摘要： An electret loudspeaker device including a diaphragm, a first perforated electrode and a first spacer is provided. The diaphragm has an electret layer and an electrode layer. The first perforated electrode is stacked on a side of the diaphragm near the electret layer, and has multiple holes. The first spacer is stacked between the diaphragm and the first perforated electrode, and includes a first distribution area and plural second distribution areas. The first distribution area has first openings penetrating through the first spacer, and each first opening has a first opening space volume between the diaphragm and the first perforated electrode. Each second distribution area has second openings penetrating through the first spacer, and each second opening has a second opening space volume between the diaphragm and the first perforated electrode. A difference between the first and the second opening space volumes is greater than 10%.

摘要： An electret loudspeaker device including a diaphragm, a first perforated electrode and a first spacer is provided. The diaphragm includes a first electret, a second electret, a polymer layer and an electrode layer. At least one layer of the first electret or the second electret is formed by expanded polytetrafluoroethylene. The second electret is stacked on one side of the first electret, while the electrode layer is stacked on the opposite side of the first electret. The polymer layer is made of a hydrophobic material and is disposed on the second electret. The first perforated electrode is stacked on a first spacer and close to the polymer layer. The first spacer disposed between the diaphragm and the first perforated electrode supports the first perforated electrode over the diaphragm and defines a first chamber. A fabrication method of the electret loudspeaker device is also provided.
摘要翻译：提供了包括隔膜，第一穿孔电极和第一间隔件的驻极体扬声器装置。隔膜包括第一驻极体，第二驻极体，聚合物层和电极层。第一驻极体或第二驻极体的至少一层由膨胀聚四氟乙烯形成。第二驻极体堆叠在第一驻极体的一侧上，而电极层堆叠在第一驻极体的相对侧上。聚合物层由疏水材料制成，并设置在第二驻极体上。第一穿孔电极堆叠在第一间隔物上并靠近聚合物层。设置在隔膜和第一穿孔电极之间的第一间隔件支撑隔膜上的第一穿孔电极，并限定第一室。还提供了驻极体扬声器装置的制造方法。
