1. Overview
The speaker system by one or several speakers and appropriate accessories, such as baffles, speakers, and other components of the crossover network, as a driving circuit and the ambient air coupling between devices. Purpose is to obtain a frequency characteristic of the sound field distribution, and special sound effects desired. A typical speaker with a direct electric Speakers speaker and various combinations of electric speaker. Only the direct sound power radiated size speaker, and the sound pressure level in the service area larger unevenness. Larger acoustic power using electric horn loudspeaker can substantially obtain a sufficiently large and uniform acoustic intensity of the sound within the sound field area, but the frequency range is narrow, can not meet the requirements of high-quality music sound. Thus, the speaker often used in combination. This will not only increase the radiation wide frequency range and sound power. Application of horn speaker enclosure can be improved and the low-frequency characteristics of the speaker, directivity and efficiency; various rear speaker group, it can be further controlled acoustic power and radiation characteristics. As special sound effects, such as sound from a long distance and the case of strong noise, so to several hundred kilowatt sound power, pneumatic loudspeaker may be used at this time.

the book details the speaker cone, dome-shaped speaker, horn speakerAnd a variety of structure-borne sound speaker box, working principle and characteristics, as well as with the speaker about the acoustics knowledge. The book is divided into 16 chapters, including the physical process of sound reproduction, psychoacoustic, acoustic nature of the program, there should be performance hi-fi speakers, speaker cone, dome-shaped speaker, horn speaker, speaker box, speaker system, monitor speaker other types of speakers, amplifiers and speakers, reproducing sounds acoustic properties of the room, the speaker sound measurement system, headphones and speakers characteristics.
This book is available speaker factory technicians and workers, researchers and university-related research institutes of relevant professional teachers and students to read and reference. For the majority of speaker users also have some reference value.
