First claim
Opening claim text (preview).
1 . A headphone device comprising an ear pad; and a sound generator comprising: a plate; and a drive system configured to convert electrical signals into mechanical oscillations of the plate. 2 . The headphone device as set forth in claim 1 , further comprising: a flexible portion arranged between the ear pad and the plate. 3 . The headphone device as set forth in claim 1 , further comprising: a piezoelectric film arranged on one side of the plate for exciting the plate. 4 . The headphone device as set forth in claim 1 ; wherein the drive system comprises: a magnet system; and a voice coil; wherein the voice coil is coupled to the plate. 5 . The headphone device as set forth in claim 1 ; wherein the drive system in the form of a capacitive drive system. 6 . The headphone device as set forth in claim 1 , further comprising: a frequency crossover configured to separate input signals into higher-frequency of lower-frequency signals; wherein the higher-frequency signals are fed to the piezoelectric film and the lower-frequency signals are fed to the drive system. 7 . The headphone device as set forth in claim 1 ; wherein the plate is formed from glass or a transparent material. 8 . The headphone device as set forth in claim 1 ; wherein the drive system is arranged in the ear pad. 9 . A sound transducer comprising: a sound generator comprising: a substantially rigid plate; and a drive system configured to convert electrical signals into mechanical oscillations of the plate. 10 . The sound transducer as set forth in claim 8 , further comprising: a flexible portion arranged between the plate and a fixing unit; wherein the flexible portion is in the form of a corrugation.
