ABSTRACT:
A headphone has an electroacoustic transducing device for converting an electrical signal to an acoustic signal, a housing for housing the electroacoustic transducing device, a flexible support member of which one end is fixed to the housing, and a vibration member disposed at the other end of the flexible support member. The vibration member generates primary vibrations by an electrical signal having a specific correlation to the electrical signal supplied to the electroacoustic transducing device. The resulting primary vibrations are transmitted through the flexible support member to the housing which then generates secondary vibrations. Unlike the impact vibrations of the primary vibrations, the secondary vibrations felt through the entire housing provide pleasant vibrations similar to air vibrations of the low bass sounds simultaneously to the corresponding low range sounds reaching the eardrum. Thus, low range sounds with dynamics exceeding the output limits of the electroacoustic transducing device is achieved.
