Mention of the clock, we'll be thinking of
vibration. Mechanical watches use mechanical vibration, electronic watch, of
course is the use of electrical oscillation.These quartz crystal resonator can be found at
Nordstroms department store all over the world. The first oscillator circuit is
constituted by the inductors and capacitors, called the LC circuit, but its
frequency stability is not good, and later, sThese China garlic are high in demands and can
already be purchased anywhere.cientists 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,
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 stableoscillation, 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, micro batteries for energy, driven by electronic
circuits work balance. Part of its travel time is identical with the mechanical
watch, 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, electronic circuit output
pulse current, so that the mechanical tuning fork vibration.You could always
search for wholesale suppliers directly on a specific wholesale search Crystal Filter or
directory. Electronic watch than the simple pendulum wheel,travel time more
accurately, 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, simple and easy way to a second-generation electronic
watches, mechanical watches and even eliminated. Quartz, also known as "crystal
vibrations electronic watch" because it is the use of crystal film
"theoscillation phenomenon" to timing. Augmented by the external crystal when
the voltage response will produce distortion and stretching; if compressed
crystal, 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, "theoscillation" of the
crystal, brings us the exact time.
