发明名称 Closed headphones with transducer system
摘要 Headphones of various designs and types of construction, in particular also closed headphones, have been known for a long time. Headphones of the type mentioned above should have the desired frequency response in all frequency positions and, in particular, this frequency response should be as linear and uniform as possible in the lower frequency range in order to allow good transmission in low frequencies as well. It is the object of the invention to simplify the damping of the fundamental resonance of transducer systems, to improve quality and to save costs. Closed headphones with an acoustic transducer with a diaphragm system which separates a front volume from a rear volume, the rear volume being so small that it does not act as a spring in the range of the fundamental resonance of the transducer system.
