摘要： A structure of an electrostatic speaker and a manufacturing method thereof are provided. In the electrostatic speaker, an electrode and a vibrating film are disposed closely, and electrostatic force of the vibrating film may make the vibrating film contacting with the electrode such that the speaker would fail to generate the sound. Thus, the invention provides a spacer structure and a manufacturing method thereof. Various patterning or height changes and other designed are performed to place the spacer between the electrode and the vibrating film, so as to prevent the electrode from contacting with the vibrating film. The disposition of the spacer is expected to enhance frequency response or sound volume of the speaker.

摘要： 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.
