Headphone operating on the two-way system

Abstract

The headphone comprises a low frequency transducer system and a high frequency transducer system, with the low frequency transducer system including an electrodynamic transducer. The high frequency transducer system includes an electrostatic transducer, and a supply transformer for the high frequency transducer system is mounted in the housing of the headphone. The two transducer systems are mounted coaxially of each other, with the high frequency transducer system being outwardly of the low frequency transducer system. The high frequency system may have a disc form or may have an annular form and, in the latter case, the inner diameter of the high frequency system corresponds to the outer diameter of the low frequency system which is received in a circular recess of the high frequency system. Also, the inner diameter of the annular high frequency system corresponds to the dimensions of a sound channel which, together with the cavity formed between the diaphragm of the low frequency transducer and the backside of the high frequency transducer, forms a Helmholtz resonator. For dividing the range of frequencies, acoustics and/or electrical elements are provided and are mounted in the housing of the headphone.
