Audio electrical or electronic equipment means of some kind. That amplify the audio signal. Or the deals with the process of sound broadcasting relay amplifier, etc.
.
type of audio sound that there are several types of By may, according to the characteristic function as follows:
.Signal source device, a device the signal by may be the source signal. Or receiving signals from the radio waves, such as
record player, cassette cassette machine, CD player, DVD player
.Radios, TV, satellite receiver equipment configuration.
signal amplifier or convert signals depending on usage. Such as
preamplifier, power amplifier, the equalizer, mixer,Surround sound processor
broadcasting equipment. As the end of the audio system. A relay final results came out, which is the speaker. It
.However, there are also other devices in the audio system such as microphones, cables, signal cables, etc. ชนิดของเครื่องเสียง
.The use of the transistor. A commonly used one, because the number of transistors to be used there. Can select and electronic circuit design has wide sound quality good, high gain and low distortion problem to repair complicated.Know it widely used in general. The highlight of a transistor amplifier The eclipse is able to increase the rate of expansion of wide expansion easy and cheap!
.The use of MOS FET. A start circuit, the used recently. Popular for a while. At present, the popularity in the use of power MOS fate decreased.The circuit design, increasing the gain, the repair is not wide and find a spare hard. But there are many advantages the specifications that transistor. Rate distortion ต้ำ. Noise affecting the expansion.There is sensitivity to amplify the signal is high. Able to gain many sectors
.
.The use of IC (INTERGRATED AMPLIFIER). As the extension is just more popular. The equipment the transistor moss phase included in IC Power Amp, the advantages of the extended approach is effective IC amplifier than moss fate.IC. Distortion caused the decline. Can add various control system. Response frequency sounds good. But the disadvantage is the high gain difficulty. Spare parts in the repair may be rare.IC is available in is medium not gain very high. Not used for a long time and continuous
