摘要:
An electrostatic speaker is constructed using a thin flexible membrane as the active member. This membrane is uniformly positioned against at least one printed circuit board containing at least one stator fixed in the PCB. Variations in structure are provided, all including at least one PCB and a membrane. In a preferred embodiment, intermeshing opposing ridges on the PCBs are adjacent to a central vibrating area of the membrane, and serve to position and tension the membrane. Attachment means connect the PCBs together, and electrical connections permit the passage of current to bias the membrane and to drive the stators to vibrate the membrane, producing acoustical output in the sonic or ultrasonic ranges. The invention also relates to the electrostatic speakers produced by this method of manufacture.

The invention is directed to an orthopaedic apparatus 24, 80, 380, 480, 580 for positioning an implant 22, 322, 422 relative to an end of a bone. The implant has at least one extractor opening 30, 330, 430 and a shoulder 26, 326, 426 with a slot therein. The positioning apparatus includes a shaft 32, 82, 382, 482 having a fixed impactor tip at an end thereof. The impactor tip is configured to be received within the implant slot. At least one clamping jaw is connected to the shaft, and includes a projection which is configured to be received in the at least one extractor opening. The at least one clamping jaw is preferably detachably connected to the shaft.
