A vertical type audio jack connector comprises an insulative housing, a plurality of terminals, an LED and a shielding case. A transducer is in communication with the signal generator to receive the plurality of signals from the signal generator. Offset spacers can then be formed that contact the opposing side surfaces of the gate. The upper profiled edge section is a hollow profiled section formed to a double bar that extends peripherally and transversely to the vertical rods and is shaped to have inner and outer wave profiles engaging one another. With the magnetic head, demagnetization produced in the recording track of the magnetic tape is prevented from being produced.
