Miniature acoustic generator

微型发声器

Abstract

本实用新型涉及电声能发声领域,具体指一种微型发声器,包括安设磁路系统的盆架、磁路系统具有磁间隙,在盆架的侧壁上开设有与所述磁路系统的磁间隙贯通的透声孔,所述透声孔设有倾斜面,这样可节省发声器在前盖开设的声腔,降低整体发声器的高度,可将发声器作的更为轻薄化,以适应日趋安设空间缩小的趋势。
The utility model relates to the field of acoustic generation by electroacoustic energy, in particular to a miniature acoustic generator, comprising a frame which is provided with a magnetic circuit system, wherein the magnetic circuit system is provided with a magnetic gap; the side wall of the frame is provided with a sound transmission hole communicated with the magnetic gap of the magnetic circuit system; and the sound transmission hole is provided with an inclined surface. Therefore, an acoustic cavity is not required for being arranged on a front cover of the acoustic generator, thereby reducing the height of the entire acoustic generator; and the acoustic generator is made into a thin type so as to be fit for the tendency of a mounting space gradually reduced.
