4 different speaker categories

2021-06-04 381
Speaker refers to a device that converts audio signals into sound. In layman's terms, it means that the main speaker cabinet or the subwoofer cabinet has its own power amplifier, and the audio signal is amplified and processed by the speaker itself to reproduce the sound.

Speaker classification

Speaker classification 1. According to the occasion of use: it is divided into two categories: professional speakers and home speakers. Household speakers are generally used for home playback. They are characterized by fine and soft playback sound quality, more refined and beautiful appearance, not too high playback sound pressure level, and relatively little power. Professional speakers are generally used in professional entertainment venues such as dance halls, karaoke, theaters, halls and stadiums. Generally, professional speakers have high sensitivity, high sound pressure, good power, and high power. Compared with household speakers, their sound quality is harder and their appearance is not very delicate.

Speaker classification 2. According to the audio frequency: can be divided into full-band speakers, bass speakers and subwoofer speakers. The so-called full-band speaker refers to the sound that can cover the low, mid and high frequency ranges. The lower limit frequency of the full-band speaker is generally 30Hz -60Hz, and the upper limit frequency is 15KHz-20KHz. In general small and medium-sized audio systems, only one or two pairs of full-band speakers can be used to fully take on the playback task. Bass speakers and subwoofers are generally dedicated speakers used to supplement the low-frequency and ultra-low frequency playback of full-band speakers.

Speaker classification 3. Divided by purpose: Generally, it can be divided into main playback speakers, monitor speakers, and return speakers. The main sound box is generally used as the main sound box of the sound system to undertake the main sound reproduction task. The performance of the main playback speaker has a great impact on the playback quality of the entire audio system, and a full-band speaker plus a subwoofer speaker can also be used for combined playback.

Speaker classification 4. According to the cabinet structure: it can be divided into sealed speakers, inverted speakers, labyrinth speakers, sonic tube speakers and multi-cavity resonant speakers. Among them, the most used in professional speakers is the inverted speaker, which is characterized by wide frequency response, high efficiency, and large sound pressure, which is in line with the type of professional audio system speakers, but because of its low efficiency, it is less in professional speakers. Application, mainly used for household speakers, only a few monitor speakers adopt a closed box structure. The sealed speaker has the advantages of simple design and manufacture, wide frequency response, and good low-frequency transient characteristics, but it has higher requirements for the dial unit. At present, in all kinds of speakers, inverted speakers and sealed speakers account for the majority of the proportions. Other types of speakers have many structural forms, but they account for a small proportion.
