【摘要】 片式压电平板扬声器是继传统动圈式扬声器之后发展起来的新型扬声器,具有电磁干扰小、功率低、结构简单、重量轻、尺寸薄的优点.压电扬声器的振子直接决定了其片式压电平板扬声器的性能,本文从PS46×46片式压电扬声器的材料、工艺、结构及应用等方面进行了研究分析.更多还原

【Abstract】 With the advantage of small electromagnetic interference,low power,simple structure,light weight,and thin dimensions,chip piezoelectric panel speaker is a new speaker developed after the traditional moving coil loudspeaker. Piezoelectric speaker vibrator directly determines the pressure performance of the chip electric flat panel loudspeaker. The present paper analyzes the PS46x46 of chip pressure electric loudspeaker of the material,process,structure and application.更多还原
