ACOUSTIC TRANSMISSION CONNECTION, HEADSET WITH ACOUSTIC TRANSMISSION CONNECTION, AND USES OF THE ACOUSTIC TRANSMISSION CONNECTION |
摘要 |
An acoustic transmission connection, e.g. for a headset (13), comprises a sound tube (2) through which speech signals can be transmitted from a first end (16) to a transducer, e.g. a microphone, in a housing or a housing part (3) of the headset.
