Headphone speaker manufacturers introduced to classify according to working principle: according to different working principles, speakers are mainly divided into electric speakers, electromagnetic speakers, electrostatic speakers and piezoelectric speakers.

1. Conical diaphragm speaker: The most widely used cone diaphragm speaker is the cone cone speaker. The speaker manufacturer's diaphragm is conical, which is the most common and widely used speaker in electric speakers, especially It is the most widely used as a subwoofer.
2, flat speaker: is also an electric speaker, its diaphragm is flat, the external vibration directly radiates sound waves.
Its flat diaphragm is a circular peak nest plate with a peak nest core made of aluminum foil and fiberglass on both sides. Its frequency characteristics are relatively flat, the frequency bandwidth and distortion are small, but the rated power is small.
3. Horn Speaker: The horn loudspeaker works the same as the electric cone speaker. The diaphragm of the horn loudspeaker is mostly dome-shaped, and can be other shapes. The difference between this type of speaker and other speakers is mainly in the way of sound radiation. The cone speaker and the dome speaker are directly radiated by the diaphragm to radiate the sound, which is direct radiation, and the horn speaker is the diaphragm. The generated sound is radiated into the space through the horn, which is indirect radiation. The biggest advantage of the horn loudspeaker is its high efficiency, low harmonic distortion, and strong directionality, but its narrow frequency band and poor low frequency response. Therefore, it is mostly used as a middle and high-pitched unit in a speaker system.
4. Ball-shaped speaker: The dome-shaped speaker is a kind of electric speaker, and its working principle is the same as that of the cone speaker. The distinctive features of the dome-shaped speaker manufacturers are good transient response, low distortion, good directivity, but low efficiency, often used as the middle and high-pitched units of the speaker system.
The frequency amplifier is divided into sound frequency: it can be divided into a woofer, a midrange speaker, a tweeter, a full-range speaker, and the like.
1. Headphone speaker manufacturer introduces midrange speaker: The speaker that mainly plays the intermediate frequency signal is called the midrange speaker. The midrange speaker enables the frequency connection between the woofer and the tweeter to replay music. Because the intermediate frequency occupies the dominant range of the entire range, and the human ear feels more sensitive to the intermediate frequency than other frequency bands, the sound quality of the midrange speaker is higher. There are paper cones, dome shapes and horns. As a midrange speaker, the main performance requirement is that the sound pressure frequency characteristic curve is flat, the distortion is small, and the directivity is good.
2, woofer: The main speaker that plays low-frequency signals is called the woofer, and its bass performance is very good. The woofer makes the lower limit of the low-frequency playback as far as possible, so the diameter of the speaker is relatively large. Generally, there are woofers of different caliber sizes such as 200mm and 300-380mm, which can withstand large input power. In order to increase the tolerance of the vibration amplitude of the paper cone, soft and wide supporting edges, such as leather edges, cloth edges, and insulating edges, are often used. In general, the larger the woofer's aperture, the better the low-frequency sound quality during playback, and the greater the input power.
3. Headphone speaker manufacturers introduce full-range speakers: Full-band speakers are speakers that can cover the bass, midrange and treble bands at the same time, and can play electrical signals in the entire audio range. The theoretical frequency range is from tens of Hz to 20 kHz, but in practice it is very difficult to use a single speaker, so most of them are made into double cone speakers or coaxial speakers. The double cone speaker is a small-diameter paper cone in the center of the large diameter of the speaker for reproducing high-frequency sound signals, which is beneficial to the upper limit of the frequency characteristic response. The coaxial speaker is mounted on the same central axis with two different woofer and tweeter.
4. Tweeter: A speaker that mainly plays high-frequency signals is called a tweeter. The tweeter makes the upper limit frequency of the high-frequency sounding reach the upper limit of the human ear hearing frequency of 20 kHz, so the aperture is small and the diaphragm is tough. Compared with the low and midrange speakers, the performance requirements of the tweeter are the same as those of the midrange unit, and the upper limit of the playback band is required to be high and the input capacity is large. Commonly used tweeters are in the form of a paper cone, a flat plate, a dome, and a ribbon.
