Title (EN) CONDENSER MICROPHONE AND ELECTRONIC DEVICE
(FR) MICROPHONE À CONDENSATEUR ET DISPOSITIF ÉLECTRONIQUE
(ZH) 电容式麦克风及电子装置
Abstract:
(EN) The present invention provides a condenser microphone, comprising a substrate, a back plate provided on the substrate, and a diaphragm; the back plate is provided on the upper side and/or the lower side of the diaphragm; and a protruding layer or a corrugated membrane structure layer is provided on the diaphragm. The above invention is capable of increasing the area of the diaphragm and the side capacitance of the condenser microphone, and achieving the effect of improving the sensitivity of the condenser microphone.
(FR) La présente invention concerne un microphone à condensateur, comprenant un substrat, une plaque arrière disposée sur le substrat, et un diaphragme; la plaque arrière est disposée sur le côté supérieur et/ou le côté inférieur du diaphragme; et une couche en saillie ou une couche de structure de membrane ondulée est disposée sur le diaphragme. L'invention ci-dessus est capable d'augmenter la surface du diaphragme et la capacité latérale du microphone à condensateur et d'obtenir l'effet d'améliorer la sensibilité du microphone à condensateur.
(ZH) 本发明提供一种电容式麦克风,包括基底、设置在基底上的背极板以及振膜;背极板设置在振膜的上侧和/或下侧;并且,在振膜上设置有突出层或者纹膜结构层。利用上述发明能够增加振膜的面积以及电容式麦克风的侧面电容,达到提高电容式麦克风灵敏度的效果。
