  • Patent number: 8138034
    Abstract: A flexible electret transducer assembly including an electrical backplate and a membrane made of an electret material is disclosed. A plurality of spacers is formed on a surface of the electrical backplate in a longitudinal or latitudinal direction, and the spacers are used for supporting a vibrating room of the membrane. A working area of the membrane is formed between adjacent spacers, and in each of the working area, the space between the electrical backplate and the membrane is smaller than that in a conventional electrostatic speaker. The spacers between the electrical backplate and the membrane are mass produced through a stamping process. Thereby, an accurate space between the electrical backplate and the membrane can be maintained and accordingly the audio quality can be improved. In addition, a speaker including the flexible electret transducer assembly and a method for fabricating the flexible electret transducer assembly are also disclosed.
