Abstract

The invention discloses a novel linear medium-high frequency compressed drive, comprising a magnetic circuit structure, wherein the output end of the magnetic circuit structure is provided with a voice coil; the output end of the voice coil are provided with diaphragms; the output ends of the diaphragms are provided with phase plugs; throat covers cover the phase plug; and the mating surfaces of the phase plug matched with the diaphragms and the throat covers are rectangular or long-runway-shaped. Such generating parts as the phase plug, the throat covers and the like of the drive are rectangular or long-runway-shaped, thus ensuring the drive to directly radiate near-linear sound waves in the long-axis direction, avoiding such minus effects as sound wave interference, offset, superposition and the like occurring when the medium-high frequency sounds are played and ensuring good played sound quality. The drive is extensively applied to various sound systems as a linear compressed sound source transducing device with excellent performance.

Description

technical field [0001] The invention relates to an electro-acoustic transducer, in particular to a compression linear sound source-transducer with a new structure. Background technique [0002] Ordinary electroacoustic transducers are similar to point sound sources, and what they emit is spherical sound waves. This ordinary electroacoustic transducer attenuates seriously with the increase of the diffusion distance. When high sound pressure is required for long-distance transmission, the easiest way is to arrange multiple speakers (transducers) to increase the output sound pressure. But what follows is that when ordinary electro-acoustic transducers work in the middle and high frequency bands, the wavelength of the sound wave is similar to the distance between the speakers of the point sound source, which will be due to the distance difference between the single speakers. Phase interference is generated, thereby producing sound wave interference, cancellation or sound wave s...
