What is a sound transistor?

transistors are electronic devices that perform switching or reinforcement on electric signals. In the simplest point of view, the audio transistor is any transistor designed to work with audio signals. The sound transistor is usually a amplification type transistor used to strengthen weak sound signals, for example on radio, levels usable by other electronic devices such as filters, equalizers, other amplifiers and speakers. They are made of three pieces of either Germania or silicon, which were treated either positively or negatively charged material. In the NPN sound transistor, two are negative and one is positive.

The three transistor pieces are then fused together in the line, with a positively charged section inserted between two negatively charged sections and creates two connecting points. Furthermore, the guide wire is connected to each of the three parts of the compound material. Finally, when the entire transistor is covered with an offensive cover that will also help himBaging heat, the transistor is completed. The positive part is the base of the transistor and is a place where the voltage will be applied to increase the incoming signal. Finally, the remaining negatively charged section is the emitter of the transistor and from there a reinforced audio signal passes from the transistor to the rest of the perimeter.

In amplification applications, the transistor receives an audio signal through its collector and a separate signal is applied to its base. The output on the transistor emitter will be identical to the collector's signal, except that it increases the power by an amount of direct signal applied to the base. In addition, a change in the signal applied to the base will change the amplification of the sound signal leaving the transistor.

transistors may vary in many ways. Depending on their design, they may have a different amount of amplification potential and signal loyalty. Sound transistors tend to be discreet, it is isolated and have inYanning properties of signal loyalty.

There are a number of different types of sound transistors, each performing a given function for processing the audio signal. The difference between these types is often only things. For example, one type can only amplify the audio signal to a slight level, for example in the preamplifier, with a sufficient amount of energy control.

6 Sometimes these types of transistors can create a signal that IS hundreds of watts in force, for example in the case of amplifiers used at concerts. In addition, new types of transistors, such as field transistors with wider abilities ranges, find roles as sound transistors capable of taking a small signal to the speaker control point.
