Electronics audio amplifiers have many functions in the audio applications. In a public address, the loudspeakers are used to reinforce the sound so that it can be audible to the whole throng of people. Electronics audio amplifiers can also be used to increase the amplitude of the recorded music. The main function of electronics audio amplifiers is to amplify the magnitude of a sound signal in response to a specific input signal. Therefore, with the development of this technology, the singers or the political figures can transfer their messages to the people through this amazing device.
Classifications Of The Electronics Audio Amplifiers:
Classification is mainly based on the amount of time the output devices work in one complete cycle of the signal swing. Electronics audio amplifiers can be broadly classified into two ways. Firstly, they can be classified by their function. It implies that either they are voltage amplifiers or power amplifiers. Secondly, they can be classified by their frequency range. However, in both of the amplifiers, voltage amplifier and power amplifier, the output signal is always greater than the input signal.
How Does The Electronics Audio Amplifiers Operate:
All the electronics audio amplifiers work in the same method. There are few steps involved in the sound reproduction and they are:
* The microphone diaphragm is moved back and forth by the sound waves.
The microphone converts this movement into the electrical signal. The fluctuation of electrical signal result in the production of compressions and rarefactions of the sound wave.
* The electrical signal is, then, converted into a pattern in any medium by the recorder.
* The pattern is reconverted into the electrical signal by the player (e.g. tape deck) and electricity relocates the speaker cone backward and forwards. The resulting change in the air pressure will be recorded by the microphone.
Uses Of The Electronics Audio Amplifiers:
The electronics audio amplifiers are employed in many different types of the electronic devices. The electronics audio amplifiers strengthen the weak signal such as that of microphone, tape player, radio tuner, compact disk player or to drive the loudspeaker into a strong signal. Electronics audio amplifiers can be also placed in the head sets and mobile phones. It also finds its applications in the hearing aid devices which enhances the loudness of the sound. All military voice communication systems, even toys and many other appliances use electronics audio amplifiers
