    摘要: A piezoelectric ceramic loudspeaker headphone structure includes a positioning frame, a steel sheet and a vibrating member. A step portion is disposed in an inner edge at the rear of the positioning frame. The steel sheet has an area approximately equal to that of the positioning frame and is disposed with a sound-making member stacked by a plurality of ceramic material layers. A lead wire is welded to the sound-making member. The vibrating member is a sheet body and has an area approximately equal to that of the step portion of the positioning frame. The steel sheet is disposed at a front edge of the positioning frame. The vibrating member is embedded in the step portion of the positioning frame, and thus a sound-making module is formed. The sound-making module is assembled to a headphone, and after the sound-making member receives an audio signal, a sound is guided out through response of the vibrating member. Therefore, the headphone is free of magnetism without influencing electronic products such as i-pad, i-phone, mobile phones or notebook computers, and is thinned due to omitting voice coils, which thus can be conveniently carried along.

    摘要翻译: 压电陶瓷扬声器耳机结构包括定位框架,钢板和振动构件。 台阶部分设置在定位框架后部的内边缘。 钢板的面积大致等于定位框架的面积,配置有由多个陶瓷材料层堆叠的声音构件。 引线焊接到声音构件。 振动构件是片体,并且具有与定位框架的台阶部分大致相等的区域。 钢板设置在定位框架的前缘。 振动部件嵌入定位架的台阶部,形成发声模块。 声音模块被组装到耳机,并且在声音构件接收音频信号之后,通过振动构件的响应引导声音。 因此,耳机没有磁性而不影响诸如i-pad,i-phone,手机或笔记本电脑的电子产品,并且由于省略音圈而变薄,因此可以方便地携带。
