The frequency response range of mid-range speakers is 256-2048Hz. Most of them are made of paper coils. The tone is clean, powerful and rhythmic. The frequency response range of the woofer is 16-256Hz. It is the material of the rubber basin ring, which has a strong sense of shock, majestic, powerful, plump and deep.
1、 What is the difference between a mid tone horn and a bass horn
1. Different frequency response ranges
(1) The frequency response range of the mid-range horn is between 256 and 2048Hz. The 256-512HZ is very powerful, the 512-1024HZ is very bright, and the 1024-2048HZ is very bright.
(2) The frequency response range of the woofer is 16-256Hz, of which 16-64HZ is deep and shocking, 64-128HZ is rich, and 128-256HZ is full.
2. The edge materials of paper pots are different
(1) Most midrange speakers are made of paper.
(2) The bass horn is made of rubber basin ring.
3. Different functions
(1) The vocal reproduction of mid-range speakers is more realistic, with clean, powerful voice and strong rhythm.
(2) The bass speaker has a strong sense of shock, powerful, plump and deep.
2、 Function and structure of low pitch loudspeaker
1. Function of the woofer
The woofer is a woofer unit in the loudspeaker. It is replayed through the low-frequency signal output from the frequency divider (the frequency range is generally 20Hz-150Hz). Generally speaking, the larger the diameter of the woofer, magnet and voice coil, the better the performance and transient characteristics of the low-frequency playback, and the higher the sensitivity.
2. Structure of the woofer
(1) The structural form of the woofer is mostly cone basin type, and there are a few flat plate types. There are many kinds of vibration membranes of the woofer, including aluminum alloy vibration membrane, aluminum magnesium alloy vibration membrane, ceramic vibration membrane, carbon fiber vibration membrane, bulletproof cloth vibration membrane, glass fiber vibration membrane, propylene vibration membrane, paper vibration membrane, etc.
(2) The bass units using aluminum alloy diaphragm and glass fiber diaphragm are generally small in caliber and have a relatively large bearing power, but the bass units using reinforced paper pots and glass fiber diaphragm are accurate in timbre when replaying music, and the overall balance is also good.
3、 Function and Structure of Mid tone Horn
1. Function of mid-range horn
The mid-range loudspeaker is used to realize the frequency connection between the bass loudspeaker and the tweeter when playing music. The mid-range loudspeaker unit in the vehicle loudspeaker is used to play back the mid-range signal (generally 150Hz-5KHz) output from the frequency divider. Because the IF occupies the dominant range of the entire sound range and is more sensitive to the human ear's IF than other frequency bands, the requirements for the sound quality of the mid-range speaker are high.
2. Structure of mid-range loudspeaker
Generally, there are two types of vehicle mid-range speakers: cone cone and dome, but their size and bearing power are larger than those of tweeters and they are suitable for playing mid-range audio. The diaphragm of the mid-range speaker is mainly made of soft materials such as paper cone and silk film, and occasionally there is a small amount of alloy dome diaphragm.
