According to the working principle, it can be divided into electric speakers and electrostatic speakers, etc.; according to the beginning of the diaphragm, it can be divided into cone type, dome type, flat type, belt type, etc.; according to the form of magnetic circuit, it can be divided into external Magnetic type, internal magnetic type, dual magnetic circuit type and shielded type; according to the nature of the magnetic circuit, it can be divided into ferrite magnets, neodymium boron magnets, and alnico magnet speakers; according to the diaphragm material, it can be divided into paper and non- Paper cone speakers, etc. It can be divided into subwoofer speakers, center speakers, satellite speakers, etc. by use; distinction by structure can be roughly divided into two categories: coaxial speakers and package speakers. All speakers can be regarded as structurally. It is a variant of these two types of speakers.
A coaxial speaker is a speaker in which several sound units are arranged as a whole. For example, the tweeter unit is installed inside the midrange unit; while the packaged speaker is the opposite of the coaxial speaker, and the sound unit is arranged separately, usually with There is a frequency divider to separate the input audio signal into different parts such as treble, midrange, and bass, and then send them to the corresponding high, medium and woofer unit for playback. This frequency divider is passive Frequency converters are generally unable to meet player-level requirements, but they are sufficient as ordinary applications.
The tweeter of the coaxial speaker is located above the speaker. The price is economical and there is a market. It is suitable for friends who are initially upgrading the car audio. Because it is easy to drive, but because the treble and mid-bass are mixed and interfere with each other, the sound effect is not as pure as a suit speaker. In addition, its sharp tone and insufficient sound field positioning are also its shortcomings. Its musical effects are not as natural as the suit speakers. Although some car audios worth tens of thousands of yuan will also use coaxial speakers, generally speaking, the split is higher than the coaxial speakers.
Set speakers are widely used in car audio, but they are not common in home audio. Because car audio and home audio are two different things, home audio corresponds to a standard space that can fully display the effect of the speaker. And there are many parts on the car, including the instrument panel, seat, etc., which hinder the frequency of the speaker. Therefore, the car audio industry has researched and produced a split package speaker. Generally speaking, the listening effect of the package speaker is better than that of the coaxial speaker. Most audiophiles who have higher requirements on the audio level and want to configure a set of mid-to-high-end speakers choose package speakers.
