ACOUSTIC TRANSDUCER WITH HIGH SENSITIVITY |
| 摘要 |
An acoustic transducer with high sensitivity includes a base plate, a back plate and a vibrating membrane. The vibrating membrane is peripherally fixed to the base plate and covers an opening of the base plate. The back plate has a positioning member connected between the back plate and the vibrating membrane, so as to define at least one vibratile portion that is arranged annularly by a plurality of elastic members. Thereby, the vibratile portion has a reduced deformable width and increased rigidity, so can effectively improve its acoustically receiving sensitivity and signal-to-noise ratio. |
