电吉他音箱详解(对乐器感兴趣的同学注意了!由此及彼了!)（Electric guitar Xiangjie (interested in music students pay attention! From here!)） A friend who has played an electroacoustic guitar must know that even without the amplifier and the speakers, even the most expensive piano in the world, Just a dumb man. For electroacoustic guitars, the speakers are not only their mouthpiece, but also good sound One of the mysteries. Whats an electroacoustic guitar box? Acoustic guitar and acoustic guitar is the biggest difference with the special pickups, its interior is composed of a permanent magnet and coil composition, through Strings vibrate to cut lines of force and produce the same electronic signals as audio frequencies. However, the electronic signals obtained are very weak If it is directly attached to the speaker, it can not be converted into sound waves at all. Only by amplifying these weak currents It can drive the speaker to achieve electroacoustic conversion, and the equipment for this work is an electroacoustic guitar speaker. Front stage amplification and power amplification The general household high fidelity speakers and amplifiers are separate, but the designers of the guitar speakers are in order to ensure the uniformity of sounds And the convenience of handling, usually amplifier parts and speakers tied to manufacture, even if not in the same box, designers are also more The half will fix the two parts together. The amplifier circuit built in the loudspeaker box is composed of two parts: the front amplifier and the power amplifier A. The first stage amplifier for weak signal output from the pickup line in shaping amplifier, often with a tone (EQ) and lost True (Booster) circuitry is one of the secrets of highly skilled guitarists. The power amplification is responsible for the contents that will be determined by the front stage The circuits processed signal is amplified enough to drive the speakers audible output to achieve the final electroacoustic conversion.
