SUMMARY

China is known for producing many products used in the world today. Ranging from fashion to electronic appliances and even automobiles are all produced in China. China’s industry encompasses mining, manufacturing, construction, and power. The country has succeeded in creating a name for itself in the exportation of quality products worldwide.

Today, China is the leading manufacturer of cement, steel, and other major products. Since state-owned enterprises dominated 1978 products, the economic reforms brought about private entrepreneurs and foreign investments.

China has contributed significantly to the gross value of the industrial output, about 13.3% of the annual output between 1950 to 1979. Their impact has been greatly felt in the area of electric cars as this country was part of the first to accept the use of electric cars in the world, thereby influencing other countries to join.

In addition, China has also contributed to the area of producing electronic devices. I proudly can say that China’s electronic devices are one of the best you can buy in the market today. China’s electronic products are known for durability and delivering quality services. It is why I will be introducing you to some of the Amplifier Manufacturers in China and why you should buy Amplifiers Manufactured in China.

WHAT ARE AMPLIFIERS

Amplifiers are electronic devices used for the increasing of electronic signals, used chiefly in sound production. A device consisting of an amplifier combined with a loudspeaker and used in increasing the volume of the sound produced by electric guitars and other musical instruments.
Amplifiers are usually designed to function in a specific application, for example, radio and television transmitters and receivers, high-fidelity (“hi-fi”) stereo equipment, microcomputers and other digital equipment, and guitar and other instruments amplifiers.

Uses Of Amplifiers

Amplifiers are used to increase the power, current, or voltage of a signal. Amplifiers are used in music equipment, electronic devices such as radio receivers, audio equipment, and computers to increase the amplitude of a signal.

WHAT IS AMPLITUDE?

There are various definitions of amplitude depending on the field of study or profession; some common definitions are given below:
According to Britannica, in physics, the maximum displacement or distance moved by a point in a vibrating body or wave is measured from its equilibrium position. It is equal to one-half the length of the vibrating path. Sources generate waves, and their amplitude is proportional to the amplitude of the source.
Google defines amplitude in astronomical terms as the angular distance of a celestial object from the horizon’s true east or west points at rising or setting.

HOW DO AMPLIFIERS WORK?

An amplifier takes an input signal from a source, such as a laptop, turntable, or CD player, and creates a larger copy of the original signal before it’s sent to the speakers. It gets the power to do this from your mains electricity, sent directly to the power supply within the amplifier.

Classes of Audio Amplifiers

There are various classes of amplifiers
● Class A Amplifiers
● Class B Amplifiers
● Class AB Amplifiers
● Class D Amplifiers
● Class G Amplifiers
● Class DG Amplifiers
● Class H Amplifiers
● Other classes are the modern amplifiers which switch topologies, and PWM (Pulse Width Modulation) technique to drive the output load.

Types of Audio Amplifiers

There are six types of Amplifiers which are also often described in system or block diagrams by name;
● Amplifier
● Audio Frequency Amplifier.
● Intermediate Frequency Amplifier.
● R.F. Amplifier
● Ultrasonic Amplifier.
● Operational Amplifier.
