Claim:
1. An electronic semi active control engine mount having a variable air chamber, comprising: a variable air chamber diaphragm that absorbs an exciting force of a fluid by elastically deforming, the exciting force caused by an external force; a fork that is separated from the variable air chamber diaphragm to keep an internal space of the variable air chamber into which air flows in idling of an engine and that comes in close contact with the variable air chamber diaphragm to remove the internal space of the variable air chamber into which the air flows when driving of a vehicle; and an actuator that either separates the fork from the variable air chamber diaphragm or brings the fork in close contact with the diaphragm, wherein the variable air chamber supports the variable air chamber diaphragm with an atmospheric pressure, wherein the fork is disposed under the variable air chamber diaphragm and the actuator is disposed under the fork, wherein the fork and the actuator are connected by fixing pins, and wherein the fixing pins fix a fork rod integrally formed with the fork and a fork connection rod retracting and stretching into and out of the actuator.
