The Main Classifications of the Loud Horn Speaker

There are many kinds of loud horn speaker, which can be divided into electric (moving coil type), electrostatic (capacitive type), electromagnetic (tongue spring type) and piezoelectric (crystal type) according to the principle of energy exchange. The latter two types are mostly used in rural wired broadcasting networks. They can be divided into low-frequency loudspeakers, medium-frequency loudspeakers and high-frequency loudspeakers according to the frequency range, which are often used as combinations in loudspeakers.

According to the energy exchange mechanism and structure, the electric loudspeaker has the advantages of good electro-acoustic performance, firm structure, low cost and so on, and is widely used in many fields, such as the drive coil type (electric type), the capacitive type (static type), the piezoelectric type (crystal or ceramic type), the electromagnetic type (pressure spring type), the electro-ionic type and the pneumatic loudspeaker.

The loud horn speaker is divided into paper basin, horn and diaphragm according to the sound radiation material; circular, elliptical, double paper basin and rubber folding ring according to the shape of the paper basin; bass, mid-tone and high-tone according to the working frequency, and some are also divided into tape recorder special, television special, ordinary and high-fidelity loudspeakers; low impedance and high impedance according to the impedance of the voice coil; direct and environmental sound according to the effect.

The loud horn speaker is divided into built-in loudspeaker and external loudspeaker, and external loudspeaker is generally referred to as the speaker. Built-in speaker refers to the MP4 player with built-in speaker, so that users can not only listen to the voice of the MP4 player through the headphone jack, but also through the built-in speaker. The MP4 player with built-in speaker can avoid the inconvenience of long-time earphones without external speakers.
