Introduction on classic audio loudspeakers
The classic audio loudspeakers are very commonly used electronic-acoustic transducer, which can be seen in electronic and electrical equipment that emits sound. The loudspeaker is a kind of transducer device that transforms the electric signal into the sound signal. The performance of the loudspeaker has a great influence on the sound quality. The speaker is the weakest component in audio equipment, and it is the most important component for audio effects. There are many types of speakers, and the prices vary greatly. Audio electric energy uses electromagnetic, piezoelectric or electrostatic effects to make the cone or diaphragm vibrate and resonate (resonate) with the surrounding air to produce sound.

Audio electric energy uses electromagnetic, piezoelectric or electrostatic effects to make the cone or diaphragm vibrate and resonate (resonate) with the surrounding air to produce sound.
Low-end plastic speakers have no sound quality at all because of their thin cabinets and inability to overcome resonance (some well-designed plastic speakers are far better than poor-quality wooden speakers); wooden speakers reduce the sound stain caused by cabinet resonance. The sound quality is generally better than plastic speakers.
Usually multimedia speakers are designed with a two-unit two-way frequency, a smaller speaker is responsible for the output of the mid-to-high range, and another larger speaker is responsible for the output of the mid-bass.
The components of a speaker of these two speakers should be considered when selecting speakers: The tweeter of multimedia active speakers is now mainly soft dome (in addition to the titanium dome used for analog sound sources, etc.), it can reduce high frequencies in conjunction with digital sound sources The coldness of the signal gives people a cold, slender, and ethereal feeling. Multimedia speakers now have soft dome tops such as better quality silk films and lower cost PV films.
The bass unit determines the characteristics of the sound of the speaker. It is relatively important to choose. The most common ones are the following: paper cones, paper cones, paper-based wool cones, and compacted cones.
The category of classic audio loudspeakers
The paper cone has natural sound, cheap, better rigidity, lighter material and high sensitivity. The disadvantage is that it has poor moisture resistance and is difficult to control during manufacturing. However, the top HiFi system made of paper cones abound, because the sound output is very average. Good reducibility.
Bulletproof cloth has a wider frequency response and lower distortion. It is the first choice for those who love strong bass. The disadvantages are high cost, complicated production process, low sensitivity, and poor light music effect.
The wool woven basin has a soft texture. It is very good for soft and light music, but the bass effect is not good, and it lacks strength and shock.
PP (polypropylene) basin, which is widely popular in high-end speakers, has good consistency and low distortion, and its performance is remarkable in all aspects. In addition, there are fiber diaphragms and composite material diaphragms that are rarely used in popular speakers due to their high prices.
The loudspeaker size is naturally the bigger the better, the large-caliber woofer can have better performance in the low frequency part, which can be selected in the purchase. Speakers made with high-performance speakers mean lower transient distortion and better sound quality. The speakers of common multimedia speakers' woofers are usually between 3 and 5 inches. Speakers made with high-performance speakers also mean lower transient distortion and better sound quality.
Our most common electric cone speaker. Electric cone loudspeakers are often referred to as paper cone loudspeakers in the past. Although the diaphragm is still dominated by paper cones in 2014, many polymer material and metal diaphragms have appeared at the same time. Cone loudspeakers are called the name symbol Actually. The cone loudspeaker is roughly composed of magnetic circuit system (permanent magnet, core column, magnetic conductive plate), vibration system (paper cone, voice coil) and support auxiliary system (centering support piece, basin stand, cushion edge), etc. Partial composition.
The basic features of classic audio loudspeakers
The speaker has two binding posts (two leads). When a single speaker is used, the two pins have no positive or negative polarity. When multiple speakers are used at the same time, the two pins have polarity.
The speaker has a paper cone, and its color is usually black and white.
The shape of the loudspeaker has several categories such as round, square and oval.
The back of the speaker cone is a magnet. The external magnetic speaker will feel the presence of magnetism when using a metal screwdriver to touch the magnet; the internal magnetic speaker does not have this feeling, but there is a magnet inside the housing.
The speaker is installed on the panel of the machine or inside the speaker.
