SILICON SPEAKER |
摘要 |
The present invention provides a silicon speaker comprising an MEMS acoustoelectric chip and a PCB substrate, wherein the MEMS acoustoelectric chip comprises a corrugated diaphragm on a silicon substrate; and one side surface of the MEMS acoustoelectric chip is metalized, and the metalized side surface of the MEMS acoustoelectric chip is connected with the PCB substrate. The corrugated diaphragm is electrically conductive and interconnected with metal paths on MEMS acoustoelectric chip, which is led out to a first PCB metal path as one electrode. A second PCB metal path below the MEMS chip forms another electrode of the electrostatic actuator. The silicon speaker provided by the present invention lowers manufacturing costs of the speaker, and allows the diaphragm to generate high and repeatable/reliable sound pressure upon large displacements so as to improve the sounding effects of the speaker. |
