Abstract

PURPOSE:To fix the sound image outside the head of the listener without impairing the stereo audition by applying the channel signal of one side to the 1st coil if the two voice coils and the other channel signal the phase of which is shifted to the 2nd coil respectively. CONSTITUTION:Voice coil c is wound round cylindrical coil winding frame 2 of diaphragm 1, and frame 2 is positioned into the magnetic field gap formed between center pole 6 and yoke 7. And 1st and 2nd coils 4 and 5 are wound concentrically round frame 2. In such way, the head phone is formed. The 1st coil 4 of the diaphragm's voice coil for the right ear of the head phone is connected to the right channel, and 2nd coil 5 is connected to left channel L via phase shift circuit 14. Furthermore, the 2nd coil of diaphragm Ls for the left ear is connected to the right channel via phase shift circuit 13. As a result, 1st and 2nd coils 4 and 5 are driven by the direct sound signal sent from one channel and the indirect sound signal sent from the other channel respectively.
