The loudspeaker is also known as the "horn". Is a very common electro-acoustic transducer device, in the sound of electronic and electrical equipment can be seen in it. The loudspeaker is a kind of transducer device that transforms electrical signals into sound signals, and the performance of the loudspeaker has a great impact on the sound quality. Speaker in the audio equipment is one of the weakest devices, and for the sound effect, it is one of the most important components. There is a wide range of speakers, and prices vary greatly, audio electricity through electromagnetic, piezoelectric or electrostatic effects, so that its paper cone or diaphragm vibration and resonance with the surrounding air (resonance) and emit sound.
