1. Divided by occasion of use
According to the occasion of use, the audio is mainly divided into home audio and professional audio. Home audio is generally not demanding. It is used for daily amplifying and listening to music at home. The appearance is generally designed to be exquisite and beautiful, with various shapes, and the sound quality of playback sound will be better. Gentle and delicate, the playback sound pressure level is not high, and the power will be relatively small.
Professional audio is mainly used in professional places such as stage, song theater, karaoke, etc. The equipment used is mainly waterproof speakers. This kind of audio requires higher sensitivity and clear and loud sound, which needs to withstand higher power and sound pressure level. High, strong, usually larger in appearance, and simple in appearance.
2. Divided by box structure
According to the cabinet structure of the speakers in the audio system, it can be divided into sealed speakers, labyrinth speakers, inverted speakers, sonic tube speakers, and multi-cavity resonant speakers. Among them, the most used in professional audio is the inverted speaker, which is characterized by wide frequency response, high efficiency and loud sound pressure, which is in line with the speaker type of professional audio system.
The sealed speaker has the advantages of simple debugging, wide frequency response, and excellent low-frequency transient characteristics, but its requirements for the dial unit are relatively high, which is relatively rare in home scenes. At present, in various audio equipment, sealed and inverted speakers will be widely used, and speakers of other structures will not account for a large proportion.
3. Divided by audio frequency
According to the audio frequency, it can be divided into three types: full-range speakers, subwoofer speakers and subwoofer speakers. A full-range speaker refers to a sound that can cover all frequency bands from low to high frequencies. The lower limit frequency is generally 30Hz-60Hz, and the upper limit frequency is 15KHz-20KHz.
Since the full-frequency audio covers a wide frequency band, only one or two pairs of full-frequency audio systems are required in a general audio system to fully assume the task of sound reproduction. Bass speakers and subwoofer speakers are generally dedicated speakers used to supplement the low frequency and ultra low frequency playback of full-band speakers. These two types of speakers are generally used in medium and large audio systems to assist in increasing the strength and strength of the main audio system. Shock etc.
