Abstract:
An audiofrequency signal adapter comprising:(a) an audio cassette shaped housing with a at least a pair of spindles being rotatably mounted in the cassette housing, the spindles being drivingly rotatable, whereby when the cassette housing is placed into a cassette player deck, the spindles are synchronously rotated for maintaining the normal operation of the cassette player, a rear side of the cassette housing being formed with a receptacle;(b) an adapting circuit including a coupled magnetic head and a signal compensation circuit, the coupled magnetic head being resiliently slidably disposed in a front side of the cassette housing, whereby when the cassette housing is inserted into the cassette player deck, the coupled magnetic head is resiliently correspondingly coupled with a magnetic head in the deck, the signal compensation circuit being fixedly mounted in the cassette housing and connected with the coupled magnetic head, the signal compensation circuit having an outwardly extending signal wire for connecting with an external audio signal source; and(c) a wire locating member, a first end of the wire locating member being pivotally disposed in a first end of the receptacle of the rear side of the cassette housing, whereby the wire locating member can be rotated outwardly or inwardly and totally received in the receptacle, the wire locating member being formed with multiple notches, the signal wire of the signal compensation circuit being conducted out of the cassette through one of the notches, whereby the signal wire can selectively ride in one of the notches of the wire locating member and after the wire locating member is rotated inward and latched in the cassette housing, a direction in which the signal wire is conducted out of the cassette housing is firmly fixed.
