louboutin C'est Moi Ankle Boots Brown, simple and easy way to a second-generation electronic watches,Christian Louboutin Circus Cutout Wine Ankle Booties, mechanical watches and even eliminated. Quartz,Christian Louboutin Glitter Peep-toe Pump Purple, also known as "crystal vibrations electronic watch" because it is the use of crystal film "the oscillation phenomenon" to timing. Augmented by the external crystal when the voltage response will produce distortion and stretching; if compressed crystal,Christian Louboutin Deva 120 Suede Fringed Boots, it will produce electricity at both ends of the crystal. In many such properties can also be seen on the crystals, known as the "piezoelectric effect." Quartz watch is the use of periodic continued,Christian Louboutin Nude Engin 120 Studded Pumps, "the oscillation" of the crystal, brings us the exact time.
